Spacetime is a coordinate system by which positions, velocities, accelerations, etc., can be measured. Some interesting and, IMO, fun easy reading on the subject which do not require extensive mathematics are: 1) The first chapters of "Mr Tompkins in Paperback" by George Gamow 2) "How To Teach...

It might be better to say that parts of the wave, each part coming through an associated slit and spreading as a simple sphere, interfere with each other to create the total wave. The combined total wave is the only thing observable in an experiment result. ADDED: The experimental results close...

This is about the amount of magnetic flux going through the open loop of the rotating wire. That is changing as the wire rotates. With the wire loop oriented as shown in the diagram, no flux passes through it. When the wire loop rotates, that changes to a maximum flux through the loop when it is...

Blaming AI is not logical. Anything, with or without AI, that is designed to optimize profits and has no moral constraints will do immoral things. We might as well blame the operating system it runs on.

If some constraints are left out of an optimization problem, they may be exceeded. That is not an AI-only characteristic; it is a simple fact about constrained optimization.

IMO, we can talk about this without invoking QM. The QM wave function is related to the probabilities of a particle being in a certain position. Is any probability function real? It is the way to express the likelihood of an event, but until the event happens (or doesn't), what is "real"? This...

Are we talking about the thing that is represented? Or about the means of representing it?

Subatomic particles present wave-like behavior that is real and measurable but is not classical particle behavior. It's not just a mathematical trick.

Here is a good video on Linux alternatives for Microsoft Office that compares the compatibility of formats. ExplainintComputers: Best Linux Microsoft Office Alternatives. Most are not exactly the same. None are perfect.

I sincerely hope this will cause all software developers to make Linux versions. The lack of tax software on Linux keeps me on Windows.

This makes it sound more serious than some of its government computers. And as the government goes, so goes a lot of civilian computers. "France just handed Microsoft a termination notice for 2.5 million government devices. Every ministry must submit a Linux migration plan by autumn 2026."

Ok. What real number immediately precedes 2? ;-)

Good question! And it's not just the sequence that the brain can remember, it can also remember the pace of certain things, like songs. So both the sequence and the timing can be remembered, separately or together. ADDED: In fact, remembering the temporal aspects like sequence, timing, and...

I personally think that GR's explanation of why ##M_i=M_g## is one of the most intellectually satisfying things in physics.

Give yourself time to think about it. GR is a profound change in our thinking.
