FIRST HOOK. “On the other hand, in a neural network the elementary degrees of freedom are the excitations of neurons.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=GdPRXs_tGLEAAAAA%3Ag-pxPMtkcleTYDUNK3mYGfpEzKRyc2LqQknTgFFB7dkYFDL8rDe2s0f4_0Q0oKjXD4_AEgFPGWolVTQ View in LinkedIn

POINTS IN TIME. “Those who have succumbed to the seductive allure of the archetype of ‘eternal recurrence’—for example, in our own time: Nietzsche and T.S. Eliot—would want to model points in time by the points on a circle, rather than the real line. In a quantum theory, the scales of time or length are related to the inverse of energy via Planck’s constant.” https://lnkd.in/dMm_YkR View in LinkedIn

STARTING AT THE BEGINNING. “In quantum field framework the elementary degrees of freedom are the quantum oscillators describing the different momentum (and spin/helicity) modes of the field.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=GdPRXs_tGLEAAAAA%3Ag-pxPMtkcleTYDUNK3mYGfpEzKRyc2LqQknTgFFB7dkYFDL8rDe2s0f4_0Q0oKjXD4_AEgFPGWolVTQ View in LinkedIn

EMERGENT TIME. “The idea of the emergence of time is, roughly speaking, that the concept of time as a continuum ordering of events is only an approximation, valid for sufficiently large scales of time and length (and, correspondingly, sufficiently low energies), to what is expected to be a quite different concept in the, as yet, unknown full quantum theory of gravity.” https://lnkd.in/dMm_YkR View in LinkedIn

FIRST TASK. “Our task thus boils down to the need of establishing a dictionary between the states of the quantum fields and the states of the quantum neural networks.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=GdPRXs_tGLEAAAAA%3Ag-pxPMtkcleTYDUNK3mYGfpEzKRyc2LqQknTgFFB7dkYFDL8rDe2s0f4_0Q0oKjXD4_AEgFPGWolVTQ View in LinkedIn

QUANTUM GRAVITY. “The discovery of a satisfactory quantum theory of gravity has been widely regarded as the Holy Grail of theoretical physics for some forty years. The senses in which our standard ideas of time, and more generally spacetime, might be not fundamental to reality, but instead ‘emergent’ as an approximately valid concept on sufficiently large scales.” https://lnkd.in/dMm_YkR View in LinkedIn

GIVEN ASSUMPTIONS. “Although a fully‐satisfactory quantum description of black holes is still missing, it is reasonably clear that they represent the states in a Hilbert space of quantized fields. We shall not question this statement.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=GdPRXs_tGLEAAAAA%3Ag-pxPMtkcleTYDUNK3mYGfpEzKRyc2LqQknTgFFB7dkYFDL8rDe2s0f4_0Q0oKjXD4_AEgFPGWolVTQ View in LinkedIn

FRAGMENT FROM NATURE features an extraordinary article by an extraordinary man. Professor J. Butterfied was Regius Professor of Physic at the University of Cambridge where he led the re-establishment of the School of Clinical Medicine, at the University of Cambridge, and was Master of Downing College, Cambridge. I had a long meeting with this man and was stunned by his extreme gentle humility and his effortless gravitas. https://lnkd.in/dTSsKks View in LinkedIn

INEVITABLE QUESTION. “Let us first ask, what are the black holes from the quantum field theoretic point of view?” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=GdPRXs_tGLEAAAAA%3Ag-pxPMtkcleTYDUNK3mYGfpEzKRyc2LqQknTgFFB7dkYFDL8rDe2s0f4_0Q0oKjXD4_AEgFPGWolVTQ View in LinkedIn

Believe it or not, this little person came up to me in the woods. I am trying to locate its home. Mythical experience. View in LinkedIn
