Science and Technologies

We have lots of different fields of science like physics, biology, chemistry, zoology, astronomy, medicine, astrophysics in school – civics. The importance of science and technology has grown dramatically over the last century. It influences every aspect of human lives: communication, health, transport, business, housework, transport etc. Technologies make our lives more comfortable, enjoyable, easy. Some famous scientists: Tesla (alternating current), Edison (direct current), Einstein (physical and mathematical laws), Fleming (who discovered penicilin), Koch (vaccination against tuberculosis), Wichterle (who invented contact lenses), Curie-Sklodowska (discovered radioactive elements), Bell (phone), Kepler (physical laws), ...

There are also inventions that are dangerous. Main of them are nuclear bombs and guns. But also, many things that were meant to help just ruin our life. I think that the biggest problem is using social network. Those connect people all over the world but stop the real conversations face to face. Children sit one next to each other, but no one is talking. They are online with their friends. They also share too much personal information on their profiles. But otherwise, it is good for making new friends, searching information, ...The second big problem which I see is that we are addicted to modern technologies. Imagine one day without electricity, without a fridge or your phone.

Modern technologies are harmful for natural environment. Gases from factories and cars causes the greenhouse effect. Petroleum in the sea from crashed boats kills most of organisms. Animals are dying because their natural habitats are replaced with urban places.

There is also the question about robots and artificial intelligence. There are naturally pros: robots can do repetitive work without getting bored or tired and they can work for long hours. They have rational behavior. They solve problems without emotions. They do exactly what they are programmed to do. But as technologies are getting high, people are afraid of robots, because after all they can be as clever as us and learn to feel emotions, then fight for their rights. Otherwise, they can also be dangerous. Maybe someday they can rise up and dominate humanity.

To end with something positive. Medicine made great useful progress in care, treatment and preventiv. Doctors use x-rays, magnetic resonance, they know many chemical substances that fight diseases like penicilin.

My gadgets: every day I use mobile phone (Xiaomi Redmi Note 8, I have it for, headphones, computer (consist of keyboard, mouse, speaker, camera – I have it from distance learning and of course display), fridge, kettle, ... I can’t live without it. At the weekend I watch television. Sometimes I use microwave, oven (mostly at the weekend), speaker, tablet, mixer, ...
