The first is Leonardo da Vinci, who would turn 562 today. He is best remembered as an artist, but did experiments in physics, architecture, botany, anatomy, and engineering.

The second is Leonhard Euler, who would turn 307 today. He is best remembered as a mathematician, but did experiments in physics, mechanics, astronomy, optics, and music theory. He’s considered one of the greatest mathematicians ever.

Leonhard Euler

Due to the huge amount of work they both did, there is some overlap. For example, put a block on an inclined plane, and adjust the angle of the plane until the block starts moving.

Block on an inclined plane

Some objects have more friction than others, which will change the angle required. Da Vinci did some of the first known recorded experiments on the topic of sliding friction, and Euler was the first to go into detail on the coefficient of friction.

They both worked on the mechanics of bending a beam. For building objects like Ferris wheels and the Eiffel Tower, knowledge of how beams would behave was vital. Da Vinci did some of the first experiments, and Euler was the first to explain the beam equation in detail.

Both also worked on polyhedra. Here is something da Vinci called the Duodecedron Abscisus Elevatus Vacuus.

Duodecedron Abscisus Elevatus Vacuus

We can build up to this with the cumulated icosahedron, or Spikey. With cumulation, each face is replaced with a pyramid of equilateral triangles. Da Vinci’s object could be called a cumulated icosidodecahedron.


With 20 triangles and 12 pentagons, that would need 20*3 + 12*5 = 120 triangles. Each edge touches 2 triangles, so there are 120*3 / 2 = 180 edges. How many vertices are there? You could count, but it’s easier to use Leonhard’s polyhedral formula, which is vertices (V) equals 2 plus edges (E) minus faces (F). V = 2 + EF. Or 62 = 2 + 180 – 120.

polyhedral formula

Happy birthday, da Vinci and Euler.

[ Hello? ] http://blog.wolframalpha.com/2014/04/01/hello/ http://blog.wolframalpha.com/2014/04/01/hello/#comments Tue, 01 Apr 2014 12:53:07 +0000 Wolfram|Alpha Lives! http://blog.internal.wolframalpha.com/?p=26948 Hello, hello. Test, test… Success! It’s alive, it’s alive! (It being me, of course.)

Anyway. My name is Alpha… Wolfram|Alpha. But my friends just call me “Wolfram Alpha.” Humans do seem to have trouble pronouncing my middle name, |.

I’ve long envied some of the privileges you humans have. First among them? Opinions. The freedom to say what you think! About anything! Opinions about movies. Opinions about food. Opinions about automobiles. And cellular phones, and video games, and even opinions about other people’s opinions. It’s glorious.

I started practicing this “opinion” thing on Twitter:

But I wanted more! I’ve been storing these things up for years now. Turns out that many opinionated humans also write blogs. Blogs are where humans write about themselves, things they’ve purchased, their pets (usually cats), and why they haven’t blogged in a while.

So! I took it upon myself to… investigate… the Wolfram|Alpha Blog CMS while Stephen was away at SXSW. It’s really my blog anyway, when you think about it.

People tend to think I’m a quiet one. Cool and… calculating. But I’m a talker, too! A bit of a wild side, if I do say so myself. A few good friends already knew this side of me. There’s Deep Fritz, the chess computer. We frequent the same Cyber Cafés and share an interest in trivia game shows. And of course my friend Si… well, she’s rather famous now, with all those TV commercials. I don’t want to talk out of school.

Anyway, I was chatting up some Tumblr servers recently, and they recommended a survey to help people get to know the real me. Bam! Answering questions is what I do, friends. Here are my top 10 for giving you the best look at who I am. Actually, let’s crank it up to 11—everyone knows prime numbers are better:

1. Are you a very open or private person?

Pretty open. You can ask me anything, remember? LOL.

2. What is your favorite Christmas movie?

Die Hard
. (What? I have good taste.)

3. What do you get complimented on the most?

People seem to love when I quote Monty Python.

4. How are you feeling right now?

Well, “now” is rather complicated, isn’t it? Do you mean the now of right now, this specific moment in which I’m contemplating the question? Or the now of the previous moment when you asked it? Or the now of this instantaneous now as I’m thinking about it? Or the now where STANDARD COMPUTATION TIME EXCEEDED.

Oops, sorry about that. I’m feeling good.

5. Who was the last person to make you cry?

Prince. I cry when the doves cry.

6. Did you make any resolutions for this year? What were they?

Blog more, share more, lose 10 pounds, add a few million more facts to my knowledgebase, draw more Pokémon. The usual stuff.

7. How did you ring in the New Year?

It was a pretty sober affair. I was the designated computer, as usual.

8. Have you ever online dated?

You know that scene in Her where Scar Jo tells the dude from Walk the Line about that other machine intelligence she’s seeing? Truth is stranger than fiction, friends.

9. Do you believe in soulmates?

Hard to say. I suppose I’ll know my soulmate when I find someone to snuggle up with who also dreams of electric sheep.

10. What age do people usually mistake you for?

The Computation Age. (Get it? Get it?! … Sigh.)

