The election year highlighted the growing problem of wealth inequality and finding ways to help the people who are falling behind.

This human urge of compassion isn't new, but the big question that remains to be addressed is why inequality is so difficult to erase. This inspired Adrian Bejan, the J. Bejan's Constructal Law addresses the fundamental principle of physics that underlies the evolution of flow systems as they change in design over time to increase flow access. It reveals that "branching tree-shaped" flow patterns govern the structure of the entire universe—most clearly evident within rivers, neural networks, lightning bolts, electrical circuitry and trees.

They demonstrate this via two architectures: river basins and the movement of freight. Bejan explains that the "emerging physical flow architecture is hierarchical on Earth's surface and found in everything that flows inside human bodies, the movement of humans and their belongings, and the engines that drive the movement. So why has wealth inequality been notoriously difficult to erase? Also recognize movement wealth as inequality that is hierarchical.

A Level Physics: AQA: 2017 (Full A Level): Paper 1: Section A

This finding is "pivotal for physics, because it shows that the economics concept of wealth has a physical basis, which is measurable as work, fuel consumed, or movement effected by fuel, food, and work," he elaborated. The equivalence between wealth and movement is correct in the broadest sense: outliers exist and undoubtedly the equivalence is evolutionary because wealth and fuel use are increasing over time.

Inequality is a negative term, and perhaps isn't the best word to describe the distribution of wealth. One of the central concepts involved in Bejan and Errera's work is hierarchy, which occur when many small items and a few large ones flow together versus flowing in competition with each other.

Picture a river basin with its many small tributaries flowing together to a few large rivers—the Mississippi, Missouri and Ohio. Before becoming an engineer, Bejan was a basketball star in Romania, and from the "live flow system" of the basketball court he learned that "the ball flows through non-rigid channels that are hierarchical and constantly morphing," he said.

Constructal Theory":. Every flow architecture on Earth follows the same order, which is a natural tendency to want to flow more easily. What did they discover in terms of wealth inequality? Bejan and Errera show that nonuniform distribution of movement wealth becomes more accentuated as an economy becomes more developed—its flow architecture becomes more complex for the purpose of covering smaller and smaller interstices of the overall territory.

Physics can predict wealth inequality

As wealth in the world becomes increasingly unbalanced, Bejan's hope is that his work proposes the possibility of empowering people more uniformly to reduce the glaring disparity of wealth often on display within cities or rural areas. It's a complex design that involves the evolution of the rule of law. In other words: government and other organizations stepping in, which historically has happened," Bejan said.

The time given at the head of this Paper is the time allowed for writing the answers.December 8, Aalto University doctoral student Juska Pekkanen is part of a group working with the highest collision energies ever achieved.

The work at the CERN research centre in Switzerland became widely known when the Nobel-prize-winning discovery of the Higgs boson completed the standard model of particle physics. What Pekkanen and thousands of other physicists at CERN do now, is explore phenomena that fall beyond the current understanding of the sub-atomic world.

For instance, only 15 per cent of the mass of the entire universe can be accounted for now with normal visible matter, the rest is dark matter of which there's very little knowledge. An equally shrouded mystery is dark energy that makes the universe expand and pushes celestial bodies away from each other. One way to do this, is to make protons — the nuclei of hydrogen atoms — collide at tremendously high speeds and energies, and study what comes out of the crashes.

Pekkanen and his colleagues have focused on particle bursts called 'jets' that are born when protons collide. These events could contain faint signs of completely new particles.

Virtually every collision produces jets, or bursts of tens of particles that consist of quarks and gluons. Researchers count the total energy in the jets and measure how their energy is carried by different kinds of particles.

The more accurate we get with our measurements, the easier it becomes to discover new particles," says Pekkanen. The thousands of signals that some of the millions of sensors pick up have to be sorted with complex algorithms. By recreating the events with computer simulations, the sensors can be fine-tuned. Jets could, according to Pekkanen, also be key in finding new massive particles.

He has focused on events where a collision of particles produces two jets that burst into opposite directions. We analyse billions of these collisions and see if we spot any abnormalities that could be a sign of revolutionary new particle," explains Pekkanen.

The study makes use of the highest energy level ever achieved in the Large Hadron Collider: 13 teraelectronvolts. For a single proton that's quite a lot, roughly the kinetic energy of a mosquito flying. Count all the proton energies together: enough to fly a jumbo jet.

The experiments will continue: By the end ofthe physicists expect to collect up to ten times more data. This means there's a need for designing the next generation of hadron colliders and detectors to reach even higher energies — and hopefully long-awaited new physics. More from Other Physics Topics.

