Moving Walkway
The
great Albert Einstein once told that speed is purely relative. I am still not able to understand his relativity
theory completely. If you are moving at a speed and your
surrounding also move exactly at the speed then, you feel, you are stationary. By
using the same concept, you can walk across a two fast moving belts if the
difference in speed is very Less: In Shenzen(China) I saw for the first time the
moving walkway. A day will come when we don’t have to wait for a car or a bus and we will get into this belt and travel fast as per our choice by moving to the faster moving belts. If such a system is available in India at all places, it would become a real boon for all. 
In another occasion when I was waiting at the bus stand( frankfurt) a person on a
wheel cycle came to the bus stop. The bus arrived immediately and stopped exactly at the bus stop. After this the bus tilted towards the bus stop and the door opened. Then the step pulled outwards enabling the wheelchair person to go inside the bus without any body’s
assistance. After he anchored himself inside the door was closed only after he pressed a button accessible to him.
I also remember another incident when I was waiting at the junction to cross a road ( In Orlando). The traffic did not stop at all. I was waiting for along time for the traffic to stop like in India but it did not stop at all. Then a couple came there and they pressed a button and the white signal to cross appeared immediately. I was not aware that we have to press the button to cross. Along with the light there was a
Tick..Tick…sound for a blind person to cross safely. I also noticed these these crossing stations have smooth ramps for a wheel chair person to drive his wheelchair.
One day these technologies will certainly come to india and we will enjoy these technologies. The truth is that though these technologies give you more freedom and self reliance, it would also bring more loneliness to your old age.
