In about half an hour, UK pass, starting at 22:46:48, duration 394 secs, exceptionally bright, Magnitude -3.7

Some passes of the visible from the UK overnight - I'll tweet/toot warnings closer to the time

You matter! Unless you multiply yourself by the speed of light squared...then you energy -- Source unknown

If my memory gets any worse I'll be able to plan my own surprise party -- Source unknown

I still find it faintly incredible that no group of scientists has gotten together and just made a damn set of free textbooks to cover the whole standard curriculum of their field. For uni physics, you'd need, roughly speaking and allowing for bits of overlap:

1. Classical mechanics
2. Single-variable calculus
3. Electromagnetism
4. Multivariable and vector calculus
5. Statistical physics
6. Quantum physics
7. Special relativity
8. Data analysis (a text most likely used as reference in a lab course)
9. Differential equations
10. Linear algebra

Education reform went haring off into MOOCs without really contemplating the possibility of making better resources for more traditional in-person teaching.

I wonder how long it will take this police sketch artist to realize I'm describing him -- Source unknown
