The Mathematical Structure of Particle Collisions Comes Into View

Posted by in categories: computing, information science, mathematics, particle physics, quantum physics

And that’s where physicists are getting stuck.

Zooming in to that hidden center involves virtual particles — quantum fluctuations that subtly influence each interaction’s outcome. The fleeting existence of the quark pair above, like many virtual events, is represented by a Feynman diagram with a closed “loop.” Loops confound physicists — they’re black boxes that introduce additional layers of infinite scenarios. To tally the possibilities implied by a loop, theorists must turn to a summing operation known as an integral. These integrals take on monstrous proportions in multi-loop Feynman diagrams, which come into play as researchers march down the line and fold in more complicated virtual interactions.

Physicists have algorithms to compute the probabilities of no-loop and one-loop scenarios, but many two-loop collisions bring computers to their knees. This imposes a ceiling on predictive precision — and on how well physicists can understand what quantum theory says.

Magellanic Stream arcing over Milky Way may be five times closer than previously thought

Posted by in categories: futurism, space

Our galaxy is not alone. Swirling around the Milky Way are several smaller, dwarf galaxies—the biggest of which are the Small and Large Magellanic Clouds, visible in the night sky of the Southern Hemisphere.

During their dance around the Milky Way over billions of years, the Magellanic Clouds’ gravity has ripped from each of them an enormous arc of gas—the Magellanic Stream. The stream helps tell the history of how the Milky Way and its closest galaxies came to be and what their future looks like.

New astronomical models developed by scientists at the University of Wisconsin–Madison and the Space Telescope Science Institute recreate the birth of the Magellanic Stream over the last 3.5 billion years. Using the latest data on the structure of the gas, the researchers discovered that the stream may be five times closer to Earth than previously thought.

Singapore’s Tech Utopia Dream Has Become a Surveillance State Nightmare

Posted by in categories: law enforcement, robotics/AI, surveillance, transportation

This new reality promises robotic dogs to enforce social distancing and publicly owned flying taxis to provide transportation since private vehicles are only available to the rich. The technology is currently being rolled out in other western nations, including Canada.

On a hard disk somewhere in the surveillance archives of Singapore’s Changi prison is a video of Jolovan Wham, naked, alone, performing Hamlet.

Researchers Bundle 24 400mm Lenses into Massive Telescope Array

Posted by in category: cosmology

24 Canon lenses strapped together with the power of a refracting telescope 1.8 meters in diameter.


An international team of researchers has bundled groups of 24 Canon EF 400mm f/2.8 lenses together into what they call the Dragonfly Telephoto Array in order to capture photos of distant stars.

The Dragonfly Telephoto Array is a telescope that is equipped with multiple Canon 400mm f/2.8L IS II USM lenses. The telescope array was designed in 2013 by the team, also named Project Dragonfly, which is an international research team from Yale University and the University of Toronto. The Dragonfly Telephoto Array is capable of capturing images of galaxies that are so faint and large that they had escaped detection by even the largest conventional telescopes. Its mission is to study the low surface brightness universe to elucidate the nature of dark matter and to utilize the concept of distributed telescopes.

Meet the Fish That Grows Up in Just 14 Days

Posted by in categories: biotech/medical, life extension, neuroscience

😳! Circa 2018


Some animals live fast and die young. That means they need to grow up fast, too. This week, researchers crowned a new record holder for quick growth: Susan Milius at Science News reports that the turquoise killifish, Nothobranchius furzeri, found in Mozambique, can reach maturity in just 14 days, the fastest of any known vertebrate animal.

That rapid maturation is an adaptation to the killifish’s habitat, according to the study published this week in the journal Current Biology. The fish spend most of their lives as tiny embryos that have been deposited in sediment in small depressions across the savannah. When rain fills the ephemeral pools, the embryos mature rapidly reaching sexual maturity and depositing their own embryos before the pool once again dries up. Not only do they make babies quickly, they bulk up fast, too—typically growing from about 5 millimeters to 54 millimeters in their lifespan.
