Across an arid lakebed in one of the hottest zones on the planet, hefty stones leave elongated trails in the mud as if they have journeyed under their own motion. Some pathways stretch straight for hundreds of metres, while others curve, intersect, or halt suddenly. For numerous decades, scientists could examine the traces left behind […]

In the earlier episode, I delved into what is conventionally recognized as Euclid’s demonstration that no largest prime number exists. This proof, a refined instance of reductio ad absurdum, evidences the error in presuming a maximal prime. It is a notion I have frequently come across, viewed as Euclid’s own proof of the boundless essence […]

for most concrete, seawater poses a significant threat. Salt invades the pores, causing chemical reactions that disrupt the cement paste, and chlorides can infiltrate the steel reinforcement, leading to corrosion that expands and fractures the surrounding material. However, samples extracted from ancient Roman breakwaters present a markedly different narrative. In the correct Roman formulation, exposure […]

The foremost oxygen generators on our planet are not towering trees. They are microscopic cells in the illuminated layer of the ocean, many of which are too tiny to perceive without a microscope. Collectively, marine plankton are responsible for approximately half of the oxygen produced through photosynthesis worldwide. This well-known estimate requires one crucial clarification. […]

Driven by the constraints of recycling in South Korea, scientists have crafted a technique to generate hydrogen from plastic waste that significantly lowers carbon dioxide emissions. This breakthrough, spearheaded by Woo-Jae Kim from Ewha Womans University, incorporates a pretreatment phase that reduces both energy consumption and emissions. The method works efficiently even with mixed plastic […]
