Ondiano‚ Eliza L. MSEST – 1 CENTRIFUGATION Centrifugation is a process which through rapid spinning imposes high sustained centrifugal force on suspended particles‚ or even molecules in solution‚ and causes separations of such matter on the basis of differences in densities. More-dense components of the mixture migrate away from the axis of the centrifuge‚ while less-dense components of the mixture migrate towards the axis. Effectively‚ the centrifuge substitutes a similar‚ stronger force

long-handled hooked sticks that are loosely strung with a kind of netted pouch (Farlex‚ Inc.). Behind every shot taken in a lacrosse game‚ elements of biomechanics are implemented. Biomechanics is the “sport science” field that applies the laws of mechanics (movements‚ body angles‚ joint positions‚ etc.)‚ biomedical engineering‚ and physics (gravity‚ forces‚ velocities‚ etc.) to athletic performance (What is 3D Biomechanics).

The science of matter and energy and of interactions between the two‚ grouped in traditional fields such as acoustics‚ optics‚ mechanics‚ thermodynamics‚ and electromagnetism‚ as well as in modern extensions including atomic and nuclear physics‚ cryogenics‚ solid-state physics‚ particle physics‚ and plasma physics. Physics (from Ancient Greek: φύσις physis "nature") is a natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force

In The short stories “Popular Mechanics” and “Lamb to the slaughter” a central theme that went around both stories is the topic of marital quarrels and what can result if violence is resulted too. Both stories are very similar in central idea and start to finish. In the story Popular mechanics a husband was leaving his wife and are arguing over the custody of the baby‚ but this event ends in a tragic mistake that gives the reader and the family a shock. In Lamb to the slaughter the husband Patrick

Schrödinger equation and Heisenberg uncertainty principle enable virtually everything chemistry related today. The fields of pharmaceutical chemistry and polymer science(plastics especially) would still be in their infancy if not for the work on quantum mechanics during this time. These major accomplishments were largely based on complex derivations and rarely had experiments that cost a significant sum. A common argument for the continued research in atomic and subatomic structure is the desire for a

There are two contrasting views that light either consists of particles or waves. Light is a perplexing phenomenon puzzled by Ancient Greeks and scientists for years. Even Issac Newton developed incorrect theories on light‚ when he was the inventor and genius behind physics. It has been proved that light can be both a particle and a wave. Human eyes collect light that is reflected from a source. For example‚ the light from a pencil comes from the source of light in the sun and travels to the pencil
