A Martin Gardner
Recently I just learned of this terrible death. On May 22, 2010 died Martin Gardner, one of the greatest science communicators. He left us but has left a large footprint and the world of mathematics. More »

Who dares to teach, not have to stop learning.
"Who dares to teach, must never Cease to Learn."
(John Cotton Dana).
Every second of life is a moment
"Every second of life is a new and unique moment in the universe, a moment that will never be repeated.
What we teach our children? We teach that two plus two equals four and that Paris is the capital of France.
When will we also teach them what they are?
We should say to every one of them: Do you know who you are? You're a wonder. You are unique. In all the years that have passed, there has never been another child like you. Your legs, your arms, your fingers, the way you move. Perhaps you become a Shakespeare, a Michelangelo, or Beethoven. You have the ability to do anything. If you are a marvel.
You must work, we must all work to make the world worthy of its children. "

2010 in many forms
Not that I have forgotten the blog, what happens is that I had some outstanding things to do. I finished college and now I'm going to be a BA in Education and Humanities, specializing in mathematics and physics, does not sound bad.
Well, in the first article of the year I will find something very interesting that tweeting, write 2010 with only the numbers 1 through 9 using the basic operations:
2010 = 1 +2- (3-4-5) * 6 * 7 * 8-9 2010 = 1 - (2 + (3-4-5) * 6 * 7) * 8 +9 2010 = 1 +2 + (3 +4 * (5 +6 * 7 +8)) * 9 2010 = 1 +2 * (3 * 4 * (5 +6) -7) * 8 +9 2010 = 1 * 2 * 3 * (4 * (5 * 6 +7 * 8) -9) 2010 = 1 +2 + (3 +4 * (5-6 +7 * 8)) * 9 2010 = (1-2-3 +4 * (5 / 6 +7 * 8)) * 9 2010 = (1 +2 +3 * 4) * (5-6 + (7 +8) * 9) 2010 = 1 +2 + ((3 * (4 +5) +6) * 7-8) * 9 2010 = (1 +2 +3) * (4 * (5 * 6 +7 * 8) -9) 2010 = 1 +2 +3 * (4 * (5 +6) * (7 +8) +9) 2010 = (1 * 2 / 3) * ((4 +5) * 6 * 7 * 8-9) 2010 = (1-2-3) * ((4 +5) / 6-7 * 8 * 9) 2010 = (1 * 2 + (3-4 * (5/6-7)) * 8) * 9 2010 = 1 * (2 + (3-4 * (5/6-7)) * 8) * 9 2010 = (1 +2 * (3 +4)) * (5-6 + (7 +8) * 9)
The first database of the world
Throughout history, societies have been concerned with recording historical facts, financial records or tell their property. Thus we can see that in ancient societies developed simple systems such as registration quipu, you might say that is the first form of systematization of a set of data, ie a database .
Change the world
Do not ever doubt the ability of just a group of concerned citizens and committed to change the world. In fact, it has always been the case.

Immigrants digital natives
After reading the article that Mark Prensky wrote some years ago on Digital Natives and Digital Immigrants ( Digital Natives, Digital Immigrants ) I started to think about it.
The digital natives are those who have been born when it was new technology and who have grown using television, computers, cell phones, internet, etc and digital immigrants, people who were not born with those privileges and learned to use these technologies over time.
There are substantial differences between groups either neurological and interaction with their environment, as Mark Prensky describes it, but do not think this should be a generational difference, if we see reality and differences between our countries could add a further categorization, immigrants digital natives.
In Peru there are still places where there is no electricity, phone service and even worse, no computers or internet. The youth of these places can not have spent 5000 hours reading books because they have not read even worse, could not have spent 10 000 hours playing video games because they do not know, even it could be 20 000 hours watching television because they have no TV and the only way to have fun would be the care of the cattle they have, if they have it.
There are still people worldwide who lack access to new technologies and one way or another have to adapt to rapid change that is occurring in our society and lessen the digital divide , despite the efforts of some institutions or programs like OLPC , is resistant to change.
Where we consider these digital natives who have no access to these new technologies, they also have to come to learn to use technology to their advantage, we could not call or digital natives and digital immigrants or who do not have the characteristics of any of them, digital natives but immigrants would be the best description of them.
