I got a question for anybody who may be in the know...

I'm currently doing a joint major in Computer Science and Pure Math with the goal of doing a masters in either math or CS with a focus on cryptography; I'm also considering (though not at the moment due to my already insane workload) of minoring, or adding another major in Physics for the purpose of studying Quantum Computing (wrt quantum cryptography)...

Shog9

...and you want to know where to score some crack, eh?

agent154

Would a minor be sufficient since it's only an extention of my studies in CS and Math, or would a major be recommended? Also, if a minor is sufficient, what would be the general topics (aside from mandatory courses) that I should look into?

dmckee

It sounds like you want to master quantum mechanics. Once you have the basics you can push as hard as you want or need in that direction.

So, take the lower division sequence and math methods if offered and QM.

Why bother with anything else if physics is not your first love and you are overloaded already?

agent154

I'm only thinking of going into physics due to its relationship to quantum computing... Definitely not my main career choice. But I suppose with that said, a minor would be more than sufficient, since I'd only be doing this mostly out of interest and as an added bonus to my current academic path. What would the prerequisites be to learning about the subject?

So Quantum Mechanics is really the thing I want to look into? I missed your message until jus tnow

Thanks. I'll ask my school about that and see what's needed to get to that point sometime in the future

@agent154 for the actual experimental design of quantum computing devices, you'd need to study up to intro quantum mechanics and then some specialized condensed matter/AMO material after that (probably offered as elective classes).

But for some areas of quantum algorithms, you could probably get by with barely any physics. A lot of it is just linear algebra.

Still, learning up to intro QM will definitely be helpful if you want to get into quantum computing.

And it's kind of necessary for quantum cryptography, which is really more of a (quantum) hardware key exchange protocol than an actual algorithm.

03:52

@agent154 You're in luck - the physics behind quantum computing is specific enough you shouldn't have to minor in physics to get it

ManishEarth

mornin'

user54412

in a lot of ways, it's the nicest part of quantum mechanics - the vector spaces tend to be finite dimensional, there's no ad hoc "let's throw away this infinity", etc.

agent154

Well, I'm doing fairly well in my Linear Algebra courses, so it's good to know that I'll make use of that

But I must be going now.. I'll stay in the channel so I can catch any delayed messages. Thanks for the input.

@CrazyBuddy so did you tweet your thoughts about space exploration the other day?

user54412

@Shog9 LOL I should have known

Crazy Buddy

@ChrisWhite Nah... I'm not even at home..!!! (let alone twitter) I just shared it :/

My vacation starts only from today :)

And I'm trying to synchronize myself with SE (didn't participate much for the last two days)

Two days -- I started out from home at 7:30, reached back only at night 8:30 (12 hrs in colg. alone) :/

@ManishEarth why was that site not around when I traveled to Asia???

Crazy Buddy

Oh... Did you???

user54412

@CrazyBuddy after graduating college - it's kind of a western tradition to take an extended travel-somewhere-remote-and-interesting vacation during/after college

user54412

it's very popular in Europe, somewhat popular in the US as far as I can tell

Crazy Buddy

Well, where did you go? (India? :P)

user54412

just east Asia that time - where Japan and China really confused me with their toilet practices

Crazy Buddy

04:10

Hah... :D

@Shog9: I'm still wondering how you guys write so well? Would that power come to me, my blog will be a blockbuster hit (and I can become a rep. generator here) :D

user54412

I find it hilarious that I can get the same exact bottle of Coke anywhere on the planet, and I can converse in English in any town I ever find myself, but this globalized world still has such different toilet practices

Crazy Buddy

Maybe I should start reading posts of specific user profiles in MSO too...

tpg2114

@ChrisWhite But the bottle of Coke isn't the same, it does taste different. It's close, but different.

So are the toilets. You kinda know what to do cause it's close. But you're just not quite sure it's the same

Crazy Buddy

@tpg2114 taste different? o_O

@tpg2114: And, congrats on your long-awaited 3k :P

user54412

hmm, as someone who doesn't like carbonated drinks, I guess I haven't sampled them enough, but it does make sense they'd be somewhat different

user54412

04:20

@tpg2114 Yes indeed congrats - may I retire from close-voting now? :P

tpg2114

@ChrisWhite No, cause then there would only be 3 close votes instead of 4 :P

@CrazyBuddy And thank you, I've been keeping my queue clear ;)

Crazy Buddy

Finished your 20 threshold? :O

(well, you should've seen 50 or 60 posts in the queue... No??)

tpg2114

It was only like 13

ManishEarth

@tpg2114 ooh, yay, better flag more things with my sock :P

Crazy Buddy

At least, that's what happened to me... (I had 52 posts or something at the start)

@ManishEarth: Emilio asked for 3k+ active reviewers in that meta post... Right?

