Hello all
I've been reading about the quantum vacuum plasma thruster. On the surface it sounds great. My question is, well, is it legitimate? I don't have the expertise to give it a yea or nea. Could someone who knows what they are talking about give me an answer. It seems like a miracle...
The idea of just droping nukes out the back to push you foward seems ludicrously primitive. Only a fraction of the blast energy would push the craft fowrard. Nuclear energy is definitely a viable option for space travel, and in my opinion the best, but bombs won't propel us. Rockets will.
My...
Personally I'd like to see them bring back JIMO, but I hate for JWST to die because of bureaucratic nonsence and poor management within NASA. I understand the need to hurl humans into space but we often forget how much we can learn just by looking and watching.
As humans learn more and more about the world and the bodies we are trapped in we have been able to meddle with our own properties. Before evolution was guided by nature, but now we have started to meddle with nature. Our evolution will be influenced more and more by us. I think the only way it...
Once you exceed the force of static friction can resist then you get kinetic friction. That is the friction on a moving object. Its coefficent is almost always less than static friction.
On a recent episode of Stan Lees superhuman they looked at a man who is super strong and can bend metal bars and cooking pans. They showed the electrical activity in one of his arms when he was bending a pan. They said he had a much stronger signal than normal people would have. Reading that...
I have always thought of space as the board that the game of life is played on. It is what we use as a refrence points to relate the elements of our reality.
I've had grasses as long as I can remember. I have always loved to look at the sky with my prescritpion sun glasses and turn my head to watch the colors and intensity change. No matter what angle I look through there is always a view of the sky. It has light polarized in many directions, from...
At my school computer science is an engineering program. And we are the only major that incorperates physics and math to describe and control systems. EE and CE have some of the physics and almost none of the math.
I understand what you mean. I am a computer science major and what I want to do the most is make avionics and computers that control unmanned aircraft.
Most control of devices is provided by electronic means. Whether it be through software or hardware it will all be done with electronics. I...
Hello all,.
I have been doing work on my brakes and now I would like to get new brake rotors. I replaced the standard brake pads with performance pads; I love them, and now I want even more. I already am going to replace the tires but I can't decide what brake pads I want.
I have...
I'd be more worried about the neutron radiation, but then again electrocution is no fun either. I would start looking at wikipedia, it generally has enough links and sources to find something good. If you feel ambitious enough you should a polywell. For some reason my mother still refers to it...
Any unbalanced moment about the ball will cause rotation. Any friction will create a moment about the ball equal to Rmg cos(θ) times the coefficent of friction. Unless the inclined plane is a wall or the coefficient of friction is zero the ball will spin.
