62. The Hilltop Writers By W.R. (Bob) Trotter Jane (née TIMMS) 18761947; Tyndall John FRS 1820-1893; WALES Hubert(pseudonym of William PIGGOTT) 1870-1943; WARD Mrs Mary Augusta http://www.johnowensmith.co.uk/hilltop.htm

The Hilltop Writers A Victorian Colony among the Surrey Hills Literary Heritage around Haslemere by W.R. (Bob) Trotter New illustrated edition published in 2003 Index to the 65 names featured in the book Charles Darwin’s cousin dies in Grayshott Bertrand Russell falls in love in Fernhurst Disgraced London society hostess starts a home for deprived children in Hindhead Astronomical observatory built underneath the Devil’s Jumps near Churt Review Mr Trotter discovered in the archives of Haslemere Museum a remarkable collection of notes and newspaper cuttings left by local journalist William Sillick, who died in 1955. It made him realise what an astounding flurry of important literary activity there had been in the neighbourhood of Haslemere during the fifty years or more following the arrival of the railway in 1859, and from this the book was conceived. The book is organised into four main sections: a brief local chronology from 1859 through to the start of the First World War; a short discussion of the politics and other issues in vogue during the period; biographical notes on each of the writers; and an appendix of references and other more general notes, including a superb 20-page index. It is a pleasure to read. Bob Trotter has not only encapsulated the essentials of these people’s lives in his pages, but also given us the benefit of his medical training to add his own fascinating personal comments. And in these days of generally slap-dash editing, it is nice for once to find a book where so much care and attention has obviously been taken in checking presentation and content before publication.

64. Tyndall's Water-Boiling Apparatus John Tyndall (18201893) was a native of Ireland who is best known for his seriesof lectures at the Royal Institution of London, and the books which he wrote http://physics.kenyon.edu/EarlyApparatus/Thermodynamics/Tyndalls_Water-Boiling_A

Tyndall's Water-Boiling Apparatus This is a Mechanical Equivalent of Heat demonstration. A [missing] belt connects the two pulleys, and allows the smaller pulley to be driven at a high rotation rate as the hand-crank is turned. Projecting upward from the smaller pulley is a thin-walled brass pipe, partly filled with water and closed with a cork. Two pieces of oak, hinged together, surround the pipe and are held in place by the hand of the demonstrator. The work done in turning the crank against the frictional torque serves to heat the water to boiling, whereupon the cork pops out. John Tyndall (1820-1893) was a native of Ireland who is best known for his series of lectures at the Royal Institution of London, and the books which he wrote on optics, electricity and heat. This remnant of the demonstration is at the University of Texas at Austin.It is from the earlier part of the twentieth century and is unmarked. The 1928 Welch catalogue describes a similar piece of apparatus as COUNT RUMFORD'S EXPERIMENT, Tyndall's Friction Cylinder

65. Tyndall's Apparatus When the source of heat is removed, the bar cools and contracts, and eventually therod is sheared. Tyndall is John Tyndall (18201893), the Irish researcher http://physics.kenyon.edu/EarlyApparatus/Mechanics/Tyndalls_Apparatus/Tyndalls_A

Tyndall's Apparatus The tag on this apparatus at the University of Vermont says that it is Tyndall's Apparatus, and the apparatus was designed to show the enormous force exerted by a bar of iron as it is cooled. Hrvoje Mesic of the University of Zagreb, who uses a similar piece of apparatus made in the early part of the 20th century in lecture demonstrations, described to me the operation of the apparatus. A gas burner composed of a long pipe with apertures in it, is slid under the square iron bar, and causes it to expand. A rod of metal about 5 mm in diameter holds the bar in place on the left-hand side and the screw on the right-hand side is tightened up as the bar expands. When the source of heat is removed, the bar cools and contracts, and eventually the rod is sheared. "Tyndall" is John Tyndall (1820-1893), the Irish researcher, writer and lecturer who was the Professor of Natural Philosophy at the Royal Institution in London and later the director of the Royal Institution. His books on heat, optics and sound were widely read and admired. This apparatus may be a consequence of his studies of the effects of pressure on slate dating from the middle 1850s.

