Science Put Plainly
Hard ideas become usable when the words get honest. That is the work of this site. Science Plain is a collection of short explainers in primarily the physical sciences, including chemistry and physics. The pieces are written so a careful student—or a curious adult—can follow them without a textbook in the other hand.
You will find
- what a measurement actually claims
- how atoms and molecules behave in the world you already live in
- how Earth systems connect, from water and weather to ecosystems
- the difference between a number, a unit, and a guess
No jargon for its own sake. No filler. When a term is needed, it is defined in the sentence that uses it.
New pieces are added as they are finished, not on a factory schedule.
