Dale reacted to Herman Trivilino's post in the thread I What does equiprobable mean in the context of thermal motion? with
Like.
If I understand your question, the answer would be any vector not parallel to the y-axis will have a nonzero x-component. Not sure what... -
Dale replied to the thread I What does equiprobable mean in the context of thermal motion?.This is a statement of the isotropy of physics. There is no specific direction in the universe where things naturally align. The...

Dale replied to the thread I Conventionality of the One-Way Speed of Light.The conventionality of the one way speed of light (OWSOL) was recognized from the very beginning. In the seminal paper On the...

Dale reacted to TensorCalculus's post in the thread Suggestion Show pronouns of a person? with Like.
Okay so a simple one here: would you be able to show the pronouns of a user simply by hovering over their profile picture, instead of...

Dale reacted to kuruman's post in the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it? with Like.
I think that the first manned Moon landing in 1969 was a spectacular solution to the 3-body problem. I scrimped and saved for three...

Dale replied to the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it?.It is interesting to know that the first computers (e.g. the ENIAC) were built specifically to conveniently calculate non-analytical...

Dale reacted to PeroK's post in the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it? with Like.
The problem is that there are hardly any standard functions: polynomials, trig functions, exponential and logs. That's about it. There...

Dale replied to the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it?.I can definitely say it is solved because it is. Prediction in no way requires an analytical solution. Quite the opposite. To make a...

Dale replied to the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it?.Again, it is already solved. And assuming energy conservation and no collision will not make the solution analytic.

Dale replied to the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it?.It is already solved. The solution is just not analytic.

Dale replied to the thread I Energy of Electromagnetic Waves in Destructive Interference.The reason I said it is that energy is conserved if you arrange for a bright center or if you arrange for a dark center. Energy flows...

Dale replied to the thread I Relationship between nuclear magnetic physics and Maxwell's demon.I don’t see how they would be related. I don’t know of any way to physically separate hot and cold spins using MR.
-
Dale replied to the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it?.What makes you think it is not solvable? Are you possibly confusing "solvable" with "has an analytical solution" or "has a closed form...

Dale replied to the thread Physics inserted in society.Any “traction” that it has regained is due to social media and represents a flaw in social media, IMO. A couple thousand years ago the...

Dale reacted to Herman Trivilino's post in the thread I Why isn’t there an equation to describe how energy is redistributed by destructive interference of an electromagnetic wave? with Like.
Please don't draw that conclusion from the comment you replied to. So-called closed form solutions (that give exact results) are indeed...
