Alexander Tsiaras has made a career of using advances in visualization technology to offer vivid tours of the human body. His books have taken readers inside the human heart, the kidneys and vascular system, and also human reproduction. Back in 2002, Tsiaras published From Conception to Birth: A Life Unfolds, a book that offers a “visual diary of fetal development.” Now, nearly a decade later, he brings that visual diary to video at a conference affiliated with TED.

What’s more amazing is how he describes what he’s learned from doing these complex visualizations. Twice he talks about the “divinity” of the process of human development, and about how, even as a mathematician, the extraordinary complexity of human development is many orders of magnitude more than he can comprehend. The video is amazing and is certainly worth sharing with friends and on Facebook/Twitter. Click here to link to the video now.
