is a computational knowledge engine

It computes answers from

Imagine you’re dusting off a piano and trying to 
remember a chord
Type in ‘D dominant 11th’ and Wolfram Alpha shows you 
the chord, notes, notation and lets you hear it
Wolfram makes maths a doddle
$250 + 15% = $287.50
d/dx(e^(ax)) = what Wolfram says …

Type in 49 trecedillion to get a raft of figures that describe it
Type in ‘33g of gold’…
… and you learn its volume, sphere radius, latent heat of 
fusion and energy required to melt it
What makes orange? Ask Wolfram to add red to yellow 
and you’ll see. You get the rgb and hexadecimal too
How many pages does 6,000 words fill? Wolfram says 12 
and it’ll take 100 minutes to type, 22 minutes to read
Type in ‘weather’ and a place and date and you get a 
snapshot of the weather that day

Type in any date and you find out how many days ago it 
was and what time the sun rose and set
Search for ‘fish production New Zealand’ and compare it 
with France (add ‘France’ after ‘New Zealand’)
Want to know how long it takes to fly from Auckland to 
Wellington?
Type ‘Auckland to Wellington’ and Wolfram will tell you, 
along with the distance and local time and population
Wolfram Alpha doesn’t know as much about 
New Zealand as it does about other parts of 
the world…but it’s learning
Type ‘Raglan’ & you get information about a coat 
sleeve…
…but only a little about our small but celebrated surf 
beach
It has more to say about Auckland 
by Light Knight on Flickr
Wolfram can give you ‘internet users’ in Europe
…and in New Zealand
It can compare websites of a certain size (using Alexa) – 
type in the url of the two you want to compare
In fact, you can compare any two things 
by entering them in the search box
Even apples and pears

That’s Wolfram Alpha in a nutshell. But it can do WAY 
more than that
It’s worth checking out this link for more examples of how 
to use Wolfram Alpha

  4. 4. It computes answers from its own knowledge base
  5. 5. It’s great when you want to add, subtract, multiply, square, compare, hear a chord, see a colour, find out about fish production in France, remember past weather, imagine a very big number and a host of other interesting things
