New Features in Wolfram|Alpha: Year-End Update

December 21, 2009 —
Comments Off

When we launched Wolfram|Alpha in May 2009, it already contained trillions of pieces of information—the result of nearly five years of sustained data-gathering, on top of more than two decades of formula and algorithm development in Mathematica. Since then, we’ve successfully released a new build of Wolfram|Alpha’s codebase each week, incorporating not only hundreds of minor behind-the-scenes enhancements and bug fixes, but also a steady stream of major new features and datasets.

We’ve highlighted some of these new additions in this blog, but many more have entered the system with little fanfare. As we near the end of 2009, we wanted to look back at seven months of new Wolfram|Alpha features and functionality.

Mathematics, Statistics, and Computation

An impressive collection of advanced support for mathematical functions has been added, including more support for Bessel functions, gamma functions, elliptic functions, and zeta functions. Users will also find improved plotting for special functions.

Users will find many updates in discrete mathematics for areas like combinatorics and graph theory.

Improvements to our capabilities in probability and statistics have also been made. You can now compute any probability for any distribution that is known by Mathematica, or find the set on which the density of the statistical distribution is non-zero. You can also explore traditional areas of combinatorics such as coin flips and card playing.

Our support of computational sciences has expanded. You have more ways to explore cellular automata as well as support for string substitution systems. You can also now explore all the famous categories of fractals.

Another major area of improvement is in algebra, including better support for sums and matrix computations.

For calculus and analysis you will find more advanced support throughout Wolfram|Alpha. Some highlights include better plotting, more derivatives and integrals, more step-by-step results, better linguistics for inputting your computations, and complex analysis features such as computing the residue.

More tiling support has been added to our geometry offerings. We now support all of the most commonly used periodic tilings, such as basketweave and zigzag tiling.

Science, Biology, and Health

Our physical exercise calculator may be one of Wolfram|Alpha’s most useful new additions, allowing users to compute energy expenditure, fat loss, and oxygen consumption for dozens of different activities, from running to rowing.

To complement the information we have been providing about the human genome, we now have the genomic structure of the mouse, including information about DNA sequences relative to specific genes.

We’ve added carbon footprint data, providing information about the carbon footprint of various activities such as heating our homes or taking a road trip.

We had a massive amount of astronomical data when we first launched Wolfram|Alpha, but over the summer and fall we added a great number of solar system features, including maps of planets, data about craters of planets and moons, and detailed information about Jupiter’s Great Red Spot. We’ve also been able to add quite a bit of information about astronomical events, such as meteor showers, and their properties.

For those concerned with issues closer to home, we’ve added information about clouds and the composition of our atmosphere. We also have information about atmospheric conditions, including wind chill, humidity, location-specific heating and cooling days, and the heat index.

We’ve spoken about earthquakes before, and this domain continues to see new developments. We’ve improved Wolfram|Alpha’s ability to understand more complex queries about earthquakes in a specified place and time, and we’re currently working on several major enhancements to our display of earthquake data.

We now have information about classes of lasers, particular lasers, and their properties.

We’ve also continued to develop our offerings in the engineering domain, with a new refrigeration cycle calculator and tools for computing psychrometric properties (the physical and thermodynamic characteristics of gas-vapor mixtures).

Which came first: the canine or the incisor? Wolfram|Alpha now has data on primary (baby) and adult teeth—with physical attributes and developmental details for each individual tooth.

Wolfram|Alpha launched with extremely strong support for queries about geodesy and navigation, but we’ve continued to add new features, including support for specific map-projection requests and better handling of geodetic datum transformations.

Socioeconomics and Culture

We added more than 20 years’ worth of FBI statistics on crime in major U.S. cities. You can research and compare data on property crime and violent crime—with detailed numbers and rates for specific categories of crime such as burglary, vehicle theft, and assault.

We recently completed a major effort to add information on medals and results for every Olympic event since 1896. Users can search for results by country, year, athlete, medal type, event, and practically any combination of the above.

