A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.

Summary

This quote suggests that advancements in science are often not accepted immediately by those who oppose them. Instead, change occurs as new generations, who are more open to these new ideas, replace the previous one. It implies that the resistance or opposition to new scientific truths is more likely to come from older generations, who may struggle to let go of conventional beliefs. Consequently, change and progress occur naturally as new generations come to embrace and understand the new scientific truths.
