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 😊

[CordovaMage]

I like to picture a man with very tiny tweezers just plucking away at a piece of gallium going "one germanium, two germanium"

[NikkiTrudelle]

If there were ever a Nobel prize for science communication it should go to Anton for sure

[ericclubb]

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.

[dgermain]

I love how precise the whole physic thing is so that small discrepancies in niche experiment can spark wild new discoveries.

[wotireckon]

Hope you don't mind I sent a right-handed thumbsup.

Unexplained physics involving Gallium? Never clicked on a video faster!

This is what happens when I forget I took my meds and I take them twice. Oh wait that's Valium

The Gallium Anomaly is the name of my last psychedelic jazz album. Very popular in Japan.

You have the gift of presenting information in a format that is easy to understand. Don't retire, there is a lot more I want to learn.

How an experiment intended to study one phenomenon leads to insights in an entirely different arena is foundational science, and probably why there are so many people who don’t buy into it anymore. It’s simply too complex for lots of people. Easier to believe what your favorite politician has to say on the subject. A fascinating presentation well told. You are the man, Anton. And a wonderful one.

[jimcurtis]

Wonderful as always Anton. Thank you. ☺️👍

[deemo]

that smile gets me everytime.
Always love the vids ty

[MagnumGreenPanther]

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

Left-handed neutrinos are more creative than right-handed neutrinos.

[JanghanHong]

There was always something weird and mythical about room temperature liquid metals.

[TheBluemanBenny]

Thanks Anton. Awesome work as always!

[andrewepp]

Crazy that people are able to think up these kinds of experiments. Humans can be pretty smart!!

[George-rkts]

There's been talk of sterile neutrons for a long time. This time it might make sense.

Stay wonderful, Anton

Hi Anton,
Karl here from the UK. Hearing you mention right handed neutrinos reminded me of Neil Turok’s amazing lecture about (I believe) his ground breaking theories a few months ago. He pointed out that as these particles were much heavier than left handed neutrinos they were a likely candidate for dark matter. I urge you to watch his 2 hour (!) long talk/lecture on the YouTube ‘Theories of Everything’ channel entitled The Simple Theory That Explains Everything’. Enjoy!!
