How Much Did Top Gun: Maverick Cost the U.S. Taxpayer? Nov 24, 2025

Show notes

Countless films produced in the United States feature use of rather expensive military equipment, and often also real world military personnel. Given the extreme expense of all of this using things paid for by the U.S. taxpayer to benefit for profit companies, how is this allowed? Further, how are projects that the military will support selected? Can just any U.S. citizen apply for use of such equipment and personnel for their particular project to make it fair to all? Just how much does this cost the U.S. taxpayer in cases like, for example, the recent wildly profitable Top Gun: Maverick? And why and how did all of this get started?

What Did the German Public Know About the Holocaust During WWII? Nov 22, 2025

Show notes

While something like the holocaust isn’t exactly unprecedented in history, with mass genocide popping up an unnerving number of times the world over throughout our time humaning, perhaps no other instance of this has shocked the modern world more than the Nazis systematically murdering somewhere in the ballpark of 5 or 6 million Jewish people along with another 5 or 6 million people of other backgrounds, such as the lesser talked about Romani genocide. In this one, the Nazis murdered upwards of a million Romani, which was about half the entire Romani population of Europe at the time. That any civilized people could allow something like this to go on seems unthinkable to our modern selves, but the question becomes from this- how much did the general public actually know about what was going on at the time it was happening?

It turns out, contrary to what is often stated, quite a lot actually both on the global scale, and even within Germany itself evidence pointing to at least the idea that it was happening being relatively common knowledge, as we’ll get into shortly. But also, paradoxically, by accounts from many people directly after the war, they didn’t really know at all…

So which is true?

To really get to the bottom of this, we must discuss events leading up to the holocaust and how much of these the German people and wider world knew about.

WTF are Smelling Salts? Nov 19, 2025

Show notes

It is a scene out of countless romance novels and prestige period pieces: an elegantly-dressed Victorian lady, laced too tightly into her corset, is suddenly overcome by a case of “the vapours” and swoons - collapsing into a convenient “fainting couch” designed for just this purpose. Immediately a servant or dashing doctor rushes to her side, uncorks a small bottle of smelling salts, and holds it under her nose. She gasps, springs back to consciousness, and all is well.

Of course, most of this scenario is pure fiction. Contrary to popular depictions, the corsets was not some diabolical, patriarchal torture device that caused women to faint constantly - indeed, working women regularly wore them in the fields and factories - while so-called “fainting couches” were nothing of the sort - merely ordinary day beds for lounging. But smelling salts were a real thing, used for centuries to rouse both men and women from fainting spells; indeed, they remain popular today among many professional athletes. But just what are smelling salts? Who invented them, how do they work, and are they safe to use? Well, lace up your corset, position your couch accordingly, and prepare to be shocked into unconsciousness as we dive into what exactly are smelling salts and how exactly they work.

The Time a King Let the Leader of a Cult Become King to See if the World Would End Nov 16, 2025

Show notes

In today’s age of relatively stable international relations, it is hard to imagine the impact of something like the Mongol invasions. Starting in 1206, It was a trying time for those who initially witnessed them: mountains of skulls, burning cities, murder and pillaging on a wide scale. Even if Genghis Khan’

descendants became more urbane and grew closer to their conquered peoples, the initial shock of it all was massive. The conquered people struggled to make sense of the carnage and their new reality. New religious movements that promised a bright future rose to meet the new age. Some of these movements were as apocalyptic as the events recently witnessed. Out of the ashes of the old political order, new states were formed that looked to the Mongols for legitimacy, just as new religious reactions to the carnage looked to instill hope and resistance in the conquered people. A chain of events that could only arise from these conditions led to a very bizarre story of how a Persian king let a leader of a cult take the throne so apocalyptic prophecies could be fulfilled.

