PeroK's latest activity
-
PeroK replied to the thread B How to calculate this conditional probability?.Okay, I got confused. I thought two were condemed, but I see two are released. Let me look at it again. -
PeroK replied to the thread I Why fixed point iteration of ##x^3 = 1-x^2## doesn't converge when ##x_0= 0##.You need two dollars or two hashes to delimit your Latex.

PeroK reacted to Jaime Rudas's post in the thread I No symmetries in the Universe at the Big Bang...? with
Informative.
In this regard, I found that, under reasonable assumptions, the Borde-Guth-Vilenkin theorem demonstrates that inflationary cosmological... -
PeroK replied to the thread I Problem in understanding instantaneous velocity.It's not possible. Instantaneous velocity is part of the mathematical model. In Newtonian physics you can postulate that a particle...

PeroK replied to the thread Curious Young Physicist Exploring the Universe."I" before "e", except after "c"; but not if the word is "weird"!
-
PeroK reacted to Ibix's post in the thread I Topic about physics axioms, theory, laws etc.. with
Like.
No. The point is that maths isn't generally about truth, it's about self-consistency. Physics needs self-consistent models, but they... -
PeroK replied to the thread B Energy-time uncertainty relation for a volume and macroscopic objects?.It's nothing like that. Time is not an observable in QM; it's an independent variable, unrelated to the particle itself (unlike the...

PeroK replied to the thread I Problem in understanding instantaneous velocity.I suspect we might be arguing about words here.

PeroK reacted to weirdoguy's post in the thread I Problem in understanding instantaneous velocity with Like.
No, the limit of those lines is the tangent line. You are confusing limit with the sequence and whether or not it's part of the...

PeroK reacted to Svein's post in the thread I Problem in understanding instantaneous velocity with Informative.
Copyied from "Real Analysis" (H.L. Royden): These are topological spaces. T_{1}: Given two distinct points x and y, there is an open set...

PeroK reacted to Mike_bb's post in the thread I Problem in understanding instantaneous velocity with
Agree.
No. Limit doesn't mean the process of approaching to the tangent line itself. Limit is just a number (coefficient of tangent line slope). -
PeroK reacted to Gavran's post in the thread I Problem in understanding instantaneous velocity with
Skeptical.
No, it does not. The limit means that the secant line approaches the tangent line, but it never becomes the tangent line.
