Segment 1 — The Cold Open
In the late 1870s a high-wheel bicycle reached the rider only after a craftsman filed, brazed, and trued every joint by hand, leaving the finished machine priced well beyond a clerk’s yearly pay and dangerous enough that only fit young men attempted it. ...

Wheat that once collapsed under heavy grain now yields two to three times more per acre because breeders shortened the stalk instead of adding still more fertilizer.
Segment 1 — The Cold Open
For centuries a wheat plant that received extra nitrogen simply grew taller until its own weight toppled it flat in the field. Norman Borlaug and his colleagues refused to accept that limit. ...
