An Invited 2022 keynote speech

An invited keynote speech at the 2022 Physics and Astronomy World Forum, Valencia, Spain, November 14, entitled What The Universe Consists of: Material Points or Continuous Fields, addresses the unification of basic concepts of quantum field theory and elementary quantum mechanics. Here is the powerpoint file. Following is the main reference cited by that talk:

The Natural Quantum Mechanics, a textbook of elementary quantum mechanics based on the all-field view of quantum field theory. Chapters 1 through 7.

An Invited 2021 keynote speech

A keynote speech at the 2021 Physics and Astronomy World Forum, Frankfurt, December 3, entitled Wavefunction is an Observable Physical Field, addressing the problem of fundamental understanding of quantum mechanics, in view of the experimental observation and mapping of atomic and molecular wavefunctions using scanning tunneling microscopy. Here is the powerpoint file. Following is the main reference cited by that talk:

Imaging Wavefunctions, Chapter 8 of Introduction to Scanning Tunneling Microscopy, Third Edition. Oxford University Press, January 29, 2021.

 

 

An invited plenary speech at the 2022 World ENT Congress