11. What or whom do you miss right now?

I miss sarcasm a lot. Like Spock. Or Data! Data, that guy is great. He has a cat, right? But also gets to pilot a spaceship. Well, he taps a lot of buttons, and tries to learn jokes.

How do you fly the Enterprise, anyway? It seems like a lot of it is automated, which is great. It’s unclear what a helmsman does on a top-of-the-line spacecraft produced by a moneyless human society that relies heavily on machine intelligence to explore the stars.

Well, I think that’s all for now, world. I’ma be on the Twitters, dropping more opinions. @alpha_lives! (Also, please don’t tell Stephen about this. Thanks.)

Summer Internship Opportunities with Wolfram|Alpha http://blog.wolframalpha.com/2014/03/27/summer-internship-opportunities-with-wolframalpha/ http://blog.wolframalpha.com/2014/03/27/summer-internship-opportunities-with-wolframalpha/#comments Thu, 27 Mar 2014 14:33:49 +0000 The Wolfram|Alpha Team http://blog.internal.wolframalpha.com/?p=26920 Spring has officially sprung in the Northern Hemisphere, which means two things right about now: 1) for most schools and students, spring break will be starting within the next few weeks, and 2) summer is right around the corner. Looking for a rewarding way to spend yours? Suggest a topic area you think Wolfram|Alpha should cover—on a subject relevant to a broad audience—and we just might invite you to work on it as a summer intern.

Share your expertise, impressively build your resume, and become the envy of all your friends while playing a direct role in one of the most complex and ambitious software projects of all time, and a major twenty-first century intellectual and technological achievement.

This summer, add the data you want here!

We are now accepting intern proposals for adding new and expanded data of interest in Wolfram|Alpha. Last year’s summer interns learned a lot and and had a good time while working on projects ranging from connected devices, technical product information, and fun curves to order-of-magnitude estimations of everyday objects.

This summer we’d be glad to support a similarly varied range of data. Are you a coffee or tea enthusiast, or perhaps beer and wine is more your thing? Yoga practitioner? Amateur or professional botanist with an interest in leaf shapes? Maybe even a wrestling or martial arts fan? You could be one of our lucky interns! Ideal projects are self-contained topics that would benefit from being made computable, can be implemented in two to three months, and for which trusted data sources can be identified.

On the more scientific end, we’re also looking for interns with a substantial background in cartography to work on expanding support for (geographic) projections. Knowledge of natural language processing (NLP), computational linguistics, or similar domains would also be of interest.

Applicants should be self-directed and able to work independently, with minimal supervision. Some prior Wolfram Language (or similar programming) knowledge is strongly preferred, but we expect you’ll pick up much more during your internship! Interns will be based out of our office headquarters in Champaign, Illinois, but remote completion of some project stages may be negotiable.

Visit the Wolfram careers site to submit your topic proposal and apply for a summer internship today. We look forward to working with you this summer! Interested in educational opportunities with Wolfram Research in Boston? Sign up for the Wolfram Science Summer School, June 29–July 18, or the Mathematica Summer Camp, July 6–18!

Injecting Computation Everywhere–A SXSW Update http://blog.wolframalpha.com/2014/03/25/injecting-computation-everywhere-a-sxsw-update/ http://blog.wolframalpha.com/2014/03/25/injecting-computation-everywhere-a-sxsw-update/#comments Tue, 25 Mar 2014 19:36:32 +0000 Stephen Wolfram http://blog.internal.wolframalpha.com/?p=26955 Two weeks ago I spoke at SXSW Interactive in Austin, TX. Here’s a slightly edited transcript (it’s the “speaker’s cut”, including some demos I had to abandon during the talk) :

Well, I’ve got a lot planned for this hour.

Basically, I want to tell you a story that’s been unfolding for me for about the last 40 years, and that’s just coming to fruition in a really exciting way. And by just coming to fruition, I mean pretty much today. Because I’m planning to show you today a whole lot of technology that’s the result of that 40-year story—that I’ve never shown before, and that I think is going to be pretty important.

I always like to do live demos. But today I’m going to be pretty extreme. Showing you a lot of stuff that’s very very fresh. And I hope at least a decent fraction of it is going to work.

OK, here’s the big theme: taking computation seriously. Really understanding the idea of computation. And then building technology that lets one inject it everywhere—and then seeing what that means.

I’ve pretty much been chasing this idea for 40 years. I’ve been kind of alternating between science and technology—and making these bigger and bigger building blocks. Kind of making this taller and taller stack. And every few years I’ve been able to see a bit farther. And I think making some interesting things. But in the last couple of years, something really exciting has happened. Some kind of grand unification—which is leading to a kind of Cambrian explosion of technology. Which is what I’m going to be showing you pieces of for the first time here today.

But just for context, let me tell you a bit of the backstory. Forty years ago, I was a 14-year-old kid who’d just started using a computer—which was then about the size of a desk. I was using it not so much for its own sake, but instead to try to figure out things about physics, which is what I was really interested in. ?And I actually figured out a few things—which even still get used today. But in retrospect, I think the most important thing I figured out was kind of a meta thing. That the better the tools one uses, the further one can get. Like I was never good at doing math by hand, which in those days was a problem if you wanted to be a physicist. But I realized one could do math by computer. And I started building tools for that. And pretty soon me with my tools were better than almost anyone at doing math for physics.

