INCORRECT ASSUMPTION. “Bohr’s viewpoint, it would mean to assert that an object in itself is a quantum system. An obvious suggestion would be to think that the deep nature of objects is correctly represented by quantum wave functions. But Bohr could not have supported this idea.” https://lnkd.in/eauD5rnp View in LinkedIn

ELUSIVE REALITY. “Bohr emphasizes what one can say about nature, and rejects the question of how nature is in itself. This is consistent with the fact that Bohr almost always stresses epistemological rather than ontological aspects of quantum mechanics.” https://lnkd.in/eauD5rnp View in LinkedIn

HIGHER DIMENSIONALITY. “Bohr noted among other things that the quantum wave function in general “lives” in a mathematical space with more than the usual three dimensions.” https://lnkd.in/eauD5rnp View in LinkedIn

NOT ABOUT REALITY. “When asked whether the algorithm of quantum mechanics could be considered as somehow mirroring an underlying quantum world, Bohr would answer, "There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about nature.” https://lnkd.in/eauD5rnp View in LinkedIn

DIVIDED WORLD. “Thus, the apparatus and its pointer are always in definite positions. However, Bohr’s idea seems to be problematic as it suggests that there is a separate classical realm of reality. And it is not at all clear how one could divide up the world in a classical and a quantum part.” https://lnkd.in/eauD5rnp View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on a discussion of some of Bohr’s ideas about the quantum reality. Bohr differed from mainstream thinkers in being more nuanced and inclusive and less dogmatic. The reality is that many quantum ideas are simply beyond our ability to imagine them as concepts, since they seem mutually contradictory. https://lnkd.in/eauD5rnp View in LinkedIn

WHAT IS ENERGY? “Energy is not made of anything. It's a fundamental concept closely related to time. That's because energy just represents change in a system. Ultimately, we observe systems to change in time. We've developed a concept called energy to account for the amount of change.” https://lnkd.in/eJNmi9i7 View in LinkedIn

SO ENDS this one of many highly unorthodox theoretical papers from the Russian physics tradition. This particular author is highly original in his views and always fun to read. https://lnkd.in/eWv3eyi5 View in LinkedIn

RADICAL. “The Earth does not attract the Moon. The pressure of the interplanetary medium of the electromagnetic field pushes the Moon towards the Earth.” https://lnkd.in/eWv3eyi5 View in LinkedIn
