Gravitational Wave Research Reveals Missing Details on The Mysterious Antikythera Mechanism

Posted by in categories: computing, physics

Little more than a handful of corroded bronze wheels and heavily encrusted gears now remains of the ancient artifact called the Antikythera mechanism, leaving archaeologists to speculate over its functionality and purpose.

After decades of study, it’s largely agreed that the millennia-old device was something of an analog computer capable of keeping track of celestial movements. Yet with only fractured fragments to go by, researchers can only guess at the more intricate methods of its operation.

Researchers from the University of Glasgow in the UK have now used statistical modeling techniques borrowed from the study of gravitational waves to extrapolate missing details of a critical dial on Antikythera mechanism.

CNC Dialogues — Georg Northoff & Aldrich Chan: Space, Time, Self & Consciousness

Posted by in categories: physics, space

Dr. Georg Northoff is a neuroscientist, psychiatrist, and philosopher holding doctorates in all three disciplines. In this episode, we begin by discussing the self, and consciousness. We then enter into a dialogue about what he terms the world-brain problem, in contrast to the mind-body problem. He shares what he means by the neuroecological approach, why space and time are central to understanding the mind, and how it has foundational implications to diagnosis, treatment and research. We then talk about the practical implications of his viewpoint, for laymen and professionals alike. We follow by pivoting to cover topics such as the importance of philosophy in science, his stance on free will, and a series of rapid fire bonus questions that you don’t want to miss out on. We end on a review of his journey into becoming an MD, Ph.D, his future projects and words of wisdom for anyone listening. I invite you to skip around if you find any of these topics of particular interest to you.

Can a computer chip have zero energy loss in 1.58 dimensions?

Posted by in categories: computing, mobile phones, physics

What if we could find a way to make electric currents flow, without energy loss? A promising approach for this involves using materials known as topological insulators. They are known to exist in one (wire), two (sheet) and three (cube) dimensions; all with different possible applications in electronic devices.

Theoretical physicists at Utrecht University, together with experimentalists at Shanghai Jiao Tong University, have discovered that topological insulators may also exist at 1.58 dimensions, and that these could be used for energy-efficient information processing. Their study was published in Nature Physics.

Classical bits, the units of computer operation, are based on : electrons running means 1, no electrons running means 0. With a combination of 0’s and 1’s, one can build all the devices that you use in your daily life, from cellphones to computers. However, while running, these electrons meet defects and impurities in the material, and lose energy. This is what happens when your device gets warm: the energy is converted into heat, and so your battery is drained faster.

Physicists Have Created The World’s Most Fiendishly Difficult Maze

Posted by in category: physics

Daedalus could have learned a thing or two from a team of physicists in the UK and Switzerland.

Taking principles from fractal geometry and the strategic game of chess, they have created what they say is the most fiendishly difficult maze ever devised.

Led by physicist Felix Flicker of the University of Bristol in the UK, the group has generated routes called Hamiltonian cycles in patterns known as Ammann-Beenker tilings, producing complex fractal mazes that, they say, describe an exotic form of matter known as quasicrystals.

CERN’s ATLAS experiment releases 65 TB of open data for research

Posted by in categories: education, energy, physics

The ATLAS Experiment at CERN has made two years’ worth of scientific data available to the public for research purposes. The data include recordings of proton–proton collisions from the Large Hadron Collider (LHC) at a collision energy of 13 TeV.

This is the first time that ATLAS has released data on this scale, and it marks a in terms of public access and utilization of LHC data.

Scientists observe record-setting electron mobility in a new crystal film

Posted by in categories: physics, sustainability, transportation

A material with a high electron mobility is like a highway without traffic. Any electrons that flow into the material experience a commuter’s dream, breezing through without any obstacles or congestion to slow or scatter them off their path.

The higher a material’s electron mobility, the more efficient its , and the less energy is lost or wasted as electrons zip through. Advanced materials that exhibit high electron mobility will be essential for more efficient and sustainable electronic devices that can do more work with less power.

Now, physicists at MIT, the Army Research Lab, and elsewhere have achieved a record-setting level of electron mobility in a thin film of ternary tetradymite—a class of mineral that is naturally found in deep hydrothermal deposits of gold and quartz.

What happened in Big Bang — new theory, new state of matter

Posted by in categories: computing, cosmology, physics

Physicists have proposed a new theory: in the first quintillionth of a second, the universe may have sprouted microscopic black holes with enormous amounts of nuclear charge.

For every kilogram of matter that we can see — from the computer on your desk to distant stars and galaxies — there are 5kgs of invisible matter that suffuse our surroundings. This “dark matter” is a mysterious entity that evades all forms of direct observation yet makes its presence felt through its invisible pull on visible objects.
