But the title is great:
Submarines do not swim
???? Based on my favorite quote on #AI: “The question of whether machines can think is about as relevant as the question of whether submarines can swim.” (Edsger Dijkstra
Why don’t we say submarines swim?
Can submarines swim? That depends on how we define swimming. Swimming is
usually understood as moving bodily appendages in such
as way as to generate locomotion through an aquatic medium. Submarines do move through an aquatic medium, and there could be a curious debate on whether a propeller is a bodily appendage.
Does a submarine swim or float?
How do submarines float and sink? Using Archimedes’ Principle, it is clear that a change in mass of an object affects how much liquid has to be displaced. In submarines, this is controlled by ballast tanks. When the tanks are empty, the submarine has less mass and it
floats like
a normal ship.
Can you swim up from a submarine?
Once the pressure in and outside the ship match, the hatch will
lift off open
, and they can swim out of a fully filled chamber into open ocean.” … In addition to getting SEALs off the ship, lockout trunks can be used for the entire crew to escape in case the submarine is downed.
What does a submarine do underwater?
A submarine (or any boat) can
float when the mass of water that it displaces (pushes out of the way)
is equal to the mass of the boat. This displaced water causes an upward force called buoyancy. Buoyancy acts in the opposite direction to gravity, which would pull the ship down.
Who address the question whether machines can be intelligent?
The phrase “The Turing Test” is most properly used to refer to a proposal made by
Turing
(1950) as a way of dealing with the question whether machines can think. According to Turing, the question whether machines can think is itself “too meaningless” to deserve discussion (442).
What happens if a submarine goes too deep?
The name is foreboding and fairly self-explanatory; it’s when the submarine goes so
deep the water pressure crushes it
, causing an implosion. … Retired navy captain James H Patton Jr said a submarine reaching crush depth, “would sound like a very, very big explosion to any listening device”.
A nuclear submarine can dive to a depth of
about 300m
. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters, or about 1.3 miles. The average depth of the world’s oceans is 3,790 meters, or 12,400 feet, or 2

How thick is a submarine hull?
Making the hull. 4 Steel plates,
approximately 2-3 in (5.1-7.6 cm) thick
, are obtained from steel manufacturers. These plates are cut to the proper size with acetylene torches.
Has anyone escaped a submarine?
All of the 72 crew made it to the surface but only
15 survived
with the rest swept out to sea by the tide and lost. … Of the Soviet submarine’s 69 crew, 34 of those who made the ascent to the surface later died from hypothermia, heart failure or drowning.
How do submarines not crash?
Avoiding collisions in shallow water requires different skills. Submarines are fitted with bottom-sensing sonar but mostly rely on maps of coastal waters. They
navigate using an imaginary “pool of errors”
. “The longer you are without a proper fix then your pool of errors expands,” says Tall.
How long can submarines stay underwater?
The limits on how long they can stay underwater are food and supplies. Submarines generally stock a 90-day supply of food, so they can spend
three months
underwater. The diesel-powered submarines (not now used by the United States Navy) had a limit of several days submerged.
How deep could the first submarines go?
The first practical submarine was built in 1620 by Cornelis Drebbel under the employ of King James I. A leather-covered 12-oar rowboat, Drebbel’s submarine was reinforced with iron to withstand water pressure, and was functional, submerged to a depth of
fifteen feet beneath the River Thames
.
How do submarines get air?
Oxygen onboard a submarine is released either
through compressed tanks, an oxygen generator
, or by some form of an ‘oxygen canister’ that works by electrolysis. Oxygen is either periodically released throughout the day at specific time intervals or whenever the computerized system detects a reduction in oxygen levels.
What is the longest a submarine has stayed submerged?
The longest submerged and unsupported patrol made public is
111 days (57,085 km 30,804 nautical miles)
by HM Submarine Warspite (Cdr J. G. F.
Why is AI so hard?
AI-complete problems are hypothesised to include
computer vision, natural language understanding
, and dealing with unexpected circumstances while solving any real-world problem. Currently, AI-complete problems cannot be solved with modern computer technology alone, but would also require human computation.
