I've been really getting into the Christmas mood, relaxing with a cup of coffee and all the books that arrived this week, and trying to ignore Padma's sideways looks. Things came to a head when she asked me, "If energy equals mass, why do you have so little?"
A little knowledge is a dangerous thing, and I had to remind her that the formula she referred to stood for Energy = milk times coffee squared.
However, to shield myself against any further argument, I got onto YouTube to watch the interesting docudrama "Einstein's Big Idea".
I suggest you do the same. Enjoy your milk times coffee squared!
