A trip to the doctor’s office can sometimes leave patients with more questions than answers, specifically if their doctor has requested they undergo medical tests. Wolfram|Alpha is a helpful reference for understanding what the tests measure and how to interpret the results. Wolfram|Alpha allows you to query information on a specific medical test or a panel of tests, compare tests and results for patients with specific characteristics, compute your estimated risk for heart disease, and find the diagnosis corresponding to an ICD-9 code. Wolfram|Alpha can take into account specific patient characteristics like gender, age, smoker, non-smoker, pregnant, diabetic, obese, and underweight. Wolfram|Alpha can give you a snapshot of available data that might help you understand how your results compare to others’. (Wolfram|Alpha does not give any advice, medical or otherwise.)
First we will demonstrate how you can use Wolfram|Alpha to learn more about a specific type of test your doctor has ordered. By entering the name of the test into Wolfram|Alpha, such as “CBC”, we can learn what the test measures. In this case, the test measures the number of cells commonly found in a blood sample, such as red blood cells and platelets.

Wolfram|Alpha contains a wealth of astronomy data on many areas of our universe, such as objects within our solar system and in the deep sky, constellations, and computational astronomy, making it a handy resource for astronomers, students, and hobbyists. Some of the most intriguing space activity takes place right here at home, inside of our own solar system. Wolfram|Alpha makes computations and explores properties and locations for objects and events in our solar system, such as the sun, planets, planetary moons, minor planets, comets, eclipses, meteor showers, sunrise and sunset, and solstices and equinoxes. You can query any one of these objects or phenomena, and learn information such as their position in the sky relative to your location, size, or distance; their next occurrence; and much more.
Wolfram|Alpha automatically assumes your geographic location based on your IP address, which is handy when querying for the time and location of an upcoming sky event. For instance, a quick “lunar eclipse” query in Wolfram|Alpha tells us that, for our location in Champaign, Illinois, the next one will occur on August 5, 2009 at 7:38pm U.S. Central Daylight Time and will be penumbral, which means the moon will enter the Earth’s penumbra (the outer part of its shadow), resulting in an apparent darkening of the moon. A penumbral eclipse is often hard to see because the penumbra isn’t very dark.

Wolfram|Alpha is a great resource for writers. It has an enormous words and linguistics database that writers can use for such things as word definitions, origins, synonyms, hyphenation, and Soundex lookups.
Type “word contest”, and Wolfram|Alpha will retrieve the word data for the English word “contest”. The results tell you many definitions of the word, that its first known recorded use was in 1603, that it rhymes with “conquest”, and a wealth of other data on just that word.

We are continuing to demonstrate ways you can use Wolfram|Alpha’s nutrition and wellness data, with helpful input tips and examples. In this example we are talking about how to use Wolfram|Alpha to make smart food choices. A variety of nutritional factors may be of importance depending on your dietary needs and wellness goals, which is why Wolfram|Alpha goes further than just providing the total number of calories in a food item.
Whether you are concerned about monitoring your total fat, cholesterol, sodium, sugar, carbohydrates, or other nutrients, Wolfram|Alpha can provide you with this information for an individual food item, a meal, or a comprehensive calculation of your daily diet. In this post we’ll demonstrate how to calculate and compare the nutritional values of two food items. More »

Many of our world’s advancements can be attributed to the evolution of communication mediums and styles. Today we can tweet a message in 140 characters or less around the world in a matter of seconds. But long before the days of the radio, telephone, the fax machine, and email there was the original text message—Morse code. And Wolfram|Alpha can translate a string of characters to and from Morse code.
Morse code was introduced to the world over 160 years ago, when Samuel Morse and Alfred Vail invented a telegraph that when triggered by electrical pulses made indentions in a paper tape with a stylus. They also developed a code of short dots and long dashes to represent letters, numbers, and special characters, allowing messages to be sent via those indentions. The sounds produced when the telegraph processed the electrical pulses became so familiar that adept users could translate the code by sounds, and the code would eventually be adapted for broadcast across the radio airwaves. This system would go on to become a major form of international communication, especially for those working and traveling in the air or out at sea.

Does today’s crossword have you puzzled? You could continue to fret, and fight the urge to check the full solution, or you could consult Wolfram|Alpha, which has the tools you need to solve the sneakiest constructions. Wolfram|Alpha can find words matching a pattern, words with specific beginnings and endings, and provide word definitions.

We have been highlighting ways that Wolfram|Alpha can be a useful tool in your everyday life, and we believe you will find our salary and wage data helpful in navigating your decisions in today’s job market. A lot of people are searching for full-time employment, relocating, exploring going back to school to change professions, or considering taking on multiple jobs. Many factors play into these decisions, and Wolfram|Alpha’s U.S. occupational salary data, and salary computations for local currencies, help you make informed choices.
Perhaps you are considering changing professions. In addition to supplying data on specific occupations, Wolfram|Alpha can compare U.S. occupational information for multiple jobs, including the median salary, the number of people employed at those jobs, and more. For example, here is the comparative information for a registered nurse, an elementary school teacher, and an accountant: More »

Wolfram|Alpha introduces many new methods for understanding linguistic inputs. Those methods allow you and others around the world to ask it questions in natural ways. In this video, a developer working on Wolfram|Alpha’s linguistics shares a bit about her role in building and improving the system’s understanding to help you get the answers you’re looking for.

We have spent some time on this blog talking about ways Wolfram|Alpha‘s nutrition and wellness data can be useful tools in your everyday life, such as by computing the nutritional value of your favorite recipe and identifying a healthy body weight. Some of you have since asked how you can use Wolfram|Alpha to understand your body’s caloric needs to maintain a healthy body. With all of the talk surrounding the latest fad diets and nutrition programs, information about our bodies’ basic needs often gets lost in the noise.
You can estimate your body’s daily caloric needs by computing your basal metabolic rate (BMR) within Wolfram|Alpha. Your BMR is the estimated number of calories (energy) your body expends when at complete rest—in other words, your daily caloric needs just to operate your vital organs, nervous system, muscles, and skin. BMR varies based on your age, gender, height, and weight, and needs to be recalculated whenever one of these factors changes. As your physical activity increases through routine movements, and exercise, the number of calories your body needs increases. More »

Baseball is the great American pastime. We’re at the midpoint of the Major League Baseball season, and fans are gearing up for the 2009 Major League Baseball All-Star Game, which will be played on Tuesday, July 14, 2009 in Saint Louis, Missouri. For baseball fans, this “Midsummer Classic” embodies much of what there is to love about baseball: a night at the park, hot dogs and Cracker Jacks, and top players from American and National League teams all on one diamond. But what we at Wolfram|Alpha love about baseball are all of the fast statistics that can be quickly computed and returned as easy-to-read graphs.
Wolfram|Alpha contains statistics and history for Major League Baseball teams’ wins, losses, pitching and batting histories, and more, from 1960–2008. This information allows you to easily compute statistics for a single season, or graph a visual history over decades. More »
