The Half-Life of Facts
Why Everything We Know Has an Expiration Date
Available Now

Welcome to the website of Samuel Arbesman. I’m a complex systems scientist and writer.

I write and think about knowledge in our age of scientific and technological change and what that means for society. My book The Half-Life of Facts is out now in paperback and I’m currently working on my next book.

I have a blog at Wired Science called Social Dimension, and am on Twitter at @arbesman.
