I've seen an explanation that the engine pushes against the exhaust and that's what creates resistance for propulsion. I can't see that, as the exhaust in the void and again provides no resistance.

Can anyone explain this?

We only use 18 % of our brain in carrying out day to day affairs. The only person in human history to utelize 22% it his brain was Albert Einstien. the question is "is it possible to "kick start" the rest of the brain to get the password to unlock the mysteries of the real ultimate truth ? if at all there is a truth true enough to be considered true ? secondly, it is known all around that there are some star in the universe so far away that their light reaches us after say millions of years after death (supernova) . Doesn't that mean that we are actually living in the past of the universe ? What is happening around us has actually happened.

Alright, fire is obviously not a solid or liquid, I'm pretty sure it can't be a gas, but is it a form of plasma? Ionized gas? Or is it simply an energy given off by a chemical reaction and isn't a state of matter at all? OR, could it be living? Probably not, just want to hear some opinions on the state of fire, because right now, I'm not sure.

I just had the best freaking idea any inventor has ever had through all of time. People say they have psychokinetic powers, the ability to move and change things with their minds. I have seen no evidence of this, but maybe it's a quality only shy people have. So, my idea for an invention is gloves that will allow the wearer to grab things from a distance, up to 50,000 pounds, and move them without touching them, or push multiple things away with a kinetic field of energy, and maybe other functions if I can think of any. However, making these will be a problem. I'm not asking for money, I'm asking if I should use electromagnetic pulses to move things or if I should try and develop a new energy type and use that. Any ideas will be widely appreciated.

It was originally written as evaluate the integral of x(squareroot(1+x) but its the same thing either way.

I was thinking integration by parts, but its not working. I don't want or need the answer I just want someone to put me on track and tell me which technique or techniques I should use. Thank you.

I have plans, I have ideas, I've got theories people haven't thought of before. All my friends think I'm crazy but I believe I can do it. So if anyone knows how to cut a hole through nothingness in the space-time contiuum around a wormhole or if anyone can afford ten BESS batteries and send them to me, I'd really appreciate it. I've got two ideas, and one will be really expensive and Hollywood-like. The other will be uninteresting, difficult, more expensive, but has a much higher chance of success.

IS there any way to redo the RC time equation for a given voltage, rat,her than a given resistance? like if you, say, doubled the voltage, the cap would charge twice as fast, but what's the equation?

using the numbers one to one hundred
how many combinations can you have

you can use any number of the numbers they can't repeat however. ie. (1,3) or (6,4,2,3,)

now suppose each number also was a, b or c
ie. 1a, 1b ,1c
you cannot use the same number twice in the combination ie. you can't use 1a and 1b in the combination
how many combinations now

I need to figure this out for an advanced biology paper.on neural connections.
my expertise is biology and not mathamatics.
