What if Wheels were Never Invented?

Wheels are believed to have been invented almost 5500 years ago.

Ever imagined what the world would be like without wheels? How would you go to school, work or even on a holiday? Bicycles, cars, steam engines and even planes, nothing would be possible without the wheels. Yes, horses and sledges would be there. But it would be a super slow and super rough ride. Not only in transportation, but wheels are also a major component of the industrial revolution. Elevators, blinds, cranes, etc., all have some form of wheel hidden in them. Now, on adding teeth to wheels, gears were invented. Clocks, grinders, car engines, bicycles and other complex machines work with the help of gears. So, basically, if wheels were never invented, we might still be living the prehistoric way.

How do QR codes work?

QR codes allow symbols, phrases and URLs to be hidden from sight. But how do they work? A QR Code (QR stands for ‘quick response’) is a two-dimensional matrix barcode that consists of a series of black modules arranged in a square pattern on a white background. They work by embedding a series of information within preset boundaries, the data being located and identiﬁed by a series of alignment, timing and positional patterns within the code. The codes are read by scanners and smartphone cameras installed with a QR-deciphering software (these tend to be freely available as apps, or in some cases, are natively installed in the phone’s ﬁrmware). In practice, this allows any smartphone user to hold their device up to a QR code and decipher its encrypted data, receiving a message, image or URL link. READ ALSO:- How a speaker works ?

How ASPs works?

The Web and the Internet began to really heat up and receive significant media exposure starting around 1994. Initially, the Web started as a great way for academics and researchers to distribute information; but as millions of consumers flocked to the Internet, it began to spawn completely new business models. Three good examples of innovative models include: • Amazon - Amazon (which opened its doors in July, 1995) houses a database of millions of products that anyone can browse at any time. It would have been impossible to compile a list this large in any medium other than the Web. • Ebay - Online auctions make it easy and inexpensive for millions of people to buy and sell any imaginable item. It would be impossible to do this at a reasonable cost or in a timely manner with any medium other than the Web. • Epinions - Thousands of people contribute to a shared library of product reviews. One of the Web's greatest strengths is its worldwide view a...
