- From pendulum to soliton
(GIF images, texts in Japanese)
- A pendulum is a typical nonlinear system
that we encounter in our life frequently.
This article shows how the sine-Gordon equation
-- a model equation of soliton phenomena --
emerges out of this simple mechanical system.
Many faces of solitons
- Solitons can be observed in many equtions. The profile
of solitons are diverse and reflect the equation.
This article presents many faces of solitons with texts
