Numerical Optimization and Computational Optimal Transport

The anthropologists are busy, indeed, and ready to transport us back into the savage forest, where all human things... have their beginnings; but the seed never explains the flower.

The space of time in which a great work can now be accomplished is not marvellous. Brain, muscle, materials, and the means of rapid transport are instantly at command. If one has capital and a well-considered plan, the thing does itself. But that which is wonderful and which I can scarcely believe, although I have been in the midst of it, is the noble, artistic result which has come from the work of American artists who have had only a few months' time to prepare those very designs for the great buildings of the Exposition which have actually been executed with little change from the sketches which were presented in February, 1891.

The essence of air transport is speed, and speed is unfortunately one of the most expensive commodities in the world, principally because of the disproportionate amount of the power required to achieve high speed and to lift loads thousands of feet into the air. This is strikingly illustrated by the fact that while an average cargo ship, freight train and transport aeroplane are each equipped with engines totalling about 2,500 H.P., the ship can carry a load of about 7,000 tons, the train 800 tons and the plane only two and a half tons.
