		The Periodic Table ^Votes:0 A BRIEF HISTORY OF THE DEVELOPMENT OF PERIODIC TABLE Although Dmitri Mendeleev is often considered the "father" of the periodic table, the work of many scientists contributed to its present form. In the Beginning A necessary prerequisite to the construction of the periodic table was the discovery of the individual elements. Although elements such as gold, silver, tin, copper, lead and mercury have been known since antiquity, the first scientific discovery of an element occurred in 1649 when Hennig Brand discovered phosphorous. During the next 200 years, a vast body of knowledge concerning the properties of elements and their compounds was acquired by chemists ( view a 1790 article on the elements). By 1869, a total of 63 elements had been discovered. As the number of known elements grew, s Read More Go to Site

		The Rotation of the Elements ^Votes:0 The Rotation of the Elements (c) 1995, John Opsopaus When thou hast made the quadrangle round, Then is all the secret found. -- George Ripley (d. 1490) The rotation of the elements is a key alchemical procedure, the principal means by which the purified essence of a substance is extracted and raised to its most sublime state. Indeed, the rotation symbolizes an important transformative process, which manifests throughout the spiritual and material worlds, but to understand it we must review the symbolic structure of the four elements. The elements have been rich symbols for at least 2500 years, for they resonate with our deepest experience of the world. Empedocles, who first identified the four elements, compared them with gods: Now hear the fourfold roots of everything: Enlivening Hera, Ha Read More Go to Site

		A Look Inside the Atom ^Votes:0 [an error occurred while processing this directive] SITE MAP Click on any image for a big picture and more information. ne hundred years ago, amidst glowing glass tubes and the hum of electricity, the British physicist J.J. Thomson was venturing into the interior of the atom. At the Cavendish Laboratory at Cambridge University, Thomson was experimenting with currents of electricity inside empty glass tubes. He was investigating a long-standing puzzle known as "cathode rays." His experiments prompted him to make a bold proposal: these mysterious rays are streams of particles much smaller than atoms, they are in fact minuscule pieces of atoms. He called these particles "corpuscles," and suggested that they might make up all of the matter in atoms. It was startling to imagine a particle resid Read More Go to Site

The effect which gives rise to this conclusion was first noticed in some observations on the rate of decay of the part of the excited activity deposited on a plate of copper immersed for a short time in dilute hydrochloric acid in which the activity from a platinum wire exposed for a time to the radium emanation ha Read More Go to Site

		Early UNL Chemistry History ^Votes:0 Hudson Henry Nicholson & Rachel Abbie Holloway Lloyd as they appeared in the 1895 student yearbook Midway into his career, University of Nebraska's first chemistry professor Hudson H. Nicholson was described as "an organizer, a man of ideas and ideals, of insistence and tact and courage" and that "by dint of his influence and vigilance and zeal...the balance of power went palpably over to the science side of the Colleges for some years to follow." Perhaps the most significant event that began his rise occurred in 1887 when he hired Rachel A. Holloway Lloyd. Nicholson had had six years of success at teaching chemistry, which caused burgeoning course enrollments.

Common chemicals may be used because standard military chemical agents may be difficult or dangerous to manufacture, access, or disperse. The Agency for Toxic Substances and Disease Registry (ATSDR) developed a 10-step procedure to analyze, mitigate, and prevent public health hazards resulting from terrorism involving industrial chemicals.

Regulation of food in the United States dates from early colonial times. Federal controls over the drug supply began with inspection of imported drugs in 1848.

		Nuclear Fission ^Votes:0 Nuclear Fission A Little History In 1932, English physicist and Nobel laureate James Chadwick discovered the neutron. A few years later, Enrico Fermi and his collaborators in Rome discovered that, if various elements are bombarded by neutrons then new radioactive elements are produced. Fermi had predicted that the neutron, being uncharged, would be a useful nuclear projectile, because it is uncharged and therefore receives no electric forces from the nucleus when it approaches the nuclear surface. In 1939, German chemists Otto Hahn and Fritz Strassman, bombarded solutions of uranium salts with neutrons. They found by chemical analysis that, afterwards, a number of new radioactive elements were present. Repeated tests convinced them that barium was produced! This puzzle was solved within a Read More Go to Site

		Origin of the Periodic Table ^Votes:0 The Origin of the Periodic Table I know what the periodic table looks like, but where did it come from? Whose idea was it to arrange the elements this way? In 1869, a Russian chemist named Dmitri Mendeleev came up with a way of organizing the elements that were known at the time. He set them out in order of atomic weight , and then grouped them into rows and columns based on their chemical and physical properties. 1869...that's way before the SchrÖdinger model , or even the Rutherford model . That's right. Mendeleev had no idea what atoms were made of or why they behaved as they did. Nevertheless, he was able to put together the periodic table almost as we know it today--except that some elements were missing, because they were unknown in 1869. Based on the gaps in his table, Mendeleev eve Read More Go to Site

In the conventional story, a stray mold spore was borne through an open window and landed on an exposed bacterial culture, Fleming later noticed a clear zone where the bacteria had been killed, he immediately recognized the thera-peutic significance of the event, and it was only a matter of time before penicillin became a miracle drug. Fleming himself often underscored the role of chance in his work. Despite the numerous honors and awards he received, he was fond of reminding others, "I did not invent penicillin. Nature did that.

He was an inveterate team player. He viewed himself less as a brilliant theoretical and laboratory scientist as he did a man who was lucky to be a member of an extraordinary team. For his work with plutonium during the Second World War, he allowed Glenn Seaborg to bask in the limelight while he shortened his life by moving to Hanford to bring to fruition the process he designed to purify plutonium on an industrial scale. After the war, in leading the Berkeley team's "discovery" of seven new actinide elements, he spread the recognition around by only taking Read More Go to Site
