概要
What if you could store every movie ever made, every book ever written, and every song ever recorded inside a container no larger than a sugar cube?
This isn't science fiction—it is the reality of DNA, a biological archive so dense that a single gram can hold 215 million gigabytes of data.
In this premiere episode, we explore the "Encoding of Life," tracing how our bodies manage an astonishing volume of information, from the stable genetic archives of our ancestors to the dynamic, millisecond-fast flashes of neural memory.
We begin with the "bits and wonder" of information theory, following Claude Shannon’s revolutionary work at Bell Labs that turned information into something quantifiable.
You'll discover the "twisted ladder" of the DNA double helix, first captured in the quiet precision of Rosalind Franklin’s Photograph 51, and learn how its four-letter alphabet acts as a "write-once, read-many" archive for your physical traits.
But the blueprint is only half the story. We also dive into the "rewriteable overlay" of epigenetics, the flexible chemical tags that annotate your genetic script based on your diet, stress, and environment—even leaving marks that can be passed down through generations.
