Think of science this way: you are researching a technology that requires 100 beakers. Assuming you can afford it, at full (100%) science you make
10 beakers per turn, meaning you will research the technology in 10 turns at full science. By running 10% science you make 2 beakers, so it will take 50 turns to finish research, but since the maximum research time is 40 turns, you will essentially get the last 10 beakers for free. If you start at 10% and go 3 turns like that, you will have accumulated 6 beakers. Switching to 100% will then give 10 more per turn, but you still have to get 100 beakers. See what I mean?
