Physics, To A Dog (A poem)

To a dog, a balloon is a rock that floats.
To a dog, a lever is a perch for stoats.

To a dog, particle decay¹ is not about nooks
To a dog, gravity is just another way to puke.

To a dog, a quantum is a kibble
To a dog, a quark is to nibble.

To a dog, where the yard ends begins the cosmos
To a dog, periodic tables² iz a no-nos.

To a dog, dark matter is what cats must do
To a dog, string theory is for cats too.

To a dog, it is better to sleep
To a dog, don't tickle the heap.³

Notes
¹Bone munching
²Do not take food off the table. Periodically.
³A veiled reference to "tickling the dragon's tail" during early A-bomb research. Dogs prefer if you tickle their stomach instead.