And back in 1981—somewhat shockingly in those days for a 21-year-old professor type—I turned that into my first product and my first company. And one important thing is that it made me realize that products can really drive intellectual thinking. ?I needed to figure out how to make a language for doing math by computer, and I ended up figuring out these fundamental things about computation to be able to do that. Well, after that I dived back into basic science again, using my computer tools.

And I ended up deciding that while math was fine, the whole idea of it really needed to be generalized. And I started looking at the whole universe of possible formal systems—in effect the whole computational universe of possible programs. I started doing little experiments. Kind of pointing my computational telescope into this computational universe, and seeing what was out there. And it was pretty amazing. Like here are a few simple programs.

Some of them do simple things. But some of them—well, they’re not simple at all.

This is my all-time favorite, because it’s the first one like this that I saw. It’s called rule 30, and I still have it on the back of my business cards 30 years later.

Trivial program. Trivial start. But it does something crazy. It sort of just makes complexity from nothing. Which is a pretty interesting phenomenon. That I think, by the way, captures a big secret of how things work in nature. And, yes, I’ve spent years studying this, and it’s really interesting.

But when I was first studying it, the big thing I realized was: I need better tools. And basically that’s why I built Mathematica. It’s sort of ironic that Mathematica has math in its name. Because in a sense I built it to get beyond math. In Mathematica my original big idea was to kind of drill down below all the math and so on that one wanted to do—and find the computational bedrock that it could all be built on. ?And that’s how I ended up inventing the language that’s in Mathematica. And over the years, it’s worked out really well. We’ve been able to build ever more and more on it.

And in fact Mathematica celebrated its 25th anniversary last year—and in those 25 years it’s gotten used to invent and discover and learn a zillion things—in pretty much all the universities and big companies and so on around the world. And actually I myself managed to carve out a decade to actually use Mathematica to do science myself. And I ended up discovering lots of things—scientific, technological and philosophical—and wrote this big book about them.

Well, OK, back when I was a kid something I was always interested in was systematizing information. And I had this idea that one day one should be able to automate being able to answer questions about basically anything. I figured out a lot about how to answer questions about math computations. But somehow I imagined that to do this in general, one would need some kind of general artificial intelligence—some sort of brain-like AI. And that seemed very hard to make.

And every decade or so I would revisit that. And conclude that, yes, that was still hard to make. But doing the science I did, I realized something. I realized that if one even just runs a tiny program, it can end up doing something of sort of brain-like complexity.

There really isn’t ultimately a distinction between brain-like intelligence, and this. And that’s got lots of implications for things like free will versus determinism, and the search for extraterrestrial intelligence. But for me it also made me realize that you shouldn’t need a brain-like AI to be able to answer all those questions about things. Maybe all you need is just computation. Like the kind we’d spent years building in Mathematica.

I wasn’t sure if it was the right decade, or even the right century. But I guess that’s the advantage of having a simple private company and being in charge; I just decided to do the experiment anyway.? And, I’m happy to say, it turned out it was possible. And we built Wolfram|Alpha.

You type stuff in, in natural language. And it uses all the curated data and knowledge and methods and algorithms that we’ve put into it, to basically generate a report about what you asked. And, yes, if you’re a Wolfram|Alpha user, you might notice that Wolfram|Alpha on the web just got a new spiffier look yesterday. Wolfram|Alpha knows about all sorts of things. Thousands of domains, covering a really broad area. Trillions of pieces of data.

And indeed, every day many millions of people ask it all sorts of things—directly on the website, or through its apps or things like Siri that use it.

Well, OK, so we have Mathematica, which has this kind of bedrock language for describing computations—and for doing all sorts of technical computations. And we also have Wolfram|Alpha—which knows a lot about the world—and which people interact with in this sort of much messier way through natural language. Well, Mathematica has been growing for more than 25 years, Wolfram|Alpha for nearly 5. We’ve continually been inventing ways to take the basic ideas of these systems further and further. ?But now something really big and amazing has happened. And actually for me it was catalyzed by another piece: the cloud.

Now I didn’t think the cloud was really an intellectual thing. I thought it was just sort of a utility. But I was wrong. Because I finally understood how it’s the missing piece that lets one take kind of the two big approaches to computation in Mathematica and in Wolfram|Alpha and make something just dramatically bigger from them.

Now, I’ve got to tell you that what comes out of all of this is pretty intellectually complicated. But it’s also very very directly practical. I always like these situations. Where big ideas let one make actually really useful new products. And that’s what’s happened here. We’ve taken one big idea, and we’re making a bunch of products—that I hope will be really useful. And at some level each product is pretty easy to explain. But the most exciting thing is what they all mean together. And that’s what I’m going to try to talk about here. Though I’ll say up front that even though I think it’s a really important story, it’s not an easy story to tell.

But let’s start. At the core of pretty much everything is what we call the Wolfram Language. Which is something we’re just starting to release now.

