Brain Teasers

  • Only 10% of Your Brain
    on 19/08/2019 at 12:00 am

    It is a myth that humans only use a fraction of their brains. Even though scientists are still trying to unravel the mysteries of the human mind, every part of the brain is known to have a function. From an evolutionary point of view, larger brains would not have developed if there had not been an advantage to do so. The origins of this myth are unknown, but it might have originated from a researcher named Karl Spencer Lashley who lived about a hundred years ago. He removed parts of the brains of rats and showed that they could still perform certain tests. The problem with these results are that the rats were only tested on tasks that required the parts of the brain that had not been removed. If the rats had been given other tests, they would have certainly failed. More Memory Articles... […]

  • Left vs Right Brain Thinking
    on 19/08/2019 at 12:00 am

    As we know, the two hemispheres of the brain think in different ways. The left brain tends to be logical and analytical, while the right brain tends to be more creative and spontaneous. When you are using one side of your brain more than the other, this is called left or right brained thinking. Both types of thinking are valuable, so one should try to develop their skills in both. Unfortunately, left brained thinking is the type that is most valued by our society and taught in our schools. Almost all of the major subjects taught in school (math, science, history, etc) depend predominately on left brained thinking. Rarely do teachers encourage their students to think creatively and explore alternate solutions, and rarely are right brained studies (art, design, music, etc) encouraged. This over emphasis becomes even more problematic as students move into the professional world. In order to get support for a new project or idea, it must be clearly defined and understood (left brained thinking) by the people who are going to be paying for it. It's very difficult to get funding for a project if the goals are not clearly understood. As a result, creative ideas don't happen as frequently as they could if right brained thinking was more valued. It's no coincidence that the really creative ideas that occur from time to time are usually self-funded by the inventor working out of their garage. These are the people who understand the true value of thinking creatively. More Creativity Articles... […]

    As it often happens in life evil warlock imprisoned a wise man. Surprisingly he gave him a chance to save himself if he fulfils one task. There is a round tray on the table which can be turned around freely. There are four coins on the tray placed as corners of a square. Wiseman has his eyes covered so he doesn’t see anything. His task is to turn the coins so that they are all heads up. He is not in easy situation. He may turn some coins and than the warlock will turn the tray around. He turns some coins again warlock turns the tray again. It goes on until all coins are turned correctly. At that moment evil warlock ends the game. Wiseman can’t recognize one side from the other by touching it. He has to leave the coins where they were in the corners of a square.