Wolfram|Alpha users can now compare current housing price information for most U.S. cities, and also explore decades of historical data. In addition to specific data on housing prices, Wolfram|Alpha has added ACCRA Cost of Living Index data for hundreds of U.S. cities and urban areas. You can compare the relative costs of groceries, housing, health care, transportation, and utilities in different cities, or find out what salary would be required to maintain a comparable standard of living if you moved to a new city.

We’ve begun a major project to add domestic and international health care statistics to Wolfram|Alpha. The first phase included data on public and private health expenditures in OECD countries—with data to come on health care resources, social insurance, and more.

Wolfram|Alpha can now show and compare military information—such as troop strengths, expenditures, selected armaments, and nuclear stockpiles—for most nations of the world.

We’re in the midst of a major expansion of data on cities in the U.S and around the world. Wolfram|Alpha users can now ask what county (or counties) a particular U.S. city is in, and also explore and compare the populations of metropolitan and urban areas and their member cities. We’ve also updated our city population figures to the latest available figures from the U.S. Census Bureau, and more international data is flowing in as we speak.

Wolfram|Alpha now contains salary data for virtually any occupation in the U.S., with state-level detail; we’re currently adding city- and metropolitan-area-level data, and improving our presentation of occupational categories, based on information from the U.S. Bureau of Labor Statistics.

We’ve expanded our coverage of unemployment rates. In addition to recent stats for most nations, we now have decades of historical data for U.S. states, counties, and cities.

Wolfram|Alpha also has expanded information on time zones and calendars, with ever-increasing support for international and religious calendars and time computations—as well as information on many more international holidays than we had at launch.

Wolfram|Alpha’s language data has also undergone a dramatic overhaul and update, with geographic and lexical information on literally thousands of languages, from Adele to Zanaki.

Expanded coverage of music is one of our top priorities for the next six months, but we’ve already made a number of improvements to our current presentation of music data—including the display of guitar chord voicings.

Wolfram|Alpha now has the ability to encode digits or text as barcodes, including barcodes corresponding to specific standards, such as UPC or ISBN.

For anyone interested in broadcast media, Wolfram|Alpha can now answer questions about major television networks—allowing you to compare reach, affiliates, and other properties.

We’ve continued to add more basic reference material, including the ability to find the location of an area code or specific telephone number, as well as international calling codes.

These are only a few dozen notable additions to Wolfram|Alpha’s ever-growing knowledge base over the past six months; many more existing data sets—from movies to weather to financial data—are updated weekly, daily, or even more frequently, and countless linguistic and graphic improvements have been introduced each and every week.

In 2010, we will continue to improve and update all of these domains, and to tackle entirely new areas of knowledge. Efforts are already underway to add data on an incredibly diverse array of subjects: automobiles, energy consumption and prices, fictional characters, wars and battles, and Academy Awards, to name just a small fraction. As always, we welcome your comments and suggestions, and we look forward to more exciting developments for Wolfram|Alpha in the new year.


Wow. That is really amazing. Soon Wolfram Alpha will be able to calculate anything!

Posted by George December 21, 2009 at 3:35 pm

Awesome and interesting new features.

Posted by Carlos December 21, 2009 at 5:26 pm

Great, but how about:
- expanding non-US data available,
- including different data on same subjects so that users can make informed, conscious decisions. For example “carbon footprints” as widely questioned as are US gov statistics (especially unemployment numbers and other labor related stats) – see for example

WOW! Amazing! Cannot wait to see what the next year brings!

Posted by Shellie December 21, 2009 at 6:46 pm

Wolfram Alpha, love this blog and your work is genius!

Some points:
– Understanding some basic questions are still not answered even though the answers are in the dataset
e.g. “tallest mountain in scotland”
– As already mentioned more international data would be fantastic (United Kingdom)

Overall love the service and existing dataset but do get frustrated when no answer is provided, even a google search result might be a little helpful, would then be more inclined as using this as more frequent source (instead of Google and Wikipedia).

