Thanks @willyengland ! Section 5 (page numbers 38 to 41; pdf sheets 49 to 52) is titled "Extension to the Tangent" and provides a proof that refutes the general case of a rational tangent of a rational angle in degrees. The result is state in his Corollary 3.12 which reports the only...

According to Wiki, the case against rational tangent of rational angle in degrees is provided in Nivens "Irrational Numbers" - a book that I do not have. But that is the specific case required by the OP.

This is a big clue. Don't click this unless you're ready for a spoiler.

Is this a stone counter top or something else? And, of course, you are looking for a solution short of replacing the counter.

Welcome to these forums! Scientific American published an article just yesterday about minerals found at a little test site 200 miles to your south. It was the product of an old experiment that was based out of Los Alamos.

Welcome to these forums. You have more of a question than a theory. But by calling it a theory, you may run afoul of the PF "Terms of Service". I suggest you retitle this post as "Question" rather than "Theory".

Not "wave", "wave function". It provides the weighted distribution of all the places where you might find a particle. When used that way, it directly reflects exactly what is found in particle experiments. So, it is not an "interpretation". Any description of what is going that is consistent...

A photon that is "absorbed and reemitted" will likely leave behind energy and end up with a higher wavelength. Or, in the case of a laser, stimulate the emission of light at a lower wavelength. At a QM entity, exactly what happens when a photon is travelling is not simple. The landing spot of a...

OK. Since you're a mutt, I'll make sure she gives you a treat. Welcome to these Forums.

You appear to have no stator. You need something for those electromagnets to pull towards. Something of iron or steel that is solidly fixed to a position close to where your rotor will be spinning. You will probably want two of these stators, one for each of you two electron magnets. In each...

To be clear, you have made left turns more efficient when thermaling by making the plane asymmetric. When flying the Schweizer, I was equally able to enter a thermal in either direction. I was told by my instructor that should I ever do competitive soaring, I would have an advantage - since...

You will have a rolling ball, some internal control masses (spinning, static, or some of each), and some ability to apply force to those masses. You can pick a Cartesian coordinate system (x,y,z) to describe the positions within the ball of that internal machinery. I think the biggest problem...

The vapor pressure tells you how eager the ice is to sublimate - to become a vapor. Vapor pressure drops exponentially as the temperature drops. The water vapor pressure of the ice in those permanently shaded regions of the moon is so low, that there are more water molecules that happen across...
