PBS show It’s OK To Be Smart brings you the science behind Christmas. Why do the damn Christmas lights always tangle? How could Santa deliver all those presents (and none to me)? Why does Rudolf has a red nose? Hint: It’s not cancer. Check out the REAL science behind the questions:
After a disappointing threat to Sony from hacker group ‘Guardians of Peace’ (aka ‘The Crazies’ aka ‘All of North Korea’) last week, Dr. Evil makes a return to the spotlight to school the group on what it means to be truly evil.
Stick that in your pipe and smoke it, Kim.
The Terminator may be one BAMF but he ain’t no liar. “I’ll be back” holds true for Arnold when he returns to the big screen July 1, 2015. Check out the trailer for Terminator: Genisys
Swedish animator and digital artist Erik Wernquist created this visual masterpiece set to the narration of Carl Sagan about humanity’s potential expansion into the Solar System. Wanderers combines breathtaking visual effects and an imaginative narrative from Sagan’s 1994 book, Pale Blue Dot. If you geek out over all-things-space like we do it’s definitely worth the 4-minutes out of your day.
…and we’re not talking the kind of eruption you might experience after an evening of hard partying and a late-night McDonalds run. We’re talking the the kind that release deadly gases from within the earth.
The physics of a bar prank that causes beer to overflow with foam by tapping the top of a beer bottle is being used by researchers to explain the mechanics of volcanic eruptions of lethal gases. Researchers used high-speed cameras and focused laser pulses to examine how bubbles in beer bottles form when being “tapped” as occurs in the popular bar prank. The scientists found that a sudden impact induces waves that cause bubbles to expand and quickly collapse. The sudden collapse of bubbles form cavities that lead to explosions of foam which rush upward. The physics examined in this process are helping researchers better understand how deadly gases are released during events called limnic eruptions in which dissolved CO2 is suddenly released from the earth. “A better understanding of the physics behind limnic eruptions could be of interest to quantify when they could happen and, more importantly, how much carbon dioxide can be released,” one of the researchers reported.
