If you could only use 3-5 textbooks to learn math from prealgebra/algebra to complex analysis what would you use? Books that are as rigorous as Spivak's calculus, perhaps a proof based look at algebra etc.

building a liquid fluoride thorium reactor. a 2-3 kilowatt hour type thing, very small core.

what's a LFTR you ask? watch this

i called the NRC and oak ridge, turns out it's legal to own about 200 grams of uranium 233 (the primary fissile material). half a pound of fuel should do me well. As for thorium, i'm not really sure.

However i'm still not sure where i can get/make some nuclear grade graphite for the core moderator or some Hastelloy-N to coat the interior of the pipes and machinery.

<--- this is my super ultra basic layout. i might remove the beryllium tower assembly and just let the Pa233 decay in the thorium blanket and continuously gasify the U233 out of the blanket.

so, tl'dr, questions;
1) any places i can get hastelloy-N? perhaps some metallurgy places that could make it from scratch? or even better, guides to make it yourself?

2) places to get some nuclear grade graphite? perhaps from a university?

3)places to get thorium?, easy version would be thorium nitrate which is used (i believe) as a detector of specific minerals in water lines. but i don't know where to get a lot of that.

An object with mass can't reach the speed of light, because it would require an infinite amount of energy to reach that velocity. That I do understand. Here's what I don't understand: can't reach the speed of light in relation to what?

?"We want to stand upon our own feet and look fair and square at the world -- its good facts, its bad facts, its beauties, and its ugliness; see the world as it is and be not afraid of it. Conquer the world by intelligence and not merely by being slavishly subdued by the terror that comes from it."-Bertrand Russell