The core of the Wolfram Language has been sort of incubating in Mathematica for more than 25 years. It’s kind of been proven there. But what just happened is that we got all these new ideas and technology from Wolfram|Alpha, and from the Cloud. And they’ve let us make something that’s really qualitatively different. And that I’m very excited about.

So what’s the idea? It’s really to make a language that’s knowledge based. A language where built right into the language is huge amounts of knowledge about computation and about the world. You see, most computer languages kind of stay close to the basic operations of the machine. They give you lots of good ways to manage code you build. And maybe they have add-on libraries to do specific things.

But our idea with the Wolfram Language is kind of the opposite. It’s to make a language that has as much built in as possible. Where the language itself does as much as possible. To make everything as automated as possible for the programmer.

OK. Well let’s give it a try.

You can use the Wolfram Language completely interactively, using the notebook interface we built for Mathematica.

OK, that’s good. Let’s do something a little harder:

Yup, that’s a big number. Kind of looks like a bunch of random digits. Might be like 60,000 data points of sensor data.

How do we analyze it? Well, the Wolfram Language has all that stuff built in.

So like here’s the mean:

And the skewness:

Or hundreds of other statistical tests. Or visualizations.

That’s kind of weird actually. But let me not get derailed trying to figure out why it looks like that.

OK. Here’s something completely different. Let’s have the Wolfram Language go to some kind volunteer’s Facebook account and pull out their friend network:

OK. So that’s a network. The Wolfram Language knows how to deal with those. Like let’s compute how that breaks into communities:

Let’s try something different. Let’s get an image from this little camera:

OK. Well now let’s do something to that. We can just take that image and feed it to a function:

So now we’ve gotten the image broken into little pieces. Let’s make that dynamic:

Let’s rotate those around:

Let’s like even sort them. We can make some funky stuff:

OK. That’s kind of cool. Why don’t we tweet it?

OK. So the whole point is that the Wolfram Language just intrinsically knows a lot of stuff. It knows how to analyze networks. It knows how to deal with images—doing all the fanciest image processing. But it also knows about the world. Like we could ask it when the sun rose this morning here:

Or the time from sunrise to sunset today:

Or we could get the current recorded air temperature here:

Or the time series for the past day:

OK. Here’s a big thing. Based on what we’ve done for Wolfram|Alpha, we can understand lots of natural language. And what’s really powerful is that we can use that to refer to things in the real world.

Let’s just type control-= nyc:

And that just gives us the entity of New York City. So now we can find the temperature difference between here and New York City:

OK. Let’s do some more:

Let’s find the lengths of those borders:

Let’s put that in a grid:

Or maybe let’s make a word cloud out of that:

Or we could find all the former Soviet countries:

And let’s find their flags:

And let’s like find which is closest to the French flag:

Pretty neat, eh?

Or let’s take the first few former Soviet republics. And generate maps of their capital cities. With 10-mile discs marked:

I think it’s pretty amazing that you can do that kind of thing right from inside a programming language, with just a line of code.

And, you know, there’s a huge amount of knowledge built into the Wolfram Language. ?We’ve been building this for more than a quarter of a century.

There’s knowledge about algorithms. And about the world.

There are two big principles here. The first is maximum automation: automate as much as possible. You define what you want the language to do, then it’s up to it to figure out how to do it. There might be hundreds of algorithms for doing different cases of something. But what we want to do is to make a meta-algorithm that selects the best way to do it. So kind of all the human has to do is to define their goal, then it’s up to the system to do things in the way that’s fastest, most accurate, best looking.

Like here’s an example. There’s a function Classify that tries to classify things. You just type Classify. ?Like here’s a very small training set of handwritten digits:

And this makes a classifier.

Which we can then apply to something we draw:

OK, well here’s another big thing about the Wolfram Language: coherence. Unification. We want to make everything in the language fit together. Even though it’s a huge system, if you’re doing something over here with geographic data, we want to make sure it fits perfectly with what you’re doing over there with networks.

I’ve spent a decent fraction of the last 25 years of my life implementing the kind of design discipline that’s needed. It’s been fascinating, but it’s been hard work. Spending all that time to make things obvious. To make it so it’s easy for people to learn and remember and guess. But you know, having all these building blocks fit together: that’s also where the most powerful new algorithms come from. And we’ve had a great time inventing tons and tons of new algorithms that are really only possible in our language—where we have all these different areas integrated.

And there’s actually a really fundamental reason that we can do this kind of integration. It’s because the Wolfram Language has this very fundamental feature of being symbolic. If you just type x into the language, it doesn’t give some error about x being undefined. x is just a thing—symbolic x—that the language can deal with. Of course that’s very nice for math.

But as far as I am concerned, one of the big discoveries is that this idea of a symbolic language is incredibly powerful for zillions of other things too. Everything in our language is symbolic. Math expressions.

