[The launch of Nautilus, the world's first atomic submarine] marked a transition in naval warfare—a transition as sudden as that associated with the Monitor.

Fleets are not confined to the ocean, but now sail over the land. … All the power of the British Navy has not been able to prevent Zeppelins from reaching England and attacking London, the very heart of the British Empire. Navies do not protect against aerial attack. … Heavier-than-air flying machines of the aeroplane type have crossed right over the heads of armies, of million of men, armed with the most modern weapons of destruction, and have raided places in the rear. Armies do not protect against aerial war.

His [Marvin Minsky’s] basic interest seemed to be in the workings of the human mind and in making machine models of the mind. Indeed, about that time he and a friend made one of the first electronic machines that could actually teach itself to do something interesting. It monitored electronic “rats” that learned to run mazes. It was being financed by the Navy. On one notable occasion, I remember descending to the basement of Memorial Hall, while Minsky worked on it. It had an illuminated display panel that enabled one to follow the progress of the “rats.” Near the machine was a hamster in a cage. When the machine blinked, the hamster would run around its cage happily. Minsky, with his characteristic elfin grin, remarked that on a previous day the Navy contract officer had been down to see the machine. Noting the man’s interest in the hamster, Minsky had told him laconically, “The next one we build will look like a bird.”

I feel that the recent ruling of the United States Army and Navy regarding the refusal of colored blood donors is an indefensible one from any point of view. As you know, there is no scientific basis for the separation of the bloods of different races except on the basis of the individual blood types or groups. (1942)

I think that each town should have a park, or rather a primitive forest, of five hundred or a thousand acres, either in one body or several, where a stick should never be cut for fuel, nor for the navy, nor to make wagons, but stand and decay for higher uses—a common possession forever, for instruction and recreation. All Walden Wood might have been reserved, with Walden in the midst of it.

Neither the Army nor the Navy is of any protection, or very slight protection, against aerial raids. We may therefore look forward with certainty to the time that is coming, and indeed is almost now at hand, when sea power and land power will be secondary to air power, and that nation which gains control of the air will practically control the world.

Never, I believe, did a vessel leave England better provided, or fitted for the service she was destined to perform, and for the health and comfort of her crew, than the Beagle. If we did want any thing which could have been carried, it was our own fault; for all that was asked for, from the Dockyard, Victualling Department, Navy Board, or Admiralty, was granted.

The Royal Navy’s unique ability to combat scurvy was said by one naval physician to have doubled its performance and contributed directly to Britain’s eventual defeat of the French and Spanish fleets at Trafalgar in 1805. (It also meant that British sailors became known as “limeys.”)

The Secretary of the Navy [Josephus Daniels] has decided that the science of aerial navigation has reached that point where aircraft must form a large part of our naval force for offensive and defensive operations. Nearly all countries having a Navy are giving attention to this subject. This country has not fully realized the value of aeronautics in preparation for war, but it is believed we should take our proper place.
Statement on the future of U.S. Naval Aviation made on the eve of World War I.

We claim to be more moral than other nations, and to conquer and govern and tax and plunder weaker peoples for their good! While robbing them we actually claim to be benefactors! And then we wonder, or profess to wonder, why other Governments hate us! Are they not fully justified in hating us? Is it surprising that they seek every means to annoy us, that they struggle to get navies to compete with us, and look forward to a time when some two or three of them may combine together and thoroughly humble and cripple us? And who can deny that any just Being, looking at all the nations of the earth with impartiality and thorough knowledge, would decide that we deserve to be humbled, and that it might do us good?
