doesn't a lot of power have to be used to run the electromagnets that lift the entire weight of the train?
It seems that a maglev train would be highly inefficient, but very quiet, fast and smooth.
Can somebody verify this?
because in a train with wheels, the lift is provided by the contact of...
is it just me or is the math department lame.
Why do we need so many contradicting words for the same thing
correct me if I am wrong
"non-singular"="One single trival solution"= "invertible"
"singular" = "many solutions" ="not invertible"
from my experience I could not even notice any time.
Perhaps my enclosures are small in comparison to yours.
I would say perhaps 3 cubic meters on the inside of a 6 in pipe.
Does it propagate faster because of the vacuum?
Because it does not seem like the pumping would be making much of an air...
I thought the conclusion was that we don't have a unified theory that unites gravity, Electromagnetic, and the strong and weak forces.
All of the equations we have have problems.
Doesn't this leave room for potentially having control of gravity in the future?
I really find it hard to believe Gravity is unstoppable.
It seems every force must propagate over some medium.
We learned that electromagnetism is and now we know how to contort it.
Can't we contort gravity?
but perhaps I don't know enough relativity and I am saying something stupid.
I am trying to figure out how Helium Leak Detectors work.
If a leak detector is pumping on an enclosure that is at a low pressure, the detector will detect helium leaking into the system instantly as far as my human senses can tell.
The helium will propagate 4 meters in a time so small I can't...
Does anyone know where I can get physics and robotics supplies?
Where can I buy quadrupoles?
Lithium Ion batteries
good DC motors
Motors that can go to specific degree measures and stop
small computers built to be onboard devices