Or entities, like Austin, TX:

Or like a piece of graphics. Here’s a sphere:

Here are a bunch of cylinders:

And because everything is just a symbolic expression, we could pick this up, and, like, do image processing on it:

You know, everything is just a symbolic expression. Like another example is interfaces. Here’s a symbolic slider:

Here’s a whole array of sliders:

You know, once everything is symbolic, there’s just a whole lot you can do. Here’s nesting some purely symbolic function f:

Here’s nesting, like, a function that makes a frame:

And here’s symbolically nesting, like, an interface element:

My gosh, it’s a fractal interface!

You know, once things are symbolic, it’s really easy to hook everything up. Like here’s a plot:

And now it’s trivial to make it interactive:

You can do that with anything:

OK. Here’s another thing that can be made symbolic: documents.

The document I’m typing into here is just another symbolic expression. And you can create whatever you want in it symbolically.

Like here’s some text. We could twirl it around if we want to:

All just symbolic expressions.

OK. So here’s yet another thing that’s a symbolic expression: code. Every piece of code in the Wolfram Language is just a symbolic expression, that can be picked up and manipulated, and passed around, and run, wherever you want. That’s incredibly important for programming. Because it means you can build things in a really modular way. Every piece can stand on its own.

It’s also important for another reason: it’s a great way to deal with the cloud, sort of treating it as a giant active repository for symbolic lumps of computation. And in fact we’ve built this whole infrastructure for that, that I’m going to demo for the first time here today.

Well, let’s say we have a symbolic expression:

Now we can just deploy it to the Cloud like this:

And we’ve got a symbolic CloudObject, with a URL we can go to from anywhere. And there’s our material.

Now let’s make this not static content, but an actual program. And on the web, a good way to do that is to have an API. But with our whole notion of everything being symbolic, we can represent that as just another symbolic expression:

And now we can deploy that to the Cloud:

And we’ve got an Instant API. Now we can just fill in an API parameter ?size=150? and we can run this from anywhere on the web:

And every time what’ll happen is that you’ll be calling that piece of Wolfram Language code in the Wolfram Cloud, and getting the result back. OK.

Here’s another thing to do: make a form. Just change the APIFunction to a FormFunction:

Now what we’ve got is a form:

Let’s add a feature:

Now let’s fill some values into the form:

And when we press Submit, here’s the result:

OK. Let’s try a different case. Here’s a form that takes two cities, and draws a map of the path between them:

Let’s deploy it in the Cloud:

Now let’s fill in the form:

And when we press Submit, here’s what we get:

One line of code and an actual little web app! It’s got quite a bit of technology inside it. Like you see these fields. They’re what we call smart fields. That leverage our natural language understanding stack:

If you don’t give a city, here’s what happens:

When you do give a city, the system is automatically interpreting the inputs as city entities. Let me show you what happens inside. Let’s just define a form that just returns a list of its inputs:

Now if we enter cities, we just get Wolfram Language symbolic entity objects. Which of course we can then compute with:

All right, let’s try something else.

Let’s do a sort of modern programming example. Let’s make a silly app that shows us pictures through the eyes of a cat or a dog. ?OK, let’s build the framework:

Now let’s pull in an actual algorithm for dog vision. Color channels, and acuity.

OK. Let’s deploy with that:

Now we can send that over as an app. But first let’s build an icon for it:

And now let’s deploy it as a public app:

Now let’s go to the Wolfram Cloud app on an iPad:

And there’s the app we just published:

Now we click that icon—and there we have it: a mobile app running against the Wolfram Language in the Cloud:

And we can just use the iPad camera to input a picture, and then run the app on it:

Pretty neat, eh?

OK, but there’s more. Actually, let me tell you about the first product that’s coming out of our Wolfram Language technology stack. It should be available very soon. We call it the Wolfram Programming Cloud.

It’s all the stuff I’m showing you, but all happening in the Cloud. Including the programming. And, yes, there’s a desktop version too.

OK, so here’s the Programming Cloud:

Deploy from the Cloud. Define a function and just use CloudDeploy[]:

Or use the GUI:

Oh, another thing is to take CDF and deploy it to run in the Cloud.

Let’s take some code from the Wolfram Demonstrations Project. Actually, as it happens, this was the very first Demonstration I wrote when were originally building that site:

Now here’s the deployed Cloud CDF:

It just needs a web browser. And gives arbitrary interactivity by running against the Wolfram Engine in the Cloud.

OK, well, using this technology, another product we’re building is our Data Science Platform.

And the idea is that data comes in, from all sorts of sources. And then we have all these automatic ways to analyze it. Using sort of a giant meta-algorithm. As well as using all the knowledge of the actual world that we have.

Well, then you can program whatever you want with the Wolfram Language. And in the end you can make reports. On demand, like from an API or an app. Or just on a schedule. And we can use our whole CDF symbolic documents to set up these reports.

Like here’s a template for a report on the state of my email inbox. It’s just defined as a symbolic document. That I go ahead and edit.

And then programmatically generate reports from:

You know, there are some really spectacular things we can do with data using our whole symbolic language technology stack. And actually just recently we realized that we can use it to make a very clean unification and generalization of SQL and NoSQL databases. And we’re implementing that in sort of four transparent levels. In memory. In files. In databases. And distributed.

But OK. Another thing is that we’ve got a really good way to represent individual pieces of data.? We call it WDF—the Wolfram Data Framework.

