When Google chief financial officer Patrick Pichette said the tech giant might bring10 gigabits per second internet connections to American homes, it seemed like science fiction. That’s about 1,000 times faster than today’s home connections. But for NASA, it’s downright slow. While the rest of us send data across the public internet, the space agency uses a shadow network called ESnet, short for Energy Science Network, a set of private pipes that has demonstrated cross-country data transfers of 91

Lab Assignment 4: Types of Force Instructor’s Overview In many physics problems involving Newton’s laws of motion, you’ll see statements like, “assume a frictionless surface” or “neglecting air resistance…” In this lab we will be exploring both friction and air resistance, two resistive forces that are critical in the design of real-world products and systems. Understanding the effects of these types of forces is essential in the design of such things as aircraft, automobiles, braking systems

Physics Homework, Unit 9 Deborah Williams 08/13/2014 Pg. 268-269-1. What is the source of wave motion? Answer: A wiggle in space and time. 2. If we double the frequency of a vibrating object, what happens to its period? Answer: Frequency and period are the inverse of each other. Frequency = 1/period or Period = 1/frequency 36. A railroad locomotive is at rest with its whistle shrieking, and then it starts moving toward you. a. Does the frequency that you hear increase, decrease

Physics h/wk. The Majestic Sombrero Galaxy The Sombrero Galaxy (also known as M104 or NGC 4594 ) is an unbarred spiral galaxy in the constellation Virgo located 28 million light years from earth. It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its inclined disk. The dark dust lane and the bulge give this galaxy the appearance of a sombrero. The galaxy has an apparent magnitude of +9.0, making it easily visible with amateur telescopes. The large bulge

How has the model of the structure of the atom changed over time? The idea of an atom was first conceived by the ancient philosophers of Greece. In the fifth century BC, Leucippus and his student Democritus suggested that there were small indivisible particles, which he called atoms – from the Greek atomos meaning ‘uncuttable’. This idea of atoms has been built on by many other scientists over hundreds of years. These scientists have drawn conclusions from a variety of different experiments.

Collider (LHC) are more than 99 percent certain they've discovered the Higgs boson, aka the God particle—or at the least a brand-new particle exactly where they expected the Higgs to be. The long-sought particle may complete the standard model of physics by explaining why objects in our universe have mass—and in so doing, why galaxies, planets, and even humans have any right to exist. "We have a discovery," Heuer said at the seminar. "We have observed a new particle consistent with a Higgs boson

with early experiments at Cern in Europe and Fermilab in the US. Does finding the Higgs boson mark the end of the search? It's just the end of the beginning. Confirming the existence of the Higgs would only be the start of a new era of particle physics as scientists focus on understanding how it works and look for unexpected phenomena. How do you find a Higgs boson? To find the particle and characterise it, scientists must first try to create it by smashing beams of protons together inside the

Medical Imaging Physics- W. R. Hendee Chapter 7- Interaction of X and γ Rays in the Body A Summary submitted by Miles Que I. Introduction The dominant interaction of X and γ rays in the body depend of three main factors: electron density, effective atomic number and the photon energy. All of which, cause different reactions in the body which is divided into four regions: fat, muscle, air- filled cavities and bones. II. ƒ Factor As discussed in the previous chapters, an exposure of 1 Coulomb/
