@BernardMeurer, oh, man, you have the flu? Hope that gets better soon! And homework, too? Wow, I'm sorry. But anyway, arctan is the inverse of tan, I know that, but I'm not quite sure what that means in this context. I know that normally inverse is 1 over whatever number, or if it is a fraction, flipping the numerator and denominator (which is basically the same thing, because any whole number can be written as a fraction).

@heather I have an important Chemistry exam tomorrow morning :)

I hate chemistry fyi

heather

@BernardMeurer, right, because you're a computer science major (right?)

Good luck! (and sorry, because it's terrible to study for something you don't even like, and double sorry, because I mixed up your major)

Bernard Meurer

I feel like I should have gone for CS now that I look back though

Anyway, I digress

(@heather Don't worry ;))

@BernardMeurer she won't let me

@ACuriousMind > There's no continuous set of generalized position operators - not ever a position operator at all - and hence no "wavefunction".

This is a nice way of wording my long-time hate for the wavefunction approach

@EmilioPisanty, that last picture is just a trivial modification of this one, duh!

@SirCumference The reality is that, for many (most?) professionals, taking seriously the opinions of those that disagree with you is, in fact, a pretence. That is, don't take take seriously those that claim to take your opposing opinion seriously.

$\arctan$, anyone?

If anyone is interested in a trig discussion.

Can I ask you a question?

0celo7

Don't ask to ask

rob

@SirCumference Only one, and that was it.

Sir Cumference

@rob :(

rob

From here on, statements only.

"I wish you would tell me about X"

Sir Cumference

I wish you would tell me if the following is correct or not: At some time t, is the scale factor just the ratio between the proper distance of an object from us at time t and its distance now.

rob

I dunno. Cosmology isn't my strong suit.

Sir Cumference

2:30 AM

All right, thanks

btw @0celo7 can I ask you something?

Fine

@0celo7 I wish to ask you a question

Q: Previous company name is ISIS, how to list on CV?

The previous company I worked at for 6 months is named ISIS. It was founded way before the terrorist organization of course, and now it is a bad coincidence that I list ISIS as work experience on my CV. I am afraid of this name affecting my future job applications as the name ISIS is associated ...

although interestingly I'm off from LIGO's claimed event timing by 15 seoncds

despite using their recommended library to parse their time data

\o/

Although it's possible I missed something else there :P

rob

@GPhys That's potentially interesting, since the Fermi telescope detected a possible faint one-second transient in coincidence with the 2015-09 event. Most likely outcome, as you say, is that you missed something.

Q: Kinetic energy storage via superconducting loops aka LHC but with much more massive projectiles

Hi I have an idea floating around i've always wondered about.. Would it be possible to use the particle fountain concept to store kinetic energy? ie. use magnetically suspended ..uh physical magnets i guess, rather than beams... like a circular gauss rifle? I would suppose that this idea would be...
