“Indeed, one could define science as reason’s attempt to compensate for our inability to perceive big numbers.”Scott Aaronson A wonderful quote, eh? Well, I think it is. Anyway, for some odd reason, today I was thinking about the mathematical operation of tetration. Many people have heard about addition, multiplication (which is interated addition) and exponentiation [...]

Quantum Entanglement Reminds Me of Douglas Adams’ Fairy Cake Idea

According to the NYT, quantum computers, still in their early development, have reached the ten qubit milestone. To give you some perspective, a forty qubit quantum computer can perform ten trillion calculations, ten teraops, simultaneously. Forty atoms sitting in a nuclear magnetic resonance rig can rival the power of the largest supercomputers. A thousand atoms [...]

By Popular Request, Unnecessary Nano Links

Some folks–well, one at any rate–have expressed surprise that I don’t have more links and rants about nanotechnology on my site. So to address that issue: BN nanostructures stronger, lighter than steel Just to give a little perspective, I first heard about nano back in 1987 when a friend told me about it. I read [...]
