Erich von Falkenhayn had been fired from his position as Chief-of-Staff but he had a new task: Leading the combined Austro-German forces into Romania. So, this week 100 years ago Falkenhayn crosses the Carpathian mountains into Transylvania where they met fierce Romanian resistance. At the same time the British attacked at the Somme again and failed to utilise their new weapon: the tank. » HOW CAN I SUPPORT YOUR CHANNEL?

These warbirds were once in active military service, battling it out in dogfights. Now they are the play things of the fabulously wealthy, men who only have the best of everything. This pastime is only for the seriously rich, not your average weekend hobby. One wrong move and these machines kill even the best pilots in the world. The perfect adrenalin rush for the seriously rich alpha male, and a chance to prove they are top guns! Jet airplanes revolutionised warfare, they first came in to service at the end of World War II, and over the next 50 years evolved into the most lethal killing machines. Air superiority fighters like the F-15 and the MiG ruled the skies, while planes such the F-16 or A-10 still strike fear into their adversaries. Once these extraordinary warplanes were flown by trained military pilots on deadly missions, but now they have become the toys for some of world’s high flyers.

Now, I live on the West Coast, so I’m soft and weak, rarely experiencing temperatures below freezing. But for some of my Canadian brethren, temperatures can dip down to levels your mind and body can scarcely comprehend. For example, I have a friend who lives in Winnipeg, Manitoba. For a day last winter, the temperatures there dipped down -31C, but with the windchill, it felt like -50C. On that same day, it was a balmy -29C on Mars. On Mars! But for scientists, and the Universe, it can get much much colder. So cold, in fact, that they use a completely different temperature scale - Kelvin - to measure how far away things are from the coldest possible temperature: Absolute Zero. On the Celsius scale, Absolute Zero is -273.15 degrees. And in Fahrenheit, it’s -459.67 degrees. In the Kelvin scale, however, it’s very simple. Absolute Zero is 0 kelvin. At this point, a science explainer is going to stumble into a minefield of incorrect usage. It’s not 0 degrees kelvin, you don’t say the degrees part, just the kelvin part. Just kelvin. This is because when you measure something from an arbitrary point, like the direction you just turned, you’ve changed course 15-degrees. But if you’re measuring from an absolute point, like the lowest physical temperature defined by nature, you drop the degrees because it’s an absolute. An Absolute Zero. Of course, I’ve probably gotten that wrong too. This stuff is hard. Anyway, back to Absolute Zero. Absolute Zero is the coldest possible temperature that can theoretically be reached. At this point, no heat energy can be extracted from a system, no work can be done. It’s dead Jim. But it’s completely theoretical. It’s practically impossible to cool something down to Absolute Zero. In order to cool something down, you need to do work to extract heat from it. The colder you get, the more work you need to do. In order to get to Absolute Zero, you’d need to put in an infinite amount of work. And that’s ridiculous. As you probably learned in physics or chemistry class, the temperature of a gas translates to the motion of the particles in the gas. As you cool a gas down, by extracting heat from it, the particles slow down. You would think, then, that by cooling something down to Absolute Zero, all particle motion in that something would stop. But that’s not true. From a quantum mechanics point of view, you can never know the position and momentum of particles at the same time. If the particles stopped, you’d know their momentum (zero) and their position… right there. The Universe and its laws of physics just can’t allow that to happen. Thank Heisenberg’s Uncertainty Principle. Therefore, there’s always a little motion, even if you could get to Absolute Zero, which you can’t. But you can’t extract any more heat from it. The physicist Robert Boyle was one of the first to consider the possibility that there was a lowest possible temperature, which he called the primum frigidum. In 1702, Guillaume Amontons created a thermometer that he calculated would bottom out at -240 C. Pretty close, actually. But it was Lord Kelvin, who created this absolute scale in 1848, starting at -273 C, or 0 kelvin. By this measurement, even with its windchill, Winnipeg was a balmy 223 kelvin on that wintry day. The surface of Pluto, on the other hand varies from a low of 33 kelvin to a high of 55 kelvin. That’s -240 C to -218 C. The average background temperature across the entire Universe is just 2.7 kelvin. You won’t find many places that cold, unless you get out to the vast cosmic voids that separate galaxy clusters. Over time, the background temperature of the Universe will continue to drop, but it’ll never actually reach Absolute Zero. Even in a Googol years, when the last supermassive black hole has finally evaporated, and there’s no usable heat left in the entire Universe. In fact, astronomers call this bleak future the “heat death” of the Universe. It’s heat death, as in, the death of all heat. And happiness.

Captain America finally gets his own Avengers movie. Wait... I mean... The Avengers finally show up to help out in one of their members solo films. Wait... Spider-Man finally doesn t suck in a film about not-Spider-Man... wait...
