Things I never knew
Which was the first company to use barcode for sales?
On June 26, 1974, a 10-pack Wrigley's chewing gum was the first product logged in a grocery store by a barcoding system using the modern universal product code. Later that year, the Uniform Grocery Product Code Council became the UPCC which regulates the issue and use of all universal product codes. At the same time, companies pursued the use of barcodes in industrial and other applications.
In 1971, the Plessey Company developed a barcode scanner and tracking system for library book checkout. The Codabar barcode was developed by Monarch Marking Systems around the same time for blood collection and book tracking applications. Intermec developed Code 3 of 9, a barcode that could store alphanumeric information. All other codes prior to this could only represent numeric digits.
What is Einstein's Rule of 72?
The rule of 72 is a rule of thumb (credited to Albert Einstein) that investors use to approximate the time it takes for money to double at a given rate of return.
It states that if you divide the number 72 by any given rate of return (percentage), the answer you get is the time (years) it takes for money to double at that given interest rate (assuming you can get the same rate each year and it is compounded annually).
For example, if you earn 10% on your money it would double in 7.2 years (72 divided by 10 = 7.2). The value 72 is a convenient choice of numerator, since it has many small divisors: 1, 2, 3, 4, 6, 8, 9, and 12. It provides a good approximation for annual compounding, and for compounding at typical rates (from 6% to 10%). The approximations are less accurate at higher interest rates.
What is summer ploughing?
Ploughing one month in advance i.e. in the month of May for kharif crops is known as summer ploughing. There are the three usual harvests known as the kharif or autumn (June-September), the rabi or spring (October-March) and zaid or extra harvest (March-June).
Summer ploughing helps to kill weeds, hibernating insects and diseasecausing organisms by exposing them to the summer heat. Summer ploughing of groundnut is always advantageous.
What is Fat Tuesday?
Fat Tuesday is Mardi Gras, where gras is French for fat and Mardi is French for Tuesday. The name comes from the tradition of slaughtering and feasting on a fattened calf on the last day of a carnival. The annual festivities start on January 6 and build to a climax on Mardi Gras, or Fat Tuesday, which always occurs on the day before Ash Wednesday.
