This Strange Wave Changed Physics Forever

Summary by Krater

The host recreates John Scott Russell's observation of solitary waves (solitons) in a canal using a kayak and e-bike, then builds a model water channel to demonstrate how non-linear wave equations explain solitons, optical solitons in fiber optics, and underwater internal waves.

Answers: What is a soliton and how do solitary waves form?

• solitons
• wave mechanics
• wave of translation
• Froude number
• linear vs non-linear waves
• optical solitons
• nerve solitons
• quantum solitons
• internal waves

What it concludes

• A soliton is a non-linear wave that maintains its shape and travels like a particle, unlike linear waves which disperse.
• Bigger solitons move faster than smaller solitons and can pass through each other by exchanging momentum.
• A soliton forms when water velocity matches or exceeds the natural speed of shallow water waves, balancing steepening and dispersion.
• Solitons occur in optical fibers as pulses of light that travel without distortion over long distances.
• Internal solitons in ocean water layers can form massive underwater waves resembling the Loch Ness monster.
