You do know that Velikovsky's "work" is inflammatory pseudo-science though, right?
The fundamental criticism against this book from the astronomy community was that its celestial mechanics were irreconcilable with Newtonian celestial mechanics, requiring planetary orbits which could not be made to conform to the laws of conservation of energy and conservation of angular momentum (Bauer 1984:70). Velikovsky conceded that the behavior of the planets in his theories is not consistent with Newton's laws of motion and universal gravitation. He proposed that electromagnetic forces could be the cause of the movement of the planets, although such forces between astronomical bodies are essentially zero (Friedlander 1995:11-12).
Velikovsky tried to protect himself from criticism of his celestial mechanics by removing the original Appendix on the subject from Worlds in Collision, hoping that the merit of his ideas would be evaluated on the basis of his comparative mythology and use of literary sources alone. However this strategy did not protect him: the appendix was an expanded version of the Cosmos Without Gravitation monograph, which he had already distributed to Shapley and others in the late 1940s—and they had regarded the physics within it as egregious.
See, what happened was, Sigmund Freud had pissed off the orthodox religious community by (among many things) suggesting that the character of Moses was based on the Egyptian father of monotheism, Akhenaton. Velikovsky began playing literary games with history to refute the Head Shrink, in a blatantly satirical manner, by "proving" that Moses happened nowhere near the scholarly accepted date and that furthermore, Akhenaten was actually the basis for the character of Oedipus. Get it?
Brilliant, sure. Truthful? Serious? Hardly. Science? Not even close.
From 1924 to 1939 Velikovsky lived in what was then the British Mandate of Palestine, practising medicine (both general practice and psychiatry), and also psychoanalysis (he had studied under Sigmund Freud's pupil, Wilhelm Stekel in Vienna). During this time he had a dozen or so papers published in medical and psychoanalytic journals, including, in 1930, the first paper to suggest that epilepsy is characterised by abnormal encephalograms, now part of the routine diagnostic procedure, and papers in Freud's Imago, including a precocious analysis of Freud's own dreams.
