When being beautifully wrong leads to discovery
Kepler's initial geometric theory led to the discovery of planetary motion laws.
Why the ancient Greeks rejected heliocentrism
Aristarchus proposed a heliocentric model before Copernicus, but it was dismissed due to lack of observable stellar parallax.
How to estimate the distance to the sun
The video explains how ancient Greeks estimated the distance to the Sun using the phases of the Moon, particularly focusing on the Half Moon phase.

Measuring the earth with Terence Tao
An Arab mathematician in the 10th century accurately measured the Earth's radius using trigonometry.
The topology of two-note chords
The video explains how two-note chords can be represented on a Möbius strip by considering unordered pairs of points on a circle.
The space of all musical intervals
The video explains how a Möbius strip mathematically represents unordered pairs of points on a loop, akin to musical intervals.
The barber pole optical mystery
The video explores the optical phenomenon of colored stripes in a dense sugar water mixture when polarized light is shone through it, explaining the twisting of light polarization and its dependence on light frequency.
Thinking through double slits
The double-slit experiment demonstrates wave interference patterns using coherent light sources.
This open problem taught me what topology is
