Jean remains happily retired and otherwise unemployed, bedbugs intimidate me, and I’m still researching if light can be slowed to 38 mph.
The man from ELCA Chicago became a good friend on our first meeting. He’d served with the church in South Africa, he wanted to know more about the Plaster House, heard we had some insight, and so we were able to fill in a lot of historical gaps for him. He didn’t know we’d been to the Maasae Girls School, a place he’s been to a number of times and just loves. He’d met Sarah! at the Plaster House and fell in love with the hundreds of wounded children (not really wounded, but children needing physical correction). OK, he’s my friend! We updated (we being she) him on Operation Bootstrap and gave him more history than he needed; he absorbed it like a sponge. He wanted us to talk about Africa and the ELCA and we were more than willing. If we weren’t needed at the bedbug site, we’d probably still being talking.
I don’t want to talk about bedbugs, but know this: we took off our clothes and washed them as soon as we got home. May none of you ever know what makes me go “Uuuuuuu!”
Regarding yesterday’s the speed of light, here’s some of what my crafted Wikipedian research revealed: The speed of light is normally about 186,000 miles/second. Scientists succeeded in slowing it down to 38 mph by shooting a laser through extremely cold sodium atoms, which worked like “optical molasses” to slow the light down. Danish physicist Lene Hau led a combined team from Harvard University and the Rowland Institute of Science which succeeded in slowing a beam of light to about 17 meters per second (that’s 38 mph) and later (2004) researchers at UC-Berkeley slowed the speed of light traveling through a semiconductor to 9.7 kilometers per second. Hau later succeeded in stopping light completely and developed methods by which it can be stopped and later restarted. Their intent is to develop computers that will use only a fraction of the energy of today’s machines and has nothing to do with the Renton S-curves (which also can be stopped and sometimes restarted). Personally, I’ve always stopped light by using the switch on the wall.
I would guess slowing light would produce a lot of energy, maybe almost as much as it took slowing it down. Who’d have guessed the slowing needed sodium atoms? Does stopped light still look like light or does it look like the dark? I won’t mention this subject again unless I find the final answer, which will, undoubtedly, be God, anyway. Love,
