E=MC². Who really understands what lies behind Albert Einstein's famous formula? Follows the development of his scientific ideas with great cinematic style. The documentary deftly combines an appreciation of Einstein's scientific accomplishments, his trials and tribulations in gaining recognition, and his relationships both personal and professional.

Using crisp images and lifelike animations, this program introduces students to the intriguing realm of stars and galaxies. The main characteristics of galaxies and stars are discussed. Special attention is given to the features of stars, including size, temperature, and brightness. The life cycle of a star is also highlighted, as are the tools used by astronomers to study space. Additional concepts and terminology illustrated in the video include: universe, telescope, satellites, constellations, star color, spectrum, gas, light-year, and black hole.
Millions of years ago, a group of bacteria, the cyanobacteria, developed a new way to harness energy from the sun. This new development had important consequences for the evolution of both the atmosphere and the diversity of life on Earth.
There isn't an easy answer to the question: What is the nearest galaxy to the Milky Way? The Andromeda Galaxy is the closest complete galaxy; however, astronomers have found several dwarf galaxies orbiting the Milky Way. Part of the "Ask an Astronomer" series.
How far is a star or a galaxy? Scaling and measuring the cosmos is a complex problem. Scientists are integrating mathematical applications and scientific technology to create measurement standards. Distances are so vast they are described in light years, and nearby stars are measured by trigonometry. Farther out, astronomers use standard candle measurement for deep space exploration.
Matthew Schneps is a researcher at Harvard University with a doctorate in physics from the Massachusetts Institute of Technology (MIT). He also happens to have dyslexia, so reading has always been a challenge for him. That is, until he got a smartphone. Schneps soon found that for him, a smartphone was easier to read than a paper or a book. But, was it just him? Or, had he stumbled onto something that could help others with dyslexia?

Features different systems of measurement and their value to science in five separate segments. Stardust Elements: Looks at the life cycles of stars and explains how the death of a star seeds the universe with all the elements of the periodic table. End of Dinosaurs: Debates several scientific theories about why and how dinosaurs became extinct. Earthly Thermometers: Demonstrates how the Fahrenheit, Celsius, and Kelvin scales measure the same thing in different ways and why we need precise measurements of temperature. Frozen in Time: Pieces together the past of a 5,300-year-old man whose body was preserved in ice in the Italian Alps. Hurricanes Take the Heat: Follows researchers who study how hurricanes form and try to predict where the next one will strike.
Dr. Chris meets an inspirational 7-year-old who suffers from a brittle bone disease. Her dog Daisy is having some dental issues that she needs Dr. Chris to fix. Then at SASH, a 6-year-old aspiring vet helps Dr. Lisa. Part of the "Dr. Chris Pet Vet" series.
At first, the back room of plant physiologist Edgar Spalding's lab at the University of Wisconsin-Madison might be mistaken for an alien space ship set straight out of a Hollywood movie. It's a room bathed in low-red light with camera lenses pointing at strange looking entities encased in Petri dishes. A closer inspection reveals the Petri dishes contain nothing alien at all, but rather very down-to-earth corn seedlings. They're grown in red light for optimal growth. They're just one of the plants featured in thousands of time-lapse movies Spalding has created over the past five years. The goal is to figure out how to grow crops optimally.
Every year, a million babies are born worldwide with hereditary diseases. Physicians once had little to offer. Now a new breed of gene doctors is on the case. They are devising treatments that target the root causes of these diseases. Please note this title contains potentially offensive language.
Ethiopia's Rift Valley seems a barren landscape, but it hides untold archaeological riches. Dig in with Wild Chronicles and National Geographic researcher Zeray Alemseged and unearth a three-million-year-old baby. This historic discovery of tiny bones may shed new light on man's ancestry. Segment of video from Wild Chronicles Series.
Is there life on other planets? How can it be found? Presents the scientific theory of life's beginning and evolution on earth before considering life within our solar system and beyond. Discusses possible planet formation from stellar dust and technology's place in locating such planets.
For many years the Hubble Space Telescope has collected breathtaking images of the cosmos with remarkable clarity. Now, ground based telescopes are fighting back. They are combining the precision of several instruments and correcting for atmospheric shimmer. This program presents and explains the designs, uses, and outputs of different types of telescopes.
More energy from the sun hits the Earth in one hour than is consumed on the planet in a whole year. Caltech chemical engineer Sossina Haile and University of Minnesota mechanical engineer Jane Davidson are working to expand the nation’s renewable energy storage capacity. Their mission is to put the heat of the sun to work creating renewable fuels from sources that don’t need to be drilled out of the ground. Part of the National Science Foundation Series “Science Nation.”
For years, people have thought of ketchup as a condiment packed with flavor, but light on nutrition. Recent research has shown that heated tomato products are loaded with lycopene. This substance is easily absorbed by humans and may even help fight cancer, heart disease, and possibly even osteoporosis. Part of the "Science to Go With Dr. Joe Schwarcz" series.
The Big Bang theory is currently the most popular scientific theory for the origin of the universe. It describes how the universe emerged from an enormously dense and hot state about 13.7 billion years ago and how the universe is still expanding from that point. This theory helps scientists explain the formation of all the galaxies, stars, and planets.
In this episode, host Dianna Cowern explores one of the most mysterious discoveries in physics from the 1960's: a constant microwave signal that seemed to be coming from everywhere in the universe. It turned out to be light from an unusual process 13.8 billion years ago and originated from the beginning of the universe. Part of the "Physics Girl" series.
With support from the National Science Foundation, Astrobiologist Richard Hoover really goes to extremes to find living things that thrive where life would seem to be impossible--from the glaciers of the Alaskan Arctic to the ice sheets of Antarctica. He thinks it is even possible that over the course of billions of years, life has spread around the solar system--a sort of cosmic cross pollination. Microbes could live in the ice deep within comets, frozen there for eons until a collision with another planet or moon delivered them to a new home.
Using mud, clay, and tons of stone, ancient civilizations built buildings and monuments that are still standing today. The Egyptians built the Great Pyramid with an accurate measuring system, the ability to calculate areas and volumes of triangles, and a tremendous workforce that transported 1,000 tons of stone each day for 15 years. Other civilizations, such as the Romans, created marvels of engineering like the dome of the Pantheon, and built clean cities that included conveniences such as water management and sewers.
Is it possible that climate change could have kick-started the end of antiquity and heralded the beginning of the Dark Ages? New scientific insights point to the impact of the eruption of the Ilopango Volcano in Central America. The eruption was violent and propelled ash into the stratosphere. As a result, the sun struggled to break through the ash. The following 10 years were extraordinarily cold, and this was the beginning of a time period marked by famine, war, and an almost complete loss of cultural heritage. Part of the "How Climate Made History" series.
