Great Thoughts by Mandar

Thoughts given below is my own observation & no copied from anywhere:

"Creation is the only greatest thing a man can do in this world", then it may be in the form of either a discovery or innovation. The creation should be followed by the whole world including creator. It is the toughest thing a man can do in this world. Man's intellectual thinking capability can be best utilized only in this job.

"Doing something without an objective is all waste".

Human Sea

Since last 4 months I have been traveling through local bus of Hyderabad.
I feel they are like sea or lake composed of drops. Each human is a drop.
Hence many of such a "Human Drop" constitutes a sea inside the bus.
The density of this human sea is about 2, means bus handles the mass 2 times more than its capacity in the busy hours (Morning 8:00 to 11:00 and evening 5:00 to 8:00)

They are static inside the bus means they are not in motion inside the bus.

It gives reminiscence of a term (Especially in above mentioned hours) called "fluid statics or hydrostatics" which I studied in a subject called Fluid Mechanics in my 2-1. There was a law associated with it known as
"Pascal's law".

The notion goes like this,"a change in the pressure of an enclosed incompressible fluid is conveyed undiminished to every part of the fluid and to the surfaces of its container".
(Dont bother i have copied the above statement from wiki")

So for our human sea i can simply say that while the bus is traveling our human sea is in hydrostatic equilibrium till there is no disturbance.

Now, if you throw a stone in the water the waves are produced and they diminish till the pressure difference is zero. we can say they are back in equilibrium.
Or even if you take out small amount of water outside u can observe same phenomenon.

Same is the case with our human sea.
Disturbances in this case are
1. passengers getting down.
2. passengers boarding.
3. But the main disturbance in this sea is somewhat resembled to a phenomenon in fluid mechanics called "hammer blow", exactly i am referring to conductor. This has a very high penetrating power and here I remind slip and twinning phenomenon from a subject called Material science and engineering in which a crack propagates through a material and finally it damages the material, in our case it damages the equilibrium. The subject also tells about strengthening techniques of material but those are not applicable here.
Because so called conductor is like a tool made of diamond by which any material can be broken.
Anyway as our material is a fluid it will not break, only the equilibrium will get disturb for some time.
But surely any density of human drops is not sufficient to stop the conductor.

He will be like a free electron which is not getting a partner to form a covalent bond with, so it will continue to move freely within the sea.

Although at all the shores (bus stops) all of the above disturbances take part in disturbing the hydrostatic equilibrium, till the next stop comes equilibrium is established. The pressure wave flows through all drops & finally to the container means the body of the bus, which makes a creaking sound right from when the engine is cranked.


Finally human drops travels happily till next shore& it continues till sea hits last "shore".
There new refreshing drops enter to form the sea & same continues.........................................
