Elementary particle

Introduction Around 90% of the universe is currently undetectable.[1] Allowing oneself to then believe that all the experiments and missions carried out for space exploration and countless images portraying the beauties of the world beyond the sky has only shown around 10% of the contents of the universe is unfathomable. So what mysteries lurk in the void of our universe? Any Physicist, or fellow inquisitive mind reading this, will immediately have two distinct phrases come to mind: Dark matter…

One observes an electron, and it is a particle, like a little bullet, obeying the laws of classical physics; yet as soon as you are not looking it behaves like a wave. Scientists have discovered that if they “watch” a subatomic particle as it passes through slits in a barrier, it behaves like a particle, like an object; it passes through one or the other slits. But if the scientists do not observe the particle then it observes the behavior of a wave. The two-slit experiment…

A proton is a positively charged elementary particle. The protons are accelerated using a cyclotron and then focussed into a beam and directed into the gantry using magnetic fields (REFERENCE). The proton beam can then be guided to the target area in the patient where the individual protons will…

In elementary school, my science club built a 5-foot-long DNA double helix model. My excitement for genetics and collaboration never ceased. At Columbia, I hope to "build" a strong academic base in biology. Whether I go into pharmacy or pharmacology, biology will be an integral part of my studies. Observing a man who was shot five times and another who had severe brain trauma from a motorcycle accident affected me. I encountered these patients while on rounds at the LSU Intensive Care Unit. I…

defined as moles (mol) solute per kilograms (kg) solvent (Oleson, Andrew and Daly, Terik). Colligative properties are properties of solutions that depend on the number of particles in a volume of solution and not on the mass of the particles (Helmenstine). A colligative property is a property that depends on how many solute particles are in the solvent, not the kind of solute (Oleson, Andrew and Daly, Terik). In chemistry, the colligative properties are factors that determine how the properties…

13. What is the process resulting in antigen and antibody moving toward each other? One dimensional diffusion Enzyme-Linked Immunosorbent Assay 14. In the “sandwich” analogy of the direct ELISA, what is the “bread”? Antibodies What is the filling? Antigens 15. Describe some advantages of using the ELISA technique to process a large number of samples. The advantage of Sandwich ELISA is that the sample does not have to be purified before analysis,…

applied to particles as small as atoms which is another reason why dark energy is not fully…

Gallium will melt when held in the palm of the hand and on so doing it also shrinks in volume. Gallium has been used to detect neutrinos (these are elementary particle with zero charge and virtually zero mass) emitted by the sun. Gallium is a moderately abundant element in the Earth's crust. Its abundance has been estimated to be about 5 parts per million. It is found primarily in combination with zinc and…

A chance observation and acknowledgement of an error produced the theory of dark matter, a theory that challenged everything that was known about the universe. Hairy dark matter is an elementary solution to the issue of detecting dark matter. The information that can be gathered from hairy dark matter would be a fingerprint of the layers of cosmic bodies, and could even be used to map the oceans on Earth. Hairy dark matter is the universe’s…

Shirley Ann Jackson Shirley Ann Jackson was born August 5, 1946 Washington, D.C. She developed interest in science and mathematics during her childhood and conducted experiments and studies. Such as the eating habits of honeybees. Her parents were Beatrice and George Jackson. Her father encouraged her interest in science by assisting her with projects for her school. Her mother, would read her the biography of Benjamin Banneker, an African American scientist and mathematician who helped build…
