Saiful investigates how humans as living pulsing machines actually use energy, asking whether it's possible to 'supercharge' the human body and increase its performance. Live experiments explore everything from the explosive potential of everyday foods, to what we put into our bodies (and what comes out!), as well as how we measure up to the machines we use every day. Saiful even experiments on himself, showing images captured inside his own stomach. Every single one of us is an incredibly sophisticated energy conversion machine, finely tuned over millions of years of evolution. So will we ever be able to improve the human body's performance? Can we ever do more with less energy?

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.

How do we learn properly so we can be right all the time? How can we know that we know, when we don't know what we don't know?
