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
if you projected light of 3 wavelengths: Red, green and blue.
of all the same intensity then it equals white?
what about if you projected 4 different wavelengths? you just added another one in?
under what condition will it appear to be white?
Thanks bob. Once I piece together all of this information I hope I can find the time to assemble some 3d Models in Maya for Educational purposes. I will probably start with modeling a linear accelerator though. I was just curious about cyclotrons because my grandfather worked on a Cyclotron at...
wouldn't you have the particles spinning for quite a while?
how are the particles accelerated?
it seems to me that this does not explain what object accelerates these particles as they make laps.
Also, on the accelerators like the LHC. Are quadrupoles the primary method for focusing the beam...
what creates the magnetic field on a cyclotron?
in all of the schematics I am looking at it just says "magnetic field points up"
like it is extremely apparent as to what creates the magnetic field.
I was thinking that a bunch of small diameter solenoids packed side by side would be the best way...
I would need it to work with wavelengths outside of the visible spectrum.
I don't need it to tell me the wavelength, but I just need to know the intensity.
I will read about bolometric thank you for the keyword.
oh yea, i did not think about that
VHF frequench = 30 MHz
wavelength = 10 m
longwave frequency = 30kHz
wavelength = 10000m!!!
10km! that is huge.
have any diffraction experiments been done with massive wavelengths like this?
I am looking for an electromagnetic field detector that can detect use to detect the intensity of wave on a grid and return the results to a computer.
the higher the resolution the better.
does anyone know where this can be purchased?
how could one be designed?
you could test this pretty easy right.
just get a wall of concrete or something and a dipole.
then set it to oscillate at various frequencies on one side of the wall.
Then on the other you put a Electromagnetic Radiation Detector and compare the levels for different wavelengths.
this would work...
