The Paradoxes of Color Temperature

Posted in Physics, Science, Seattle, Sustainability on February 22nd, 2009 by leodirac – Comments Off on The Paradoxes of Color Temperature

Last week I went to the Indoor Sun Shoppe in Fremont and got a couple new CF bulbs for the house. I love their selection — they have everything from tiny 7W candelabra bulbs to these massive 150W bulbs that look like death-rays. A giant 105W bulb (pictured) is now trying to make my monstera deliciosa’s home in the living room a little more like tropical mexico and less like winter-in-seattle. In addition to a huge range of powers, they also clearly show you the color temperature of each bulb. Some of my friends have avoided CF bulbs because of…

The summary of the book on the publisher’s site is great: The first full biography of Paul Dirac, the greatest British physicist since Newton – and one of the strangest geniuses of the twentieth century, who may have suffered from autism.

How to stop getting phone books

Posted in Community, Transhuman Morality on February 1st, 2009 by leodirac – 2 Comments

A while ago I posted about how to stop getting Dex phone books delivered in Seattle. Unfortunately doing that wasn’t enough to stop all the dead trees from showing up on my doorstep. Now there’s a new grass-roots service called Yellow Pages Goes Green which handles this nation-wide across all providers of phone books.

If you use the internet or your phone to look up people and businesses, I encourage you to visit http://www.yellowpagesgoesgreen.org/stop-yellow-pages/ and stop the unsolicited deliver of unwanted phone books. Even if recycled, these books waste…
