1. Read the text, translate it and do some exercises below.

The word “science” comes from the Latin word “scientia”, which means “knowledge”. Science covers the broad field of knowledge that deals with facts and the relationship among these facts.

Scientists study a wide variety of subjects. Some scientists search for clues to the origin of the Universe and examine the structure of the cells of living plants and animals. Other researches investigate why we act the way we do, or try to solve complicated mathematical problems.

Scientists use systematic methods of study to make observations and collect facts. They develop theories that help them order and unity facts. Scientific theories consist of general principals or laws that attempt to explain how and why something happens or happened. A theory is considered to become a part of scientific knowledge if it has been tested experimentally and proved to be true.

Scientific study can be divided into two major groups: sciences and humanities. They also have other names such as STEM, the arts and so on. As science, knowledge grew and became more complicated. Many new fields of science appeared. At the same time, the boundaries between scientific fields became less clear. Numerous areas of science overlap each other and it is often hard to tell where one science ends and another begins. All sciences are closely interconnected.

Science has great influence on our life. It provides the basis of modern technology – the tools and machines that make our life and work easier. The discoveries and inventions of scientists also help shape our view about ourselves and our place in the Universe.

As science, knowledge grew and became more complicated. Many new fields of science appeared. At the same time, the boundaries between scientific fields became less clear. Numerous areas of science overlap each other and it is often hard to tell where one science ends and another begins. All sciences are closely interconnected.

Digital humanities is a new direction in science, which began to develop especially actively in the last 5 years. It is a hybrid of the STEM and the humanities. But not in the sense that the humanities have suddenly decided to do physics. The main word here is still humanities, that is, the classical humanities – philology, history, philosophy, cultural studies. It is only proposed to study them in a new way – by ceasing to ignore the fact that the world is turning into digital.

Previously, researchers had dozens, hundreds, thousands of books on hand – today we are talking about millions. How can we study them if thousands of years are not enough to read them? Previously, tens of thousands of manuscripts were gathering dust in archives and were available only to a select few – now they are digitized, supplied with “smart” markup and intelligent search tools. How can we analyze and draw conclusions from this wealth of data? Previously, cartography was the lot of the elite – now everyone can place their coordinates on the interactive globe. How can you use Google Maps to learn new things about trade in the ancient world, the spread of plague in medieval Europe or air travel in the post-war USSR? All these questions forced humanitarian researchers to master skills and knowledge completely uncharacteristic for them – data analysis, data science, automatic text mining, network theory, geoinformatics. This is how “digital humanities” appeared.

And it is almost impossible to give an exhaustive definition of Digital Humanities. http://whatisdigitalhumanities.com/ has 817 different options – you can just refresh the page in your browser and read one by one. By the way, my favorite definition is: “DH is taking tools built by warmongers, oil companies, spy agencies & investment bankers and using them to study literature, philosophy, culture and the classics”.

In fact, formal studies of humanitarian objects have a rich history in the 20th century – poetry, historical databases, and stylometry. For linguists, however, working with text corpora and statistical data has long become mainstream. In fact, a new heyday of interest in exact methods in the humanities is associated with the emergence of new opportunities – the availability of electronic texts, the development of methods for their automatic analysis, new storage and processing capacities, new tools for working with data.

a. Here are the statements of scholars about what they do. Using the text, name the methods of DH they use in their work.

I create interactive maps of the correspondence of the French Enlightened.
	I measure anthropological material from paleontological and archaeological sites, and then create 3D portraits of people who lived millennia ago.
I build social networks of great poets using their letters and diaries.
	I process printed texts and then upload them into a system, which then allows other linguists to search for words, phrases, and whole sentences in different parameters.
I study medieval chronicles and mark conquest campaigns, trade ties between states and the spread of deadly diseases on Google maps.

b. The 20th century was marked by the emergence of many new disciplines at the intersection of two and sometimes three traditional ones. Below are the names of traditional sciences and humanities, make up the names of new ones.

geography linguistics informatics biology physics sociology geography nutritiology geology genetic engineering ethnology chemistry ecology astronomy

a. Read about inventions and name their scientific authors.

Albert Einstein Isaac Newton Thomas Newcomen Wilhelm Konrad Roentgen Louis Pasteur Alexander Fleming Michael Faraday James Watt I-Xing Thomas Severi Henry Bigelow Dmitry Mendeleev

— There is still a lot of controversy as to who can be considered the first mechanical watch. However, this groundbreaking discovery allowed people to measure time.

— Penicillin (the first antibiotic) was discovered in 1928. If this had not happened, then people would probably still die from things like stomach ulcers, tooth abscesses, tonsillitis and scarlet fever, staphylococcal infection, leptospirosis, etc.

— Rough forms of anesthesia such as opium, mandrake, and alcohol were used as early as 70 AD. But it wasn’t until 1847 that an American surgeon determined that ether and chloroform could be anesthetics, thereby making painful surgery much more bearable.

