which way is better to expanding memory in ourselves?

Answer 1

There is no one way; and what works for one may not work for another. But here are few ways I use.

Exercise the mind; do puzzles both mental (like Sudaku) and physical (like Rubik's Cube).

Use mnemonics to help guide your memory. Like Roy G. Biv, which guides us to the spectrum of light (red, orange, yellow, green, blue, indigo, violet). Or Columbus sailed the ocean blue in 1492...which rhymes.

A math technique called units analysis can also help you remember math formulas.

When introduced to a new person, try to associate that new name with some prominent feature of that person. So the next time you see the person, that feature will help you remember the name. Example: Tom Blair is the new person and name. As you are introduced, imagine beating Tom's nose on his forehead...like a tom tom. And a nose is for air, like Bl..air.

Answer 2

You can also try memory association through a familiar place. For example, picture your house. Start at the front door and associate a silly thing at that place. For example, to memorise force X time = change in momentum - try Darth Vader (force) doing his TIMES table on a skateboard (momentum), holding on to your door handle. The sillier the better.

If you then enter your house you can have the next silly thing in the entrance hall. That way you can memorise a sequence of things simply by walking through your familiar place. You can then associate a room with a particular subject, or even a whole house with a subject.

I have a keen interest in amateur dramatics - and I can learn a script very quickly using this technique. The great thing about it is that you can work out from the visual image what's going on. Why was Darth vader on a skateboard - oh yes...
