What happens with cholesterol?

Cholesterol is an essential lipid, used to build the membrane of many of our cells. In addition, various steroids, bile acids and vitamin D are synthesized from cholesterol within the body. High cholesterol increases the chances of suffering from heart attacks and strokes. On the other hand, too low cholesterol is associated with depression that can even lead to suicide.

When someone says: I have had an analysis and it turns out that I have cholesterol, we should answer: If you didn’t have cholesterol, you’d be dead. What you have is high cholesterol.

Is science taught correctly?

According to many evaluations, education at the elementary and secondary levels is faulty. Every year, students arrive at the university knowing less, which makes it necessary to lower the level at the university or use desperate remedies, such as the implementation of level zero courses.

On the other hand, textbook publishers sometimes launch a race. Secondary education is supposed to provide students with general, non-specialized training. However, in some subjects, such as chemistry and biology, students may be made to learn questions or solve problems that should be encountered in college, several years later. It seems a contradiction that they are forced to learn more, but actually get out knowing less.

Inventing worlds

Isaac Newton

Physicists seem to have lost touch with reality. Instead of figuring out how the universe works, they dedicate themselves to designing possible universes, an activity that possibly they find pleasurable, but which doesn't seem very practical. The worst thing is that they often insist that their imaginary universes are real, putting speculations above experimentation and transgressing one of the fundamental principles of the scientific method: theories must adapt to facts, not the other way around.

One of the weak points of modern physics is the difficulty of explaining the passage of time. Since Newton’s theory, but especially with Einstein’s relativity, our physicists have not been able to deal with time. This happens, despite the fact that other conceptions of physics, such as thermodynamics and quantum mechanics, require unidirectional time: quantum superposition and collapse make no sense except with the hypothesis of irreversible time.
