Short talks from University of Oxford Physics Department.
Contains episodes previously published as:
(1) 'Astrophysics: An Introduction'
(2) 'Lab, Camera, Action!': "Lab, Camera, Action! is a series of short videos presented by Dr Andrew Steele about physics, explaining basic concepts, the work done here in Oxford, and even some experiments to try at home. These engaging tutorials cover a range of topics from spectroscopy, superconductivity and the transit of Venus in a clear, accessible way which will appeal to science enthusiasts everywhere."
(3) 'Physics Flash Talks': 'A showcase of research at Oxford Physics through exciting 10 minute presentations delivered by graduate research students. The topics span the breadth of research at Oxford and include topics such as climate change, exoplanets, magnetism, the higgs and quantum computers.'
Plants, Photosynthesis, and Solar Energy
The planet is in trouble; fossil fuels are being depleted and are contributing to global warming. Plants, however, have been directly harnessing solar energy for as long as they have existed.

Are we still in the dark about Dark Matter?
Kathryn boast gives a flash talk discussing what we already know about dark matter, and what we still have to find out about it. There is quite a lot of conclusive evidence for the existence of dark matter, but we still have very little idea of what it actually is. Kathryn Boast takes you on a guided tour through one of the biggest mysteries in physics, and shows how physicists are trying to shine a light on dark matter and show you some of the kits that she is helping to develop.

Einstein's Greatest Blunder
Albert Einstein is one of the greatest scientists to ever live, and even he made mistakes, as Luke Jew explains - A comforting thought for all of us! This great mistake was about the astrophysics that will ultimately determine how our universe will end.

Quantum Measurement and Control: How to Roll a Six Everytime
In this flash talk Wojciech Kozlowski discusses the bizarre properties of measurement and how we can harness its probabilistic nature to produce results. Quantum mechanics is currently our most precise physical theory. Whilst we do not have many strictly quantum technologies yet, quantum theory is necessary for our understanding of the world around us, from the basic constituents of matter to semiconductors in electronic devices, and even biological processes such as photosynthesis. Measurement and its probabilistic nature lie at the very heart of quantum mechanics which prompted Albert Einstein to say his famous words "God does not play dice with the universe!"

Space - The Ultimate Laboratory
What can space teach us about the laws of physics? Space is huge and complicated. This is a challenge, but also gives us the ultimate physics lab. Francesca Day explores this further. Light from the beginning of the universe is hidden in the night sky. In space we can see physics at much higher energies and over much larger distances than we could ever manage on Earth. Space is also a great place to look for new particles – it produces and accelerates them for us and then drops them right on our heads. I will talk about how we can use space to discover new physics and new particles.
