This color photograph is over 100 years old! Learn how it was made


The man in this photo is Alim Khan. The photo was taken in 1911 and is one of the earliest color photographs ever taken. It was created by first taking three black-and-white photographs through red, green and blue filters, then projecting those photographs through similar filters which, when projected on a projection screen, created a full-color image.

The first ever permanent color photograph was taken in 1861 using an imperfect technique known as the three-color method. The earlier methods of color photographs were limited in the range of colors they could produce. The photo of Alim Khan was taken using a more advanced version of this method.

It was a challenge to find a method of color photography that worked well. The first commercially successful color process was called “autochrome,” and was introduced in 1907, but this was still limited. Kodak introduced “kodachrome” in 1935. It was an effective method, but one that required a lot of work to develop the photos.

It wasn’t until 1963 that Polaroid introduced instant color film. Unlike previous methods, cameras that used instant color film could develop a color photograph in just one-to-two minutes after exposure. Nine years later the company introduced integral film, which developed and fixed the photo without any intervention from the photographer.

Today most people use digital cameras which uses an electronic image sensor to record the image as a set of electronic data rather than as chemical changes on film. Digital cameras are much more convenient and have comparable image qualities to film cameras. There’s still a small market for film cameras, however, due to the potentially superior image quality and distinctive look.

Black boxes are made to withstand severe conditions— but they're not black, and they're not even boxes!


Any commercial aeroplane or corporate jet is required to be equipped with a cockpit voice recorder and a flight data recorder. It is these two items of separate equipment which we commonly refer to as a ‘Black Box.’ All recorders undergo countless tests that include exposure to a 1,110°C fire for an hour and 260°C heat for 10 hours. It is also able to operate between -55° to +70°C and it can carry a minimum 25 hours of flight data. It should also be able to withstand the pressure of being a mile under water for 30 days.

When Air France Flight 447 crashed into the Atlantic Ocean on 1 June 2009, all 228 passengers and the entire crew aboard were killed. Investigations were hampered because the aircraft's black boxes were not recovered from the ocean floor until May 2011 - nearly two years later.

Amazingly enough, the black boxes were still intact after such a long period of sea water and pressure exposure! The history of the flight as recorded by the black boxes revealed that the aircraft's crash into the sea was not a result of mechanical failure or severe weather conditions, but because the flight crew had raised the aircraft's nose, reducing it's speed until it stalled. They were unable to recover from the stall and crashed into the ocean.

Nokia has found a way to recharge your cell phone using radio waves. Learn more about their new technology here


Nokia is a Finnish communications and information technology corporation. They do business worldwide and are known for their internet services and cell phones. More recently, they have been working on a more environmentally friendly way to charge cellphones without wasting unnecessary electricity.

Nokia claims that it has created the technology to charge a cell phone using radio waves while that same cell phone is on standby mode. Standby mode is when electronics devices are not in use, but are still on. Similar to when computers hibernate. Even though the phone is not in use, it is still giving off radio waves. The same goes for televisions and computers.

The radio waves that a device gives off are very weak and small and do not hold much power. Nokia has developed the technology to gather all radio waves from miles away and from several devices. The more devices in a larger area means more power. The more power it has, the easier it would be able to charge a phone. This new technology suggests that when their phone is on standby mode, the phone will automatically charge without even being plugged in!

Some awesome lists!

Ever wonder why keys are in the order they’re in on the keyboard?


The keyboard we most commonly use today is called the "qwerty" keyboard for obvious reasons, but did you ever wonder why the letters are in that order?

It's actually because the original keyboards would jam if letters that were next to each other were pressed in too rapid succession.

In 1874 Christopher Sholes, who developed the layout, was aiming to slow typists down by putting the most common letters in the most hard to reach places, and thus reduce jamming.

Although modern technology has no issue with jamming, the keyboard stuck and is still the one we use today!

The average child today knows how to use a mouse and play a video game better than they can ride a bike or swim!


It's offical: we've entered the age of technology. Those of us who are constantly reminded by grandpa Smithers down the street that 'back in my day' was a better time and that all of us 'whipper snappers' are ruining society may finally be presented with a definition to 'we didn't have any of these fancy-pants gizmos when I was a lad.'

Modern children, because of their early immersion into the world of technology, have slowly become more and more unable to do simple physical activities that have been relished and made sport for ages. Almost immediately after birth we are monitored and attached to devices and technologies.

Children grow up with the option of staying inside and avoiding activities such as riding a bike that might harm them. It isn't then surprising to find out that most of them will choose the safer path. 69% of kids know how to use a computer mouse before they can tie their shoelaces. 58% know how to play a computer game before they learn how to ride a bike. That is over half of the population of children that has fallen to the complacency of advancing technologies.

Lesson to take away? Invest in your child's exo-cyber life! Otherwise, what will your kid do if one day we don't have electricity or internet?
