“It is important to distinguish the difficulty of describing and learning a piece of notation from the difficulty of mastering its implications. […] Indeed, the very suggestiveness of a notation may make it seem harder to learn because of the many properties it suggests for exploration.”

“Everyone has learning difficulties, because learning to speak French or understanding relativity is difficult.”

“With the computer and programming languages, mathematics has newly-acquired tools, and its notation should be reviewed in the light of them. The computer may, in effect, be used as a patient, precise, and knowledgeable "native speaker" of mathematical notation.”

“If we truly learn from history, the current reality should not suggest otherwise. It is ironic, because history proves that we have learned nothing.”

“The properties of executability and universality associated with programming languages can be combined, in a single language, with the well-known properties of mathematical notation which make it such an effective tool of thought.”

“I suggested that liberals might have even more difficulty understanding conservatives than the other way around, because liverals often have difficulty understanding how the Loyalty, Authority, and Sanctity foundations have anything to do with morality.”

“The mind unlearns with difficulty what it has long learned.”

“These computing machines had already been designed, and some built, by {[w|Vannevar Bush}}, Norbert Wiener, and others, and were almost ready-made for the job. These scientists, as well as others such as von Neumann, Shannon and Bigelow, were in a position to see that machines of an electronic kind were ideally suited to carry out the whole of the operations of range-finding and location without any human intervention whatever.
These electronic computing machines were already developed to a very high degree of efficiency for the solution of mathematical equations, and some technical difficulties had led to the suggestion that a process of scanning, similar to that used in television, might be incorporated into the computer. Another innovation was the use of binary notation rather than decimal notation as in the early Harvard Mark I computer.”

“The Dirac notation, though originally applied to the propagation of single particles, also applies to describing the propagation of ensembles of coherent, or indistinguishable, photons.”

“He [Kant] suggested that experience may be not at all simple, but always complex, so that the very possibility of the experience which seems to the empiricist the absolute foundation of knowledge may depend on the presence in it of a factor that will have to be acknowledged as a priori. This factor issues from the nature of the mind that has the experience, and introduces into experience all that distinguishableness, that arrangedness, and that describable form, without which it could not be conceived as apprehensible or intelligible, that is, as an experience at all.”
