Science for the Twenty-First Century



By Paul Hoyningen-Huene, Marcel Weber, Eric Oberheim


The second half of the 20th century has witnessed a great number of scientific discoveries and technological innovations which have had, and continue to have, the greatest impact on humanity and are frequently closely interconnected. The origins of the universe, the evolution of life on Earth, the structure and function of bio-molecules and

many natural phenomena, ranging from the subatomic to the cosmic scale, are far better understood today than they were 50 years ago.

At the same time, the progress that scientists have made has provided unforeseen power, which enables us to change our lives, our world, as well as our future. On the other hand, this power can also have negative consequences. It is a factor that has contributed to the damage to the Earth's natural environments and it has been used to construct weapons of mass destruction - reminding us that with power comes the responsibility to use it wisely.

At the dawn of the 21st century, science finds itself in a challenging situation. Today, there are more professionally trained scientists than in all previous generations combined together. At the same time humankind's most pressing challenges such as food supply, public health, global climate change, or the protection of biodiversity seem to escalate. So, there is a need in combined scientists’

efforts. The globalization of markets, production, and

finances may lead to a shift

from national research and development priorities

towards a world-wide

network of research activities.

Apart from large-scale research programmes which require international co-operation, scientific research which provides little or no

 

short-term economic profit may be called into question.

The twentieth century saw more momentous change than any previous century: change for better, change for

worse; change that either

brought enormous benefits to

human beings or threatens the very existence of the human species. Many factors contributed to this change but the key factor was the progress in science.

Nevertheless, in the next 50 years science will continue to surprise us both with what it discovers and creates.

Text A Mathematics differs from the other sciences in that its subject is not nature. Progress in mathematics is usually not directly realized by the public since its results are so abstract and often isolated from every-day experience that they are difficult to understand. However, occasionally some mathematical news becomes visible to a broader public. One example is the application of large prime numbers for encryption purposes. Sometimes a result in pure mathematics also catches public attention like the recent proof of Fermat’s last theorem, which resisted the best efforts of mathematicians for more than three and a half centuries. But mathematics is more than just peculiar theorems and occasional popular achievements. Because of its precision and accuracy, it is an essential tool for all of the sciences. There are many examples from the history of science in which the development of new mathematical methods allowed scientists to formulate fundamentally new theories and to achieve revolutionary conceptual breakthroughs. One of the most spectacular cases in this century was Einstein's use of the non-Euclidian geometry developed by Riemann in the 19th century to formulate the general theory of relativity. The last part of the 20th century has seen spectacular advances in mathematics, especially in the theory of dynamical systems and in stochastic analysis*. A combination of analytical and geometrical ideas has been characteristic of these developments. One example is the use of diffusion-reaction equations* to understand biological pattern formation*. Another example is the advances in our understanding of turbulence, in particular in the context of weather forecasting. At mid-century, mathematics was examining its own foundations. Today we see a different trend, which is strongly influenced by recent advances in computing technology. Mathematical modelling, the development of algorithms, and scientific computing have become powerful tools for all the sciences. They promise to play a crucial role in future progress.

Text B The chemical sciences have made breath-taking advances during the last five decades. They have provided innumerable benefits through an extremely wide range of applications. These include not only new materials, food additives, pharmaceuticals, and pesticides, but also new analytical tools for the study of living matter as well as the environment. The structures of many molecules were determined and this has provided the basis for their synthesis and production on an industrial scale. Notable examples are vitamins, which complement many biochemical reactions in the human body, and antibiotics, which have saved many lives. In addition to characterising and synthesising a vast number of natural products, chemists have also designed absolutely new compounds. Major progress was also made in the synthesis of tailor-made polymers*, composite materials, and ceramics which is capable of superconduction. Organic chemistry was instrumental to the great advances in understanding the structure and function of biomolecules. This has had an enormous impact on the bio-medical sciences. For instance, in 1954, the first naturally occurring protein hormone was analysed and then synthesised. For the first time, it was shown that an artificially produced protein has exactly the same properties as those naturally produced. The synthesis of insulin, a life-saving protein for diabetics, followed shortly thereafter. In 1959, the three-dimensional structure of haemoglobin (the oxygen-transporting molecule that makes blood red) was determined at atomic resolution*. Since then, the structures of thousands of biologically important molecules have been described. This knowledge plays a vital role in the development of new diagnostics and therapeutics. Aided by fast computers, medicinal chemists increasingly use the knowledge of bio-molecular structures to design small compounds with very specific pharmacological properties and make significant contributions both to our understanding of life processes and to medicine. The chemical sciences are also contributing to the environmental sciences. For example, they provide new materials and contribute to the development of new means to crop protection, as well as animal and human health.

Text C Over the last fifty years, our own solar system and its origins have become much better known. Many new satellites and rings around planets have been discovered and the nature of comets has been disclosed. One of the main reasons for this development was the beginning of the space age. All of these innovations were made possible by new observation instruments. Fifty years ago, the largest telescope was a 5-metre optical telescope, whereas modern telescopes are four times larger and more powerful. Furthermore, in 1990, the Hubble space telescope was sent into orbit. It has provided a lot of new information about our universe, as the radiation it collects does not have to pass through the Earth's atmosphere. From the early 1960s on, communication satellites were sent into orbit, making wireless communication possible all around the world. Landings on the Moon and the planets by probes of ever-increasing sophistication started in the mid-1960s and continue today. Some of them have brought back samples making an in-depth chemical analysis of their composition possible. In 1969, the first man set foot on the moon, only twelve years after the first satellite was launched. Another example is the development of weather satellites, which have become indispensable for tracking hurricanes and other violent storms. While these storms are still potentially dangerous, timely warning of their approach has saved many lives and helped to avoid vast property damage. Another example is the Earth resource satellites, which have become an integral part of geological data collection and provide us with a better means of assessing the Earth's resources. In addition, these satellites supply information about forest growth and crop diseases*.

