15 Awesome Chemistry GIFs. You don’t need to watch Breaking Bad to know that chemistry is pretty awesome. Below, we explore our favorite 15 chemistry GIFs and the science behind them (when we could figure it out): Melting Metal With Magnets The Science: The copper wire has a significant amount of AC electricity running through it, causing it to act like a really strong electromagnet. In the metal slug, eddy currents form due to the magnetic field the copper wire is causing while the copper wire has high frequency AC flowing through it.
The metal slug’s electric resistance causes a portion of the electric energy to turn into heat, but the heat builds up until the metal slug becomes white hot and melts. Orange LED Light In Liquid Nitrogen The Science: When an LED is immersed in liquid nitrogen, the electrons lose a lot of thermal energy, even when the light isn’t turned on.

January 1, 2015. Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. At the same time, my lecture notes have evolved. This text owes a lot to many. I i i. Awesome Milk Trick. 60 insane cloud formations from around the world [PICs]
Cloud varieties go way beyond the cumulus, stratus, and cirrus we learn about in elementary school. Check out these wild natural phenomena. STANDING IN A CORNFIELD IN INDIANA, I once saw a fat roll cloud (like #4 below) float directly over my head. It’s a 12-year-old memory that remains fresh. There was a moment of mild panic just as the cloud reached me — Is this what a tornado looks like right before it hits? I thought. This is some freaky unnatural shit and I do not know how I’m supposed to react. I imagine a lot of these photographers having similar hesitations as they set up for the shots below.

Earth Science. Evolution. A billion years in the blink of an eye. One year in 40 seconds. Geology. Alligators: A Window Into An Ancient World. How amazing is it that we have creatures as old as dinosaurs living in our midst? Close ancestors of the alligator survived the event that wiped out the dinosaurs about 65 million years ago and as this graphic from the History Channel and Column Five details, there are some fascinating and unusual facts about the large reptile. Thanks to alligators, we have a window into how ancient creatures looked and acted. Food for thought: while alligator populations are currently large in the southern US, a place where the temperature supports the proper range for hatching eggs, it’s interesting to note how small a change in global temperature would select only one sex of offspring (as sex is determined by temperature during incubation).
How much will global warming change the range and the population of alligators in the future? Click here or the image below for a full sized view:
New Hypothesis for Human Evolution and Human Nature. Click on image for a high-resolution version. Domestic animals, like this water buffalo in Viet Nam, live intimately with humans and provide renewable resources to humans that communicate well with them. Photo by Greg Luna. 20 July 2010 — It's no secret to any dog-lover or cat-lover that humans have a special connection with animals. But in a new journal article and forthcoming book, paleoanthropologist Pat Shipman of Penn State University argues that this human-animal connection goes well beyond simple affection. Shipman proposes that the interdependency of ancestral humans with other animal species — "the animal connection" — played a crucial and beneficial role in human evolution over the last 2.6 million years.
"Establishing an intimate connection to other animals is unique and universal to our species," said Shipman, a professor of biological anthropology. Shipman suggests that the animal connection was prompted by the invention of stone tools 2.6-million years ago. . [ Kevin Stacey ]
