Newton, Dear Isaac Newton

Well, i would never have thought of writing this blog until i was aware that people have misinterpreted NEWTON'S 3rd Law of Motion.

In School 6th std (i am 28yrs old now) we were taught:

"To every action there is a equal and opposite reaction"

While i was in 10th std (four years later), i was taught differently :

"Mutual forces of action and reaction in between two objects are equal, opposite . etc."

which stands true, that many don't care to accept.

I learnt that people have totally gone wrong, and have applied this single law exuberantly to discuss about "Butter fly Effect" which is an analogy of "Chaos Theory", and many other effects and forces. I do accept that newton's 3rd law and his other laws (what so ever it may be) may or does play a role in a chaotic system. A chaotic system may be affected by innumerable other laws that are known and unknown for that matter. Cause and effect is a philosophy would come close to "Butterfly effect" than newtons law. Newton's laws of motion are strictly applicable to what it says (Physics) and nothing else.

I hope there many sources on the net that can explain in detail. If you don't get any please comment i will write on it.

About Newton

Newton has been subjected to chaos, and that's my concern. The unmatched Newton was more loving than intelligent . I became a great fan of newton in my school days. I was taught the life story of newton in school, from which i learnt so many facts about him, i would take this opportunity to write about my learning.

He made two holes on his front door ,a big hole for the mother cat and a small one for its kitten. Newton was surprised to see that both mother and kitten passed through that same hole(the bigger one). He could calculate the motions of heavenly bodies but was unaware that both mother cat and its kitten can pass through the same hole.

His dog named diamond knocked a candle ,which burnt bundles of research papers that were so important that he could never redo. Newton said " Oh dear diamond, you know too little about what u have done". (I would have cut the dog to pieces).

He humbly said that he just discovered some pebbles on the shore.(his discoveries are pebbles? ;-)

Newton never needed an apple, crow shit would have been more than enough for this genius to calculate gravity.


The descendants of Newtons apple tree are still alive!


(Idiots are not idiots, they are busy thinking)

Nature will reveal secrets to Open eyes,Open ears and Open minds.
Open mouths please excuse.

I am a great fan of J.C.Bose too...........................

How fast are you traveling ?




How fast are you traveling with respect to earth?

Say you are traveling on a bike at a speed of 75 Kms/hr, means you are traveling with respect to the bike at 75 kms/hr. You are just seated while the bike is carrying you at a speed of 75 Kms/hr. So you are traveling at 75 Kms/hr. That is the point behind this question.

Earth is spinning and we are traveling with respect to it, but at what speed ?

Actually earth is not spinning at the same speed at all locations, it depends on where u are located. Somebody standing on the exact north pole or exact south pole is not traveling in any direction. He is just "spinning" with the earth's axis. Therefore his speed is 0 km/hr (that somebody is actually standing on the earth's axis). People located on the equator are traveling faster w.r.e (w.r.e = with respect to earth) than the rest. They cover the longest distance in a day's time (approx 24 hours), that makes him faster.

Everything that is in line with a latitudinal angle (irrespective of longitude) travels at the same speed.

A person in New Delhi w.r.e is traveling at the speed of 1469.599 Kms/hr. To be more precise, a person standing on top (exactly on the crescent) of Taj Mahal w.r.e is traveling at the speed of 1489.567 Kms/hr.

Now how do we calculate this?

Calculation :

Very simple, just calculate the circumference (length of equator) of the earth and divide it by 23.934 hrs (a day is 23 hrs 56 min 4 sec)
SPEED = LENGTH / TIME
Time is always the same that is approximately 24 hrs (actually 23.934hr), but Length changes depending on your location.

Speed at the Equator

The Earth has a diameter of 12,756.3 Km at the Equator. Divide it by 2 gives the radius 6378.15 km.
Letz get the circumference (Length of the Equator).

= 2 * pi x radius
* cos(d)
= 2
* 3.14159 * 6378.15 * cos(0)
= 40075.064517
* 1

( Note : pi = 3.14159, d = the angle of latitude. It is 0 degrees at the Equator and cos(0) = 1)

Now, Speed = 40075.064517 / 23.934 = 1674.39 Kms / hr (at Equator)


Since latitude angle is in respect to Equator (North or South ), circumferences at varying latitudes will be calculated with latitude degrees in respect to 40075.064517 (Length of Equator).

Latitude degree of New Delhi = 28.635308

Latitude degree of Chennai = 13.060416

Speed of New Delhi

To make it simple

40075.064517 x cos (d) and then divide that by 23.934

To know the value of cos(d) open your calculator in your accessory menu go to view menu and select scientific, degree and decimal. Type the latitude for New Delhi, it is d = 28.635308 and then press cos you will get 0.87768781925989138161384567012858 multiply this number with 40075.064517 you will get 5173.395982625182308587132810884 now divide it with 23.934. The result is 1469.5995647457667881919918446931, approximate it to three decimals 1469.599 kms/hr. Now, that is the speed of Delhiites. (You need not type these numbers, just copy and paste i.e. Ctr+c and Ctr+v)

You can get the latitude degrees of your city, street, house, your car parked on the street at http://www.findlatitudeandlongitude.com/.

Calculate your speed. Let people know that you are not idle and lazy but you are actually traveling at some 1000's of kms per hr.

I am typing this blog, staring at my laptop, in my room while i am traveling at the speed of 1631.0906 kms/hr. Thanks to gravity.

Speed = (40075.064517 x cos(27.175343680486694) ) / 23.934 = 1489.567 Kms/hr.
