Looking for my Parallel Universe!




The Quantum Theory is something that technical, scientific and any-big-term-phobic ‘me’ would generally stay miles away from. Heck, I don’t even know if it is more concerned with science or technology or both. But I’ll tell you what my modest ‘big-on-advice-n-little-on-information’ brain has understood of it through a lesson I teach in Class 11th, through the mind-blastingly awesome flick ‘Source Code’ and through my discussions about it with a dear friend.

It is an amazing theory that implies parallel universes could exist simultaneously along with our own, having their own history, events and often a completely poles apart turn of reality as compared to the one that has materialised in the otherwise normal world, as we know it. The ever eternal debate between reality and what we deem as real!

What is reality? Something that we are experiencing as of now or is this, the big, fat dream that would burst someday like a bubble and we would wake up to a different scenario?

I’ll first share with you the gist of this chapter I teach to Class 11th students and that evokes the maximum number of yawns and protests from most of the slackers. So if you yawn in betweendon’t you dare open your mouth for anything besides a mesmerized gape, we’ll know where you stand!

It is the story of a History professor/writer/lecturer who one day wakes up to find himself in a train that is heading from Pune to Bombay. There are some Anglo-Indians on board and the train bears the symbol of the East India Company. Flabbergasted, he first presupposes that he has somehow travelled back in time, but it is not so. He is in the same time zone and era but in a world that is unfamiliar to him. Upon a little investigative stunt, he finds out that this is a different India, in contrast to the one as we know. Here we have not been ruled by the Britishers for a hundred years and are instead self reliant and extremely progressive. Whatever pocketful of English influence is there on the Bombay soil, it is in way of trading and entrepreneurship.

He goes to the central library to search for the turning point of the events and from where had history become different in this world to our own. Upon digging his self written history books, he finally converges it all to The Battle of Plassey where Vishwas Rao, the Maratha ruler missed the English bullet by a fraction of a hair, leading to the subsequent morale boost of his army and victory against the English in the 1800’s. The British influence thereafter was reduced and Indian Marathas ruled the nation for half a century before it became democratic.

While OUR History reveals that Vishwas Rao was killed by the British army that eventually led to an irreversible expansion of the English empire, whereby they ruled us for the next century! The professor absent-mindedly keeps the note of the information in his pocket, moves out and gets embroiled in an argument with an angry crowd, beaten up to the point of becoming subconscious and wakes up again to find himself on his bed in the world that he calls his own.

He is then explained to that since the last two days he was in coma, after a collision with a truck and the near death experience-which he realizes may have somehow made it possible for him to make that transition. However, the professor has evidence of that note in his pocket to prove to the detractors that they are wrong and what he was relating was not his insane imagination or wishful thinking.
The movie ‘Source Code’ also revolves around a similar web whereby one person travels through time and space to find himself in a body unknown to him, to save the world from a potential bomb threat and thereby able to create different realities by going back and forth in time for eight minutes on each round. Sounds complicated? Read the storyhere.
                         
Is that not an amazing leeway?
The assumption that varied realities exist in the universe where different histories I never thought I could use this term in plurals are being made based on a turn of events or diverse decisions that might have been taken. If I put my own life at this parameter it makes me dizzy to just imagine the possibilities.

Forgetting the global potential, it makes me wonder if there is another world, where I may be living a different life based on some road less travelled that I decided to sojourn on. There could be a world where I may not be married but running my own media channel, as was craved by me some fifteen years ago when I stepped out of the threshold of school. Selfish na, you think....But that was the first crossroad that I had stood on, debating and churning within till I finally gave in to family pressures. And many a times I am confounded by the 'what if?' that could have transpired there.

 

How amazing if we could peer into these different worlds as though into crystal balls and then pick and choose which alternative best suits our disposition and perhaps live there happily ever after. It is even more awesome than the supposition of visiting our future through some time machine because that cannot be altered while here we get options. And I have yet to find a human being who dislikes the idea of options for anything and everything!

“There is no one reality. Each of us lives in a separate universe. That's not speaking metaphorically. This is the hypothesis of the stark nature of reality suggested by recent developments in quantum physics. Reality in a dynamic universe is non-objective. Consciousness is the only reality.”-says M.R. Frank, from the Royal Astronomical Society of Canada.

I find myself wondering at the concept of multiple realities. How do parallel universes connect? What are the exact processes by which mind interacts with matter at the quantum level? Would we ever be able to travel through time, space and realities like this? And would a technically-duhme ever be able to comprehend fully, leave alone use this scientific break-through, if ever achieved in our history? The universe that we live in has such a fascinating nature and there is after all something more complex than the brain...or is it really the brain’s complexity again, after all?

Har Ek friend Zaruri hota hai!!!

This new advertisemnt of AIRTEL is so cool. Very creative and an innovative idea...check out the lyrics...

