Is Democracy Still Viable?
Two new libertarian authors think it's time to let a thousand nations bloom.

Greed is killing the American dream
Like our TV programming, politics in America is a race to the bottom. In politics, 'bottom' means the bottom line.

The idiocy of audacity
Whether you're crossing the street or voting for your leaders, one slip in judgment can create an irreversible catastrophe.

The Curse of Oslo
Giving the European Union the Nobel Peace Prize has ominous implications for its future.

Stress and Reproductive Fertility
A politician has created a furor by claiming the body has some protective mechanism to prevent unwanted pregnancy. But is that really true? What are the scientific facts?

By using the power of the State to suppress viewpoints that the majority do not want to hear, are European societies actually encouraging violence?

Another Day, Another Economic Catastrophe
Why does it feel like the world is coming to an end this week? Didn't we just get an end o' the world last week?

Don't Blame Science for Climategate
Global warming just might be the most important problem facing Western civilization since the cold war. Not because of anything the globe is doing, but rather because our politicians have all gone stark raving mad because of it.

Obama's Upcoming Inflation Crunch
It is a truism that government spending cannot create wealth. Yet some economists, following John Maynard Keynes, believe that government spending leads to disproportionately higher private spending--a so-called "multiplier effect" that creates wealth.

Why do people believe in God?
Where does the concept of God come from? Why do people believe in God? In this article, I will try to avoid political questions and simply speculate, from a scientific point of view, where the concept of a God might have originated.

Ben Stein's Curious Post-Modernist Adventure
Is the theory of evolution responsible for the Nazi Holocaust? To scientists, the idea is as ludicrous as the idea that Marie Curie is responsible for the atomic bomb, the idea that the theory of gravity is responsible for wiping out the dinosaurs, or the idea that "2+2=4" is responsible for four-wheel drive.

Politics in Nature Neuroscience
Another inflammatory political article has turned up. Not in New Republic or Weekly World News as you might expect, but in the scientific journal Nature Neuroscience.

Intelligent Design: Is it a theory?
What is this all about? Is intelligent design really an alternative to Darwinian evolution? Is it a valid scientific theory? As scientists we must remain open to all new ideas, no matter how bizarre. Many scientists have strong religious beliefs. At the same time, if intelligent design is not a valid scientific theory we should be honest and say so.

The Precautionary Principle: Common Sense or Sloppy Thinking?
In this article, I will discuss several situations that have been proposed as justifications for the so-called "precautionary principle", and show that in each case, a risk-benefit analysis produces a superior result. I will also show that, contrary to what has been claimed, the precautionary principle is not commonly followed by responsible public officials, scientists, or law courts, and argue that it should not be adopted as an element in decision-making.

The Al Gore Effect: Theoretical basis
Recent research has shown that the presence of Al Gore is able to reduce ambient temperatures by approximately 27.6°C. This phenomenon is termed the "Al Gore Effect." Various theories about the physical mechanism of this phenomenon, and its potential usefulness in fighting global warming, are discussed.

An Overview of Santa's Advanced Anti-Radar Technology
For years, radar operators at airports have complained about the difficulty of detecting Santa Claus on radar. But according to radar experts, the inability of our most advanced radar tracking systems to detect the red-suited Christmas icon is no accident.

The Cow Theory of Economics
Cow theory is a well-established tool for understanding basic economic concepts. There are many variations of this theory on the Internet. Here are some new ones.

The Tragic Story of Schrodinger's Cat
Schrödinger's cat played a critical role in the early development of quantum mechanics. He is most well known for his famous thought experiment, in which he postulated that a measurement made by an observer could determine the outcome of a quantum event. His paper on the subject, published in 1935 in the prestigious journal Naturwissenschaften, established his reputation as a first-rate theoretical physicist.

What car would Jesus really drive?
An organization called the "National Religious Partnership for the Environment" has started a national campaign to make people feel guilty for driving SUVs. The centerpiece of this campaign is the slogan, "What would Jesus drive?". This, of course, has driven people into paroxysms of laughter.

Biochemistry as Portrayed in the Movies
Many people have pointed out that phenomena in the movies are unrealistic from a physics standpoint. However, as far as I know, no one has mentioned the movie stunts that break all the laws of biochemistry. If anything, these offenses against the laws of nature are even more improbable than the physics mistakes.

Physics envy among biologists: fact or fiction?
Physicists often state their belief that all biologists would rather be physicists, but became biologists only because they were not very good at math. Why, physicists ask, do biologists seem unable to utilize such simple concepts as the Riemannian-Christoffel curvature tensor or Galois fields in their work?

Introduction to Quantum Thermo-Epistemology
This manuscript describes some of our recent findings in the exciting new field of quantum thermo-epistemology, a branch of implausibility theory dealing with fundamental questions such as: Why does toast always land butter-side down?
