## Physics #

Interesting topics in physics:

- electrical circuits and electromagnetism in general (the use of vector calculus are really cool; I guess this is really why it was invented)
- astrophysics
- fluid dynamics

### Links and articles #

- Simulator of iceberg buoyancy based on drawing a free-form shape.
- This interesting correction to a back-of-the-envelope calculation of the legendary Richard Feynman relating to the relativistic time differential between the surface and the core of the Earth.
- This nice explanation of the maths and Newtonian mechanics involved in getting rockets into orbit and manoeuvering them through space, explained very clearly and in detail.
- An extremely well-made explanation of how internal combustion engines work.
