Yes. I agree with pretty much everything you have written about the distinction between real and fictitious forces. A real force (or...

The simplest explanation, IMO, is this: If you measure an object to be accelerating, then there are two different reasons for this: 1)...

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference...

A couple of guys I worked with tried that. They slept two hours a night in the Data Centre and clocked on for 150 hours one week. One...

The bit you have marked in red should be ##204 - 180 = 24##. PS and although you don't necessarily need an accurate diagram, your...

Your angle marked as 66 degrees is wrong. The bearing of 204 is from north, isn't it? So, what will be the angle made with the south...

Okay, so your question is why to use sine and not cosine? What if the bearing was 270 degrees?

Is there a diagram? I would have assumed from the question that the fly is flying horizontally.

Phew! I thought it might be Detox!

I don't see that the education system is responsible for that.

I don't think that makes sense either. There are two distinct spacetimes being considered. In both of them the infaller crosses the...

The question you need to answer is what you want out of the discussion. If you want facts about black holes then almost any source is...

I admit haven't done a scientific analysis, but I think it's almost impossible to understand relativity without studying it from an...

That would be the clever insult Dirac threw at a student who made a wild guess about the wavelength of visible light when he didn't...

By the same argument, you could vave $200 billion dollars annually by reducing the school year by 10 weeks. And, of course, you could...
