Memory

Memorization does not always have to be boring. There are various techniques that we can try to memorize things.
Creating meaningful groups:
This is a technique that one can use to memorize certain things, for instance, to remember the cranial bones, there is a well-known sentence wherein the first letters of each word represents the first letter of the bones in the cranium: Old People From Texas Eat Spiders: Occipital, Parietal, Frontal, Temporal, Ethmoid and Sphenoid. The reason we remember the sentence more easily than the actual words we want to memorize is that they are funny, weird or just more interesting than the actual

Memory Palace Technique: 
Though I am not a big fan of this technique, this might work for people who try to create mental images for the things they learn. In fact, one study even showed that people who use this technique can remember more than 45% of a 50-item list after only one or two "mental walks"*.
What this technique says:

1. Imagine a place with many rooms that you can easily remember such as your home or office. This is what we call the 'Memory Palace'.
2. Make a mental image of a specific route that you go through such as once you enter your home through your front door,  you go to the living room, then to your kitchen etc. Always take the same route in your mental path when you have to use this technique.
3. Try to associate things that you need to remember with things in your 'memory palace'.
4. Try to be imaginative and make some funny, interesting mental images of those items in those places from (1).
5. Repeat the practice as this technique is a bit slow in the beginning but is quite effective after you get used to creating mental images.

For instance, if you have to remember items to buy at a grocery store, you can imagine the places that pass through once you enter your home: a big box of cereals on the front door, a carton of milk lying  on the sofa, eggs on the table etc etc. This method helps us to imagine the sequence of places that we pass through every time and recall the things that we associated with those places so that the items can be remembered easily.
Trivia:

• Sherlock Holmes, in the BBC series, Sherlock, uses this technique in the episode 2 of season 2 'The Hounds of Baskerville' to recall events from his memory. 
• The Memory Palace technique is also called the Method of Loci
