Natural Fractals

These pictures of lightning bolts are clear examples of fractals, each of the small lightning bolts look very similar to the original lightning bolt, they repeat over and over and get smaller everytime they but very similiar to the original, which is one of the basic characteristics of fractals.

This video shows that even though lightning bolts are dangerous natural marvels it doesn't explain the mathematical significance of lightning strikes, and fractals do.

David Reimer

In 1965 David Reimer was born in Canada. When he was 8 months old, he was taken to the hospital to have a circumcision done. Unfortunately, his penis was burned off during this standard procedure due to the fact that the physician used an electrocautery needle instead of a standard scalpel. David's parents went to a psychologist named John Money and he suggested that a sex change was the simplest solution. David's parents agreed without knowing that Dr. Money had other intentions than to help them. He wanted to use David as his private case study to prove that nurture, not nature, determined gender identity. David had a vagina constructed and was given a hormonal treatment, he was now known as Brenda.

This experiment was completely unethical because John Money used David as his own private case study, and told David's parents to change David's sex so he could have a case to research on, he was not profesional at all. He did not tell them that he wanted to do this experiment so he did not have their consent or David's as we was not aware of this at all. He did not take into account all the different problems that this would bring into David's family's life and David's as well. David's mother was suicidal, his father was an alcoholic and his brother was severely depressed. David's parents decided to tell him what had happened when he was 14, and he decided that he wanted his penis to be reconstructed. After many year of struggling with gender identity he committed suicide at age 38.

Perception Post
"Doubt is the key to knowledge" (Persian Proverb)
Perception is how we see things and doubt is a key element in perception. When we see something we don't necessary need to believe it, it depends on how we perceive it that make us believe something immediately or have doubts about it. When we doubt something we have this tendecy to try and get the correct answer and therefore we acquire more knowledge.
1. A cultural example could be that not all cultures believe in God. Some cultures perceive God as a superior being but they don't call it God. Some cultures have doubts about God's existence and they all have different ways and paths to search for this "truth".
2.In school sometimes teachers make mistakes and most of the time they are not corrected and we end up learning something that is not correct. But sometimes some one notices the teacher's mistake and doubts that what he/she said is correct, so he asks and then the correct answer is given and knowledge is acquired thanks to the student's doubt.
3. One time, I was in my math class with Mr. McDowell and he was solving an equation on the board but for some reason I doubted that the answer was correct, something didn't look right. So then I started solving the equation on my own, and I figured what he did wrong and I corrected him. Thanks to my doubt everybody was corrected and acquired the real knowledge, thanks to the way I perceived the problem.
