I … did it? The first bus of the day will leave in 25 minutes and I'm so taking it. (Too lazy to cycle)

Sir Cumference

02:57

You know what I saw last week?

Light.

In fact, no one has ever seen anything other than light.

user116211

@SirCumference whhhat?

Sir Cumference

True

Did I blow your mind or something?

user116211

Okay, elaborate.

Sir Cumference

You can never see your feet as they are. You can see them as they were a few microseconds ago, but light still took time to get to your eyes

So you see your feet in the past

Ok man, have you ever looked at distant objects in the night sky?

user116211

03:12

sorry, my shift button is not working

user116211

@SirCumference yeh, it's true but how is it related to the above comment?

Sir Cumference

Well, for example, we never truly see the Sun

We only see the light it produces

So it appears to be 8 minutes 19 seconds younger than it really is

user116211

Well, even the time-varying electric and magnetic fields that are the solutions of Maxwell's equations are time-retarded.

user116211

03:15

Take, for example, Jefimenko's equations.

user116211

This retarded time-dependence implies the validity of causality.

user116211

Causality however doesn't mean the cause must happen at past.

user116211

Force and acceleration are present at the same time, although the former is the cause of the later; then how can they follow causality?

Sir Cumference

Huh...

Never considered that

user116211

Well, then there is another rule which states that if the causal relations are used in the definition, then causality is still maintained.

user116211

03:21

Which is what happened in the second law; so it still follows causality.

user116211

How amazing are they, isn't it?

Sir Cumference

Anyone know GR and QM here?

@TIPS Got the mail but didn't reply. Was it nice?

Yeah

The mug rocks

I'm even considering not using it.

Mithoron

@TIPS Hmm, thought it would be uncomfortable in practice

TIPS

@Mithoron How uncomfy?

Mithoron

11:11

Because of shape

Well Nah.

I just think I wouldn't drink anything in it so I'd never have to wash it.

I might make it a pencil case thing holder thingy though.

Q: receiving milk for working in harmful environment

I just got a job in a chemical/biological lab (Post-Soviet Country). Chemists here receive milk for "harmfulness of the work",i .e. their work involves working with all kind of substances/reactives. (I'm not a chemist I do their analysis). The tradition of receiving 0.5 litre of milk a day comes ...

Haha :)

@Mithoron Chemists are toddlers in disguise.

Are their labs different that made OP to mention that?

ah! got that! Soviet tradition!!

Damn commies ;((

@MAFIA36790 XD

@Mithoron the Soviets also used vodka against radiation sickness

@Loong That's why they got to the moon first

@Loong How could vodka help them O.O

Mithoron

11:20

@Loong Mass Lugol usage after Chernobyl probably didn't make much more good

Loong

@MAFIA36790 it might help against the symptoms ;-)

user116211

BTW, @Loong had I asked you which university in Germany provide course in English?

Loong

@Mithoron yeah, that was done unprofessionally

user116211

Well, the main criteria for being eligible to take admission entrance exam in Germany is to know German :(

Loong

@Mithoron btw, I wrote most of the German Wikipedia article on iodine prophylaxis including some useful numbers.

@MAFIA36790 yes, you talked about that.

@MAFIA36790 even for the purely English courses?

user116211

@Loong Well, it seems so.

Abitur

Abitur (Latin: "one who is going to go away", "a journey away is made", future active participle of abire) is a designation used in Germany, Finland, Lithuania, and Estonia for final exams that pupils take at the end of their secondary education, usually after twelve or thirteen years of schooling (see also for Germany Abitur after twelve years). Abitur is a matriculation examination and can be compared to A-level, Matura or the International Baccalaureate Diploma, which are all ranked as EQF level 4. == In Germany == === Overview === The Zeugnis der Allgemeinen Hochschulreife ("certifi...

The Oxbridge seems to be quite good in their administration and policy in taking foreign students.

user116211

And one good feature of English system is:

user116211

There is no major-minor culture

Loong

@MAFIA36790 That's good. I don't understand the American system.

user116211

You want to study Physics? Then choose Physics; have a BSc course in 3 years; no other additional subject is required to be taken; however, you can take classes and attend lectures of other courses too.

user116211

@Loong Unfortunately many countries including India also follow that.

user116211

11:33

This one is ridiculous:

user116211

We have a dual BS-MS degree; for first two years, we have to study:

user116211

Physics, Mathematics, Chemistry, Biology, Earth Science.

user116211

This is insane.

Loong

:-(

so you would try to study everything a bit, but nothing in a proper way

user116211

I like the English system but their expenses are far more than any Ivy college.

user116211

11:36

@Loong Total nonsense; what should I do with Biology? Rubbish ;(

Sir Cumference

13:42

Hey, can anyone tell me if this statement is correct?

"Protons and electrons will not always combine; electron capture only happens under high enough energies. That's why neutron stars form when the mass (and energy) of a white dwarf goes beyond a certain point."

Mithoron

16:07

@SirCumference Pressure is most important in creation of neutronium. It just happens to correlate with mass and temperature in case of stars.

TIPS

@SirCumference It is AFAIK

Mithoron

@TIPS Synchronization :D

Sir Cumference

@Mithoron Neutronium is a sci-fi term

Mithoron

@SirCumference neutron-degenerate matter if you prefer

Sir Cumference

Yeah, pressure is important, but it's the energy that allows for electron capture, right?

Loong

@SirCumference a proton and an electron would only like to combine if your nucleus is on the left side of the valley of beta stability.

Sir Cumference

Okay, my point is, for a white dwarf to become a neutron star, it must be energetically favorable for the protons and electrons to combine, right?
