Week 3 [4.04 - 10.04] Life-Changing Science Discoveries


We live in the world technological revolution, cyber civilization. The discovery, invention, ideas are the elements, without which the modern world would not exist. Here’s a look at some discoveries that have changed the world. It’s impossible to rank their importance, so they’re listed in the order they were discovered.

The Copernican System

Copernican system, model of the solar system centred on the Sun, with Earth and other planets moving around it, was formulated by Nicolaus Copernicus, and published by him in 1543. The Copernican system gave a truer picture than the older Ptolemaic system, which was geocentric, centred on the Earth. It correctly described the Sun as having a central position relative to the Earth and other planets.

Gravity

The discovery of gravity has become an important stimulus for the intellectual development of humanity. The reason is that in the days before the discovery of this phenomenon people had believed that what is visible in the sky - stars, planets, the sun, the moon - is governed by completely different rules than the objects of our environment. Newton showed that the same basic law applies to both the fall and the severity of the bodies, as well as the motion of planets and comets. It  was a real breakthrough in science and philosophy – we look at the universe as a whole.

Electricity

The existence of electricity was already known in ancient times, however, only in terms of the ability to attract small wooden objects by rubbed amber.
If electricity makes life easier for us, you can thank Michael Faraday. He discovered electromagnetic induction (Faraday's law of electromagnetic induction) and  self-induction, then constructed the first electric generator, the forerunner of the huge generators that produce our electricity, and the electric motor.

Evolution

Charles Darwin, a British naturalist, published a book titled "The Origin of Species"  in 1859. The impact on science, and then the whole of Western culture, was huge.
Darwin argued that all life is the result of natural forces completely devoid of purpose, the product of time and chance cases, and the process, which he called "natural selection."

Louis Pasteur

Louis Pasteur, a French chemist and microbiologist, proved the existence of microbes. He worked on the infectivity of fowl cholera, anthrax and swine erysipelas. He confirmed that the only effective prophylactic procedure against infectious diseases would be protective vaccination.

Penicillin

In 1928, Fleming, growing  bacteria in his laboratory, accidentally discovered penicillin. But only 10 years later, along with Howard Walter Florey and Ernst Boris Chain he isolated the active substance and a year later antibiotics started to be produced. In 1945 they were awarded the Nobel Prize. Previously, infectious diseases were the cause of death and severe complications of hundreds of millions of people. The introduction of antibiotics revolutionized the treatment.

DNA

James Watson and Francis Crick in 1953 made a breakthrough discovery of the molecular structure of DNA. Our genes are made of DNA which determines, for example, our hair and eyes color. The discovery of DNA structure is also used in other fields, from paleontology to the criminology.

X-Rays


Wilhelm Roentgen, a German physicist, discovered X-rays in 1895. Just two months later, this radiation was used in medicine. X-rays go right through some substances, like flesh or wood, but are stopped by others, such as bones and lead. This allows them to be used to see broken bones or explosives inside suitcases, what makes them useful for doctors and security officers. Roentgen was awarded the first-ever Nobel Prize in Physics in 1901.

Comments

There is so many discoveries that made this world so much different than it was. The sad part is that if we were back in hundreds year each of us would have no idea how to invent this this, despite from fact that we should know that. We use so many things and we have no idea how they were made. For me the huge step was invention of airplane.

It seems funny that nowadays we struggle with invention of new apps for phone and this is our problem but in comparison to such great inventions this apps doesn't matter at all. But personally I know so many people that are willing to say that the biggest invention for them is Facebook.

I hope that there will be more and more brave people willing to make theirs dream come true and we will invent more and more medicines, objects and maybe time machine or so ever.
These are without a doubt great discoveries. What bothers me the most is that there are people don't "believe" in them, like evolution in case of die-hard creationists or quite popular recently flat earth movement, whatever they call themselves. But the thing about science is that it's true no matter if you believe it or not.

Thanks for your article. It is a pill of science and short introduction to the most important discoveries. We know more really important event for humanity, not only discoveries.
Btw, have you ever been in Toruń? It is Copernicus city. I really like to be there and I recommend it all of you. It is friendly city. Warsaw has its own Copernicus Science Center and Toruń has his own Copernicus Planetarium.
You show us people from whole world who has contributed to evolution. Many Polish people have affected evolution and revolution of humanity, for example: Maria Skłodowska- Curie, Romer, Łukasiewicz, Staszic, and many more.

As you stated those are great discoveries. I'm also flabbergasted that there are people who in the XXI century deny evolution and I'm glad there are not many people in Poland who hold such a position. At least I don't think they are very vocal? I may be wrong because I'm not religious but I guess that the catholic religion is more accepting of the evolution theory than the christian faction spread through United States. I just don't remember people at any of my schools opposing the theory of evolution. Have you heard about the museum of creationism in US? Anyway I'm really worried about the new anti vaccines movement that unfortunately got to Poland. I just don't understand why people would want to go against progress than with it. People should evolve, not hold onto flawed ideas. Where would we be if all those inventions and theories would have been suppressed?

