@5:38 "So you know, looks like your garden variety death-ray." ~Awesome~

That machine from the 1930’s is massive. That is impressive that it is still actively being used after all these years.

[@AteJesLover]

This is so cool! Thanks Ariel awesome vid:)

[@ArielWaldman]

SLONGexclamationmark - thanks!

[@johnwolf7073]

awesome vid :P keep it up !

[@ArielWaldman]

Thanks, John!

[@aeoli4921]

Hello Cave Johnson here, I NEED THOSE NEUTRINOS!!!!!!!!!

[@sulljoh1]

Very cool!

[@ArielWaldman]

Thanks!

[@MedSou]

thanks, for sharing this experience with us 👍👍👍👍👍

[@ArielWaldman]

Very happy to. Thanks for tuning in :)

[@MultiNacnud]

that's the same mine where doctor Raymond Davis worked and won (shared) the nobel prize for physics in 2002 for his work on solar neutrinos.Is there is a plaque to commemorate this?

[@ArielWaldman]

yes, I heard about that! there might be

[@ekotar1]

I interned at SURF over the summer. There are MANY things named in honor of Davis there.

[@zapfanzapfan]

Did it feel like you were travelling to the center of the Earth? Was it notably warmer down there?

[@RC-1290]

In case you don't get a proper reply from Ariel: The one time I went into a salt mine, the temperature was indeed quite high, compared to the temperature outside the mine.

[@ArielWaldman]

It felt a bit humid and warm in parts, but they also had air conditioning in other parts.

[@RC-1290]

Air conditioning, nice! (Humidity definitely wasn't an issue in the salt mine.... the opposite ^_^ . And breathing salt dust isn't the most pleasant thing ever :P)

[@josh34578]

Thanks for coming out to SD. I actually live in SD but couldn't make it across the state for this event. Was your keynote at the event recorded?

[@ArielWaldman]

Sorry you missed it! I believe they did record it, so I imagine if you follow Sanford Lab they'll post it on one of their channels. SD was great!

[@di99utpe]

Why do you need to "shoot" neutrinos from so far away to study them? Couldn't you just shoot them from the next room?

[@ekotar1]

Because we're concerned with timescales -- there are several different Neutrino detectors that exist as part of DUNE, the one at SURF is the farthest away. We know over long distances any sample of neutrinos will flip between all three flavors, eventually homogenizing. . . But what about over shorter distances? How does this process occur? We have to measure over many distances to find out!

[@carmenschumann826]

. . . so how 'cool' is it one mile down (Kelvin, pls.) ?

[@ArielWaldman]

It was fairly humid and warm down there, actually!

[@robertfrench7336]

You are brave.

[@ArielWaldman]

Robert French - thousands of people have gone up and down it for almost a century!
