Religion is a useful model

"All models are wrong Some of them are useful" ( aphorism  in  statistics ) Belief is in your deeds Let's observe first that we can never contain the whole complexity of the world in our brain. In most situations, we often use fuzzy heuristics to take decisions. For example, when a child makes a small mistake, you can never know if it's best for his future to punish him or to forgive him. The punishment might teach him to not do it again. The forgiveness might teach him to forgive and would protect his self esteem. We usually use our intuition and just hope it does not matter so much if we are wrong. We have stronger guidelines for more serious situations. "You shall not murder" is widely accepted as a strong rule in both religious and secular societies. However, there are exceptions to this rule, for example it's usually acceptable to kill someone to prevent more harm - like other killings. The only way to assess someone's adherence to a certain bel...

On Philosophy - essay

  One philosopher said that "philosophy is a natural act of human living" and I agree with him. But what brings philosophy in addition to "regular" science"? I find Philosophy to be a kind of "meta-science", permanently inquiring about the root of all assumptions that we use. In this way, Philosophy is different than "regular" science, however it can contributes to the methods used in all the rest of the science. By analyzing the limits of our knowledge, we can better understand what level of certainty we can expect from science and the rest of our knowledge and believes. Of course, by using specific methods and logical deduction in assuring coherency, Philosophy is also a science in itself.

Debt gives value to money

What gives value to money? There was a time when money was pure gold. Later, money was a certificate that you own a quantity of gold in bank (banknotes). Now the money are just quality paper, without any deposit behind. How that it has any value? Some said that money is just a convention, and the fact that the state accepts that coin as the "legal tender" gives it value. However, we know many coins that lost theirs value despite the state effort to  sustain it. How that other coins survives? I claim that debt is the one that gives value to the today's (fiat) money.

DNA and the fabric of the Universe

The genetic code seems to not be enough to describe the complexity of a human being . In fact, it seems too small to describe most of the life forms. We could assume that the genetic code has all the information very compressed, but still... I will approach the problem of describing life complexity based of information theory.

Genetic code (DNA) is not enough

Photo: wikipedia.org Genetic code (DNA) could be seen as the best compression algorithm that we have ever seen . Just think about it: in only around 1 GBytes, DNA could store the information to create a human being, with all the general and specific characteristics and many non-educated behaviors. In 1 GBytes, the current technology could barely store a 1.5 hour movie at rather low quality, but human DNA is able to encode everything that is human in a lifetime.

The meaning of music

The meaning of music is hard to capture in words. Let's try some ideas anyway! The brain bug The brain has a natural ability to extract patterns from all the stimulus. It's a fact that we like the music that has some patterns: that is not very monotonic (boring) but not very random either, so we can continuously learn some new patterns. Somehow the brain has the illusion that it continuously learns in an accelerated rate by listening music. So music could be considered a small addiction at the first analysis.