ManishEarth

04:23

yep

Crazy Buddy

Instead of writing query and all, shall we put a post indicating who & who...??

(well, we know most of the active fellas)

ManishEarth

From here? Yes, that would work, though a more grainy bit of data would be nicer

Crazy Buddy

@ManishEarth I mean, (for now) we can write out a temporary post :D

(Not much useful... Eh??)

ManishEarth

temporary you mean. temporal means time

Crazy Buddy

Oops...

ManishEarth

04:27

@ChrisWhite any plans on posting on any of those recent physicsmeta posts?

I was hoping you may have some tips to improve Phy.SE experience

(and possibly some ideas to improve net phy.se experience on the other thread)

user54412

yeah yeah - when i get around to it :P

user54412

still learning all sorts of fascinating things about toilets

tpg2114

The age-old question... do I go to sleep now and try to get up in time to write up my homework assignment in the morning, or do I write it now and sleep in...

ManishEarth

@ChrisWhite hahaha

@tpg2114 either way it won't be completed

tpg2114

Historically I tend to wake up at the same time regardless of when I go to sleep... and it isn't early

Crazy Buddy

04:31

@ChrisWhite Astro grad learning about toilets... -- Nice -_-

ManishEarth

@tpg2114 life of a grad student. I have to wake up early. Though, like I mentioned before, my vacation sleep schedule is very twisted.

Crazy Buddy

@tpg2114 As a Phys.SE (and 3k+) user, you shouldn't have the habit of sleeping -- watch out for homeworks & trolls... :)

tpg2114

@CrazyBuddy Trust me, I don't. I only got about 2 hours of sleep last night

Crazy Buddy

That's great :)

Q: What are the relative strengths of TikZ and Asymptote?

I want to compare TikZ and Asymptote for their abilities in 2D & 3D functional plot and other general purpose, simple drawings. What are the strong aspects of TikZ over Asymptote?

@ChrisWhite Silly rabbit, TikZ is for kids!

@dmckee that's LaTeX for you

Q: What software programs are used to draw physics diagrams, and what are their relative merits?

People undoubtedly use a variety of programs to draw diagrams for physics, but I am not familiar with many of them. I usually hand-draw things in GIMP. GIMP is powerful in some regards, but it's time consuming to do things like draw circles or arrows because I make them from more primitive tool...

software

Shog9

@CrazyBuddy heh; I don't think I'm a particularly good writer, although there are certainly good writers working at SE. Most of what I post is stuff I've written a dozen different ways in a hundred different posts over the years, so it becomes just a matter of trying to pull in what's relevant.

@ChrisWhite best part of moving to the southwest was being able to get Mexican Coke any time I want it.

Crazy Buddy

@ChrisWhite What the?? You dare point me with a 25k+ viewed Phys.SE post..!!! (thinking that I haven't seen it yet??) :P

ManishEarth

@CrazyBuddy Learn LaTeX! Submit all your assignments in TeX and get zeroes because the professors don't like printed assignments! Never touch Word again. etc etc

OK, never yet gotten a zero for submitting a printed assignment, but I know where not to submit one

Crazy Buddy

@ManishEarth Duh... I can hopefully bet you that none in my colg. actually know "what's latex" -_-

tpg2114

@ManishEarth Get zeros? Really? I turn in all my assignments written in TeX cause the graders love it

ManishEarth

04:47

@CrazyBuddy It's a college. They better.

tpg2114

No deciphering handwriting, trying to follow arrows when I made a mistake and want to skip sections...

ManishEarth

@tpg2114 Some departments/professors are very paranoid about copying

tpg2114

That's why this homework takes forever to "finish." I did it on paper in a few hours, now I have to spend the same amount of time translating it

Crazy Buddy

@Shog9 Now, all I have to do is rob these stuff from your profile :D

user54412

I agree with @tpg2114 - graders loved my tex'd homework, and I loved grading it that way

ManishEarth

04:49

Last sem we had 26 different papers for each quiz/midsem/endsem in our math courses. All labelled differently (in one they labelled them alphabetically with the names of various mathematicians&physicists)

The elec department is especially paranoid, because the elec students this year copy a lot and their department is the one that gives out the most assignments. So...they like handwritten stuff

@ChrisWhite thought so too

@tpg2114 If/when I do it on scratch paper I do it in such an unorganized manner that no grader would ever see what's going on

tpg2114

This is 12 handwritten pages, all math, for 2 problems

ManishEarth

@tpg2114 All math? I would do it in Mathematica and copy as TeX :>

tpg2114

I'm very happy to be using the extended Hamilton's principle so I don't need to deal with figuring out free-body diagrams and boundary conditions anymore

Crazy Buddy

@ManishEarth I'm no good even in Mathematica :/

tpg2114

@ManishEarth That would take me a lot longer actually...

