Well, an example from yesterday -- while troubleshooting an electronic circuit, I wanted to know (roughly) how long I can survive without external power, given that there is a 10uF capacitor powered at 3V.
Nothing revolutionary, but it's nice that you can just enter "10uF * 3V" into Wolfram Alpha and get the answer both in coulombs and A*s (which is what I really needed), all the while confirming what you think the relations are.
So I'd say I use it as a smart calculator that also assures me my thinking is correct.
- Florin_Andrei 15y agoThat's exactly what I use it for most of the time. Byzantine calculations using random units and it usually gets it right. Awesome.
- dmd 15y agoBut Google can do that too. Just search for "10 microfarads * 3 V in amp seconds"
- jwr 15y agoMy calculator can do that, too. But the question was what people use Alpha for, so I answered with a (simple) example.
