In search of wealth, in times of old,
But substances remained as much as they always were;
and so came to prove the great Lavoisier.
With the most primitive methods that he employed,
he proved matter can neither be created nor destroyed.
And this simple law brought to science a great revolution;
it was Lavoisier’s Law of Mass Conservation!
But even back then no theory had stated
that different forms of energy were closely related.
And another surprise came the day
“They are related indeed!” said Faraday.
And so in any form may energy reside;
energy can neither be created nor destroyed.
And this law was yet another sensation;
it was the Law of Energy Conservation!
About every law, scientists have debated,
proved and disproved each theory stated.
Thus two worlds (of mass and of energy) existed,
whose quantity of contents always persisted.
But none did realize that the two worlds were joined.
There existed a bridge, only one man could find.
Thus he derived an equation so fine,
and he was none other than the great Einstein.
