  • The Most Bizarre Substance Known to Science and What It Can Do

    The Most Bizarre Substance Known to Science and What It Can Do
    Mar 4 2026
    If ever there was a criminally underrated natural resource, it would have to be Helium. Though most commonly associated with party balloons and making one’s voice sound like a cartoon, Helium’s most important application is in cooling the magnets of Magnetic Resonance Imaging or MRI machines. While the finite and ever-dwindling global supply of this vitally important gas is a topic worthy of its own video, perhaps even more fascinating is just how bizarre an element Helium truly is. For if Helium is liquefied and cooled to a low enough temperature, it begins to behave like no other liquid on earth, seemingly violating the laws of gravity, thermodynamics, and even logic itself. This is the story of superfluid Helium II, the weirdest substance known to science. In order for Helium to be liquefied, it must be cooled to a temperature of -268.8 degrees Celsius or 4.2 Kelvin – that is, only 4.2 degrees above Absolute Zero, the coldest temperature theoretically possible. By contrast, Nitrogen liquefies at a relatively balmy 77 Kelvin, Oxygen at 54 Kelvin, and Hydrogen at 33 Kelvin. The reason Helium is so difficult to liquefy lies in its electron orbitals being completely filled, making it – like the other noble gases Neon, Argon, Krypton, Xenon, and Radon – electrically neutral and chemically inert. This means that the only force which can pull Helium atoms together is the so-called Van de Waals Force, which is caused by electrons shifting from one side of an atom to the other and creating a momentary electrostatic charge. This force is incredibly weak, meaning that Helium must be cooled to extremely low temperatures in order for the Van de Waals forces to overcome the energy of the moving atoms and pull them close enough together for the gas to liquefy. Solidifying Helium is even more difficult – so difficult, in fact, that it cannot be done at regular atmospheric pressures. Only at pressures of 25 atmospheres and above can solid Helium be created.

  • How the Hell Did Winston Churchill Lose the Election Right After Defeating Germany?

    How the Hell Did Winston Churchill Lose the Election Right After Defeating Germany?
    Mar 3 2026
    Nazi Germany officially surrendered on May 7, 1945. With the war still raging in the Pacific against Japan and sporting a popularity rate at around 83%, Sir Winston Leonard Spencer Churchill seemed a shoe-in to maintain his position as Prime Minister of the British Empire. Just before the announcement of the results of the election, Churchill had been at the Potsdam Conference with U.S. President Truman and Joseph Stalin, only intending to travel home briefly to accept his victory, and then back to the conference. Yet a funny thing happened on July 26, 1945, the voting populace of the UK, which had turned out in record numbers of 73%, had decided to collectively say “Thanks for your service, Winston, but we’ve decided to go in a different direction,” in a landslide defeat that shocked the world. While in more modern times you might think some sort of scandalous affair or offensive comment may have whipped up the mob on the interwebs precipitating such a massive electoral fall in the span of just a couple months, there was no such issue here either. So what happened? How did this wildly successful politician, frequently named among the top Prime Ministers ever in the nation, at the height of his popularity no less, and who had just helped successfully guide Britain through one of its most harrowing periods of its storied history, not just lose, but lose in a landslide? And not only this, making the whole thing even more inexplicable, he lost to a man who one of said man’s own party members, Aneurin Bevan, stated “seems determined to make a trumpet sound like a tin whistle.” Or as chairman of the Daily Mirror, Cecil King, would remark in 1940, he was “of very limited intelligence and no personality. If one heard he was getting £6 a week in the service of the East Ham Corporation, one would be surprised he was earning so much.” Or, let’s not stop there, as famed social reformer Beatrice Webb would remark, “He looked and spoke like an insignificant elderly clerk, without distinction in the voice, manner or substance of his discourse. To realize that this little non-entity is… presumably the future Prime Minister, is pitiable.” Or how about as Churchill himself would allegedly quip about his opponent, he is "a modest man, but then, he has so much to be modest about." The demeaning quotes about the man Churchill lost to go on and on and on, and his own party before, during, and after the election likewise tried to oust him as their leader…. Only to see this quiet, oft’ forgotten individual who rapidly rose from a middle class background to the heights of power, defy them all and go on to become one of the greatest Prime Ministers in the history of the nation, often even ranked above Churchill himself, despite only serving in the position for a handful of years. As ever, of course, the devil is in the fascinating details, so let’s dive into it, and what specifically happened to see a titan of history defeated by a man likely no one outside of the UK even knows the name of, yet shaped the Britain we have today arguably more significantly than Churchill ever did.

    The Real Color of the Sun, How Many Nuclear Bomb Powered Rockets It Would Take to Stop the Earth Orbiting the Sun and Much, Much More
    Mar 2 2026
    ⁠⁠In this episode of The Brain Food Show, we begin by discussing the clandestine way Niel Armstrong managed to get his application to the astronaut program in despite submitting it past the deadline. We then look at why he got to be first to walk on the moon when precedent should have had it been Buzz Aldrin. Next up we look at the oft’ forgotten second thing Armstrong said when stepping out onto the moon. Moving swiftly on we do a rapid fire of a variety of space related bonus facts including, but not limited to, the real color of the Sun, how much energy it would take to cause the Earth to stop orbiting the Sun, how old the Sun is in Sun years, how many Sun rises and sunsets astronauts aboard the International Space Station see every day, etc. And for those curious on Simon and my treatise on the proper order of watching Star Trek series and other such thoughts, ⁠the mentioned forum post is here.
