Wave–Particle duality is an interesting concept to think about. Did you know that in 1906 Joseph John Thomson received the Nobel Prize for proving that electrons are particles. And, that his son in 1937 was awarded the Nobel Prize for proving that electrons are waves. And both descriptions correctly describe light. For some this is a paradox. What do you think? This is a Open Thread / Coffee Hour. So, what are you thinking about? What is for dinner? And, how are you today?
Wave–particle duality is the concept that every particle or quantic entity may be partly described in terms not only of particles, but also of waves. It expresses the inability of the classical concepts "particle" or "wave" to fully describe the behavior of quantum-scale objects. As Albert Einstein wrote:
It seems as though we must use sometimes the one theory and sometimes the other, while at times we may use either. We are faced with a new kind of difficulty. We have two contradictory pictures of reality; separately neither of them fully explains the phenomena of light, but together they do.
Although the use of the wave-particle duality has worked well in physics, the meaning or interpretation has not been satisfactorily resolved; see Interpretations of quantum mechanics. — From Wikipedia
Sir Joseph John Thomson; 18 December 1856 – 30 August 1940) was an English physicist and Nobel laureate in physics, credited with the discovery and identification of the electron; and with the discovery of the first subatomic particle.
In 1897, Thomson showed that cathode rays were composed of previously unknown negatively charged particles, which he calculated must have bodies much smaller than atoms and a very large value for their charge-to-mass ratio. — From Wikipedia
Sir George Paget Thomson; 3 May 1892 – 10 September 1975) was an English physicist and Nobel laureate in physics recognised for his discovery of the wave properties of the electron by electron diffraction. — From Wikipedia
