...elements, with all their complexities, require a chart whose rows and columns reflect their properties and how they interact with one another. In the 19th century, several scientists worked on developing a periodic table that arranged the elements according to their atomic weight. It is Russian chemistry professor Dmitri Mendeleev, however, who is credited with developing the first real table in 1869. He organized the 63 then known elements into groups with similar properties and left some spaces blank for those whose existence he could not yet prove. In 1913 physicist Henry Moseley's experiments showed definitively that the order...

Some 40 miles east of Tripoli, a complex of white stone buildings sparkles in the sunlight. Beyond the main entrance a courtyard opens onto a verdant Mediterranean garden. One of the surrounding walls is decorated with a brightly colored, stylized representation of Mendeleev's periodic table, the catalog of the elements. The attractive complex, however, is neither a jet- setter's hideaway nor a university campus. An inscription within the periodic table proclaims, "The Revolution Forever!" and outside the gate soldiers mount guard. Welcome to Libya's Tajura Nuclear Research Center...

...slighting of scientific greats by Nobel judges has been an issue practically since 1901, the first year the awards were made. In 1905, Zuckerman notes, a Nobel committee ruled against Russian Chemist Dimitri Mendeleev, nominated for his formulation of the periodic law and the table of elements. The committee reasoned that Mendeleev's 1869 work had already been widely accepted as a basic part of chemical knowledge. Thus, because the will of Dynamite Inventor Alfred Nobel limited Nobel Prizes to "recent" discoveries, Mendeleev did not qualify. A Nobel historian later called the Mendeleev decision a regrettable error. More recently...

...Zuckerman, the Avery and Mendeleev cases are only two of many examples of committee actions that will lead to more and more "first-class scientists who are destined not to win a Nobel Prize." In part, she notes, these omissions are inevitable, because the number of scientists worldwide has grown some 30 times, while the number of science-prize recipients each year (seldom more than six) has remained more or less constant...

Ever since man emerged into consciousness, he has been trying to descry order in the world around him, often by resorting to provocative guesswork. It was an inspired guess by Dmitri Mendeleev that helped organize the elements into the periodic table. Historical guesswork is harder to prove definitely right or wrong. Spengler, who died in 1936, remains one of the few men of modern times who have attempted to assimilate all knowledge and discern a broad design. Even wrong, Spengler is more stimulating than many another historian who has never guessed...
