Richard Feynman – The Douglas Robb Memorial Lectures – Part 1
A gentle lead-in to the subject, Feynman starts by discussing photons and their properties.

The idea of time travel makes great science fiction, but can it really be achieved? Paul Davies, Visiting Professor of Physics at Imperial College, describes wormholes in space and other ways that might allow travel into the past or future.

The main problems associated with communicating with distant space probes like Voyager 1 are investigated. The role played by diffraction in limiting the amount of power receivable on Earth is discussed. The further problems of reaching a nearby st....

A brief look at the Physics behind sending signals along cables and via geostationary satellites. An experiment to measure the speed of an electrical pulse in a cable is described and the Physics of the orbits of communcations satellites is develope....

F=ma (laws 1&2). Forces come in pairs that add to zero (3). Newton's laws apply in inertial frames of reference. Some common approximations made in applying them.
More details | Watch nowSimple harmonic motion
In simple harmonic motion, displacement, velocity and acceleration vary sinusoidally with time, but with different phases.
More details | Watch nowCircular motion
Uniform circular motion: angular displacement and velocity are introduced and centripetal acceleration is determined.
More details | Watch nowProjectile motion
Motion with uniform acceleration, such as in a uniform gravitational (or electric) field is projectile motion, analysed here with examples.
More details | Watch nowMotion with constant acceleration (kinematics)
Kinematics quantifies motion without explaining the causes of it. Here we study accelerations that are zero, positive or negative.

Standard analysis of the relativistic dynamics of scattering on a step potential leads to a paradox that contradicts the standard interpretation of a wave function in nonrelativistic theory. It is shown how is this result obtained by not being carefu....

The quantum gas is an extreme state of an ensemble of atoms when their de Broglie wave length is of the same length as the size of the container. The ways of achieving this state are described and also how its temperature is defined.