Chai ke Liye jaise toast hota hai--Vaise har ek friend zaroori hota hai
Aise har ek friend zaroori hota hai
Koi subah paanch baje neend se jagaye
Koi raat ko teen baje jaan bachaye
Ek teri kadki mein sharing kare
Aur Ek tere budget mein sneak in kare
Koi nature se guest koi host hota hai
Par har ek friend zaroori hota hai
""Ek ghadi ghadi kaam aaye par kabhi kabhi call kare
Ek kabhi kabhi kaam aaye aur ghadi ghadi call kare""
Gossip ka koi ghoomta phirta satellite
Koi sath rahe toh kar de sab alright
Koi effortless koi forced hota hai
Lekin har ek friend zaroori hota hai
Chat Room friend koi classroom friend
Koi bike pe race wala vroom vroom friend
Shopping mall wala shopping friend
Koi Exam hall wala copying friend
Movie buddy groovy buddy
Hi buddy--Bye buddy ----Joke buddy Poke buddy
Gaana Buddy Shaana buddy ---Chaddi Buddy Yaar Buddy
Kutte --kamine---
Everybody---Sab buddy
A to Z
Gin din ke naam bheja Roast hota hai
Par har ek friend zaroori hota hai
Lekin har ek friend zaroori hota hai"
Check the video out in youtube.....osam ...just loved it

Rocking Earthquake of 2011-09-18

A New Day, A new Hope, but the fear of Earthquake the previous day was still hunting me and it might be hunting to many other people as well.  National Seismological Centre claimed that the 6.8-magnitude quake that hit almost all parts of the country was the biggest since 1934. Along with many destruction many people lost their life as well.  Life was like stopped in some point, phone lines were dead, electricity was cut and mind was blank. People say and talk about safety methods about the earthquake, but i realized, how helpless you get in front of Nature. Living in the narrow lanes of Patan was so scary, and hearing the sounds from the walls, roofs, seeing the mud coming down really scared me a lot. check these pictures out which i didn't click myself but thought that should keep it, 



Stay safe.....stay happy!!

PHYSICS BEHIND ENGINEERING


   Prakash sharma
             
 Civil engineer
As engineering deals with principle of science and mathematics and their application for the efficient use of resources with care for the environment, so we can clearly develop an idea that knowledge on science (mostly on physics) is vital for any engineering field.
Today the world is growing rapidly in terms of innovative ideas, technology and there has taken place number of construction which is better and bigger than the previous one. All  these has been made possible through constant research ,hard work  and creative ideas which in turn has been achieved only through thorough knowledge and understanding of related subject matter. Considering the fact that there are different engineering branches and each one differs from other in the terms of subject matter and application of science principle (structural engineering uses mostly mechanics, hydropower engineering uses basically principles of hydraulics and so on) but nevertheless the theories of science studied by all the branches are same, they differ only in the depth of knowledge they require and content they are interested in.
Being a civil engineer it would be wise to mention the dependency of civil engineering with physics. Civil engineering is a professional discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including works like roads, bridges, canals, dams, and buildings.
Road network is the fundamental construction for transportation and there is lots of physics in its design. Geometric elements of road such as sight distance, overtaking sight distance, horizontal curve etc are all designed according to physics based principles. Sight distance which is length of road visible ahead to the driver at any instance uses Newton’s laws of motion and energy conservation principles for its determination and therefore designer is always orientated to provide sufficient sight distance for stopping operation.
Physics principle are widely used during horizontal curve design as when a vehicle traverses a horizontal  curve , the centrifugal force acts horizontally outward through the CG of the vehicle. The centrifugal force is counteracted by the transverse frictional resistance developed between tires and the pavement which enables the vehicle to change the direction along the curve and to maintain stability of vehicle. In order to counteract the affect of centrifugal force and to reduce the tendency of vehicle to overturn or skid the outer edge of pavement is raised with respect to inner edge, thus providing transverse slope throughout the length of horizontal curve, this transverse slope is super elevation
                                    e + f= V² / 127R
So whenever possible super elevation is provided in the curve so that passenger in vehicle does not get jerked while traversing the curve. These things are well taken care during road design.
Further buildings analysis and design are completely based on mechanics principle. The forces and deformation on the building elements are found by principles of mechanics. Equilibrium equations are used to find the internal forces in any building elements. The resultant of number of forces in equilibrium is zero and the moment of resultant about any point is zero. It therefore follows that algebraic sum of moments of all the force about any point is zero when these forces are in equilibrium.
 ΣFx=0 , ΣFy=0 ,ΣM=0
These three equations form the basis of mechanics and structural engineering. Further during the transfer of forces Newton’s third laws of motion are used.  And hence all the structural elements are designed such that internal stresses that develop are well within their permissible limits and thus users can feel safe about their life and properties.
So at this point  we have become quite aware of the fact that physics forms the basis of the engineering and all these achievements that has been made possible today by engineers  demands major credit  to the physicists who have developed the platform for the engineers to work..
