Wolfram Alpha, the new computational knowledge engine from Wolfram Research has been getting a good run in the press this week so I decided to try it out.

It gave pretty good answers for most of the following queries. Try them out yourself.

- 2, 4, 8, 16, 32
- x x + y y < 1 && x < 0
- Sin[x] == (x + 0.5) (0.5 - x) + 0.5
- linear fit {{1.3, 2.2}, {2.1, 5.8}, {3.7, 10.2}, {4.2, 11.8},{1.3, 2.5}, {2.1, 2.8}, {3.7, 13.2}, {4.2, 11.8}}
- eigenvalues {{4,1,2,2},{2,-1,2,2},{4.1,1,2,2},{2,-1,2,2}}
- svd {{1,2},{2,4},{3,6},{4.0001,8.001}}
- google vs.yahoo
- lung cancer
- bovine tuberculosis rate New Zealand
- GDP per capita vs life expectancy
- number of moose in Canada
- infinity + 1
- infinity ^ infinity
- How long does it take to count to infinity?
