: We don't actually make 'parts' - we are a testing laboratory that tests coated 9and often painted) steel sheeting, the stuff that eventually gets roll formed and put on the roof etc. It sounds like fascinating work. And the problem is quite interesting. For a similar problem, consider how you would set up a fence to contain the maximum number of sheep with the minimum amount of fencing. From http://www.netjeff.com/humor/item.cg...icianJokes.txt (Although you can find this joke all over the web now. It's an oldie but a goodie.) An engineer, a physicist, and a mathematician are shown a pasture with a herd of sheep, and told to put them inside the smallest possible amount of fence. The engineer is first. He herds the sheep into a circle and then puts the fence around them, declaring, "A circle will use the least fence for a given area, so this is the best solution." The physicist is next. She creates a circular fence of infinite radius around the sheep, and then draws the fence tight around the herd, declaring, "This will give the smallest circular fence around the herd." The mathematician is last. After giving the problem a little thought, he puts a small fence around himself and then declares, "I define myself to be on the outside!" And some more examples he http://www.phy.ilstu.edu/~rfm/107F07/EPMjokes.html |

Place L over G, F over D, and E over J (and K). The only sample where the long end is not parallel to the rolling direction is Sample L The maximum height of this first strip is 330mm, and the first cut is 940mm long. Turn the sample, and cut off consecutively a 125mm strip (H), 4 x 95mm strips (A, B, C, G & L), a 120mm strip (F & D) , a 177mm strip (E, J & K) and lastly a 125mm strip (I) leaving 13mm x 330mm area - discard. Cut off top 30mm from Samples H & I and discard Cut off top 60mm from Samples A, B & C and discard Cut off top 5 mm from section LG and discard Cut off top 60 mm from section LG. This is now Sample L. Remaining part is Sample G Cut off top 165mm from section FD. Top is Sample F, bottom is Sample D Chop off top 13 mm of section E J K & discard Chop off top 120mm. Retrieve, turn, and chop off top 52mm. This is now sample E Turn JK, chop off top 77mm - this is Sample J Of the remaining part, turn and chop off top 2mm and discard . Remainder is Sample K. I hope I got the description right as its the best I can do in prose - diagrams are easier but I don't kow how to do one in text. I just double the pattern if I need to test both sides. The "the boss isn't watching" solution I have found is a little different, but don't have time to post it now. |

*snip* Part of being a good boss is knowing when to get lost for a while so things can get done. I hope I can remember this if I ever get to be a boss. My current boss is a a very precise 'cross the t's, and dot the eyes' sorta guy for himself, but knows better than to get in my way - if I can get the same results he does in the same time and using the same amount of materials, then he trusts me enough to know that however I get things done, I get the same outcome, even if I may not have been 'working hard' for the same length of time he would have. Previous boss had a horrible habit of turning up at precisely the wrong time, I swear he had a 'goofing off' detector fitted into the back of my neck when I wasn't looking and caught me taking short cuts, not following the 'standard procedure' or worse - drinking coffee and chatting outside of the official times allocated for breaks (never mind the previous 6 hours straight I had worked just before hand and either had to have a break of collapse of exhaustion). And the very worst thing he did was 'just call me when you start, I'll come down and give you a hand" and *expected* to be called down and got all ****y and insulted when I didn't. He had no clue, not being experienced at doing what I do, used to ask the dumbest questions, object when I deviated at all from the written procedure even though everyone actually doing the practical side of the job knew that how thigns worked in practice was not the same as theory, and used to slow me down horribly (not to mention really tick me off!). He then had the audacity to complain about how slow I was compared to everyone else even though he had spent the whole day with me, watching me like a hawk and making it utterly impossible for me to slack off in the slightest. He never did catch on to the idea that if I was tacitly 'allowed' to slack off when I wanted, I actually got more work done at a better quality, because I was happier. Besides, I figure if the bosses can have a weekly meeting with each other than just happens to occur at a local club that just happens to have food and beer and the meeting although ostensibly a 'lunchtime' meeting more often than not seems to extend for the whole of friday afternoon, I am entitled to 5 minutes of gossip at the water cooler on occasion.

