Science: Neonicotonoids, plants, and bees
I. Introduction: The Toxic Betrayal of Modern AgricultureNeonicotinoids, commonly known as neonics, represent a class of systemic insecticides that have been heralded as a cornerstone of modern agriculture since their introduction in the 1990s. Marketed as a precise, efficient solution to pest control, neonics promised higher crop yields and reduced environmental impact compared to older…

Health: Supernumerary teeth
Supernumerary teeth, often referred to as hyperdontia, are additional teeth that develop beyond the standard set of 32 permanent adult teeth. These extra teeth can appear in various regions of the mouth and may present in diverse shapes and sizes, ranging from fully formed teeth to malformed structures. Hyperdontia is a relatively uncommon dental anomaly,…

Geo: The Peeling Earth
The “Peeling Earth” is a evocative metaphor for the ceaseless geological processes that sculpt Earth’s surface, with mountain ranges standing as the most dramatic expressions of this dynamic interplay. The term “peeling” captures the dual forces of tectonic uplift, which thrusts layers of the Earth’s crust skyward, and erosion, which relentlessly strips away these layers,…

Physics: Flat Universe
The concept of a “flat universe” is a pivotal idea in modern cosmology, emerging from the interplay between Einstein’s theory of general relativity and the Friedmann–Lemaître–Robertson–Walker (FLRW) metric. General relativity, proposed by Albert Einstein in 1915, revolutionized our understanding of gravity by describing it as the curvature of spacetime caused by mass and energy. The…

Physics: Varying Speed of Light
The speed of light in a vacuum, precisely measured at approximately 299,792,458 meters per second, stands as one of the most pivotal and unshakeable constants in the realm of physics. This value, often rounded to 300,000 kilometers per second for simplicity, is far more than a mere numerical curiosity—it is a foundational pillar that supports…

Physics: Symmetry
The Profound Role of Symmetry in Physics Symmetry in physics is a profound and unifying concept that has fundamentally shaped our understanding of the universe. At its essence, symmetry refers to the invariance of physical systems under specific transformations—be they spatial shifts, temporal changes, or more abstract internal alterations. This principle, when expressed through the…

Physics: Making the Cosmic Microwave Background and new scientific quests
The Cosmic Microwave Background: Standard Model and Beyond The cosmic microwave background (CMB) is widely regarded as a snapshot of the oldest light in our universe, dating back to the Big Bang approximately 13.8 billion years ago. In the standard cosmological model, the CMB represents the thermal radiation left over from a hot, dense phase…