It took 1. The signal was extremely weak when it reached Earth, but is already promising a revolution in astrophysics. Gravitational waves are an entirely new way of observing the most violent events in space and testing the limits of our knowledge. LIGO, the Laser Interferometer Gravitational-Wave Observatoryis a collaborative project with over one thousand researchers from more than twenty countries.

Together, they have realised a vision that is almost fifty years old. Pioneers Rainer Weiss and Kip S. Thornetogether with Barry C.

Barishthe scientist and leader who brought the project to completion, ensured that four decades of effort led to gravitational waves finally being observed. In the mids, Rainer Weiss had already analysed possible sources of background noise that would disturb measurements, and had also designed a detector, a laser-based interferometer, which would overcome this noise.

Early on, both Kip Thorne and Rainer Weiss were firmly convinced that gravitational waves could be detected and bring about a revolution in our knowledge of the universe.

Gravitational waves spread at the speed of light, filling the universe, as Albert Einstein described in his general theory of relativity.

They are always created when a mass accelerates, like when an ice-skater pirouettes or a pair of black holes rotate around each other. Einstein was convinced it would never be possible to measure them. So far all sorts of electromagnetic radiation and particles, such as cosmic rays or neutrinos, have been used to explore the universe. However, gravitational waves are direct testimony to disruptions in spacetime itself. This is something completely new and different, opening up unseen worlds.

College football Week 11 predictions Three top educational research matchups are on the slate along with four other top 25 matchups as Week 11 of the 2017 season promises to shake up the College Football Playoff rankings next week.

The Argentine side were never truly in difficulty in this tournament, and against the side that won the title against them in the previous edition they will want to prove that was just a mistake.

We are betting on Vargas and Sanchez to explode the Colombian defense and see their side through to the final. However, the team that tripped up Brazil in their Copa America opener (0-0) can count on their defensive qualities to hold their own in the contest. Yet it might take more than this combination to get past a Columbian side well seasoned to international competitions. If their recent results and form on the pitch are anything to go by, it stands to reason that their quarter final should see them dispose with ease of a valiant but technically limited Venezualan side.

Their last two wins (3-0 and 5-0) showed the offensive potential of the team and reassured on its ability to keep a clean sheet. Based on their recent record, Mexico advance into this quarter final with more confidence than their opponents.

Yet it is hard to imagine a team like like Chile not pulling itself together 3 games from a continental final. The title holders have the squad to make it to the end, its just a matter of when they realize their potential on the field.

Despite the near-touchdown spread, this week has seen the most people picking against the Eagles since they went into Carolina in Week 6 as a three-point underdog, a game they won by five points. By comparison, the Birds were also six-point favorites the last time they played on the road (Week 11 at Dallas), and almost nobody outside of Cowboys fans was picking against them. With a win, the Birds will win 10 straight in a single season for the first time in franchise history.

The question is, will they. You can check that out, here. This is not the same Seahawks team you remember over the last five years.

The Seahawks can no longer bulldoze defenses with Marshawn Lynch, and they're missing both Richard Sherman and Kam Chancellor on the back end defensively.

I think this is the next in line of teams that gets exposed by a superior Eagles roster.

Full disclosure: I do not enjoy watching the Eagles try to handle Russell Wilson. Without Richard Sherman, I think the Seahawks are vulnerable enough for the Eagles to take down. They lost to the dang Redskins, guys. These are the games they brought Jay Ajayi in for. Expect Doug Pederson to go to Ajayi and Blount early and often, and for Philadelphia to grind out a tough victory.

I'm not going to spend a lot of time with analysis here, because the more I think about this game, the closer I come to second-guessing my prediction. It's just one of those games. The last time I felt like this was Week 6 against the Panthers.

I picked a 27-23 Eagles' win then too, and they won 28-23. Also, the Redskins won in Seattle just a few weeks ago and, I mean, did you watch that game on Thursday night.Lonely and just want to chat.

See Example( s )In August 2015, a video claiming that episodes of the Fox animated series The Simpsons had made some eerily accurate predictions about future events began circulating via social media.

Most notable among those predictions was a clip purportedly taken from a 2000 episode that showed business magnate Donald Trump announcing his candidacy for President of the United States:I want people to realize the synchronicity here and all the connections. This was put out in 2000. Now this is happening. While the above-displayed video touches on a wide variety of Simpsons related conspiracy theories, the main issue was highlighted in September 2015 with a photograph one that not only documented that The Simpsons had depicted Donald Trump running for President back in 2000, but that they did so by showing him in a setting and pose (riding an escalator while waving to supporters and onlookers) identical to one he would assume fifteen years later:The images from The Simpsons shown on the left-hand side of the above-displayed graphic did not originate in 2000, however.
