Priyamvada Natarajan Quotes
Scientific knowledge is, by its nature, provisional. This is due to the fact that as time goes on, with the invention of better instruments, more data and better data hone our understanding further. Social, cultural, economic, and political context are relevant to our understanding of how science works.

He was addressing the misunderstanding that many laypeople and most anti-evolutionists have that if Evolution is only a theory why put so much stock in it. The layman often uses the word “theory” in opposition to “fact.” But to the scientist theories are of different types—those that are as of yet speculation and those for which a strong body of evidence exists. Evolution, like Relativity, has a huge amount of evidence supporting it. Yet in time every good scientist knows that all these proven theories will be modified with new knowledge. Relativity has been demonstrated as having errors initially by Einstein himself. The essence of these things are true although elements change. The early law of gravity is the best example. We know that it is wrong in many, circumstances—in space for example. But it, none the less, is fundamental to much analysis and with our much more sophisticated understanding of it we still talk of the “Law” of gravity even though we realize that it is not quite correct in all circumstances.
Priyamvada (Priya) Natarajan is a professor in the departments of Astronomy and Physics at Yale University. She is noted for her work in mapping dark matter and dark energy, particularly with her work in gravitational lensing, and in models describing the assembly and accretion histories of supermassive black holes. She authored the book Mapping the Heavens: The Radical Scientific Ideas That Reveal the Cosmos.
