Quantum Search, Debunked: The Truth Behind Grover’s Algorithm
Grover’s algorithm does not let quantum computers check every answer at once—instead, it offers a clever geometric shortcut that speeds up searches by a square root factor.
Holograms—No, Really
Unlike a photograph, a hologram encodes the full light field of a scene—including phase information—allowing it to recreate…
Measuring the True Scale of the Universe, Part 2
Early astronomers used planetary transits and parallax to calculate distances in the solar system and beyond—laying the foundation…
Measuring the True Scale of the Universe, Part 1
Starting with Eratosthenes’ clever calculation of Earth’s circumference using shadows and wells, early astronomers used geometric reasoning and…
LLMs, Explained
Large language models predict the next word in a sequence by analyzing vast amounts of text data and…
Geometry and Topology Go Hand In Hand
The Inscribed Square Problem, posed by Otto Toeplitz in 1911, asks whether every closed continuous loop contains four…
Does the Speed of Light Ever Change?
The slowing down of light in a material is due to the interaction of the light wave with…
Bending Light (And All of Its Intricacies)
The video involves the concept of refraction, where light slows down as it enters a medium like glass,…
Springs and Prisms Are Apparently Related
You’d think that a prism and a spring wouldn’t have much in common, but a thread traverses through…
The Problem With Subdividing Circles
Moser’s Circle Problem is a mathematical geometry problem that asks how many distinct areas a circle is divided…
