Dave,
I couldn't have won at a better time. I recently purchased a 5 acre lot and I need to remove lots of trees, stumps and sticker bushes so my builder can build a new 3 bedroom ranch home. Approximately 10 weeks ago I herniated a disk in my back and I haven't been able to do a lot of work on our lot so I have plenty of work for Clumpy and Kloumpios to do this week.
George

Subject: [TN] Element Quiz Answer
The Question:
This element was known to ancient civilizations (at least 5500 BC). A pure bar of this element will "cry" when bent due to the twinning of its crystal structure. One of the early Latin words for this element was "plumbum candidum". A major commercial application for a compound containing this element is the stabilization of PVC plastics.The International Maritime Organization has a worldwide ban of a compound containing this element.
Which element is being described?
The Answer:
The element is Tin (Sn). The Latin word "stannum" originally meant an alloy of silver and lead, and came to mean 'tin' in the 4th century BC - the earlier Latin word for it was plumbum candidum, or "white lead". Tributyltin was used as additive for ship paint to prevent growth of marine organisms on ships, with use declining after organotin compounds were recognized as persistent organic pollutants with an extremely high toxicity for some marine organisms. Many nations now restrict the use of organotin compounds to vessels greater than 25 m (82 ft) long. A tinplate canister for preserving food was first manufactured in London in 1812.
Speakers of British English call them "tins", while speakers of American English call them "cans" or "tin cans". One derivation of such use is the slang term "tinnie" or "tinny", meaning "can of beer" in Australia. And of course, we utilize tin in our solder alloys for our electronics!
The winner of the quiz is George Wenger and will get the services of Clumpy and Kloumpios for the week.

- I still have vinyl and a turntable, though 78s were a bit before my time. The guys get here just in time for our summer plant shutdown, so their workload will be minimal. We all deserve a break, right? Happy 4th of July, everyone!
Week 63 Matthias Mansfeld, Mansfeld Elektronik PCB Design and Assembly -I don't know what they'll do at the both Toms, but if they can use Internet, then the two Toms arrange their time schedule and I'll give the boys access with VPN to my CAD software and they can do some layout stuff at night. Cadstar or Altium, whatever they prefer...
Week 63 Tom Carroll, Boeing
- Wow a three way tie is awesome. I would ask that Clumpy and Kloumpios arrive on Tuesday to help celebrate my daughter's 21st birthday and then come along as we attend Part 1 and 2 of Harry Potter and the Cursed Child on Broadway on Wednesday. I know the boys will be able to explain some of the secrets behind Harry's powers, I just hope they will share it with my daughter. Should be a good time for all.
Week 63 Tom Granat
