The two versions of Monty Hall, in terms of calculation look like: Monty Hall (proper game) has three equally likely scenarios...

Two points: 1) You can write a computer simulation of both games. And count how often the stick or switch decision wins. In one...

The key points are: The upward force on the mass must be at least ##Mg##, where ##M = 25kg##. Each cord must supply half that force...

That's the only way to do it! After all, the 3 m height of the poles has no effect on the distance from the top.

I think the flaw in that logic is that, at that age most (though not all) students are not yet wise enough to know what's best for them...

I asked Google AI about this: " AI Overview Yes, a large and growing percentage of kids are using AI for homework, with some studies...

When I was growing up there was a children's TV serial called "The Changes". The plot was that everyone woke up one day and were...

Part of the problem is that the technology oligarchs have got western society under their control. Nothing can happen until we have...

The following is taken from Bjorken and Drell, Relativistic Quantum Mechanics (1964), pp. 5-6: So the problem with the Klein-Gordon...

It seems more logical to me to calculate the tension as a function of the distance from the top. Then the height is 3m minus this distance.

Why is it a problem to say that the midpoint if ##(0, 2)## is ##1##?

Yes, in the general case ##\mathbf{A} = \mathbf{A}(x,y,z,t)## is some vector field that depends on position (and time), and you'll need...

Everything. A finite open interval can be defined to have a midpoint in the obvious way. Compactification and Hausdorff distance have...

I think there's no such thing as the middle/midpoint of an open interval in the Standard Real line. Maybe in the 1- or 2- point...

A quick search suggests that midpoint normally applies to a (finite) line segment.