I look forward to 2010. Many Thanks

Cellular automata is nice, but needs to have 2D structures too.

Thanx for your update today 22 Dec 2009 anout your new features and your year so far.
Have always expected great things of you.
Would appreciate your comment on one of my initial questions from very early on.
Could you advise all of us, based on the latitude and logitude of our domiciles when the planets and the sun and moon and other notable objects might be rising or setting or appearing in our loval skies?

Nice updates. I still think that the “physics” section, in particular particle physics needs a lot of work.

A way to fix it would be to contact those guys :

Posted by Zelrik December 21, 2009 at 8:01 pm

I hate the input methods on your calculators. Not intuitive at all.

Posted by Betty Kohlenberg December 21, 2009 at 8:22 pm

the site is definitely improving though still very US-centric – I did notice however that entering Richmond now gives me the UK one rather than the one in Virginia so I’m guessing you’re using the url to make Alpha more locale-aware?

Anyway really congatulations, this venture sits alongside Google and Wikipedia as probably one of the core elements of the future of the integrated knowledge/communication web that will undoubtedly be very deeply part of our lives.

Posted by malc December 21, 2009 at 8:54 pm

That’s great, but the data’s still useless if you can’t figure out how to search it. The only searches I ever get to work are simple variations on the samples, never what I think should be obvious even when I know the data is available.

Posted by Dave December 21, 2009 at 9:08 pm

I agree with Andy Brandt about expanding to non-US data or even bigger, world wide data combined by the Wolfram|Alpha engine.

Posted by Emil Hemdal December 21, 2009 at 9:47 pm

How soon do you expect to be able to respond to questions that draw upon the soon-to-be-released U.S. government openness data?

Posted by Bruce Preville December 21, 2009 at 9:50 pm

How wonderful it might be if you could hook up with Elbot. Give that churlish bot some real knowledge.

Posted by Marvin E. Walden, PhD December 21, 2009 at 9:53 pm

Even as W/A grows I’m finding it useful, and am going to it first instead of Google for topics that I have heard you mention in these blogs. For example, when I was putting together a church calendar for 2010 I needed to know the date of Easter, and went here. It’s been useful in finding simple distances, such as Detroit to Cleveland (I know I can also get that from, but I wanted to try W/A. It was faster at getting my result. I wanted to see if Muhammad Ali ever won Olympic Gold and got that answer in a flash without having to click through several web pages and scan the material. It’s getting easy for me to predict which topics you’re better at, and I’m relying on you more.

I hope that your business model allows you to survive financially so that you can be around for decades as you plan. With Wikipedia putting out financial distress signals, I’d hate to see you go the same way before you mature. In my book, I’d rather have you available with ads than have you unavailable without ads.

carbon footprints go to china or any other third world county it aint the us they just got the money , and the guilt ,

Posted by daveinnol December 21, 2009 at 10:09 pm

I agree with the above – I love the potential of Wolfram Alpha, but it seems only really useful for US data

Posted by Dane December 21, 2009 at 10:35 pm

This is cool, but the phone number locations seem a bit off after I tried them with my home numbers and others that I know offhand.

Posted by David December 21, 2009 at 11:38 pm

First of all congratulations! Your accomplishments are truly magnificent. As a scientist and computer user for more than fifty years, I am personally thrilled. Your next great challenge should be to make Alpha the essential piece of software for every computer user on the planet. How about a Silicon based Alpha operating system that can run all, Windows, Mac, and Linux, applications featuring Alpha as the “Master” application.

Posted by Edgar Kraut December 21, 2009 at 11:48 pm

What about lambda calculus?

Posted by ID December 21, 2009 at 11:55 pm

Awesome! An unbelievably vast accumulation of information and capabilities on an incredibly diverse list of subjects.

Posted by Jay Gross December 22, 2009 at 12:52 am

Really feel the lack of international info. Wolfram is more mathematics, waiting for some humanitarian sciences.

