The figure illustrates three events in Minkowski spacetime. Event 𝐵 is neither in the past nor in the future of 𝐴, 𝐴 ∼ 𝐵, and event 𝐶 is neither in the past nor in the future of 𝐵, 𝐵 ∼ 𝐶. Despite this, 𝐶 ≁ 𝐴. Indeed, 𝐶 is in the future of 𝐴: 𝐶Continue reading “Past Future Second…”

Ripples in Spacetime…
Topics: Astrophysics, High Energy Physics, Particle Physics Each week Quanta Magazine explains one of the most important ideas driving modern research. This week, physics staff writer Charlie Wood explains why many researchers are looking to outer space for signs of “new physics.” Fundamental physics has a problem. Some researchers say the field faces a “nightmareContinue reading “Ripples in Spacetime…”

Colleagues remember Peter Higgs as an inspirational scientist, who remained humble despite his fame. Credit: Graham Clark/Alamy Topics: CERN, Higgs Boson, High Energy Physics, Nobel Prize, Particle Physics, Quantum Mechanics, Theoretical Physics Few scientists have enjoyed as much fame in recent years as British theoretical physicist Peter Higgs, the namesake of the boson that was discoveredContinue reading “Nanos Gigantum Humeris Insidentes…”

Image source: Link below Topics: Applied Physics, Astrophysics, Computer Modeling, Einstein, High Energy Physics, Particle Physics, Theoretical Physics In the search for new physics, a new kind of scientist is bridging the gap between theory and experiment. Traditionally, many physicists have divided themselves into two tussling camps: the theorists and the experimentalists. Albert Einstein theorizedContinue reading “In Medias Res…”
Grappling With Waste…
The underground Onkalo repository in Finland is designed to safely and permanently store hazardous, radioactive waste. Credit: Posiva Topics: Environment, High Energy Physics, Nuclear Power Finland and the former Yugoslavia adopted nuclear energy only four years apart. In 1971 Finland began construction of its first nuclear plant, Loviisa, and the first of two planned reactorsContinue reading “Grappling With Waste…”
X-rays, Bond Breaks, and Climate…
An X-ray flash illuminates a molecule. Credit: Raphael Jay Topics: Chemistry, Climate Change, Green Tech, High Energy Physics, Research, X-rays The use of short flashes of X-ray light brings scientists one big step closer to developing better catalysts to transform the greenhouse gas methane into a less harmful chemical. The result, published in the journal Science,Continue reading “X-rays, Bond Breaks, and Climate…”
Rule Breakers…
Credit: Matt Harrison Clough (original image at link) Topics: Entanglement, High Energy Physics, Particle Physics, Quantum Mechanics Breaking the rules is exciting, especially if they have been held for a long time. This is true not just in life but also in particle physics. Here the rule I’m thinking of is called “lepton flavor universality,”Continue reading “Rule Breakers…”
Weighty W…
Topics: Fermilab, High Energy Physics, Modern Physics, Particle Physics, Steven Weinberg The most precise measurement to date of the mass of the W boson has yielded a result seven standard deviations away from that predicted by the Standard Model of particle physics. The stunning result was obtained by a painstaking analysis of data taken atContinue reading “Weighty W…”
DUNE…
Topics: Fermilab, High Energy Physics, Modern Physics, Neutrinos, Particle Physics Solving big mysteries The Deep Underground Neutrino Experiment is an international flagship experiment to unlock the mysteries of neutrinos. DUNE will be installed in the Long-Baseline Neutrino Facility, under construction in the United States. DUNE scientists will paint a clearer picture of the universe and how itContinue reading “DUNE…”
Collider Neutrinos…
Topics: CERN, High Energy Physics, Particle Physics, Research Think “neutrino detector” and images of giant installations come to mind, necessary to compensate for the vanishingly small interaction probability of neutrinos with matter. The extreme luminosity of proton-proton collisions at the LHC, however, produces a large neutrino flux in the forward direction, with energies leading toContinue reading “Collider Neutrinos…”
