Re: 1057: "Klout"

Klout kinda seems redundant for academics, since our career advancement prospects have been running on basically a Klout system for decades now.

Ah, this is much nicer than last time. Peace shall reign on these walls, unless perhaps people have really strong opinions about the strengths and weaknesses of Enchanted .

Re: 1038: "Fountain"

I love the art in the first panel. I don't know much about drawing, but that seems like it's difficult to do well.

Re: 1032: "Networking"

Could someone help me pin down what exactly beret guy/gal's character represents? Is it innocence? Spontaneity? Absurdity? Has his/her personality evolved significantly over the course of the comic? I really never know what to expect when he/she shows up, and maybe that's the point, but I feel like ...

I wonder if a large motivation for #1010 was to set this one up. In that case, I have more respect for it now

Re: Gravitational mass defect

Thanks for the response. So, to be explicit, you are saying that the answer to my first question is (1-ε)M, and the answer to my second question is that you use the full (511 keV)/c 2 ? To me, this seems contradictory. If you say that the full rest mass energy is conserved for every proton and elect...

Gravitational mass defect

This question concerns accretion onto super-massive black holes. When material of rest mass M falls from infinity onto a black hole accretion disk, it gets heated and then emits so much light that the energy radiated away can measure up to about 30% or so of M c^2 (I can point to references should t...

Re: Some questions about the volume of the n-ball.

Here's a fun fact, first pointed out to me in a column by Martin Gardner: if you sum the volumes of all the unit balls in spaces of even dimension, you get [math]e^\pi[/math] I think that's kind of a beautiful variation on the Euler formula for exponentiating imaginary numbers.

Re: Expectation of a function of random variables

I know that that the distribution of \phi_1 - \phi2 is triangular with a maximum at 0. That would mean that the most likely values of the final function are close to 1. It's the next step that has been tripping me up, which I think will involve playing with inverse cosines - I think I might be doing...

Expectation of a function of random variables

If [imath]\phi_1[/imath] and [imath]\phi_2[/imath] are both uniformly distributed random variables between [imath]-\pi[/imath] and [imath]\pi[/imath], then what is the expectation of [imath]\cos(\phi_1 - \phi_2)[/imath] ?

Aside from the numerical answer, some insight into the analytic solution would be helpful for a problem that I am working on.

Re: INTRO THREAD THE THIRD

Hi,
I'm from the US, and I'm a college student majoring in physics and math. This comic has been an important part of my life for at least a year now, and I have put off registering for far too long. I'm looking forward to talking to you!
