3D printers have been making headlines over the past couple of years. As 3D printing technology has evolves, prices have continued to decline and consumer grade versions can be bought for under $1000. Now comes one such story of a man named Cody Wilson, a 24 year old University of Texas Law student, who is spearheading a project to use 3D printing technology to produce firearms. Not only that, he’s sharing the blueprints online.
Remember that old Rockwell song “I always feel like somebody’s watching me”? Well, it wasn’t just his imagination. We are all being watched constantly. Whether you’re on the street, the subway, or even in your home, electronic eyes are searching for criminals and terrorists with technology that can make the invisible visible. Step behind the security doors and discover the secret–often disturbing–world of surveillance. Surveillance has been defined as the close observation of a person, particularly one under suspicion. This [...]
Join Dr. Steve Jefferts of the National Institute of Standards and Technology in Boulder, Colorado as he explains why atomic clocks are so extremely important in our everyday lives. Dr. Jefferts is an expert on how we measure time and he even co-developed one of the world’s most accurate atomic clocks. But why do we need such accuracy? Nature provides a bunch of clocks. In the past these natural clocks were used to tell time. For example: the sun rising [...]
French engineer Thierry Legault believes that people have a right to know that there are spy satellites (among others) above our heads. On a clear night these satellites can be easily spotted. They’re visible and the details can be identified with a telescope. Astrophotography is not only Legault’s hobby, it’s also his passion. A passion he developed at a very early age. Legault remembers fondly his first telescope which he received as a gift from his parents. He enjoys passing [...]
In this documentary learn about SOFIA, a device that is much more than a telescope tucked into a commercial airliner. Eric Young, Director of the SOFIA Science Center explains that it’s a complete flying astronomical observation platform which carries a dozen or more astronomers, observers, and crew far above the clouds to observe objects and phenomena too cold to be seen in visible light. SOFIA stands for Stratospheric Observatory for Infrared Astronomy, and on the outside she looks a lot [...]
Have you ever wondered what makes up the sun? Is it solid? Is it a liquid? Is it a gas? With a diameter of more than 100 times that of the Earth and a surface temperature of five thousand degrees Celcius, one can safely conclude that the sun is very big and very hot. Discover more about this wonderful star as some common questions are answered in this documentary. It might look like a solid object, but the Sun is [...]
What happens when a Nobel Laurate and a Nat Geo Explorer come together? Well, they inevitably discover exciting and unexpected things. Join National Geographic’s 2011 Explorer of the Year, Environmental Anthropologist Dr. Kenny Broad, as he dives into a perilous submerged cave system known as the Blue Holes of the Bahamas in search of clues to evolution and climate change. Once submerged, he realizes how little we know about this fragile ecosystem. The discoveries he makes are mindblowing. Then listen [...]
In this documentary, listen to 15-Year-Old Kelvin Doe’s story. Kelvin is an engineering whiz living in Sierra Leone who scours the trash cans for discarded electronic parts, which he uses to build batteries, generators, transmitters and other intricate devices. Completely self-taught, Kelvin has created his own radio station “from scratch” where he broadcasts news and plays music under the moniker, DJ Focus. Recently, Kelvin became the youngest person in history to be invited to the “Visiting Practitioner’s Program” at MIT. [...]
Athene has come up with a theory about everything: philosophy, physics, chemistry – both between humans and objects. This is a fascinating theory that draws from numerous fields of study. Worth watching! Review included.
Earth’s continents are set on a collision course and geological inquiry tells us the consequences could be cataclysmic. The tectonic plates are drifting away from their original formation and towards each other once more. Will humanity survive?
The Earth has its share of problems: too many humans live on its crust. There are earthquakes, hurricanes, and tidal waves. Humans are looking for alternatives. Space is often mentioned, but the far more realistic new world is under the sea.
A stunning real-life Alien Fireball hurtled toward Earth and was captured by a vast network of specialized technology. It paints a fiery picture of evolution, the dinosaurs, and the vulnerability of modern civilization.
Some of the best science fiction revolves around the notion of a parallel universe: where things are slightly different from the universe you are used to. Popular on Star Trek, a surprising number of scientists have recently become convinced that the theory is grounded in hard science.
The Most Explosive things in the Universe. This documentary reads like a love letter to the Big Bang theory. All the pyrotechnics out there should count their lucky blessings that the Universe began with such a bang.
What are the mathematical odds of intelligent alien life? Using applied mathematics, this fun animated video will show you the possibility of how alone we truly are in the universe.
Size Matters: from our vast solar system to our galaxy and universe. Enormity is unimaginable. Then the particles and atoms…smaller and larger than we can comprehend.
