Cooper also has a “law” named after him.  Cooper’s Law states that our technology is advancing at such a rate that the number of different wireless communications possible in one location, at the same time will double every 30 months.  This “law” has held true since the first transmission by Guglielmo Marconi in 1895.  To illustrate, due to the method of transmitting this first signal, with a spark gap transmitter, it took up most of the radio spectrum to send this signal.  So the technology at that time more or less just allowed for one signal to be sent at any given time at a certain location.  Since then, every 30 months, the number of signals that can be transmitted at one time in one location has doubled.

In the United States, 86% of the time people are using the internet on their mobile device, they are simultaneously watching TV.  The average American smartphone user also spends about 2.7 hours per day socializing on their phone.

In 1974, a scientist at 3M research laboratories called Stephen Silver was trying to find a new strong adhesive; instead he discovered an adhesive that was not too strong. This new adhesive would stick on all surfaces but could be removed easily without leaving any residue or damage to the surface. Silver had no idea what use he could make of this adhesive.

Four years later Art Fry, a colleague of Stephen Silverÿfds came up with the idea to use his ÿfdlow tackÿfd adhesive to stick his bookmark in his hymnal. He then further developed his idea and in 1977, 3M launched Post-it notes nationwide. For some reason the product did not do well as consumers had never tried the product.

Everybody uses a Post-it note today to write down something you might forget. You can use Post-its to remind somebody about something or even to remind yourself, as peopleÿfdÿfd generally tend to forget important tasks. In order to remember these tasks, they write what needs to be done on a Post-it and stick it onto a wall or something which they use or see very often. You can stick one in your notebooks for reference later.

Sticky notes seem to be a part of everyday life. They are found in homes, classrooms and offices. You may be wondering…how did the sticky note come to be? Well here is the answer…According to Post-it®Brand’s website, Dr. Spencer Silver, a 3M scientist, developed a repositionable adhesive, but he didn’t know what to do with his discovery. It wasn’t until six years later that his colleague, Art Fry, thought of a use for the adhesive.
