Neutrinos have been the origin of an impressive number of ‘surprises’.  We know that neutrinos have tiny masses and that oscillations are occurring spontaneously between neutrino species.  But additional new discoveries may be ahead of us and t....

The strong interactions, the forces responsible for the interactions between quarks and notably supposedly responsible for quark confinement, profited from the development of gauge theories.  In the wake of the gauge theory of weak interactions also....

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.

The UK coast is constantly being bombarded by sea waves.  There is a massive amount of power available from these waves.  Jonathan describes three different ways of generating electrical power from water waves.

A short video explaining how transistors work.  At the heart of our high-tech society with radios, mobile phones, computers and space exploration are tiny electronic components called transistors.  They have revolutionised electronics and in the pr....

A short video on solar cells explaining with accompanying information sheet. How they work and how Jonathan uses solar power at home.

With some simple circuitry and a homemade hand powered generator Jonathan makes AC and DC electricity that could be used for charging a mobile phone or attaching to a wind turbine.

Jonathan makes some simple paper windmills/turbines and experiments with a simple generator to power house hold devices such as torches, calculators and even a radio.

Jonathan shows us with a cheap and simple homemade demonstration how your mobile telephone generates radio waves in order for you to use it to communicate.  As you will see you can use this method to explore many aspects of your mobile phone!

This short video shows one of the demonstrations for the Physics SEPNet exhibition - "Who will keep the lights on?" which travelled around the southern UK from February 2009.  We describe and explain the electrical generator demonstration which Jona....

Early lighthouses used coil and wood fires before moving on to gas and then electricity powered lights.  Massive improvements took place by using a lens system around the light.  The development of the Fresnel lens brought what we now regard as the....

Light, particularly sunlight, is believed to be good for our health. Many ancient civilisations even attributed it with mystical healing powers.Renowned for his entertaining lectures, Professor David Phillips, President of the RSC, uses his expertise....

New carbon targets requires reducing emissions of greenhouse gases by 50% for 2030. This house believes that it will be impossible to meet the emissions reductions required to fulfil these obligations without the use of nuclear power.  Taking the pr....

Classical dynamics uses the concept of force for its solution. On the other hand force in quantum dynamics has no meaning and the concept of potential energy is used instead. The question is, "which one of the concepts is more fundamental?".

A series of nine lectures from Leonard Susskind who is the Felix Bloch Professor of Theoretical Physics atStanford University, and Director of the Stanford Institute for Theoretical Physics.

During the Renaissance in Venice, composers such as the Gabrieli and Moneverdi created some of their greatest masterpieces for performance in the great churches on festive occasions. But what would the music have sounded like, given its complexity an....

Sir Arnold Wolfendale FRS is Emeritus Professor of Physics at the University of Durham, and former Astronomer Royal. In 1912, Victor Hess embarked on a perilous balloon ascent and discovered the 'Cosmic Radiation', actually a beam of atomic particles....

With the start of the Large Hadron Collider (LHC) at CERN, particle physics entered a new era. The LHC will provide a deeper understanding of the universe and the insights gained could change our view of the world, and the lecture will present some o....

An unusual look at the effects that things rotating have on our everyday life.

The physics of the eye, its performance and colour vision: refraction and accommodation; photoreceptors and resolution; compromises in visual performance.

On scales much bigger than the wavelength, rays explain the behaviour of interfaces, mirrors, lenses, optical instruments, including telescopes and microscopes.

White light comprises colours in the visible spectrum. The electromagnetic spectrum. Speed of light. Young's experiment and waves. Quanta and photons.
