Stephen Wolfram, the creator of Wolfram|Alpha, just wrote a great blog post about how Wolfram|Alpha is “on average giving complete, successful responses to more than 90% of the queries entered on its website”. Along the way we saw some great examples of “artificial stupidity: places where Wolfram|Alpha gets the wrong idea, and applies its version of ‘artificial intelligence’ to go off in what seems to us humans as a stupid direction.”:
Explore this week's solar flares with Wolfram|Alpha
At about 6pm CST on March 6, there was a very powerful X 5.4 solar flare. This triggered a coronal mass ejection (CME). Indications were that the CME wasn’t squarely directed at Earth, but that a strong glancing blow to the Earth’s magnetosphere was possible. Here’s the data in Wolfram|Alpha for the flare:
This definitive app for linear algebra—from the world leader in math software—will help you solve complex problems on the fly. The Wolfram Linear Algebra Course Assistant covers a wide variety of topics, including solving an equation or a system of equations, adding or subtracting any two vectors, finding the cross product or dot product of two vectors, and computing linear transformations.
