Lodestone
An example from demonline (UCT Physics Department’s website with descriptions of educational demonstrations). Its description reads: ‘A lodestone is suspended by a string. Show that it rotates on bringing a magnet near it. Dip it into iron filings and show that it picks them up.’ -
About Ed Ricketts
"Just about dusk one day in April 1948 Ed Ricketts stopped work in the laboratory in Cannery Row. He covered his instruments and put away his papers and filing cards. He rolled down the sleeves of his wool shirt and put on the brown coat which was slightly small for him and frayed at the elbows. He wanted a steak for dinner and he knew just the market in New Monterey where he could get a fine one, well hung and tender. He went out into the street that is officially named Ocean View Avenue and is known as Cannery Row. His old car stood at the gutter, a beat-up sedan. The car was tricky and hard to start. He needed a new one but could not afford it at the expense of other things. Ed tinkered away at the primer until the ancient rusty motor coughed and broke into a bronchial chatter which indicated that it was running. Ed meshed the jagged gears and moved away up the street. He turned up the hill where the road crosses the Southern Pacific Railways track. It was almost dark, or rather that kind of mixed light and dark which makes it very difficult to see. Just before the crossing the road takes a sharp climb. Ed shifted to second gear, the noisiest gear, to get up the hill. The sound of his motor and gears blotted out every other sound. A corrugated iron warehouse was on his left, obscuring any sight of the right of way. The Del Monte Express, the evening train from San Francisco, slipped around from behind the warehouse and crashed into the old car. The cow-catcher buckled in the side of the automobile and pushed and ground and mangled it a hundred yards up the track before the train stopped" (Steinbeck 1951: 279). After Ricketts' death in 1948, Steinbeck dropped the species catalogue from the earlier 'The Sea of Cortez' and republished it with a eulogy to his friend added as an afterword. -
Deductions from smooth rocks
Extract from Bettie Higgs's reading of rocks in 'Visual Practices Across the University'. Most of the rocks in this photograph are about 360 million years old, so the grains that comprise them are substantially older. The grains came originally from a mountain range, as large as the Himalayas, whose roots can still be seen in counties Mayo and Donegal, in the northwest of Ireland. The grains were carried south by rivers and deposited in this area; the smallest grains were carried all the way to the ocean, which was far south of Cork at the time, in what is now the Atlantic Ocean south of Ireland. (There was very little rainfall at the time: the portion of land that is now Cork was 10° south of the Equator. This can be deduced from the properties of the iron in the rock.) The water in which the grains were transported was oxygenated, and the iron precipitated out as iron oxide (haematite), which cemented the grains and which accounts for the red color (Elkins 2007: 74 - 78). -
Breath of a Physicist
William Blake, 1794, Ancient of Days Inscription: "In his hand, he took the Golden Compasses, prepared in Gods Eternal stone, to circumscribe This Universe, and all created things One foot he center'd, and the other turn'd Round through the vast profundity obscure, And said, thus farr extend, thus far thy bounds, This be thy just circumference, O World" "In the process of realising this work, [Cornelia] Parker facilitated the collaboration of scientists from the physics department with those from its art gallery. She also drew attention to the scientific qualities of the artwork and, through the performative act of igniting a firework display, the symbolism of scientific discovery" (Liebenberg 2021: 31). -
Graphene
"Parker formulated 'Breath of a physicist' while engaging with the academic communities of the University of Manchester in 2015. She worked closely with the scientists of the institution, most notably Kostya Novoselov, who, with Andre Geim, was awarded the Nobel Prize for the discovery of graphene – the world’s thinnest and strongest material. After being inspired by the discovery of a graphite drawing by William Blake ('The ancient of days') in the university’s art collection, Parker facilitated a collaboration between the gallery staff and Novoselov in which he sourced microscopic samples of graphite from the drawing, as well as graphite from drawings by Turner, Constable and Picasso and from a pencil-written letter by Sir Ernest Rutherford (who split the atom in Manchester), which all formed part of the university’s collections. Novoselov produced graphene from these samples, which Parker then used to make her own artwork and a ‘Blake-graphene sensor’, which was activated by the breath of a physicist (Novoselov) and set off a firework display, returning iron meteorite into the Manchester sky on the opening night" (Liebenberg 2021: 31). -
Blaud Pills
"The most useful preparation of iron for enriching the blood in anaemia. One, gradually increased, if necessary, to four for a dose, after meals, twice or thrice daily. 'Tabloid' Blaud Pill is also issued in combination with aloin, with arsenic and strycchine, with cascara sagrada, etc. These combinations are of value when alternative and aperients agents, etc. are required in addition to Blaud Pill" (BWC 1925:120).
