Short explainers of the science on the plates, and guides for choosing one. New pieces with every series.
The ocean in layers, from the sunlit zone to the trenches, the animals that had to invent light to live there, and the century of machines built to follow them down.
A crystal's shape is its lattice showing through. How habit, cleavage and growth rate decide what pyrite, fluorite, bismuth and native copper look like, and what euhedral means.
What makes a thunderstorm severe, how a supercell starts to spin, why a hurricane's eyewall carries the strongest sustained winds of any storm, and the coastal warning flags that signal the wind.
Heat a gas and it emits a few precise colors, not a rainbow. Here's the physics (energy levels, photons, the Balmer series) and why every element's line pattern is unique.
A phylogenetic tree is a picture of ancestry. Here's how to read one: tips, nodes, sister groups, clades, the misreadings to avoid, and where fossils fit.
