Patterned Planet

   2018    Nature    HD
Earth's surface is covered in weird and wonderful patterns. The Australian outback is covered in pale spots, the work of wombats; a clearing in the endless green canopy of the Congo rainforest has been created by an incredible elephant gathering; and the twists and turns of the Amazon make a home for rehabilitated manatees. This is our home, as we've never seen it before.

What are We Really Made of

   2011    Science
What is the universe made of? If you answered stars, planets, gas and dust, you'd be dead wrong. Thirty years ago, scientists first realized that some unknown dark substance was affecting the way galaxies moved. Today, they think there must be five times our understanding of the universe and the nature of reality itself has drastically changed over the last 100 years - and it's on the verge of another seismic shift. In a 17-mile-long tunnel buried 570 feet beneath the Franco-Swiss border, the world's largest and most powerful atom smasher, the Large Hadron Collider, is powering up. Its goal is nothing less than recreating the first instants of creation, when the universe was unimaginably hot and long-extinct forms of matter sizzled and cooled into stars, planets, and ultimately, us. These incredibly small and exotic particles hold the keys to the greatest mysteries of the universe. What we find could validate our long-held theories about how the world works and what we are made of -- or, all of our notions about the essence of what is real will fall apart.

The Stilwell Brain

   2019    Medicine
A single microscopic brain cell cannot think, is not conscious, but if you bring in a few more brain cells, and a few more, and connect them all, at a certain point, the group itself will be able to think and experience emotions and have opinions and a personality and know that it exists. How can such astonishing things be made from such simple ingredients? Well, answering that question means learning not only who we are but, more importantly, how we are.
Today, using what neuroscientists know so far, we are going to make a town function like a brain, using people as neurons.

Off the Scale

   2012    Science
The human eye can see extraordinary detail, but the eye of a needle held at arm's length is pretty much at the limit of our vision. Anything smaller is simply invisible, at least to the naked eye. But what if we could see this hidden world all around us in greater detail and magnification than ever before? How different would our familiar surroundings then seem? Richard Hammond explores the astonishing miniature universe all around us, revealing that small is not only beautiful, it can also be very, very powerful. From seeing the microscopic changes to ice crystals that can trigger an avalanche to watching in horror the invisible aftermath of a sneeze on a commuter train and learning how the surface of an ordinary-looking plant hides an astounding secret that will make walking on the moon safer, Richard harnesses cutting-edge technologies to transport the viewer into a spectacular micro realm.
