The Solvay physics conferences resumed in 1948, and this version was held in Brussels, Belgium. This chapter provides the strict view expressed by David Bohm fits with the description provided by A. Einstein. After the 1933 Solvay conference, the conferences were suspended, not to be begun again until after the coming global conflagration. The field exploded with earth shaking effects, but in the postwar world of quantum mechanics, work by Bohm would create a fire storm. Einstein attempted to explain more thoroughly his objections to the completeness of quantum mechanics. Bohm put together his causal theory after being unhappy with the general state of quantum mechanics as he found it during the time he was writing his book. Bohm goes on to criticize the usual interpretation of quantum theory on his fundamental approach. The usual interpretation of quantum mechanics takes little accord of the particle and the origin of the interference becomes difficult to understand.
