Modern topics in physics curriculum

Click For Summary
SUMMARY

The discussion centers on the need to incorporate modern physics topics into introductory physics curricula. Key topics identified include blackbody radiation, the photoelectric effect, de Broglie's matter waves, and the standard model of particles. Participants emphasize the importance of presenting these concepts in accessible language rather than complex mathematics. The current curriculum is criticized for focusing predominantly on historical physics discoveries, which limits students' exposure to contemporary scientific advancements.

PREREQUISITES
  • Understanding of basic physics concepts
  • Familiarity with the historical context of physics discoveries
  • Knowledge of key figures in physics such as Einstein and Bohr
  • Awareness of the significance of modern physics in scientific education
NEXT STEPS
  • Research the implications of blackbody radiation in modern physics
  • Explore the educational approaches to teaching the photoelectric effect
  • Investigate the role of de Broglie's matter waves in quantum mechanics
  • Study the standard model of particles and its impact on contemporary physics
USEFUL FOR

Physics educators, curriculum developers, and students interested in modern physics advancements and their integration into educational frameworks.

1. Question end an explanation of it:
Which modern topics that are the result of modern physics discovery would you like to see in the classroom?

Current curriculum is mostly ancient physics and explains ancient discoveries.
Those are essential for understanding the basics of physics, but they leave no room for modern discoveries.

Which in your opinion are these modern topics that you'd like to see teachers teach - explain in classrooms - expecialy as a part of intrudustory physics?

Since the question is a part of my homework research as a masters degree student, but involves intruductory physics, I'm posting it here.

Thank you for your opinion!

As it is now, books and courses called "Modern Physics" mean, by that term, the entire 20th century.

Some of the biggies are blackbody radiation, Planck and the photon, photoelectric effect, Compton effect, de Broglie's matter waves, wave equation, Born's interpretation of the wave equation, uncertainty, Bohr's modification of the Rutherford atom, Bohr explanation of spectra, exclusion principle, statistical mechanics, solid state, nuclear forces and decay and reactions, standard model of particles, Lorentz and Einstein and relativity, cosmology.

In my opinion: as much of it as possible in plain English, and as little as possible in the form of mathematics.

P.S. I think this forum topic is in the wrong category.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
