Looks interesting.

It needs a bit of work.

I just tried entering "population Wales", and it tells me that Wales is a city in the UK with a (2004 estimated) population of 5956 people.

Wow, but you must admit thats a tough one...Tried any maths?

Tried the population of my home town, and got

Wolfram|Alpha isn't sure what to do with your input

Polite, isn't it?

Tried log(1)

log(1) = 1/(2 i pi) integral_(-(infinity i)+gamma)^(iinfinity+gamma)(Gamma(-s)^2 Gamma(1+s))/(0^s Gamma(1-s)) ds for -1<gamma<0

Well.

Wales is a village in the UK (yorkshire). It's population is 5500 according to wikipedia.

Wonder what it gives for Cetaceous.

It also doesn't know what to do with the P=NP problem.

It's obviously still under heavy development, but at this point it's a calculator with some symbolic capabilities and tidbits of factual data on some topics.

Ah, hah. That would explain that then.

Very odd that it would pick a tiny, insignificant village before a whole nation.

I wonder if it understands Cymru instead...

I tried orbital elements and found nothing.
I tried chord and found chord of a circle, not chord of a wing, not music chord.
I agree it needs some work.

I can recommend watching the introductionary video.
It is designed to give you only a specific answer to your query for information and not everything that contains your query. Refining the search does wonders. Of course it lacks a lot of information at this point (states of the UK, i.e.).

Indeed it does not give you a definition for orbital elements, but searching for orbit of ISS or orbit of GPS gives you very good results. "orbit of ISS vs. MIR" is also a very nice query to give it.

It really lacks internal hyperlinks, as shown by asking for chord. It doesn't surprise me that the search engine of the programmer of mathematica gives chord of a circle. But requesting musical chord will give an idea how to ask for specific musical chords.

Right now it is mainly giving out datasets and no general information, this will change with time though. For now the least thing it is good for is settle bets with the vs. function

I would expect that this program would be best at finding things already on the site and themes of the site. (meaning largely math) Anyways, it's not the first quick and experimental thing that Wolfram has done with his knowledge.

Ha, Google is going to compete. It seems a little unnecessary to compete, but it also seems pretty simple to implement some more mathematical functions in their search engine. (integration, differentiation, and solving for variables would be awesome)
As the article stated, Wolfram is still working on this and it is still best at sharing his own knowledge. (don't judge yet! )

 

[garyw]

try this

"where is the hubble space telescope"

impressive!

 

[RisingFury]

I like Mathematica better. You can throw an insane integral in there and wait for 5 minutes and end up with 15 line result

 

[Quick_Nick]

try this

"where is the hubble space telescope"

impressive!

Nice! Now THAT could get some use.

Not as fun or cool but try "where am I"
More fun: "where are you"

EDIT: All the examples are pretty cool. Here's the astronomy section.
EDIT2: Ok, now I'm having too much fun with this. :lol: Anyways, check this out.

Not really useful for CFD. It has some basic solutions for incompressible potential flows around airfoils and such, but these are really analytical solutions. Still a neat site, but I don't think I would pay for it.

 

[Notebook]

No I wouldn't pay for it either! I haven't anything remotely that complex, Mathcad does me well enough at the moment.

However, I think its a good idea.
If it starts to take off, having an on-line "supermarket delivery" style front-end, mixing math with your own data, and paying for delivered results.
Could be usefull.
