Mathematicians Calculate How Randomness Creeps In
Mathematicians have figured out exactly how many moves it takes to randomize a 15 puzzle.
Why the Sum of Three Cubes Is a Hard Math Problem
Looking for answers in infinite space is hard. High school math can help narrow your search.
Mathematicians Cut Apart Shapes to Find Pieces of Equations
New work on the problem of “scissors congruence” explains when it’s possible to slice up one shape and reassemble it as another.
A Power Law Keeps the Brain’s Perceptions Balanced
Researchers have discovered a surprising mathematical relationship in the brain’s representations of sensory information, with possible applications to AI research.
Mathematicians Begin to Tame Wild ‘Sunflower’ Problem
A major advance toward solving the 60-year-old sunflower conjecture is shedding light on how order begins to appear as random systems grow in size.
How Randomness Can Arise From Determinism
Playing with a simple bean machine illustrates how deterministic laws can produce probabilistic, random-seeming behavior.
With Category Theory, Mathematics Escapes From Equality
Two monumental works have led many mathematicians to avoid the equal sign. The process has not always gone smoothly.
Why I Called It ‘Quantum Supremacy’
Researchers finally seem to have a quantum computer that can outperform a classical computer. But what does that really mean?
Solution: ‘Perfect Randomness’
Is nature inherently random or is perfect randomness just an illusion based on our ignorance?
