PeroK reacted to HanLi's post in the thread High school student with a passion for physics, looking to learn with
Like.
Hello everyone, I'm a 16-year-old high school student from China. I've been fascinated by physics ever since I watched science... -
PeroK reacted to Ibix's post in the thread High School What Medium Does Light Travel Through in Space? with Like.
I think you haven't quite caught the point here. We know why ##c## has the value it has - because when we picked some artifact and...

PeroK replied to the thread High School What Medium Does Light Travel Through in Space?.We could phase the question like this. Human beings are on the scale of 1-2 metres. And the human heart beats about once per second...

PeroK reacted to weirdoguy's post in the thread High School What Medium Does Light Travel Through in Space? with Like.
Over the years here I've seen tons of threads about that, and I think no one ever grasped what people are actually asking about...

PeroK replied to the thread High School What Medium Does Light Travel Through in Space?.Don't try to tell me that SI units are a European conspiracy to try to confuse Americans!

PeroK replied to the thread High School What Medium Does Light Travel Through in Space?.Accelerate a charged particle to high energy. If its speed goes up according to ##E = \frac 1 2 m v^2##, and eventually exceeds the...

PeroK replied to the thread High School What Medium Does Light Travel Through in Space?.This thread seems to over-complicating things. The speed of light is invariant. That is determined by experiment. At least to the point...

PeroK reacted to tech99's post in the thread High School Conclusions from Thomson’s cathode ray tube experiment with Like.
It seems that they did know that charge flowed in a circuit. Thompson himself tries to measure charge by the time it takes to accumulate...

PeroK reacted to Dale's post in the thread High School What Medium Does Light Travel Through in Space? with Like.
I disagree with many claims in any MDPI journal. They are, in my opinion, a predatory publisher with unethical practices. If you wish...

PeroK reacted to Averagesupernova's post in the thread Why does the movement of electrons create fields? with
Skeptical.
My intent here was to share a video. It right, it's wrong, it's whatever. I'm not claiming the existence of magnetic monopoles. Watch... -
PeroK reacted to Matterwave's post in the thread Why does the movement of electrons create fields? with Like.
See @renormalize post #22. The asymmetry comes because magnetic monopoles, as far as we know, do not exist. This asymmetry is indeed...

PeroK reacted to Averagesupernova's post in the thread Why does the movement of electrons create fields? with Skeptical.
This is the one I'm referring to. It has been a while since I watched it. There are other YouTubers that have made videos that agree.

PeroK reacted to A.T.'s post in the thread Why does the movement of electrons create fields? with
Agree.
Electric field and magnetic field are both components of the same (electro-magnetic) field. Saying one is a special case of the other... -
PeroK reacted to renormalize's post in the thread Why does the movement of electrons create fields? with Like.
Actually, both the electric and magnetic fields are on the same footing as part of the Maxwell's "unified" electromagnetism. Any...

Each electron makes EM vector field individually. They superpose to be an observed EM vector.
