- Deiter Britz has done a very credible and great service by his
- magnum opus of compilations. Notwithstanding that, science is
- systematized knowledge. People get education from experience.

- {From Webster's [ibid.]}
-
- "experience from the Latin experientia act of trying
-
- 2a: direct participation in events
- 4 : something personally encountered, undergone,
- or lived through"
-
-
- Experience (the quality presumably characterizing an expert)
- is gained by reading, doing, teaching, doing and then realizing the
- mistakes you made.
- Of the other fields I studied [including surgery and
- positron-emission imaging (dual photon)] several just didn't enter
- my mind either by osmosis or just reading.
- Same goes for ciruit design or any of a number of spectroscopies.

- == "There's no point in doing an experiment unless you do it
- == properly, so that you can trust your results 100%,
- == so that you're prepared to put your head on a block in
- == defense of your experiment, etc etc."
-
- The "head should be on the block", with the realization total
- diligence is important, tempered by the understanding that
- retrospect often makes you finally realize the experiment
- could have been done better.
-
- Corrolary: 15 years ago after a decade as an electrical engineer
- (electrophysics), I spent a few years intensively in operating
- rooms, and was performing a below knee amputation on an
- unfortunate end-stage diabetic man. The hospital was fantastic
- at minimizing surgery, and maximizing the length of time a slowly
- deteriorating lower limb would take to reach catastrophe (by
- infection or compromised blood flow). My own engineering
- background made me want to carefully round off the rough bone
- surfaces after sawing through the man's proximal tibia. File.
- File. File. Smooth. Smooth. File. Finally, a tap to my shoulder,
- as the surgical Chief, exasperated andworn of patience, said into
- my ear:
- "Perfection is the enemy of good".
-
-
- It remains insightful and true. And applicable elsewhere.
- An experiment should be very good. but 100%? A priori?
-
- I'll take 3 experiments with clean data, evolving rough-&-ready
- towards a polished experiment over one "100% a-priori" type.
-
- Science and knowledge ring true but tardive.
