Blue Planet Prank Radio So what you're seeing here is that the chicken is hotter than its surroundings. Now, heat is a highly disordered form of energy, so the chicken is radiating disorder out into the wider universe. By converting chemical energy into heat, life transforms energy from an ordered to a disordered form, in exactly the same way as every other process in the universe. COCKEREL CROWS In fact, every single human being can generate , times more heat per kilogram than the sun. And it's by converting so much energy from one form to another that life is able to hang on to a tiny amount of order for itself. Just enough to resist the inevitable decay of the universe. Blue Planet Prank Radio So it's no accident that living things are hot and export heat to their surroundings. Because it's an essential part of being alive. Living things borrow order from the wider universe, and then they export it again as disorder. But it's not precisely in balance. They have to export more disorder than the amount of order they import. That is the content of the Second Law Of Thermodynamics. And living things have to obey the Second Law because they're physical structures, they obey the laws of physics. Just by being alive, we too are part of the process of energy transformation that drives the evolution of the universe. We take sunlight that has its origins at the very start of time, and transform it into heat that will last for eternity. So, far from being a paradox, living things can be explained by the laws of physics. The very same laws that describe the falling of the rain and the shining of the stars. The dragonfly draws its energy from proton gradients, the fundamental chemistry that powers life. But the real miracles are the structures they build with that energy. Borrowing order to generate cells. Arranging those cells into tissues. And those tissues into the intricate architecture of their bodies. So we've developed a quite detailed understanding of the underlying machinery that powers these dragonflies, and indeed all life on Earth. And whilst we don't have all the answers, it is certainly safe to say that there's no mysticism required. You don't need some kind of magical flame to animate these little machines. They operate according to the laws of physics, and I think they're no less magical for that. Yet the dragonfly will only maintain this delicate balancing act for so long. Because all living things share the same fate. Each individual will die. But life itself endures. DRAGONFLIES BUZZ This is because there's something that separates life from every other process in the universe.
