Experimental science has been around since Ancient times, but systematic experiments are something quite new. They probably didn’t have the technical tools we have today. Of course they don’t have electronic computers. Motor racing if everything is under control you are just not driving fast enough poster. But they have math and mechanical scales. And all scientific observations are required to be represented in precise mathematical terms. ‘Measuring what is measurable, and making the immeasurable’, said Galileo Galilei, one of the most important scientists of the sixteenth century. He also said that the nature book is written in the language of mathematics. And all these new experiments and measurements have facilitated new inventions.
