Who turned out the lights?

I feel it would be inexcusable to let a total eclipse of the sun pass without comment on a physics blog. This is especially true since I am one of the lucky people who have seen a total eclipse – in my case the 1999 eclipse that scythed across Europe. There will no doubt be millions […]

Equation of time strikes again

Horrible…dark…mornings…..Can’t….get….out…of…bed…….

Unfortunately, we can’t say the same about the mornings.  This is the equation of time kicking into play again – the darkest morning […]

Also par for the course, regrettably, is seeing the same mistakes made time and again from students. And the biggest and simplest mistake of them all […]
