# Sir Isaac Newton’s 367th Birthday Today, Let’s Roll & Tribute !!

The 367th Anniversary of Sir Isaac Newton falls today. Sir Isaac Newton was born in England on 25th December 1943 (Please do not confuse with the birthday now being celebrated on 04th January as per the Gregorian Calender, this resulted, as England did not use Gregorian Calender during that era, but now we use it) Even you can see Google’s doodle dedicated to Sir Newton, if you visit Google today. It shows an apple falling down, recalling the famous theory of Gravity introduced by Newton to the world !!

As there were many occult-minded people during that epoch, he was not regarded nor rewarded for the wonderful theory he discovered, In addition he introduced the three laws of motions, which govern many parts of classical physics.

It should be noted that Newton introduced the universal theory of Gravity, thinking after the incident of a falling apple. The Universal theory of gravity is this,

Consider the following, imagining a field which houses 2 bodies with mass m1, and m2.

Then Let,

r= The distance between the centers of gravity of two bodies,
G = Universal Gravitational Constant equaled to 6.67 X 10^-11 N m^2/ kg^2 F = Force exerted by a body to the other, (Please understand that the Force exerted is equal on both bodies, where as the acceleration may vary depending on the ration masses.)

Then;

F=G*(m1)*(m2)/r^2 And here are the 3 laws of motion, explained by Newton.

I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

II. The relationship between an object’s mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.

III. For every action there is an equal and opposite reaction. (This is quite famous I reckon)

Moreover he rendered an immense service to the field of Optics as well !! He especially demonstrated how the light is made up of 7 colors by sending a ray of light beam through a prism !!

Therefore let’s tribute Sir Newton for the great work he’s done and left behind for us all !!

Long Live Sir Isaac Newton !!
