Playlist: NASA Connect, Ancient Observatories

NASA Connect video containing four segments as described below. NASA Connect segment explaining the foundations of astronomy and the how the Earth moves relative to the sun. This segment explains how the Earth's tilt creates the 4 seasons. NASA Connect segment explaining how the height of the sun relates to the growing seasons and the length of daylight. This segment describes how Ancient Egyptian and Greek cultures used astronomy in their lives. The segment also contains an activity for exploring how a gnomon works. In the activity students must track the shadows made by a gnomon in 30 minute intervals. The activity will teach students how the length of the shadows and the angles created by the gnomon are related to the position of the sun. NASA Connect segment that shows two examples of how the Navajo used used structures to track progress of the sun in the sky. NASA Connect segment describing the Ancient Mayan civilization and their accomplishments. This segment compares the Mayan counting system to the Roman counting system and has a brief exercise for students to add the numbers 21 and 33 using both systems.

Dan Gilbert: Why are we happy? Why aren't we happy? TED | Talks (video)

Harvard psychologist Dan Gilbert says our beliefs about what will make us happy are often wrong -- a premise he supports with intriguing research, and explains in his accessible and unexpectedly funny book, Stumbling on Happiness.

Psychologist Dan Gilbert challenges the idea that we'll be miserable if we don't get what we want. Our "psychological immune system" lets us feel real, enduring happiness, he says, even when things don't go as planned. He calls this kind of happiness "synthetic happiness," and he says it's "every bit as real and enduring as the kind of happiness you stumble upon when you get exactly what you were aiming for."

Ray Kurzweil: How technology's accelerating power will transform us TED | Talks (video)

Prolific inventor and outrageous visionary Ray Kurzweil explains in abundant, grounded detail why -- by the 2020s -- we will have reverse-engineered the human brain, and nanobots will be operating your consciousness. Kurzweil draws on years of research to show the speed at which technology is evolving, and projects forward into an almost unthinkable future to outline the ways we'll use technology to augment our own capabilities, forever blurring the lines between human and machine.

Ray Kurzweil is an engineer who has radically advanced the fields of speech, text, and audio technology. He's also one of our finest thinkers, revered for his dizzying -- yet convincing -- writing on the advance of technology, the limits of biology, and the future of the human species.

Two Million Galaxies


"Two Million Galaxies Credit & Copyright: S. Maddox (Nottingham U.) et al. APM Survey, Astrophys. Dept. Oxford U. Explanation: Our universe is filled with galaxies. Galaxies -- huge conglomerations of stars, gas, dust -- and mysterious dark matter are the basic building blocks of the large-scale universe. Although distant galaxies move away from each other as the universe expands, gravity attracts neighboring galaxies to each other, forming galaxy groups, clusters of galaxies, and even larger expansive filaments. Some of these structures are visible on one of the most comprehensive maps of the sky ever made in galaxies: the APM galaxy survey map completed in the early 1990s. Over 2 million galaxies are depicted above in a region 100 degrees across centered toward our Milky Way Galaxy's south pole. Bright regions indicate more galaxies, while bluer colors denote larger average galaxies. Dark ellipses have been cut away where bright local stars dominate the sky. Many scientific discoveries resulted from analyses of the map data, including that the universe was surprisingly complex on large scales. "

A HISTORY OF THINKING ABOUT THE FUTURE

"Description: Interest in the future is not new. Human reason and imagination have always compelled people to reflect on the past and speculate on what will be. This essay surveys the principal means humans have used over the millennia to consider the long-term future and how their actions might affect it."

Arpanet Documentary

The Interstate network of highways was created in the 1950s as a defense project. The Internet also got started as a defense project. The United States Department of Defense's Advanced Research Projects Agency (ARPA) in the early 1970s was very interested in networking computers to be able to couple the compute power of several computers. Originally it linked only four universities. Today the Internet links millions of computer around the globe.

The Life of Buddha - BBC

Life of the Buddha is a major landmark documentary following Buddha on his journey from the lap of luxury to the verge of starvation and final enlightenment. Shot on location in Nepal and India, Life of the Buddha uses dramatic computer-generated images and recent archaeological discoveries to piece together this remarkable story.

Over 2,500 years ago, one man showed the world a way to enlightenment. This beautifully produced Buddhist film meticulously reveals the fascinating story of Prince Siddhartha and the spiritual transformation that turned him into the Buddha.

A. Einstein - The World As I See It

Einstein ´nuclear´ letter to President Roosevelt, 1939



Scientists in the 1930s, using machines that could break apart the nuclear cores of atoms, confirmed Einstein's formula E=mc² . The release of energy in a nuclear transformation was so great that it could cause a detectable change in the mass of the nucleus. But the study of nuclei -- in those years the fastest growing area of physics -- had scant effect on Einstein. Nuclear physicists were gathering into ever-larger teams of scientists and technicians, heavily funded by governments and foundations, engaged in experiments using massive devices. Such work was alien to Einstein's habit of abstract thought, done alone or with a mathematical assistant. In return, experimental nuclear physicists in the 1930s had little need for Einstein's theories.
In August 1939 nuclear physicists came to Einstein, not for scientific but for political help. The fission of the uranium nucleus had recently been discovered. A long-time friend, Leo Szilard, and other physicists realized that uranium might be used for enormously devastating bombs. They had reason to fear that Nazi Germany might construct such weapons. Einstein, reacting to the danger from Hitler's aggression, had already abandoned his strict pacifism. He now signed a letter that was delivered to the American president, Franklin D. Roosevelt, warning him to take action. This letter, and a second Einstein-Szilard letter of March 1940, joined efforts by other scientists to prod the United States government into preparing for nuclear warfare. Einstein played no other role in the nuclear bomb project. As a German who had supported left-wing causes, he was denied security clearance for such sensitive work. But during the war he did perform useful service as a consultant for the United States Navy's Bureau of Ordnance.
