  • The rumours are indeed true, I have a Twitter and Patreon. Check the description for the links. Also, ask me questions for my (very delayed) Q&A! FOOTNOTES BELOW, THEY HAVE SPOILERS SO BEST READ AFTER WATCHING ********************************************************** 1. You’ll notice I didn’t mention a neutrino as part of the beta-minus decay. This is partly because I was lazy, but also because the neutrino wasn’t a widely accepted concept at that point, and Fermi actually had a paper rejected for trying to account for its existence. 2. The nuclide half-life data included in my version of the chart was sourced from NuBASE 2020, Chinese Physics C45, 030001 (2021). This dataset distinguishes between known half-lives, estimated half-lives, and nuclides whose half-lives are so small that they are unknown. I removed the nuclides with unknown half-lives for my chart. See the link in the description for an interactive version of the table. 3. Only a select number of isotopes on the nuclide chart have labels. I labelled every stable isotope (in brown), and for the unstable isotopes I only labelled the one with the longest half-life for each element. Note that the isotope with the longest half-life is not necessarily the one that was created for each element discovery. 4. The half-lives on the 3D nuclide chart are not plotted linearly (or logarithmically for that matter) as it would be impossible to show the differences between half-lives in the realm of nanoseconds and half-lives in the realm of years in a way that didn’t completely flatten half the chart. The standard way to plot them is to use the quantile method, where you take all the values (~3000) and rank them from smallest to largest, which the height of each pillar being their rank (so 1, 2, 3…3000). I then made a color gradient using 10 distinct colours, and if a pillar was in the first 10% of the population they got the darkest blue, the next 10% got a lighter blue, etc. 5. The following elements were first synthesized in labs before they were discovered in trace amounts in nature: Technetium, promethium, astatine, neptunium, and plutonium. For many years it was assumed that Uranium was the heaviest naturally occurring element, but this was actually disproven by Darleane Hoffman, when she found trace amounts of Plutonium-244 in ancient pieces of rock. 6. The Lanthanides and Actinides (the two seemingly detached rows of the periodic table) are a bit misleading. They’re put below the main table for space reasons, but really they fit right in the middle of the table next to Barium and Radium, leading to a table that is comically wide, too wide to be printed cleanly in a textbook. It should be noted that the periodic table during Fermi’s time didn’t look like the modern one I showed in the video. For a long time the correct position of the Actinide and Lanthanide groups were a bit of a mystery. It was actually Glenn Seaborg’s suggestion in the mid-1950s that put them where they are today, which was one of his most important contributions to chemistry. 7. Berkeley should technically also have a claim to element 43, but they just didn’t realize it. Emilio Segre, one of Fermi’s protégés, borrowed a spare filter from one of Berkeley’s accelerators. He found a lump of element 43 on it that they had unknowingly created, and he got the credit for detecting it. Many labs other than Berkeley worked to fill in the gaps of the periodic table, as well as filling in the gaps in the nuclide chart. Finding new elements gets you the glory, but finding new isotopes is also important for getting a full understanding of an elements properties. 8.If we’re being technical a superheavy element is one which has an atomic number greater than 103. This term distinguishes them from elements 90-103 which make up the Actinide series. In my version of the periodic table I group every element above 103 in the same category for simplicity, but there are other ways you could group them. If you check with Google for example they actually call 104 to 108 part of the transition metals, and everything higher is considered unknown. In theory everything up to 112 should also be part of the transition metals, but that’s mostly going off of the table’s columns and not so much measured observations. 9. The price for one gram of an element is going to vary a lot depending on the specific isotope. Also Einsteinium isn’t commercially available to buy anyway, and it’s only ever been produced in the order of micrograms, so Jeff Bezos couldn’t just drop $27 million out of nowhere. 10. The California town of Livermore is home to another strange oddity. A firehouse contains the world’s longest burning lightbulb. It’s been going since 1901. It could burn out tomorrow, or maybe even 15754 years from now. 11. Technically it’s 221 totals winners for the Nobel prize in physics now, didn’t beat the announcement for this year. 12. Masataka Ogawa seems to have misidentified element 75 as element 43 back in 1908 (both of which were undiscovered at the point). Both elements are in the same column but different rows, so the chemical properties would be similar. If it had been correctly identified Japan would have 2 elements under its belt, not just 1. 13. During the IUPAC naming section I mention that 9 elements needed official names, even though I only show 8 getting named. When writing this I forgot that Mendelevium was not officially recognized as the name for #101 until 1997, even though Berkeley had the only real claim to it. IUPAC just lumped it in with the rest of the contentious elements (102-106). 14. Lawrence Livermore Labs had in fact teamed up with Berkeley for the discoveries of prior elements, so they were not new to the element hunt. However their team-up with Dubna gave them a huge leg-up over Berkeley and eventually made them the leading US lab in the element hunt. 15. Victor Ninov was fired in May 2002, but the public retraction of the paper did not go through until July 2002. It was only at this point that the media picked up on the story. Berkeley initially did not name Ninov as the reason for the retraction but the media was able to put 2 and 2 together. 16. Flerovium is technically not named after Georgy Flerov. The Americans refused to let an element be named after someone who was integral to developing the first Soviet nuclear weapon, so the element is actually named after the Flerov Laboratory (which itself, it named after the man). 17. I mention in the first chapter that it was a group in Berlin that figured out Fermi’s mistake, and explained it by describing nuclear fission. This group included Otto Hahn and Lise Meitner. Hahn went on to win the Nobel for this, while Meitner did not, despite being nominated a few dozen times (Hahn and Meitner were good friends, so he wasn’t happy about this either). It’s one of the most clear-cut cases of sexism in the Nobel ceremony’s history. To make up for this, she is now the namesake for element 109, one of only two women to have that honour.

