Reason: There are salaries to be bankrolled, lab equipment to be bought and field research to be financed. Without funding science can’t simply progress.
Evidence: It is scientifically proven that position on Earths surface is given by two coordinates; latitude (degrees below or above the equator) and longitude (degrees east or west of a given south meridian). Before two thousand years ago, the determination of latitude was intractable problem because when travellers used to travel over land or sail across oceans, they had to know the coordinates of their destination as one could easily be lost at sea or might be in deep forests. Not only the globetrotter but also the governments and kings were facing lot of problems such as treasure fleets from Latin America, trading ships from the Far East, naval vessels were all getting lost and running out of food and water and ships were also running aground on reefs or into cliffs instead of findings safe harbors. In order to overcome this relatively straightforward matter, the crowned heads and government offered huge rewards for anyone who could solve this vexing problem. The various Royal prizes and particularly the British Longitude Act, spawned a host of eccentric would-be solutions to longitude. But ultimately correct and workable method had been first proposed by German Frisius, the Flemish astronomer, the map maker. In 1530 he proposed time-keeping as the solution to the problem of longitude. The last but not least , to some extent it’s true that science can be done without much money at all but on the flip side of coin, wealth can play an important role as oxygen plays in a human being, As there are many research topics in science that are not so cheaply addressed. For instance in 2007, 25 million dollar prize was offered for the invention of a viable technique for removing carbon dioxide from the atmosphere.
Conclusively, funding can influence the way of science by encouraging research on some topics and pointing away from others.
