:: If you've paid him for something then I won't complain too much about your complaint - if you haven't at least bought one of his books, then what does he owe you? I am always a little disappointed when he fails to update right on time (or for an entire week in the case of the What If? site), but seriously? I bought a $15 book? what's that worth to him? maybe several minutes of his time? He's given me so much more than that over the years - the least I can do is give him a week or two off from my demands for trivia and wit now and then. My apologies if I somehow mistook your comment as a complaint... -- [[User:Brettpeirce|Brettpeirce]] ([[User talk:Brettpeirce|talk]]) 15:42, 23 December 2014 (UTC) | :: If you've paid him for something then I won't complain too much about your complaint - if you haven't at least bought one of his books, then what does he owe you?

Transcript right now assumes two Astronomers. It looks to me like three.

Am I the only one who's bothered by this? It was funny right up until the "let's make out" comment at the end. Astronomy has a pretty serious [http://womeninastronomy.blogspot.com.au/2014/05/fed-up-with-sexual-harassment-defining.html sexual harassment problem], and as a woman working in astronomy I'd rather that wasn't made light of.

: I don't think Randall would consciously make light of such an issue. Sadly, it does make a kind of sense that it would be an astronomical problem, so to speak.

− | + | :Thanks for the reference. We don't know if harassment might be an issue in this case, but it's easy to see, especially in the context of oxygen impairment, that that could indeed be problematic, so I added a few sentences on that.

Oxygen concentration is constant regardless of altitude? So there is the same quantity of oxygen per cubic meter of atmosphere at sea level as at the edge of the atmosphere? And halfway to the moon? That doesn't sound right... [[Special:Contributions/108.162.221.169|108.162.221.169]] 04:39, 23 December 2014 (UTC) | Oxygen concentration is constant regardless of altitude?

: No. The number of oxygen molecules per volume of air (= concentration) is not constant, but number of oxygen molecules per total number molecules of air (= mole fraction) is practically constant at 21%. As the total air pressure decreases with altitude (i.e. fewer total number of molecules per volume of air), the absolute number of O2 molecules per volume (= concentration) decreases. -- Simon {{unsigned ip|173.245.53.215}} | : No. The number of oxygen molecules per volume of air (= concentration) is not constant, but number of oxygen molecules per total number molecules of air (= mole fraction) is practically constant at 21%.

:: I'm not sure if it's just way to explain more complex phenomena or if it really works that way in lungs, but I heard/read it's the partial pressure of oxygen which determines how you feel when breathing. Meaning, you will feel same effect in air with same partial pressure of oxygen no matter what the total air pressure will be. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 13:51, 23 December 2014 (UTC) | :: I'm not sure if it's just way to explain more complex phenomena or if it really works that way in lungs, but I heard/read it's the partial pressure of oxygen which determines how you feel when breathing.

What makes this even funnier/more silly (in my opinion) -- these days, with the use of digital cameras/detecting equipment and internet connections, astronomers usually don't even ''need'' to go up to these telescopes any more. They can stay at a more breathable altitude and get their data remotely. --[[User:Aaron of Mpls|Aaron of Mpls]] ([[User talk:Aaron of Mpls|talk]]) 06:28, 23 December 2014 (UTC) | What makes this even funnier/more silly (in my opinion) -- these days, with the use of digital cameras/detecting equipment and internet connections, astronomers usually don't even ''need'' to go up to these telescopes any more.
