Understanding the COOL guy Refrigerator..

Refrigerator: Food preservation was a serious challenge before the discovery of refrigerators. The best options were to suspend spoilable items in the rivers, wells, or at the bottom of ponds. In spite of that, sometimes stable foods were heavily salted, spiced, pickled, canned or dried to prevent bacterial growth. With the industrial age, we began to understand thermodynamic cycles and through an interplay of pumps, valves, and heat exchange; we learned to cool food to arbitrary temperatures using the refrigerator cycle. So, Let's learn about its three crucial components and understand how they come together to produce the refrigerator’s cooling cycle. Question: What is the basic idea behind a refrigerator? Answer: It removes heat from the compartment and pumps it to the outside. Refrigerators continually take away heat from the air in the food compartment and dump it into the environment. The internal compartment of a refrigerator is approxima...

The Freaky Physics of Falling Slinkies, in Super Slow Motion

You have to see it to believe it: Slinkies look crazy not just tumbling down stairs but in free fall. In a new video, YouTube's favorite Slow Mo Guys capture the puzzling dynamics of the iconic toy at 1,600 frames per second on a Phantom Flex camera. The video, which we discovered via the curators of awesomeness at L aughing Squid , is not the first to look at the phenomenon and the Slow Mo guys ( Gavin Free and Daniel Gruchy ) are willing to admit their take is not exactly super informative. Luckily Rhett Allain, an associate professor of physics at Southeastern Louisiana University, has an in-depth look at the science at work over at Wired . He cites the YouTube series Vertiasium , which went viral with a similar falling-Slinky demo last fall. In the video below, physicist Rod Cross explains that the tension of the spring counters the pull of gravity ("equal and opposite force...
