PeroK's latest activity
-
Just to add to existing answers, this is a (sadly) common misunderstanding. In relativity it turns out that there is considerable... -
PeroK replied to the thread I Is there anything inside a black hole?.There are already a lot of threads on this. The Schwarzschild black hole is an "eternal" black hole, which is a solution to the...
-
It's not symerical, because the light source is at rest in one frame, but not the other. Motion relative to some random light source...
-
PeroK replied to the thread Coulomb's force vs the Lorentz force.The error was caused by an excess of positivity on the one hand and an excess of negativity on the other; and, a general lack of neutrality.
-
PeroK replied to the thread I The Einstein Clock aka Light Clock.The light clock is really very simple. If you accept the invariance of the speed of light, then time dilation, length contraction and...
-
That's what I call a discussion. Right, I want to summarize now what I see, because I can't really reply to all the minor things that...

PeroK reacted to SomeBody's post in the thread I 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 B 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 B 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 B 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 replied to the thread B Why would an atmosphere without greenhouse gasses be colder than with them?.A lot of what has been posted in this thread was already posted in your previous thread from four years ago...

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 B 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...
