Sir Isaac Newton – One of the greatest scientists ever

Sir Isaac Newton was one of the greatest scientists of all times. One of his major achievements was the law of gravity. Today’s post is dedicated to Sir Isaac Newton and his achievements.

Sir Isaac Newton

Name: Sir Isaac Newton

Born: 25th December 1642 in Lincolnshire, England

Died: 20th March 1727 in Middlesex, England

Major Fields:

  • Mathematics
  • Physics
  • Astronomy

Major Achievements:

  • Universal gravitation
  • Newton’s method

Isaac Newton was born on 25th December, 1642 and by then his father had already died a few months earlier. Thus he was raised by his mother and his step father. But his later life has been known for many scientific discoveries that have been used in modern day designs, discoveries, scientific researches and developments. In school he had been noted for his despising the curriculum in use because, to him, it lacked the real substance scientific analysis requires. Interestingly, when he later got his masters degree and was able to offer lectures at the university, his lectures have been described as having been too difficult for his students.

The works of Isaac Newton have mainly been well pronounced in physics where he made a number of discoveries. Firstly, he managed to discover that light can be split in many colors – not just one. In all the discoveries and researches he came up with, the universal law of gravitation is one of the most famous as it even came from his observing the falling of objects to the ground instead of the other way round. Giving tribute to his discovery of the force of gravity, and its universal law even led to the naming of the SI unit for force as the Newton. In addition, through his consistent experiments, Isaac Newton discovered the three laws of motion which have been named as Newton’s Laws of Motion.

His works also extended to some discoveries he made in optics which later made it easy for others to develop the other technological inventions that followed later. But, even in mathematics, Isaac made great contributions in various areas. Firstly, he discovered the calculus method of dealing with mathematical problems. But his reluctance to have his works published led to some rival scientists and mathematicians attempting to take credit when they made earlier publications of his works. In the same field of mathematics Newton also made a discovery of the binomial theorem concept.

Some nice quotes by Sir Isaac Newton:

  • To every action there is always opposed an equal reaction.
  • Plato is my friend — Aristotle is my friend — but my greatest friend is truth.
  • Tact is the art of making a point without making an enemy.
  • If I have done the public any service, it is due to my patient thought.
  • God created everything by number, weight and measure.
  • I can calculate the motion of heavenly bodies, but not the madness of people.
  • Gravitation is not responsible for people falling in love.

Bhopal disaster, the terrible gas tragedy

Bhopal disasterThe night of 2nd and 3rd of December, 1984 still remains memorable in the minds of the people and the government of Madhya Pradesh because of what happened on that fateful night. This is the day the Bhopal Disaster happened. The Union Carbide India limited which used to manufacture and produce phosgene monomethylamine (MMA), Sevin which is also referred to as pesticide carbaryl and methylisocyanate is the industry involved in this disaster.

What happened is that the MIC storage tank with 40 metric tons of MIC mixed with water which entered the tank by mistake causing a chain reaction that led to;

  • Rise in temperature
  • Increase in pressure
  • Led to further reaction of the steel tank producing a lot of gas
  • MIC and vapor to escaped in to the neighboring village killing people in their beds and in the streets

Those who were affected by the gas were easy to note because they showed the following signs

  • Vomiting
  • Burning sensation in the eyes
  • Burning sensation in the throat

When one inhaled this gas, it clogged the lungs by causing internal secretions which made breathing difficulty. In some cases some people experienced spasmodic constriction of the bronchial that led to massive suffocation, the results of the accident led to;

  • Dead – 300
  • Injured 200,000- 600,000

How it happened?

According to the findings, the disaster was caused by a combination of legal, technological and errors attributed to human beings. The seepage of 500 liters of water in to the MIC tank was massive and is suspected to have triggered chain reactions that led to the disaster.

The effect of the accident was exuberated by the following factors

  • Failure of containment
  • Lack of safety measures
  • Lack of community information
  • Lack of community procedures


The aftermaths of the accidents are many and varied and are still being felt right now.

  • The area has not be decontaminated fully
  • Compensation was not adequate
  • The area is still dangerous
  • Another 30,000 people have died after the accident
  • Over 500,000 people have been  infected
