Magnetic particle inspection (MPI) - Is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferroelectric materials such as iron‚ nickel‚ cobalt‚ and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs

Karla Alvarez Chemistry Period One Subatomic Particle The electron is extremely small compared to all the other parts of the atom. It is negatively charged. The negative charge balances out the positive charge of the protons in the atom. Electrons are found in the electron cloud that surrounds the nucleus of an atom. The clouds are generally organized into shells. Electrons move at a quick pace‚ so you never really know where they are specifically. But after years of doing experiments‚ scientists

The Higgs boson is popularly referred to as "the God particle‚" perhaps because of its role in giving other particles their mass. However‚ it’s not the boson itself that gives mass. Back in 1964‚ Peter Higgs proposed a theory that described a universal field (similar to an electric or a magnetic field) that particles interacted with. Don Lincoln‚ a physicist at Fermilab in Illinois‚ explained to ABC News‚ "It’s the Higgs field that gives particles their mass." The boson itself is more like evidence

Particle Fever directed by Mark Levinson‚ is a documentary about a scientific experiment which took almost twenty years to complete. Although it involved ten thousand engineers from one hundred different countries‚ it depicts the experiences of just a few scientists. In the film‚ each scientist describes the journey that they went through in order to complete the complicated project. Costing up to ten billion dollars‚ it was one of the world’s most expensive science experiments. In addition‚ it caused

In the film‚ Particle Fever‚ it primarily focuses on an experiment but there are time where art is incorporated throughout the film. While Art and Science are too different things‚ they are more alike than they appear‚ they both are human attempts to represent and exhibit more about the world. In Particle fever‚ it fills in the story of Higgs bason’s great finding‚ and masterly intertwined through the story‚ are parallels between science and art. Science and art‚ the methods of the two have different

use a unit that is a certain number of particles. This unit is known as the mole. A mole is the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. That number of particles is Avogadro’s Number which is about 6.02 x 1023 ‚ representative particles. That is an SI unit for measuring the

Diffusion‚ Osmosis‚ Active Transport There are two ways in which substances can enter or leave a cell: 1) Passive a) Simple Diffusion b) Facilitated Diffusion c) Osmosis (water only) 2) Active a) Molecules b) Particles Diffusion Diffusion is the net passive movement of particles (atoms‚ ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It continues until the concentration of substances is uniform throughout. Some major examples of diffusion

contributed to theories involving light. Of these‚ the wave-particle duality is arguably the most strange and noteworthy concept in the field. Throughout history‚ some physicists have argued that light behaves as a wave‚ such as Christiaan Huygens and others‚ such as Isaac Newton have proposed that light consists of particles (Wave-Particle Duality‚ March 2010). Today‚ as stated in the wave-particle duality‚ light is said to exhibit wave-like and particle-like properties. And still today‚ physicists are troubled
