I typically use Google for any data-gathering I need to do.

Recently, I tried out Wolfram Alpha. This thing is pretty interesting.

But I couldn't think of any use besides figuring out what the weather was like on my date of birth.

Has anyone put this site to good use?

They should've called it Wolfram Alpha Research, and then your question could've beeen "WAR: what is it good for?" –  Alistair Knock Jul 15 '09 at 15:32
    
Great one Alistair :D –  Andrea Ambu Jul 15 '09 at 15:43
    
+1 Good question for the SU knowledgebase. LOL @Alistair! –  pavsaund Jul 17 '09 at 8:43

@Alistair - but then the answer would be "Absolutely Nothing" –  Joe Schmoe Jul 19 '09 at 15:47
    
@Alistair you thought exactly what I did seeing the title :) –  Kent Fredric Jul 19 '09 at 15:53

Joel says "Why Wolfram Alpha fails" based on this Wolfram Alpha and hubristic user interfaces

i don't get it... if a new tool helps me to get my work done quicker i doubt it will fail –  Anonymous Jul 17 '09 at 9:01
    
Hadn't noticed it failing, I find it very useful. I'm thinking that the solution set it provides just isn't one that Joel needs at this time. –  Brian Knoblauch Jan 26 '10 at 12:59

I have not but I would think that it would be great for journalists, authors, documentarians or anyone else who needs to get statistical data. The fact that Wolfram Alpha tries to cite their sources is great for these folks. College students writing papers in lots of different fields I would think would use it as well.

Wolfram Alpha needs lots of organized data to be useful. This means that something like the internet is not what its meant to index.

I'm thinking about various companies that deal with lots of organized data and need a computational engine will find this useful.

I only use it for facts, plotting graphs (sin(x)) and funny words! (cosy sins - try it!)

share|improve this answer

I have used it a couple of times for unit conversion and timezone calculations, which was moderately useful... Its largely just a curiosity though.

I use it for combining colors to get hexadecimal values when writing colors in css.

for example, I need dark red: red + #000000

It does a lot of things!

I study electronic engineering and it is the coolest web tool :) Something like a web based mathematica

Few examples:

integral sin(x)*sin(x)
inverse laplace transform 1/(s+3)
plane for (1,1,1) (0,0,1) and (1,2,3)
RLC circuit 1ohm, 3nH,1pF

Or roughly analyzing my computer consume: 0.25 €/kwh * 650W * 1 month
or you can ask it what will look like the weather tomorrow (it will guess your current location)

Or even funnier (maybe not so useful) things like:
google employees/apple employees

or cheating at the hanging man game: O _ E _ F _ _ _

It's like having a "free" copy of Mathematica at hand, usable even on a netbook or on my N78 :) Don't know why you should use it but it works for me very well!

PS: You should really try to follow links to get the idea.

+1 for a great answer. Wolfram Alpha isn't for everyone, and this answer highlights just that. (would have given a +2 if i could for the hangman cheat!) –  pavsaund Jul 17 '09 at 8:41

+1 for the Hangman/Crossword solving link –  tjrobinson Jul 17 '09 at 8:42

+1 for excellent comment and examples. Now I know what to use at hangman! Bwahaha. –  EvilChookie Jul 18 '09 at 0:56

I've found it good for "How long it takes?" type questions for example

The correct answer is: To answer every question your precocious 6- 11 year old has. When he asks what the largest moon in the solar system is. Or how many gallons of water are in the pacific ocean... Wolfram should have those answers.

While I realize that not all the databases that will be in Wolfram Alpha are in there now it will they will be.

Btw the ocean question takes two queries

pacific ocean area * pacific ocean average depth

convert 1.605x10^8 mi3 to gallons

"While I realize that not all the databases that will be in Wolfram Alpha are in there now it will they will be." This sentence makes no sense. –  Adriano Varoli Piazza Jul 28 '09 at 20:40

Wolfram Alpha itself changes the question to: What are you?

And changes it to: I am a computational knowledge engine.

Chemistry. If you want to see the chemical formula for methane, you can find the state of matter at different temperatures and pressures. I use it all the time for calculating values of hydrogen storage.

It's especially useful for using systems of metric and "U.S. Customary" in the same formula without having to worry about missing a conversion. But Google can do that for you...

Here's another good blog post about the frustrations of using Wolfram|Alpha. Until they work out the user interface problems, W|A will remain a curiosity. Once they do, a user should be able to fulfill the promise of being able to synthesize new ideas by juxtaposing data in new ways.

In the mean time, I only play around with it. There's very little depth I can access without a tremendous amount of gyration.

Also, the number of errors people have found in the data and calculations is discouraging.

It's great for putting calculations into context for every day use. For example try: 100GB / 400 (users) and you will receive the result not just in GB, but also MB, CDS, DVDS etc.

to prove your geekness

I am joking :) I still have to find sometime to playing with it and searching good uses that could help me and my work

I've found it useful for calorie counting and nutritional information, given base ingredients. While about half my queries end up with "Wolfram Alpha isn't sure what to do with your input", with a little bit of tweaking and understanding the parsing engine, I'm able to get accurate counts of the foods I'm about to put into my body. For example, French Toast.

This may not answer what it is "good for," but there are lots of easter eggs to find.

share|improve this answer

the best funny ones are :

  1. do you like me? http://www.wolframalpha.com/input/?i=do+you+love+me%3F
  2. what are you? http://www.wolframalpha.com/input/?i=what+are+you%3F
  3. who created you? http://www.wolframalpha.com/input/?i=who+created+you%3F
  4. what is your favorite color? http://www.wolframalpha.com/input/?i=what+is+your+favorite+color

super funny :)

sorry sorry didn't pay attention I'll update them –  martani_net Jul 28 '09 at 20:33

I found it useful for comparisons. Such as: gdp vietnam, cambodia, which produces a series of useful statistics, and even charts the raw results:

Sure, I could compile this data myself from State Department reports, and put that into Excel, and graph it, and save the result as an image for inclusion in my report... or, I could just put that into Alpha and get the results I need in 1 click.

Also useful for learning Mathematica itself.

For example you want to know how to integrate a function in Mathematica, then you enter

integrate x y dx

on Wolfram|Alpha and click on the result to see that the corresponding Mathematica plaintext input is

Integrate[x y, x]

Suppose you want to know how to graph a list of data points in Mathematica, you could enter

graph n^2 from 1 to 10

on Wolfram|Alpha and click on the 'Mathematica form' link (in the first box) to see that

Plot[n^2, {n, 1, 10}]

is the corresponding Mathematica form.

I wish other programming languages also have this feature.
