Physical Review D The polynomial form of the scattering equations is an -basis The calculation of scattering amplitudes for an arbitrary number of scattering particles in quantum field theories is a very challenging task. Within the so-called scattering equation framework, the authors propose a new way to evaluate scattering amplitudes by exploiting an equivalent polynomial form of the scattering equations.

The Constant e What is e? "e" is a numerical constant that is equal to 2.71828. Just as pi (3.14159) is a numerical constant that occurs whenever the circumference of a circle is divided by its diameter. e is usually defined by the following equation: Its value is approximately 2.718 and has been calculated to 869,894,101 decimal places by Sebastian Wedeniwski. An effective way to calculate the value of e is not to use the defining equation above, but to use the following infinite sum of factorials. e = 1/0! As an example, here is the computation of e to 22 decimal places: The sum of the values in the right column is 2.7182818284590452353602875 which is "e."

About PhysicsQuest PhysicsQuest is a story-based activity that exposes middle school students to the fun and relevance of science. APS provides a free PhysicsQuest kit to registered 6-9th grade physical science classes, home school groups, science clubs, and after-school programs. The kit includes a user's manual and materials for four physics experiments. PhysicsQuest aims to teach middle school students physics concepts, but its overarching goal is to give them a positive experience with physics. APS is focusing this program on middle school students because these grades have been identified as the point when many students lose interest in math and science. PhysicsQuest began as a World Year of Physics 2005 project with a kit based on Albert Einstein. The past five versions of PhysicsQuest have combined kits with comic books that follow the adventures of our original laser superhero, Spectra. PhysicsQuest Staff Teacher Feedback “My students don't like science BUT this was an activity they really enjoyed!”
This new equation might finally unite the two biggest theories in physics, claims physicist One of the most stubborn problems in physics today is the fact that our two best theories to explain the Universe - general relativity and quantum mechanics - function perfectly well on their own, but as soon as you try to combine them, the maths just doesn’t work out. But a Stanford theoretical physicist has just come up with a new equation that suggests the key to finally connecting the two could be found in bizarre spacetime tunnels called wormholes. The equation is deceptively simple: ER = EPR. It’s not made up of numerical values, but instead represents the names of some key players in theoretical physics. On the left side of the equation, the ER stands for Einstein and Nathan Rosen, and refers to a 1935 paper they wrote together describing wormholes, known technically as Einstein-Rosen bridges. On the right side of the equation, EPR stands for Einstein, Rosen and Boris Podolsky, who co-wrote another paper that year describing quantum entanglement. Okay, now let’s combine the two.

Occam's razor The sun, moon and other solar system planets can be described as revolving around the Earth. However that explanation's ideological and complex assumptions are completely unfounded compared to the modern consensus that all solar system planets revolve around the Sun. Ockham's razor (also written as Occam's razor and in Latin lex parsimoniae) is a principle of parsimony, economy, or succinctness used in problem-solving devised by William of Ockham (c. 1287 - 1347). It states that among competing hypotheses, the one with the fewest assumptions should be selected. Other, more complicated solutions may ultimately prove correct, but—in the absence of certainty—the fewer assumptions that are made, the better. Solomonoff's theory of inductive inference is a mathematically formalized Occam's Razor:[2][3][4][5][6][7] shorter computable theories have more weight when calculating the probability of the next observation, using all computable theories which perfectly describe previous observations.
Boriska – This Fascinating Boy From Russia Remembers His Past Life on Mars Boris Kipriyanovich who goes by Boriska meaning “little Boris”, is an incredibly gifted boy from Zhirinovsk, Russia. He was born in 1996 and ever since he was 4 years old he would visit a mountain known as Medvedetskaya Gryada in order to recharge himself from the world. Often times children who present themselves with sensitive gifts find refuge in nature and Boriska was no different. Boriska’s mother, being a doctor, noticed right away that he was stronger and developed quicker than other children. At the age of 1 Boriska could read newspaper headlines and at the age of 2 he learned how to draw. 6 months after learning to draw he began to paint as well. Boriska Was Learning Otherworldly Skills as well On top of learning and growing up much quicker than all of the students around him, Boriska was also learning things from otherworldly sources that left his parents baffled. “No one has ever taught him,” Boriska’s mother stated.
