Someone should put together some rules for thought experiments telling what you are allowed to do. Are you allowed to pretend you are an observer inside the thought experiment? If so, are you allowed to change which observer you are in the thought experiment? The physicists never got together to...

If the marbles were orbiting each other at the correct rate of rotation to counteract gravity the distance between them would remain fixed at 10 million light years. However, there's nothing to use as reference to determine if the marbles are orbiting each other, there being no background stars...

My guess is if you could predict the future with 100% accuracy, by whatever method, that would force the wavefunction to collapse because you have knowledge. Without the wavefunction the universe would end and everything would vanish. It is for this reason the future cannot be known. You...

I looked over two books; The Little Book of String Theory, and also the critical book Not Even Wrong. String theory math is too much for me and I don't understand it. I personally believe that string theory is a collaborative effort with many brilliant minds making contributions and tinkering...

Electronic engineers call it the "j" operator (so as not to confuse it with current). It's trig intensive and they use Euler's formula and De Moivre's theorem along with phasors to make calculations easier. It's a means to an end.

(I know I didn't come up with the above argument, but I don't recall anymore which of the various FAQ's mention it.)They used complex numbers to come up with the theory of black holes. The reality of black holes must be like the reality of the square root of negative unity, i=√(-1).

To prove theorems in Calculus you have to use limits. Physicists and engineers use infinitesimals to solve problems, but they don't mean infinitely small. They mean small enough so the error becomes negligible. I don't know who this guy Robinson was. Sounds like a rogue mathematician.

I've been amusing myself by spending time editing the Elements.

The CFLs don't always last seven years like it says on the package. Some of mine were gone in a month. A couple were smoking when they went out. I suspect the market is being flooded with the cheapest chinese clones.

Maybe we did, but the source LGM-1 was later downgraded and written off as being a rotating neutron star.

I have a question that's even more stupid. Is the past "unique?" Perhaps there are two slightly different pasts that could result in the present, and one is just as valid as the other. That might explain the arrow of time, anyway. Time moves in the direction from cause to effect because...

Does that say anything about the Schwarzschild radius? If we observe the universe is expanding, does that mean we're not sitting in a black hole?

Then what skills do we need? What should we study? Have your read the tale of John Henry? He tried to compete with a steam powered hammer. Don't try to beat a machine. Don't try to be like the computer.

Persons totally blind since birth don't notice they're blind. They don't see with their eyes. What does it mean "to see" anyway? The blind use cruder methods to get information about their surroundings; like probing with a cane and using the other four senses. In this way they see but they...

Be careful what you wish for! You will notice that red fire alarm with piezoelectric element on the wall. It WILL damage your hearing. Every month they will do a test: "We will be testing the fire alarm. Please remain in your work areas." If you do anything strange like wear hearing...
