UNIT 4

CREATING MINDS

THE DEFEAT OF HABIT BY ORIGINALITY

When Alexandra the Great visited Diogenes and asked whether he could do anything for the famed teacher, Diogenes replied: “Only stand out of my light.” Perhaps some day we shall know how to heighten creativity. Until then, one of the best things we can do for creating minds is to stand out of their light.

FYI

− 63 −

creativity is the ability to develop new original ideas and to use the things available in a new way.

creative – (ant.) conventional

Opinions that are conventional are accepted as normal and right by most people.

PRE-READING TASK Study some grammar points.

I. We use an infinitive To V as the subject of the sentence.

Study the sentences. Find the predicate.

1.To raise new questions, new possibilities, to regard old questions from a new angle require a creative imagination and mark real advances in science.” Einstein

2.To repeat what others have said requires education, to challenge it requires brains.” Mary Poole

3.One can make reasonably accurate weather forecasts for periods up to five days, but to predict the weather much further would require both a very accurate knowledge of the present state of the atmosphere and impossibly complicated calculations.

II. Ving – a verbal noun

If a verb comes after a preposition (in\at\without\on\of\about\ before\after, etc) the verb ends in ing: V + ing

Study the sentences.

1.What are the prospects of obtaining a quantum theory of gravity and of unifying it with the other three interactions?

2.Science is an endless process of questioning.

We use by + Ving to say how something happens.

Study the sentences.

1.Tesla also explained the principles of a magnetic rotating field and induction motor by demonstrating how to make an egg stand on end.

2.Tesla investigated X-rays by using his own single node vacuum tubes. His device had no target electrode. The modern term for the phenomenon produced by this device is bremsstrahlung (or braking radiation). We now know that this device operated by emitting electrons from the single electrode by a combination of field emission and thermionic emission.

3.You can actually observe a background of microwave radiation coming from outer space by tuning your television to an empty channel.

III. The participle

V1 V2 V3 V4

to process – processed – processed (обработанный) – processing (обрабатывающий)

V3 is a passive participle; V4 is an active participle Ving … (Ved …) characterizes the noun it follows. Study the sentences.

1.Not all the scientists working in this field share this idea.

2.The speed of a pulse of light is the distance it travels between two events, divided by the time interval between the events.

3.Scientists believe that the universe is governed by well-defined laws. But the motion given by the laws is often chaotic.

4.A shock wave, called Cerenkov radiation, can be detected from the ground as a flash of visible light.

Note:

You translate a past participle V3 before you translate a N.

We sometimes put V3 before N, but we usually put V3 after N.

Study the sentences.

1.The stored information is then processed.

2.Each particle emitted corresponded to one quantum of light hitting the metal.

3.The data recorded were played back as visual patterns on a view screen

IV. Terminology

Any branch of exact sciences involves terminology.

1.Terms are expressed as a chain of nouns. The last N in the chain is the basic one.

1picture thinking

2a fuel source

3a thought photography machine

4a single node vacuum tube

5magnetic flux density

2.Terms are expressed as N + V3 + N

A “MAD” SCIENTIST

FYI

1.a neuron is a cell that is a part of the nervous system and that conducts messages to and from the brain.

2.a retina – your retina is the part of your eye, which receives the image that you can see. It sends the image to your brain.

Study the passage. Mind the underlined grammar points.

According to legend, Tesla was born precisely at midnight during an electric storm.

He studied electrical engineering at the Austrian Polytec (1875). However the university says that he stopped attending lectures and according to a college roommate, he did not graduate. He suffered a nervous breakdown during this time. He read many scientific research works on his own, memorizing complete books. He had a photographic memory. Tesla related in his autobiography that he experienced detailed moments of insight. During his early life, Tesla suffered a peculiar disease in which blinding flashes of light would appear before his eyes, often accompanied by hallucinations. Much of the time the visions were linked to a word or idea; just by hearing the name of an item, he would involuntarily visualize it in realistic detail. Tesla would visualize an invention in his brain in precise form before moving to the construction stage. This technique is known as picture thinking.

− 66 −

The strangest invention ever proposed by Tesla was probably “Thought Photography Machine.” He reasoned that a thought formed in the mind created a corresponding image on the retina, and the electrical data of this neural transmission could be read and recorded in a machine. The stored information could then be processed through an artificial optic nerve and played back as visual patterns on a view screen.

Another of Tesla’s theorized inventions is commonly referred to as

Tesla’s Flying Machine, which resembles an ion-propelled aircraft. Tesla claimed that one of his life goals was to create a flying machine that would run without an airplane engine, wings, propellers, or an onboard fuel source. Initially, Tesla considered the idea of a flying craft that would fly using an electric motor powered by ground based stations. As time progressed, Tesla suggested that such an aircraft could run entirely electro-mechanically. The theorized appearance would have the shape of a cigar or a saucer.

Tesla is also known for the invention of the Teslascope, a radio transmitter designed for communicating with extraterrestrial life on other planets.

COMMENT

INTERVIEW WITH CHITIN, AMERICAN MATHEMATICIAN

Study one of the points discussed in the interview. Mind the underlined grammar. Do the exercise that follows.

− 68 −

‘Bridge the Gap’ is a series of discussions and exchanges of opinions on science, art and humanity organized by the Center for Contemporary Art in Japan. This interview took place in a café at the airport, Paris, and continued late into the night.

----Can you tell me your thoughts on a scientific genius?

----In my opinion, there is an element of madness in the sciences as much as in the arts. Look at Wittgenstein, for example. He was a philosopher, not a scientist. He is a great philosopher, isn’t he? But he was a lunatic. But there are lots of lunatics in uninteresting way, aren’t there? My feeling is that to create a new theory of science, you have to be mad. You have to be crazy to think up something at a time when there is almost no evidence for it and go off in the direction from the rest of scientific community. And the scientific community usually fights against you. You have to be convinced that all the current theories are wrong and that the physical universe is completely different. It happens if you have a mind that goes beyond the framework of generally accepted ideas; the mind that is needed at the moment to take the next quantum jump. In fact, you have to have an encyclopedic mind.

--- What about Einstein?

When Einstein did his theories he had the right psychology for relativity, but he hated quantum mechanics. And he had no interest in high energy physics. He wanted to understand just the electron. He wanted fundamental knowledge. He was only interested in the most basic ideas. Murray Gell-Mann, who is at the Santa Fe Institute, is not at all like Einstein. He is interested in everything. He knows dozens of languages, he is interested in birds, and he has a tremendous memory. He has an encyclopedic mind, the kind of mind to deal with high energy physics, with the particle zoo. It is really a zoo and you need a mind that could take this enormous number of facts and organize it.

UNIT 5

COMPLEMENTARITY OF THINKING

“The main point of complementary ideas is that one way of looking at things, be it the scientific one, be it the religious one, be that the artistic one, is not enough, and deprives you of understanding your environment; but even more, it is very dangerous because if you have only one approach, it is open for abuse.”

Victor Weisskopf, theoretical physicist at MIT

PRE-READING TASK Study some grammar points.

I. There is used as the subject of the verb ‘be’. It is used when you want to say that something exists.

Study the sentences.

1.There are books to be read and thrown away; there are books to be read and put on the shelf; and there are some few to be read and digested. (Seneca)

2.There is no rule without an exception.

II. S + seems + to V = Russian – По-видимому; Создаётся впе-

чатление, что + S Study the sentence.
