PeroK's latest activity
-
PeroK replied to the thread Motion in 2 dimensions.Look at it this way. If you consider a graph of you against the other eight billion on Earth, then it would be impossible to see you on... -
PeroK reacted to haruspex's post in the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring with
Like.
In reality, not only are all ropes somewhat elastic, so are all blocks and all ropes have mass. Starting with such a completely general... -
PeroK replied to the thread B Does Time Pass at Different Rates on Other Planets?.Like a helicopter?

PeroK replied to the thread Motion in 2 dimensions.In that scenario, the component of velocity in the y direction remains constant. It would not reduce to zero.

PeroK replied to the thread B Does Time Pass at Different Rates on Other Planets?.Time, by definition, is measured in the same way everywhere. E.g. by a caesium atomic clock. An important question, however, is whether...

PeroK reacted to ObEffect's post in the thread Howdy from a particle geek - it is nice to find this community! with Like.
Hello, real name Todd here - and being a poor particle physics addicted geek has long meant inventing tools I couldn't afford. And now...

PeroK reacted to gmax137's post in the thread Interesting Documentary on the Dounreay Breeder Reactor with Like.
I didn't know much about this plant, intersting documentary.

PeroK reacted to weirdoguy's post in the thread B What reference frame is used for the velocity v in the Lorentz transformation? with Like.
I've been teaching physics since 2008, and I've spent 5 hard years becoming a physicist. We all here thought about these questions...

PeroK replied to the thread News JWST may be shut down by DOGE.It seems like you guys are cooked. Cutting funding for science is the least of it.

PeroK reacted to weirdoguy's post in the thread B What reference frame is used for the velocity v in the Lorentz transformation? with Like.
It seems that you're not here to learn, but to argue. Telling physiscists that they haven't realized the complexity of issue when you...

PeroK reacted to TensorCalculus's post in the thread Hello from an autodidact physicist wannabe with Like.
:welcome: I suspect you are at the start of your physics journey, and quite confident because you have not yet seen the masses you will...

PeroK reacted to Dale's post in the thread B What reference frame is used for the velocity v in the Lorentz transformation? with Like.
Not here. The place for questioning and doubting authoritative theories is the professional scientific literature. PhyscisForums is an...

PeroK replied to the thread B What reference frame is used for the velocity v in the Lorentz transformation?.There are different levels of "doubt". Suppose you started learning pure mathematics and immediately didn't understand mathematical...

PeroK replied to the thread Hello from an autodidact physicist wannabe.There are a lot of retired engineers, especially software engineers, who believe they have a grand unification theory. We get dozens of...
