Living Things Renew Themselves
Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to react in such a way that it may maintain itself against the blow, much less so as to render the blow a contributing factor to its own continued a...

Lecturing is Easy, Teaching is Hard
Lecturing after a fashion is easy enough ; teaching is a very different affair. ... The transmission of ideas from one mind to another, in a simple unequivocal form, is not always easy ; but in teaching, the object is not merely to convey the idea, but to give a lively and lasting impression; something that should not merely cause the retention of the image, but in such connection as to excite another process, ' thought.' 1

notesPlanting ideas in students' heads of different backgrounds and experiences is a difficult task.

Genetics Grew Up an Orphan
In a sense, genetics grew up as an orphan. In the beginning botanists and zoologists were often indifferent and sometimes hostile toward it. 'Genetics deals only with superficial characters', it was often said. Biochemists likewise paid it little heed in its early days. They, especially medical biochemists, knew of Garrod's inborn errors of metabolism and no doubt appreciated them in the biochemical sense and as diseases; but the biological world was inadequately prepared to appreciate fully ... 1 notes
notesGeorge Beadle in 'Genes and chemical reactions In Neurospora' describes out botanists, zoologists, and biochemists were uninterested in genetics as it dealt simply with the transmission of characteristics between individuals while there were greater things to study in the field.

Universal Intelligence Cannot Exist
We conclude that there cannot be a strongly cohesive network of
communicating, unifying intelligences through the whole universe if (1) such
galactic civilizations evolve upward from individual planetary societies and if (2)
the velocity of light is indeed a fixed limit on the speed of information
transmission, as special relativity requires (i.e., if we ignore such possibilities as
using black holes for fast transport: See Chapter 39). Such a universal intelligence
is a kind of god that cann... 1 notes
notesAt best, aliens advanced enough to be gods could only exist at a galactic level.

The Evolution of Culture
What science is, I think, may be something like this: There was on this planet an evolution of life to the stage that there were evolved animals, which are intelligent. I don't mean just human beings, but animals which play and which can learn something from experience (like cats). But at this stage each animal would have to learn from its own experience. They gradually develop, until some animal coudl learn from experience by watching, or one could show the other, or he saw what the other on...Although Feynman calls it "time-binding," this sounds very much like memetics.
