5 Technologies That Changed/Or Will Change The World

1. Fibre Optics


Fibre optic technology was first demonstrated in the 1840’s by Colladon and Babinet. Fibre optic tubes refract light within glass tubes with little loss of light over the length of the tube.

In 1880 Alexander Graham Bell developed the technology to transmit voice signals over an optical beam. Bundled together, fibre optic cables are immune to electrical interference making them good for use in computer networking. Fibre optic transmissions are also much harder to snoop and are therefore considered more secure.

2. Graphene


Graphene will completely revolutionise technology. Created at the University of Manchester, UK, graphene is a layer of graphite one atom thick. It is very strong, an excellent conductor of heat and electricity and is predicted to transform mobile devices. Imagine a flexible cellphone or tablet.


3. Cellphone Technology


The technology to enable cellphones to communicate from a base station was proposed in 1947, however the technology did not allow the phone to move out of range of the base station.

A car phone call, using a rotary dial to make the call was first used in Sweden in 1956. The first mobile phone call was made from a Motorola phone in 1973.


4. Personal Computing


Microcomputers started to be mass marketed in 1977 and the name “Personal Computer” appeared six years later when Hewlett Packard announced its 9100A personal computer. Microchip technology has significantly reduced the cost — and size — of the processor as its power increased and form factors became much more compact.

Although there are well over a billion PC’s in existence, smartphone and tablet technology have started to become prevalent in consumer markets around the world.


5. Solar Cells


Solar cells convert light energy to electricity. The photovoltaic effect was first demonstrated by Becquerel in 1839. It has recently achieved a level of almost 45 percent efficiency. About 16 solar panels could be connected to your house and meet all of your energy needs.


See you all tomorrow.

Buh-bye.

Y2K Bug / New Blog

Image
Y2K bug, also called Year 2000 bug or Millennium Bug, a problem in the coding of computerized systems that was projected to create havoc in computers and computer networks around the world at the beginning of the year 2000 (in metric measurements K stands for thousand). After more than a year of international alarm, feverish preparations, and programming corrections, few major failures occurred in the transition from December 31, 1999, to January 1, 2000. Until the 1990s, many computer programs (especially those written in the early days of computers) were designed to abbreviate four-digit years as two digits in order to save memory space. These computers could recognize “98” as “1998” but would be unable to recognize “00” as “2000,” perhaps interpreting it to mean 1900. Many feared that when the clocks struck midnight on January 1, 2000, many affected computers would be using an incorrect date and thus fail to operate properly unless the computers’ software was repaired or r...

Mental Illnesses Personified

Image
Alright, so this morning I was sent a link this morning to 15 illustrations of mental illnesses represented as houses. It was really cool and thought-provoking, so, thanks to Nyla Grigsby for sending me the link. I'll share it here . Check it out, but not before you read this post (obviously). After looking through those pictures, I was reminded of a series of drawings I found a couple years ago with the same idea (only much more frightening - which I like). If you're not aware, every October, artists from all around the world participate in a drawing challenge called "InkTober" where they make one ink drawing a day for the entire month. In October 2016, an amazing artist Shawn Coss  decided to make his own original prompt for the month. Shawn wanted to focus primarily on personifying mental illnesses and disorders. These illustrations are crazy awesome, scary, realistic . Shawn manages to capture the struggle and turmoil of those who suffer with these illnesses...

GOING AWAY PARTY!

Image
HELLO LOYAL READERS! All 7 or 8 of you if I'm not mistaken. Thank you for continuing to read my blog every day for the last 310 days! Or, if you've just clicked on the links without reading the articles, that's also okay because it still shows up as if you did read it, so thanks for even clicking the links at all. I'm sure they were getting annoying after around day 50. Good thing I went on for another 260! So, I've been thinking about this move for a while now, and I think today is the perfect day to do it. While, yes, this will be the last post on this specific platform, it will NOT be the last you hear of me chucking my random interests into your faces. In fact, I like to think of this as an upgrade. An upgrade that will benefit all of us! Now that I've finally figured out how Patreon works, THAT will be where any blog posts, interesting articles, short stories and general updates on what's going on in my life will be posted. This way I can...
