General relativity is classical in nature while quantum mechanics upholds the idea of quantization and interference at the subatomic scale. Quantum (field) theory successfully accommodates all the interactions of nature in its framework but gravity (this framework is called the Standard Model of Particle Physics). However, general relativity is the only available tool to study all the manifestations of the gravitational field.
Carbon is the basic element of life, but it may soon become the basic element of the rest of the world as well. Graphite, the stable thermodynamic state of carbon under environmental conditions, has been studied and used by humankind for centuries. A single layer of graphite is called graphene and has a thickness of a billionth of a meter.
Mankind is always curious to know how everything started. One of the branches of science dedicated to answering this question is particle physics — the study of really tiny pieces of things i.e. particles. These particles are the really small pieces that build up the world around us and are best described in the language […]
Physicists like to group concepts, but sometimes the theories don’t always get along. Nature’s laws can be currently explained by either general relativity or quantum physics. However, concepts from one group don’t necessarily agree with concepts from the other. Physicists have been trying to find the theory of everything for decades: a single or set […]
Nineteenth century was the century of science evolution. Many revolutionary ideas were presented during this century. In biology, Charles Darwin introduced the idea of evolution and natural selection. The germ theory of diseases was proved. In physics, the experiments, theories and discoveries of the likes of Michael Faraday, Andre-Marie Ampere, James Clerk Maxwell, and others […]
The invention of computer made calculations very fast. It paved the way for a rapid progress in science and technology. The early versions of computer were bulky. However, the invention of integrated chip in 1959 made desktops and laptops possible. For daily life needs, today’s computer technology is good enough. But with the time, data […]
Dr Pervez Amirali Hoodbhoy is a nuclear physicist, mathematician, and activist. He did his BSc in mathematics and electrical engineering from MIT and went on to have an MSc in Solid State Physics and a PhD in Nuclear Physics from the same institution. He has had an extensive academic career: working as a guest scientist […]
Nanotechnology is the science of the extremely tiny. It is the art and science of manipulating matter at the nanoscale. It is a field of research and innovation concerned with building materials and devices on the scale of atoms and molecules. The study of nanotechnology enables us to understand why matter behaves the way it […]
