A magnetic tunnel junction is a device with two magnets separated by a very thin non-magnetic barrier. The two magnets can be aligned parallel or antiparallel. The electrical resistance of this devices depends on the alignment. This video illustrates....

Jonathan talks to a real exoert about the science of balance.

Joining Philip Schlenoff is Dr. Jeff Owens, from the Physics department at Florida State University, to answer some physics and astrophysics-related questions!

The discovery of the Higgs boson at CERN’s LHC accelerator in 2012 by the ATLAS and CMS collaborations was the culmination of a decades-long search that had started in 1964 with the proposal of this unique particle, a signature of the origin of the....

This video shows a terrific selection of superconducting demonstrations and explanations.

30-minute lecture about the physics of hyperfine interactions, and about how to calculate hyperfine interactions by the WIEN2k DFT code

Most of the data we generate and receive (whether emails, tweets, videos or mobile calls) are now carried by optical fibres, which use light to transmit vast quantities of information over trans-oceanic distances. The use of hundreds of wavelengths ....

Using a data-logger to analyse the performance of a longboard.

A few (surprising?) thoughts on how the wheels on a longboard or skateboard actually move.

Jonathan describes his adventures with a longboard and some different methods of making a speedometer for it.

Abbie describes why bridges must be designed to counteract the effects of unwanted vibrations.

Physics' students Rosie & Carine explain the physics behind concert hall acoustics.
