TWO WORLDS. “Classical physics is causal; complete knowledge of the past allows computation of the future. Likewise, complete knowledge of the future allows precise computation of the past. Not so in quantum physics. Objects in quantum physics are neither particles nor waves; they are a strange combination of both. Given complete knowledge of the past, we can make only probabilistic predictions of the future.” https://lnkd.in/ebDJ4MfS View in LinkedIn

MEASUREMENT. “Bohr’s view of quantum mechanics has traditionally been seen as opposed to quantum fundamentalism, not least because he insisted on a classical (not quantum) description of the measurement apparatus. This amounts to dissolving the measurement problem from the outset, since the apparatus and its pointer should not be thought of as being in quantum superpositions.” https://lnkd.in/eauD5rnp View in LinkedIn

SO ENDS this first of two weekends on a consideration of some of Bohr’s ideas about quantum reality. It has been over 100 years since these ideas were introduced, and humanity is still struggling over them. “Opposites are not contradictory but complementary.” (Bohr) sums up how we humans have such deeply embedded and inflexible frames of reference that make understanding the quantum world so difficult. https://lnkd.in/eauD5rnp View in LinkedIn

THE TATTERED HUMAN PSYCHE. “Darwin seems to me to be the Copernicus of the organic world. In the sixteenth century Copernicus put an end to the anthropocentric theory by doing away with the Ptolemaic spheres and bringing our earth down to the rank of an insignificant planet.” (du Bois-Reymond, 1882). https://lnkd.in/e2_HpJsY View in LinkedIn

CONCEPT. “General idea of multipolar bianisotropy. Vector spherical harmonics can be divided into even and odd under inversion operation. Inversion symmetry — No bianisotropy. No inversion symmetry — Bianisotropy.” https://lnkd.in/e5fJZNfb View in LinkedIn

SUMMARY. “We show that the origin of bianisotropy is fully defined by the symmetry of the meta-atom rather than its size.” A strange and mystical paper. https://lnkd.in/e5fJZNfb View in LinkedIn

PAPER. “Electromagnetic Mass and Gravity”, by Professor Valeriy Pakulin, at Saint Petersburg, Russia. A wildly imaginative view of the micro and the macro. https://lnkd.in/eWv3eyi5 View in LinkedIn

AUTHOR. Valeriy Pakulin, Peter the Great St Petersburg Polytechnic University, Russia, list of publications. He follows a Russian physics tradition of being iconoclastic, not following the herd, and coming up with highly original hypotheses, many of which can be tested experimentally. https://lnkd.in/eWKnqJJf View in LinkedIn

TWO COMPONENTS. “Any material body consists of two components: visible and invisible. The visible material component is determined by the mass m. An invisible component is a shell of a material body in the form of an attached vortex of an electromagnetic field medium. The invisible field component is determined by the electromagnetic (relativistic) mass m.” https://lnkd.in/eWv3eyi5 View in LinkedIn
