Leonardo's views of aesthetic are all important in his philosophy of life and art. The worker's thoughts on his craft are always of interest. They are doubly so when there is in them no trace of literary self-consciousness to blemish their expression. He recorded these thoughts at the instant of their birth, for a constant habit of observation and analysis had early developed with him into a second nature. His ideas were penned in the same fragmentary way as they presented themselves to his m...

The great World War was more than two-thirds over when America entered the struggle, and yet in a sense this country was in the war from its very beginning. Three great inventions controlled the character of the fighting and made it different from any other the world has ever seen. These three inventions were American. The submarine was our invention; it carried the war into the sea. The airplane was an American invention; it carried the war into the sky. We invented the machine-gun; it drove...

"The reader is requested to observe, that, though the plan of this work is entirely his own, the compiler of it does not put it forth as in any way original in respect to language or description. It is, in fact, a much better book, than if it had been what is strictly called original, (which, indeed, must have involved an utter impossibility:) for it is a selection of some of the best materials the British Museum could furnish; sometimes worked up in his own language; and sometimes—and, ind...

The audacity of my enterprise really consists in my attempting to act according to this general truth in a particular case — the case, that is, of the phenomena of animal life. I have gone on the assumption that knowledge of animal chemistry, for example, at one extreme, and of human consciousness at the other, would be simple blanks as to meaning but for the relation of the two knowledges to each other and to still more general knowledge of animal life.

Could we imagine a chimpanzee poss...

For both the mummified body and the spiritual elements which had inhabited it upon earth had to be protected from a multitude of devils and fiends, and from the powers of darkness generally. These powers of evil had hideous and terrifying shapes and forms, and their haunts were well known, for they infested the region through which the road of the dead lay when passing from this world to the Kingdom of Osiris. The "great gods" were afraid of them, and were obliged to protect themselves by the...

These additions have been incorporated in the following translation. As a basis for the analysis of our intuition of space, Professor Hilbert commences his discussion by considering three systems of things which he calls points, straight lines, and planes, and sets up a system of axioms connecting these elements in their mutual relations. The purpose of his investigations is to discuss systematically the relations of these axioms to one another and also the bearing of each upon the logical de...

The Raspberry Pi has dominated the maker scene for many years. Freely accessible I/O pins have made it one of the most popular processor boards of all time. However, the classic Raspberry Pi has no analog inputs. Direct measurement of analog values is therefore not possible. Consequently, photodiodes, NTCs, Hall sensors, etc. cannot be read directly. In addition, the pins are connected directly to the exposed contacts, i.e. without a driver or protection circuit. This can quickly destroy th...
