As someone who is interested in science, and science experiments,labwork and demonstrations, I am pleased to find that Popular Sciencemagazine has placed their articles into a searchablearchive. One of my favorite authors of these articles is Kenneth M.Swezey. He used to set up the experiments, get volunteers to performthem, take photos and write it all up in the many articles he authoredover the years. He also collected these articles into several books:"After Dinner Science," "Science Magic," and "Chemistry Magic." I happento own these three books; I've had them since I was a young kid, andthey're among my most prized possessions. Now this same information isavailable to people who don't own the books (they're long out of print,but still covered by Copyright). Check out the archive, and startsearching for cool things like "spinthariscope," "X-rays," "Chlorine,""Magnesiun," and whatever else you seek. http://www.popsci.com/archive-viewer
I find it both fascinating and appalling when I go out onto the Web andread about what this century has in store for us:On one hand, we face increasing climate chaos, possible drought orhurricanes, the rising probability of a massive earthquake inCalifornia, the end of cheap energy and along with it affordable food.We hear dire predictions of the mess that consumer culture will make ofthe planet as it spreads to developing nations. What if everyone inChina DOES want to drive a car? What if the banks fail? What if myretirement savings disappears? Oh, and don't forget the global pandemicthreat! Bird flu, swine flu, dog or cat flu - it's just a matter oftime before a really nasty bug appears, and circles the globe before wecan do anything to stop it. On the other hand, technological progress on many fronts continues toaccelerate. Nanotechnology, a mastery over matter, and the ability toprogram molecules at will, is getting ever greater traction in labsaround the globe, and despite the hype of its early days may deliver, in theareas of medicine and energy, quite soon. Even artificial intelligence,whose painfully slow development caused a generation of disappointment,is finally beginning to appear - in your cell phone!A world of highly-efficient solar energy farms, or solar satellitesbeaming energy to receiving antennas on the ground; super-medicine thatcan repair the damages of the aging process as easily as swallowing acapsule of nanobots; unlimited, healthful food, synthesized on the spotfrom an unending stream of component molecules, using templates based onthe world's finest organic ingredients and culinary practices. Will my retirement years look like something out of Soylent Green? Orwill I simply not retire, but find fulfilling work that is not driven bythe need to make a buck, but to serve humanity, while learning andcreating, following my own unending and ever-changing interests? Will Ifinally learn to play the piano? Should I be getting involved in a local "transition plan" that seeks toavoid financial and human catastrophe in my local area? Should I plant avegetable garden? Should I abandon the house I live in, and move into anRV? Should I head to the countryside, where at least the farmers'markets may still have food?And what about my kids? Should the two I have in college continue topursue their degrees, or will their education be rendered useless bytechnological or social change?What is the prudent course? I'm trying to formulate one for myself andmy family. Starting with the extrememly short-term, and working outwardto a rest-of-my-life planning process, I'm trying to cover my bases. First, the home disaster kit, with food and water for three or more daysfor my family. Then I'll put together a bug-out kit, which is somethinglike a set of camping supplies, again with plenty of food and water,that we can take with us if we have to get out of town. This might beneeded if (when) the "big one" hits, and our neighborhoods go up inflames, fueled by large quantities of natural gas escaping from the gasmains. I'm also thinking of dropping off simple one-sheet disaster planningleaflets around my neighborhood, to try to get others to prepare. Idon't want to be the only one with food and water, surrounded by severalhundred families who don't! I'm starting to take these steps toward Hacking the Future!
