Question 457527
.


Edwin,


about 40 years, I worked as a computer programmer, developing computer codes for my own researches 
and for customers.  After many years of working, I learned the truth: a good programmer knows better 
than a customer, what the customer needs.


Working about 15 years at this forum, I can say similarly that I know better than any visitor 
what this visitor wants to say or wants to express in his post.


Physicists who work every day with elementary particles on accelerators and observe tracks
of these particles, identifying known and unknown particles, have their professional proverb
"It's shameful to doubt when you know for sure".
