String theory and our conceptions of reality - Culturico

Mar 22, 2021The first was a theory in which space and time are replaced by vibrating strings, leading to the superstring theory of Michael Green (Queen Mary London) and John Schwarz (CalTech) (4). The second, inspired by Roger Penrose in Oxford (5), was the development of twistor theory, replacing the points (events) of space-time with light rays.

String Theory: The de Broglie Hypothesis - dummies

The de Broglie hypothesis states that particles of matter also had wavelengths and could behave as waves, just as photons did. String theory will later say that both types of particles — matter and energy — are manifestations of vibrating strings, but that's about 50 years down the road from de Broglie's time. He proposed his theory in 1923.

Vibration screens for dewatering — Theory and practice

In addition to classifying bulk material, vibration screens are commonly used in dewatering. However, the lack of a comprehensive physical theory of dewatering often leads to difficulties in the design and operation of the vibration screens. First, in this report, the dewatering of bulk material are shown based on a physical model. Because of the oscillatory motion of the liquid in the bulk ...
