too bad
"would have been a fantastic and vital discovery if I had been a good biologist. But I wasn’t a good biologist. We had a good idea, a good experiment, the right equipment, but I screwed it up: I gave her infected ribosomes—the grossest possible error that you could make in an experiment like that. My ribosomes had been in the refrigerator for almost a month, and had become contaminated with some other living things. Had I prepared those ribosomes promptly over again and given them to her in a serious and careful way, with everything under control, that experiment would have worked, and we would have been the first to demonstrate the uniformity of life: the machinery of making proteins, the ribosomes, is the same in every creature. We were there at the right place, we were doing the right things, but I was doing things as an amateur—stupid and sloppy"

The issue of reduction... This is a big part of the issue of trying to understand the brain biologically at the moment..
"paramecium, it looked like a network of jackstraws. As the drop of water evaporated, over a time of fifteen or twenty minutes, the paramecium got into a tighter and tighter situation: there was more and more of this back-and-forth until it could hardly move. It was stuck between these “sticks,” almost jammed. Then I saw something I had never seen or heard of: the paramecium lost its shape. It could flex itself, like an amoeba. It began to push itself against one of the sticks, and began dividing into two prongs until the division was about halfway up the paramecium, at which time it decided that wasn’t a very good idea, and backed away. So my impression of these animals is that their behavior is much too simplified in the books. It is not so utterly mechanical or one-dimensional as they say. They should describe the behavior of these simple animals correctly. Until we see how many dimensions of behavior even a one-celled animal has, we won’t be able to fully understand the behavior of more complicated animals"

knowing or KNOWING
"After a lot of investigation, I finally figured out that the students had memorized everything, but they didn’t know what anything meant. When they heard “light that is reflected from a medium with an index,” they didn’t know that it meant a material such as water. They didn’t know that the “direction of the light” is the direction in which you see"

humans and machines memory
"A week or two after, I was thinking a great deal about how the brain works compared to how a computing machine works—especially how information is stored. One of the interesting problems in this area is how memories are stored in the brain: You can get at them from so many directions compared to a machine—you don’t have to come directly with the correct address to the memory. If I want to get at the word “rent,” for example, I can be filling in a crossword puzzle, looking for a four-letter word that begins with r and ends in t; I can be thinking of types of income, or activities such as borrowing and lending; this in turn can lead to all sorts"

let it all hang
"In summary, the idea is to try to give all of the information to help others to judge the value of your contribution; not just the information that leads to judgment in one particular direction or another."
