The Spacetime Metric

Courses

Go deep on one idea, or climb the whole path.

Five drill-downs take a single idea from a picture anyone can hold to the research frontier. The 36-course path climbs six levels, from first principles to research preparation.

Measured physics

The Josephson Junction: where quantum phase becomes an engineering variable

A thin gap between two superconductors lets a current flow with no voltage, turns a voltage into a perfectly tuned oscillator, and defines the volt. It is also the building block of the 'gaser' and of every superconducting quantum computer.

The Vector Potential: the field behind the fields

From a flow map anyone can picture, to the Aharonov–Bohm effect, to the phase-controlled matter beam Charles Chase calls the secret sauce.

The Metric Tensor and Warp Bubbles: how spacetime is measured, and how it might be shaped

Every ruler and every clock in the universe reads from one rulebook: the metric. General relativity says matter and energy rewrite that rulebook, and every test agrees. A warp bubble is a page of the rulebook nobody has written into reality yet — and a research programme is now trying.

Quantum Phase and Coherence: the variable behind lasers, superconductors and the matter-wave beam

Phase is only where a wave's crest is right now. Get enough waves to agree on it and you get a laser, a superconductor, a condensate — and the beam Charles Chase is trying to build.

The Zero-Point Field and the Casimir Effect: how empty space pushes

Pump out every atom, cool the walls, shut out the light — and two mirrors in the box are still pushed together. The formula contains no property of the metal at all. This is the measurement the whole field is built on.
