The ‘Doughnut’ Beam Technique: A New Way to See Incredibly Small Objects
In a recent publication in Optica, scientists at the University of Colorado Boulder have harnessed the power of doughnut-shaped light beams to capture intricate images of objects that are too minuscule to be observed through conventional microscopy techniques.
A Mega Black-Hole Collision and Its Aftermath: Gravitational Waves and the Long-Sought ‘Ringing’
Scientists uncover telltale aftershocks from a significant cosmic merger concealed within data collected in 2019 by the LIGO and Virgo detectors.
Quantum Information Scrambling in Open Systems: A General Description
In the past few years, physicists have been delving into a deeper comprehension of the spread of quantum information in systems of interacting particles, commonly known as "Scrambling." Scrambling is particularly notable in closed systems, which are physical systems capable of exchanging energy only with degrees of freedom within the system. This phenomenon stands out as a characteristic feature of the chaotic dynamics observed in many-body quantum systems.
Measuring the Speed of Light
The measurement of the speed of light, a fundamental constant in physics, began with Ole Rømer in the 17th century, who used observations of Jupiter's moons. Later, in the 19th century, Fizeau and Michelson devised more refined techniques involving mirrors and rapidly rotating gears. Eventually, in 1973, the definition of the meter was based on the speed of light, leading to the highly accurate value we use today: approximately 299,792,458 meters per second.
Aristotle
Aristotle is an Ancient Greek philosopher and scientist. He is a respectable figure in the history of philosophy and has worked in many fields. According to him, natural philosophy is the most important for philosophers. In addition to natural sciences such as physics, chemistry, biology, zoology (Animal science), botany (Plant science), psychology, political science, ethics; logic, metaphysics; history, literary knowledge, and rhetoric, he was interested in social fields such as.
