The Fundamental Patterns that Explain the Universe — with Brian Clegg

Posted by in categories: business, mathematics, military, quantum physics, time travel

From the cosmic microwave background to Feynman diagrams — what are the underlying rules that work to create patterns of action, force and consequence that make up our universe?
Brian’s new book “Ten Patterns That Explain the Universe” is available now:
Watch the Q&A:

Brian Clegg will explore the phenomena that make up the very fabric of our world by examining ten essential sequenced systems. From diagrams that show the deep relationships between space and time to the quantum behaviours that rule the way that matter and light interact, Brian will show how these patterns provide a unique view of the physical world and its fundamental workings.

A New Theory for Systems That Defy Newton’s Third Law

Posted by in categories: energy, mathematics, physics, singularity, transportation

Many of these systems are kept out of equilibrium because individual constituents have their own power source — ATP for cells, gas for cars. But all these extra energy sources and mismatched reactions make for a complex dynamical system beyond the reach of statistical mechanics. How can we analyze phases in such ever-changing systems?

Vitelli and his colleagues see an answer in mathematical objects called exceptional points. Generally, an exceptional point in a system is a singularity, a spot where two or more characteristic properties become indistinguishable and mathematically collapse into one. At an exceptional point, the mathematical behavior of a system differs dramatically from its behavior at nearby points, and exceptional points often describe curious phenomena in systems — like lasers — in which energy is gained and lost continuously.

Now the team has found that these exceptional points also control phase transitions in nonreciprocal systems. Exceptional points aren’t new; physicists and mathematicians have studied them for decades in a variety of settings. But they’ve never been associated so generally with this type of phase transition. “That’s what no one has thought about before, using these in the context of nonequilibrium systems,” said the physicist Cynthia Reichhardt of Los Alamos National Laboratory in New Mexico. “So you can bring all the machinery that we already have about exceptional points to study these systems.”

Why don’t solar-powered cars exist?

New AI improves itself through Darwinian-style evolution

Posted by in categories: information science, mathematics, robotics/AI

AutoML-Zero is unique because it uses simple mathematical concepts to generate algorithms “from scratch,” as the paper states. Then, it selects the best ones, and mutates them through a process that’s similar to Darwinian evolution.

AutoML-Zero first randomly generates 100 candidate algorithms, each of which then performs a task, like recognizing an image. The performance of these algorithms is compared to hand-designed algorithms.-Zero then selects the top-performing algorithm to be the “parent.”

“This parent is then copied and mutated to produce a child algorithm that is added to the population, while the oldest algorithm in the population is removed,” the paper states.

Tetris Handheld Powered By Tritium Cell, Eventually

Posted by in categories: cybercrime/malcode, mathematics, nuclear energy, solar power, sustainability

The idea of a tritium power cell is pretty straightforward: stick enough of the tiny glowing tubes to a photovoltaic panel and your DIY “nuclear battery” will generate energy for the next decade or so. Only problem is that the power produced, measured in a few microwatts, isn’t enough to do much with. But as [Ian Charnas] demonstrates in his latest video, you can eke some real-world use out of such a cell by storing up its power over a long enough period.

As with previous projects we’ve seen, [Ian] builds his cell by sandwiching an array of keychain-sized tritium tubes between two solar panels. Isolated from any outside light, power produced by the panels is the result of the weak green glow given off by the tube’s phosphorus coating as it gets bombarded with electrons. The panels are then used to charge a bank of thin-film solid state batteries, which are notable for their exceptionally low self-discharge rate.

PARADOX LOST: The Public Edition

Posted by in categories: cosmology, government, mathematics, particle physics, time travel

“PARADOX LOST: The Public Edition, by Marshall Barnes,” Oct 6, 2014.

This book is by internationally noted research and development engineer, Marshall Barnes, and is based on his special report for select members of the United States Congress on the coming reality of time travel, which is now here on the particle level. The only authoritative book on the subject of time travel, it scientifically answers all the issues around the topic, proves why paradoxes are impossible and why the world’s physicists have been so wrong about time travel for so long. Includes definitive analysis of errors by Stephen Hawking, Kip Thorne, Paul Davies, Tim Maudlin, among others. Answers Kurt Godel’s famous question of how can a past that hasn’t passed yet, be the past, and many other issues left unanswered by all other sources.

Among outstanding features, it details Marshall’s creation of the Verdrehung Fan™, the first time machine in the world, that is sending signals through traversable micro wormholes, as speculated could be possible in New Scientist magazine, May 20th, 2014. The Einstein related physics from which it works and how Marshall used it to defeat world famous Ronald Mallett in the race to build a time machine, is revealed as well as why Mallett is far less than the media has made him seem.

Easy to read but rich in detail, this book will be a challenge for scientist and non-scientist alike, with preconceived notions about the subject, as all cliches are dismantled and discarded, revealing stunning, hidden truths that are reached without ever taking a step off the path of known physics. This is the book for those wanting definitive answers backed by definitive proofs and calculations, without dealing with the heavy mathematics.

Examining recent developments in quantum chromodynamics

Posted by in categories: engineering, mathematics, particle physics, quantum physics

Created as an analogy for Quantum Electrodynamics (QED) — which describes the interactions due to the electromagnetic force carried by photons — Quantum Chromodynamics (QCD) is the theory of physics that explains the interactions mediated by the strong force — one of the four fundamental forces of nature.

A new collection of papers published in The European Physical Journal Special Topics and edited by Diogo Boito, Instituto de Fisica de Sao Carlos, Universidade de Sao Paulo, Brazil, and Irinel Caprini, Horia Hulubei National Institute for Physics and Nuclear Engineering, Bucharest, Romania, brings together recent developments in the investigation of QCD.

The editors explain in a special introduction to the collection that due to a much stronger coupling in the — carried by gluons between quarks, forming the fundamental building blocks of matter — described by QCD, than the , the divergence of perturbation expansions in the mathematical descriptions of a system can have important physical consequences. The editors point out that this has become increasingly relevant with recent high-precision calculations in QCD, due to advances in the so-called higher-order loop computations.

Criticizing Starship (Part Three)

Posted by in categories: cybercrime/malcode, finance, government, internet, mathematics, space travel

He has done his math. The questions seem to be: How to put together viable payloads to make use of Stsrship launches? How to build new markets in space?

This again?! Game Over? Busted? We’re doing Starship again so soon because I’m an unoriginal hack. There’s also been new developments in Starship and I think it’s a perfect time to revisit the launch system. Get as mad as you wish.
