Newton's laws are astonishingly successful at describing the world. They explain why apples fall from trees and why the Earth orbits the Sun. But they have an odd feature: they work just as well backwards as forwards. If an egg can break, then Newton's laws say it can un-break.This is obviously wrong, but nearly every theory that physicists have discovered since Newton has the same problem. The laws of physics simply don't care whether time runs forwards or backwards, any more than they care about whether you're left-handed or right-handed.But we certainly do. In our experience, time has an arrow, always pointing into the future. "You might mix up east and west, but you would not mix up yesterday and tomorrow," says Sean Carroll, a physicist at the California Institute of Technology in Pasadena. "But the fundamental laws of physics don't distinguish between past and future."

More than two decades before Brittany Maynard’s public advocacy for death with dignity inspired lawmakers in Washington, D.C., and at least 16 states to introduce legislation authorizing the medical practice of aid in dying for the terminally ill, Senator Frank Roberts of Oregon sponsored one of the nation’s first death-with-dignity bills.

“If we are dealing with robots like they are real people, the law should recognize that those interactions are like our interactions with real people,” Weaver writes. “In some cases, that will require recognizing that the robots are insurable entities like real people or corporations and that a robot’s liability is self-contained.” + Here’s the problem: If we don’t define robots as entities with certain legal rights and obligations, we will have a very difficult time using them effectively. And the tool that we have for assigning those things is legal personhood.

People in dense cities are thinner and have healthier hearts than people in sprawling subdivisions. New research says the secret is in the patterns of the streets.

“The Copernicus Complex addresses some of the deepest questions humans have ever asked. How weird are we? Was our existence highly probable, or improbable? Even miraculous? You can break this question down into more specific questions: How probable was our universe? Our galaxy? Solar system? Planet? How probable was life? And how probable were creatures like us, who can ponder their probability?

Scientists still don’t have a clue why our universe has the form we observe, or how life began on the Earth some 3.6 billion years ago, or whether life exists elsewhere. During his talk at Stevens, Scharf acknowledged that we may never observe exoplanets in sufficient detail to know, with certainty, that they harbor life.

“Unfortunately, you cannot determine the probability of the universe or of life on Earth when you have only one universe and one history of life to contemplate. Statistics require more than one data point.

Here are a few of the things that can make you hungry: seeing, smelling, reading, or even thinking about food. Hearing music that reminds you of a good meal. Walking by a place where you once ate something good. Even after you’ve just had a hearty lunch, imagining something delicious can make you salivate. Being genuinely hungry, on the other hand—in the sense of physiologically needing food—matters little. It’s enough to walk by a doughnut shop to start wanting a doughnut. Studies show that rats that have eaten a lot are just as eager to eat chocolate cereal as hungry rats are to eat laboratory chow. Humans don’t seem all that different. More often than not, we eat because we want to eat—not because we need to. Recent studies show that our physical level of hunger, in fact, does not correlate strongly with how much hunger we say that we feel or how much food we go on to consume. That’s something of a departure from commonly held views of what it means to be hungry.

The bottom line is that in East Asia, the predilection toward using face-coverings to prevent exposure to bad air is something that predates the germ theory of disease, and extends into the very foundations of East Asian culture. In recent years, however, mask-wearing has become rooted in new and increasingly postmodern rationales.

“Scientology works 100 percent of the time when it is properly applied to a person who sincerely desires to improve his life.”

Economics is a subject that polarises like few others. To some, it's an immoral calculating machine. To others, it's an amoral - not immoral, but amoral - science, descriptive pure and simple. To still more, it has a positively moral commitment to freedom by trying to increase people's choices.

What's puzzling is that morality so often comes thumping into it - when the subject has been taught for generations as if morality was someone else's job.

According to a new report by Calvin College assistant professor Jonathan Hill, many Americans do not think it's that important to have the "correct beliefs" on the origins of human life.

"No creationist wakes up in the morning and says, 'I have really strong opinions about whether Archaeopteryx is the ancestor of modern birds,'" he said.* "Who are we as people? That’s the question that they think evolution is answering. What does it mean to be a person? What does it mean to be an animal?"

What that means is that "debates" about evolution and creationism actually might not be that effective

Red is a powerful color

It means luck in China, where bridal wear is red, mourning in parts of Africa and sex in Amsterdam's red-light district.
