The Cosmic Microwave Background (CMB) is a cornerstone of modern cosmology, providing a snapshot of the universe when it was just 380,000 years old. This ancient light offers a wealth of information about the early universe, its composition, and the fundamental parameters of the Big Bang model. In this article, we explore the significance of the CMB, the key discoveries made through its study, and the ongoing research that continues to refine our understanding of cosmology.

In 1905, sitting in a Swiss Patent office a young patent clerk Albert Einstein unrooted the orthodox thinking of the Physicists who had till then believed that light was a form of electromagnetic radiation. Einstein challenged this assumption, proposing that light was not a continuous wave of energy but consisted of tiny particles or corpuscles.

It might sound odd to anybody who is not from a scientific background that we only know just about less than 5% of the universe. So our understanding of the known universe is minuscule in comparison to what we don’t know. It is estimated that 28% of the universe is dark matter while a whooping 67% is dark energy. But now the question is what are these dark matter or dark energy?

Coral reefs have been dying worldwide because of climate change and the subsequent warming of the oceans. As the ocean temperature rises and water...

This is the first of the GOS series.

I have planned to create a series of blogs celebrating the lives of Great scientists on whose shoulder scientists of today stand. In his letter to Robert Hooke, Newton wrote, "If I have seen further it is by standing on the shoulders of Giants." So, these are the persons we should be grateful to for the giant leaps in the field of science and technology. Instead of my usual way to write long posts on a single topic, I plan to design the blog series Giants of Science into seasons. In the first season, I would discuss a single scientist's works spread over several blog posts accounting for the season.

We have had this idea that dinosaurs are long gone and are extinct, but to tell you the truth they are living among us but in a form we don't associate them with.

The terms warm-blooded and cold-blooded are a bit inconsistent to the actual meaning of these words. Cold-blooded animals are the animals that are incapable of...