Crazy Buddy

04:55

Maybe I should be creative next time, and fool my professors with MathGen :P

ManishEarth

@tpg2114 Ah. I'm pretty good with the MMA shortcuts and functions so normal algebra is easy to do and subsequently TeXify. Ditto for manipulating DEs. But you probably have some advanced math.

tpg2114

@ManishEarth Not all that advanced, it's just solving an ODE. But it's deriving the ODE that takes up paper

Vibrations in a beam with various things attached to the ends of it

ManishEarth

@tpg2114 Ah. But that's just algebra and substitution, no?

tpg2114

That's the beauty of engineering... the math really isn't all that complicated

Pretty much -- lots of integration by parts, algebra

Trig identities

Crazy Buddy

@tpg2114 You don't speak about engineering to us..!!!! :P

tpg2114

05:02

Is there a way to see a "correct" vote rate on reopen/close/recommend deletion votes?

ManishEarth

@tpg2114 Nope. If review ever comes to SEDE then yes

Well, you could use your votes tab, filter to close votes, and then look at the titles

But the votes tab is private to you

tpg2114

Yeah, I was looking through the reviews by hand on each question

And seeing how others voted relative to me

ManishEarth

ah

tpg2114

It's interesting that my votes run opposite the same people on the limited samples so far

For both reopen and close

ManishEarth

with some AJAX+jQuery you probably could gather all that data quickly

@tpg2114 that might indicate that there are some policies we aren't clear about. Possibly.

tpg2114

05:06

Not when you factor in the amount of time it would take me to learn AJAX and jQuery

I actually oppose @ChrisWhite more than I expected. I guess we can't be friends.

ManishEarth

@tpg2114 heh. jQuery does ajax for you, and it's not that hard. I'll try and whip up something

hahaha

tpg2114

I know neither, I've never come across either of them actually

ManishEarth

It may be good to sit and discuss controversial (with opposing votes) closes from time to time

@tpg2114 Know javascript?

Crazy Buddy

@ManishEarth Pick me..!! Teach me..!!! :P

Nope

@ManishEarth We had access to an IBM massively parallel database system and loaded up a simulation with terabytes of data. I think we had 100 TB of data in the tables

Something like 500 million cells

And I was able to compute the vorticity at each cell in 30 seconds with that statement

ManishEarth

@tpg2114 nice

user54412

it's a good thing I'm only here another few years - too much time spent next to the Institute for Advanced Study makes you troll/interrogate anyone speaking about anything scientific

user54412

@tpg2114 that's cool and yet terrible

tpg2114

We probably could have gotten it to go way faster, but the huge database clusters are designed for mission-critical things like banking where it has a crazy amount of redundancy built in so it has all sorts of consistency checks we don't need

We don't care if our vorticity calculation gets interrupted... but they care if a bank loses a transaction

user54412

btw, were you the one using air force computing clusters?

ManishEarth

DoD I think

tpg2114

Yeah, I have access to AFRL machines

AFRL, ONR, NAVO, ERDC are all HPC centers under the DoD :)

There's some more, but those are the ones I have access to. Oh, and ARL

ManishEarth

@tpg2114 Why not modify some of the open source SQL.cluster computing variants and remove the useless bits?

Or is that me not realizing how hard that would be? :P

tpg2114

@ManishEarth Because we were working with IBM directly on their clusters. We talked about decommissioning one of our clusters and putting MySQL on it

But we (meaning I) lost interest in working on that project and convinced my boss it is ridiculous

tpg2114

@ChrisWhite Failed? Maybe we really can't be friends ;)

All of the HPC machines at the DoD require the lowest level of clearance, the "Person of Trust" level.

All the unclassified machines I should say

Befunge is a stack-based, reflective, esoteric programming language. It differs from conventional languages in that programs are arranged on a two-dimensional grid. "Arrow" instructions direct the control flow to the left, right, up or down, and loops are constructed by sending the control flow in a cycle. It has been described as "a cross between Forth and Lemmings." History The language was originally created by Chris Pressey in 1993 as an attempt to devise a language which is as hard to compile as possible — note that the p command allows for self-modifying code.

How could I be as stupid as to not realise that? Indeed, popular-level, and low-level questions are what fuel your SEO.

