  Physics Tip


potential energy
Potential energy is the energy possessed by an object because of its height above the ground. The amount of potential energy possessed by an object depends on its mass and its height. A roller coaster car is initially hauled by a motor and chain system to the top of a tall hill, giving it a large quantity of potential energy.
 

  Physics Quote


It is not uncommon for engineers to accept the reality of phenomena that
are not yet understood, as it is very common for physicists to disbelieve
the reality of phenomena that seem to contradict contemporary beliefs of
physics - H. Bauer

             What is Geometry?

 

Geometry is basically the study of shapes and the structure of anything. There are many kind of geometry which shall be discussed in the later half of the paper but the most important of all is the Euclidian Geometry.

 

Euclidean geometry is the kind we encounter at school, where the angles of a triangle add up to exactly 180o, parallel lines never meet, and so on.

 

In Euclidian Geometry, the position r of a point in space is given by:

r2= x2+ y2+ z2

 

Sum of angles of a Triangle as seen by Euclidian Geometry

This is the geometry that we have been learning from our childhood.

Now let us see where Euclidian Geometry is used with respect to space.

Excuse me, but much of the latter part of this article appears to be a blatant cut-and-paste of Einstein's very own article from the Thirteenth Edition (1926) of the Encyclopedia Britannica entitled "Space-Time". I can find no credit given by this author on this web site. This brings into question, in my view, the integrity of this entire article and it's author on this web site. Troubling. (cf., http://preview.britannica.co.kr/spotlights/classic/eins1.html)

This article was excellent. I am preparing some material to teach a unit on geometries to middle school teachers and this cleared up many of the problems I had in explaining the differences between Euclidian and non-Euclidian geometries to them. Thanks to the author!

instead of euclidean geometry differential geometry would've been a better option

Way too many pages to flip too...

nice article, but I didn't enjoy the formatting
