Couldn't make it to the last Science Series lecture? Did you like a lecture so much that you just had to see it again? Not to worry! Past lectures are now available on demand!
The Large Hadron Collider at CERN, the European Center for Nuclear Research, is the world's largest and most energetic particle collider. It began operating in 2009, and since that point approximately 2,000 papers have been published based on this data. Dr. LeCompte will attempt to put this into context and will discuss the relevant ideas and themes and whether the LHC data supports or refutes them. Particular attention will be paid to what the LHC is telling us about the non-trivial nature of the vacuum and some of its more interesting features.

Dr. Thomas LeCompte - Argonne National Lab
Quantum physics, the science of extremely small things like atoms and subatomic particles, is one of the best tested theories in the history of science, and also one of the most bizarre. Many of its predictions - particles that behave like waves, cats that are alive and dead at the same time, objects that pass through barriers as if they weren't even there - seem more like science fiction than science fact. In this talk I'll explain the reality behind some of the stranger aspects of quantum physics, and why it is so important that even dogs should know about it.

Dr. Chad Orzel - Union College
Since ancient times, humans have inquired about what makes up the world around them. In antiquity, the Greeks believed the world to be made up of earth, water, air, fire and the aether. Today, researchers at Jefferson Lab study quarks and gluons: what we now believe to be the fundamental building blocks of the atomic nucleus. Jefferson Lab's research on the building blocks of matter will be presented along with a discussion about why you should care.

Particle physics shares with other basic sciences the need to innovate, invent and develop tools, techniques and technologies to carry out its mission to explore the nature of matter, energy, space and time. The story of invention in particle physics and the interplay between different fields of science and society will be illustrated in this colloquium. At the same time, particle physics, and curiosity driven fundamental research in general, that could advance scientific discovery and accelerate the pace of innovation...

On July 4th, 2012, the ATLAS and CMS experiments operating at the CERN Large Hadron Collider (LHC) announced the discovery of a new particle compatible with the Higgs boson (hunted for almost 50 years), which is a crucial piece for our understanding of fundamental physics and thus the structure and evolution of the universe. This lecture describes the unprecedented instruments and challenges that have allowed such an accomplishment, the meaning and relevance of this discovery to physics...

Dr. Fabiola Gianotti - European Organization for Nuclear Research (CERN)
Paper or plastic? Gasoline or electric cars? Ethanol or gasoline? Local or imported food? We are constantly bombarded by environmental questions and by contradictory answers from "experts." This talk will show how you can cut through the fog of numbers to answer these questions for yourself, not precisely, but good enough. We will cover the principles of estimating, introduce the "Goldilocks" categories of answers, and then look at some of the big (and small) environmental questions of our time.

Dr. Lawrence Weinstein - Old Dominion University
The world around us is made of atoms. Did you ever wonder where these atoms came from? How was the gold in our jewelry, the carbon in our bodies, and the iron in our cars made? In this lecture, we will trace the origin of a gold atom from the Big Bang to the present day, and beyond. You will learn how the elements were forged in the nuclear furnaces inside stars, and how, when they die, these massive stars spread the elements into space.

Dr. Edward Murphy - University of Virginia, Department of Astronomy
From a research path that includes a little bit of rocket science, under sea measurements, radiation detection and measurement, space experimentation and two expeditions to the Antarctic, Mr. McKisson brings a different view of how much physics most people already know from observing the world around them. With a minimal amount of math, attendees will learn a little of the history of physics and may discover that they know more than they thought about what some view as an inscrutable subject.

Mr. Jack McKisson - Jefferson Lab, Detector and Imaging Group
Very little data of any kind exists from the early spring in the Arctic. The reason? It's extremely cold and that makes it difficult to survive, let alone conduct science. From March through the end of April, 2011, scientists from around the world braved temperatures of -48°C in the high Canadian Arctic in the name of science. At the Catlin Arctic Survey's floating 'Ice Base' off Ellef Ringnes Island, Dr. Victoria Hill was investigating...

The recent earthquake may have you wondering what other surprises Virginia's geology may hold. Could there be a volcanic eruption in Virginia? Probably not today, but during the Eocene, about 35-48 million years ago, a number of mysterious eruptions occurred in western Virginia. This talk investigates the possible origins of these eruptions, and what they can tell us about the crust and mantle underneath Virginia.

In 1946, physicist Robert Wilson first suggested that protons could be used as a form of radiation therapy in the treatment of cancer because of the sharp drop-off that occurs on the distal edge of the radiation dose. Research soon confirmed that high-energy protons were particularly suitable for treating tumors near critical structures, such as the heart and spinal column. The precision with which protons can be delivered means that more radiation can be deposited into the tumor...

The universe is dark and mysterious, more so than even Einstein imagined. While modern science has established deep understanding of ordinary matter, unidentified elements ("Dark Matter" and "Dark Energy") dominate the structure of the universe, its behavior and its destiny. What are these curious elements? We are now working on answers to these and other challenging questions posed by the universe with experiments at particle accelerators on Earth...

Within a decade of adding a "Cosmological Constant" to his triumphant General Theory of Relativity in 1915, Einstein denigrated the addition as his "greatest blunder." In the last decade, however, new observations have led to a revolution in cosmology and a rethinking of Einstein's alleged blunder and its implications for understanding nature and life. In this World Year of Physics Lecture Series talk, Lawrence Krauss, director of the Center for Education and Research...

Did you ever wonder how a Boeing 747, weighing 910,000 lbs at takeoff can possibly get off the ground? Or, did you ever wonder how airplanes fly upside down? Why is there a "backside of the power curve?" What makes a wing efficient? These questions can be answered when lift is developed in terms of Newton's laws. A Newtonian description of lift gives an intuitive feel for how airplanes fly, without the need for complicated analysis or approximations...

In his youth, Dr. William Bertozzi, an MIT professor who has long been a leader in experimental nuclear physics using beams of electrons, carried out an experiment in which he explored the relationship between the velocity of electrons and their kinetic energy by measurements over a range of accelerating voltages between 0.5 MeV and 15 MeV. The kinetic energy is measured using calorimetry and the velocity is measured by time-of-flight. This educational film, made in 1962, documents the experiment...
