Science jokes.
Scientifically corny jokes involving atoms, ions, planets, chemistry, biology, and highly questionable laboratory methods.
Science gives ordinary words specialized meanings. Charge, reaction, cell, matter, phase, and space all belong to both everyday conversation and scientific explanation. A science joke creates a tiny collision between those worlds.
No peer-reviewed discoveries are reported here, but each joke has undergone a rigorous uncontrolled trial. Results consistently show elevated groaning under standard atmospheric conditions.

Why it works
Specialized meaning. People bond when they form a close relationship, while atoms form chemical bonds within molecules.
Why was the physicist’s new book so popular?
It had mass appeal.
Why it works
Specialized meaning. Mass appeal means broad popularity, while mass is also a fundamental physical property.
Why did the botanist trust the tree’s testimony?
