Symmetry

An object is said to be symmetrical if one can subject it to a certain operation and it appears exactly the same as before the operation.Any such operation is called symmetry of the object.Can you tell me the most symmetrical object??
It is also amazing that symmetry is used in Basic Laws of nature...

Hey!

I have just created a blog http://dipsites-2005.blogspot.com/
the purpose for creting this blog is that I want to submit a report to Mrs. S.Chona about the changes that that we need to bring in the school. As the Ex-secretary student's council I appeal to all dipsites who are passing out this year and those who are still studying at school to contribute their suggestions and comment on the changes that our school badly needs. Thank You

A nice puzzle

Hi...!!!
A rectangular sheet of paper is folded so that two diagonally opposite corners come together. If the crease formed is the same length as the longer side of the sheet, what is the ratio of the longer side of the sheet to the shorter side?

Uncertainty seems uncertain

Heisenberg said that the product of uncertainty in momentum and position will be greater than or equal to h/4π . Why only h/4π; why not c/8 or any other number?

Applications of Derivatives

The sum of the lengths of the hypotenuse and a side of a right triangle is given, show that the area of the triangle is maximum when the angle between them is ^π/₃.


I'm also testing Infinite Infinity with this question and seeing what the response time is, so as to know whether it's more practical to use this website or to call up say Rungta and ask him what the solution is.
