Here I present my experience on our visit to the Mica and Quartz mines of Damsila Resources (Pvt.) Ltd. on the 24th of September. At ...
Astrophotography is a sub-discipline of scientific photography and amateur astronomy. And it is a very well-beloved photographic genre as well. Astrophotography is all about capturing astronomical objects such as planets, moons & nebulas, celestial events such as eclipses, propositions, and some areas in the sky. This has been an extraordinary hobby and a field of photography for both astronomy and ...

Sveriges Riksbank is the central bank of Sweden and the prize was established in commemoration of the bank’s 300th anniversary. The task of awarding the Nobel Prize for Economic Sciences has been entrusted to the ...
In quantum mechanics, particles are described by their “quantum states”, mathematical objects that describe the probabilities of observing different results after measurements on them. Quantum entanglement is the effect where the individual quantum state of each particle in a certain pair is indefinite until measured, and the act of measuring one determines the result of the other, regardless of how ...
The Nobel Prize in Chemistry for the year 2022 is shared among three prominent chemists; K. Barry Sharpless, Morten P. Meldal, and Carolyn R. Bertozzi, for laying the foundation and the development of ‘click chemistry’ and ‘bioorthagonal chemistry’. K. Barry Sharpless along with his colleagues Hartmuth C. Kolb and M. G. Finn summarized the concept of ‘click chemistry’ in the ...
The origin of Homo sapiens and the evolutionary processes that led them to present-day beings has always been a topic of intrigue and controversy.

Depression, Anxiety Disorders, Schizophrenia, OCD and Eating Disorders are ...
To whom it may concern, This day, four years ago, was one of the happiest days of my life. It was the pinnacle of my career as a scientist. After millions of rejections, the Science Academy finally decided to accept my project proposal, but under one condition. Should the project head, in this case me, may appear to be emotionally ...
