God Particle Aparajita Srivastava The "God particle" is the nickname of a subatomic particle called the Higgs boson. In layman’s terms‚ different subatomic particles are responsible for giving matter different properties. One of the most mysterious and important properties is mass. Some particles‚ like protons and neutrons‚ have mass. Others‚ like photons‚ do not. The Higgs boson‚ or “God particle‚” is believed to be the particle

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

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

engineering and technology conducted at nanoscale. Two of the main applications of nanotechnology include material science and biomedicine. We have achieved great strides in applying nanotechnology to material science that is well justified by the decreasing size of electronics available in market. However we haven’t made a mark in biomedicine yet. In 1971‚ US President Richard Nixon and Congress declared war on cancer. Since then a large amount of research has been carried out towards diagnosis and treatment

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

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

several cyanine dyes and then interpret them to a simple model of the electronic structure of the π system: the Particle in a Box. Theoretical Model “Particle in a Box” In the Particle in a Box model‚ all potential energy interactions are assumed to be zero (constant) along the chain except at ends of the chain where the potential energy abruptly goes to +. If a particle moving freely along the length of the box the energy can be calculated as :

It is assumed that the π electrons are free to move and ignoring the electro static repulsion among the π electrons themselves. The theoretical model applied in this experiment is the particle in the box. The model states that a single particle moves free
