New Year's resolutions have always been something to beat myself up with by the second week of January. It seems perverse to set yourself up for failure right at the start of the year.

When I started doing stand-up, I resigned from my job as a maths teacher and, three days before I was due to leave, my dad passed away.

I loved stand-up, but I never thought you could do it as a job.

I used to do standup about footballers; they are easy targets because they are traditionally seen as stupid.

The science-denial machinery is a serious adversary, and it has a big advantage over real science: it does not need to win its dispute with real science; it just needs to create a public illusion that there is a dispute.

As for the forces, electromagnetism and gravity we experience in everyday life. But the weak and strong forces are beyond our ordinary experience. So in physics, lots of the basic building blocks take 20th- or perhaps 21st-century equipment to explore.

I've had various experiences where I've been called by Hollywood studios to look at a script or comment on various scientific ideas that they're trying to inject into a story.

Providing better computer science education in public schools to kids, and encouraging girls to participate, is the only way to rewrite stereotypes about tech and really break open the old-boys' club.
