Is it not good to know what follows from what, even if it is not necessarily FAPP? [FAPP is Bell's suggested abbreviation of 'for all practical purposes.'] Suppose for example that quantum mechanics were found to resist precise formulation. Suppose that when formulation beyond FAPP was attempted, we find an unmovable finger obstinately pointing outside the subject, to the mind of the observor, to the Hindu scriptures, to God, or even only Gravitation? Would that not be very, very interesting?

While the founding fathers agonized over the question 'particle' or 'wave', de Broglie in 1925 proposed the obvious answer 'particle' and 'wave'. Is it not cle…

The concept of 'measurement' becomes so fuzzy on reflection that it is quite surprising to have it appearing in physical theory at the most fundamental level..…

Theoretical physicists live in a classical world, looking out into a quantum-mechanical world. The latter we describe only subjectively, in terms of procedures…

The quest of the absolute leads into the four-dimensional world.

Although the problem of transmuting chemical elements into each other is much older than a satisfactory definition of the very concept of chemical element, it …
