This is a cool video that describes the USGI compass and demonstrates how to use it to navigate.

New BIQ house will use microalgae facade to generate energy for the building while also providing dynamic shade
The zero-energy BIQ House in Hamburg, Germany sports a “bio-adaptive façade” that uses microalgae to generate renewable energy and provide shade. Algae in the bio-reactor facades grow faster in the brighter sunlight and hence, create a natural shade when the sun is at its brightest. In addition, the bio-reactors power the building by capturing solar […]
Lost in the shuffle, the news that a white beluga whale named “NOC” could speak rudimentary English was never published until colleagues encouraged Sam Ridgway, of the National Marine Mammal Foundation, to publish the news that many are not aware of – whales can mimic human speech just like a parrot. A new paper in […]
Everyone dreams whether they remember their dreams or not. In fact, most people have 3-4 dreams per night. In a “lucid dream state”, the person is aware that they are in a dream and have the ability to control the dream as they see fit. This gives the person a means to think, rationalize, invent, […]
Gorillas are considered to be highly intelligent. People are considered to be highly intelligent too – at least most of them are. In this video, note how the man handles being charged by a 400lb gorilla – by standing his ground and not flinching (his big balls probably keep him anchored pretty well too).
This video captured a remarkable scene where an octopus not only made quick work of the underwater food canister, but did so while fending off a pajama catshark with just one tentacle!
How to read the intent behind a person’s handshake (or how to promote yourself as a pompous bitch thru your shake)
Psychological studies indicate that much can be gleaned from a person’s handshake, especially when it’s the first time you’ve met the person and are forming that oh-so-important first impression. Psychologists say a person forms their impression of you in the first 5-10 seconds after they meet you and that once formed in the person’s mind, […]
In this video, Japanese astronaut, Dr. Takao Doi, throws a boomerang inside the International Space Station, in a zero-G environment. Before the experiment, they really were not sure what it would do, thinking it would probably spin up and away from the thrower, As it turns out, it acts pretty much the same as it […]
Youtube user hacakability has uploaded more amazing video, this time several segments showing in extreme slow motion, the falling and deformation action of water balloons. Very interesting and to be honest, quite beautiful.
This time lapse video is worthy of any horror show I’ve ever seen. They took a small camera and placed it inside the shell of a mussel. From the camera placed inside the mussel shell, you watch as the starfish then ejects its stomach into the mussel shell and eats it alive leaving nothing but […]
Called “The Great Unconformity”, the Grand Canyon has a 1.2 billion year gap in the rock record. Above the gap is 500 million-year-old sandstone (Cambrian age), a time of billions of shelled marine creatures. Below the gap is metamorphic rock of the Slatherian period aged 1.75 billion years where no fossils exist at all. But […]
Gravity Probe B gyroscope, holder of world record for roundest object ever manufactured, can spin for 15,000 years
Gravity Probe B is a satellite-based, relativity gyroscope experiment that launched in 2004 for the purpose of measuring the space-time curvature near Earth in order to test Einstein’s theory of general relativity. The experiment was to check, very precisely, tiny changes in the spin and angle of four gyroscopes contained in a highly sophisticated housing […]
If you place two metronomes on a stationary board and start them out of sync, they will remain out of sync forever. But if the board is placed on two rollers, so that the movement of the metronomes can be transferred through the moveable board, each metronome’s movement will affect the movement of the other […]
Each year, the Royal Observatory Greenwich‘s hosts its annual Astronomy Photographer of the Year competition. Now in its fourth year and growing, they received over 800 photo submission. Winners were announced on Sept. 19 in four main categories — Deep Space, Our Solar System, Earth and Space, and Young Astronomy Photographer of the Year — […]
Most geeks have fantasized about living in a space colony. What would it be like? Would you grow bored? What would you eat, where would you sleep, what would living in such close quarters with fellow colonists be like? Even NASA has pondered space colonization and in fact, it’s likely their ultimate goal.
Moon rocks are rarely offered for sale. Sample moon rocks collected by NASA’s Apollo astronauts are considered National Treasures, property of the United States government, and would never be sold to the public. They have been however, given away. Here are funny stories about lost moon rocks and tips on how you can come into […]