— The fateful discovery of electricity is usually associated with the name of one scientist, although this phenomenon was known to the ancient Greeks. But he can rightfully be considered the father of modern power grids and electrical appliances, because he discovered the basic principles of electromagnetic induction, diamagnetism and electrolysis. During his experiments, he also created the first generator that produces electricity.

— Pasteurization was discovered in the 1860s. It is a heat treatment process that destroys pathogens in certain foods and beverages such as wine, beer, and milk. This discovery had a huge impact on public health.

— This is a well-known story — the famous English mathematician and physicist discovered the force of gravity after an apple fell on his head in 1664. His discovery explains why things fall to earth and why planets revolve around the sun.

— It is common knowledge that modern civilization grew thanks to the Industrial Revolution, the main cause of which was the steam engine. In fact, this engine was not invented overnight, but rather it was gradually developed over about a hundred years thanks to 3 British inventors.

— In 1869, a Russian chemist, while studying the atomic weights of elements, noticed that chemical elements can be formed into groups with similar properties. As a result, he managed to create the first periodic table, which became one of the most important discoveries in the field of chemistry.

— The German physicist discovered X-rays in 1895 when he was studying the phenomena that accompany the passage of electric current through extremely low pressure gas. For this groundbreaking discovery, he was awarded the first-ever Nobel Prize in Physics in 1901.

— Two related theories – special relativity and general relativity – were published in 1905. They transformed theoretical physics and astronomy in the 20th century, replacing Newton’s 200-year-old theory of mechanics. This theory has become the basis for much of modern science.

b. This list of inventions is of course not exhaustive. Choose an invention that was not mentioned in the exercise and make a short presentation about it.

c. Watch some TED-videos (https://www.youtube.com/watch?v=Al-30Z-aH8M&list=PL006C004839E8F1C1) about inventions that make our everyday life easier and answer the questions:

1. What is the relationship between a treadmill and the English Penetration System?

2. How were the trains in the first London Tube put underground?

3. If Teflon is repellent, how is it used to coat pans, trays and cooking sheets?

4. Why were the first bras not popular?

5. How did someone’s awkwardness help invent the patch?

5. For a long time, women were deprived of the opportunity to receive a full-fledged education and pursue a scientific career. If any of them made significant scientific discoveries, they were declared the product of the work of male scientists. But some women still managed to write themselves in the history of science. Watch some TED-videos about them (https://www.youtube.com/watch?v=n1mwZrVJ-TI; https://www.youtube.com/watch?v=w6JFRi0Qm_s&t=2s; https://www.youtube.com/watch?v=BIP0lYrdirI&list=PL006C004839E8F1C1&index=26). Then read an article on modern women scientists (https://www.adme.ru/zhizn-nauka/11-zhenschin-uchenyh-kotorye-rushat-stereotip-o-tom-chto-krasota-i-um-nesovmestimy-2124515/?utm_source=AdMe_web&utm_medium=article&utm_campaign=share_image&utm_content=Facebook&image=6790065; https://www.youtube.com/watch?v=4wIBCoxuOJ0) and use this services (https://biteable.com/; https://www.powtoon.com/) to create short videos about their scientific careers and the discoveries they made.

Text 2. Technology

Technology means the use of people’s inventions and discoveries to satisfy their needs. Since people appeared on the Earth, they had to get food, clothes and shelter. Through the ages people invented tools, machines and materials to make work easier.

Nowadays, when people speak of technology, they generally mean industrial technology. Industrial technology began about 200 years ago with the development of the steam engine, the growth of factories, and the mass production of goods. It influenced different aspects of people’s lives. The development of the car influenced where people lived and worked. Radio and television changed their leisure time. The telephone revolutionized communication.

Science contributed much to modern technology. Science attempts to explain how and why things happen. Technology makes things happen. But not all technology is based on science. For example, people made different objects from iron for centuries before they learnt the structure of the metal. But some modern technologies, such as nuclear power production and space travel, depend heavily on science.

… most common type of… computer is … digital computer…. larg­est digital computers are … parts of…. computer system that fill… large room. … smallest digital computers — some so small they can рай through … eye of… needle — are found inside … watches, … pocket calculators, and … other devices.

Exercise 5. a) Read and state the function of the verbs be, have

All digital computers have two basic parts: a memory and a processor. The memory is receiving data and holding them until they are needed. The memory is made up of a big collection of switches (переключатели). The processor is changing data into useful information by the converting numbers into other numbers. It reads numbers from the memory, performs basic arithmetic calculations, and puts the answer back into the memory. The processor is performing this activity and over again until the desired result is achieved. Both the memory and the processor are electronic.

b) Fill in the blanks with the verbs be, have

People … used calculating devices since ancient times. The first electronic digital computer … built in 1946. The large room … filled with the computer.
