Had too much of it already??I think this blog also neds a new look. Though black is a good colour but CHANGE is really necessary. Something bright would liven up the blog.Hope to see some good interesting stuff too.

Hi frenz!!i never imagined reading about black holes would ever be so interesting, here's a question on the same;- is the statement 'black holes have infinite density' that we've learnt in the junior classes 'really' correct?? whatever be your reason, it should not include big theories by scientists. All i need u to do is to answer the question using whatever knowledge u've gained in

One exam over, and that means one less to worry about.Anywayz it was sad to see not even one correct answer for the questions I posted on the blog. I've got another question with me, but i've no hope. I dont think I will get a correct answer to this one too. here is the

Symmetry

2005-03-18T17:06:00.000+05:30

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...Can you tell me what kind of symmetry do we have in nature???

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?

Who does'nt like changes. So presenting the new look of our blog.One more thing ... As the name of the blog suggests we should try and take it to infinite limits so from here on this place is not only to "Discuss maths and solve some of the best questions" but to solve any kind of problem i.e. physics,computer programming,any other subject just BARRING CHEMISTRY !!.

Here's another nice question..... Five men and a monkey were shipwrecked on a desert island, and they spent the first day gathering coconuts for food.

hi everyone, thanks for letting me join.. Does anyone know what is 'i' to the power 'i'? Another thing.. someone asked me this question.. Spot the fallacy: d/dx (x^2)=d/dx(x+x+x+x+x+x.........x times) =d/dx(x)+d/dx(x)+.....x times =1+1+1+1+1+1+1.. x times =x but d/dx(x^2) = 2x.. How is this possible?

But the problem comes with some constraints:-

Integrate if you can
