    Magnetic shielding using a semiconductor?

    I read an article a week or so ago talking about using a semiconductor to disrupt a magnetic field. Generally a magnetic field can be disrupted by any magnetic material in its path. Steel for a basic example can reduce the realized field on the opposite side from the magnetic field source...

    Thin ceramic plates sources / manufacture techniques?

    I need to insulate the area between two heat sinks. The gap is about 10mm, and the bottoms of the heat sinks are facing eachother with a peltier chip sandwiched in-between. However the two sinks are in separate enclosed sections, and I need to insulate the hot side from the cold side as much as...

    How to transfer cold energy instead of heat?

    How to transfer "cold" energy instead of heat? My question is pretty basic. I am looking to radiate cold with the same concept of heat dissipation. For example on a peltier thermoelectric module gets hot on one side and cold on the other. A heatsink will help dissipate the heat from the hot...

    Airflow inside a computer tower.

    I had a question and I figure you guys are the best for the task. I was wondering if theoretically you had a standard computer case, would you benefit by reducing open airspace in the case? Lets say just for example you could place a cube inside the case that doesn't touch anything, it just...

    Earths Magnetic Field and solar winds

    Since the earths magnetic field helps to protect the earth from a lot of the suns harsh treatments, do we also assume that in some degree light is also (possibly in very small fractions) also diverted by the magnetic field? If no, would it even be possible to assume that a very strong...

    Spinning Magnet Question

    Lets say we have a spherical shaped and very powerful magnet. Lets say it has a 3" diameter and has some good weight to it. What would happen if you spun the magnet at great speeds. Lets say for the sake of argument say some 300,000 RPM. Could the centrifugal for created by the spinning...

    Earths Gravity and Spinning.

    Of, so the earth has gravity because of its mass, but what does the effect of the spinning of the earth cause on gravity. Wouldn't thinking about centrifugal force make you think that the extreme speed we are spinning mixed with how far we are from center have some effect on us out on the edge...

    Math to the Moon

    I have a question for someone who may know a bit more about the calculations involved in this process. Lets say for instance you are standing on earth and somehow fly off the ground and go straight to the moon. Throughout the flight you will be experiencing different forces of gravity pulling...

    Getting something to the moon.

    This is all theoretical of course. I would like to pt together a small presentation on what it would take to get an object to the moon. For the sake of argument, we will say the object weighs 10 pounds. The shape can be determined by the most efficient shape given the method of propulsion etc...
