The surface of a moon is not a good place to live. It is not exactly windswept, more likely it is UV sterilised. Maybe drill a hole down several kilometres, then fill the hole with a blend of xenon and oxygen. That should retain a subsurface atmosphere, with sufficient pressure and oxygen that...

Only the electric and the magnetic fields oscillate either side of zero. The energy in the wave already travels in a straight line that is called the Poynting vector. https://en.wikipedia.org/wiki/Poynting_vector

You show two fulcrums that carry the load. The load will not slide over a fulcrum, that needs to be a roller. If FR1 and FR2 are due to weight, then they should be vertical, not diagonal.

Welcome to PF. The observations you report are inconsistent with what we know about the physical world. While it is possible to screen a human body with electrical and magnetic conductors, it is more likely that the placebo effect would be in play, as the observed symptoms appear to be...

I cannot lie. My dad told it to me long ago. You can google some of the many versions. Another more educational one ... Little boy on the railway track, the engine gave a squeal, and then the driver took a spade, and scraped him off the wheel.

The God of thunder, crossed the skies, upon his favourite filly. "I'm Thor", he cried, and the horse replied, "You've thorgotten the thaddle, thilly".

I think this one needs a bit more work. "How should you fold a parachute"? "The same way that skydivers who live in Australia folded their parachutes". "But won't that mean you will land upside down"?

https://en.wikipedia.org/wiki/Tropical_cyclone "Depending on its location and strength, a tropical cyclone is called a hurricane, typhoon, tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or...

Why not heat a stainless steel water container, that is fixed-in-place? If heated from below, the water will circulate and mix, so ice will not form.

"Knowing assembly better" is an interesting concept. You only need sufficient knowledge of assembler to solve a problem today. You can look up the details when you need them. Next week you may be reading and writing a different processor code. The C language is an envelope that you can use to...

The heater power needs to overcome the thermal losses from the plate. Those losses are proportional to temperature difference between the plate and the environment. Without a thermally conductive or convective plate, increased power will cause a local hot spot. The temperature of that hot spot...

I write a high level language package, then optimise it by hand assembling, only the critical inner loops that are intimately coupled to the hardware. I let the compiler sort out the system interfaces and data allocation. There are so many texts, with so much useless code that you do not need...

Stop trying to do it the hard way, by considering too many things. Do you have an old PC that runs C ? Download the free x86 pdf manuals from intel. Most PCs are intel x86 compatible, new platforms are starting to appear. It is difficult to make a complete system from scratch that works. It...

The easiest way to learn is to work within an existing system. Start with your friendly C compiler, one that allows you to examine the assembly code generated by the compiler, and also allows insertion of inline assembly language blocks into the source code, using something like; ASM and END...

What will the cantilevers be attached to? I would question whether the existing building structure could carry that additional supported load.
