Just How Small is an Atom?

The interactive Scale of the Universe shows us how minuscule and gargantuan elements in our universe can be. We know that atoms, the basic unit of matter, are small but just how small are we talking about?

Scientist and teacher Jonathan Bergmann answers that question in this quick animated chemistry lesson using blueberries, grapefruits, and football stadiums as metaphors.

You can find many more educational videos at TED-Ed.

Conception to Birth, Visualized

Alexander Tsiaras is a whiz at scientific visualization. In his early days, he created lenses for microscopes, most notably for the one that captures the very first images of human eggs in an in vitro fertilisation (IVF) program.

In his presentation from a TED conference in 2010, the scientist talks about how the instruction sets used in creating a human being are so complex that they are beyond our comprehension. It’s mathemagical. He also shows a visualization of the development of the human fetus. See Conception to Birth, Visualized below. Be warned, there are some graphic images of the “expulsion” process.

Nick Veasey’s X-Ray Vision

Nick Veasey isn’t a traditional photographer. In the same vein as microscopist Alan Jaras who uses a scanning electron microsope to create a story about exploration, Veasey also makes uses of medical equipment to produce some unconventional art.

Veasey left the world of standard photography behind when he was asked to X-ray a cola can for a television show. Since then he has created X-ray photographs of everyday objects from mp3 players, toys, and clothes to all manner of plant life and animals. His experimentation has led to view the innards of larger subjects like motor vehicles, an office building, and even to capture the anatomy of a Boeing 777!

Veasey uses industrial x-ray machines and in the case of the airplane, 500 individual films were processed and then joined together on the computer to create the composite shot. For his “human” subjects, he has the option of using skeletons in rubber suits or cadavers. He reportedly has eight hours in which to pose and photograph the cadaver before rigor mortis sets in. I don’t know about you, but I find that a little macabre. In any case, the results are amazing to see. This is what he has to say about his art:

My work is real. X-Ray is an honest process. It shows things for what they are, what they are made of. I love that. It balances all that glossy, superficial bollocks. I’m real and straightforward. And so is my work.
