PeroK reacted to SomeBody's post in the thread Undergrad Apparent counterexample to Cauchy-Goursat theorem (Complex Analysis) with
Like.
I posted this question on math-stackexchange but apparently I asked something stupid and I was downvoted. I still don't have an answer... -
PeroK reacted to Dale's post in the thread High School Why would an atmosphere without greenhouse gasses be colder than with them? with Like.
The atmosphere is in contact with three other thermal reservoirs, the earth, the sun, and space. Earth: heat transfer is by...

PeroK replied to the thread High School Why would an atmosphere without greenhouse gasses be colder than with them?.I guess you could start by looking at the temperature gradients within the atmosphere itself. The critical factor for climate change is...

PeroK replied to the thread High School Why would an atmosphere without greenhouse gasses be colder than with them?.Do you mean that if the atmosphere started at a temperature of +15C, say, and all the GHG were removed, then you don't understand why...

PeroK reacted to Genava's post in the thread Simple explanation of greenhouse effect - right or wrong? with
Informative.
Historically, the "Greenhouse Effect" is a simple thing emerging from a few observations and to explain divergences from an intuitive... -
PeroK reacted to sophiecentaur's post in the thread High School Why would an atmosphere without greenhouse gasses be colder than with them? with Informative.
Sorry if I'm stating the obvious here The GHGs are in a long vertical column ('cylinder' of air) of the atmosphere. This is a diurnal...

PeroK replied to the thread Coulomb's force vs the Lorentz force.I agree, it would be odd if they diverged. To see this, consider the frame of reference moving with the beams. That is to say, the...

PeroK reacted to jedishrfu's post in the thread How to increase phone signal strength by lying about it with Like.
Hey you can either round down and be a negative nellie or you can round up and be a positive pauline. There was a story told many...

PeroK reacted to Ibix's post in the thread How to increase phone signal strength by lying about it with Like.
"Mate, your signal strength is always better than mine. What network are you with?"
