Great Way To Learn:Test Yourself!

Fascinating article from Scientific American on one awesome way to learn and retain new information. It revolves around answering questions about the subject first before diving into the material...

Creation, Causality, and The 2nd Law of Thermodynamics

"Science without religion is lame, religion without science is blind."
Albert Einstein

Started thinking about the 2nd Law of Thermodynamics which is basically the law of Entropy. A working definition of this 2nd Law and essentially entropy is that something left to it's own devices will move towards disorder.

For instance, ice cream melts, things get dirty, iron rusts, apples oxidize...

Another example would be, from wikipedia, that states the following, "the second law implies that heat does not spontaneously flow from a cold material to a hot material, but it allows heat to flow from a hot material to a cold material. Roughly speaking, the second law says that in an isolated system, concentrated energy disperses over time, and consequently less concentrated energy is available to do useful work.

So from a creation standpoint and from a person who believes in The Carpenter of Creation, a Creator God, how could the universe be created from random chance?

In the context of entropy and the second law of thermodynamics, how could order, the order and detail of the universe, be created from disorder. The only way ice cream can be frozen again is for some outside force, be it a human, to act upon it...namely placing it back into the freezer. In order for the stability and complexity of the universe to be created and remain in existence is to have The One and Only Creator God.

Whether you believe in The Creator God or not, you still have to come up with some explanation on causality...what caused the creation of the oxygen we breath, our hearts to beat, our minds that think, the grass that grows, the seasons that change? Actually, believing in some other way to explain the creation and existence of life, takes more faith than believing in God...

As a future doctor, God-Willing, I will use science, not avoid science, to strengthen my beliefs that, "In the beginning God created the heavens and the earth." Genesis 1.1

The Three Brains

In his book, Study Smarter, Not Harder, Kevin Paul talks about "The Three Brains" other wise known as the "Triune Brain," and how they apply to learning. Very Interesting. Here is the nutshell:

Lower Brain: aka Mammalian Brain
Responds to stress, reacts to 'fight or flight.'
This response wants to block out our higher thought processes and operate on 'instinct' mode during times of stress. Thus it is necessary to "quiet" the mammalian brain during studies, test-taking, performing surgeries, taking a penalty kick, or any other highly intense situation where we need to stay calm, cool, and collected in order to think brilliantly. One way to train the ability to stay cool under pressure is to train under pressure.

In an article from Scientific American Mind, RaƓul R. D. Oudejans, a psychologist at Free University Amsterdam, "The best way to make a performance situation feel like rehearsal, is to subject yourself to the same anxiety-packed conditions during practice that you expect to encounter during your moment in the spotlight"...he goes on to say:

These results indicate that turning up the heat from the very first day of practice may be one of the most effective ways to immunize yourself against blowing it. “Performers train and train, but it’s not that common to specifically train under these kinds of psychological constraints,” Oudejans says. “They’re trained in how to play their game, but they don’t train under pressure, so they fail.” Training in such situations minimizes the possibility of freezing up for the same reason that letting spiders crawl all over you makes them less frightening: your brain gradually adapts, so that circumstances that once would have made you uneasy no longer feel novel or threatening. “The more exposure you get to these high-pressure situations, and the more you succeed [despite them], the less likely you’re going to get that whole affective experience,” explains Art Markman, a psychologist at the University of Texas at Austin. In other words, the more comfortable you feel, the less likely you are to be affected by pressure.

Middle Brain: aka Limbic Brain
Responds to emotions, long term memory.
Studying, learning with strong emotions attached will increase our long term memory.

Higher Brain: aka Cortical Brain (Neocortex:cerebral cortex)
Responsible for our high level thinking. The mind must be "quiet" and in a state of relaxed intensity in order to think at such high levels. Listening to Baroque music composed at 60 beats per minute is a great way to induce "the zone" and relaxed intensity due to the stimulation of the alpha waves of the brain (which are active during times of relaxed intensity).

I'm going to go and turn on some baroque music now and activate my cerbral cortex!

Cognitive Horsepower

Really cool study in the February/March 2009 issue of Scientific American Mind about Cognitive Horsepower. Here is the short version:

In theory, "stress uses up the same cognitive horsepower that would typically be devoted to mental tasks, scuttling the performance of capable people who depend on their superior abilities," says Sian L. Beilock, psychologist at the University of Chicago.

"When you've got high levels of working memory, you actually use cognitive horsepower to do tasks,...and when you worry or stress during a test, then that stress is competing for the same resources as you are using to think at high levels and great speeds.

So if If you find yourself stressing during a test or another high level thinking activity, and your thinking, 'Crap,' then that worry is definitely a problem because it is competing for the same resources as your working memory.

Bottom Line: Stressing and worry want to use the same space and resources as high level thinking and problem solving. Don't let them compete. Quiet the mind so that you can think and ace all tests and other activities with a clear mind!

The solution: Do a "Real-Time Simulation." Rehearse in a situation similar to the performance scenario. Take timed tests, practice sports in extremely high pressured and intense environment, visualize, etc, so that when the heat is on during the real event, it will be like second nature to you and you will perform and excel at peak levels!

Genius

Three thoughts on being and becoming a Genius:

1. Make the complex simple
2. Learn from the success of others
3. Learn from the mistakes of others