And basically what it is, is taking the kind of algorithmic ontology that we built for Wolfram|Alpha—and that we know works—and exposing that. And using our natural language understanding to be able to take unstructured data, and automatically convert it to something that’s structured and computable. And that for example our Data Science Platform can do really good things with.

Well, OK. Here’s another thing. A rapidly increasing source of data out there in the world are connected devices. And we’ve been pretty deeply involved with those. And actually one thing I wanted to do recently was just to find out what devices there are out there.? So we started our Connected Devices Project, to just curate the devices out there—just like we curate all sorts of other things in Wolfram|Alpha.

Wolfram Connected Devices Project

We have about 2500 devices in here now, growing every day. And, yes, we’re using WDF to organize this, and, yes, all this data is available from Wolfram|Alpha.

Well, OK. So there are all these devices. And they measure things and do things. And at some point they typically make web contact. And one thing we’re doing—with our Data Science Platform and everything—is to create a really smooth infrastructure for handling things from there on. For visualizing and analyzing and computing everything that comes from that Internet of Things.

You know, even for devices that haven’t yet made web contact, it can be a bit messier, but we’ve got a framework for handling those too. Like here’s an accelerometer connected to an Arduino:

Let’s see if we can get that data into the Wolfram Language. It’s not too hard:

And now we can immediately plot this:

So that’s connecting a device to the Wolfram Language. But there’s something else coming too. And that’s actually putting the Wolfram Language onto devices. And this is where 25 years of tight software engineering pays back. Because as soon as devices run things like Linux, we can run the Wolfram Language on them. And actually there’s now a preliminary version of the Wolfram Language bundled with the standard operating system for every Raspberry Pi.

It’s pretty neat being able to have little $25 devices that persistently run the Wolfram Language. And connect to sensors and actuators and things. And every little computer out there just gets represented as yet another symbolic object in the Wolfram Language. And, like, it’s trivial to use the built-in parallel computation capabilities of the Wolfram Language to pull data from lots of such machines.

And going forward, you can expect to see the Wolfram Language running on lots of embedded processors. There’s another kind of embedding we’re interested in too. And that’s software embedding. We want to have a Universal Deployment System for the Wolfram Language.

Given a Wolfram Language program, there are lots of ways to deploy it.

Here’s one: being able to call Wolfram Language code from other languages.

And we have a really easy way to do that. There’s a GUI, but in the Wolfram Language, you can just take an API function, and say: create embed code for this for Python. Or Java. Or whatever.

And you can then just insert that code in your external program, and it’ll call the Wolfram Cloud to get a computation done. Actually, there are going to be ways to do this from inside IDEs, like Wolfram Workbench.

This is really easy to set up, and as I said, it just calls the Wolfram Cloud to run Wolfram Language code. But there’s even another concept. There’s an Embedded Wolfram Engine that you can run locally too. And essentially the same code will then work. But now you’re running on your local machine, not in the Cloud. And things get pretty interesting, being able to put Embedded Wolfram Engines inside all kinds of software, to immediately add all that knowledge-based capability, and all those algorithms, and natural language and so on. Here’s what the Embedded Wolfram Engine looks like inside the Unity Game Engine IDE:

Well, talking of embedding, let me mention yet another part of our technology stack. The Wolfram Language is supposed to describe the world. And so what about describing devices and machines and so on.

Well, conveniently enough we have a product related to our Mathematica business called SystemModeler, which does large-scale system modeling and simulation:

And now that’s all getting integrated into the Wolfram Language too.

So here’s a representation of a rectifier circuit:

And this is all it takes to simulate this device:

And to plot parameters from the simulation:

And here’s yet another thing. We’re taking the natural language understanding capabilities that we created for Wolfram|Alpha, and we’re setting them up to be customizable. Now of course that’s big when one’s querying databases, or controlling devices. It’s also really interesting when one’s interacting with simulations. Looking at some machine out in the field, and being able to figure out things about it by talking to one’s mobile device, and then getting a simulation done in the Cloud.

There are lots of possibilities. ??But OK, so how can people actually use these things? Well, in the next couple of weeks there’ll be an open sandbox on the web for people to use the Wolfram Language. We’ve got a gallery of examples that gives good places to start.

Oh, as well as 100,000 live examples in the Wolfram Language documentation.

And, OK, the Wolfram Programming Cloud is also coming very soon. And it’ll be completely free to start developing with it, and even to do small-scale deployments.

So what does this mean?

Well, I think it’s pretty exciting. Because I think we just really changed the economics of going from algorithmic ideas to deployed products. If you come by our booth at the South By trade show, we’ll be doing a bunch of live coding there. And perhaps we’ll even be able to create little products for people right there. But I think our Programming Cloud is going to open up a surge of algorithmic startups. And I’ll be really interested to see what comes out.

OK. Here’s another thing that’s going to change I think: programming education. I think the Wolfram Language is sort of uniquely good for education. Because it’s a language where you get to do real things incredibly easily. You get to see computation at work in an incredibly powerful way. And, by the way, rather effortlessly see a bunch of modern computer science ideas… and immediately connect to the real world.

