CLIMATE RISKS: DEEP DIVE INTO CARBON CAPTURE TECHNIQUES UD OLLI Online (R240–06) Monday 12:45–2 p.m. 2/5/2024–3/4/2024 Instructor: William Haaf Number of class sessions: 5 • Class limit: 290 Course format: Discussion, Lecture The scientific consensus is overwhelming. Earth and, especially, the oceans are getting hotter. China, America, India and the EU should quickly transition to minimal greenhouse gas (GHG) emissions to avoid catastrophic climate impact. Construction of solar and wind technologies is progressing slowly, held back by an old electric grid and complex rules and politics. Carbon capture presents opportunities and risks. We review varied technologies and path-forward strategies.
EINSTEIN’S RELATIVITY* Arsht Hall, Wilmington (R211–01) Monday 12:45–2 p.m. 2/5/2024–5/6/2024 UD OLLI Online (R211–06) Monday 12:45–2 p.m. 2/5/2024–5/6/2024 Instructor: Charles Carter Number of class sessions: 13 Course format: Lecture, Video Based 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 the special and general theories of relativity. This course explores the logic behind these theories. A minimal amount of high school algebra is used. This is a hybrid-online course: one section meets on site; one is online only. See page 3 for details.