  • I was learning chemistry in school around at that time. We had a periodic table on the wall went until 108 or 109 (I don't remember clearly, I only remember, that bohrium was already there, but I'm not sure about hassium and meitnerium). The one in the textbook went further but elements 110-118 were kinda funny: they had dotted lines and their names were stuff like unununium and ununpentium - basically the Latin name of their number. I asked my teacher, why these ones aren't featured on the periodic table on the wall and why they look and are named different than the others (I also learned Latin in school, so I knew where they names came from). My teacher said, that elements are still discovered to this day and there are some arguments about how they should be named, that's why they use these placeholder names. This was the time, when rutherfordium was still called kurchatovium in some textbooks (I grew up in a former Eastern Bloc country), so we were aware of naming controversies. I've never thought, that my teacher was refering to this, when he was talking about "some arguments"... On the other hand, it's understandable, that he doesn't wanted to talk about a still ongoing scandal in the scientific world with a group of 13 year olds who just started to learn chemistry.

  • This video kicked ass. I’ll admit that it’s been recommended to me by YT for awhile now, and I kept assuming that it wouldn’t be a story interesting enough for an 80min runtime. That was wrong! You told this story beautifully, balancing the technical science of these discoveries with the stories of the humans behind them. I was on the edge of my seat the entire time, as much as I could while operating a sewing machine. And your use of graphics was perfect; just the right amount of graphics organized to keep the beats of the story accessible in mind and provide context to their relation in time. Also the 3D isotope table was such a cool way of visualizing them! 10/10, will watch again.

  • Fun fact the element missing in the 1930’s period table between 84 and 86 is astatine(AT) which is also the rarest element to naturally find. In fact, they discovered it by making it synthetically and it was later on they found it naturally. To this day only 25 grams maximum has been discovered naturally at once. It is also very much radioactive and has no uses currently but is being tested for research with cancer and is synthetically made. The most “stable” isotope of astatine is astatine-210 which only makes it a little over 8 hours. Its fast decay rate is why it is so rare. Enjoy this random chemistry fact or facts

I was so pleased to see Darleane Hoffman get a positive shout out; she is a wonderful woman and actively participated in lab group meetings while I was around. This incident was never mentioned to me in the course of my work - I learned about it randomly in a separate context while I was working in the lab.

My great grandma used to write to him asking him to deploy her on the naval ship instead of as an infantry unit (she was a medic and I shit you not her reason for redeploying her was to meet a captain/admiral and marry him, AND IT WORKED!) Another time she wrote because she wanted a flat in St. Petersburg, which was also granted to her. She wasn't even remotely as important as Georgii Flyorov, it boggles the mind, but people actually just wrote to Stalin to ask him to do some shit, and they would get a response usually.

