Behind an Extraordinary Memory

By now, most of you should know that I am a die-hard fan of Scientific American. Here is yet another interesting article about extraordinary minds . The interviewee, Daniel Tammet, is special in his own right. He is a mildy autistic linguist who can recite the first 22 514 decimal places of the mathematical constant Pi . Here are a few takeaways from the interview: Visualization improves memory. Instead of treating numbers as boring static strings, view them in dynamic, multi-dimensional shapes and forms. This technique also works beautifully with learning vocabularies. Clustering also improves memory. If you break a series of numbers into smaller chunks (of 3 or 4), your brain can better handle them.

In fact, the more exaggerating the imagery, the better the results. In Daniel's words, he used to "da

Book Review: A Brief History of Time

Thus the theories behind quantum mechanics, relativity, black holes, time travel, and wormholes can all be comprehended by the average person. Every time I pick up this paperback, I feel humbled by the grandeur of our mysterious universe. Needless to say, the origin of the universe may just provide a clue to the birth of life.

Before the dawn of the 20th Century, the Michelson-Morley experiment was conducted to substantiate the existence of a substance called "ether." Instead, it created a shock wave for the entire scientific community. Throughout the next twenty years, numerous futile attempts were made to explain the surprising results of the experime
