Quantum field theory

Introduction There are 2 major theories about the universe and how it began. These are the steady state and The Big Bang theory. Both theories have an explanation on how our Universe is, how it began and how it works. Both theories have stuff in common but also have many differences that could completely change the way we look at the Universe. The Big Bang Theory has much more evidence supporting it, while the Steady State Theory has been proven wrong. Big Bang Theory The Big Bang Theory first…

Interpretation of the NOESY: (Nuclear Overhauser Effect) spectrum of 1-(2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)azepan-2-one (3a) is as follows. Strong coupling interaction of protons of 2nd and 4th position in 1-(2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)azepan-2-one (3a), was not so strongly observed in COSY because it involves long range coupling i.e. protons attached between 2nd and 4th carbon atom. Hence, we studied NOESY to know the spacial interaction between these two protons. Thus, the…

Jean Jacques Rousseau was a Swiss born philosopher. His father was an educated watchmaker. His mother died at childbirth and his father was exiled from Geneva. He had a hard time living with his mother's family. At the age of 16, he fled Geneva and went to France. Paris was culturally very different from Geneva. He suffered from deep isolation and his life was very unstable. He was involved in many strange affairs with women. However, he met a woman named Mme de Warens who was 10 years older…

Evie McCormack Mr. Acland B Block Physics Lab: Speed of Sound Essential Question Asked: How does the speed of sound differ between metals and gases? Background Information: The speed of sound is gauged by distance over time (distance/time). Certain aspects that can change or affect the speed of sound would include the density of the item through which the sound is traveling. Continuing on with that concept, when sound is…

same direction as the magnetic force and decreases when the current is at 90° to the magnetic force [1]. With the growing demands for higher HDD storage density, other forms of MRs with larger variances of resistance due to applied external magnetic fields were needed to be discovered. Two main forms of MRs are: Tunnel Magneto Resistance (TMR) Giant Magneto Resistance (GMR) In year 1936Mott suggested that Spin-polarized currents can be generated by exploiting the influence of…

WERNHER VON BRAUN Wernher Magnus Maximilian Freiherr von Braun, the father of modern rocketry and one of the most important outer space engineers of the 20th century, was born on 23th of March 1912 in Wirsitz (Wyrzysk)(today in Poland). He was a child of a wealthy family from Germany. With their second son, Wernher, Magnus von Braun and Emmy von Quistorp moved to Berlin in 1915. In those years, Wernher von Braun became interested in music and astronomy. And his passion, astronomy, went on for…

Atoms are the most basic building blocks, everything around us are made out of atoms. Atoms are so small that it can’t be found under the finest microscopes. A tiny spec of dust contains millions of billions of atoms! Even though atoms are tiny, but it actually consist of three different particles: protons, neutrons, and electrons. In every atom, electrons move around the nucleus, the combination of protons and neutrons. The idea of an atom was first discovered by the ancient Greeks, they…

The mathematician that i pick was Albert Einstein March 14, 1879- April 18, 1955 . He was a very smart and intelligent man who had many great ideas that has had an impact on the world today. The reason i picked him is because although he had a slight disability, he was still very successful in life and was one of the most known people from the past. Not only was he wise in math, but he was also very wise in mathematics. Albert Einstein had a very different but unique personality and way of doing…

which would have allowed him to study for a diploma at the Eidgenössische Technische Hochschule in Zurich. He made a plan of graduating as a teacher in mathematics and physics. He got his PHD in 1905. He also created the theory of relativity. A lot of people thought that his theory was wrong but gamma rays prove that he was right. In 1921 he won the nobel prize in physics, for his work on the photoelectric effect. he thought that light consisted of particles called protons. The speed of of…

has been the goal for many great scientists. Through centuries of experimenting, the mid-evil era of alchemy, and many years after, Chemistry became a topic of much importance. During the 1800’s, science had become one of the most rapidly growing fields as explanations for how things work, or the technological progression allowing us to discover more. Two scientists who were at the foremost end of chemistry advancement during the mid 1800’s were Robert Bunsen and Gustav Kirchhoff. The two were…
