When Albert Einstein said E equals MC squared.
I thought that he was being silly.
But when I found the real meaning out.
It was actually quite tricky.

When Brahmagupta introduced negative numbers,
I thought that he was a pessimist.
But when I was told that it was a number below zero,
He was immediately a genius.

These smart people contributed to our daily life,
And I would like to say thanks.
For using YOUR intelligent brains,
To OUR lives a piece of cake.