Higher the temperature the higher the kinetic energy atoms has. However, i learned that light interacts with electron. So how interaction with electrons translate into increase kinetic energy (movements) of atoms. btw, what does happen when light hits protons and neutrons.

@jinawee You don't need to ask if you should flag a question :P Just flag away, usually. If the flag gets declined, that will indicate that you shouldn't.

@DImension10AbhimanyuPS SE strongly emphasizes question quality and avoiding low-level question on any new beta site they start.

ManishEarth

08:35

@jinawee custom flag usually works. Also, here's a trick very few know:

@jinawee When you flag as off topic (not for migration), the exact sub reason is not really recorded (well, it is, but not visible to eve moderators). So if you think a question is off topic but aren't sure why, just flag it as any off topic subreason like homework and it will work.

jinawee

@ManishEarth Thanks

Pranav Hosangadi

@ManishEarth why does the subreason exist then? Just to make sure you don't go flagging questions willy nilly because it's so easy?

ManishEarth

@PranavHosangadi Well, it does exist for closing, btw. Just not for flagging

Because the subreasons teach new flaggers

Pranav Hosangadi

Ah, I see

ManishEarth

@PranavHosangadi The subreasons are pretty specific, they give a better outline of what is and isn't allowed. A new user may have a fuzzy idea of this, but can be more sure about flagging if he knows what is off topic and what isn't.

I did propose a change to it though

Related: No custom off topic message when flagging on SO I recently noticed something: The off topic subreason chosen by flaggers doesn't make any difference at all. Specifically, the subreason chosen is not shown to close voters. Besides, as the "other" reason is unavailable, a lot of case...

A: As a user of Physics.SE, how do I make my own experience smoother and more enjoyable?

Level up your communication ninja powers Make sure your questions, answers and comments are clear, understandable by the audience and on-topic. Use proper English. Be reasonably polite in tone (as you would be with a professor you like). Never fight with other people, or discuss their intention...

@ManishEarth ^^^

ManishEarth

thanks

UV-D

nice @Sklivvz!

ManishEarth

@UV-D Read the post, it says no hissing and spitting

UV-D

@Sklivvz Nice "bunching-up" Sklivvz... ;-)

Sklivvz

Thanks. I am somewhat suspicious that it will not help the people it should help, but...

UV-D

@Sklivvz at least you've tried

Crazy Buddy

@Sklivvz Nah, it's fine. It's simple. It says almost everything it should.

Good work :)

Seems like you're back into our meta :P

@Sklivvz I'll happily confirm that in 1 hour.

Actually, no.

Because it will involve me posting something somewhere other than my own posts.

UV-D

um... what?

by the way, to clarify, I am referring to the physics meta

@DImension10AbhimanyuPS Btw, you may be interested in looking at tea.mathoverflow.net/discussion/1512/…. I saw some of your recent TRF posts, and no, MO is strict towards both cranks and rude users, no matter how smart.

Also, we don't consider anyone who doesn't like the model as cranks. The model has changed a lot due to input and experiences, if SE didn't like disagreement then that would never have happened. We have never called any of you people cranks, and don't intend to do so. Your input is useful. Just that the same input presented over and over again ... isn't.

... I find that quite hypocritical coming from someone who regularly labels some users here as trolls. We don't call you cranks. Don't insult the time they've spent here by calling them trolls.

@ManishEarth I am quite shocked at the replies on tea.MO, but I don't think they've applied such things in practivce. At least I've seen strong criticism there.

Anonymous

@ManishEarth Well, the comments there that I have linked to definitely indicated that SE does.

Anonymous

@ManishEarth Well, trolls spend a lot of time, too.

on trolling.

@DImension10AbhimanyuPS sigh it's not that they've spent time, it's that they've spent a lot of time here with good intentions.

@DImension10AbhimanyuPS Criticism is one thing, an abrasive attitude is another. I've seen the former, not the latter, on MO. I did spend a lot of time on the site to help them fit into their SE 2.0 shoes, and it seemed a pleasant place.

@DImension10AbhimanyuPS What the comments on MSO indicate is that SE is tired of users beating the same old dead horse.

@Qmechanic hahaha I didn't even realize that

Crazy Buddy

Wait... I didn't know that we had a Hissatron...!!! (How did I go blind?) :/

ManishEarth

@CrazyBuddy it was here only for an hour

I brought it in because aufkag mentioned that Kit was using something similar

Anonymous

@ManishEarth I don't want to reply to any of that. I've replied to that enough times everywhere.

Crazy Buddy

@ManishEarth ah...

@DImension10AbhimanyuPS Actually, he must tell that to you ;-)

ManishEarth

So have I. Let's drop it

Wait, so I'll be stuck at 3 rep for ever, right?
