Quantum tunnelling

James Chadwick was born October 20, 1891 in Cheshire, England. He received the Nobel Peace Prize in 1935 for the discovery of the Neutron. He is the son of John Joseph Chadwick and Anne Mary Knowles. Not much is known about his early childhood, except that he came from a poor family at who struggled to get by at many times. Ever since his early childhood he was very smart, at the age of 11 he won the chance to go to the adored Manchester Grammar School. He was sadly unable to attend because his family

Stage 1 Physics investigation - Parachute Investigation The purpose of this assignment is to work out a parachute design and investigate parachute’s drop time. Parachutes are designed to fall slowly so that the person can land safely to the ground, as shown in figure 1. Parachutes are big, but not heavy and have a larger surface area for air resistance like traps the air from escaping out of it. This is because the air pushes the parachute back up, but the force of gravity pulls the parachute to

mainly because of his achievements in the fields of quantum electrodynamics, and other works while being a theoretical physicist. Feynman was also able to be recognized as one of the leading figures in the U.S. atomic bomb program, and received many awards during his lifetime; most famously the Nobel Prize in 1965.     One of Richard Feynman’s most notable achievements was his achievements in remaking modern day quantum electrodynamics. Quantum electrodynamics is the theory of interaction between

Otto Robert Frisch was born in Vienna, Austria on October 1st, 1904 to Justinian and Auguste Meitner Frisch. His father and mother were a painter and a concert pianist, respectively. Frisch’s aunt was Lisa Meitner, a physicist. Otto shared her love of physics and would later work with her and make an important discovery that was essential to the creation of the atomic bomb. Frisch came from a Jewish family, so when Adolf Hitler rose to power and started persecuting the Jews, it had a direct impact

Shima Mohammadi Chapter 20 CQ 20.01 “The particles in the pulse travel from one place to another”, it’s incorrect because the definition of wave is transferring energy without transferring any mass. So particles don’t travel in pulse. 20.03 “The wave continues to travel for 0.20s before stopping”. Its wrong since period is the time for one complete vibration and it doesn’t relate to the time that wave stops. “The wavelength is 0.20s”. It’s wrong, because 0.20s is the wave’s period not its wavelength

“How safe do you feel?” Ironically these were the words M said just before the attack of the cyberterrorist Silva. No longer are days of ridiculous plot lines and unrealistic events. Bond is now living in a world unstable and vulnerable to threats. This is all because of the devastating effects of the 9/11 tragedy. Society still mourning the loss of loved ones; we see this ripple effect shown in the reinvented 2011 Skyfall film. The Bond series has made a dramatic change from the 1990 Brosnan era

Teleportation and How it Will Affect the Human Body "Beam me up Scotty." You may know what movie this is from. Star Trek right? But teleportation isn't all of the Star Trek fun you think it is. Teleportation does not exist yet, but when (or if) it ever does, it can actually be pretty scary. What is teleportation? How will it work? What are the theories about it? How can it be harmful? To find out, you have some reading to do. Teleportation is the theoretical transfer of matter or energy from one

Light being a particle or wave has provoked controversy amongst many scientists across the world. Back then some scientist argued that light was a particle and not a wave. Others, however, believed that light was a wave and thought it had no properties of a particle. Einstein decided to take matters into his own hands and find out what light was with the help of Max Planck. Light, to begin with, is electromagnetic radiation that is extremely wide or small but enough for it to be visible for us to

radiation was found in 1974. This showed that radiation can escape black holes. Many people believed nothing could escape until Hawkings proved this. Stephen Hawkings helped contribute to the findings of cosmic inflation. He was the first to calculate quantum fluctuations, which were created with this theory. They showed how they might help the spread of galaxies within our universe. In 1993, Hawking published the Hartle-Hawking state along with James Hartle. They predicted that time did not exist until

Stephen Hawking was born on January 8th, 1942, in Oxford, England. It is said that in his early years he had a passion for the sky and the sciences. In his academic life he was not an exceptional student. Stephen Hawking desired to study mathematics, but Oxford did not offer a degree in that field. He decided to study physics, but more specifically, cosmology. Hawking did not put much time into his studies. In 1962 Hawking graduated with honors in natural science and went to attend Trinity Hall at
