@Asaad-Hamad We can answer questions, but we can’t make you like the answer. The questions in the original post and repeated in #11...

Oh, ok. In Poland not that much, so I guess I didn't notice the context. They are not pedantic, they are sick and should not be close...

You did not check how Lorentz force works, did you? It's a high school topic, so there are plenty of materials. Particles move on a...

Long time ago I read a set theory textbook where author said that Venn diagrams are way more general tools then most people think. He...

Why drawings are mentioned so much, when one can write equations without them? Some of you didn't have to make living out of teaching...

Heck, a Venn diagram is just the most basic representation of shared sets isn't it? Why is it mentioned so much? I mean why does it seem...

They only introduced notations and names without any motivation or use. I agree. I don't know why they are taught.

Yes. And I'd like to point out that Venn diagrams are particularly effective for communicating with non-mathematical audiences. At one...

Visualization! Symbols can be nice. Visualization can also be nice. More to say, but that should be enough.

Why exactly? Do you know how Lorentz force works? What does changing the sign of ##\vec{B}## do to particles movement? Hint: magnetic...

It can be assumed that on the way to Earth under the influence of the interstellar medium the signal is heavily distorted and becomes...

But the evidence base is very thin so far. "Most of them are not repeatable, most of them are highly unpredictable, and only five out of...

It's not my personal opinion! How many industry experts do you require? OK, let's do that, then*. * unfortunately, in blocks of text...
