Transcript

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