Thus Galileo invented the telescope, and Newton came upon the legislation of gravitation. the sensible use of the discovery whilst grew to become to the heavenly our bodies served to substantiate the reality of the discovery.
Discovery and invention might be, and sometimes are, united because the soul is to the physique. The union of the 2 produces a number of innovations. hence the invented electro-telegraph involves the mix of discoveries of convinced legislation of electrical energy with an gear, during which indicators are communicated to distances by way of electric influence.
Inventions and discoveries don't precede or stick to one another so as. The tool could be made sooner than the legislation which govern its operation are came across. the invention may well lengthy precede its edition in actual shape, and either the invention and variation may perhaps ensue together.

This brief enumeration will serve to point the various roads alongside which innovations and the discoveries of technology progress.
