Science and Scientism

Allegory of science
Attributed to Sebastiano Conca

The Dictionary of Oxford Languages defines science as follows:

The systematic study of the structure and behavior of the physical and natural world through observation, experimentation, and the testing of theories against the evidence obtained.

This definition is complete, because it covers the three branches in which scientific knowledge is normally classified: theory (reasoning), observation and experimentation. We could add applied science (technology), which is often classified separately.

On the other hand, scientism is defined thus:

The belief that scientific methods can be applied to all problems, with the consequent application of inappropriate scientific methods in unsuitable circumstances.

Another conversation with ChatGPT

As I said in the previous post, last January I did two sessions with ChatGPT from OpenAI. In the second, my questions were directed to the following scientific topics:

• The special theory of relativity, the limit of the speed of light in a vacuum, and the possibility of traveling in time.

Throughout the session I was asking the following questions:

1. Can a particle travel at a speed greater than light?

Answer: According to the theory of relativity, as first described by Albert Einstein, nothing with mass can travel at the speed of light...

A conversation with ChatGPT

Last January I decided to test the latest hit in Artificial Intelligence, ChatGPT from OpenAI. To do this, I carried out two independent sessions (I don’t know if the program connected them to each other). My questions had to do with the following scientific topics:

• The first session dealt with a series of questions about the general theory of relativity, cosmological theories, and the standard cosmological model.
• The second session dealt with the special theory of relativity, the limit of the speed of light in a vacuum, and the possibility of time travel.

After the first session, my conclusions are the following:

The world of tachyons and science fiction

In previous posts in this blog I have mentioned various procedures often used by the authors of science fiction novels to make interstellar travel almost as simple and brief as today's airplane trips to different points on Earth. One of these procedures consists of disintegrating the ship and reintegrating it into the universe of tachyons: hypothetical particles, compatible with the theory of relativity, that would always travel at speeds greater than the speed of light. Thus it would be possible (in principle) to travel very fast to the point we are interested to go to, reintegrate the ship into the world of tardions (in other words, into our world), and presto! We have traveled faster than the speed of light.

In fact, the authors of these novels (of which I am one) don’t usually go into detail about what the world of tachyons would be like. We simply assume three necessary conditions for interstellar travel to be possible:

The abolition of truth

Aquilino Polaino-Lorente

In his book Antropología e investigación en las ciencias humanas (Anthropology and research in human sciences, 2010), Aquilino Polaino-Lorente writes:

The evangelical phrase "truth will set you free" is being replaced by the opposite: "freedom will set you true." (Chapter 6). After scientific relativism, political absolutism almost always appears... only irrational attitudes remain, dominating the person, the world and politics... The truth is a mere hostage of the material world, without admitting any discussion outside of it. The absence of truth has maddened science. (Chapter 10).

Science has as its objective the search for truth. Its purpose is to discover what happens in the world, outside and inside of us. And once discovered, that truth also should set us free, because it makes technology possible, which increases our freedom (or should increase it).

Nine years of Divulciencia-Populscience

Nine years after the creation of the blog Divulciencia (whose English version is named Populscience), I have published more than 400 posts, which is equivalent to about 45 posts a year (in summer I take vacations and do not publish).

These posts are classified into 25 thematic threads, of which the most visited is What is man?, one of whose posts, Is man just an animal? is the most visited post in the blog, with more than 55,000 visits.

The best sci-fi films

As usual, there are lists of the best movies for all tastes. In this article I will focus on three:

• The 100 best films in history, the result of a vote among seven film critics, organized by the newspaper La Vanguardia in 2007.
• The 100 best films in history, the result of a vote among hundreds of thousands of users of IMDb, the largest database on cinema.
• My personal preferences: the 230 movies I have liked best.
