A popular science lecture delivered in English and Hebrew to general audiences of students and the general public, describing the incredible features and history of the lightest and most elusive known fundamental particle in nature and its role in cosmology, astrophysics and particle physics. The English version here is from a symposium in Tel Aviv University (May 2005) in honor of the 80th birthday of the late Professor Yuval Ne'eman.
A Popular Science lecture about particle physics, delivered in 2004, to a general audience, at the Weizmann Institute, on the occasion of the 50th anniversary of the Physics Department.
This is a lecture delivered to a general audience at Stanford, on the occasion of the 40th anniversary of the Stanford Linear Accelerator Center (SLAC). It covers many significant developments in the field of Particle Physics during the years 1962-2002, with an emphasis on the 1970s when SLAC was at center stage.
A video of a lecture given in 2000 (still with a Viewgraph) in a conference in honor of Burton Richter's departure from his directorship of SLAC.
In 1994 the Israeli Instructional TV has produced a five-part series of popular science programs (in Hebrew) covering "100 years of physics, and how they changed our lives". The concept of the series, the script and the narration were done by Haim Harari. Several of these programs won international awards. Since the science part of the series relates to the historic steps in the pursuit of the structure of matter, the Hebrew name of the series is חומר למחשבה translatable into English as "A matter of thought".
The five-part series chapters are:
(i) The electrified Atom
(ii) Cracking Nuclei
(iii) Magnetic personality
(iv) Supreme Forces
(v) A guest from another star

A popular science article discussing the possibility that the most fundamental known particles in nature (the electron, the quarks, the neutrino, and others) are not at all fundamental and are composed of smaller objects. The article is almost 40 years old but the problems posed have not been solved and very little, if anything, has happened since then, that might change the arguments presented. There is no evidence for or against such sub-particles and the systematic pattern that need to be explained is still unexplained.
Answer: The Electron, the Quark, and the Neutrino are Composite Objects.
Answer: The Higgs (God’s?) Particle Closes a Chapter? No Way.
Answer: The Next Level of Fundamental Matter?
Answer: Harari’s Law of Science Education; Harari’s Law of Particle Physics; Harari’s Law of Scientific Fads and Bandwagons.
A short article (in Hebrew) on the analogy between basic research and the childhood of a person. The article was published in the Hebrew popular science Magazine "Galileo".
