1. Inventions of the past
In the pre-historic times, people’s lives were very simple – people hunted for food and made primitive tools from stones and simple clothes to protect them from the cold. The only tool which they had was the human hand. People wanted to make their lives easier and more comfortable and so they invented the wheel. They also built windmills to use the wind energy. Important discoveries and inventions came in 15th and 16th centuries – new continents /America, Asia, Africa/ were discovered and sciences such as astronomy, philosophy, medicine and biology were developed. At that time also the printing press /kníhtlač/ was invented in Germany by a man called Gutenberg.
Many important inventions came in the 18th and 19th century – it was the time of the Industrial Revolution:
- the steam engine - parní stroj => James Watt
- the electric light bulb – elektrická žárovka => T. A. Edison
- the electric motor – elektrický motor => Michael Faraday
- the 1st petrol driven car – první auto na benzín => G. Daimler, K. Benz
- the electricity – elektrická energie
Thanks to these inventions, large factories were built and everything started to be produced by machines => the mass production started and many goods became cheaper and so more people could buy them. Also the technologies improved and new and cheaper materials were used:
- glass – sklo
- paper – papier
- plastics – plasty
- synthetic materials – syntetické materiály

Later, in the 20th century, these inventions came to existence:
- the airplane
- the computer
- the mobile phone
- the Internet, the TV
- the credit cards

In the 20th century, scientists made a lot of medical researches that help doctors to save human lives and to cure many illnesses – for example:
- the laser
- new drugs and vaccines – lieky a vakcíny
- penicillin
- X-ray – rontgen
3. Inventions and technology that we use every day
Today we cannot imagine our lives without technology. We use it every day at home, at work, at school and in many other parts of our lives. They are very important to us. There are many inventions that we use every day.
For example at home we use:
- the fridge
- the washing machine
- the computer /PC/, the TV
- the electric kettle
- the dishwasher
- the microwave oven
- the vacuum cleaner /the hoover/"
