logic

two kinds of logic

scientific method

it is like the note book...in the note book everything needs to be written down..so the problem wouldnt get more complicated and you get lost and confused. Sometimes the act of writing down the problem makes it easier. The purpose of the scientifc thinking is to make sure that you are thinking in something you dont know.

logical statements

conclusions from the results of the experiments

stating no more than the experiment has proved

observed results of the experiments

predicted results of the experiment

experiments designed to test each hypothesis

An experiment never fails it only fails to achieve predicted results.

hypothesis

Think of many hypotheses as you can, then design experiments to test them to see which

are true and which are false.

statement of the problem

stating nothing more than what you are sure of

inductive

if the cycle goes over a bump and the engine misfires, and then goes over another bump and the engine misfires, and then goes over another bump and the engine misfires, and then goes over a long, smooth stretch of road and there is no misfiring, and then goes over a fourth bump and the engine misfires, one

can logically conclude that the misfiring is caused by the bumps. That is induction: reasoning from particular experiences to general truths.

start with observations of the machine and

arrive at general conclusions. For example, if the cycle goes over a bump and the

deductive

example

from reading the hierarchy of facts about the machine, the mechanic knows the horn of the cycle is powered exclusively by electricity from the battery, then he can logically infer that if the battery is dead the horn will not work. That is deduction.

refrences

start with general knowledge and predict a specific observation
