Who wants to learn something today?

Ask me questions about science and I'll answer them.

how do you calculate the molarity of water?

/sci/ is requesting a time-stamp with your degrees and other relevant material that will prove your qualifications.

Until then, your thread will be saged.

Thank you for your cooperation.

you cant calculate molarity with no solute

then how are people able to say that the molarity of water in pure water is 55.55M?

concentration=amount of substance/containing volume. you dont neccessarily need a solute

>molarity
is the concentration of a solute in a solution. the answer you gave is basically number density

Say I have a compact simple gauge group, does a non-trivial quantum Yang-Mills theory always exist on <span class="math"> mathbb{R}^{4} [/spoiler] that has a mass gap <span class="math"> \Delta > 0 [/spoiler]?

I'll most probably flunk out of university because I was a lazy ass . I'm studying physics and it's the only thing I'd really be interested in. What should I study if I really don't make it?

you're already making excuses for yourself. your odds aren't very good. make an effort instead of excuses

Molarity is moles per liter. A mole of water is roughly 18g one litre of water is 1000g so 18/1000=55.5

I was lazy as fuck, started learning two weeks ago, today I (most probably) fucked up on a test I had to pass, and I'm now learning for the next one, which is as I said most probably waste of time, unless it somehow occurs, that I passed todays test. I'm not making excuses, just asking if someone maybe was in a similar situaition.

im currently enrolled in an EE master, but i like semiconductor physics way more than classical E/M modelling, partly because i dont understand it that much. is this a bad thing?

yes but spergs misinterpret it and misuse the word. it also has imaginary parts

>> No.7549838

>>7549823
Not in quantum mechanics, at least it's not physical. The wavefunction contains all of the dynamical information needed to describe a quantum mechanical system, however there is not physical interpretation for it. There is an interpretation for the inner product of the wavefuction with itself, namely it represents the probability of finding an electron (or whatever) within x+dx.

How hard is engineering in reality? I hear so much about 90% of the classes dropping out within weeks.

>> No.7550466

>>7550459
it's lots of work. upper level courses can be tough, but some aren't. most are though.
>I hear so much about 90% of the classes dropping out within weeks
like 60% drop engr before the second year. theres lots of weed out classes with bullshit exam questions to add extra difficulty. by third year nobody really drops because thats what they want to do, maybe 5-10% drop out after year 3, but those numbers are probably higher for other engr majors, nuke is a pretty small program and everyone here is here for a reason. but it's definitely not easy
