• LEIBNIZ: is the first ai researcher, mental activity is the act of calculation
• ROMANTISCIM: industrial revolution, hard to touch (talent people do that) creative
• DE PRONY: first computers are human, French government they were precise calculations huge factory of manufacturing of trigonometric
• BABBAGE: he build machine replace the human difference engine (1822)
• programable computers build in ww2- general purpose computers
• they have got memory
• IS LIKE MIND: Alan Turing not stated the “is the mind computer?”, he said “can machine think?” first notice
• IS LIKE BRAIN: cognitive revolution (crucial realization) : cognition=symbol manipulators, the new mental chemistry - we are members of broader class
• PSSH necessary is manipulate symbols (cognition is computational) and sufficient for intelligent actions (computers can cognize)

WHAT IS COMPUTATION?

• UNIVERSAL COMPUTATION: INPUT-arrangements of logic gates or neural activity or the von Neumann architecture -OUTPUT
• anything i can do with every different computation i can do another kind of machine, we can translate
• PROBLEM: defining computation is impossible
• the theory of computation: very rich area
• relies on the Turing machine (abstract machine, infinitely long tape read and write on the tape, you are writing if it is q go this and blah)
• UNIVERSAL TURING MACHINE: general purpose machine this is often study this, because:
• extending the basic one is not powerful, notional (nobody builds that), universal model

LIMITS OF COMPUTATIONS

• TRACTABILITY (too long or space)
• COMPUTABILITY (they cannot solve by any computer)