Posted by AIR December 22, 2009 at 1:52 am

A small inquiry: perhaps some functionality in a few more basic principals of chemical engineering and physical chemistry would be useful to some. These principals include enthalpy, entropy, dew point, bubble point, relative saturation, compressibility factor of non-ideal gases, solution idealization, and solutions to non-ideal gas equations of state (like SRK) given two out of the three state variables. Just a thought.

Thanks for everything thus far.

Posted by Jarett Hibbert December 22, 2009 at 1:57 am

THE search engine of the future. But, as Andy wrote it, it would be more used, if non-US data were available, by the rest of the World.

Posted by Alain Herman December 22, 2009 at 1:58 am

Brilliant concept but please expand more outside the USA

Posted by ALAN MC AFFEE December 22, 2009 at 2:04 am

I agree. It needs to become more international and far less US oriented.

Posted by John Pretorius December 22, 2009 at 2:05 am

It would be really useful to have some non usa data for example, I live in Dorset uk, the town I live in is Christchurch. Can’t seem to find any information re this, and in particular, political makeup within the county especially as there will be a general election in uk in 2010

Olá amigos!
Quero parabenizá-los pelos magníficos avanços matemáticos.
Por favor, pergunto:
“Se a Vida só pode ser entendida através dos números”, então, que tal, criar uma nova especialização: “Matemática Espiritual”.
(Esta será a área mais consultada do seu software!!!)
Explico: nós somos inteligências eternas, cósmicas e universais, atualmente habitando o planeta Terra.
Isto implica que há todo um conhecimento a ser explorado, o conhecimento da Realidade Espiritual.
Haveria como expressar esta realidade sob forma de números?
Algumas perguntas a serem respondidas pela “Matemática Espiritual”:
a) Quantas encarnações eu já vivi até então?
b) Qual a idade do meu Espírito?
c) Quais os Planetas onde eu já habitei?
d) Quantas vezes mais reencarnarei no Planeta Terra?
e) Na próxima encarnação, irei para qual Planeta?
f) Baseado nas nossas origens cósmicas, demonstrar a incidência das raças.
g) Baseado na média do número de reencarnações dos encarnados, qual a minha média?
Amigos, talvez as perguntas possam causar algumas dúvidas, mas espero serem suficientemente instigantes para que vocês busquem as respostas.
Alguém, algum dia, dará respostas para tais e outras muitas e muitas perguntas pertinentes ao Mundo Espiritual, o qual até hoje, ainda não se pode: Pesar, Medir, etc…
É preciso transceder!
Ao trabalho senhores cientistas!
O desafio está lançado.
Muito obrigado pelo seu tempo e espaço mental.
Respeitosa e fraternalmente,
Leal – aprendiz em todas as instâncias da Vida
Pindamonhangaba-SP – Brasil
Nota: publicarei este texto-desafio no meu pequeno blog.

There are still some purely mathematical problems that I feel W.A. could help me with, but I just cannot figure out how to formulate those problems. Say that I want to minimixe the global maximum of the following function by adjusting the real constant a:

sin(x)+a*sin(3*x) , where x is from 0 to 2*pi

The answer is: a=1/6. But how can I get W.A. to compute this?

Posted by Erik Grindheim December 22, 2009 at 3:32 am

As impressive as your achievements are, you still need desperately to vastly increase Wolfram Alphas language capabilities. When users can ask questions in everyday English (or other languages) and get answers to those questions, then Wolfram Alpha will be truely unique and a joy to use.

Posted by Allen W. Ragland December 22, 2009 at 3:36 am

I need you. Keep continue to develop this project.

Posted by Hakabura December 22, 2009 at 3:46 am

I have only recently found alpha and I will be very interested to see how things develop. As yet the types of questions appear to be very limited. The mathematical capabilities may be considerable but they do not appear to know their limitations. For example I was working on orbits of objects under gravity and that shows good results for typical cases but when you get more extreme and relativistic effects have to be taken into account it does not know about this and also does not warn you that you are approaching a limitation.

