    I like to picture a man with very tiny tweezers just plucking away at a piece of gallium going "one germanium, two germanium"
  • @StasKubrak
    I used to work on BEST as a student, have written trigger program in C++ to detect certain neutrino events. Nice to hear that old place still is relevant for modern science 😊
  • Unexplained physics involving Gallium? Never clicked on a video faster!
  • @ericclubb3761
    This is one of my favorite science channels. Your one of the only channels I know about, who talk abou new discoveries, that aren't complete bs clickbait and you actually use real pictures. You, John Micheal Godier, Vsauce, and PBS Spacetime are my favorite science channels.
  • @dgermain001
    I love how precise the whole physic thing is so that small discrepancies in niche experiment can spark wild new discoveries.
  • @JanghanHong
    There was always something weird and mythical about room temperature liquid metals.
  • @NikkiTrudelle
    If there were ever a Nobel prize for science communication it should go to Anton for sure
  • @andrewepp6763
    Crazy that people are able to think up these kinds of experiments. Humans can be pretty smart!!
  • @cliffcc
    I have been using germanium for about 10 years now in the mixture I use to make silver items. After a good bit of tinkering, I found a simple ratio of 97% silver, 2% copper and 1% germanium makes a silver purer than jewelry silver, very resistant to tarnish, more reflective and it gives to the ability to heat-harden the material making it scratch resistant and more durable than 925. Another benefit is that is changes the cool down rate of the molten silver, if you ever poured silver, you know it sets fast, when germanium is introduced, it extends the pouring time and seems to allow the silver to flow better. If you try this, the germanium has the tendency to crack and pop when heating, just beware. Totally off topic, sorry.
  • This is what happens when I forget I took my meds and I take them twice. Oh wait that's Valium
  • @wotireckon
    Hope you don't mind I sent a right-handed thumbsup.
  • 20-24% less than expected. That tells you that there is a particle flavor that we don’t know about. Instead of a 1/3 it’s 1/4 or a 1/5

    The Gallium Anomaly is the name of my last psychedelic jazz album. Very popular in Japan.
  • Best thing about these videos is they remind me how stupid I really am. Time for me to go hug an experimental astrophysicist.
  • @chrislong3938
    Heh... every time I hear the word 'Germanium' I think back to a Biggles novel I read as a child! Algy was planting Geraniums around their Quonset hut and Biggles dug them all up saying that he won't have Germaniuns growing at their base! This was the book when he first met Algy in WWI. A fun read for a kid!!! ... and yes! I'm American but grew up in the British WI. I'm probably one of the few Americans who knew what the hell Ian Anderson was talking about where in Thick as a Brick, he asks, "... and where the hell was Biggles, when you needed him last Saturday?"
  • @deemo8578
    that smile gets me everytime. Always love the vids ty
  • @George-rk7ts
    There's been talk of sterile neutrons for a long time. This time it might make sense. Stay wonderful, Anton
