Just about every solid, liquid, or gas in the world as we know it begins with reactions between individual atoms and molecules. Host David Pogue dives into the transformative world of chemical reactions, from the complex formula that produces cement to the single reaction that’s allowed farmers to feed a global population by the billions.
How do you know you’re real? Is existence all just a big dream? Has some mad scientist duped us into simply believing that we exist? James Zucker investigates all of these questions (and more) in this mind-boggling tribute to René Descartes’s "Meditations on First Philosophy."
What are the origins of life? How did things go from non-living to living? From something that could not reproduce to something that could? Earth is estimated to be about 4.5 billion years old, and for much of that history it has been home to life in one form or another. Our planet is teaming with life, from the highest mountain to the deepest ocean; life is everywhere. But what was the firing pistol that started the evolutionary race? How did material go from non-living to alive? It's one of the most fundamental and difficult questions that has challenged us since the beginning of time.
