I'm a bit worried about whether the shaking comes across on camera. If you can use a big screen, please do! It's almost impossible to be close enough to see the shaking AND static reference points AND to have enough movement that it shows up on camera. But the noise? The noise, at least, sells it for me.

As a project engineer, who is rarely allowed to demo anything on site, i feel the pain of the engineer who had to use the u-turn and was most likely told "look, you can't demo that wall and we're not giving you the budget to build a new building. Just make it work in this area."
-
It's amazing to see the engineer go from "explaining to a stupid journalist like a child" to "geeking out with Tom about fluid dynamics"
-
Tom trying to remember which one is pitch, roll, and yaw while doing the hand movements is shockingly relatable
-
Tom losing his mind over a u-turn in the pipes is the clip I would show somebody to describe his personality
-
Tom showing understanding of what the guy is talking about feels very genuine. He’s truly interested.
-
The level of technology needed to simulate an earthquake kinda shows how strong they actually are
-
I've been part of this project for 7 years, and Koorosh is a good friend. It's great to see this team get recognition from amazing folks like Tom for the fantastic work they do every day to make the world a safer place from earthquakes!
-
I like the video ending on "The next test will commence in 10 minutes". They're really putting that building through the paces. They can casually run a serious earthquake test and then say "oh it's not over, there's aftershocks for like... the next few months". I really like that they have a system in place that allows that level of rigor.
-
Thanks for coming out, was awesome getting to work with you! For anyone wondering it is just as much fun seeing Tom get excited about a U-turn in person.
-
That guy was probably the best you have ever interviewed. He loves it and isn't 100% serious like others. Fantastic video all round.
-
"You have to fail safe." That statement alone tells you how crucially important an engineers job is when designing systems of any kind.
-
It's always extra entertaining to see Tom interact with someone he vibes with.
-
I believe this is the second video that Tom has done on artificial earthquakes. Interesting to see how much he's refined his technique since then.
-
The test really showed how insane Earthquakes are. A controlled test on a safe building with favorable conditions, and I still am in awe at how terrifying that looked. As Tom put it "I do want to turn and run".
-
Tom was clearly blown away by the U-turn, but said nothing about the fact that, right after the U-turn, the pipes create TWO SIDE-BY-SIDE T JOINTS??? I can't even imagine the violence
-
As an expert in something myself, I can tell you that Dr. Lotfizadeh really enjoyed that interview because you came into it already with a moderate understanding of many of the fundamental principals.
-
Glad to know that even artificial earthquake centres have picked their battle in the Y-up/Z-up debate
-
It's strange to hear Tom Scott have so much emotion, it really sells how insane the thing is.
-
I want an hour long documentary on the engineering and construction of this thing. It's incredible!