Where approximations and model simplifications are used it is vital to indicate where limits are being approached or exceeded. I regularly answer science questions on and one of the most frequent misunderstandings is the belief that well established approximations are the whole truth and this leads to people taking them to absurd limits and thinking that scientists do not really understand nature.

Posted by Ian Kimber December 22, 2009 at 3:53 am

I’d echo Andy’s comment about expanding data beyond the US, especially cost of living comparisons.

Posted by Craig December 22, 2009 at 4:05 am

Beautiful work! I’m so happy to see this project growing and staying active and free.

If I would recommend one thing it would be creating a more dynamic charts feature for viewing statistical data. Ideally, it would allow you to navigate the chart by zooming in and out, and getting details about specific periods and points in the chart in real-time.

There are many open source javascript libraries that could assist you in this, such as

And there are commercial library of course, such as: (I’m not affiliated with any)

Posted by Hannes December 22, 2009 at 4:11 am

Neat ! I’m looking forward to seeing integration of more local data.

Posted by Antoine December 22, 2009 at 4:38 am

Please, consider change the color of the links for better accesibility. Great news, by the way.

Posted by ColorBlind December 22, 2009 at 4:47 am

I am convinced that you could make a significant difference by simply taking your knowledge base and doing a fine-grained breakdown of categories in outline form.

If you had more than one set of these categorical breakdowns presented on screen simultaneously you could highlight an item from each list, the result being the Boolean intersection of these selections.

Nobody has anything like this. It would be the breakthrough other search engines seem unable to conceive.

Posted by Karthik December 22, 2009 at 6:18 am

I agree with Andy, to be useful and attractive to as wide an audience as possible you have to make your data really relevant and include the real world, not just the US

Posted by Mike Egan December 22, 2009 at 6:34 am

Is the absence (so far) of information from literature and the arts because you haven’t got there yet, or because they are not computable in your terms?

Posted by GW December 22, 2009 at 6:35 am

Very impressive new features.

@ Andy Brandt: Alternative Data like shadowstats or opensecret are indeed a good idea to add. As we see with google, search engines have a big impact on what kind of information reaches the public – so including different sources is very necessary.

Posted by David Rotter December 22, 2009 at 6:55 am

I have just downloaded WA for iPhone, but haven’t had much chance to try it yet. Two questions:

1. My first query to WA, about Olympic marathon winners, failed “Could not connect to a W/A server” or something like that. I thought the point of the downloaded version was to free you from wi fi restrictions.
2. Given the ever changing nature of knowledge and your impressive programme of developments, can iPhone customers expect updates in the future?

Wishing you every success and a Merry Christmas

Featuring you again at Phi Beta Iota, the Public Intelligence Blog (

TRUE COST is the big meme you are missing, and the one that would make the most different to every discipline. Create a matrix that allows end-user inputs and group as well as moderator validation and protection–true cost in terms of water, fuel, child labor, tax avoidance, etcetera.

make it simple!

Posted by Hey December 22, 2009 at 8:32 am

“Wolfram|Alpha isn’t sure how to compute an answer from your input”

I am not too impressed. I have complained that WolframAlpha does not understand plain English English.

EnglishEnglish speakers should be catered for.

As a music teacher in Australia, I expect my students to be able to use terms like “leading note”. Even Google understands this.

WolframAlpha only understands “leading tone”.

Is WoilframAlpha bluffing?

WolframAlpha does not have a translation service like Google, but obviously needs one.

Posted by Richard Clark December 22, 2009 at 8:42 am

Wonderful source and hopefully will continue to offer unbiased intel. Great thinking for the better good!

When you type guitar chords the search result comes up blank. It should come up with all the chords. Also when you type E minor the guitar chord should come up. The way it’s setup now you have to type “E minor chord”.

I search for Delhi temperature and the results were comprehensive.

However, I next wanted to search for a different city’s temperature and I could not find the search box on the search results page.

I think it should be there …

Or, may be it was there and I was just too stupid to locate it.

May be the results page was too cluttered.

