RUBBISH OR BRILLIANCE. “The wavelengths of light emitted in the glow could be explained, Planck deduced, only by assuming that energy was emitted or absorbed in packets. He worked out the math and showed that the expectations based on his quantum assumption were accurately fulfilled by the light observed in careful experiments. By some accounts, Planck privately suggested that what he had found was either nonsense or one of the greatest discoveries in physics since Newton.” https://lnkd.in/g-p9M-4 View in LinkedIn

SCRATCHING THE SURFACE. “We review here the equation of state of matter in neutron stars from the solid crust through the liquid nuclear matter interior to the quark regime at higher densities. We focus in detail on the question of how quark matter appears in neutron stars, and how it affects the equation of state.” https://lnkd.in/dk9qX6w View in LinkedIn

NEW PHYSICS NEEDED. “The clean identification of several heavy neutron stars, of order two solar masses, challenges our current understanding of how dense matter can be sufficiently stiff to support such a mass against gravitational collapse.” https://lnkd.in/dk9qX6w View in LinkedIn

NEUTRON STARS. “In recent years our understanding of neutron stars has advanced remarkably, thanks to research converging from many directions. The importance of understanding neutron star behavior and structure has been underlined by the recent direct detection of gravitational radiation from merging neutron stars.” https://lnkd.in/dk9qX6w View in LinkedIn

BEYOND OUR GRASP. “A number of years ago we stumbled on the present minimal viscosity explanation for the linear resistivity, playing with the black holes. The qualitative nature of the physics at work is however stunningly different from anything in the condensed matter textbooks. At first encounter, the claims may sound outrageous. The electron fluid in the strange metal is claimed to be governed by hydrodynamics, it flows like water.” https://lnkd.in/dqysHFG View in LinkedIn

EXTRAORDINARY PHYSICS. “The interior of a neutron star, endowed with the highest magnetic fields known and with densities spanning about ten orders of magnitude from the surface to the centre, is predicted to exhibit various phases of dense strongly interacting matter, whose physics is reviewed in this chapter.” https://lnkd.in/dm-4wAJ View in LinkedIn

COSMIC LABS. “Formed in the aftermath of gravitational core-collapse supernova explosions, neutron stars are unique cosmic laboratories for probing the properties of matter under extreme conditions that cannot be reproduced in terrestrial laboratories.” https://lnkd.in/dm-4wAJ View in LinkedIn

The first violets of the year emerge coincident with almond blossom and the first mosquito, in a sudden rush with an upsurge in warm weather. Life will find a way! View in LinkedIn

SOCIAL BEINGS. “The memory of the multitude is thus made up from human-archival entanglements of communication through digital devices and networks. For better or for worse, such entanglements are today irresistibly part of what it means to be social.” https://lnkd.in/dWiV2eZ View in LinkedIn

“DEEP MACHINE LEARNING is based not on symbols, rules, or procedures such as “if this, then that” but on exposure of many examples to layered networks of artificial neurons that have thousands of connections with one another. It has been shown that such systems can, without supervision, form generalizations of patterns that recur in the examples.” https://lnkd.in/dzHM-4X View in LinkedIn
