Skeptoid Episode Guide - General Science


What Really Happened at Tunguska (Skeptoid #803) - History and old photos tell us that something destructive happened over a Siberian forest in 1908, knocking down trees over 300 square kilometers. And though it's usually said that this was the result of an exploding meteor, many alternate theories have been proposed as well. And so we're forced to wonder: What really did happen at Tunguska, and more importantly, how do we know that?

Pop Quiz: 15 for 15 (Skeptoid #802) - Skeptoid is the podcast about the true history and true science behind our urban legends and strange beliefs, and learning about how and why smart people come to believe weird things. And so by studying them, we end up learning a lot of random facts about all these popular stories. Today we're going to see just how many of these random facts about our world you've absorbed... with another pop quiz.

Why You Need to Care About Methane (Skeptoid #797) - For all the talk about carbon dioxide's role in climate change, we hear surprisingly little about methane. Some say it represents even a greater threat, but if that's so, why isn't it getting more attention? Today we're going to see what the science really says, and what we should be doing about it.

Is the Existence of Billionaires Inherently Harmful? (Skeptoid #790) - You can hardly turn around these days without hearing someone lecture about how immoral it is that billionaires exist. It's a popular view. But is this just an emotional or ideological reaction, or does economic theory also show that the existence of billionaires is actually harmful to a nation's economy or its people?

Desalination vs. A National Water Grid (Skeptoid #785) - As global warming causes floods to worsen in the eastern US, it also causes droughts to worsen in the west, a trend which will continue. Today we're going to look at the science behind two proposals to help with the west's new water-starved normal: desalination and a national water grid.

Space Junk: The Real Risk and What to Do About It (Skeptoid #781) - What happens when one satellite crashes into another, and then another?

Luckily we don't have to wonder, because we've got the science-based answer for you.

Bitcoin Fact and Fiction (Skeptoid #774) - Bitcoin, the best known cryptocurrency, has made millionaires and billionaires worldwide. Some say that it's a currency immune from the problems that plague national currencies, and some say it's all just a flash-in-the-pan fad with no real value. We're going to separate the fact from the fiction today and see how much of the fuss is justified.

Percy Schmeiser vs Monsanto (Skeptoid #759) - Everyone's heard about how Monsanto, the world's largest producer of genetically engineered crop seeds, is notorious for suing any farmer whose field happens to become accidentally contaminated when the wind blows seeds onto their land. But, as is the case with so many things that "everyone has heard," there's no truth at all in this one.

About That Life on Mars... (Skeptoid #754) - Remember that time you heard that scientists discovered life on Mars? It's been reported, several different times, in fact.

Today we're going to find out what happens when scientists speak too soon and out of place.

Observing the Bystander Effect (Skeptoid #749) - Have you ever heard of the Bystander Effect? It's when you're the only one around, you're more likely to spring into action if there's some emergency; but if there are lots of people around, nobody tends to do anything, like they're all expecting someone else will do it. It's been a staple of behavioral psychology for a long time, but newer work might cast some doubt on whether this truly does represent what real people do in the real world. Will you take action next time you have a chance?

Who Sank the Maine? (Skeptoid #748) - When the USS Maine blew up and sank in Havana harbor in 1898, it plunged the United States and Spain into a costly and bloody war. And almost immediately, fingers began pointing in all directions over who blew it up. Was it a false flag attack by the Americans? Was it done by the Cubans to force the US into a war against the Spanish occupiers? More than a century later we have better forensic and other data than ever... and maybe even the answer to this long standing riddle.

Phineas Gage, on Second Thought (Skeptoid #744) - In 1848 a man named Phineas Gage blew a crowbar right through his head with blasting powder, but somehow survived the appalling injury. It became a bedrock case in neurology. If you've heard his story, you might have heard that his personality completely changed as a result of the brain injury. But today, neurologists are taking another look, and correcting some of the ways poor Phineas has been misused by the textbooks.

The Wisdom and Stupidity of Crowds (Skeptoid #741) - The "wisdom of crowds" is an idea, backed by experimental validation, that a big group of random people can collectively guess at something and do better than trained experts -- a very frustrating proposition for those experts. But while this concept sounds like it might be the miracle solution everyone's looking for to solve any complicated problem, the reality is very different.

Learning Languages from Brain Injuries (Skeptoid #716) - Every so often we get a news story about someone who wakes up from a coma, and suddenly they're speaking a different language -- one that they did not know before their injury. Or sometimes, they wake up speaking only in some strange foreign accent. That's the way these stories are reported by the popular press, but when we point the skeptical eye at them, we find out that whatever is going on is something else entirely.

Banning plastic bags has always seemed like a great low-hanging fruit for fighting pollution and global warming, but when you look at the science, one starts to wonder whether any economists, climatologists, or materials scientists were consulted in developing these bans. Because the science sure doesn't look like it...

All About Sex Addiction (Skeptoid #708) - Sex addicts make for great Hollywood movies. They make for saucy reading in saucy magazines and novels. They even find their way into our courtrooms, where sex addiction has been used as a defense. But when you ask psychologists whether it's even a real thing or not, you might be surprised to hear what they have to say. Or, what most of them have to say, anyway.
