I am seriously thinking of adopting some cockroaches as pets. I am already choosing their names. The only problem is that I haven’t been able to see their balls to catch which one is male and which one is not. Maybe they are asexual until they come into heat. And only then, a part of their body is transformed into genitals… the intestines or something, because I don’t think they have lungs. Yes, definitely, it must be the intestines, the colon to be more precise. The colon becomes genitals for mating. But I haven’t seen it. I only see asexual…


Being a native Spanish speaker, I am very clear that the decades (and centuries, and millennia) begin in years ending in 1, like 2021. This is because historians do not have a year 0 (zero). The Christian Era, therefore, begins in year one (and the year before that is year one before Christ, or -1).

Consequently, the first decade, the first century, the first millennium, they begin in that first year, number 1. In the long run, this means that all decades, centuries and millennia begin in a year ending in 1. But it seems that speakers of other languages…


Christopher Nolan’s latest film has raised the issue of the different types of time travel that both science and fiction have conceived. What are these four types and why would only one of them be impossible?

It’s not easy to talk about Tenet without falling into a spoiler, which is really a shame because a lot of the appeal of the movie lies precisely in the surprise factor. Unfortunately, the title of this post already represents a spoiler in itself, and what I’m going to develop next aggravates its degree of spoiling. …


Many managers think that formal requirements assessments are unnecessary, that development projects can be accelerated simply by putting pressure on the developers, or that if a small team of programmers cannot complete development in time, it is enough to add more people to the team to speed it up. Here I explain why these myths are false and can also lead to total project failure.

Business administration is usually carried out by very talented people who have known how to position a brand and lead a team, without the need for the theoretical tools of formal training, such as that…


Desolate streets and wild animals walking on them, all because of a virus. This is what we read in the press and it is also what happens in a work of fiction that dates back a quarter of a century.

The pandemic that has caused the coronavirus COVID-19 sometimes seems like the plot of a movie. I have heard it several times from my father, as I have been keeping a preventive quarantine in his house for some days now. …


I found a scientific mistake in one of Philip K. Dick’s novels, “Galactic Pot Healer”. It is so weird because it is the first time I find a severe mistake (not as the ring world debate) in a renown sci-fi author.

Most of us know, at least by name, films like Blade Runner, Minority Report or Total Recall. What these science fiction films have in common — as well as others, not as successful at the box office — is that they are based on stories by Philip Kindred Dick, better known as Philip K. Dick or simply PKD. …


The theory that removed the foundations of physics at the beginning of the 20th century and that has turned out to be the most successful scientific theory in history, making possible the creation of almost all the inventions that make up today’s technology, from lasers to computers and other digital devices … That theory … We still don’t understand it!

The famous physicist Richar Feynmann said after receiving the Nobel Prize for his contributions to quantum mechanics: “If you think you understand quantum mechanics, you don’t understand quantum mechanics”. …


Our ancestors discovered in the world of experience a rational order or “cosmos” that allowed them to understand natural phenomena. Thanks to the scientific paradigm shift of the 20th century, chaos theory was developed. How do cosmos and chaos come along at the light of contemporary science?

Let’s look at the children, let’s see them play. Running from one side to the other, climbing, swinging. When we are girls and boys, the excitement of the novel, the healthily risky, is what most amuses us and attracts our attention. With time, we lose that capacity for astonishment and with it we…


What is Cybernetics, what kind of discipline can be at the origin of the changes that challenge humanity today, changes in the everyday world, in the way we interrelate and communicate, as well as profound changes that have come to affect the way we do science?

When Time magazine conducted a survey to determine the one hundred most influential people of the twentieth century, there were names such as: Einstein, Fleming, Freud, and the Wright brothers, among the most known, and other great scientists and thinkers not so well known to the general public. It is striking that Norbert Wiener’s…


Which came first, the egg or the hen? Does consciousness arise from matter or is it the other way around?

What is the root of all that exists? What is the ultimate principle underpinning the existence of the universe, life and consciousness? For a religious person the answer is very clear: God. But if the universe is self-contained and was not created by an omnipotent or omniscient being, where is the root of existence? In matter or in consciousness?
