A gentle lead-in to the subject, Feynman starts by discussing photons and their properties.

What are reflection and transmission, and how do they work?

Feynman diagrams and the intricacies of particle interaction.

What does it mean, and where is it all leading?

Searching for the mysterious magnetic monopole.

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.

In simple harmonic motion, displacement, velocity and acceleration vary sinusoidally with time, but with different phases.

Uniform circular motion: angular displacement and velocity are introduced and centripetal acceleration is determined.

Motion with uniform acceleration, such as in a uniform gravitational (or electric) field is projectile motion, analysed here with examples.

Kinematics quantifies motion without explaining the causes of it. Here we study accelerations that are zero, positive or negative.

A review of High Energy Particle Theory and Phenomenology at FSU

The use of gamma-ray spectroscopy to study the structure of less well-known nuclei.

Astrophysics is one of the driving forces behind the study of nuclear reactions and nuclear structure. The FSU Department of Nuclear Physics has the facilities and techniques needed to experimentally explore both of these topics. This video briefly....

A look at what was known when Newton started to develop his theory of gravitation and how he used these ideas and data to make his great forward step

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.

How extending Galileo's relativity to magnetism leads to Einstein's relativity, time dilation, length contraction, relativity of simultaneity and E=mc2 .
