This is an excerpt from a book named “Essentialism” by Greg McKeown. If we become overwhelmed by our tasks, then we lose our ability to make choices for ourselves. Do you tend to say “I have to” rather than “I choose to”? If so, then you are following the non-essential path. So many of us ...

This isn’t an aesthetic phase and it’s not me trying to be different. It’s a stable reaction I’ve had for years. Oval shapes, pink colors, shiny surfaces — and sweet perfumes — all trigger the same feeling in me: irritation. Not hatred. Not fear. Just a persistent sense that something doesn’t belong. Ovals Feel Structurally ...

Slower perception of time brings you closer to a state where time feels nearly zero. Experiencing such a state would be ideal for evaluating things objectively, as if you were purely an observer rather than an actor. Different creatures sense time in different ways, and this profoundly affects their vision, hearing, and other sensory perceptions.

“A person who hesitates to make a choice will end up with a choice made by circumstances.” Hunter Thompson

Sonsuz gücün özünün tətbiq obyektinə ehtiyacı olduğu üçün onu mütləq güc hesab etmək yanlışdır.

People do not really want freedom, because freedom involves responsibility, and most people are frightened of responsibility. They prefer to live under someone else’s idea of truth, to obey rather than think, to blame rather than act. The real battle is not between good and evil, but between cowardice and courage — between those who ...

Have you ever wondered why a bottle of water costs less than a cup of coffee, even though water is essential for life?

The Koch curve is one of the earliest and most famous examples of a fractal—a shape that displays self-similarity, meaning it looks similar at any level of magnification. It was first described by Swedish mathematician Helge von Koch in 1904 as a curve that is continuous but nowhere differentiable. How the Koch Curve Is Constructed ...

When scientists talk about chaos, they mean systems that follow precise rules but behave in a way that looks unpredictable. A beautiful and common pathway from simple order to chaotic behavior is the period-doubling route to chaos. Below is a concise, easy-to-follow explanation with the key equations written in LaTeX (display math) so you can ...

Theseus was the great hero of Athens — the man who slew the Minotaur in Crete and freed his people from a cruel tribute. When he returned home in triumph, the Athenians preserved his ship as a symbol of courage and unity. For centuries, the vessel was carefully maintained: whenever a plank decayed, it was ...

Have you ever wondered how complex behaviors in nature, like population growth, can emerge from surprisingly simple rules? Enter the Logistic Map, a mathematical model that’s a cornerstone in the study of chaos theory and complex systems. It’s defined by the recursive equation:     Here, is the growth rate, and represents the population (or ...

“We may regard the present state of the universe as the effect of its past and the cause of its future. An intellect which at a certain moment would know all forces that set nature in motion, and all positions of all items of which nature is composed, if this intellect were also vast enough to submit these data to analysis, it would embrace in a single formula the movements of the greatest bodies of the universe and those of the tiniest atom; for such an intellect nothing would be uncertain and the future just like the past would be present before its eyes.”

Ever notice how calm and refreshed you feel after a walk in the forest? That’s partly thanks to phytoncides—natural compounds released by trees. These invisible plant chemicals protect trees from germs and pests, but they also work wonders on us. Breathing them in lowers stress, boosts immunity, and even improves sleep. Next time you need a reset, head to the woods—your body and mind will thank you.

Did you know that parts of your cells were once free-living bacteria? Mitochondria in Humans and Animals Every human and animal cell contains mitochondria (except red blood cells). These tiny powerhouses generate ATP, the cell’s main energy source. But originally, mitochondria were free-living bacteria that entered a host cell about 1.5–2 billion years ago. Over ...
