David Tong: Explaining Science
I regularly speak at events for the general public where I try to
get across the wonder and beauty of our Universe and our current attempts
to understand it. I'm happy to talk on cosmology, particle physics, quantum
physics, string theory and anything along similar lines.
In recent years, I've been lucky enough to talk at venues that range from the Royal
Society, to the Tate Gallery, to the Hay festival and rock festivals such as lattitude and wilderness. I've
also had lots of fun working with the wonderful people at
Salon London.
Below is a collection of tv and radio recordings, together with some essays and presentations.
Quantum Field Theory
A Friday Evening Discourse at the Royal Institution describing quantum field theory.
Mathematics
The LMS Popular Lecture 2017: The unreasonable effectiveness of physics in mathematics.
String Theory
A discussion of string theory for Cambridge TV
A Day in My Life: Solitons and Baths
This was a one of four "Physics Lives" films commisioned by the Institue of Physics. Collectively they won a British Universities Film and Video Council Award. Which is a little like an oscar. Sort of.
