Rock in 11 Dimensions: Where physics and guitars collide
The Institute of Physics Schools and Colleges Lecture 2008. Delivered by science presenter and rock guitarist Dr Mark Lewney. Rock guitars, superstrings, 11 dimensions and the world's largest and highest energy accelerator are the prime ingredients for the loudest lecture to date. This lecture reveals how: rock guitars make their distinctive sounds; string vibrations might answer questions about the Big Bang; the LHC may let us peek into extra dimensions.

Rutherford Gold Foil Experiment - Backstage Science
Ernest Rutherford's famous gold foil experiment involves the scattering of alpha particles as they pass through a thin gold foil. It led to a better understanding of the structure of atoms. It's also known as the Geiger--Marsden experiment, after Hans Geiger and Ernest Marsden who performed it under Rutherford's supervision.

Why is glass transparent?
Professor Phil Moriarty (University of Nottingham) discusses transparent glass and energy gap.
PS MESSAGE FROM PROF MORIARTY: "I misspoke for the last sentence of the video. What I meant to say is that the photons don't have enough energy to excite electrons across the energy gap and therefore light is transmitted. What I said was precisely the opposite, contradicting everything else in the video. Apologies for any confusion caused."

Block and spring system
Hooke's Law: force exerted by a spring
Hooke's law: the magnitude of the force exerted by a spring is directly proportional to the distance the spring has moved from equilibrium.
Conservation of energy
The block slides on a horizontal frictionless surface. K is kinetic energy. U is elastic potential energy and E is total mechanical energy. While potential energy is converted to kinetic energy (and vice versa), total mechanical energy remains constant.

Garik Israelian: What's inside a star? (TED Talks)
Garik Israelian is a spectroscopist, studying the spectrum emitted by a star to figure out what it's made of and how it might behave.
Pink Floyd fans will appreciate his reference to Dark Side of the Moon: "The power of spectroscopy was actually realized by Pink Floyd already in 1973. Because they actually said that you can get any color you like in a spectrum. And all you need is time and money to make your spectrograph. "
