William Thomson, Lord Kelvin, was born #OTD in 1824. Kelvin is largely responsible for the modern formulation of thermodynamics. The absolute temperature scale, where thermal motion ceases at 0K, is named in his honor. In awe at the scale of this lord. Absolute (temperature) unit. 🧪

That's one of three typographic jokes I know.

My students were surprised to learn that the photon is massless. They were like, "0mg!"

So the photon is the new "0mg!" particle 😆
