Solution: ‘Hanging Far Out Over the Edge’
A simple and elegant way to stack identical flat objects so that they project over an edge as far as possible.
The Math That’s Too Difficult for Physics
How do physicists reconstruct what really happened in a particle collision? Through calculations that are so challenging that, in some cases, they simply can’t be done. Yet.
How to Hang Far Out Over the Edge
What formula describes the farthest you can stack flat blocks over the edge of a table to form a seemingly gravity-defying half-bridge to nowhere?
Strange Numbers Found in Particle Collisions
An unexpected connection has emerged between the results of physics experiments and an important, seemingly unrelated set of numbers in pure mathematics.
The Devil in the Polling Data
The same problem that caused the 2007 financial crisis also tripped up the polling data ahead of this year’s presidential election.
