The study of motion is not all there is to physics. By the 18th century, scientists were delving into the relationship between the two phenomena. Today, electromagnetism is known to be responsible for the chemical interactions of atoms and molecules and all of modern electronic technology.

The uncopyability of quantum information raises the possibility of quantum cryptography - an absolutely secure method for transmitting a coded message. This lecture tells how to do it, noting that a handful of banks and government agencies already use quantum cryptography to ensure the security of their most secret data.

Learn how different materials vary in their ability to absorb heat. This factor is called heat capacity, and it provides a crucial way to correlate energy flow with temperature. Study the heat capacity of various materials, and see how quantum effects reduce heat capacity at very low temperatures.

Along with relativity, Einstein's major contributions to physics include his proof that light is made up of discrete quanta, an insight that led to the quantum revolution. Retrace his route to this key discovery. As with relativity, his genius was to break out of the classical mode of thinking about light and matter, going wherever experiment, logic, and mathematics led him.

Study the fusion reactions that take place inside the Sun. First, consider the formidable barrier that hydrogen nuclei must overcome to fuse into helium. Then, see how the mass and temperature of a star govern the types of reactions it can support. One product of stellar reactions is neutrinos, ghostly particles that pass through the Earth (and us) in colossal numbers.

Bring together all the concepts studied so far to gauge how close physicists are to a theory of everything. Focus on the shortcomings of the standard model. Then zero in on two burning questions: Why is the mass of the Higgs boson so low, and why does matter predominate over antimatter?

Description
Einstein spent the last decades of his life searching for a unified field theory that would unite general relativity with Maxwell's theory of electromagnetism. But by then, quantum theory had superseded Maxwell's work, rendering the entire exercise futile. See how this quest has nonetheless stimulated ideas for unification in proposals such as string theory.

The interferometer from the previous lecture serves as a test case for introducing the formal math of quantum theory. By learning a few symbols and rules, you can describe the states of quantum particles, show how these states change over time, and predict the results of measurements.

Take a behind-the-scenes tour of the Thomas Jefferson National Accelerator Facility in Newport News, Virginia, where Professor Weinstein and his colleagues use high-energy electron beams to probe the structure of the nucleus. Dr. Weinstein also explains other types of particle accelerators and their purposes, including the Large Hadron Collider in Europe.

Continue your tour of Jefferson Lab by learning how scientists design an experiment, get it approved, run it, and then analyze the results. Discover why interpreting the outcome of nuclear collisions is like reconstructing car crashes. One tool relies on the shock wave produced by particles moving faster than light, which is possible in mediums other than a vacuum.

Take a deeper step into the quantum world, observing how the theory of quantum electrodynamics, or QED, unites quantum mechanics with special relativity. Discover that the handy sketches of subatomic behavior called Feynman diagrams (named after physicist Richard Feynman) are really equations in disguise.

Trace the growth of physics from philosophy, as questions about the nature of reality got rigorous answers starting in the Scientific Revolution. Then, see how the philosophy of physics was energized by a movement called logical positivism in the early 20th century in response to Einstein's theory of relativity. Though logical positivism failed, it spurred new philosophical ideas and approaches.

Physics is a mathematical science. But why should manipulating numbers give insight into how the world works? This question was famously posed by physicist Eugene Wigner in his 1960 paper, "The Unreasonable Effectiveness of Mathematics in the Natural Sciences." Explore proposed answers, including Max Tegmark's assertion that the world is, in fact, a mathematical system.
