Negative Energy Alec Li, Sydney Osugi Period 2, AP Physics  The term positive energy encompasses light, matter and antimatter. While positive energy is created through the collision of electrons and their positron counterparts, collisions with negative energy and matter result in nothing. Negative energy is the concept that there is a region of space that is able to “contain less than nothing … can be less than zero”(`Negative Energy'' Solutions: Hole Theory). The law of the conservation…

work so much so that any book establishing that the earth moved was banned, starting in 1616. This was the first step on a long road still being made in science. Following Copernicus’s work, Galileo and Kepler began their own works in astrology and physics, including the creation of the telescope and the debunking of the Aristotelian theory of “heavier bodies fall faster than lighter ones,” (Okasha, 4). The years after Galileo died, the scientific revolution really began to pick up speed. With…

In chemistry it is expected that pupils be taught about ‘the nature of matter, about the atom, chemical reactions, the periodic table and the Earth and the atmosphere’. In physics, the basics of physics should be taught, including; ‘energy, motion and forces, waves, electricity and electromagnetism, matter and space physics’. (DFE, 2013) KS4 content is a continuation and build-up of the principles and ideas that are introduced in KS3. At this level, more insight and analytical…

Science has revolutionized our world with unimaginable advancements in technology. From the brilliant minds of William Whewell (who coined the English word “science”) to the modern day scientist like Stephen William Hawking (who contributed to the vast amount of today’s knowledge on cosmology and quantum gravity). Furthermore, science has become so advanced in this day-in-age that it has been split apart into different sections that each cover a broad range of technological information,…

Referee’s Report JOSA B Manuscript ID 273944 PAPER DESCRIPTION In the paper titled “Non-Markovian coherence and entanglement transfer in a quantum version of Newton’s cradle”, Mu and co-author have presented the quantum analog of the classical Newton’s cradle. An array of couple cavities (coupled with a common Markovian and non-Markovian environment) with nearest neighbor hopping interaction between the cavities, has been selected as the quantum cradle. In the case of quantum cradle with…

Charles Dodgson was the real name of the author who wrote Alice’s Adventures in Wonderland and the sequel Through the Looking Glass. For his writing he went under the pen name Lewis Carroll. Along with writing he was also an English logician, mathematician, and photographer. He had a lot of siblings; 7 girls and 4 boys were born to his parents. He was the third child born and their oldest son. He also went through a lot of illnesses, one left him deaf in one ear. He had a stutter, but Carroll…

A man travels in the Yukon on a tremendously cold morning with a husky. The cold does not faze the man, even though he is new to Yukon, who plans to meet his friends by six o 'clock at an old claim. The philosophy of naturalism is that matter is the one and only thing to exist. Naturalism also your mind is just a physical phenomenon based on the function of physical and chemical actions. Throughout reading this short story it is very prominent the use of nature is clear. The ways at which…

Identity has always been a problem in society. People create terms or stereotypes that become the identity of another individual. The 1985 movie The Breakfast Club showed the effects that stereotypes have on people. The five main characters were coined as a criminal, jock, basket case, brain, and princess (The Breakfast Club). All of these names that are supposed to represent their identity turned out to be wrong. At the end of the movie, the audience saw that every character was more than their…

Brahmagupta and His Significant Discovery Brahmagupta was born in 598 in Rajasthan, India and he was an Indian astronomer that may not get all the credit he deserves. Being an orthodox Hindu, he was very interested in the Hindu yuga system that focused on the measurement of the ages of mankind. Even though he mostly devoted his time to Indian astronomy, Brahmagupta when writing his books implemented a great amount of mathematics. This was seen especially in his most famous work…

In Abraham Pais’s article, “What Happened in Copenhagen?: A Physicist's View and the Playwright's Response,” Pais argues the historical accuracy of Michael Frayn’s 1998 play, Copenhagen. Frayn’s play depicts a meeting that took place in 1941 between prominent physicist Niels Bohr and Werner Heisenberg. The play takes place is the Nazi occupied Denmark, and sheds light on the political issues both men are facing. Following Pais’s dispute regarding small details of the play, Frayn then gives his…
