Who Discovered it?
When and Where was it Discovered?
On August 18th, 1868, a French astronomer named Pierre Janssen was looking at a solar eclipse when he saw a big bright yellow line. At first, he thought that the line was sodium.
Then, in October, 1868, an astronomer from England named Norman Lockyer saw the same yellow line and he also thought it was sodium. According to Lockyer, sodium already has two lines, D1 and D2, so he named this new line as D3 Fraunhofer line. Later on, he decided that the line wasn't sodium and that it wasn't any known object from earth either.
Both Lockyer and a chemist from England named Edward Frankland, named the unidentified object as helios. Helios is the synonym for the Sun in Greek. As he used the D3 spectral line and first traced ...
Genetic Engineering, history and future Altering the Face of Science. Science is a creature that continues to evolve at a much higher rate than the beings that gave it birth. The transformation time from tree-shrew, to ape, to human far exceeds the time from analytical engine, to calculator, to computer. But science, in the past, has always remain...
The good effects of an avalanche An avalanche clears an area of trees and other obstacles. In the warmer months, land that experienced an avalanche in the previous winter will be clear, which creates a path up the mountain that offers easier traveling for both humans and animals. This helps animals cover ground more easily while hunting and offers...
The theory that black holes have existed is not new at all. The thought of them first started in 1783 when Rev. John Michell applied Newton's theory of gravity to predict the possibility of so-called 'dark stars.' Albert Einstein's theory of relativity predicted in 1915 'Schwartzschild singularities.' In 1967, these were renamed 'black holes.'...

In the late 1800's it was discovered that papa-amino-phenol, could reduce fever, but the drug was too toxic to use. A less toxic extract called phenacetin was later found to be just as effective but also had pain-relieving properties. In 1949, it was learned that phenacetin was metabolized into an active but also less toxic drug, . Since then, ha...
In this report I will give a history on the development of . I will cover some of the most important dates in the development of atomic theory. An atom was first thought of by the Ancient Greeks who believed that matter was made of smaller particles called elements. The name they gave to these particles was the atom. In 1776 the man known as "T...

"It discloses secrets; ratifies and confirms our hopes; thrusts the coward forth to battle; eases the anxious mind of its burthen; instructs in arts. Whom has not a cheerful glass made eloquent!

The engineering of deoxyribonucleic acid (DNA) is entirely new, yet genetics, as a field of science, has fascinated mankind for over 2,000 years. Man has always tried to bend nature around his will through selective breeding and other forms of practical genetics. Today, scientists have a greater understanding of genetics and its role in living orga...
Of all the terms coined by scientists which have entered popular vocabulary, 'clone' has become one of the more emotive.