I don't quite know what to say about this topic, except for each of us it's obvious how important were these inventions to the world, and I think we all learned about it in elementary school.
Undeniable truth is that on these theories based the whole science.
I wonder that people will discover something breakthrough in the near future. A great place to learn about this kind of thing is the Copernicus Science Centre in Warsaw. It's large fun for children and adults :)

Today, people can’t imagine life without some of the inventions.
Everyday life without eg. electricity would look completely different. Moreover medicine wouldn’t be on this level. Nowadays doctors know how to treat the disease, that once people died. Many inventions are so obvious to people now. We can’t work, cook without it. It is simple.

I agree that we think of those discoveries as so obvious we forget about them or their inventors/discoverers. Too bad you didn't mention poor Mr Tesla ;)

Also, it's pretty amazing how nomenclature changed as science evolved; centuries ago everyone doing any thinking/experimenting was called the universal title of 'philosopher'.

Wow, that was rather quick walk through ages. Although there were many important discoveries in between, I found it pleasant to reflect on how much of the stuff we consider obvious had to be discovered in someones lifetime scientific carer.
Unknown said…
The thought that human was able to figure out all this things is overwhelming for me. Hundreds of years of passing knowledge from one to another led us to this point in time when we got all this inventions close by. It's amazing and crushing at the same time. It's became so common for us that we ain't appreciating it anymore.

Thank you for very nice article. Once I interested in the inventions in terms of those that it have influenced our lives. Unfortunately, currently there are fewer and there are many inventions that have not found practical implementation which is also reflected in the many gadgets "that have no purpose." One of the most important inventions which I would add to your list is measurement of time and date. It is not a material thing but the system developed by the Phoenicians actually is the most useful and functional thing. I recommend reading the book '1001 Inventions that Changed the World' by Jack Challoner for more details :)
Unknown said…
Yes, I agree those are big and life-changing scientific discoveries.

I totally agree with your point of view. We can more and more but we understand less and less and we even dont try to understand. Years ago, we fought for survival now its all about comfort in life. It is disturbing but at the same time we are part of it so i feel a bit as hypocrite.
Those were obviously only a few discoveries out of many. We shouldn't forget that there were many ground-braking discoveries in between those or also before them all.

A good list nonetheless :)
You were right in your assumption, Catholic Church is actually more accepting of evolution. The most respected members of pontifical academy of sciences actually deny any historical accuracy of the Bible. And they advise the Pope on scientific subjects or maybe even tell him exactly what he should say.

So that's nice of them that they don't spread more ingorance in this case and we don't have the problem they do in the States.

For me on the greatest discoveries was Oxygen. Oxygen was first discovered by Swedish pharmacist Carl Wilhelm Scheele. He had discovered it by about 1772. Priestly shared his discovery with the French scientist Antoine Lavoiser. Lavoiser was able to show oxygen supported animal life respiration.

The other great discovery was Anatomy. It is the field of anatomy that today helps medical professionals all over the world to understand and treat the human body. Diagnosis or treatment of various conditions would have been nearly impossible if the mankind had no knowledge of the anatomy.

And of course Electricity. Michael Faraday made two big discoveries that changed our lives. In 1821, he discovered that when a wire carrying an electric current is placed next to a single magnetic pole, the wire will rotate. This led to the development of the electric motor. Ten years later, he became the first person to produce an electric current by moving a wire through a magnetic field. Faraday's experiment created the first generator, the forerunner of the huge generators that produce our electricity.

These are indeed very great things these talented people came up to but i guess that without a circle any of these things and all our discoveries and great inventions would be made. It is the very basic geometric form to create anything - just look around you and you see it everywhere - outside and inside, on things and inside things - it allowed us to make a move forward in the simplest and most important way in my opinion - it made our lives more convenient - not only in purely physical way, but also in math, imagination and all that kind of stuff.

Week 11 [03-09.06.2019] The problem with ecological cars emission in UK

The problem with ecological cars emission in UK Since the adoption of the European Emission Allowance Directive in the European Parliament, all car makers have tried to submit. Since 1992, the Euro I standard has been in force, which limited the emission of carbon monoxide to the atmosphere. The Euro VI standard currently applies, which limits the series of exhaust gases. These include: hydrocarbons, nitrogen and carbon oxides, and dust.   The most significant change was brought by the Euro IV standard. For the first time it introduced the limitation of nitrogen oxides, which are responsible for the harmful compounds of smog.   What is smog?   Smog consists of sulfur oxides, nitrogen and carbon. In addition, solid substances such as suspended dust (PM). Dust suspend in atmospheric aerosols may be in liquid and solid form. These can be particles of sea salt, clouds from the Sahara and artificial compounds made by people. These compounds often come fr
