• Memory becomes highly underestimated nowadays because of all the various ways to store information “externally”. But in fact, the better we remember our life, the more connections we can make. Memory is also necessary to understand and appreciate many things in life. For example, a person who never read or heard anything about China would not get as much culturally from the trip there as somebody who studied history and architecture of this country for a couple of months.
• One of the people Joshua interviewed for the book tried to increase “subjective” (perceived) life expectancy by improving his memory. The idea is that the more events you remember the longer life seems to be.
• Best chess-players don’t really evaluate all the possible moves logically. Instead, they recognize familiar patterns from other games.
• Cab drivers in London pass obligatory and very demanding exam called “The Knowledge”. It has been found that those who passed it after months of preparation have larger brain region that is responsible for orientation in space. Interestinlgy, brains of “memory champions” are actually quite typical.
• Odyssey and Iliad were initially created the way that made it easier to remember it and paraphrase verbally instead of writing down.
• We can remember almost unlimited number of pictures. At least the fact whether we’ve seen one or not. That is why many memory techniques revolve around transforming other types of information into visual images.
• Also, Joshua acquaints us with several interesting, although ambigous personalities, such as Daniel Tammet, Ed Cooke, Tony Buzan and others.

Mnemonic techniques:

• Some savants naturally use synesthesia (mixing visual, audiotory and other types of perceptions) to enchance remembering and learning through associations.
• “Chunking” is a technique of breaking information into smaller pieces. For example, it is easier to remember a phone number when it is presented as 12-34-56 than when it is presented as 123456.
• Major system. To use this technique, one should use the same consonants for certain numbers. Then, to remember a number, one uses these consonants to form words, which are supposedly easier to remember, by inserting vowels.
• Memory palace. Images are placed in a certain space (appartment, city route or real imagined palace). The more absurd, shiny, sexual and animate the images the better.
• Speech preparation. Try to remember key topics to cover in your speech by visualizing them.
• Remembering texts. Try to feel empathy with an author, to resonate emotionally with a text.
• Deliberate practice: here Joshua gives just another interpretation of the same old study, which almost everybody mentioned recently. The basic conclusion is that people who are best at something did not necessarily spent more time practicing it. But they practised differently.
• In essense, deliberate practise is  an effort to consciously improve one’s level of mastery instead of stopping at the minimum acceptable level (“ok zone”). For example, one might try to type faster than he or she would normally do in order to progress.
•  Deliberate practice also comprises of constant adjustment to feedback and focusing on the most difficult aspects. For example, top violinists practiced most difficult pieces instead of just playing what they already know. Top chess-players re-played best chess games in their heads trying to understand the reasons behind each move. Similarly, Benjamin Franklin learned to write essays by first attempting to cover a certain topic by himself and then comparing the texts to those of best writers.
• Person – action – object system. According to this mnemonic system, one should come up with a person, action and object for each of 100 digits: from 00 to 99. Then, these “PAOs” are used to form sentences in order to remember long lists of numbers.
• Remembering names. Try to come up with a meaningful association. For example, nobody of people studied could remember name “Baker” (no associations) but majority remembered profession “baker” (a lot of associations).
• The reason why people sometimes get an impression that times flies faster might be related to the fact that our life becomes more boring and we get fewer new experiences. In other words, we have less interesting things to remember. So, make your life more memorable!
• Practical advice to remember things in day-to-day life: pay attention. For example, focus on remembering that name instead of just waiting for your time to introduce yourself.

However, it is less clear how to apply it all to learning things that might actually be useful, such as grammar rules, math formulas or just life experiences. Any ideas?

Overall, there are not so many practically applicable things in the book but it is still very interesting to read.

Here is the short interview with an author that covers many of the topics from the book:
