Check out the Wikipedia discussion on handedness.?ÿ All sorts of scientific studies have been made on the subject.?ÿ Lefties are twice as likely to die in combat than righties.?ÿ Certain diseases show up in greater numbers with lefties.?ÿ Studies have been conducted on babies still in the womb for signs of handedness then compared to their post-birth handedness.
Interesting information.
Some of the statistical differences, like for bone fractures, can be hypothetically explained by the world being designed for easier use by right hand people. Some correlations could easily be explained by a common cause in fetal development. Others are harder to explain.
If you run that linen through the washing machine enough times you will have some really nice handkerchief material!
Aren't there actually two different types of drafting linen, I've run across what seems like real linen and something refered to as linen that has a "plasticy" feel to it, somewhere between linen and mylar.
I had the opportunity to take several ruined linen plots home. After the washings, each of them produced great polishing cloths. Glass cleaning was awesome since the linen seems to produced no lint.
JA, PLS, SoCal
I got 8 yes. 8 no.
Avoiding autocad regen made me laugh. A definite YES
GPS at night in the winter, day in the summer was not an option. Summers were hot, and off road at night scary. And the car batteries? Yes, carry car batteries and happy to do it.?ÿ
Overnight processing was Geolab. Yes. And in the morning work on the results, and start it again as I left. For weeks. Glad to do it.
I ran traverse with 3800 and T2 for years pre gps, the computer was the house VAX.
and stake out with HP41 and coordinate list in hand. Rayouts calced in the field.?ÿ
I never had to chain more 600 ft ?ÿ

@flga-2-2 We mostly had the 8" floppies, but the "big" one was a 5mg Winchester drive! Oooooo...that was 1986, just before HP came out with their Unix workstations. They, and the software Holguin produced for them, were junk. Not what we were looking for, that's for sure. Damn shame too....
I have a cogo program for 41. Original and iPhone emulator. Dates back to about 1988. Took about 8 mag cards to load. 100 point data base. I relied on that for my pls exam.
Still use it, absolutely. And still write routines for it. Like for the HP3805 ppm calculation.?ÿ
Same here, man.?ÿ I tried forever to figure out how I could adapt a Leroy device so I could use my left hand.?ÿ But I ended up adapting instead.
Linen, ugh.?ÿ First time, no one had told me that you can't spit to help erase, makes a big burn-out.?ÿ That was after someone else had drafted about 90% of the plan, thought my boss was going to fire me right then
Done Leroy Lettering? No.
Used a planimeter to "buggy" areas or calculated cuts/fills using average end areas? No.
Used a Lenker rod? Yes. A marvelous invention for construction sites!
Used a right-angle/90 degree prism for rough grade stakeout or station/offset work? Yes. Both single and double.
Used a top mount or stand alone (HP3805/3810) EDM? Yes.
Used a dip needle? No.
Drafted on linen? No.
Carried a tack ball? Yes.
Used an "Acu-Arc" for drawing curves? No.
Hand generated contour lines interpolating between adjacent data points? No. Used a rubber band to do it?
Avoided a "regen" in Autocad at all costs because of how long it took? No. The computers I used had enough RAM.
Started GPS baseline processing before leaving the office hoping it would be done when you got back in the
morning? No.
Did GPS observations at night because that was when enough satellites would be passing over? No.
Used hand signals to "talk" for things like cuts/fills for marking stakes? Yes. I didn't need no stinkin' radio!
Watched a pen plotter in amazement as it plotted in what seemed like a random order? Yes.
Used a HP-41c/cv/cx to traverse/inverse and watched the "goose" fly across the screen? Yes. The R/S key.
@richard-germiller?ÿ ?ÿ Yes, you did not know it was linen until you had to erase the same thing twice.?ÿ
Yes to all of the OP items, as well as David Hines ones.?ÿ ?ÿHere's a couple more:
Used a tellurometer?ÿ like Cubic DM-20 or Tellurometer CA-1000
Used a Rhoads Arc and cloth tape to do cross sections or topo
Did precise taping with tension handles and taping bucks
Ran first order levels with invar rods and turtles
Did angles only trigonometry to cross a canyon or body of water
precise chaining. I??m jealous. I bought a K&E 100?? invar base tape, and calibrated my SuperHiway chains. (I always call them chains.)!
How many of you have:
Done Leroy Lettering??ÿYes
Used a planimeter to "buggy" areas or calculated cuts/fills using average end areas??ÿNo
Used a Lenker rod??ÿYes
Used a right-angle/90 degree prism for rough grade stakeout or station/offset work??ÿYes
Used a top mount or stand alone (HP3805/3810) EDM??ÿYes
Used a dip needle??ÿKind of, used a compass
Drafted on linen??ÿlinen was a little before my time, velum and Mylar yes.?ÿ I once worked in a cartography studio where we etched on a coated mylar film for work in photographic reproduction
Carried a tack ball??ÿStill do
Used an "Acu-Arc" for drawing curves? Yes
Hand generated contour lines interpolating between adjacent data points? Yes Used a rubber band to do it??ÿNo
Avoided a "regen" in Autocad at all costs because of how long it took? Yes.?ÿ Thank the divine pasta for 'limits'
Started GPS baseline processing before leaving the office hoping it would be done when you got back in the morning? Yes.?ÿ Waited that long for AGPS to download from the 4000SSi let alone processing
Did GPS observations at night because that was when enough satellites would be passing over? Yes
Used hand signals to "talk" for things like cuts/fills for marking stakes? Yes
Watched a pen plotter in amazement as it plotted in what seemed like a random order? Yes
Used a HP-41c/cv/cx to traverse/inverse and watched the "goose" fly across the screen? Yes

Just a few I can recall from my 45 years in this profession.
