What is time?

Here, we are in front of the most perplexing philosophical question of all time. But what does that "of all time" actually mean? Do we suggest that something was happening back there in the past, which is done right now and we can only remember it? Or that it is still present somehow, not only in our minds but in the mysterious interwoven tissue of space-time? Or it is just an expression? Well, one thing is for sure, on that topic we can't really lean on science for a decisive answer. In fact, it is the scientific discourse that brought even more confusion or we can say perspectives to the question. There are many theories and most of them seem to be equally plausible. So what are your personal feeling about it? Do you believe that there is only the present moment or maybe you are eternalist? Here is a short video that will maybe shed a light on that enigmatic issue.

The wisdom of the epic sci-fi fantasy book Dune

1. "The mystery of life isn't a problem to solve, but a reality to experience." - Frank Herbert, 'Dune'.

2. "Deep in the human unconscious is a pervasive need for a logical universe that makes sense. But the real universe is always one step beyond logic."

3. "The concept of progress acts as a protective mechanism to shield us from the terrors of the future."

4. "It's shocking to find how many people do not believe they can learn, and how many more believe learning to be difficult."

On 20th November 1998, the first module of the International Space Station was launched

The module was called Zarya and was Russian-built and American-owned. Zarya is an FGB (Functional Cargo Block), which provided electrical power, storage, propulsion, and guidance to the ISS during the initial stage of assembly. The International Space Station (ISS) is a modular space station in low Earth orbit. It is a multinational collaborative project operated by 5 space agencies – the Canadian Space Agency, the European Space Agency, US's NASA, Russia's Roscosmos, and the Japanese Aerospace Exploration Agency. It is a manned artificial satellite. The brightest man-made object visible to the naked eye from Earth. ISS orbits the Earth at a speed of 17,500 miles per hour (28,000 kilometers per hour) at an average distance of 248 miles (400 kilometers) from Earth.

The station's purpose is to serve as a microgravity and space environment research laboratory where scientific research is conducted in meteorology, astronomy, astrobiology, physics, and other fields. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars.

Recent progress in Climate Models

Climate models are used to predict how the climate will likely respond to rising greenhouse gas concentrations in the coming decades, a timescale crucial to meeting the terms of the Paris Agreement. That's why it's necessary to keep developing and refining such models to better support climate policies.

The 3 ‘demons’ that haunted legendary scientists

The inner demon of the scientists

Jimena Canales, an expert in 19th and 20th-century history of the physical sciences, began a fascinating journey a decade ago. She began to investigate the appearance of the word demon in a historical context. And it turned out that it is present not only in religion or occultism but in the serious world of objective science, skepticism, and technology. Well, first of all, one should take into account that the word comes from Ancient Greek δαίμων daemon with the meaning – spirit or a divine power but not necessarily an evil one or malevolent in any way. The negative connotation came with the tradition of Christianity. Long before that, the daemon notably appears in Plato's works describing the divine inspiration of Socrates. It had (and still has) this positive and even productive meaning, which is the subject matter of this short video by Big Think. So, which is your demon?
