- Looking inside the Intel 8087, an early floating point chip, I noticed an interesting feature on the die: the substrate bias generation circuit. In this article I explain how this circuit is implemented, using analog and digital circuitry to create a negative voltage.
- Aztec philosophy (Wikipedia)
Aztec philosophy was a school of philosophy that developed out of Aztec culture. The Aztecs had a well-developed school of philosophy, perhaps the most developed in the Americas and in many ways comparable to Ancient Greek philosophy, even amassing more texts than the ancient Greeks. Aztec cosmology was in some sense dualistic, but exhibited a less common form of it known as dialectical monism. Aztec philosophy also included ethics and aesthetics. It has been asserted that the central question in Aztec philosophy was how people can find stability and balance in an ephemeral world.
