Georges Lemaître - The father of the big bang theory

The theory of the Big Bang was proposed by Georges Lemaitre a Belgian priest. Lemaitre was born in 1894 to devout Roman Catholic parents and at the young age of nine, expressed his wish to become a priest. Georges was a cheerful boy and excelled in mathematics and physics. It is said that there are three main branches in science; mathematics, physics and chemistry and everything else is variations to these three fundamental bases. Chemists answer only to physicists, physicists to mathematicians and mathematicians to God for mathematics is the language of God. Georges was equally devoted to God as to science and this was a rarity, for scientists did not show much patience to religion and religions just a passing interest in science. In July 1914, World War I broke out with Germany invading Belgium and France, Georges and his brother Jacques enrolled in the army and were on the front line fighting the war. Whenever there was a break in fighting and gun firing, Georges would pull out his...

The Standard Model of the universe

Sometime in 1970s, scientists came up with the standard model of the universe, the universe is filled with particles and forces zipping around at the speed of light and colluding together to create a magical universe. We needed a model to explain the working of the universe to make sense of all these forces and particles and laws. For example, imagine a library strewn with reams of pages and to bring order to the library we will collect these pages and make them into books, next we will categorize these books by authors and genre now we have some semblance of order. Similarly, scientists came up with the standard model of the universe which is defined at a high level with about a dozen particles and less than half a dozen forces. We know that the universe works and hence assumptions were made in designing the model. Feed data into the model and you will get the same output behavior as in the universe and everyone was happy. However, the standard model does not consider gravity, dar...

The journey of science

There were many scientists who dedicated their lives to science, and it is not possible to mention all these scientists and instead we will focus on some of them to understand the journey of science and the importance of their discoveries.   Democritus   We now travel back in time to 460 BC to a city called Abdera in Greece to meet our first famous scientist Democritus. Democritus was a truly awesome philosopher of his times, a time when man was gazing at the stars in wonder and trying to make sense of the fickleness of nature in terms of floods, droughts, and sickness which they attributed to the anger of different gods, when superstition and witchcraft was rampant, and here was a man who derived the atom!!  At that time there were no measurements or instruments, they were philosophers who discussed, debated and argued their theories with other philosophers most probably till the beer ran out or someone invoked the hand of God to get out of the situation which is probabl...

Aristotle

Imagine living in 380 BC when science and philosophy flourished in Ancient Greece, shaped by great thinkers such as Plato, Pythagoras, and Aristotle . Greek society was built around city-states, agriculture was a thriving industry, and slavery was common. The daily life of the people varied greatly—while the wealthy enjoyed wheat bread, fine clothing, and education, the lower classes survived on barley bread and vegetables. The Greeks worshiped multiple gods, believing that deities lived like humans, experiencing emotions such as jealousy and anger, and requiring sacrifices for favor.   Science, at the time, was the pursuit of the elite. Physicians, philosophers, and scholars were highly valued by rulers, and Aristotle was among the most influential figures in shaping both science and Western thought . His ideas on the geocentric model —the belief that the Earth was at the center of the universe—were widely accepted and later reinforced by the medieval Catholic Church . Because Ari...

Copernicus and Galileo

Religion is based on faith and trust. When Jesus told the fishermen , “Why are you wasting your time fishing for fish? Come with me, and I will teach you how to fish for men,” they immediately left everything and followed him. This act exemplifies faith—believing without questioning. Science, on the other hand, operates in the opposite manner. It is built on skepticism, facts, and constant inquiry. Scientists doubt everything; when a new theory is proposed, it is easier to disprove than to prove. This process of rigorous scrutiny has been crucial to scientific progress—every wrong turn represents lost time and resources, so theories must be tested and refined.   One of the pivotal moments in this conflict between faith and reason was when Nicolaus Copernicus questioned the long-accepted geocentric model of the universe. Aristotle and Ptolemy had established the belief that the Earth was the center of the universe, a view upheld by the Catholic Church. But Copernicus, troubled b...
