The bell is typically bell-shaped for two reasons, first because the circle is structurally strong and this allows bells to be struck with greater force than if the shape was flat or had sharp edges ...

The physics is actually much easier than it seems at first glance. Power generators are engines just like the everyday ones we see all around in our cars, lawnmowers, snowblowers, etc. Except for ...

The simplest way to think about it is that there is mass all around you in the center of the Earth so you get an equal gravitational "pull" from all directions. The pulls cancel out so you get no ...

Kill all the turtles on which it rests.

I found Mathematical Methods in the Physical Sciences by Mary Boas to be a very good broad book covering the basics. You'll need other books obviously but if you are looking for one book for a solid ...

Blackbody radiation for a white hot object emits the spectrum from infrared to ultraviolet. See: http://en.wikipedia.org/wiki/Black_body Graphite is a decent approximation of a blackbody radiator. ...

Ground effect is caused by the increased pressure under the wing because the vortex at the end of the wing which normally just twists behind the wingtips for long distances runs into the ground itself ...

The easiest way to think of it is this, imagine all the mass left over when a rocket has burned 85% of it's fuel. The mass of most of the tank and structure is now overkill and waste. It would be nice ...

The human retina and visual perception system of the brain display in combination what is known as "persistence of vision." The eye and brain retain a visual image for somewhere between 1/30th and 1/...

The force that you feel in a Tilt-A-Whirl is not possible in a galaxy and does not correspond to anything in our solar system. In a Tilt-A-Whirl, you are subject to two additional constraints that ...

Unless you are talking about in the very limited sense where at the molecular level some number of molecules of the tire must rub off in order to transfer a force to the car, the statement: "if the ...

Entropy and the Second Law of Thermodynamics relate to life because life is made possible by the flows of energy implicit in the second law and the selective storage and manipulation of the ...

I have found the LQG introduction references here: http://www.physicsforums.com/showpost.php?p=2868468&postcount=244 to be quite useful. Marcus is a very nice guy, knows most everything going on ...
