Welcome to Duffell.org

There has been a little restructuring for security purposes; if you want to see the rest of the site, you'll have to change the url directly, rather than using the standard links.

In the meantime, enjoy my latest physics text updates:

[Chapter 1] Review of Manifold Concepts
[Chapter 2] Overview of Group Theory
[Chapter 3] Lie Groups
[Chapter 4] Fiber Bundles

[ Vector Primer ] A primer on vectors and covectors

[ Kaluza ] Observations on Kaluza-Klein Theory
[ GRHD ] Numerical General Relativistic Hydrodynamics
[ QFTCST ] Quantum Field Theory in Curved Spacetime

That's all for now.

∇ • E = ρ/ε₀
∇ × E = -dB/dt
∇ • B = 0
∇ × B = μ₀ J + dE/dt
