| 2014-Jul-07 • 9 minutes 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 prob... |
| 2014-Jul-07 • 10 minutes 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 wi... |
| 2014-Feb-03 • 4 minutes Lab, Camera, Action: Tides The Bay of St Brieuc in Brittany has one of the largest tides on Earth.

| 2013-Dec-13 • 12 minutes The Physics of the Violin Jesse Liu, winner of the the departmental Speaking Competition for undergraduates, gives a short talk on the physics of a violin. The violin and elastic band are both string instruments. Yet what is it about the first that allows it to produce sounds many would regard as beautiful? I'll explore the physics behind music and the violin to illuminate this intersection of art and science.

| 2013-Dec-13 • 13 minutes The coldest place in the Universe Tiffany Harte, Oxford Physics, discusses absolute zero temperatures and how by cooling atoms in a lab we can aim to replicate the coldest place in the Universe. I will be discussing how we cool atoms to create the coldest place in the Universe in the middle of a lab, and the fascinating states that emerge from these ultracold gases. We will look at cooling using lasers and evaporation, and see how the Highland Fling can explain giant quantum states. Creative Commons Attribution-Non-Commercial-Share Alike... |
| 2013-Dec-13 • 9 minutes Heart of Darkness: The Interplay of Galaxies and Dark Matter A short flash talk from Peter Hatfield, Oxford Physics, who discusses the origins of the galaxies we see in our night sky and the mysterious nature of dark matter. Galaxies are huge clusters of hundreds of billions of stars - the Milky Way is our galaxy, itself just one of many billions more. But even these are diminutive compared with the sea in which they swim, dark matter, an unknown substance we cannot see with our telescopes. We will look back in time over more than half the age of the Universe to see ... |
| 2013-Dec-12 • 13 minutes Superconductivity -- alchemy for the 21st Century? An exciting talk and demonstration about superconductivity and its potential practical applications by Ben Williams, Oxford Physics. Superconductivity is a weird property of some materials that has exciting applications both in the lab and outside, in new technologies. The only problem is, we don't quite know what makes superconductivity work! In this talk, you'll see superconductivity in action and find out how, just like modern-day alchemists, physicists are looking to turn the mundane into the magical! C... |
| 2013-Dec-12 • 10 minutes Sea Ice Growth: Mushy layers, Convection and Brinicles Joe Hitchen, Oxford University Physics Department, describe the different stages of sea ice growth and the formation of hollow tubes of ice in the ocean known as brinicles. Every year, millions of square kilometres of the Arctic ocean freeze over as sea ice forms but this growth is controlled by processes on the scale of millimetres and centimetres. At this scale, sea ice is not a pure solid but a mixture of ice crystals and concentrated brine known as a "mushy layer". I will describe the different stages o... |
| 2013-Dec-12 • 11 minutes Matter, Antimatter and The Mystery of Existence In this talk Nazim Hussain, Oxford University, will provide an introduction to matter and antimatter and the interplay between them. As far as we can tell, our universe is filled with galaxies and planets (and people) all of which are made of matter. But, our universe could have been absolutely empty with nothing in it at all! In this talk, I will provide an introduction to matter and antimatter and the interplay between them. I shall also explain how the fact that we live in a universe filled with matter i... |
| 2013-Jun-04 • 12 minutes How to find a Higgs boson The discovery of the Higgs boson last summer is widely regarded as one of the most important scientific discoveries of our time. This talk will take you on a quick journey describing why we were searching for this elusive particle, and the experimental challenges involved in finding it. |
| 2013-Jun-04 • 13 minutes What is a Quantum Computer? How does a quantum computer work? Why is a quantum computer so much better than a traditional computer?

| 2013-Jun-04 • 13 minutes Masters of Nature? - The physics of trying to control the climate The Earth's climate is changing; but what are we doing about it? The frustration felt all around the world at the inability to agree a meaningful deal on global carbon dioxide emission leaves people looking for alternatives. Do we have the ability to manipulate our planet's climate to prevent the effects of global warming? If so how? What would be the consequences of attempting to do so? Understanding the physics of the Earth's climate is essential to answering these questions. Using the state-of-the-art c... |
