PeroK replied to the thread Help me to clear my doubt about a problem of Classical Mechanics (Car and Bicycle).It's actually a continuous function. -
PeroK reacted to ShadowKraz's post in the thread B Is space stretching or is new space being created? with
Like.
On looking at the maths with a limited understanding of it (somehow calculus defeated me in my college days), I leapt, with the help of... -

PeroK reacted to Sagittarius A-Star's post in the thread I Confused about time dilation -- motion vs energy with
Informative.
As others mentioned, that's wrong. The following explanation in a local scenario shows, that "gravitational" time-dilation happens also... -
PeroK replied to the thread I Confused about time dilation -- motion vs energy.The energy and momentum of a clock depend on its mass. The measured time dilation does not.

PeroK replied to the thread B Onto set mapping is the surjective set mapping, and into injective?.Whether you use into and/or onto is upto you!
-
PeroK reacted to Gavran's post in the thread B Onto set mapping is the surjective set mapping, and into injective? with Like.
To be on the set means occupying the whole set in a particular way and the word “onto” follows the definition of a surjective function...

PeroK reacted to berkeman's post in the thread EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity) with Like.
Those are very tiny signals, and not likely to cause any physical effects. Folks here at PF have lots of experience with EM shielding...
