Quantum chromodynamics

As a immigrant and a community college student, I enjoy changes and challenges. I wish to transfer to a four-year research university to study in a more challenging and diverse academic environment. College of Art and Science at University of Pennsylvania will be a great fit for me because of its academic rigor and liberty, premier Ivy League education, and vast research opportunities. Benjamin Franklin is my hero. I sincerely admire his versatility. His contributions on electricity is remarkable

Linus Pauling (1901-1994) A master and maker in many fields, Linus Pauling lived a very long and productive life spanning nearly the entire twentieth century. By the time he was in his twenties, he had made a name for himself as a scientist. After many significant contributions including his work on the nature of the chemical bond, he turned to chemical biology and is generally accepted as the founder of molecular biology. Later in his life he became very involved in issues of

The photo electric effect, which was first documented by Einstein in 1905, and posited that the energy of liberated electrons is linearly dependent on the frequency of incident photons. This paper investigates this relationship and measures Planck's constant ($4.36\pm 0.04\e{-21}$MeVs), and the work function of the photo diode ($-1.52\pm0.02$V). Another phenomena which is checked is the charging time of the stopping potential voltage. While there was some dependence between stopping voltage

Introduction Quantum mechanics or also known as quantum physics is a field of science which studies the behaviour of particles at sub-atomic level. This theory tells us that short-lived pairs of particles and their antiparticles are constantly being created and destroyed in an apparently empty space. In quantum mechanics the weird behaviour of electrons are not accurately explained and until now not a single theory is acceptable by the whole scientific community to postulate the phenomena. The

Various theories of quantum gravity predict the existence of a minimum length scale, which leads to the modification of the standard uncertainty principle to the Generalized Uncertainty Principle (GUP). In this paper, we study two forms of the GUP and calculate their implications on the energy of the harmonic oscillator and the Hydrogen atom more accurately than previous studies. In addition, we show how the GUP modifies the Lorentz force law and the time-energy uncertainty principle. 1. Introduction

Lab Report Module Name: Physics Fundamentals (PHYS1001) Experiment Name: Determination of Planck’s constant (h) Student P-number: P14177341 Lab Tutor : Dr Shashi Paul Date: 14/11/2014 Abstract The objective was to determine the value of Planck’s constant using LED’s. The value of Planck’s constant found in this experiment was 5.93x10-34Js, This is fairy close in comparison to the accepted value being 6.626x10-34Js. The Value of Planck’s constant was

A study on observation of photoluminiscene in Ruthenium-based dye (cis-diisothiocyanato-bis(2,2’-bipyridil-4,4’-dicarboxylic acid)ruthenium (II)) Adlina Izny binti Ahmad Advanced Material Laboratory Faculty of Industrial Sciences & Technology, Universiti Malaysia Pahang Kuantan, Malaysia Abstract Photoluminescence is light emission that form after the absorption of photons. Dye act as a light absorber. Organic dye is one type of dye, have a small band gap and use as semiconducting material.

1. Introduction. “There’s plenty of room at the bottom”; this statement by Richard Feynman in 1959 during a presentation to a meeting of the American Physical Society, is widely accepted as the spark that initiated the present ‘nano’ age1. Nano, “dwarf” in Greek, is defined as one billionth, it follows that the nanoscale is measured in nanometres, or 10-9 m. To put this in perspective; the average strand of a human hair is roughly 75,000 nm in diameter, or from the other extreme 1 nm is the length

Quantum mechanics was developed over many decades ago,Quantum mechanics is science dealing with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more particles. This type of physics beginning as a set of controversial mathematical explanations of experiments that the math of classical mechanics could not explain. It began at the turn of the

Indigos Family are characterized by their high stability that arises from inter/intramolecular hydrogen bonding. The electronic and vibronic spectra of indigos are strongly influenced by π-domains intermo-lecular interactions
