R211 EINSTEIN’S RELATIVITY *

OLLI program: OLLI Online Course location: UD OLLI Online (virtual) Wednesday 10:45 a.m. - noon Dates of class: 2/9/2022 - 4/27/2022 Instructor: Charles Carter Number of class sessions: 11 • Price for course: $50 Course format: Lecture, Video Based Technological requirements for optimal viewing: Audio & video with monitor/screen of 12” or more

Why should E=mc2? Does this equation only apply to atomic bombs and nuclear reactions? Can a person travel to a distant star and return home within a lifetime? Is time travel possible? What is the total energy in the universe? Potential answers to such questions are found in Einstein’s special and general theories of relativity. This course explores the logic behind these theories, structured as a combination of lectures and relevant videos. A minimal amount of high school algebra is used.

R203 THE GENIUS OF RICHARD FEYNMAN *

OLLI program: Wilmington Course location: Arsht Hall, Wilmington Thursday 10:45 a.m. - noon Dates of class: 2/10/2022 - 4/28/2022 Instructors: Saul Reine, Tom Keane Number of class sessions: 11 • Price for course: $70 Course format: Discussion, Lecture, Active (Hands-on/ physical movement), Video Based

This course will follow the life and career of Richard Feynman using his lectures, videos and documentaries. His genius enabled him to introduce us to fields of science and technology years before they became mainstream, with diagrams that simplified physics problems. He predicted the importance of nanotechnology while we were still figuring out the macro world, and his work on quantum electrodynamics earned him a Nobel prize. And yes, he played the bongos!

R210 PALEONTOLOGY 101 *

OLLI program: Wilmington Course location: Arsht Hall, Wilmington Tuesday 10:45 a.m. - noon Dates of class: 2/8/2022 - 5/10/2022 Instructor: William A. Jones Number of class sessions: 13 • Price for course: $70 Course format: Lecture, Video Based

Please join us for a 4.5 billion years trip through the development of the earth, plants and animals. We will learn how paleontologists determine how, what and where fossils should be placed on the earth’s timeline. Extinctions and their possible causes will also be discussed.

R215 SYMMETRY, PROBLEMS AND PUZZLES

OLLI program: Kent/Sussex Course location: Trinity Faith Education Bldg., Lewes Tuesday 10:45 a.m. - noon Dates of class: 2/8/2022 - 3/8/2022 • Class limit: 32 Instructor: Dean Hoover Number of class sessions: 5 • Price for course: $25 Course format: Discussion

In this course I plan to present a collection of puzzles and problems from my past courses, including a discussion about the present state of symmetry in math. Everyone in the class will be given a puzzle that they may take home. Please come and enjoy the fun!

R213 TELESCOPES—TIME MACHINES OF DISCOVERY

OLLI program: Kent/Sussex Course location: Trinity Faith Education Bldg., Lewes Monday 9 a.m. - 10:15 a.m. Dates of class: 2/7/2022 - 3/7/2022 • Class limit: 40 Instructor: Jim O’Leary Number of class sessions: 5 • Price for course: $25 Course format: Lecture

Telescopes are time machines peering into the history of the universe, providing sights and understanding not otherwise possible. But at its simplest, it consists of two small pieces of glass in a tube. Follow the telescope’s evolution, see a reproduction of Galileo’s first telescope and view the beautiful images from the Hubble Space Telescope. We’ll explore the exotic, remote locations of new, large telescopes, including those in space, revealing a new and spectacularly beautiful cosmos. This hybrid-format course meets as two distinct but concurrent sections, one in-person, one online. In-person participants may join in the online class when their schedule requires.

R213-06 TELESCOPES—TIME MACHINES OF DISCOVERY

OLLI program: Kent/Sussex Course location: UD OLLI Online (virtual) Monday 9 a.m. - 10:15 a.m. Dates of class: 2/7/2022 - 3/7/2022 • Class limit: 40 Instructor: Jim O’Leary Number of class sessions: 5 • Price for course: $25 Course format: Lecture Technological requirements for optimal viewing: Any screen with audio and video

This section is offered online. Same as R213 except for location. Due to space constraints, students enrolled in the online section do not hold a seat in the in-person class. Register for the appropriate section. Technical requirements are listed for online participation.

R204 UNDERSTANDING THE QUANTUM WORLD PART 2 *

OLLI program: OLLI Online Course location: UD OLLI Online (virtual) Tuesday 12:30 p.m. - 1:45 p.m. Dates of class: 2/8/2022 - 4/26/2022 • Class limit: 45 Instructors: Bruce Neff, Howard Barth Number of class sessions: 11 • Price for course: $50 Course format: Discussion, Lecture, Video Based Technological requirements for optimal viewing: Audio & video with monitor/screen of 12” or more

Quantum mechanics is the most successful physical theory known in science. This essentially nonmathematical course is geared for the science enthusiast who is interested in understanding the quantum nature of matter and how it is used in physical science and technology. We also examine bizarre behavior in the quantum realm.