May I know if there is way to deal with massive graphs – web graphs?

Posted by R.S.Lekshmi December 22, 2009 at 9:07 am

    I recommend you check out the video about Google Maps v3 because they discuss in length displaying massive amount data on maps so it may have answers for you….

    Ideally you’d use vector based graphics but IE supports VML while other browser support SVG. However RaphaelJS is a javascript library that bridges that issue (in part at least).

    Otherwise you have to prerender the data as images and they won’t be animated or interactive (or into a movie and it won’t be interactive but it will be moving).

As an Internet Marketing Company, there is an endless opportunity for your applications on a global scale from consumers, business, government, science and research, academics etc….
I look forward to growing a global shared community network! Systems changes slowly through evolution and once in a while extremely quickly through revolution and Wolfram Alpha is going revolutionize how the aforementioned potential applications are strategically develop and integrated with your platform!
Thank You

When i want to find something like” ages between married men and women” its results don’t make me satisfied. I think that WolframAlpha should improve more about sociology not only in maths or computer science :)

Posted by ooker777 December 22, 2009 at 10:08 am

This seems to be a prime step towards efficient machine intelligence. The only part that was missing was to bind all the available knowledge together, and you guys seem to have accomplished that with WolframAplha. Now It’s just a matter of time (i.e., computational power and bigger databases) for strong AI to emerge. That’s amazing.

Posted by Carlos Azevedo December 22, 2009 at 10:12 am

Don’t listen to the “haters”, wolframalpha team! You folks rock out loud. Thank you for giving us the best the web has to offer.

Posted by Jim Koford December 22, 2009 at 10:24 am

Wonderful to hear about, yet my regular challenge raises its head again. I type in “plasma physics” and get a definition — but nothing more. I type in “plasma temperatures”, “gas plasma”, “ionized gas” and get nothing. I applaud the notion of making sure Wolfram Alpha has information relevant to the public interest (ecology, environment, employment, salaries, cost of living, and all that), but you’re missing an entire branch of physics and an entire state of matter. I’d love to compute, for example, the temperature of a certain firework as it explodes, and then relate that to whether the chemicals within have been heated to plasma or are simply burning brightly, and which additives burn the longest (and thus have more chance of landing on the audience while still hot). Pure exploration of data based on something cool and pretty.

On the other hand, the more you add, the more holes you’ll find as people search and then become frustrated when specific things they want aren’t available. Please keep tracking your “cannot find” results!

Wolfram Alpha is really advanced technology.
However,az I know, it has substantial defect-it is impossible to receive new knowledge about the nature surrounding us as this technology does not consider hierarchical transitions – occurrence of new quality when quantity of knowledges incorporated in Wolfram Alpha goes to infinity

My overall impression of Wolfie is “Good, but not great.”

Some questions are difficult to answer for any search engine, although you know the answer is out-there in cyberspace.

For example, how many New Chemical Entities now in the clinical trials listed at clinical

Not how many clinical trials total, but how many potential new drugs are represented by these thousands of trials?

To me, this seems like the kind of question Wolfram Alpha should be able to answer and should be extractable from sources like in combination with others.

    Speaking of psychrometric assessment, we would find a comprehensive psychrometric analysis of the quite variable mix of gas and volatile compounds that is expired human (and research surrogate animal(s)) breath particularly informative, especially as evidenced in breath analysis methods such as extractive electrospray ionization MS.

    An authoritative KnowledgeBase of breath molecule fingerprints characteristic of all common metabolic states and diseases, that can be accurately assessed by near real-time, non- invasive and affordable methods, can transform health assessment and care delivery.

    Regarding health care costs, a clear assessment of the role of administrative, ancillary and other not-specifically-care costs will be much more informative than tallying bottom line costs.

“Wolfram|Alpha isn’t sure how to compute an answer from your input”

Posted by Peter December 23, 2009 at 4:51 am

Nice that you keep adding data and computation features, but they are of no use if one can’t access them. When will you work on the user interface?

