Nature 70: 270 (1904) A Volatile Product from Radium Harriet Brooks, McGill University, Montreal, June 28 In the course of some recent experiments on the excited radio-activity from the radium emanation, some evidence has been obtained which points to the conclusion that the emanation X of radium at one stage of the changes which it undergoes after being deposited on a solid body is slightly volatile even at ordinary temperatures. The effect which gives rise to this conclusion was first n ...

Milestones in U.S. Food and Drug Law History May 3, 1999 From the beginnings of civilization people have been concerned about the quality and safety of foods and medicines. In 1202, King John of England proclaimed the first English food law, the Assize of Bread, which prohibited adulteration of bread with such ingredients as ground peas or beans. Regulation of food in the United States dates from early colonial times. Federal controls over the drug supply began with inspection of imported dr ...

student teacher chemist biologist product A Quick Look at the History of the Periodic Table Things are different from each other, and each can be reduced to very small parts of itself. - Ancient knowledge This was noticed early by people, and Greek thinkers, about 400BC, used the words "element', and `atom' to describe the differences and smallest parts of matter. These ideas survived for 2000 years while concepts such as `Elements' of Earth, Fire, Air, and Water to explain `world s ...

We Are Stardust The Evolution of Stars What are stars? How do they affect our existence? The answers are startling. Read on for a surprising story that touches all the sciences. What is a Star? We see many points of light on a clear, dark, moonless night. Some are bright, others barely visible. If we look carefully we can make out colours. The bright star Vega (overhead in the Northern Hemisphere summer) is white; Capella (overhead in the winter) is yellow; Regulus (of Leo) ...

Fascinating facts about the invention of Book Matches by Joshua Pusey in 1889.BOOK MATCHES Humans had used controlled fire to modify their environment for thousands of centuries before means were discovered to activate fires chemically. At some time long before the beginning of recorded history, people in widely separated parts of the world learned how to spark fires at first by the friction of rubbing two sticks together, and later (and more easily) with, flint and steel.

THE MUSEUM OF THE HISTORY OF SCIENCE AT UNSW For a number of years, some members of the School of Chemistry at the University of NSW collected scientific instruments, with the idea of establishing a museum. In 1986, the Museum of the History of Science was formally established by the then Head of School (Prof. Peter Derrick), and placed under the control of Dr D S Alderdice and Dr B Craven as Co-directors. The collection now includes about seven hundred objects, dating from the early 19th C ...

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 surf ...

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 th ...

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 mus ...

Why Every English Classroom Should Have a Periodic Table? "I was going home to dinner, past a shallow pool, which was green with springing grass... when it occurred to me that I heard the dream of the toad. It rang through and filled all the air, though I had not heard it once. And I turned my companion's attention to it, but he did not appear to perceive it as a new sound in the air. Loud and prevailing as it is, most men do not notice it at all. It is to them, perchance, a sort of simm ...