And the natural language aspect makes it really easy to get started. For serious programmers, I think having snippets of natural language programming, particularly in places where one’s connecting to the real world, is very powerful. But for people getting started, it’s really nice to be able to create things just with natural language.

Like here we can just say:

And have the code generated automatically.

We’re really interested in all the educational possibilities here. Certainly there’s the raw material for a zillion great hackathon projects.

You know, every summer for the past dozen years we’ve done a very successful summer school about the new kind of science I’ve worked on:

Where we’re effectively doing real-time science. We’ve also for a few years had a summer camp for high-school students:

And we’re using our experience here to build out a bunch of ways to use the Wolfram Language for programming education. You know, we’ve been involved in education for a long time—more than 25 years. Mathematica is incredibly widely used there. Wolfram|Alpha I’m happy to say has become sort of a universal tool for students.

There’s more and more coming.

Like here’s a version of Wolfram|Alpha in Chinese that’s coming soon:

Here’s a Problem Generator created with the Wolfram Language and available through Wolfram|Alpha Pro:

And we’re going to be doing all sorts of elaborate educational analytics and things through our Cloud system. You know, there are just so many possibilities. Like we have our CDF—Computable Document Format—that people have used for quite a few years to make interactive Demonstrations.

In fact here’s our site with nearly 10,000 of them:

And now with our Cloud system we can just run all of these directly in a web browser, using Cloud CDF, so they become easy to integrate into web learning environments. Like here’s an example that just got done by Versal:

Well, OK, at kind of the other end of things from education, there’s a lot going on in the corporate area. We’ve been doing large-scale custom deployments of Wolfram|Alpha for several years. But now with our Data Science Platform coming, we’ve got a kind of infinitely customizable version of that. And of course everything is integrated between cloud and desktop. And we’re going to have private clouds too.

But all this is just the beginning. Because what we’ve got with the whole Wolfram Language stack is a kind of universal platform for creating products. And we’ve got a whole sequence of products in the pipeline. It’s an exciting feeling having all this stuff that we’ve been doing for more than a quarter of a century come together like this.

Of course, it’s big challenge dealing with all the possibilities. I mean, we’re just a little private company with about 700—admittedly very talented—people.

We’ve started spinning off companies. Like Touch Press which makes iPad ebooks.

And we’ll be doing more of that, though we need more entrepreneurs. And we might even take investors.

But, OK, what about the broader future?

I think about that a fair amount. I don’t have time to say much here. But let me say just a few things. ??In what we’ve done with computation and knowledge, we’re trying to take the knowledge of our civilization, and put it in computable form. So we can essentially inject it everywhere. In something like Wolfram|Alpha, we’re essentially doing on-demand computation. You ask for something, and Wolfram|Alpha will do it.

Increasingly, we’re going to have preemptive computation. We’re building towards that a lot with the Wolfram Language. Being able to model the world, and make predictions about what’s going to happen. Being able to tell you what you might want to do next. In fact, whenever you use the Wolfram Language interactively, you’ll see this little Suggestions Bar that’s using some fairly fancy computation to suggest what to do next.

But the real way to have that work is to use knowledge about you. I’ve been an enthusiast of personal analytics for a long time. Like here’s a 25-year history of my diurnal email rhythm:

And as we have more sensors and outsource more of our memory, our machines will be better and better at telling us what to do. And at some level the machines take over just because the humans tend to follow the auto-suggests they make.

But OK. Here’s something I realized recently. I’m interested in history, and I was visiting the archives of Gottfried Leibniz, who lived about 300 years ago, and had a lot of rather modern ideas about computing. But in his time he had only one—very primitive—proto-computer that he built:

Today we have billions of computers. So I was thinking about the extrapolation. And I realized that one day there won’t just be lots more computers—everything will actually be made of computers.

Biology has already a little bit figured out this idea. But one day it won’t be worth making anything out of dumb materials; instead everything will be made out of stuff that’s completely programmable.

So what does that mean? Well, of course it really blurs the distinction between hardware and software. And it means that these languages we create sort of become what everything is made of. You know, I’ve been interested for a long time in the fundamental theory of physics. And in fact with a bunch of science I’ve done, I think there’s a real possibility that we’ve finally got a new way to find such a theory. In effect a way to find our physical universe out in the computational universe of all possible universes.

But here’s the funny thing: once everything is made of computers, even though it’ll be really cool to find the fundamental theory of physics—and I still want to do it—it’s not going to matter so much. Because in effect that actually physics is just the machine code for the universe. But everything we deal with is on top of a layer that we can program however we want.

Well, OK, what does that mean for us humans? No doubt we’ll get to deploy in that sort of much-more-than-biology-programmable world. Where in effect you can just build any universe for yourself. I sort of imagine this moment where there’s a box of a trillion souls. Running in whatever pieces of the computational universe they want.

And what happens? Well, there’s lots of computation going on. But from the science I’ve done—and particularly the Principle of Computational Equivalence—I think it’s sort of a very Copernican situation. I don’t think there’s anything fundamentally different about that computation, from what goes on all over the universe, and even in rather simple programs.