Then present your information mainly through, voiceover to avoid distractions (and cut down on editing). You use simple infographs and images to help explain concepts without breaking flow, and a couple of easy listening instrumental tracks to enhance mood, while keeping attention. Boom, you got something you can either listen to as a podcast style, watch as a documentary, and you walk away knowing something you haven't before. SummoningSalt also does this but includes video clips of speed runs. Defunctland is also starting to do this with his video essay on lines/queueing.

Fake the data and assume that someone else was going to find it anyways and he would get credit like he had before. They were taking his word for what he was claiming which is not good checks, and he was gambling that someone else would find it. He lost that bet when nobody could find it. So he was not so much relying on nobody trying to reproduce so much as he was betting that it would actually work and that they would just not check his to see if he had actually done it like before.

    @snek6769@snek6769 Жыл бұрын
    • Well this isn't totally true. The block of elements that's separated from the rest of the table in its usual form is called the Lanthanides and Actinides, or Rare Earth Metals, or f-block. It does contain some of the trans-Uranic elements (those with an atomic number higher than Uranium, which are all at least somewhat unstable). From Mendelevium (101) onward, these elements are only produced via synthetic nuclear fusion as described in this video, so only a couple atoms of each have ever existed. (Fermium (100) has been found in mushroom clouds and Einsteinium (99) and lower can actually be produced in measurable quantities in nuclear reactors (albeit this is literally micrograms).) The actual reason for the f-block is different: the periodic table is arranged so elements with similar properties are in the same column, and in chemistry a lot of properties are determined by the outer electron orbitals. The noble gasses have full outer orbitals so they are very averse to reacting at all. The Halogens (column before) are only missing one electron so they react well with the first column where elements have one extra electron. But orbital shells aren't the same size. There's the s orbital, p, d, f, and others, but each has a minimal energy level and so only occurs in atoms with enough electrons. The s orbital can only hold 2 electrons and is present in all shells. This is why the first row of the periodic table only has two elements. The p orbital however can hold 6 electrons, but it only exists in the second shell and onward. This is why the second row and onward have the block on the left of the periodic table. It's also why helium is sometimes placed over Beryllium instead of Neon. The d orbital holds 10 electrons but only occurs starting at the 4th shell; it corresponds to the central block of the table, the Transition Metals. The f orbital is the last one which occurs in any element we've discovered or synthesized, holding 14 electrons starting in the 6th shell. The exact numbers involved here come from the quantum numbers of electrons in a spherical potential. IIRC element 121 would theoretically have one g-orbital electron, but d and f orbital electrons are less chemically significant than s and p, and for elements with very high atomic numbers their chemistry is even less cut and dry.

    • And it looks so beautiful! You can immediately see why nature isn't as random and chaotic as we often observe it. Everything you see going on in the chart has fairly simple logic to it that (in certain aspects) isn't much different from the simple physics we see in everyday life. The bigger something is, the easier it falls apart and it seems that the right ratio of neutrons to protons helps keeping things together, but too much neutrons will make it unstable also. Which makes total sense to me. You can build a wall with bricks and cement, but just using one or the other will fall apart easily. And when your wall is tiny, extra neutrons will just make it wobbly. And it never occurred to me that with a higher number of protons the stable elements have a few more neutrons than protons. It's very intuitive and easy to understand and seeing the alpha and bèta decay on the chart made so much sense to me. It's super obvious that it works like that, but when do you ever picture it like that in the context of other elements around it? Schools should beg mr. Broccoli to let them use that chart to explain the periodic table and radioactivity. You could show that chart to a 10 year old and they'd understand and be thrilled that they do.

  • 38:25 - So, I met and knew Victor in 2007 while I was a flight instructor in Oakland, California. While I knew (from Wikipedia) the story of the Element 118 debalce, I never asked him about it. For what it's worth, he is absolutely a "dude you'd like to have a beer with" (although not before or during any flying), highly intelligent, and would give you the shirt off his back if you asked him. And while what occurred with 118 was definitely bad, I am still honored to count him as a friend.

    • i feel like most people, even if they've done shitty things, are still gonna be polite/friendly to you if you interact with them. i dont think that's something notable, that's just a standard you should hold people to. it would be more notable if he was an asshole to you

    • Charm is a great asset for manipulators. I doubt he would have been able to decieve everyone if he was generally mean, disrespectful or even reserved/shy.
