Physicists puzzled by strange numbers that could explain reality

Eight-dimensional octonions may hold the clues to solve fundamental mysteries.

 

  • Physicists discover complex numbers called octonions that work in 8 dimensions.
  • The numbers have been found linked to fundamental forces of reality.
  • Understanding octonions can lead to a new model of physics.

Is our reality, including its forces and particles, based on the strange properties of numbers with eight dimensions called “octonions“? A physicist thinks so, having found a way to expand 40-year-old research to reach surprising new directions.

First, a brief history of numbers.

Physicists solve a 140-year-old mystery

 

  • Researchers discover a method of extracting previously unavailable information from superconductors.
  • The study builds on a 19th-century discovery by physicist Edward Hall.
  • The research promises to lead to a new generation of semiconductor materials and devices.

 

New research, led by IBM, made a breakthrough in resolving a mystery that has baffled physicists for 140 years. It promises to lead to a new generation of semiconductor materials and devices that use them.

Ligação química entre átomos é registrada pela primeira vez; veja vídeo

Cientistas fizeram registro sem querer. Fenômeno microscópico ocorre em escala 500 mil vezes menor que a espessura de um fio de cabelo

 

Pela primeira vez na história, cientistas da Universidade de Nottingham, na Inglaterra, filmaram átomos rompendo e formando ligações químicas. O fenômeno microscópico ocorre em uma escala muito pequena, entre 0,1 e 0,3 nanômentro — o que é 500 mil vezes menor que a espessura de um fio de cabelo.

Physicists Finally Observe a Link Between Quantum Criticality And Entanglement

We know that the realm of quantum physics is science operating at a mind-bogglingly small scale, thus watching quantum interactions happen is always exciting. Now, physicists have managed to observe billions upon billions of entangled electrons passing through a metal film.

The film is a mix of ytterbium, rhodium and silicon, and is what’s known as a ‘strange metal’, one that doesn’t act as expected at very low temperatures.

“With strange metals, there is an unusual connection between electrical resistance and temperature,” explained physicist Silke Bühler-Paschen from Vienna University of Technology in Austria.

“In contrast to simple metals such as copper or gold, this does not seem to be due to the thermal movement of the atoms, but to quantum fluctuations at the absolute zero temperature.”

These fluctuations represent a quantum criticality – that point between quantum states which are the equivalent of transition between liquids, solids and gases in classical physics; the team says this cascade of electrons is the best evidence yet of a link between quantum criticality and entanglement.

Immune cell that kills most cancers discovered by accident by British scientists

British scientists have accidentally discovered a new type of cell that kills most cancers. The new discovery could be a huge breakthrough in the search for a universal cure for cancer, writes British newspaper The Telegraph.

new type of immune cell which kills most cancers has been discovered by accident by British scientists, in a finding which could herald a major breakthrough in treatment.

Researchers at Cardiff University were analysing blood from a bank in Wales, looking for immune cells that could fight bacteria, when they found an entirely new type of T-cell.

That new immune cell carries a never-before-seen receptor which acts like a grappling hook, latching on to most human cancers, while ignoring healthy cells.

In laboratory studies, immune cells equipped with the new receptor were shown to kill lung, skin, blood, colon, breast, bone, prostate, ovarian, kidney and cervical cancer.

Meditation’s Effects on Alpha Brain Waves

A new study out of Brown University has found that a form of mindfulness meditation known as MBSR may act as a “volume knob” for attention, changing brain wave patterns.

What is MBSR?
Originally developed by a professor at the University of Massachusetts Medical School, mindfulness based stress reduction (MBSR) is based on mindfulness meditation techniques that have been practiced in some form or another for over two millennia. The 8-week MBSR program still follows some of the same principles of the original Buddhist practice, training followers to focus a “spotlight of attention” on different parts of their body. Eventually, it is hoped, practitioners learn to develop the same awareness of their mental states.

In the last 20 years, MBSR and a similar practice called mindfulness based cognitive therapy (MBCT) have been included in an increasing number of healthcare plans in the developed world. Some studies have shown that these practices can reduce distress in individuals with chronic pain and decrease risk of relapses into depression.

How reading makes you more intelligent and empathic

Get lost in a good book. Time and again, reading has been shown to make us healthier, smarter, and more empathic.

Fitness headlines promise staggering physical results: a firmer butt, ripped abs, bulging biceps. Nutritional breakthroughs are similar clickbait, with attention-grabbing, if often inauthentic—what, really, is a “superfood?”—means of achieving better health. Strangely, one topic usually escaping discussion has been shown, time and again, to make us healthier, smarter, and more empathic animals: reading.

Reading, of course, requires patience, diligence, and determination. Scanning headlines and retweeting quips is not going to make much cognitive difference. If anything, such sweet nothings are dangerous, the literary equivalent of sugar addiction. Information gathering in under 140 characters is lazy. The benefits of contemplation through narrative offer another story.
