Electricity – Late 19th century
Before the 19th century, electricity hadn’t been discovered and people had to rely on burning wood or coal to heat their homes and cook dinner. Today, we get energy delivered to us at the flick of a switch. Find out how electricity works.
Internet - 1960s
Although the first workable prototype of the internet came into existence the late 1960’s, it wasn’t until 1990 that the World Wide Web started taking shape the way we know it. Computer scientist Tim Berners-Lee invented the web as a means of accessing data online in the form of websites and hyperlinks.*
From then on it, the internet developed quickly, with the first image being uploaded in 1992. By 1993, it was made free for everyone to use and develop, which completely changed the game and transformed the impact it would have on the world.
Today, it’s an integral part of our every day existence. We access it on our phones, our TVs and even on our watches. The internet has completely revolutionised the way we access information every single day, has changed the way we communicate and transformed the global economy.**
Refrigeration - 1850s
Before the fridge came along, people had to store their food in ice or salt to stop bacteria from growing on it. The invention of a fridge completely changed the way we eat. Find out how a fridge works.
The personal computer - 1970s
The first PC was introduced to the world in in 1975. By 1976, Apple’s Steve Jobs and Steve Wozniak designed the Apple I and followed up with a colour computer (the Apple II) in 1977, which featured expansion slots and floppy drive support.
1981 was one of the most significant years for PCs, with the introduction of IBM PC. IBM brought out a machine that was based on ideas from the Apple II and presented people with more options, such as two floppy drives, a colour display adapter and monitor and an operating system.
The automobile - late 19th century
Can you imagine having to walk to Queensland to pick up some bananas? Before cars, people could only get from A to B by foot, horse or train.
The invention of the automobile completely revolutionised peoples’ lives. Automobiles finally allowed people to go anywhere they wanted, whenever they wanted, quickly. They gave people more freedom of movement, making it possible to purchase goods from far-away lands and even take up work in places far from home.
The history of the automobile is an extensive one and dates back to the 15th century when Leonardo da Vinci first created models for transportation vehicles. There are different opinions lying around regarding the inventor of the automobile, but many credit German engineer Karl Benz who developed the first practical car with petrol internal combustion engines in 1885.***
