In an liquid fluoride thorium reactor, how is the reaction started? My assumption would be a piece of fissile material would be somehow inserted into the fuel to introduce neutrons to the solution, but I have not found any information to show if this is how the reaction is started. If this is...

In a reactor using Th232 as a fertile material to breed fissile U233, what is the amount of energy released per kg Th232 compared to a reactor using about 20% enriched uranium?

Maybe $1,000. I am going to build it in stages though, so it won't be all at once.

How are space shuttles accelerated to escape velocity? Would it be possible to build a rocket at home that would be capable of getting into space if it were to use liquid hydrogen and oxygen as fuel?

I didn't think that the atmosphere just ended suddenly, I only thought that after around that height, an object is basically considered to be in space.

I was told that it was about 13km, but thank you that helps a lot.

My friend and I are using weather balloons and a rocket to send a camera into space. We need to know how far from Earth we must be to not have the camera fall back. The edge of the atmosphere is around 13km and we can easily get past that. We have 2 weather balloons with a 100,000 ft breaking...

Thank you for your input everybody. I will take your advice. I'll save this for another day. Best of luck, Dylan

I was in my AP Physics class discussing wavelengths of the electromagnetic spectrum and I came up with the idea to attempt a gamma ray microscope. Of course this is extremely dangerous, so I will have to be cautious (and use a lot of lead). Is there a way to produce gamma rays? I know they...

I am new to electrical systems, but I wanted to know, how would someone be able to make a piece of metal positively charged for a short time and pulse?

This is very helpful. Thank you.

I found a PDF with some information. Thank you for the suggestion.

I have been curious for a while, but have not been able to find a decent source of information. What are all of the subatomic particles? I know the obvious protons, neutrons, and electrons. But what are the others and what do they do/ are associated with? Like "gravitons" being the supposed...

Thank you so much! I will take a look at these books right away!

Well, i guess it looks like i am going to be reading some math books!
