Humanity’s potential seems limitless. But could we become as powerful as God?
S5E09 • Through the Wormhole • Science
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.

New research sheds light on the functions of fat and bone. In fact, fat and bone are not static tissue but release signaling molecules to dynamically interact with the other organs and support our health. Fat was found to control our appetite and the bone to work to keep us young.
Just 92 elements made up the world, but the belief that were only four - earth, fire, air and water - persisted until the 19th Century. Professor Al-Khalili retraces the footsteps of the alchemists who first began to question the notion of the elements in their search for the secret of everlasting life. He reveals the red herrings and rivalries which dogged scientific progress, and explores how new approaches to splitting matter brought us both remarkable elements and the new science of chemistry.
