I've missed Don a lot over this last year. Physics is everything. ❤

Dr. Lincoln looks great and speaks even better.

Don is able to explain the indredible in the same way as Feynman was. A true educator.

Omg it's finally happening.
Go Fermi Lab!

Cannot believe I will have Don all for myself for almost 3 hours.

I had a career as a police dispatcher. After 20 years, I left to be a nurse. After 7 years, I need to get my bachelor’s in nursing. I’m trying to get in to Arizona State University because they have an online astronomy program. Man, I’d love to totally get what he’s saying.

Been watching Fermilab and Don Lincoln for years. Very good youtube channel!

This was a fascinating reminder that some of humanity's greatest breakthroughs came from realizing that two things that seemed completely unrelated were actually the same thing viewed from a deeper level. Newton unified heaven and earth. Maxwell unified electricity and magnetism. Einstein unified space and time.

What stood out most was Don Lincoln's point that discovery requires two things at once: imagination and criticism. The creative leap is important, but so is the willingness to relentlessly test your own ideas and expose them to scrutiny.

That's a lesson that reaches far beyond physics. Progress happens when people are humble enough to admit they might be wrong and curious enough to keep searching anyway.

The line that stuck with me was: "We all agree your idea is crazy, but is it crazy enough?" History is full of ideas that sounded impossible until someone proved otherwise.
As someone writing the Hero's Journey Adventure Series, this conversation really resonated with me. The best adventures aren't just about exploring distant places—they're about exploring ideas that challenge how we see reality.

Michelle Thaller on JRE yesterday and Don Lincoln on Lex today. This has been a good week for me.

Lincoln has sparked my interest in learning about particle physics with his Subatomic Stories podcast during covid lockdown. I've learned a lot about the principles and although I don't understand the math, it has motivated me to learn more about math and other sciences as well. I'm grateful for that!

Great work lex.

Really enjoyed this. You should have a whole series on physicists, each explaining the same topics in order to get the best way to communicate and understand these things.
@
Great having you back Lex!

Wow. This was one of the best podcasts on physics I've ever heard. His capacity for synthesizing complicated subject matter and making it accessible to non-experts is second to none.
@
Very nice to see Don Lincoln on the podcast. He has done so much at Fermilab as well as the physics education outreach work.

The Fermilab videos are my favourite physics videos thanks to Dr Lincoln. It's about time he's on!
@
It’s an absolute treat that we exist and are able to ponder any of this
@
Don Lincoln is the kind of science teacher that could make young people take an interest in physics instead of staring at their phones all day. Great communicator!
