A comment on Talk: Martin Rees asks: Is this our final century?
Our race is not the issue, it is our brains that are universally selected.
Brain is the ultimate biological complex, and Just by knowing that a neuron employs electricity to function the brain and that the brain creates technology, we have to realize that our brain is up to a very transformative stage in relation to our biological evolution. The evolution of our brain is a universal matter, a transformation that is more relevant to a universal standard.

That change won't be because of what anyone said - it will be because of what that girl heard...

A reply on Talk: Gever Tulley teaches life lessons through tinkering
Sometimes the saying "don't reinvent the wheel" becomes limiting. Imagine if someone did reinvent the wheel!

A comment on Talk: Elizabeth Gilbert on nurturing creativity
part of the book which got me really thinking was when she talked about loneliness and depression finding her in rome. this description and the way i could get into what she was relating was as if i was there with her. it was more than that as well, it was as if i had felt those same feelings and had those same over whelming emotions. i am in awe of the way people are able to write when they can make me feel. also. there was the humor and the visual images which hang with me as i am remembering those pages. it is a treat to read this book. i am starting the "pray' part when she is in india. i have never been to india yet i think i will feel like i have.

A comment on Talk: Arthur Benjamin's formula for changing math education
During university years I had an optional class of Statistics and the only reason I took it was that I needed those extra credits. I didn't like it at all, but now I realize that the main reason for disliking it was the teacher. Other reason was that the classes of Statistics were not related to the real world, to examples of real life. It was not compared to interesting or ordinary situations that can happen every day.
Now, one of my biggest passions is poker and I have to tell you that I really regret those Statistics classes. I can tell you that is one of the most important thing in poker and I'm learning every day more and more. The result is that my game of poker has improved considerably and I teach others to think statistically.
Ups, now I see that only 1000 characters are allowed :)
So, think statistically!

A reply on Talk: Diane Benscoter on how cults rewire the brain
People always assume that religious people are just rule followers. Not so at all. They don't just see a rule in the Bible and slavishly follow it. They live their life acording to a code that they believe makes sense and improves their spiritual life when followed. they know this from experience. It's not 'pie in the sky when you die' it's improved life now.
Religion can never make sense with logic alone. If i show you a food you've never seen before there is no way i can prove to you it's delicious. The only way for you to know is to experience it. You might be swayed to try it by the fact that thousands of other people seem to be happy when they eat it but there is no 'data' or 'proof' that can show it to be great. Eating it is the only way to know. You can always spit it out.

Any idiot knows that everything affects the way our mind functions and the conclusions it makes.
If you use critical thinking then finally, despite testing and double testing, when you can't find a superior idea you take on the best explanation for something that you consider to be logical and reasonable. Even then, you are always open to someone or some idea proving you wrong or its self superior. That's about as open minded and critical as you can get. That's the state of mind of most Unificationists that I know.
Most UC detractors have never looked into UC theory in any depth. They are the ones who lack critical thinking because they draw unshakable conclusions before ever considering all sides. They operate on emotion and feel important and superior to be the denouncers. It's amazing how the more you guys talk/accuse, the more you describe your own mental process. Keep it up

Are these four girls smarter and do they have more critical thinking skills, because with their creative U of Chicago E Math since kindergarten they never developed the most basic number sense? No,through the years of blocks, and rubber bands, and spiral curriculum they never did learn it to mastery. In the burbs the dirty secret in math ed is massive tutoring . In the inner city --social injustice

Gilbert and those she quotes *know* that they are the source of the creativity.

Afterall, not that many high school students actually take calculus. And as a person who just took calculus, I know that it is impossible to pass the course without solid knowledge of algebra.

A reply on Talk: Thomas Barnett draws a new map for peace
Second, I would argue that excessive militarization takes resources away from more economically, culturally and technologically productive investments, weighing the country down enough to allow other powers to catch up enough to challenge US hegemony.
