The Universe is a strange place

About the Lecture Perhaps the universe is not so much strange as brimming with lovely paradox. The search for such beauty seems to lie at the heart of Frank Wilczek’s work. Twentieth century physics, from Einstein through Wilczek’s own Nobel Prize-winning efforts, involves demonstrating the existence of a topsy-turvy reality: for instance, that such sub-atomic particles as quarks and gluons, which have little or no mass, “orchestrate themselves into not just protons and neutrons but you and me,” according to Wilczek. “How is it possible to construct heavy objects out of objects that weigh nothing?,” he asks. Only by “creating mass out of pure energy.” These particles are essentially “excitations in otherwise empty space.” Says Wilczek: “That suggests something …beautiful and poetic: the masses of particles are not like, or similar to or metaphorically suggested by—they are the tones or frequencies of vibration patterns in dynamical voids.” The theory of quarks and gluons and the strong interaction accounts quantitatively for “the mass of protons, neutrons and ultimately you and me and everything around us.” But physics has not yet squared away all aspects of the universe. Wilzcek says that “in cosmology, we meet our match, and don’t know what’s going on.” This is because scientists can’t account for much of the mass in the cosmos. 70% of this mass is in “dark energy,” which is pushing the universe apart. Wilczek hopes that explanations for the dark stuff will emerge through improving equations, unifying theories of different interactions and extending their symmetries. “Beautifying equations leads not to ugly consequences but beautiful surprises,” he concludes.

Einstein Gravity and the Expanding Universe

http://www.myspace.com/acorvettes Scientific understanding is always subject to change. Not long after Einstein proposed the cosmological constant, scientists observed that the universe was much bigger than previously thought; the astronomer Edwin Hubble concluded it was, in fact, expanding. Faced with this knowledge, Einstein renounced his own idea, calling it his "biggest blunder." Though Hubble's new findings were widely accepted, scientists now faced new questions: If the universe was so big and continuously expanding, what was driving expansion? And shouldn't the force of gravity at least be slowing it down?

3. Newton's Laws of Motion

Fundamentals of Physics (PHYS 200) This lecture introduces Newton's Laws of Motion. The First Law on inertia states that every object will remain in a state of rest or uniform motion in a straight line unless acted upon by an external force. The Second Law (F = ma) relates the cause (the force F) to the acceleration. Several different forces are discussed in the context of this law. The lecture ends with the Third Law which states that action and reaction are equal and opposite. Complete course materials are available at the Open Yale Courses website: http://open.yale.edu/courses This course was recorded in Fall 2006.

He is best known for his eponymous laws of planetary motion, codified by later astronomers based on his works "Astronomia nova", "Harmonices Mundi", and "Epitome of Copernican Astrononomy". They also provided one of the foundations for Isaac Newton's theory of universal gravitation. During his career, Kepler was a mathematics teacher at a seminary school in Graz, Austria, an assistant to astronomer Tycho Brahe, the court mathematician to Emperor Rudolf II, a mathematics teacher in Linz, Austria, and an adviser to General Wallenstein. He also did fundamental work in the field of optics, invented an improved version of the refracting telescope (the Keplerian Telescope), and helped to legitimize the telescopic discoveries of his contemporary Galileo Galilei. Kepler lived in an era when there was no clear distinction between astronomy and astrology, but there was a strong division between astronomy (a branch of mathematics within the liberal arts) and physics (a branch of natural philosophy). • http://en.wikipedia.org/wiki/Johannes_Kepler .

Stephen Hawking: Master of the Universe (Part 1 of 10)

In his post as Lucasian Professor of Mathematics at Cambridge University, he counts Sir Isaac Newton (1642--1727) amongst his predecessors. And he was born 300 years to the day after the avant-garde astronomer, Galileo Galilei (1564--1642). Following a devastating diagnosis of motor neurone disease in 1963, Hawking was given two years to live. Yet 44 years later, he still hopes to solve the big problem of physics, that of unifying quantum mechanics and Einstein's theory of relativity. Doing so will produce a set of laws that will explain everything in the universe, including how it all began - a breakthrough aptly dubbed the 'Theory of Everything'. Hawking felt that he was on the brink of this breakthrough a long time ago. When he published his surprising best-seller 'A Brief History of Time' in 1988, he expressed a certainty that the Theory of Everything was imminent. However, twenty years later, it still eludes Hawking and the scientific community. Frustratingly, Hawking's condition is worsening. His only way of communicating now is through one cheek muscle. Will he find the theory before it is too late? This two-episode documentary from the UK's Channel 4 is both a portrait of Hawking and an attempt to explain his work to non-scientific types. It conveys the basics of quantum mechanics and the theory of relativity in an easy-to-understand manner and does very well to acquaint viewers with Hawking's extraordinary life and character. A thoroughly enjoyable, inspiring and enlightening series!

Carl Sagan reads from Pale Blue Dot - Galileo

Galileo Galilei (15 February 1564 -- 8 January 1642) was an Italian physicist, mathematician, astronomer, and philosopher who is closely associated with the scientific revolution. His achievements include the first systematic studies of uniformly accelerated motion, improvements to the telescope, a variety of astronomical observations, and support for Copernicanism. Galileo's experiment-based work is a significant break from the abstract approach of Aristotle. Galileo is often referred to as the "father of modern astronomy", as the "father of modern physics", and as the "father of science". The motion of uniformly accelerated objects, treated in nearly all high school and introductory college physics courses, was studied by Galileo as the subject of kinematics.
