A principal motif throughout the scientific investigation of movement spanning two thousand years, from Aristotle to the seventeenth century, is the progression and eventual acknowledgment of the inertia principle—a fundamental aspect of classical physics encapsulated in Newton’s First Law. This principle contradicts earlier theories proposed by philosophers such as Aristotle, who contended that an external […]

On August 7, President Donald Trump enacted an executive order requiring a review of federal research grant allocations by political appointees, triggering considerable backlash from the U.S. academic research sector. This order seeks to guarantee that grant funding is in accordance with the administration’s priorities and permits the cancellation of initiatives considered to no longer […]

In a continuous battle against the rising global plastic pollution crisis, UN-led discussions aimed at creating a groundbreaking treaty have once again failed to reach consensus. This latest impasse followed a 10-day meeting in Geneva, prolonging a negotiation effort that has already persisted for more than three years. Initially, negotiators had a deadline set for […]

In 1618, while Isaac Beeckman was elucidating inertia to René Descartes, Johannes Kepler transformed astronomy with his third law of planetary motion, though it initially received minimal recognition. Kepler’s third law illustrates the connection between a planet’s orbital period and the semi-major axis of its orbit: the square of the period is proportional to the […]

Burning a candle infused with various metal precursors can yield carbon soot nanoparticles that encompass as many as 25 different metals. The scientists involved in the study indicated that this technique might present a viable avenue for the advancement of electrocatalysts. Producing high-entropy metal-based nanomaterials typically necessitates extreme conditions, such as elevated pressures and temperatures […]

A group from Humboldt University of Berlin, spearheaded by Michael Kathan, has created an innovative light-driven molecular motor that generates catenanes from hydrocarbon strands independently of templates. This breakthrough addresses a major obstacle in molecular machine design: harnessing directional movement to shape three-dimensional molecular forms. In contrast to conventional approaches that depend on prearranged starting […]

Optics, an essential domain of physics, investigates the characteristics, manipulation, and detection of electromagnetic radiation—mainly light. Its core aspects, including light propagation, reflection, and refraction, have been examined since ancient times. Geometric optics, initiated by the Ancient Greeks such as Euclid, Hero of Alexandria, and Ptolemaeus, primarily concentrated on vision theories. They proposed an extramission […]
