In the quantum world, processes can be separated into two distinct classes. One class, that of the so-called “perturbative” phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation. Examples are plentiful: the light that atoms emit, the energy that solar cells produce, the states of qubits in a quantum … Read more
The periodic table is a tabular arrangement of chemical elements, organized by their atomic number, electron configuration, and recurring chemical properties. It provides a systematic way to categorize and understand the behavior of elements based on their shared characteristics. Dmitri Mendeleev is credited with developing the first periodic table in 1869, arranging elements by their … Read more
Archaeologists differentiate between different periods of human prehistory through a combination of chronological dating methods, material culture analysis, stratigraphy, and interdisciplinary research. Human prehistory encompasses vast spans of time, ranging from the emergence of our earliest ancestors millions of years ago to the advent of written records around 5,000 years ago. During this long and … Read more
Carbon dating, also known as radiocarbon dating, is a revolutionary scientific technique that has transformed the field of archaeology by providing researchers with a powerful tool for dating organic materials and determining the chronology of archaeological sites and artifacts. Since its development in the 1940s by Willard Libby and his colleagues, carbon dating has become … Read more
Nuclear power is considered one of the ways to reduce dependence on fossil fuels, but how to deal with nuclear waste products is among the issues surrounding it. Radioactive waste products can be turned into more stable elements, but this process is not yet viable at scale. New research led by physicists from the University … Read more
