Democritus

Democritus

Democritus (460 BCE 370 BCE) was an ancient Greek philosopher. He is known for his influence on modern science more than any other pre-Socratic philosopher. He was also known as the “Laughing Philosopher", for his tendency to mock fellow citizens for their follies.

Photo of a Single Atom

Photo of a Single Atom

You might need your glasses for this one. Quantum physicist David Nadlinger from the University of Oxford managed to capture an image that would have been impossible only a few years ago: a single atom suspended in an electric field viewable by the naked eye. The amazing shot titled “Single Atom in an Ion Trap” recently won the overall prize in the UK’s Engineering and Physical Sciences Research Council (EPSRC) science photo and imaging contest.

IUPAC

IUPAC

International Union of Pure and Applied Chemistry. The International Union of Pure and Applied Chemistry (IUPAC) serves to advance the worldwide aspects of the chemical sciences and to contribute to the application of chemistry in the service of Humankind. As a scientific, international, non-governmental and objective body, IUPAC can address many global issues involving the chemical sciences.

The Path to the Periodic Table

The Path to the Periodic Table

The path to the periodic table began early in the 19th century, when John Dalton united the atomic theory of matter, which had existed in various forms since antiquity, with the concept of the chemical element, which had emerged in the late 18th century with the work of Antoine-Laurent Lavoisier and his followers.

Antoine-Laurent Lavoisier

Antoine-Laurent Lavoisier

Lavoisier, a meticulous experimenter, revolutionized chemistry by establishing the law of conservation of mass, determining that combustion and respiration are caused by chemical reactions with what he named "oxygen," and helping systematize chemical nomenclature, among many other accomplishments.
