Question

how was the importance of experiment , observation and calculation established in science?can scientists knowledge progress without them?fast reply guyzzzzzz​

Answer 1

Answer:

Observers use magnifying glasses, microscopes, or telescopes to see things that are too small or far away to be seen, or seen clearly enough, without them. Similarly, amplification devices are used to hear faint sounds. But if to observe something is to perceive it, not every use of instruments to augment the senses qualifies as observational. Philosophers agree that you can observe the moons of Jupiter with a telescope, or a heart beat with a stethoscope. But minimalist empiricists like Bas Van Fraassen (1980, 16–17) deny that one can observe things that can be visualized only by using electron (and perhaps even) light microscopes. Many philosophers don’t mind microscopes but find it unnatural to say that high energy physicists observe particles or particle interactions when they look at bubble chamber photographs. Their intuitions come from the plausible assumption that one can observe only what one can see by looking, hear by listening, feel by touching, and so on. Investigators can neither look at (direct their gazes toward and attend to) nor visually experience charged particles moving through a bubble chamber. Instead they can look at and see tracks in the chamber, or in bubble chamber photographs.
