Sean Carroll: What is an Atom?
2 segments available
This is a clip from a conversation with Sean Carroll from Nov 2019. Check out Sean's new book on quantum mechanics titled Something Deeply Hidden: https://amzn.to/2C6aCaf New full episodes once or twice a week and 1-2 new clips or a new non-podcast video on all other days.

Ultimately, this podcast is a small side hobby for me with the goal of sharing and discussing ideas. For now, I post a few clips every Tue & Fri. I did a poll and 92% of people either liked or loved the posting of daily clips, 2% were indifferent, and 6% hated it, some suggesting that I post them on a separate YouTube channel. I hear the 6% and partially agree, so am torn about the whole thing. I tried creating a separate clips channel but the YouTube algorithm makes it very difficult for that channel to grow unless the main channel is already very popular. So for a little while, I'll keep posting clips on the main channel. I ask for your patience and to see these clips as supporting the dissemination of knowledge contained in nuanced discussion. If you enjoy it, consider subscribing, sharing, and commenting. Sean Carroll is a theoretical physicist at Caltech and Santa Fe Institute specializing in quantum mechanics, arrow of time, cosmology, and gravitation. He is the author of several popular books and is a host of a great podcast called Mindscape.

Segments Timeline
The Birth of Atomic Theory
Sean Carroll discusses the historical development of atomic theory, tracing its roots back to the ancient Greeks and highlighting the pivotal discoveries made by chemists in the 1800s. He explains how John Dalton's observations of tin oxide led to the acceptance of atoms as real entities, despite initial resistance from physicists, particularly in Germany. This segment sets the stage for understanding the evolution of atomic science.
"what is an atom and what is an electron sure this all came together you know in a few years around the turn of the last century right around the year 1900 Adams predated then of course the word atom g..."
Understanding Atoms and Electrons
In this segment, Carroll elaborates on the modern understanding of atoms as the smallest building blocks of chemical elements. He explains the structure of the atom, including the nucleus made of protons and neutrons, and the role of electrons in chemical reactions. Carroll emphasizes the significance of quantum mechanics in modeling electron behavior, marking it as a key area of interest in physics.
