Film biography of Gregor Mendel (1822-1884), the Moravian monk who became the father of modern genetics through his study of pea plants. One of a series of medical history films by J. Lee Sedwick, M.D., F.A.C.S., Clinical Professor of Surgery, East Carolina University, and Larry Gardner, President of Digifonics, Inc.

"What Darwin Never Knew" offers answers to riddles that Darwin couldn't explain. Breakthroughs in a brand-new science—nicknamed "evo devo"—are linking the enigmas of evolution to another of nature's great mysteries, the development of the embryo. NOVA takes viewers on a journey from the Galapagos Islands to the Arctic, and from the explosion of animal forms half a billion years ago to the research labs of today. Scientists are finally beginning to crack nature's biggest secrets at the genetic level. The results are confirming the brilliance of Darwin's insights while revealing clues to life's breathtaking diversity in ways the great naturalist could scarcely have imagined.

Explains the formation of a covalent bond.

Describes and explains geometrical isomerism in non-cyclic alkenes.

Clark College Tutoring and Writing Center tutor Joey Smokey explains molecular shapes, introducing the concepts of electron geometry and molecular geometry. Joey provides images and descriptions of the five main molecular shapes: tetrahedral, trigonal planar, linear, bent, and trigonal pyramidal.

To see how energy stitches the cosmos together, and how we fit within it, we now journey through the cosmic power scales of the universe, from atoms nearly frozen to stillness. To Earth's largest explosions. From stars colliding, exploding, to distant centers of power so strange, and violent, they challenge our imaginations. Today, energy is very much on our minds, as we search for ways to power our civilization and serve the needs of our citizens. But what is energy? Where does it come from? And where do we stand within the great power streams that shape time and space? Energy comes from a Greek word for activity or working. In physics, it's simply the property or the state of anything in our universe that allows it to do work. Whether it's thermal, kinetic, electro-magnetic, chemical, or gravitational.

In this University of Southern California program, Robert Kuhn hosts a group of distinguished panelists in a discussion of what may lie beyond our world. Humans have long wondered whether life exists beyond our home planet. In recent years, a host of new technologies are turning speculation into science. We now have the ability to discern the atmosphere of an extra-solar planet so distant we can't even see it, to detect the presence of dozens of new planets circling stars similar to our own sun.

Explore the biggest question of all... in 1080p. Since ancient times, we've looked into the night skies and wondered: How far do the stars stretch out into space? And what's beyond them?

This is a very, very old film/conversation. It was made in 1988. In a studio setting, Stephen Hawking, Arthur C. Clarke and Carl Sagan (who joins them via satellite) discuss the Big Bang theory, God, our existence as well as the possibility of extraterrestrial life.

World-renowned astronomer and prize-winning professor of astronomy at the University of California, Berkeley, Alex Filippenko, explores some of the mysteries of the universe at a special lecture at the Santa Barbara Museum of Natural History. Filippenko discusses observations of very distant exploding starts called super-novae that provide intriguing evidence that the expansion of the universe is now speeding up. Over the largest scales of space, the universe seems to be dominated by a repulsive "dark energy" of unknown origin, stretching the very fabric of space itself faster and faster with time.

In this National Science Foundation program, Sean Carroll, a senior research associate at the California Institute of Technology, sheds light into the "dark side" of the universe that may actually be the key to unlocking the mystery that is the universe. The type of matter we're familiar with and encounter everyday - atoms and molecules - only makes up about 5 percent of the universe. The remaining 95 percent is believed to be dark matter and dark energy. Explore the history of dark energy and dark matter by following Einstein's path to uncovering the theory that sparked a change in the world of astrophysics and the controversies behind that theory.

This is a clip from a BBC documentary explaining Hawking radiation around black holes.

How common are Solar Systems like our own? How common are rocky worlds like our Earth? Are they suitable for life? Join Dr. Alan Dressler, famed for his studies of distant galaxies and of the large-scale structure of the universe, as he searches for life in the universe.
