Hunting for Helium in the 1632 Universe
In the 1632 universe, helium is mentioned repeatedly as an alternative to hydrogen as a lift gas for airships. While providing slightly (7%) less lift, it has the advantages of being non-flammable and having about half the permeation rate of hydrogen (so it leaks out...
Photography in the 1632 Universe: Part 3, Light in a Box
Unless you are content with a mere photoprint (which captures silhouettes of opaque objects and filtered images of translucent ones placed upon illuminated film), you also need an optical system for creating an image of the scene at the "film plane." Typically, that...
Photography in the 1632 Universe: Part 2: Touching the Rainbow

The Art of Secret Communication: Part 3, the One-Time Pad and the Generation of Random and Pseudorandom Numbers
The only cryptographic system that is perfectly secure is the one-time pad (OTP): in essence, a system in which every plaintext message is encrypted in a different, truly random key whose length is equal to the length of the message, and which is never reused. In...