Yowie Oldest grandson is starting his third year in college studying accounting and business management. He was pretty astonished when I told him about the second office I worked in. They had mostly women and a few men (exchange student types) that did basic bookkeeping and computer entry tasks. Some of them has been at their jobs for years. And each group of five or six was 'managed' by a young man whose job was to manage them. The young man usually had a two year business degree, was wearing his first suit and tie, and had no idea of how to do the jobs he was expected to manage. There was a fairly large turnover it those ranks, so new ones were coming in all the time. The first thing their new "managees" always had to do was to train them how to go about their jobs. I'm sure you all realize these guys were paid quite a bit more than those who 'worked for them'. But it would have been unheard of to promote one of the perfectly capable women who had been there for years. This in 1966 and 1967. Jo |

I have the same problem- I work in concentrated bursts of energy then might sit back for 5 minutes or chat to a colleague before getting the next wind up. I do all my work and take on extra when needed no problem but I do need perhaps 5 minutes an hour to recharge and the law of sod decrees that if I've just worked flat out for 55 minutes in minute 56-59 when I'm having a drink of water or just clearing my head from the last job and getting ready for the next, which basically doesn't count as "work" since I am thinking and it does not show (and probably is not encouraged in my job anyway) the boss will come in and wonder what I am doing! I always have to point out what I just did and what I am about to do to pacify her. But that;s the way I work best, some other people plod through, some are better at certain times than others (I always get more done in the afternoon myself) but try to get a boss to understand that?

I have a lot of trouble concentrating when I hit a roadblock at work, and I often have to take some time to get away from it. It's more than 5 minutes, that's all I'll say Also, this happens often, so I find myself working on-again, off-again throughout the day. I do get my work done, though, and I meet my deadlines, so I don't feel guilty about it. I've been in the workforce for decades and my style of working has always been like this. When I'm on a roll, I work fast, and that makes up for the slow start. I've always been this way. As a kid, I used to find in-class assignments really hard to get started on. I'd stare out the window and daydream, occasionally trying to start the assignment, but not getting anywhere. Meanwhile, everyone else would be scribbling away. Eventually, I'd hit on an idea and finally get started, and then I'd be really into it, when suddenly the teacher would tell us it was time to stop. I would have to hand in an unfinished paper. The teacher would usually make me stay after school to finish it, telling me that if I didn't spend so much time staring out the window and "dreaming", I wouldn't have to stay after to finish.

Real Life Puzzle
Mind work is fundamentally different from assembly work. [...]
I recognize in myself the arrival of "Flow", a Zen-like mental state that requires some time to achieve but when it's there, I can achieve phenomenal rates of concentration and, hence, productivity. You are using the same amounts of brain doing physical-coordination tasks as conceptual ones. There isn't that big a difference. I get zoned out in the way you describe when playing music, and used to when I did photography in a big way, entirely absorbed in framing the perfect shot. But the experience was the same when I worked in the most repetitive job there was in a vast industrial slaughterhouse. I was standing up on a gantry in front of a conveyor with four different kinds of organs whizzing past at a rate of about two a second. My job was a drop two types of organ down the catfood chute and let the others carry on to be turned into something else. I was doing that single task for two hours at a stretch with no pause. I got into such an interesting state of mind it was the job I most looked forward to. (One of my favourite books ever: Peter Currell Brown, "Smallcreep's Day" - it's good on that sort of thing. So is the poetry of Gary Snyder). ==== j a c k at c a m p i n . m e . u k === http://www.campin.me.uk ==== Jack Campin, 11 Third St, Newtongrange EH22 4PU, Scotland == mob 07800 739 557 CD-ROMs and free stuff: Scottish music, food intolerance, and Mac logic fonts ****** I killfile Google posts - email me if you want to be whitelisted ****** |
