Wilhelm Röntgen was born in Lennep, Germany, but grew up in Holland. Röntgen earned his undergraduate degree at the Zurich university and received his doctorate in physics from the University of Zurich. Following his studies, Wilhelm Röntgen worked at universities in Strasbourg, Giessen, and Würzburg, where he carried out his Nobel Prize-awarded research. In 1900 Röntgen transferred to the University of Munich, where he remained for the rest of his life, despite plans to emigrate to the US

His discovery was a revolution in the field of physics and medicine, which earned him the first Nobel Prize in Physics in history in 1901 .

Wilhelm Roentgen randomly detects X-rays by conducting experiments with the emission of cathode rays (electron emission). He notes that the rays are able to penetrate opaque black paper wrapped around a cathode ray tube. This leads to the glow of the colors located on the next table.

The Internet

Invention that changed your lives

In the 1980s and 1990s, the Internet widened in scope to encompass the IT capabilities of universities and research centers, and, later on, public entities, institutions, and private enterprises from around the world. Today, we can send data from one end of the world to the other in a matter of seconds, make online presentations, live in parallel “game worlds,” and use pictures, video, sound, and text to share our real lives, our genuine identity. Personal stories go public; local issues become global.

Key issue surrounding Internet use is privacy. Internet users are becoming more sensitive to the insight that privacy is a must-have in our lives.the Internet revolution is not just technological; it also operates at a personal level, and throughout the structure of society. The Internet makes it possible for an unlimited number of people to communicate with one another freely and easily, in an unrestricted way.

From the basic needs to the utmost luxuries, almost every facet of your lives is now impacted by the internet. We can now connect with anyone, anytime and anywhere. Let’s take a look at some of the areas of our lifestyle where the internet played a significant role:

Impact on business

Education

Shopping and buying

Jobs and employment

International communication

All these changes can often lead to this question – is it all for good? The internet has changed the way we do close to everything, and with people questioning what their lives would be like without it, it makes us wonder, what negative effects has the internet had for us.It’s become quite obvious that people spend hours upon hours on the internet and this could have some serious health effects; people have often died from spending days in front of the computer. On a lesser note, there are things like back problems and eye sight.

Albert Einstein ( 14 March 1879 – 18 April 1955)

-was a German-born theoretical physicist who developed the  theory of relativity , one of the two pillars of modern physics.

Honorary Doctor of about 20 leading universities in the world, a member of many Academies of Sciences, including a foreign honorary member of the USSR Academy of Sciences (1926).

with his tongue hanging out

In 1905, Albert Einstein published a special theory of relativity (STR), which explained how to interpret movements between different inertial reference systems — simply speaking, objects that move at a constant speed relative to each other. Einstein explained that when two objects move at a constant speed, they should be considered to move relative to each other, instead of taking one of them as an absolute reference system.

Future energy

The running out of fuel reserves make humanity look for alternative sources of energy. One of the best options is solar energy. The history of solar energy begins with Archimedes and comes to the present day. Hundreds of scientists from the USSR, the USA, and the UK worked to create and improve solar cells.

• In developing countries, gas, oil and coal have become more expensive than solar energy.
• In the past three years, 60% of all solar panels have been installed. Countries occupying leading positions in the use of solar energy - Germany, Spain, Japan.
• 50% of all solar systems are produced in the Land of the Rising Sun for work in the homes of ordinary Japanese.

• Sunny weather is not necessary for the operation of the panels, energy is produced and in the clouds. The battery accumulates electricity on sunny days, and consumes it in cloudy and weatherless.
• According to the research of the German Aerospace Center: if you put solar panels in the Sahara, then 1% of the desert will be enough to provide electricity to the whole world!
• Chinese scientists plan to create the first solar power plant in space by 2020. The weight of the station will be about 10,000 tons, and the cost of development is $ 1 trillion.

The Printing Press

Johann Gutenberg

• From a small German town

• He combined earlier methods (woodblock printing, new types of paper, new scripts, etc.) into one to create the printing press

• Around 1450, Gutenberg discovers that a traditional wine press can be turned into a “Printing” press

The Wine Press and The Printing Press

Importance?

• Makes books, newspapers, etc. more easily available

• People more interested in becoming literate (learning how to read and write)

• Spreads ideas very quickly (the ideas from the Reformation and Scientific Revolution, etc.)

• Increases knowledge

• Printed in languages the people understood (not just Latin)

The wheel

• Probably the key invention that lead to the world as we know it. There is still an ongoing debate about which culture originally invented the wheel. It could have been the Mesopotamian culture around 3500 BC or the Indus Valley civilization. The oldest known wooden wheel – Ljubljana Marshes Wheel – was discovered in 2002 and is approximately 5,150 years old. The first known use of the wheel was as a potter’s wheel, which made it possible for people to live at a distance from sources of water and carry water to their dwelling place with the help of pots. Then, of course, the most important use of the wheel was discovered- for transportation. 

• The invention of the wheel changed the face of commerce and industry. It became easier for people, with the help of vehicles, to transport heavy items from one place to another. The invention of the spoked wheel also made these vehicles lighter and swifter. The use of wheel as a pulley made it easier to pull heavy loads, draw water from wells etc. It is almost impossible to imagine any machine today which does not use the principle idea behind the wheel.

elon musk

American engineer, entrepreneur, inventor and investor; dollar billionaire. Capital: $ 22.4 billion Born: June 28, 1971 (47 years old), Pretoria, South Africa

hyperloop

The Boring Company was founded by Elon Musk in 2016. Her main activity is drilling tunnels to create vacuum tubes with rapidly moving capsules. High speed of movement along the pipe is achieved due to minimal air resistance and support friction. The speed of movement of the capsule along the so-called Urban Loop from Elon Musk will be about 250 km / h. The cost of a trip around the city for ordinary citizens costs only $ 1. This facility, called Hyperloop, will allow you to travel from New York to Washington in 30 minutes.
