A physicist grows snowflakes that look like twins
Kenneth Libbrecht controls temperature and humidity so neighboring ice crystals develop almost matching shapes. In a cloud, different paths give crystals…

Admitting that some equations are unprovable
A mathematical rulebook can be consistent yet unable to prove every truth it can describe. If it is powerful enough to handle basic arithmetic, there are…

Absolute zero stops all movement
Absolute zero is the point where there is no more thermal energy left to remove, not a command that makes every particle freeze motionless. Quantum rules…

Assigning complicated dead latin names to extremely tiny bugs
A bug can have different common names in different regions, which gets awkward when scientists compare notes. A scientific name gives the species one shared…

Measuring radioactive decay to figure out how old dirt is
Some atoms in a sample change into other atoms at a predictable rate. Scientists measure how much of the original isotope remains and how much it has turned…

digits that refuse to be divided evenly
A hash table with a prime number of slots can spread keys more evenly with some ways of assigning them to slots. Because a prime has no factors beyond 1 and…

Quicksand rapidly sinks expectations
Quicksand is waterlogged, unstable ground, not a bottomless pit. Its mixture can support you partly, but struggling hard stirs the sediment and makes it…

Scientists name tiny flies after celebrities—and rivals
A scientific name can honor someone—or preserve a grudge. Its second part gives taxonomists room to Latinize a celebrity’s name or make a pointed tribute to a…

Schrödinger's cat was a challenge, not a pet theory
The imagined apparatus links a cat's fate to a radioactive atom. Applying quantum superposition to the whole setup produces the famous alive-and-dead…

Infinite monkey theorem mathematically entirely writes pure gold
Give a typist endless attempts, and even a wildly unlikely passage can eventually appear by chance. That is the infinite monkey theorem: each stretch of…

Digging up old rocks to guess ancient geographical events
Even after a river disappears from the surface, its channel can remain buried like a fossilized path. Different sediment layers and grain sizes mark where it…

Why you memorize capitals you'll quickly forget
Cramming puts a capital in front of your eyes again and again, but familiarity can fool you into thinking you’ll remember it later. Close the notes and try to…
