Teaspoon measuring

[fotch]

.... I was a NACA engineer at a time when a good monthly pay was $300, and had six children in the first 8 years of marriage.

What? Did they fly rockets then or just lit the fuse with a match? :o

Only kidding.

Well from what you said you had not problem with guidance and thrust-to-mass ratios.

NACA does date you though.

And even if you use a scale, be sure to calibrate occasionally.

And not only that, you have to set it to the right unit if the scale is one that allows setting for different systems. You don't want to be measuring grains when you think you are measuring grams.

I think that from the number of kids in 8 years, Patrick's mind was on something else than photography.

I was not aiming at you. I have never had a problem with you or your opinions.

I was aiming at people to pontificate about how much one can screw up the chemistry and still get results, even though the results may not be consistent and then pass it off as The Gospel of Photography.

Steve

And I still ask who, in your inestimable opinion among us APUGers did that? It seems to me that you are among those who claim to know the Divine word about photography.

I love this thread, the remarks from the old timers like me are wonderful.
My 2 cents worth:
Been an engineer since $400.00/month was good pay, ha! An engineer is an applied scientist. I swing
both ways depending on the project. For the chemistry lab and darkroom, I back P.E..
For wooden blocks, I'll go with close, unless tolerances specified. Maybe we should go with the old
pharmacist's 'stricken measure'? Fill a known volume scoop from a bowl of the chemical, then strike it
off level with a business card. Close enough for hand-loading ammunition where +/- 1/10 grain weight
is required. Check with accurate powder scales or triple-beam balance. Remember when graduated
cylinders were real glass and not plastic? They were either marked 'TC' for 'To contain', or 'TD' for
'To Deliver'. That gets us around the rinsing out the last drop, ha! The new teflon graduates are marked
'TC/TD', nothing sticks to them, or so they say.

Carry on gentlemen,

Best regards,

Yeah. I'm a mature 82 years of age. My wife wouldn't leave me alone. I lived and worked through many changes including the one from NACA to NASA without moving to a new desk. That came later. I was asked by the head of the new Space Task Group to design star charts for use as backup guidance for reentry of the Mercury orbital missions. Why? Because I knew about coordinate transformations. I designed a research planetarium including the star projector for human factors research. I --Oh, what the H E double hockey sticks!
Would all this fuss have come about if I had stipulated that my developer should have 0.375 grams Metol, 2.000 grams ascorbic acid, and 7.3333333 grams of sodium carbonate in 1.000 liters water?

BTW, my late beloved wife graduated fro WVU with a 4.0 (or should it be 4.000) GPA and was elected to Phi Beta Kappa.
