For those, like me, who can't rely on being given a home smoker this Christmas, you can build your own approximation with just a roll of tin foil and a big wok or pan for which you have a lid.

It takes a fearless, unflinching love and deep humility to accept the universe as it is. The most effective way he knew to accomplish that, the most powerful tool at his disposal, was the scientific method, which over time winnows out deception. It can't give you absolute truth because science is a permanent revolution, always subject to revision, but it can give you successive approximations of reality.
