Knowing Versus Doing

“We should not give up because there is no unified field theory of software engineering. The elements may not be easy to implement, but they are relatively simple, especially when compared with the study of proteins. ... The problem is not that we do not know enough. The problem is that we do not practice what we know.”

Yourself Yesterday

“Compare yourself to yourself yesterday, not to younger people who aren’t you. Everyone progresses at a different rate, so don’t let anyone else make you feel behind. You probably don’t even know where exactly you’re going, so feeling behind doesn’t help.”

Microsecond Nanosecond

“In total desperation, I called over to the engineering building, and I said, 'Please cut off a nanosecond and send it over to me'... At the end of about a week, I called back and said, 'I need something to compare this to. Could I please have a microsecond?”

Infinity

“It’s generally a bad idea to compare infinity to infinity, because the outcome depends on just how you define the comparison, so any conclusion you draw from such an exercise becomes physically ambiguous.”

Software Not Physical

“We clearly do not now have an engineering capability comparable to those based on the physical sciences. Such a capability is what is implied by the term software engineering. But software is not a physical system, it is a description of what one describes how a given physical system (a computer of some sort) should act. Thus software is more akin to engineering drawings, either maintained on paper or within a computer. ... So probably it is incorrect to assume software engineering should be considered as a sibling in the family of the physical science based engineering disciplines.”

Plato

Cave

“Compare the effect of education and of the lack of it on... human beings [prisoners] living in an underground, cave like dwelling... They've been there since childhood, fixed in the same place, with their necks and legs fettered, able to see only in front of them... Light is provided by a fire... A low wall has been built, like the screen in front of puppeteers... there are people [puppeteers] along the wall, carrying all kinds of artifacts that project... These prisoners see... [only] the shadows that the fire casts on the wall... Then the prisoners would in every way believe that the truth is nothing other than the shadows of those artifacts.”

Willard_Van_Orman_Quine

Science as a Tool

“As an empiricist I continue to think of the conceptual scheme of science as a tool, ultimately, for predicting future experience in the light of past experience. Physical objects are conceptually imported into the situation as convenient intermediaries - not by definition in terms of experience, but simply as irreducible posits comparable, epistemologically, to the gods of Homer. For my part I do, qua lay physicist, believe in physical objects and not in Homer's gods; and I consider it a scientific error to believe otherwise. But in point of epistemological footing the physical objects and the gods differ only in degree and not in kind. Both sorts of entities enter our conception only as cultural posits. The myth of physical objects is epistemologically superior to most in that it has proved more efficacious than other myths as a device for working a manageable structure into the flux of experience.”

Comparing Averages

“Averages have their place. If you’re comparing two different groups of people... as opposed to comparing two individuals from each of those groups — then the average can be useful.”

Scale of the Crime

“For there are things for which one is guilty even if one might offer excuses - simply because the scale of the crimes is so overwhelming that by comparison any human excuse pales to insignificance."

Process of Scientific Discovery

“The process of scientific discovery is cautious and rigorous, not by abstaining from hypotheses, but by rigorously comparing hypotheses with facts, and resolutely rejecting all which the comparison does not confirm.”

Automated Evaluation

“The system automatically computed efficiency ratings for each worker by comparing the amount of time it took to complete a job had been priced. Such calculations with the amount of time for which it could have been generated only by a computer system, since 'we could never have enough clerks to compute these kinds of ratios.' The ratings were considered management information and were not accessible to the craftworkers. Many foremen cautioned against taking the ratings at face value. The most experienced craftsperson frequently was loaded with the most difficult assignments. That individual might show the worst efficiency rating simply because his or her assignments were the most complex and required more than the assigned time.”
