You know that the matters of the subject are in the book but can you pull out where the matters are exactly? So, there are certain techniques to increase your memory and store things in it.One such technique is called Mind Palace.

Yes, it is.Have you ever wondered what happened to the things that you read when you were young. When you were reading you would have had a perfect memory of the subject. But over time you could have forgot it. But the fact is you never forget anything you read. All the matters you learn are stored somewhere in your brain. You only don't know how to access it. Our memory stores everything in a random manner. So, it becomes difficult to access it at a later point of time. Imagine a book without page numbers and index.

Is our Memory Power really improvable?

This idea made me believe that our memories are really improvable. 

Citing costly memory-related inconveniences suffered by average individuals, a science journalist chronicles his own struggles with chronic forgetfulness and his life-changing year in memory training, in a guide that shares historical lore and ancient memory techniques.

Science & Nature

Foer's unlikely journey from chronically forgetful science journalist to U.S. Memory Champion frames a revelatory exploration of the vast, hidden impact of memory on every aspect of our lives. On average, people squander forty days annually compensating for things they've forgotten. Joshua Foer used to be one of those people. But after a year of memory training, he found himself in the finals of the U.S. Memory Championship. Even more important, Foer found a vital truth we too often forget: In every way that matters, we are the sum of our memories. Moonwalking with Einstein draws on cutting-edge research, a surprising cultural history of memory, and venerable tricks of the mentalist's trade to transform our understanding of human remembering. Under the tutelage of top "mental athletes," he learns ancient techniques once employed by Cicero to memorize his speeches and by Medieval scholars to memorize entire books. Using methods that have been largely forgotten, Foer discovers that we can all dramatically improve our memories. Immersing himself obsessively in a quirky subculture of competitive memorizers, Foer learns to apply techniques that call on imagination as much as determination-showing that memorization can be anything but rote. From the PAO system, which converts numbers into lurid images, to the memory palace, in which memories are stored in the rooms of imaginary structures, Foer's experience shows that the World Memory Championships are less a test of memory than of perseverance and creativity. Foer takes his inquiry well beyond the arena of mental athletes-across the country and deep into his own mind. In San Diego, he meets an affable old man with one of the most severe case of amnesia on record, where he learns that memory is at once more elusive and more reliable than we might think. In Salt Lake City, he swaps secrets with a savant who claims to have memorized more than nine thousand books. At a high school in the South Bronx, he finds a history teacher using twenty- five-hundred-year-old memory techniques to give his students an edge in the state Regents exam. At a time when electronic devices have all but rendered our individual memories obsolete, Foer's bid to resurrect the forgotten art of remembering becomes an urgent quest. Moonwalking with Einstein brings Joshua Foer to the apex of the U.S. Memory Championship and readers to a profound appreciation of a gift we all possess but that too often slips our minds.

Foer is the younger brother of New Republic editor Franklin Foer and novelist Jonathan Safran Foer. He is the son of Esther Foer, president of a public relations firm, and Albert Foer, a think-tank president. He was born in Washington, D.C. and attended Georgetown Day School. He then went on to graduate from Yale University, where he lived in Silliman College, in 2004.Foer is married to Dinah Herlands, a medical student at Yale, whom he met while an undergraduate at Yale. Foer sold his first book, Moonwalking with Einstein: The Art and Science of Remembering Everything, to Penguin for publication in March 2011. He received a $1.2 million advance for the concept when he was just 22 plus a movie option.
