Teachers don't just teach; they can be vital personalities who help young people to mature, to understand the world, and to understand themselves. A good education consists of much more than useful facts and marketable skills.

One test should not govern how students are judged or how teachers are judged. This will not benefit education.

Watching cold fusion is like watching water boil in slow motion. First, sufficient deuterium has to penetrate the palladium electrode. This can take a few weeks. Then, if excess heat is generated during the next month or two, accurate temperature readings require extreme precautions to exclude environmental effects.

Scaremongering is an age-old political ritual. There are public officials who have benefited by playing up the 'hacker threat' so that they can win approval by cracking down on it.

As cyberspace matures into a totally immersive experience, I'm betting it will turn out to be fully odor-enabled.

If low-temperature fusion does exist and can be perfected, power generation could be decentralized. Each home could heat itself and produce its own electricity, probably using a form of water as fuel. Even automobiles might be cold-fusion powered.
