Drakkith replied to the thread B Generator shaft rotation through spring and magnet (Is this feasible in Physics?).Let's say the battery outputs 100 watts to the circuit that includes the generator. The generator will receive 95ish watts thanks to...

Drakkith replied to the thread Hair's influence on the brain.Nice. I'm bald, so now I have an excuse to go inside instead of mow my yard. "My brain is too hot because I don't have hair to cool it...

Drakkith replied to the thread Speculative theory.It's fundamentally flawed, as such a model doesn't match our observations about the current and past state of the universe. As PeroK...

Drakkith replied to the thread B Generator shaft rotation through spring and magnet (Is this feasible in Physics?).Obviously you cannot use the battery's electricity to charge itself, so I hope that's not what you were trying to do. You cannot even...

Drakkith reacted to Owe Kristiansen's post in the thread B Use Surface-Volume to approximate gravity for planets and protons with Like.
Thanks so much — I really appreciated your comment. I was aware that surface area and radius are connected through A = 4πr², but I...

Drakkith replied to the thread B Use Surface-Volume to approximate gravity for planets and protons.Your formula: g ≈ (4π G M) / A Surface gravity formula: g = GM/r² Surface area of sphere formula: A=4πr² Isolating r² of SA formula: r²...
