Anti corruption activist Anna Hazare believes Prime Minister Narendra Modi's decision on Tuesday night to wipe out black money by scrapping the currency note of Rs 500 and Rs 1000 was a revolutionary step and could lead to the begining of a "new India marching towards a corruption free society "

Meet The Man Behind PM Modi's Decision To Demonetize Rs.1000 And Rs.500 Notes

The sudden announcement of the demonetization of Rs.500 and Rs.1000 currency notes by Prime Minister Narender Modi has caused an uproar all over the country. The idea of this drastic change came from Anil Bokil of Arthkranti, a Pune based financial think tank.

ANIL BOKIL 

Bokil reportedly met PM Modi a few months back to give a presentation on financial reforms and was given a mere 9 minutes to put forward his take on the issue. He suggested some key measures to control the flow of black money, the main one being a ban on big currency notes. Apparently, his arguments were quite intriguing to PM Modi and he kept discussing the matter for almost two hours. 

The main suggestions by Bokil were :

1. The collection of money under 56 different taxes should be stopped except for import duty.

Why RBI is issuing ₹2000 Rupees Notes ?? Read here 👇

No, New Rs. 2000 Note Will Not Have a 'Nano GPS Chip' 

IT WAS A RUMOUR..... sorry 

*why RBI is issuing ₹2000 Rupees Notes *

The Rs 2000 currency is designed keeping in mind to eradicate the black money issues using state of the art indigenous nano technology, every Rs. 2000 currency note is embedded with a *NGC (Nano GPS Chip)*

*How the embeded NGC Technology Works?*
The unique feature of the NGC is it dosent need any power source. It only acts as a signal reflector. When a Satellite sends a signal requesting location the NGC reflects back the signal from the location, giving precise location coordinates, and the serial number of the currency back to the satellite, this way every NGC embedded currency can be easily tracked & located even if it is kept 120 meters below ground level. The NGC cant be tampered with or removed without damaging the currency note

*How will this help eradicate black money menace?*
Since every NGC embeded currency can be tracked. The satellite can identify the exact amount of money stored at a certain location. If a relatively high concentration of currency is found a certain location for a longer period of time at suspicious locations other than banks & other financial institutions. The information will be passed on to the Income Tax Department for further investigation

*Just a beginning of the end of black money in India*

Our units of measurement are finally about to get an upgrade... THE NEW METRIC SYSTEM

Our units of measurement are finally about to get an upgrade

The new metric system

By the end of 2018, a kilogram will no longer exist as we know it, with our standard units of measurement finally scheduled to get a much-needed upgrade for the first time in more than 50 years.

Under the new proposal, all seven basic units of measurement - including the second, the kilogram, and the metre - will be defined by constant properties of nature, such as the speed of light, rather than by a value thought up by a bunch of scientists. And it's going to make the world a whole lot more accurate.

☆ What does 20/20 or 6/6 mean?

☆ 20/20 and 6/6 (6/6 is the metric measure) only indicate how sharp or clear your vision is at a distance.
