Manchester and the Birth of the Industrial Revolution
What was so exciting about Manchester? Disraeli with his acute political and historical instinct understood that Manchester had done something unique and revolutionary. Only he was wrong to call it science. What Manchester had done was to invent the Industrial Revolution, a new style of life and work which began in that little country town about two hundred years ago and inexorably grew and spread out from there until it had turned the whole world upside down. Disraeli was the first politicia...Folksonomies: academia revolution

The Need for Diversity and Empathy in Science and Religion
The diversity of science also finds a parallel in the diversity of religion. Once, when I was a child, walking with my mother through the English cathedral town of Winchester, I asked her: "Why are there so many different churches?" My mother gave me a wise answer: "Because God likes it that way. If he had wanted us all to worship him in one church, he would not have made so many different kinds of people." That was an answer invented on the spur of the moment to satisfy the curiosity of a fi... 1 notes

Odd Sympathy
Laid up in bed during a brief illness and idly watching two clocks mounted in one case, Huygens noticed something strange: No matter how the pendulums started out, eventually they always ended up swinging in exactly opposite directions. Huygens wondered whether this odd sympathy might solve the longitude problem. Perhaps, he thought, two such clocks could regulate each other. If one got dirty, for instance, and started running slow, the influence of the other clock would lessen this effect. I... 1 notes
notesMathematician Christiaan Huygens, inventor of the pendulum clock found that two clocks on the same wall will invariably come into counter-synchronization with one another. This is because of thermodynamics and their connection via the support beam in the wall.

Bayes and Richard Price on Predictions
Bayes’s much more famous work, “An Essay toward Solving a Problem in the Doctrine of Chances,”24 was not published until after his death, when it was brought to the Royal Society’s attention in 1763 by a friend of his named Richard Price. It concerned how we formulate probabilistic beliefs about the world when we encounter new data.
Price, in framing Bayes’s essay, gives the example of a person who emerges into the world (perhaps he is Adam, or perhaps he came from Plato’s cave) ...Folksonomies: statistics predictions

Davy Connects Science to Hope
But Davy wished to make even bigger, philosophical claims for the scientific spirit and imagination. Drawing on his previous exchanges with Coleridge about the ‘hopeful’ nature of scientific progress, he put before his audience a vision of human civilisation itself, brought into being by the scientific drive to enquire and create. Science had woken and energised mankind from his primal ignorance and ‘slumber’. This was in effect Davy’s version of the Prometheus myth: ‘Man, in what...
2 Science is Hope according to the former President of the Royal Society.

Davy Refused to Patent His Safety Lamp
John Buddle, now entirely won over by Davy, was also concerned about a reward. By August there were 144 safety lamps ‘in daily use’ at Walls End, and they were rapidly spreading to all the other collieries in the North-East.91 Buddle urged Davy to take out a patent, pointing out that he could not only make his fortune but control the quality of the lamps issued to miners. Davy consistently refused, although he knew his colleague William Wollaston had made a fortune with a patent on proces... 1 notes

Davy VS Gay-Lussac in the Race to Discover Iodine
He was warmly received by Cuvier, Ampère and Berthollet, but got into an awkward priority dispute with the gifted young chemist Joseph Gay-Lussac. Gay-Lussac, Davy’s exact contemporary, had made a popular name in France with his intrepid ballooning exploits, and had been hard on Davy’s heels with potassium and sodium experiments. Both were now given by the Académie des Sciences a newly isolated substance to analyse: a strange violet crystal recently found as a byproduct of gunpowder man... 1 notes
notesStill disputed as to who won the race.

Herschel's Heterodox Opinions
Laplace’s cool confidence in avowing atheistical sentiments was legendary. The story was told that after Napoleon had inspected a copy of Laplace’s Systéme du Monde, he challenged the astronomer about his beliefs. ‘Monsieur Laplace! Newton has frequently spoken of God in his book. I have already gone over yours, and I have not found His name mentioned a single time.’ To this Laplace made the magnificent and disdainful reply: ‘Citizen First Consul, I have no need of that hypothesis.... 1 notes
