So how can one make forces mutually inclusive(that is force unification) when atuually we ofserve forces as being mutually exclusive?
Was it not Einstein's conclusion that a Force IS a Force?

Suppost you have a sphere. The inside surface of the sphere is a perfect mirror. What does the reflection on the mirror look like if an object -- say a book or a teddy bear or a pineapple -- is hovering inside the sphere at its exact center?

Is the entire mirrored interior surface of the sphere covered with a reflection? Is every point on the mirrored interior surface of the sphere reflecting a point on the surface of the object in the center?

Will there even be a reflection? There's no light source in the sphere, so do we have to assume a light source in the sphere someplace? How does that change the reflection (some points of the inner surface of the sphere will be in shadow if the light source is inside the sphere)?

Can the light source be external, e.g. a the sphere is a two-way mirror?

When wading across a stream or river for example. I want to know how the force of water varies according to its depth and velocity of flow. And are there any other factors that affect the force exerted?

Well, obviously I'm completely misunderstanding relativity here, but it seems to me that if you've got a doppler shift where there wasn't one earlier, there's got to be some change in relative velocity between the observer and the waves, Now, if an observer can change their velocity relative to light waves, then how is it that "observers will always measure the speed of light to be the same no matter what their state of uniform linear motion is"(-Wikipedia)

I remember reading a Q asking if it was possible for a human to wear a suit to produce electricity from what they do everyday (move).

I recently ran across this article…

Bob Komarechka, a geologist from Sudbury, Ontario, spends many tedious days in the field lugging rock samples and electrical instruments. Two seemingly unrelated desires—one for a pair of comfortable gel-cushioned soles, the other for an alternative to frequently changing his instruments’ failing batteries—led to an epiphany.

In May 2001, Komarechka received a U.S. patent for a shoe design that uses the rolling motion of walking to produce a steady flow of electric current. When a person steps forward, fluid is forced out of a sac in the heel through the blades of a small turbine into another sac in the toe, where the fluid is held by a check valve. When the foot rolls onto its toe, the fluid is squirted back through the turbine and into the heel. Both the turbine and a microgenerator are located between the sacs, in the center of the sole, and a socket connects a wire to electrical devices.

Using calculations based on the average person’s weight, Komarechka believes that the shoes could generate a steady three watts of electricity—enough to power a hand-held computer, a GPS device, or a radio, or to continuously recharge batteries.
No prototype exists yet, although Komarechka is waiting for replies from Reebok, Nike, and the U.S. military. “I know I can make it work,” he says. “It’s fairly straightforward.”


So now the question is, is harnessing human movement possible in the future to create energy?

(even if it only powers my batteries for my MP3 player I’ll be thrilled! Endless MUSIC!)

Leaving aside the argument of whether they are made by a divine, extraterrestrial, or even earth-centered unseen force, or are a work of pure human artistic genius, do the symbols, geometric and mathematical messages of crop circles provide any meaning to us? Can we learn anything from them? Are there any serious studies of this phenomena?

Most elevators have a 7' or 7.5' ceiling. If one could jump up just slightly just as the elevator starts its decent, will you bump your head? You would have to time it just right I'm sure. My wife says no, you won't bump your head, but I disagree.

Just for fun: Next time you get on an elevator filled with folks, make sure you're the last person to get on. When you step inside, don't spin around and face the doors. Keep facing the crowd and watch their reactions. They will all be quite nervous as you are doing something that's not usually done. I learned it in a class I attended and I tried it. It's a blast!