Related pages: Black sky? Earth shadow Mars Other Why is the sky blue, and sunsets golden? The color of our sky is caused by the interplay of blue-light-scattering by air molecules, and white-light-scattering by water drops and dust... Blue wavelengths are generally scattered down toward the earth. This makes the sky appear blue wherever it is daytime (and the sun is high in the sky). At sunset, however, the opposite occurs. Glowing beam of the "bat signal," as imagined in a 1950's comic book cover. In reality, rays of light are invisible in the vacuum of space. In earth's atmosphere, however, the rays of our sun are faintly visible, spanning across our planet... appearing as a blue sky. Leonardo da Vinci had observed that a very fine water spray produced light scattering, but for many centuries only confusing and misleading ideas abounded. The English experimentalist John Tyndall (1820-1893) demonstrated that the scattering from particles small compared to the wavelength of light depends on the wavelength, with blue being much more strongly scattered than red. Why are sunsets red?

77. EO Library: John Tyndall John Tyndall was a man of science—draftsman, surveyor, physics professor, mathematician,geologist, atmospheric scientist, public lecturer, and mountaineer. http://earthobservatory.nasa.gov/Library/Giants/Tyndall/

In January 1859, Tyndall began studying the radiative properties of various gases. Part of his experimentation included the construction of the first ratio spectrophotometer, which he used to measure the absorptive powers of gases such as water vapor, "carbonic acid" (now known as carbon dioxide), ozone, and hydrocarbons. Among his most important discoveries were the vast differences in the abilities of "perfectly colorless and invisible gases and vapors" to absorb and transmit radiant heat. He noted that oxygen, nitrogen, and hydrogen are almost transparent to radiant heat while other gases are quite opaque. Tyndall's experiments also showed that molecules of water vapor, carbon dioxide, and ozone are the best absorbers of heat radiation, and that even in small quantities, these gases absorb much more strongly than the atmosphere itself. He concluded that among the constituents of the atmosphere, water vapor is the strongest absorber of radiant heat and is therefore the most important gas controlling Earth's surface temperature. He said, without water vapor, the Earth's surface would be "held fast in the iron grip of frost." He later speculated on how fluctuations in water vapor and carbon dioxide could be related to climate change. The above graphs show the percentage of radiation that gases found in the Earth's atmosphere absorb. Methane (CH

John Tyndall (1820 - 1893) John Tyndall was born into a small landowning family in Country Carlow in Ireland. Although relatively poor, his father ensured his son received a good elementary education. A gifted child, he would walk home with his tutor, working on Euclid's geometrical problems in the snow. He began work as a draughtsman with the Ordnance Survey in 1839, and then travelled to the University at Marburg in Germany to study chemistry and physics. He received his PhD in two years, published his first paper a year later and became a fellow of the Royal Society a year after that. In 1853 he started working alongside Michael Faraday at the Royal Institution where he continued his research, succeeding him there as superintendent in 1867. Over the previous decade he had been researching heat transfer in gases and vapours, with interesting results. Taking some very pure, highly filtered water, he saw that a visible beam of light completely disappeared when it went through the pure water. He repeated the experiment with filtered air and achieved the same result. He had discovered that light only became visible after bouncing off air particles. He experimented further by changing the size of the particles and found that different sized particles scattered light in different ways. In the 1660s Newton had demonstrated that visible light coming from the sun was made up of different colours. Tyndall discovered that light at the blue and violet end of the spectrum was scattered by minute particles and light at the red end was scattered by bigger particles. Because the atmosphere contains smaller particles, scattering the blue light, the sky appears blue. He went to show that 'optically pure' air contains no bugs or germs by preparing various concoctions of dead fish and meat and then letting them putrefy. The same concoctions in pure air did not do this.
