What Is Quantum Teleportation? - Quanta Magazine
Mar 14, 2024 · Teleporting people through space is still science fiction. But quantum teleportation is dramatically different and entirely real. In this episode, Janna Levin interviews the theoretical physicist John Preskill about teleporting bits and the promise of quantum technology.
How the Higgs Field (Actually) Gives Mass to Elementary Particles
Sep 3, 2024 · This notion lies at the heart of what the late British physicist Peter Higgs, namesake of the Higgs field, and his competitors pointed out in the 1960s: that one field can stiffen other fields, thereby permitting their ripples to vibrate in place with a resonant frequency, and thus giving their particles mass.

Why Euler’s Number Is Just the Best | Quanta Magazine
Nov 24, 2021 · Last month, we presented three puzzles that seemed ordinary enough but contained a numerical twist. Hidden below the surface was the mysterious transcendental number e.Most familiar as the base of natural logarithms, Euler’s number e is a universal constant with an infinite decimal expansion that begins with 2.7 1828 1828 45 90 45… (spaces added to highlight the quasi-pattern in the first ...
A Mathematician’s Guided Tour Through High Dimensions
Sep 13, 2021 · This all adds up to an intuitive understanding that an abstract space is n-dimensional if there are n degrees of freedom within it (as those birds had), or if it requires n coordinates to describe the location of a point. Yet, as we shall see, mathematicians discovered that dimension is more complex than these simplistic descriptions imply.
New Clues for What Will Happen When the Sun Eats the Earth
Dec 20, 2023 · Earth’s fate rests on a coin flip. In 5 billion years, our sun will balloon into a red giant star. Whether Earth survives is an “open question,” said Melinda Soares-Furtado, an astrophysicist at the University of Wisconsin, Madison.Sure, Earth …
How Earth’s Climate Changes Naturally (and Why Things Are …
Jul 21, 2020 · Faint Young Sun. Magnitude: No net temperature effect. Time frame: Constant. Though the sun’s brightness fluctuates on shorter timescales, it brightens overall by 0.009% per million years, and it has brightened by 48% since the birth of the solar system 4.5 billion years ago.. Scientists reason that the faintness of the young sun should have meant that Earth remained frozen solid for the ...
‘Milestone’ Evidence for Anyons, a Third Kingdom of Particles
May 12, 2020 · Fermions are the antisocial members of the particle world. They never occupy the same quantum state. Because of this, electrons, which are fermions, get forced into the varied atomic shells around an atom.
A New Map of All the Particles and Forces | Quanta Magazine
Oct 22, 2020 · This approach doesn’t offer insight into the relationships between the particles. The force-carrying particles (namely the photon, which conveys the electromagnetic force; the W and Z bosons, which convey the weak force; and the gluons, which convey the strong force) are put on the same footing as the matter particles those forces act …
Insects and Other Animals Have Consciousness, Experts Declare
Apr 19, 2024 · The new declaration, signed by biologists and philosophers, formally embraces that view. It reads, in part: “The empirical evidence indicates at least a realistic possibility of conscious experience in all vertebrates (including all reptiles, amphibians and fishes) and many invertebrates (including, at minimum, cephalopod mollusks, decapod crustaceans and insects).”
