হিগস বোসন

হিগস বোসন দিয়ে মৌলিক কণিকার ভর ব্যাখ্যা করা যায় । ব্যাপারটা ঠিক বুজতেছি না । মৌলিক কণিকাসমূহের তো নিজস্ব ভর আছেই ।

Re: Prove me wrong

Avik bhai, I am not sure but as far as i can remember in your book "Mathescop" i have read that , \[0^{-1}= 0\]

but in this discussion I have got that , \[0^{-1}\] is undefined ....Please make it clear...

Re: Prove me wrong

I expected this answer...now see, if
\[0^{-1}= \frac{1}{0}\]
then,
\[0 = 0^{1}=0^{2-1}=\frac{0^{2}}{0^{1}}=\frac{0}{0}
so, \frac{0}{0}=0


\]
but 0/0 is undefined..... I am looking for another perfect answer....

0^0 = 0^{1 - 1} = 0^1.0^-1 = 0.0 = 0

I can't get what and where is the mistake ...can anyone help me??
