#497 – Biggest Mysteries in Physics: Antimatter, Dark Energy & ToE – Don Lincoln

**Lex Fridman** (0:00)
The following is a conversation with Don Lincoln, a particle physicist at Fermilab, who has spent decades working at the frontier of high-energy physics. This was a mind-blowing and inspiring conversation. Don turned out to be one of my favorite people to talk to about physics. Truly a unique mind with that Richard Feynman ability of taking very complicated ideas and explaining them simply, without losing any of the essential brilliant insights at the core of those ideas.
And now, a quick few second mention of each sponsor. Check them out in the description or at lexfridman.com/sponsors.

This episode is also brought to you by Lairden, a platform that helps organizations understand how AI is being used across their business and what it's doing for productivity and performance. AI is clearly revolutionizing the way we, each individual, many of us are living our individual lives. But when multiple people come together and they use AI tooling, agentic engineering, together with multiple other people, especially at scale to accomplish the mission, the task, the big overarching moonshot task that a company chases, that is a fascinating puzzle, fascinating optimization problem. But it starts with data. A company needs to understand how the AI tools are being used. That's what Lairden does. It tracks the usage data and outcomes, allowing businesses to figure out how to maximize productivity and how to connect all the different use cases and activity around AI to actual results for the business. If AI is part of your organization, now's the moment to start optimizing its utilization. Head to lairden.com to book a demo and start maximizing impact from AI.
This episode, I'm not sure why I'm so hyped, but I am, is brought to you by Finn, the number one AI agent for customer service. Very few things are as important for business as taking care of the customer. This is the thing. When I had that conversation with Jeff Bezos, wonderful conversation on many levels, especially on the human level. Really, really, really a conversation I enjoyed very much. We'll probably do another one. Maybe we'll do one with Jeff and Elon together. Me as a person who loves space, who loves the ambitious literal moonshot of humanity, reaching out toward the stars, that makes me dream, that gives me hope about the future. So the two of them that are leading the way on those efforts being together at the table, I think would inspire a lot of people. Anyway, I say all that because Jeff has talked a lot about the value of the customer, about putting customer first. So getting the customer service piece right is incredibly difficult, but is incredibly important. And what Fin provides is tooling around that. It's trusted by over 6,000 customer service leaders, top companies, including AI companies. You know when AI companies trust your AI agent that is focused on customer service, you know then it's legit. And Fin is indeed legit.
