How is your teaching going, caek? Do you generally like your students or wish them to hell? What about your fellow faculty? Administrators?

i'm missing research more than i expected, and i am continually staggered by the amount of paperwork, government involvement, financial complexity and bureaucracy at private universities in the US compared to public universities in europe. (seriously, lol at any american, politician or otherwise, who cites european governance as some kind of sclerotic basket case.)
but basically on the day to day, i love it!
any more and we'd have to move this thread to 77.

hmm. odd article. fairly well understood theoretically, looks like a valuable but incremental practical advance.

Would be interested if you consider this credible, a new model of the Thea collision that incorporates a previous smaller moon into the mix.http://nautil.us/issue/13/symmetry/when-the-earth-had-two-moons

i kind of struggled to get through that moon article. it is not crazy but my undersrtanding (not a solar system guy) is that there is a less crazy idea that is the "consensus".

Nautilus seem to have a knack of making ropey premises seem credible, starting to think that is their MO.

"We should be grateful for this deep reservoir," says Jacobsen. "If it wasn't there, it would be on the surface of the Earth, and mountain tops would be the only land poking out."

It is a headfuck thinking about where all the water comes from, it seems like there is too much to have been delivered by comets alone.

oh some crazy moon has an ocean under its surface, wait so does our planet.

i was not aware of that! that is cool. the NS article is a bit casual about the difference between "evidence for" and "consistent with", but otherwise seems legit.

is it possible that the molecules in a liquid can remain static
― Little Saint Hugh of Lincoln (nakhchivan), Monday, 30 June 2014 21:57 (nine years ago) link
like if u had liquid in a container with no gravity acting on it and heat/pressure was consistent would it still be moving
― Little Saint Hugh of Lincoln (nakhchivan), Monday, 30 June 2014 21:58 (nine years ago) link
no the molecules must be moving (goes for solids and gases too)
that's the definition of non-zero temperature
they stop moving by definition at absolute zero, but absolute zero is a theoretical limit and cannot be reached by a liquid

thank you for the martin rees recommendation in some other thread, been enjoying "our cosmic habitat".

martin rees's dad was our family GP when I was a kid -- he looked like the mekon, except tall
― mark s, Monday, 30 June 2014 22:12 (nine years ago) link
sounds like martin rees but tall
― caek, Monday, 30 June 2014 22:13 (nine years ago) link
come to think of it I was quite small so possibly not that tall
― mark s, Monday, 30 June 2014 22:15 (nine years ago) link
so the difference is that solids will vilbrate but the movement of molecules is constrained within that, like a lattice structure or whatever, so they can only move to a certain extent? whereas in a liquid the molecules will move around independently, interchange positions, etc?
― Little Saint Hugh of Lincoln (nakhchivan), Monday, 30 June 2014 22:15 (nine years ago) link
yeah in a solid things are constrained, but still jiggling
in a liquid (absent gravity, boundaries of container, etc.) things can go wherever
― caek, Monday, 30 June 2014 22:16 (nine years ago) link
thank you that is exactly what i wanted to know
this was inspired by imagining the molecules moving around in an inert, cellared bottle of wine
(im drinking wine rn)

caek i read the other day that absolute zero is no longer regarded as the point at which atoms cease to move but at which they attain the lowest possible (theoretical) energy state, is this right y/n?
― clockpuncher (Noodle Vague), Tuesday, 1 July 2014 06:21 (nine years ago) link

― do u like green ez & jam (darraghmac), Tuesday, 1 July 2014 07:20 (nine years ago) link
anyways idk re particle motion but absolute zero occurs on the saula rd around mid November,normally when the taxi has gone home and you've lost yr jacket
― do u like green ez & jam (darraghmac), Tuesday, 1 July 2014 07:21 (nine years ago) link
not sure exactly what your article was talking about NV but...
yeah 'cease to move' is the classical description of what goes on at absolute zero
in quantum mechanics it's not that simple because they're delocalized (i.e. their location is fuzzy via the uncertainty principle)
