(Phys.org) -- With simple arguments, researchers show that nature is complicated. Researchers from the Niels Bohr Institute have made a simple experiment that demonstrates that nature violates common sense – the world is different than most people believe. The experiment illustrates that light does not behave according to the principles of classical physics, but that light has quantum mechanical properties.

Working at Scientific American , known for its spiffy technical illustrations, I always look for material that can show what an article is trying to tell.

In the consumer-tech sense, friction is inconvenience. It's a hassle--steps that stand between you and what you want to buy or do.

In many parts of the U.S. and here in New York City, we ve had the pleasure of experiencing above-normal temperatures, and the sunshine has brought hibernating city-dwellers outdoors to soak up the warm rays while enjoying a number of activities jogging, playing basketball, riding bicycles, or just lounging on park benches. Over the weekend, I was running along the East River when a man rolled by and caught my eye

Our earliest invertebrate ancestors did not have brains. Yet, over hundreds of millions of years, we and other vertebrates have developed amazingly complicated mental machinery

The faster a clock ticks, the more precise it can be.

Scientific American editors Mark Fischetti and Michael Moyer discuss some of the sessions they attended at the annual meeting of the American Association for the Advancement of Science.

The Advances section of Scientific American 's March issue discusses how reducing soot emissions could be a quick, if temporary, fix for global warming; explains why cramming for tests doesn't work; and examines physicists' latest efforts to make an object disappear.

A study led by Jonathan Tilly of the Massachusetts General Hospital overturns the decades-long idea that women are born with all the eggs they will ever have. It reports that women of reproductive age carry ovarian stem cells, meaning that they can produce new eggs. Tilly’s team, which made a similar finding in mice in 2004 , also discovered that mouse eggs derived from such stem cells can indeed be fertilized.

Following up on my post yesterday about my own journey with science, I wanted to offer some words of encouragement to those who are still in the early stages of their own journey.

How to Explain Climate Change to a Skeptic Rick Santorum has recently described climate change as a hoax a bunch of bogus science that tries to make nature s normal boom and bust cycle into something man-made. His comments illustrate how, despite the fact that the scientific community accepts climate change as truth, and despite the fact that the science is gaining greater acceptance among the general public, you may still run into people that just don t believe the theory of climate change. In my experience working for oil companies and environmental organizations alike, I have heard pretty much every argument for and against climate change

I am very happy to introduce the newest addition to the Scientific American blog network Unofficial Prognosis , written by Ilana Yurkiewicz ( Twitter ). Ilana is a first-year student at Harvard Medical School who created Unofficial Prognosis to capture her reflections through her medical training. She graduated summa cum laude with a B.S
