— counterfactual reasoning for past and future: ‘what if’ questions and mental scenarios in the context of preparation; ‘what if’ questions that seem to serve fantasizing; ‘what if’ questions that pertain to the past versus the future; and ‘what if’ questions that relate to self versus others. Are they all different? Perhaps not as much as it would seem,
with all promoting simulations and imagery, possibly creating ‘memories’ that can be applied in future situations.

I'm reading "Why don't students like school?" The book is quite good because it shows certain cognitive principles, (mostly based on how human memory works) that make teaching (and learning) easier.

Nevertheless, I find certain things disturbing. For example, the author says that to teach abstract ideas you need to show a lot of examples:
To Help Student Comprehension, Provide Examples and Ask Students to Compare Them.

Let's use the Newton's principle and make the rule universal. That is, imagine that students become really good learners, by exploring examples and comparing them to each other. How the hell are they going to learn proofs? No wonder that even the best high school students when they go to university have no concept of proving their ideas logically, instead of by "here's another example."

The NSA director says that a nation-state used Wikileaks to influence the US elections.


I wonder what this state might be...

Опять я достиг состояния, когда чувствую, что ничего не понимаю. Надо перестать откладывать и начать писать книжку; заодно и разберусь. Вот сейчас прямо все брошу и начну.