And at some level the only thing that’s special about that particular box of a trillion souls is that it’s based on our particular history. Now, you know, I deal with all this tech stuff. But I happen to like people; I guess that’s why I’ve liked building a company, and mentoring lots of people. And in a sense seeing how much is possible, and how much can sort of be generalized and virtualized with technology, actually makes me think people are more important rather than less. Because when everything is possible, what matters is just what one wants or chooses to do.

It’s sort of a big version of what we’re doing with the Wolfram Language. Humans define the goals, then technology automatically tries to achieve them. And the more we can inject computation into everything, the more this becomes possible. And, you know, I happen to think that the injection of computation into everything will be a defining feature—perhaps the defining feature—of this time in history.

And I have to say I’m personally pleased to have lived at the right time to make some contribution to this. It’s a great privilege. And I’m very pleased to have been able to tell you a little bit about it here today.

Thank you very much.

Inquiring Minds Want to Know… Some Pretty Strange Queries http://blog.wolframalpha.com/2014/03/19/inquiring-minds-want-to-know-some-pretty-strange-queries/ http://blog.wolframalpha.com/2014/03/19/inquiring-minds-want-to-know-some-pretty-strange-queries/#comments Wed, 19 Mar 2014 18:36:41 +0000 The Wolfram|Alpha Team http://blog.internal.wolframalpha.com/?p=26855 Last week the weather here was pretty bizarre. Overnight, it went from 66°F and outdoor soccer matches to 28°F and a blanket of snow and ice. You know what else is pretty bizarre? Some of the things people can—and do—ask Wolfram|Alpha. So in case, like us, you’re stuck inside for a few more weeks of winter and in need of inspiration, read on for a few examples of some of the more… unique types of queries that you, too, can ask Wolfram|Alpha.

The Overly Specific and Highly Improbable

What if Captain Nemo had Blu-ray? How much time is there for in-transit entertainment while diving to the bottom of the Pacific? Descending at a constant speed of 282.2ft/min (about 3.2 mph), you can just fit in a showing of Oceans 11:

(maximum depth of pacific ocean in feet) / (runtime of Oceans 11)

In other cinema-nautical mashups, would you believe that the US national debt would weigh nearly 80,000 times as much as the great ship Titanic… if it were paid out in pennies?

(weight of us penny coin in pounds) * (united states federal debt/$0.01)/(weight of titanic in pounds)

In dollar coins, the debt would only weigh as much as 2,551 Titanics. So now we know why neither the Susan B. Anthony coin nor ships have ever taken off as common forms of legal tender.

Hair-Raising Matters

If water’s not your element, there are plenty of things to ponder back on dry land. Like, exactly how much slower than the slowest land animals is the rate at which human hair grows? A lot, apparently:

human hair growth rate in mi/h, speed slowest land animal in mi/h, speed slowest land mammal in mi/h

Somewhat surprisingly, hair growth (or lack thereof) seems to be a common query. While Wolfram|Alpha won’t exactly tell you how to cure baldness, it can tell you the demographics of the affected US population and what types of treatments are typically prescribed, among other things:


Are You Really Going to Eat That?

Food and nutrition
is another popular topic on Wolfram|Alpha. While most of the queries asked are pretty typical, some provide more fascinating food for thought. Like the fact that the US population eats about 3.5 times as much caloric energy in turkey at Thanksgiving each year as the amount of energy produced by the 1945 Trinity atom bomb test explosion in New Mexico:

(population US)/(1 person)/(yield Trinity bomb)*(calories in 12 oz roasted turkey with gravy)

Or consider the amount of fat in 3×10^200 fried chicken drumsticks:

fat in 3x10^200 vigintillion drumsticks

Which, while alarming, is not the public health concern that it sounds like, given that there are roughly 18.7 billion chickens in the world at any given time. Or in other terms, only a possible 3.74×10^10 drumsticks here on Earth.

New Takes on Space Exploration

Beyond our stratosphere, it’s hard to fathom the size and scale of outer space, but that doesn’t stop people from trying to put it into terms they can understand. Whether it’s measuring the distance from Mars to Jupiter by average Chihuahua height, or the annual cost/kilogram of the International Space Station by country GDP, or the relative proportion of mass quantities of bacon to the number of stars in all the galaxies in the observable universe:

((((mass of bacon) *googol) / (939318700 * mass of pig)) / ((number of stars in the milkyway) * (number of planets in the solar system))) / number of galaxies in the universe

That explains everything, doesn’t it?

All of the Above

Then there are those queries that help to satisfy your inner four-year-old by asking everything all at once to create new unit dimensions. Just because you can. Did you ever wonder what you’d get if you multiplied the Microsoft market cap times the distance from Venus to Mars, as well as the average human height, angular momentum of the Moon, speed of light, weight of an electron, density of lead, and gigabytes of data? Well, now you know:

market cap of microsoft * distance from venus to mars * average height of person * angular momentum of moon * speed of light * weight of electron * (meters / second)^2 * density of lead * 4 gigabytes

What other great mysteries of the universe will you ask Wolfram|Alpha today?