2. Now exchange information with other students in your group to list all the achievements mentioned in texts A, B and C.

 

Comprehension check

1. Look back in the text and find 9 adjectives that are similar in meaning to the word important. Check in the dictionary the difference in their meanings.

 

Focus on language

1. Read the sentences and determine relationships between the parts in each sentence.

§ Innumerable benefits include not only new materials, food additives, pharmaceuticals, and pesticides, but also new analytical tools for the

study of living matter.

§ The scientists have made the progress that has provided unforeseen power, which enables us to change our lives, our world as well as our future.

§ Because of its precision, mathematics is an essential tool for all of the sciences.

 

Showing relationships between ideas   To connect words and phrases that have the same grammatical function in a sentence we use conjunctions, prepositions and adverbs. § conjunctions* e.g.: The twentieth century saw much momentous change that either brought enormous benefits to human beings, or threatens the very existence of the human species.  
Both … and … when connects two subjects require plural verb
Not only … but also … Either … or … Neither … nor … when connects two subjects, the latter determines whether the verb is singular or plural  
  * The samegrammatical form should follow each word of the pair. Neither … nor …is already negative in meaning so doesn’t require negative form of a verb   § prepositions e.g.: Apart from large-scale research programmes, scientific research with little short- term economic profit may be called into question.  
Because of … Due to …*     are followed by an object noun show cause and effect
Apart from … Except for … In addition to … show contrast
continue the same idea

 

Due to … in formal writing is followed by a noun clause introduced by the fact that   § adverbs e.g.: The chemical sciences developed new analytical tools for the study of living matter as well as the environment.
As well as is usually followed by an object noun indicates addition

 

 

 

2. Change the following sentences using an appropriate conjunction, preposition or adverb. Translate the sentences into your native language.

a) Big cities suffer from air pollution. They also suffer from the shortage of fresh drinking water.

b) Nowadays biochemistry doesn’t provide an answer to the fundamental question of the generation of life on earth. Modern biology doesn’t answer this question either.

c) The research project will be funded from one of the sources: local or national.

d) The research project took a lot of time and much money.

e) The cost and size of computing power has been reduced. The design and implementation of the Internet allows access to information from all over the globe at an unprecedented level and speed.

f) Discovery and study of quasars, black holes and pulsars were made possible by new observation instruments.

g) The concentration of atmospheric carbon dioxide (CO2) is increasing because the vast amount of fossil fuels is burnt every day.

3. Study the timeline describing the evolution of paper and papermaking. Use time and sequence expressions in the Functional language box to tell the history of papermaking.

As old as writing

Study help: Time lines The time line provides a study tool that allows you to organize information that is presented chronologically. Time lines would be effective to use in classes in which you present historical, biological and other developments. To make the order clear and to show the sequence of events, we mention dates and time, and we also use various links and connectives.

Written communication has been the centre of civilization for centuries. However, putting thoughts down in a written form wasn’t always easy or practical. Paper has a long history, beginning with the ancient Egyptians and continuing to the present day. It has largely survived the test of time but now it is facing a new challenge from its electronic equivalent. A particularly fruitful way to look at the evolution of paper is to study how it has changed over time.

 

   
3500 BC Sumerians use cuneiform alphabet, pressed in clay with a triangular stylus. Clay tablets were dried and/or fired for longevity. Some even had clay envelopes,' which were also inscribed.  
3000 BC Egyptians created Papyrus, a material made from thinly cut strips from the stem of Cyprus Papyrus plant.  
2400 BC Date of the earliest surviving papyrus scroll with writing.  
200 BC Both Greeks and Romans used wax tablets, framed and backed with wood, for note taking, orders, correspondence, and other temporary communication.  
197-159 BC In the Middle East, near Pergamum, large herds of cattle are raised for skins to be made into what we now call 'parchment.' It was the most popular material for manuscripts until the 12th century.  
105 AD Papermaking was invented in China by Ts'ai Louen. Material used: plant bark, discarded cotton and old fishnets.  
300-700 Secret of papermaking crept out from China to Vietnam, Nepal, Korea and Japan.  
   
  First papermaking mill was established in Spain  
1300C. Papermaking reached Southern Italy, where, until quite recently, some of the oldest handmade paper mills in Italy were operating in the Naples area.  
  Johann Gutenberg invented the printing press.  
1700 C. Tremendous increase in papermaking led to a serious shortage of raw materials.  
  Saxon Keller invented a groundwood pulp.  
  Mellier Watt patented a chemical pulp.  
Late 18-th Nicholas Luis Robert created a machine that could produce a seamless length of paper. Paper production became industrialized with the advent of steam-driven paper making machines.  
1950s New material and fillers were used, new processed chemicals and dyers were developed.
