Mathematics is not so useful in practice as you might think

Mathematics is an useful model for reality. However, most inventions that claims that use mathematics are only inspired by mathematics. Sometimes the mathematics was created after the fact. Encryption is 100% based on mathematics, most of the other technologies can be imagined without advanced mathematics - while arithmetic is always useful. Logic is just a tiny bit of mathematics that governs the binary gates used in computers. But nobody makes a complicated integral to decide how tight the electronical gates can be placed - this is based on experiments AFAIK. We still rely on trial and error for most of our inventions. And this is for a good reason, mathematics cannot provide the answer except for models that we already derived from experience. There are many non-linearities in real life that cannot be derived mathematically - take for example the friction of a body with air on very high speed. AFAIK we cannot mathematically calculate the portance of a certain airplane wing except by...

How to fight deflation

It is said that money value results from the quantity of money that are chasing the products. It is actually the opposite: money value depends on the rate of products chasing money. It sounds similar, but it is not the same. Let's take it slowly. The value of the money depends on the products that can be bought with a monetary unit. That value depends on the product price. The seller will always try to maximize its profit, so we will try to sell each product with the highest possible price. Higher price is an inflationary pression: one unit of money will buy less products. What opposes to the inflationary pression from the sellers? One limitation is the share of wallet that the consumer affords to allocate for that product. If a product is too expensive, potential customer might delay of give up buying that product. This creates a problem for the producer. But let's see closer why. The pressure for the producer to sell cheaper - in order to sell something - comes from its debt....

A secular God concept

All that is good In a first approximation, God is a catch-all concept about everything that is unexplained about the world and human life. Such God concept is consistent with most religious beliefs that I know. Most modern religions that contain some kind of "Evil" concept will associate God mainly with things that are good for humans. Here we will use this conceptual dichotomy between God and Evil. The mystery A God that contains all the unexplained features that are favorable to humans is inherently mysterious, even by the above definition. Why life exists rather than not? How that human life exists?

On Knowledge and beliefs

We consider many propositions about the world as either true or not true.  However, in my view, human knowledge is not a collection of true and false propositions. What we consider as evidently true are only propositions about the world that we believe to have a very small probability to be false. The above is still compatible with an objective Reality, however most of our knowledge about Reality is highly mediated, so that we can rarely be fully certain about something. Mount Everest I "know" that the highest mountain in the world is Everest (from the sea level). However, I never seen that mountain. Even if I could visit and measure mount Everest, it is not realistic for me to check all the other mountains in the world to verify that there is no higher mountain somewhere. Think Popper. I only believe that Everest is the highest mountain in the world because a lot of sources tells me this (externalism). It is unlikely that any of my sources verified personally that there is n...

On Russel's Paradox

Russel's paradox is defining "the set of all sets that don't contain themselves". You can show that such construct leads to a contradiction. Read the wiki link for details. I started this article as answer to this article . There is another interesting paradox discussed by Bertrand Russell: "The smallest positive integer not definable in under sixty letters", actually better known as Berry's paradox  You can also prove that such number creates a contradiction, because you just defined it under sixty letters. For me, the above paradox shows that it is not enough to create a condition for something to exist with that condition - or a set of such elements. Such paradoxes argue that such objects defined by a predicate cannot exist sometimes.
