FactChecker reacted to Halc's post in the thread I Question of accuracy of galactic collision simulations with
Like.
There are countless time lapse simulations of galactic collisions, squashing say 20 billion years into a few minutes or even seconds... -
FactChecker reacted to ohwilleke's post in the thread I Question of accuracy of galactic collision simulations with Like.
This is definitely a possibility. When you are comparing simulations to astronomy observations, I focused on the issues with the...

FactChecker replied to the thread I Question of accuracy of galactic collision simulations.An amateur question: Can it be that the observed collisions display a bias? When there is a lot of friction, therefore heat, would they...

FactChecker reacted to .Scott's post in the thread I Question of accuracy of galactic collision simulations with Like.
Which, of course, will limit the usefulness of the discussion. I think you are over-stating how much friction is involved. Wherever...

FactChecker reacted to ohwilleke's post in the thread I Question of accuracy of galactic collision simulations with Like.
Astronomy/cosmology simulations do two main things: 1. They rely on a set of assumptions about the physics involved, which are physics...

FactChecker replied to the thread Volume with spherical coordinates.I still don't know what you are talking about. A diagram might help. If you have a question, please don't feed us information a little...

FactChecker replied to the thread Volume with spherical coordinates.You may need to start at the beginning and describe the problem better. I have no clue what you are talking about. What is ##a##...

Maybe I'm a bit dumb, but you have to be a bit more specific if you want to receive help. Personally I can't make anything out of this...

last for me of Pine Creek canyon, looking SW, at right in photo. Huge Mt. Tom at canyon's entrance, 13,658', base down in Round Valley...

FactChecker replied to the thread If you think having a backup is too expensive, try not having one.I think I will not live long enough to worry that someone owning a quantum computer will try to crack my password safe file. IMO, by...

How little is little? Wish there was a (required) ruler underneath to give this. Never saw oil shale before or in an open pit...

To drag myself back on topic, another thing I've seen in real life but don't have good photos of: This is on the north coast of Arran...

FactChecker replied to the thread I Apparent counterexample to Cauchy-Goursat theorem (Complex Analysis).Right. I was just trying to stay as basic as possible.

FactChecker reacted to mathwonk's post in the thread I Apparent counterexample to Cauchy-Goursat theorem (Complex Analysis) with Like.
It is true that OP has not checked simple connectedness. However, although the theorem stated specifies simply connected, all that is...
