Overview

The Saturday Physics Series consists of five to seven scheduled talks oriented toward adults and high school students. Lectures occur on specific Saturdays afternoons throughout the school year, typically in Duane G1B30. Unless otherwise noted, lectures begin at 2:30 p.m., and usually last about one hour. Material is aimed at the level of high school juniors and seniors. The series is free, open to the public, and no reservations are required. Simply show up and enjoy the show!

Saturday February 24 — "The Secret Language of Nature's Tiny Communicators"

  • Presented by: Professor Orit Peleg, Department of Physics and Computer Science, University of Colorado Boulder
  • 2:30 p.m.
  • Abstract: Imagine a world where communication doesn't depend on words, but on flashes of light, scents, and movement. In the extraordinary world of insects, this is a daily reality. This talk will take you on a journey into the secret lives of fireflies and bees, exploring how they convey information through visual and chemical signals. Drawing on concepts from physics, mathematics, and computer science, we will uncover the universal rules that insects obey to make their communication efficient and effective. We'll investigate fireflies, whose twinkling lights allow them to "speak" over vast distances, and bees, who use scents to tell the story of their queen's location. Through a mix of real-world observation and innovative computational techniques, we'll unravel the mysteries behind these intriguing forms of dialogue.

Saturday March 16 — "Quantum computing: what is it and how far along are we?"

  • Presented by: Daniel Slichter, NIST, University of Colorado Boulder
  • 2:30 p.m.
  • Abstract: Imagine if the act of looking at an object caused it to move – or imagine you had a pair of dice that always rolled doubles, but of different numbers each roll. These counterintuitive phenomena are commonplace in the realm of quantum mechanics, which describes systems that are generally very small, very cold, and/or very isolated from the rest of the world. Over the past 40 years, scientists have developed ideas for harnessing the strange features of quantum mechanics to build “quantum computers”, machines where information storage and computation is carried out by objects that behave quantum mechanically. A large-scale quantum computer would in principle be able to perform certain kinds of computations that would be impossible on even the largest classical (i.e. non-quantum) supercomputers. I will describe some of the basics of quantum mechanics and quantum computing, including why it is so technically challenging to build a “useful” large-scale quantum computer. I will also give some perspective on where things stand in the quest for quantum computers that will provide an advantage over existing computing technology.

Saturday April 27 — "Rare earth and other critical elements - their physics, resources, and geopolitics"

  • Presented by: Professor Markus Raschke, University of Colorado Boulder
  • 2:30 p.m.
  • Abstract: The rare earth elements, hidden at the bottom of the periodic table and long neglected, have risen to prominence at the end of the 20th century. Their unique electronic configuration form the basis for a variety of lasers, photonic applications, strong and exotic magnetism, defining many modern technologies. I will tell a story connecting from the basic science of the geology of Colorado and rare earth and other rare element mineralogy, to our technological and societal dependence and questions of strategic element security.

Saturday October 28 — "Enabling Innovation with Measurement Science"

  • Presented by: Dr. Marla L. Dowell, Director, NIST Boulder Laboratory
  • 2:30 p.m.
  • Abstract: From the communications and electronic health records to atomic clocks, advanced nanomaterials and computer chips, innumerable products and services rely in some way on technology, measurement and standards provided by the National Institute of Standards and Technology. What do semiconductor manufacturing, welding, and photodynamic therapy have in common? They all rely on laser measurements for their underlying processes to be effective. We’ll discuss the role of lasers and laser measurements in these different applications. We’ll touch on why a career in physics is a great choice for curious people who like solving technical problems that impact their daily lives.

Saturday November 18 — "The C-PhLARE Project: One Thousand Students vs. the Paradox of the Sun"

  • Presented by: Professor Colin G. West, University of Colorado Boulder
  • 2:30 p.m.
  • Abstract: It is likely both intuitive and familiar that, as you walk further from a campfire, you feel less of its heat. And yet the same is not true for the great fireball in the sky: our sun. In fact, the Sun’s corona is millions of kelvin hotter than its photosphere, despite being much further away from the center of the star. From 2020 through 2021 a team of over a thousand undergraduate students at CU Boulder painstakingly analyzed the X-ray emissions of hundreds of individual solar flares in search of evidence to help resolve this mystery. We'll discuss their findings and conclusions, as well as the novel circumstances that led to this unique collaboration, and the publication of a paper with the most co-authors in the history of The Astrophysical Journal.
