The Fifth Force

“Now therefore write ye this song for you, and teach thou it the children of Israel.” Deut. 31:19 The four known fundamental forces are: gravitational force, electromagnetic force, strong (nuclear) force and weak (betta decay) force. Newton first described gravitational force in his famous universal law of gravity. Today, we use Einstein’s General Theory of Relativity to describe strong gravitation fields. Electromagnetism was described in the 19 c. by Faraday and Maxwell. Strong and week forces were discovered much later, in the second half of the 20 c. Since Albert Einstein started a search for a unified field theory, unsuccessfully trying to unify (describe by a single theory) gravity and electromagnetism, the quest for a unified field theory – the “Theory of Everything” – became the holy grail of theoretical physics. Strong and [...]

Four Camps at Sea – Four Fundamental Interactions

  On the penultimate day of the Passover Holidays (which is called Shvii shel Pesach – the Sevenths Day of Passover), we read in the Torah about Kriat Yam Suf – splitting of the sea.  The Talmud (Yerushalmi Pesachim) and Midrash (Pirka deRabeinu Hakadosh) tells us that at that dramatic moment, when the Jews, who just escaped Egypt, were trapped between the sea and the Egyptian army pursuing them, the Jews were divided into four camps (so many Jews and only four opinions?!), each advocating a different course of action: one group proposed to wage a war with Egyptians; the other group wanted to jump into the sea; the third group advocated prayer and the fourth insisted on returning to Egypt.