As an example, I’m trying to place the deepest point of earth on a map. The best query I’ve got (through too many iterations of trial/error and “Wolfram|Alpha isn’t sure how to compute an answer from your input”, ) is:
“map of the coordinates of the deepest point of the pacific ocean”

If you change it to “map of the coordinates of the deepest point of the deepest ocean”, it fails.

When will you publish some kind of API that lets us choose WHAT we want to do with our input data, instead of relying on some ambiguous-and-unknown hidden pseudo-natural processing language of a query box?

Or at least a GUI that let’s us choose what kind of visualization will be used, and which keeps track of the sub-queries (so that the “deepest ocean” query doesn’t stop working when used inside a larger one).

Good idea, clever team making eazy to get useful information for everyone-from a 5 year child to 85 year old pensioner.
Only one request : please do not think that USA is a hub of the Universe!
In your Blog I have counted word (abbreviation) “US” 9 times!
Please do not follow most of the Internet Search engines in alphabetical index of which USA stands first
There are many other countries in the world whose contribution to the mankind knowledge is much much more than that of USA’s

Posted by George December 23, 2009 at 5:44 am

    I think is so because information (news, data, statistics) in the US is accessible to the public and also because in the US more transactions are made online than many other countries and so extensive data can be collated. Also, many other countries may have data as extensive as the US but for some reason or other this is restricted and not available for the general public.

    Posted by Charles Remedios December 24, 2009 at 3:54 pm

    Dear George,
    Please do not be jealous of the US. Our political freedom of the last 230 years (maybe ending through our current political administration) made it possible for our people (all of us coming from somewhere else for economic, political or religious liberty) to do magnificent things. I would humbly suggest that if any or all other countries desire to get the maximum return from their populace, that their government interfere as little as possible with free enterprise and allow the human spirit to reach its true potential.

I am a big fan of Wolfram|Alpha. I would like to know the direction of the company. Are you guys envisioning Wolfram to be popular search engine replacing Google? Or an encyclopedia replacing Wilkipedia? If people want to use this for other than scientific research, please include local businesses and shopping results. I am forced to use Google because of that one reason. The trick is to incorporate common search and produce relevant results of what user is really looking for. For example, when I search for “iPod”, show me where I can buy it along with the technical information, reviews, pictures, online manuals, etc. Just a suggestion… You have a very solid foundation for the next level of processing information. All u need is a search that attracts common man to use the information intelligently. You guys are great!

I would like to suggest that Wolfram Alpha provide access to data buried in Master’s and PhD thesis published in the United States. I have seen many dissertations coming online; some old ones are available from ProQuest and Library of Congress. But searching these dissertations using Google is difficult and also very inefficient. We need a better way to do it. And Wolfram Alpha can contribute significantly in this area. Please note I have made the same suggestion to Google also recently.

Posted by Pacha Nambi December 23, 2009 at 8:38 pm

“fictional characters”

Don’t do this. Don’t go there (yet).
Focus on exact, measurable information first. Arts and culture is a subjective matter.
We’ve already got Wikipedia for static, loosely-curated, unstructured information.
Focus the Alpha on computable, strictly-curated, structured information.
I use Alpha when I want something I can 100% trust.
I use Alpha when I want to compute.
I use Alpha when I want to compare, because it is all-inclusive (vs. randomness of Google/Wikipedia).
Please don’t make Alpha into another Wikipedia.
Thanks. You change the world.

la operación combinada de las ecuaciones de momentos dinámicos y balance de energías cineticas para aplicar en siniestro de transito de masas similares obliga a ser muy cuidadoso en el manejo de los valores de los ángulos y las energías cineticas.
Lo resuelvo normalmente resolviendo las ecuaciones y luego usando el proceso de iteración de Excel para ajustar los valores a un todo coherente. Esto lleva tiempo y no siempre tengo la certeza de obtener valores confiables.

