Well, 11 of 14 people got last week's puzzler right – you can build an entire computer using nothing more than two-input NAND gates (and actually, you can build one from two-input NOR gates as well). The fact that so many of my readers knew this answer certifies my audience as being mostly comprised of fairly extreme geeks...
This week's puzzler is back to history – science history...
What was the last name of the scientist who (in the early 1900s) was notoriously associated with the notion that acquired characteristics of an organism could be inherited? This scientist's views persuaded the leader of a major country, and caused Darwinian inheritance to be officially banned there for many years.
No fair googling!
