Listen to classical music.

According to research published in the science journalLearning and Individual Differences, it is -- at least for the purpose of studying.

University researchers from France found that students who listened to one hourlong lecture where classical music was played in the background scored significantly higher on a multiple-choice quiz about the lecture compared to the students who didn't listen to the lecture with music. The researchers speculated that the music put the students into a heightened emotional state which made them more receptive to information.

Although listening to classical music might not turn you into an instant genius per se, it will help you better understand and retain the information you've learned. So, the next time you want to learn a new subject or skill, open up Spotify, find some classical music playlists and start listening.

Eat omega-3 fatty acids.

Boosting your brainpower can be as simple as changing what you eat. Adding more foods that are high in omega-3 fatty acids to your diet is a simple -- and delicious -- hack to make you smarter. Foods that are high in these fatty acids include fish like mackerel and salmon, oysters, caviar and walnuts.

According to Dr. Scott McGinnis, assistant professor in neurology atHarvard Medical School, omega-3 fatty acids perform a number of jobs for our brains, including building cell membranes throughout the body and the brain as well as having anti-inflammatory and antioxidant effects that can promote healthier brain cells and less deterioration of the brain. So, if you want a smarter brain well into old age, adding some fish to your diet may be one of the ways to get there.

Create a "memory palace."

Be like BBC'sSherlockand create your very own "memory palace" (alternately, "mind palace") to improve your memory. Creating a memory palace is a simple technique that dates back to ancient Rome and Greece. The memory palace technique, also known as themethod of loci,是一个方法啊f memory enhancement which, according toWikipedia, "uses visualizations, with the use of spatial memory, familiar information about one's environment, to quickly and efficiently recall information."

It works like this: Create a layout of a building or a town in your mind. Choose a place that's very familiar to you, like a shopping mall you frequent or your childhood home for instance. Visualize a route for your memory palace, so instead of just visualizing a house, you picture how you would walk through it.

Then identify specific locations to store information. You'll store each piece of information you want to remember in a specific location such as the medicine cabinet in the upstairs bathroom, behind a picture frame above the bed and so on. After practicing, the idea is that you'll be able to walk through your memory palace whenever you want and pluck information easily from wherever you've hidden it.
