With the aid of the Radiophonic Workshop, Laithwaite experiments with sound and speech before we journeying with Alice to the "wood of thought" to enquire whether the Universe as a whole has a preferred 'direction'. Is the Universe left or right-handed, for example, and what answers does the phenomenon of electromagnetism reveal? -- Professor Eric Laithwaite (1921-97) presents his second televised series of CHRISTMAS LECTURES exploring the world of engineering, titled 'The Engineer Through the Looking Glass'. A sequel to his 1966 series, 'The Engineer in Wonderland', Laithwaite was the first person to present two series of Lectures on national television. His overriding theme running through this series is that "Science is exciting, curiosity its bait". Just as Lewis Caroll’s Alice peered down the rabbit hole and went through the mirror, Laithwaite describes the engineer’s target as the "seemingly impossible". As he states in his programme notes: "There may be no crown at the end for those who step through the glass, as there was for Alice, but if the delight is there, the journey itself is the reward". His six lectures explore the varied work of engineers across gravitation, inertia and electromagnetism, including the controversial fourth Lecture where Laithwaite used the behavioural gyroscopes in an attempt to challenge the validity of Newton’s Laws of motion and the laws of thermodynamics. -- Join this channel to get access to perks:    / @theroyalinstitution   Subscribe for regular science videos: http://bit.ly/RiSubscRibe The Ri is on Twitter:   / ri_science   and Facebook:   / royalinstitution   and TikTok:   / ri_science   Listen to the Ri podcast: https://podcasters.spotify.com/pod/sh...
