Optical vs. Copper Cables: The Road to Terabits and Practical Challenges
Optical and copper interconnection technologies represent two distinct approaches to data transmission, each with its own advantages and limitations. While fiber optics dominate in performance, copper retains its technical and economic justification. Let’s take a deeper look at their characteristics, physical principles, and practical challenges. Ethernet and Data Transmission: From Packets to Errors Ethernet communication…

🌍☢️ THE WORLD AFTER A GAMMA RAY BURST: A Scientific Projection of Cosmic Apocalypse
What would happen if Earth were hit directly by a GRB? A gamma-ray burst (GRB) is one of the most energetic phenomena in the universe. It occurs during the explosion of a massive star or the collision of neutron stars, releasing more energy in seconds than the Sun emits in its entire lifetime. What if…

Cosmic Radiation – From Tesla to Apocalypse 🌌⚡
Tesla and the Discovery of Cosmic Rays 🔍1899 – While experimenting with high-voltage receivers in Colorado, Nikola Tesla detected unknown signals. He assumed they came from the Sun or other stars – the first indication of cosmic radiation. It was later revealed he had registered cosmic rays (which Victor Hess would confirm in 1912). Irony: Hess…
