Byron

When Newton saw an apple fall, he found
In that slight startle from his contemplation —
'Tis said (for I'll not answer above ground
For any sage's creed or calculation) —
A mode of proving that the Earth turned round
In a most natural whirl, called “gravitation“;
And this is the sole mortal who could grapple,
Since Adam — with a fall — or with an apple.

Man fell with apples, and with apples rose,
If this be true; for we must deem the mode
In which Sir Isaac Newton could disclose
Through the then unpaved stars the turnpike road,
A thing to counterbalance human woes:
For, ever since, immortal man hath glowed
With all kinds of mechanics, and full soon
Steam-engines will conduct him to the moon.
