 Review of ``Artificial Intelligence: A General Survey''
Lighthill defines a robot as a program or device built neither to serve a useful purpose nor to study the central nervous system, which obviously would exclude Unimates, etc. which are generally referred to as industrial robots.
Lighthill discusses the combinatorial explosion problem as though it were a relatively recent phenomenon that disappointed hopes that unguided theorem provers would be able to start from axioms representing knowledge about the world and solve difficult problems.
Lighthill had his shot at AI and missed, but this doesn't prove that everything in AI is ok. In my opinion, present AI research suffers from some major deficiencies apart from the fact that any scientists would achieve more if they were smarter and worked harder.

 Lighthill Institute of Mathematical Science
James was amongst the Wranglers when he completed the Maths Tripos two years later; he took only pure maths papers, because he said these could be most useful in his planned career in applied mathematics.
Lighthill extended this thinking to the calculation of complicated flows around and within real objects, whether they were aeroplanes, swimming fish, or the ear.
Perhaps we will be reminded of James in future when, like the widow in Charles Kingsley's Westward Ho, we hear the stones crashing and rolling on the beach and think of the group velocity of the waves bringing his energy, spirit and inspiration from somewhere far away.

Sir James was once accurately called "an amazingly extrovert and engaging personality" (THWAITES 1998, 497), and these qualities were undoubtedly reflected in his teaching style when lecturing on mathematics.

Lighthill was a peerless applied mathematician and fluid dynamicist, one of the greatest of this century; of whom Sydney Goldstein, I believe, said that whatever he touched he turned to gold.
Whitham and Lighthill showed that, although the magnitudes of the disturbances were correctly given by linear acoustic theory, the characteristics along which the disturbances propagate were not and had to be correctly accounted for in the nonlinear theory.
Lighthill was able to cleverly model the device and process and, as in so much of his other work, use complex analysis to pull out the relevant answers.

 James Lighthill, 74, an Innovative Mathematician - New York Times
Sir James Lighthill, an innovative British mathematician whose ideas about aerodynamics influenced the design of the supersonic Concorde, died on July 17 while he was trying to swim around the Isle of Sark in the English Channel.
Lighthill was trying to repeat a swim he first made 25 years earlier, for which he applied a scientific approach using a ''two-arm, two-leg backstroke, thrusting with arms and legs alternately.'' His body was found in rough seas off Sark.
Lighthill, who was the Provost of University College, London, from 1979 to 1989 and who held the Lucasian Chair of Applied Mathematics at Cambridge University in the 1970's, a position in which he preceded Stephen Hawking, made early discoveries in mathematical modeling of how creatures swim, fly and move about.

Michael James Lighthill was born in 1924 in Paris.
It is said that Lighthill developed the mathematical ideas for the first of these papers in only two weeks but for 16 months held off submitting it for publication until he had worked and reworked his results making the mathematical implications of more use in jet engine design.
He was famous for his gestures and physical movements during his lectures whether he was demonstrating sound radiation from Monopoles, Dipoles and Quadrupoles, the flight of insects or birds, and the inrush of moist air and its subsequent rapid rise at the eye-wall of a tropical cyclone (from sea level to the stratosphere base).

Remarkably, the Lighthill theory was sufficiently versatile for it to be applied also to problems as diverse as the heating of the sun’s corona and the noise heard under water due to breaking surface waves and splashing drops.
From 1979 to 1989 Lighthill was Provost of University College London, much engaged in fundraising, in new developments in the College, particularly in the biology and biotechnology sides, and in dramatically improving the representation of women in senior posts.

The second spatial derivatives on the right reflect the absence of localized external forces, implying that the nonlinear terms represent internal eddy stresses.
If the Rossby number is small, this weakens the spontaneous imbalance and emission still further (probably from algebraic to exponential smallness), strengthening Lighthill's argument.

 IngentaConnect Lighthill and the triple-deck, separation and transition
In 1953 James Lighthill, conducting an investigation into the potential mechanisms for upstream influence within boundary layers in supersonic flow, published a theoretical approach which explicitly took into account the influence of viscosity on a disturbance to an incident boundary-layer profile.
The physical process he identified is now referred to as a pressure-displacement (or viscous-inviscid) interaction.
This article discusses Lighthill's original paper and then proceeds to show how an appreciation of this interaction mechanism can help in the solution of many other problems in fluid mechanics and especially those of flow separation and late-stage laminar-turbulent transition.
