 Sep24 awarded Autobiographer Jun10 comment 'Obvious' theorems that are actually false No good at maths or physics, but even if we take a purely mathematical cylinder, if you're stretching it as far as infinity to prove that its surface area is thus, does not the volume become infinite at exactly the same instant? Jan9 comment Stopping the “Will I need this for the test” question I find this an interesting question, since as a student I have always found mere facts (at least in highly logical subjects such as maths and science) boring and impossible to memorise. Understanding was always a much more exciting concept for me. Oct23 comment Why does the google calculator give tan 90 degrees = 1.6331779e+16? Interesting how it's still not quite the same answer. I wonder what this tells us about the architecture they use. Oct3 awarded Commentator Oct3 comment Riddle: 1 question to know if the number is 1, 2 or 3 You have to offer two options to allow each of her three choices to correspond to one of the numbers. If her number is 3 she'll say Yes because adding 3 to 0 or 1 is always greater than 2. If her number is 2 she won't know, because if yours is 0 it won't be but if it's 1 it would be. If her number is 1 then adding either 1 or 0 won't make it greater than 2. Aug15 comment Should I put number combinations like 1111111 onto my lottery ticket? I just plain don't understand this answer. To me both statements sound identical.

Yes I think it is a matter of their lexical engine is too fuzzy by default and I don't think we can change this. Dec18 asked Wolfram|Alpha Plotting multiple geometric objects Dec15 comment Newton's rate equation, determine constant and re-use My friend got an answer of 45 minutes though, using this last equation I show (the dT/dt). So I think his trick is using an approximate form of the Newton equation rather than solving for something like 15.1 as the final temperature... but I thought with the accurate k from the Newton equation I should get a similar answer to him, but his k is 0.02 when mine is 0.029... The second one is supposed to be saying the time taken to get to approximate 15 C (from 185 C) but it comes out very close to my first answer... I haven't done the same thing twice.

Dec15 comment Newton's rate equation, determine constant and re-use JohnD, I'm not sure why you've got an upvote because I don't think that helps me - can you expand what you mean by T(t).
