The Mind Map is a technique to memorize things for long time and remember them very easily. The technique was introduced for the first time by Tony Buzan. He did years of researching about brain rules and people to study how long they can memorize things and remember them.
Before I get into the technique I'd like to say something about the Curve of Forgetting that is based on thousands of scientific experiments on people:
Suppose you are in a class and you got 2 hours information. Immediately after class the people can remember almost 80% of information. One day later without review the percentage descends to 60%. After two days this will be 40%. After one month we will remember only 20% of information. Here is the curve of forgetting:
As you see if we don't reinforcement the information we will loose them very soon. The Mind Map helps us to memorize in a very practical method and after that we could be able to review and memorize the information so simple.
How could we do it:
First of all you need to study the information and pick up keywords. Then try to construct them like a tree and put every keyword on a branch. It is so better that you sketch branches like curves. Because of Tuny Buzan researches the brain neural networks are like curves. After you build the tree you must memorize the keywords and information loudly. The next reviews could take fast and very few times.
So, the power of the technique is: If you reinforcement immediately after you got them you will be able to remember almost 100% of it for next day, then you review it in next day you will be able to remember it for a week. One review after a week makes your ability to remember for a month and so on.
Below is one of my mind map sample. Its about to a 40 hour marketing course only in a single map and here is the power of mind map.
