read archimedes' wikipedia entry

the greatest mathematician of ancient history, and one of the greatest of all time, archimedes anticipated modern calculus and analysis by applying the concept of the infinitely small and the method of exhaustion to derive and rigorously prove a range of geometrical theorems, including: the area of a circle; the surface area and volume of a sphere; area of an ellipse; the area under a parabola; the volume of a segment of a paraboloid of revolution; the volume of a segment of a hyperboloid of revolution; and the area of a spiral

 killed by a roman soldier despite orders that he should not be harmed

the last words attributed to archimedes are "do not disturb my circles"

by dividing the mass of the crown by the volume of water displaced, the density of the crown could be obtained.  this density would be lower than that of gold if cheaper and less dense materials had been added.  archimedes then took to the streets, naked, so excited by his discovery that he had forgotten to dress, crying "eureka!"

measurement of a circle..drawing a larger regular hexagon outside a circle then a smaller regular hexagon inside the circle, and progressively doubling the number of sides of each regular polygon, calculating the length of a side of each polygon at each step.  as the number of sides increases, it becomes a more accurate approximation of a circle.  after four such steps, when the polygons had 96 sides each, he was able to determine that the value of π lay between 3 1/7 (approx. 3.1429) and 3 10/71 (approx. 3.1408), consistent with its actual value of approximately 3.1416

in the sand reckoner, archimedes set out to calculate the number of grains of sand that the universe could contain..8 vigintillion, or 8 x 10^63

in the year 1500 europe knew less than archimedes who died in the year 212 bc


learned a little martian geology, iea sees a peak around 2030 for all fossil fuels, one pathogen impacted the evolution of our immune system

a mystery going back to the early years of modern astronomy, known as the mars dichotomy.  this is the contrast between the planet's southern hemisphere, which is predominantly mountainous and rugged, and the north is dominated by flat and dusty volcanic lowlands



(1) worker surveillance

when videotape technology was supplanted by digital devices that could scan multiple locations at once, the cameras first installed to protect businesses from theft shifted their insatiable gaze from the merchandise to the workers


(2) neurosexism

 when the average sizes of organs are compared by sex, there is a great difference between lungs, livers, hearts and thyroids than there is between human brainsmost brains are good enough for most things; the problem is that too many are underfed, sunk in cortisol, hemmed in by stereotypes and taken up with the demands of survival..stephen jay gould forty years ago: 'i am, somehow, less interested in the weight and convolutions of einstein's brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops'


(3) hoardiculture

 to enter his study you had to stick to narrow 'goat paths' (as they're called in the literature on hoarding) he had laid out between the columns of newspaper

in the most recent edition of the diagnostic and statistical manual of the american psychiatric association, 'hoarding disorder' was given its own entry.  dsm-5 defines it as the 'persistent difficulty discarding or parting with possessions, regardless of their actual value'


read tobacco coast: a maritime history of chesapeake bay in the colonial era by the retired director of colonial williamsburg arthur pierce middleton

 early in the seventeenth century navigators began to appreciate the advantages of the northern passage, which approximates the great circle track between england and the american coast.  it was shorter, it avoided the perilous waters off hatteras, and it lay entirely within the temperate zone, thus minimizing discomfort and disease on shipboard

the majestic but almost unnavigable susquehanna

the patapsco ferryman in 1719 received only five hundred pounds of tobacco, while in 1723 he received seven thousand pounds of tobacco

virginia, the first english colony

before the warehouse-inspection system went into effect in virginia in 1730 and maryland in 1747, hogshead cooperage continued to be characterized by carelessness, haste, and lack of uniformity

in 1682-83 the pirate william dampier and twenty of his men spent a year in virginia, where they disposed of their loot of cacao, hides, european goods, earthenware, and brandy gathered by buccaneering in the west indies.  dampier later said that virginia was a good market for loot and a good place to provision vessels, for there was a chronic shortage of european goods in the tobacco colonies and a perennial abundance of food

george washington expressed the opinion of the fishing interests when he asserted that "liverpool salt is inadequate to the saving of fish, and therefore useless in this business ... lisbon is the proper kind of salt for fish"

fore-and-aft mainsails and spankers tended to replace square sails in the interest of maneuverability, particularly on smaller vessels, such as brigs and snows, and gaff sails supplanted the lanteen mizzens


the waters of a tidal creek

in 1753 two sailors on a ship in chester river fell to quarreling.  apparently their vocabulary gave out before their anger died down, for they soon grappled with one another.  in the course of their struggle they tumbled overboard and, being unwilling to stop fighting, were drowned.  their bodies upon being recovered were buried in one grave, where, the gazette assured its readers, "they lie peaceably together"

her cargo consisted of coals, tile, beef, butter, candles, salt, bacon, nails, shoes, slippers, ribbons, earthen pots, arms, linens, shirts, copper and brass ware, and "chirurgical medicines"

the peculiar property of the chesapeake tidewater - the land's extraordinary accessibility to sea-borne traffic - that facilitated the rapid development of the two colonies and made possible the adoption of tobacco as a staple, had an adverse effect in discouraging the growth of towns and thereby depriving the tobacco colonies of the social and intellectual advantages of urban communities