Dear WolramAlpha Team Members,
Merry Christmas & Happy New year to you all. Wonderful work done by you is greatly appreciated and I am thankful to you. The following suggestions may please be considered for what its worth if not already implemented.
1 Historical dates of major scientific discoveries & inventions specifically in the fields of Mathematics, Physics, Astronomy, Chemistry, Medicine and other sciences.
2 Diary of Major Astronomiclal and Celestial events going back to the past as for as possible
3 Record of Major Natural Disasters on Earth; Meteor hits(Siberia-1907), Tsunamis(Dec 24,2004), Volcano Eruptions, Major Floods, Cyclones(Katrina), Major Droughts, Record Rainfalls, Landslides, Detachment of Major Icebergs etc.
4 List of Nobel Laureates since inception and their Discoveries
5 List of World Chess Champions & Challengers from 1880. The number of World Chess Champions and/or Chess GRANDMASTERS the world has produced is less than the number of Nobel Laureates the world has seen since 1900. The scene reversed in 1990s. WolframAlpha may find out when this change occured, if interested.
6 Man made Disasters and Accidents in peace time; Shipwrecks(Titanic), Plane Crashes(US Airways A320 ditched into Hudson River, New York on January 15, 2009; 155 passengers on board had a miraculous escape, Air France A330 plunged into the Ailantic on June 1, 2009, from Rio de Janeiro to Paris when all the 228 passengers aboard met watery graves), Train head on collisions and derailments, Major Road accidents, Major Industrial Accidents(Bhopal, October 30, 1984, Nuclear Reactors out of control, Three Mile Island,USA, Chernobil, erstwhile USSR)
7 Plane Hijackings & Terrorist Attacks (9/11/2001 World Trade Center, New York, Mumbai Terror Attacks, November 26, 2008. I am not sure about your Policy in these matters, however significant they may be. Ship capture by pirates off Somali is the latest addition to these bizare events.

Ok thanks beatiful site hehehe

Posted by December 28, 2009 at 2:21 pm

In the late ’70′s, I replicated without realizing it most of Ted Nelson’s Zanadu, at least as far as the concept. One of the starting points that I thought might be a good stand-alone was something I called “The Personal Knowledge Index.” PKI was based on the idea of building an engine to connect ideas for each individual, such that a student could start recording ideas – personal or from classes, etc. – and creating hyperlinks – that would become a personal reference and mirror of ones mind. I tried to implement it on the C64, first writing my own version of a micro-Prolog in self-modifying Assembly, long before anyone knew what Prolog even was, but got interrupted by life and never finished the project.

Just a thought. People in general are faced with overwhelming amounts of data. A system with an accompanying language – perhaps a variant of LOGO – that allowed new definitions of funtioning objects on the fly to deal with ideas per se could be very valuable. The data and the computational capabilities at WA are really nice, but facilities to put data into use are also needed…

You might want to look at the site that I do for my employer – On the home page as well as most other pages, you will see the option of running a keyword search engine. This is not only THE FASTEST site search engine that I have ever seen, but it also lends itself to other uses.

When I do coding for the 2000+ page commercial site (all hand-coded by me), my techinical reference is a 2 Gig folder of code examples and tutorials with everything indexed to that same site search engine.* There is no reason that a student couldn’t use it to reference course material, or a businessman to reference business data. And, merging data sources is as simple as cut and paste. The search engine is not mine, although I tweaked it a bit, but rather came from the JavaScript Source. So, it’s freeware with the proviso that you include credit to them and internally to the original author.

*Which is particularly fortunate as my paranoid Chinese bosses suddenly about four years ago decided not to allow me any access to the internet at work. No reason. Nothing I did wrong. But once they do something, they can never admit a mistake, as that would involve losing face.
So, my only reference is my database and super search engine, which has worked so far.

I have been using wolframalpha since it was available on the web and I think it is a great great great effort for you to collect so much knowledge to support the result. Wonderful! When I use it, I just feel like living in the future! I will introduce my friends in China to try this wonderful thing!

I’ve been Following Wolfram|Alpha since it launched in May last year.
