Copernicus, the astronomer, whose discoveries make him the great predecessor of Kepler and Newton, did not come from a noble family, as certain other early astronomers have done, for his father was a tradesman. Chroniclers are, however.

It would appear that the young Nicolaus, for such was his Christian name, received his education at home until such time as he was deemed sufficiently advanced to be sent to the University at Cracow. The education that he there obtained must have been in those...

MetamorphosisThe Metamorphosis (German: Die Verwandlung, also sometimes translated as The Transformation) is a novella by Franz Kafka, first published in 1915. It has been cited as one of the seminal works of fiction of the 20th century and is studied in colleges and universities across the Western world.

"Physics is all around us. It is in the electric light you turn on in the morning; the car you drive to work; your wristwatch, cell phone, CD player, radio, and that big plasma TV set you got for Christmas. It makes the stars shine every night and the sun shine every day, and it makes a baseball soar into the stands for a home run.

Physics is the science of matter, energy, space, and time. It explains ordinary matter as combinations of a dozen fundamental particles (quarks and leptons), inter...

M. Lévy-Bruhl then explains that, whilst recognising the entire coherence of Comte’s collective labours, he proposes to confine his present study to the earlier and principal work, the Philosophy, which in M. Lévy-Bruhl’s opinion is the dominant and more fruitful composition.

This he regards as the representative work of the nineteenth century, as shown by the intellectual history of the period. He points to its influence on thought in England, in Europe, and in America. It will surpris...

The Prince (Italian: Il Principe) is a political treatise by the Italian diplomat, historian and political theorist Niccolò Machiavelli. From correspondence a version appears to have been distributed in 1513, using a Latin title, De Principatibus (About Principalities). But the printed version was not published until 1532, five years after Machiavelli's death. This was done with the permission of the Medici pope Clement VII, but "long before then, in fact since the first appearance of the Pr...

IN this little book I have undertaken to lay before the reader the fruits of the labor of twenty-five years. As soon as I could understand and appreciate the splendors of the Grand Masters of painting, I had begun to form a determination to discover the technical principles, methods, and material that enabled the Masters to produce their work.

Therefore, the search for the Masters' technic became for me an all-absorbing life work to the exclusion of all else. This life work was more or less a...

I HAVE made an attempt to put forth in some kind of orderly sequence a few of the chief guiding conceptions of chemistry; endeavouring, on the one hand,

TO avoid technical details, and, on the other hand, to illustrate these conceptions by describing many common facts. I have tried to keep the attention of the reader fixed on the great generalisations of chemistry; and I have done my best to shew that these generalisations find constant application in the occurrences of everyday life.

They believe that the principles of current generation must be changed, the area of current supply be enlarged, and the appliances used by the consumer...
