A new physics discovery could change the game for quantum computing

From tunneling through impenetrable barriers to being in two places at the same time, the quantum world of atoms and particles is famously bizarre. Yet the strange properties of quantum mechanics are not mathematical quirks—they are real effects that have been seen in laboratories over and over.

One of the most iconic features of quantum mechanics is “entanglement”—describing particles that are mysteriously linked regardless of how far away from each other they are. Now three independent European research groups have managed to entangle not just a pair of particles, but separated clouds of thousands of atoms. They’ve also found a way to harness their technological potential.

When particles are entangled they share properties in a way that makes them dependent on each other, even when they are separated by large distances. Einstein famously called entanglement “spooky action at a distance,” as altering one particle in an entangled pair affects its twin instantaneously—no matter how far away it is.

Google Doodle Honors Mathematician Johann Carl Friedrich Gauss

A German mathematician, physicist and astronomer, Johann Carl Friedrich Gauss rose from humble origins to become one of the world’s greatest minds.

Born in 1777 in Brunswick, then part of the Holy Roman Empire, Gauss was the only child of poor parents who had received little or no formal education. His mother was illiterate. But when Gauss started school at age seven, he was quickly recognized as a child prodigy who could solve complex math problems in his head.

While still a teenager, Gauss became the first person to prove the Law of Quadratic Reciprocity, a math theory to determine whether quadratic equations can be solved.

Felix Klein and the Klein-Bottle

On April 25, 1849, German mathematician and mathematics educator Felix Klein was born. Klein is known for his work in group theory, complex analysis, non-Euclidean geometry, and on the connections between geometry and group theory. His 1872 Erlangen Program, classifying geometries by their underlying symmetry groups, was a hugely influential synthesis of much of the mathematics of the day. Klein also devised the Klein-bottle, a one-sided surface which, if traveled upon, could be followed back to the point of origin while flipping the traveler upside down.

A mathematician named Klein Thought the Möbius band was divine. Said he: “If you glue The edges of two, You’ll get a weird bottle like mine.” ( Leo Moser )

Felix Klein’s father was an old Prussian Protestant from Ennepetal in southern Westphalia. He was district administrator of the government’s main fund in Düsseldorf, while Klein’s mother came from industrial circles in Aachen. In the autumn of 1865 Felix Klein began studying mathematics and natural sciences at the University of Bonn. Klein studied in Bonn with Rudolf Lipschitz and Julius Plücker, whose assistant he became. After Plucker’s death Alfred Clebsch took over the publication of his unfinished work and transferred this work to the talented Klein received his doctorate in 1868 from Plücker with a topic from geometry applied to mechanics. In 1869 he went to Berlin University and listened to a lecture by Leopold Kronecker on square forms.[5] He took part in the mathematical seminars of Ernst Eduard Kummer and Karl Weierstrass, where he also met Sophus Lie, with whom he went to Paris for a study visit in 1870 and was a friend.

Scientists Discover How to Harness the Power of Quantum Spookiness

Happy birthday Aubrey de Grey

Happy birthday to dr. aubrey de grey bigsmile

How many biologists does it take to make nontrivial progress on an unsolved mathematical problem for the first time in nearly 70 years? The answer is one, at least if the biologist is Dr. Aubrey de Grey, the pioneer of the repair approach to aging.

Yes, you read that right. Today, in occasion of Dr. de Grey’s birthday, we’ve decided to take a short break from biology and rejuvenation to tell our readers about the recent scientific achievement of one of the world’s most famous biogerontologists—unexpectedly, but pleasantly so, in the field of mathematics.

The chromatic number of the plane

Don’t worry if mathematics is not really your thing; we’ll keep it simple. Imagine that you have an infinitely large plane, where all points located at distance 1 from one another are connected by a straight line; any number of so-connected points, finitely or infinitely many, is called a graph. Further suppose that, for some reason, you wanted to color each point in such a fashion that no two connected points have the same color. How many different colors would you need to do this for the entire plane?

Memory Successfully Boosted In Humans

Scientists from Wake Forest Baptist Medical Center partnered with researchers from the University of Southern California to develop an innovative procedure to give hope to people struggling with remembering important information. A new implant uses a person’s own memory patterns in order to boost the brain’s natural ability to encode those memories and recall them quickly. There has been a reported 35 to 37 % increase in short-term memory performance.

“This is the first time scientists have been able to identify a patient’s own brain cell code or pattern for memory and, in essence, ‘write in’ that code to make existing memory work better, an important first step in potentially restoring memory loss,” said the study’s lead author Robert Hampson, Ph.D., professor of physiology/pharmacology and neurology at Wake Forest Baptist.

Epilepsy patients from Wake Forest Baptist were surgically implanted with electrodes in the various parts of their brains. The electronic prosthetic system is based on a multi-input-multi-output (or MIMO) mathematical model to influence the patterns of neurons firing within the hippocampus.

New algorithm will allow for simulating neural connections of entire brain on future exascale supercomputers

Amazing.

An international team of scientists has developed an algorithm that represents a major step toward simulating neural connections in the entire human brain.

The new algorithm, described in an open-access paper published in Frontiers in Neuroinformatics, is intended to allow simulation of the human brain’s 100 billion interconnected neurons on supercomputers. The work involves researchers at the Jülich Research Centre, Norwegian University of Life Sciences, Aachen University, RIKEN, KTH Royal Institute of Technology, and KTH Royal Institute of Technology.

An open-source neural simulation tool. The algorithm was developed using NEST (“neural simulation tool”) — open-source simulation software in widespread use by the neuroscientific community and a core simulator of the European Human Brain Project. With NEST, the behavior of each neuron in the network is represented by a small number of mathematical equations, the researchers explain in an announcement.

Mad Scientists Want to 3D Print Every Dead Person Back to Life

This major religious site suggests I’m part of a group of mad scientists, but Quantum Archaeology is a very interesting idea that more people should ponder. The article also highlights the challenge of #transhumanism vs. religion and conservative attitutes: http://www.lifenews.com/2018/03/12/mad-scientists-want-to-3-…k-to-life/ #transhumanism

But the self-described secular transhumanist is perfectly serious in his posturing about the future of technology, life and death. Within 50 years, he believes scientists may be able to bring back people from the dead.

“After all, everything is matter and energy. And human life, human thoughts and human existence are mathematical, determinable calculations of that subatomic world of matter and energy,” Istvan writes.

“As a secular transhumanist—someone who advocates for improving humanity by merging people with machines—I don’t believe in death anymore,” he continues. “Most transhumanists’ number one goal is to become immortal through science.”

Though he does not lump himself into this camp, he says some transhumanists want to bring back every life who ever lived.

The Largest Number Of Scientists In Modern U.S. History Are Running For Office In 2018

At least 200 candidates with previous careers in science, technology, engineering and math announced bids for some of the nation’s roughly 7,000 state legislature seats as of Jan. 31, according to data that 314 Action, a political action committee, shared exclusively with HuffPost.

This comes at a time when there’s only one Ph.D. scientist in Congress.
