### Introduction to Wolfram Alpha

1. 1. Wolfram Alpha (an introduction) Julie Starr | juliestarr.co.nz
2. 2. www.wolframalpha.com is a computational knowledge engine
3. 3. It doesn’t search the world wide web
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
6. 6. Imagine you’re dusting off a piano and trying to remember a chord
7. 7. Type in ‘D dominant 11th’ and Wolfram Alpha shows you the chord, notes, notation and lets you hear it
8. 8. Wolfram makes maths a doddle
9. 9. \$250 + 15% = \$287.50
10. 10. d/dx(e^(ax)) = what Wolfram says …
11. 11. … and it shows you the steps to get there
12. 12. Wolfram can help you picture what things look like by lasombraenlapared on Flickr by Oleg Alefirenko on Flickr
13. 13. Type in 49 trecedillion to get a raft of figures that describe it
14. 14. Type in ‘33g of gold’…
15. 15. … and you learn its volume, sphere radius, latent heat of fusion and energy required to melt it
16. 16. What makes orange? Ask Wolfram to add red to yellow and you’ll see. You get the rgb and hexadecimal too
17. 17. How many pages does 6,000 words fill? Wolfram says 12 and it’ll take 100 minutes to type, 22 minutes to read
18. 18. Type in ‘weather’ and a place and date and you get a snapshot of the weather that day by darren131 on Flickr
19. 19. Type in any date and you find out how many days ago it was and what time the sun rose and set
20. 20. Search for ‘fish production New Zealand’ and compare it with France (add ‘France’ after ‘New Zealand’)
21. 21. Want to know how long it takes to fly from Auckland to Wellington?
22. 22. Type ‘Auckland to Wellington’ and Wolfram will tell you, along with the distance and local time and population
23. 23. Wolfram Alpha doesn’t know as much about New Zealand as it does about other parts of the world…but it’s learning
24. 24. Type ‘Raglan’ & you get information about a coat sleeve…
25. 25. …but only a little about our small but celebrated surf beach
26. 26. It has more to say about Auckland by Light Knight on Flickr
27. 27. Wolfram can give you ‘internet users’ in Europe
28. 28. …and in New Zealand
29. 29. It can compare websites of a certain size (using Alexa) – type in the url of the two you want to compare
30. 30. In fact, you can compare any two things by entering them in the search box
31. 31. Even apples and pears
32. 32. by bootload on Flickr That’s Wolfram Alpha in a nutshell. But it can do WAY more than that
33. 33. It’s worth checking out this link for more examples of how to use Wolfram Alpha http://www07.wolframalpha.com/examples/
