I just discovered the most amazing site today, and thought I'd share it with everyone else. It's the first (and so far only) computational knowledge engine, and to be honest, half an hour of playing around had me truly amazed. Basically, it's a smart type of information engine.
http://www.wolframalpha.com/For example, I started off by throwing it one of my earlier chemistry questions:
"27mg of FeSO4" and it gave me the molar amount that I was looking for, and much more. And then clicking on that molar amount (which was in millimoles) gave me
another page which contained more information including the amount in the base unit moles that I was looking for. In fact, it even knew what the chemical formula was, even though I only knew it as "Iron (II) Sulfate". And trying something later, I realized simply typing
"27mg of FeSO4 in moles" would have given exactly what I needed, that's how smart that engine is!
As nerdy as it sounds, it was a lot of fun to use, simply because of its amazing power.
So then I decided to test it with something not related to chemistry:
Searching
"cyan" gave me Hex codes and RGB codes for the color, along with other information such as complimentary colors, etc.
Making up a random quadratic equation,
"y=(x-(2/3))^2+3", it managed to convert the computer type into mathmatical form and plot it out.
Making up another random math question,
"2x+23/sqrt(16)=2", it converted it to mathmatical form, removed the square root, solved for x, and graphed the formula.
Searching the my birthday,
"may 30" returned notable events, the time difference, holidays (that I never knew existed), and sun rise + sunset of my location, fine tuned down to my city.
Searching
"canada" gave me no shortage of information from land size to unemployment percentages, to maps, to the internet code!
A search on
"omega" refered to the character, including the language and unicode number.
Making a random string of ones and zeros in hopes of being intrepid as binary,
"1010111" got me the decimal number, a number line, and some very intesting facts of it (it cannot be written as the sum of 3 squares).
Searching
"the sun", got me information on sunrise/set in my location, distance from the earth, temperature, estimated life expectancy, etc;
Searching
"google" got me the stock value, number of employees, web site address, location, annual revenue (that's a lot!), and a dozen other stuff you have to be a stock trader to understand (it does say that it's a "strong buy" though).
Searching
"michael" (my name) told me it's the 3rd most popular name but expected to rise to the number 1 spot in the USA eventually.
And of course, the crown jewel, searching for
"the answer to life, the universe, and everything" got me 42.
How "smart" that engine was surprised me... Mathmatical questions I've never seen a computer done, it performed instantly...
Have fun.
