This was answered in your original thread. But you obviously couldn't be bothered to read it.

I guess it would have to have a similar mass to the Earth itself. In other words, about 2cm across. It would still take thousands or millions of ears to absorb the mass of the Earth.

So you haven't got this far in school yet? Basically, an orbit is an object falling as fast as the ground below it falls away. Imagine throwing a ball: it will go some distance then hit the ground. Now throw it harder: it will go further. Now imagine you could throw it so hard that it went to the horizon. But at that point the curvature of the Earth means that the ground has dropped away beneath it and so it keeps going.

Run away from the heat and radiation.

How are you going to do that when you don't know what a nuclear device is?

Run away.

Gravity. Magic. Or have I got those the wrong way round?

Antimatter means particles which have opposite properties to "normal" matter. For every particle, there is a corresponding antiparticle. For example, the anti-electron is the positron. Positrons are used in Positron Emission Tomography (PET) scans. http://www.radiologyinfo.org/en/info.cfm?pg=pet I can't think of any other practical applications at the moment. After all, we can only create small numbers of anti-particles.

No. It might make it slightly warmer, but that's all. There has been a lot of analysis of this, partly because some nutty people claimed the LHC could produce micro black holes. http://www.universetoday.com/1930/are-microscopic-black-holes-buzzing-inside-the-earth/ It is not really "made of" anything. It is a region of space where mass has collapsed below its Schwarzschild radius.

Hang on, I'm going to ring your babysitter.

You would be sent to bed early with no supper.

Chronic (physical) pain can cause depression and lead to suicide. Maybe it prevents you getting burned in more metaphorical ways.

It is a discussion forum. People are discussing your points. You seem upset because they are pointing out the many ways you are wrong. Perhaps that is why your answers have been getting more irrational and seemingly with no connection to the subject. You gave me no reason to read it again. Nevertheless, I went back and read Ch. 11. Now what? It didn't tell me anything new.

You are referencing a religious text, so why shouldn't that fact be mentioned? That was not an assumption. It was a logical statement used to show that your premise was false. What do antibiotics used in farming have to do with it? It may be true that there is a greater risk of infection due to intensive farming, but it has always been considered unsafe to eat undercooked chicken. What does this have to do with the topic? Or are you just agreeing that all cultures have "folk rules" about food preparation? Sometimes these get put in religious texts and become "law" (to the subset of people who think anything in the texts must be taken literally and never re-interpreted). Again, how is this relevant? Who is making that assumption?

Flu is deadly; it kills millions. But we still don't have a cure. You seem to be getting confused between how a, primarily, animal disease can get transferred to a human verus how it spreads once it is in the human population. But, for the many reasons given, this is a totally different scenario from the possible health risks or other reasons to be averse to particular foods. So it took thousands of years to spread around the world. How is that relevant?

The difference is that a tuning fork resonates at a single frequency. The stapes simply transfer the complex vibrations going on in the air to the inner ear. So a tuning fork will vibrate like a sine wave, but the stapes will vibrate like:

You could recruit a robot army: https://what-if.xkcd.com/5/ Seriously? You know that blue underlined text? That is what is called a "link". You can click on it and read more information.

You can only do a Fourier transform over some sample period (ideally it would be infinite but that isn't usually practical). The envelope, and any other characteristics, are encapsulated in the range of frequencies generated by the Fourier transform. For example, a single frequency is only really a single frequency if it is infinite in duration. If it is of shorter duration then there are more frequencies present. If it has a sharper attack and decay, then there are relatively more high frequency components. See also: the uncertainty principle.

You don't seem to be taking these answers very seriously. Maybe you should give the computer back to your mum and get on with your homework. I did wonder if getting everyone to jump at the same time would cause enough damage. It turns out it would be pretty bad, but not that bad. https://what-if.xkcd.com/8/

I'll have a go this weekend.

You can add up the (relatively) simple vibrations of each sound to give the more complex vibrations of the combined sound. Computationally, you can do the reverse - a Fourier transform - where you take that complex vibration and turn it into a list of individual frequencies and their amplitudes. The ear has thousands of tiny hairs in the cochlea. These respond to different frequencies and so, effectively, do a Fourier analysis of the sounds entering the ear. The brain then uses the information from these hair cells to turn the vibrations into meaningful sounds. How the brain is able to pick out one voice in a crowd, or the flute in an orchestra is, I think, still a bit of a mystery. I assume it is some sort of complex pattern matching - it knows what combination of frequencies make up that particular voice or instrument and filters them out from the background. Despite certain TV cop shows, I don't think that can be done by computers yet.

Without wishing to be rude, maybe he means his mental equipment rather than his computer.

It depends on the type of generator you are using. But one of the benefits of running the lights from the battery is that most types of batteries will give a fairly constant voltage. If they don't you use a DC-DC convert to get a constant voltage out. This sounds like an incredibly complicated way of achieving that. I'm not sure what "excess energy" means in this context.