Crazy Cool Science- What Causes This Sand to Sing? Nov 14, 2025

Show notes

Picture, if you will, a desert. Chances are, the picture you now have in your head probably looks a lot like Namib-Naukluft National Park in Namibia, southwest Africa. Among the oldest deserts in the world, this park features a spectacular erg or sand sea of towering, golden-red sand dunes rolling off as far as the eye can see, one of which, known as Dune 7, is the largest in the world at a whopping 380 metres or 245.25 Ariana Grandes tall. Standing amid this desolate, sunbaked landscape, you would expect to be confronted by a profound silence, broken only by the soft whistling of the wind. But this is no ordinary desert, for every so often, the silence will be shattered by a deep, powerful roaring sound, variously likened to thunder, distant drums, or the drone of a low-flying propeller aircraft. But alas for all you Dune fans out there, this ominous sound does not herald the approach of the giant sandworm Shai-Hulud (shy-huh-lood) bless the Maker and his water), but is instead produced by the sand itself. Such “singing” sands are surprisingly common, appearing in deserts and on beaches around the world from Morocco to Kazakhstan, Scotland, Canada, and Hawaii, and have been the subject of myth and folklore for centuries. Yet despite decades of scientific investigation, to this day no-one is quite sure what causes these sands to sing. This is the story of one of the last great mysteries of the natural world.

Who Invented the Band-Aid? Nov 10, 2025

Show notes

Finish the following sentence: “I am stuck on Band-Aid…” If you immediately sang: “…cuz Band-Aid’s stuck on me!”, congratulations: you have a 50-year-old ad campaign living rent-free in your head. A staple of every first aid kit, Band-Aids are a quick and convenient solution to all the minor cuts, scrapes, burns and other boo-boos life can dish out. Indeed, so fully have these little sticking-plasters permeated popular culture that the brand lent its name to the 1984 charity supergroup behind the hit song “Do They Know it’s Christmas?” while the term “band-aid solution” has entered the lexicon as a byword for temporary, often slapdash repairs. But while the idea of a gauze pad attached to a strip of adhesive tape might seem so basic that it must have existed forever, as we covered in our previous video Who Invented Duct Tape?, even the simplest inventions have to come from somewhere, and surprisingly the idea of the self-adhesive bandage is only a little over a century old. The story of how this simple idea went from home remedy to household name is one of a klutzy housewife, a devoted husband, tireless innovation, and clever marketing. This is the fascinating story of the Band-Aid.

The Crazy Carnival Ride Soviet Turntable Procedure That Gave Us the First Corrective Eye Surgery Nov 08, 2025

Show notes

The eyes, they say, are the windows to the soul. More practically, they are our windows to the world, humans being one of many visually-dependent species on the planet. But they are also fragile windows, susceptible to all sorts of injuries, diseases, and disorders. Worldwide, over 2 billion people - nearly a third of the world’s population - suffer from some sort of visual impairment, ranging from mild glaucoma and cataracts to complete blindness. Of these, 88.4 million suffer from mild, easily correctable refractive errors such as nearsightedness, farsightedness, and astigmatism. For much of history, the only solution to such impairments was corrective lenses, but more recent years have seen the rise of advanced surgical corrective technology such as LASIK. Thanks to such safe, quick, and relatively painless and inexpensive procedures, thousands of people are able to enjoy perfect vision without the hassle of glasses or contact lenses. But no technology appears fully-formed overnight, and LASIK and its relatives owe their existence to a bizarre procedure developed in 1970s Soviet Russia which involved an assembly-line team of surgeons, diamond scalpels, and a rotating operating table that looked more like a carnival ride than a piece of medical equipment. This is the story of Radial Keratotomy, the world’s first successful corrective eye surgery.

Forgotten Hero- The Other Oskar Schindler Nov 06, 2025

Show notes

In 1993, legendary director Steven Spielberg released two groundbreaking films, which could not have been more different from one another. The first was Jurassic Park, a thrilling summer blockbuster and special effects landmark about bringing dinosaurs back from extinction. The other…was Schindler’s List. Widely considered one of the most heart wrenching films ever made, Schindler’s List tells the true story of Oskar Schindler, a German industrialist who, through his enamelware and ammunition factories in occupied Poland and Czechoslovakia, succeeded in saving over a thousand Jewish workers’s lives. Thanks to Spielberg’s film, Schindler is today perhaps the best known of the so-called “Righteous Among the Nations” - individuals recognized by the Yad Vashem memorial institution for assisting Jews and other victims of the Holocaust. But Schindler was far from alone, and his story bears a striking resemblance to that of another, more obscure figure: a fellow German businessman named Otto Weidt. While Weidt only managed to save the lives of around 30 employees, the sheer heroic lengths he went to to ensure their survival and defy the Nazi authorities makes his a story one well worth telling. This is the story of Nazi Germany’s forgotten “other” Oskar Schindler.
