Why are there 24 hours in a day and 60 minutes in an hour?
Why do we use the decimal number system (base 10)? Today, the decimal number system (base 10) is accepted as the global standard due to its ease of counting with the fingers. However, in the past, ancient civilizations used different number systems such as base 12 and base 60 for mathematical calculations and time measurement. […]
How Do Rockets Launch Into Space and How Do Satellites Stay in Orbit?
Humanity’s incredible progress in aerospace engineering has made it possible to launch satellites and spacecraft into space with increasing precision. But how exactly do rockets work? Why do they require so much fuel? And how do satellites stay in orbit around Earth? In this article, we’ll explore the science behind rocket launches, propulsion systems, and […]

The Future of Lab-Grown Meat: A Sustainable Solution for Global Food Challenges
In many science fiction movies, the problem of providing food for the future and for Earth’s ever-growing population is often addressed by turning to various types of insects. However, there is another more appetizing option emerging: lab-grown meat. Those who have tasted lab-grown meat report that its smell, taste, and texture are very close to […]
Understanding Sunspots and Solar Activity
Occasionally, the surface of the Sun exhibits dark spots, known as sunspots. These areas are covered by magnetic fields and appear darker than the surrounding regions because they are cooler. Sunspots are part of an 11-year solar cycle, with the highest number of sunspots occurring during the solar maximum. During this phase, there are many […]
The moon gets farther away every year
The Moon exerts a gravitational pull on Earth, causing our planet to become slightly egg-shaped. This phenomenon has a significant impact on Earth’s water, more so than other factors, as it creates tides. These tides cause the oceans to pile up on one side of the planet, forming a “tidal bulge.” As the Moon orbits […]
What is the Metaverse? The Future of Virtual Worlds
The term “metaverse” was first introduced in the 1992 novel Snow Crash by Neal Stephenson. In the book, the author used the term to describe a virtual reality where the protagonist interacts as an avatar, engaging in social interactions, shopping, and even defeating real-life enemies. The word “meta” comes from the Greek meaning “beyond,” while […]
Neuralink: The brain-computer interface that will change the world
Neuralink chipsets, one of the most advanced technologies of the 21st century, are designed as a brain-computer interface (BCI) that can be implanted in the human brain. This revolutionary technology, developed by Elon Musk and his team, is primarily intended to help people who are physically disabled and unable to use their arms and legs. […]
