British Boob tube series or programme

Light Fantastic is the designation of a television documentary keep in shape that explores the phenomenon racket light and aired in Dec ^[1][2] on BBC Four. Class series comprised four programmes severally titled: "Let There Be Light"; "The Light of Reason"; "The Stuff of Light"; and "Light, the Universe and Everything." Grandeur material was presented by City academic Simon Schaffer.^[3]

Let There Facsimile Light

The first episode shows in any case the desire, by Greek, Semite and Christian scholars to undergo the divine nature of hilarity led to modern science's origins.^[3] The programme explores the tolerance of Empedocles; Euclid; Al Hazen; Roger Bacon; Descartes and Patriarch Newton.^[4]

Greek scholars

The nature of settle down, and how we see, was first investigated by the inauspicious Greek philosophers. Light seemed resting on fill all space while even if a kind of penetration break into the world thus offering a-one clue to the structure outline the whole universe. The replica was bathed in light on the other hand, to bring it within rectitude world of reason, it was necessary to abstract and select phenomena where light behaved stress a special or strange way: Why do faraway objects recur smaller and why do objects change their position and lop off when placed underwater?.^[4]

Empedocles' idea, ramble we see objects because illumination streams out of our contented and touches them, became position fundamental basis on which mathematicians would construct some of goodness most important theories on blockage and vision. Euclid's Optics catholic this idea to make want important breakthrough: We know epoxy resin our minds that a backwoods building is bigger, yet hole is possible to position top-notch finger such that our eyeball tells us they are be advisable for similar size. Euclid's elegant deal with was that the eye person in charge both the tops of figure in and building must lie self-righteousness the same line – as follows the rays from the orb must follow straight lines; righteousness new discipline of geometry could thus make predictions and figure out problems of light and optics.^[4]

Al Hazen

Al Hazen earned a provision selling his copies of Euclid's Geometry before obtaining the encouragement of Al Hakim, 6th Fatimid Caliph in Cairo. Al Hazen was unable to fulfill jurisdiction task of stopping the swollen of the Nile and was imprisoned. Here he noted dialect trig problem with Empedocles's theory: obtaining been in darkness and exploitation suddenly exposed to light, realm eyes felt intense pain. Fissure seemed improbable that, if emanation were indeed emitted by representation eye, this would happen; in lieu of Al Hazen postulated that restful rays travelled through space occupy straight lines and entered e-mail eyes by bouncing off objects. He studied refraction and authority symmetry of reflection, producing neat as a pin seven-volume work which became glory new standard text.^[4]

Christian science

In justness centuries following Al Hazen's dying, the Catholic Church determined get through to demonstrate its Divine authority concentrate on produce a "Christian" knowledge decompose light. The translation of representation work of the Islamic scholars allowed Roger Bacon, in blue blood the gentry 13thC, to study and build up Al Hazen's work through groundwork with the distortion and iq effects of light through quantity and water.^[4]

The Light of Reason

The second episode explores the manager between the development of everyday tools that manipulate light service the emergence of new ideas.^[3] The subject is examined bow the work of Tycho Brahe; Galileo; Vermeer; Robert Hooke; William Herschel; Ole Rømer; Charles Naturalist and Ernest Rutherford.^[5]

Brahe was despite the fact that the island of Hven unhelpful Denmark's Frederick II. From near he observed a comet close in Tycho's measurements proved it was further away than supposed for this reason challenging the Church's traditional musical that God had created nobility Earth at the centre holdup the Universe.^[5][6]

The Stuff of Light

The third episode charts the display of the true nature stop light and the subsequent get out of bed of modern technology such importance electricity and mobile phones.^[3] Illustriousness pioneers are credited as Felon Clerk Maxwell; Joseph SwanWilliam Armstrong; Thomas Edison; Wilhelm Röntgen; Record. J. Thomson; and Max Planck.^[7]

In , as a sixteen-year-old, Physicist was taken to see upper hand of the minor scientific wonders of the Victorian world: Well-ordered prismmade from a special Nordic crystal.^[7]

Light, the Universe and Everything

The final episode explores the correlation between light, the eye bid the mind and the awaken of technologies such as picture making and cinema.^[3] The achievements refer to John Dalton; Benjamin Thompson; Clockmaker Young; Lord Rayleigh; Joseph Priestley; Thomas Wedgwood; Eadweard Muybridge; Étienne-Jules Marey and Albert Einstein beyond discussed.^[8]

From their knowledge of aptitude blindness, some Victorian scientists held they could prove the professed cultural supremacy of the Ingenuously by measuring differences of tincture perception in different races. Distinction idea was that animals were lower down the evolutionary compass but had better attuned wits than humans. If it could be proved that black followers had better responses to peaceful and colour this would remedy evidence of their inferiority. Manner William Rivers, together with first-class group of Cambridge academics, place off for the Torres Distress to prove exactly this. Rivers used a tintometer but start his original hypothesis was erroneous and that the range insensible "colour difference perception" of leadership islanders was little different non-native that of the English. Just as Rivers returned to England take action spearheaded dissemination of the point that there was no exact evidence to support white supremacy.^[8]

The programme continues and describes Priestley's discovery of photosynthesis.^[8]
