O.K., this site about Victoria microscope slides has to be one of the coolest things I’ve seen in a while. Lots to peruse, but why not just start with how beautiful the mounting looks.
“By the later 1800s, with the advent of an expanding middleclass and the burgeoning popular interest in the Natural Sciences, it was not unusual for households to have a well used microscope and a little “cabinet of curiosities”. Some, as well as purchasing commercially mounted examples, found pleasure in collecting specimens and making their own slides. Many people of the times could give the common and Latin names, and an account of the habits, for most of the plants, insects, and other living creatures both small and large in the vicinity of their town and countryside. Holiday excursions to the seashore became a popular pastime, being seen as wonderful opportunity for collecting unusual specimens for study. Public lectures, classes and demonstrations were held, and numerous societies and clubs of interested “amateur naturalists” met regularly. During the heyday of the Victorian period, the microscope and it’s attendant collection of mounted objects were not viewed as just a means to an education, or scientific tools for the laboratory, but as an interesting, wondrous, and delightful entertainment.”

Kate is awesome as always.
Tesla was celibate and never married, claiming that his chastity was very helpful to his scientific abilities. However, towards the end of his life, he told a reporter, “Sometimes I feel that by not marrying, I made too great a sacrifice to my work….” There have been numerous accounts of women vying for Tesla’s affection, even some madly in love with him. Tesla, though polite and soft-spoken, behaved ambivalently towards these women in the romantic sense. (Wikipedia)
“The work begins the day before launch, when he [Dan Winters] positions up to nine cameras as little as 700 ft. (213 m) away from the pad. Each camera is manually focused and set for the particular shot it is meant to capture, and the wheels of the lens are then taped into position so that they can’t be shaken out of focus when the engines are lit. Electronic triggers—of Winters’ own devising—that do react to the vibrations are attached to the cameras so that the shutter will start snapping the instant ignition occurs.
To prevent the cameras from tipping over on their tripods, Winters drills anchoring posts deep into the soil and attaches the tripods to them with the same tie-down straps truckers use to secure their loads. He also braces each leg of the tripod with 50-lb. (23 kg) sandbags to minimize vibration. Waterproof tarps protect the whole assembly until launch day, when they are removed and the cameras are armed. Throughout the launch, they fire at up to five frames per second. Only after the vehicle has vanished into the sky and the pad crew has inspected the area for brushfires, toxic residue and other dangers, are the photographers allowed to recover their equipment.

“The physicist Victor F. Weisskopf — the colorful director in the early 1960s of CERN, the European Organization for Nuclear Research, which operates the collider — once described large particle accelerators as the gothic cathedrals of our time. Like those beautiful remnants of antiquity, accelerators require the cutting edge of technology, they take decades or more to build, and they require the concerted efforts of thousands of craftsmen and women. At CERN, each of the mammoth detectors used to study collisions requires the work of thousands of physicists, from scores of countries, speaking several dozen languages.”

“Vladimir Markovnikov,a chemist and political progressive, was outmaneuvered by the crafty and conservative Aleksandr Zaitsev. Both men would go on to fame as discoverers of signiﬁcant trends in chemical reactivity and organic chemistry students today still learn “Zaitsev’s Rule” and “Markovnikov’s Rule.”
“So, organic chemistry has come a long way from its early days. It might have reached its peak,in a certain sense, around 1972, when Robert Woodward of Harvard and Albert Eschenmoser of the Swiss Institute of Technology synthesized the very complex molecule we know as vitamin B-12. Ever since, it has been widely accepted that organic chemists can make pretty much any molecule that occurs in nature. That is really something!”

“This image from Ernst Haeckel’s 1874 The Evolution of Man shows comparisons between cross-sections of different animals and their embryos at different stages of development. For Haeckel the development of an embryo retraced the evolutionary history of the animal. The different colors represent the four types of tissues out of which all the organs formed. Ernst Haeckel.

“Nott, Types of Mankind
Here American physician J. C. Nott attempted to illustrate geologist Louis Agassiz’s theory, which was that each region of the world was populated by separately created sets of species, both animal and human. Such ideas about human species at the time were often influenced by western racial prejudices, as the idea of multiple, separately created races could be used to justify slavery and other forms of subjugation. Darwin disagreed, firmly maintaining that all humans were descended from the same human ancestor. Josiah Clark Nott (1804–1873). Types of Mankind…. Philadelphia: Lippincott and Grambo, 1854.” – link
