TEXT 1. PARTICLE PHYSICS TASK 1. BEFORE YOU READ: 1. When did particle physics start? 2. What does particle physics investigate? 3. What is modern particle physics focused on? TASK 2. READ THE TEXT: Particle physics (also known as high energy physics) is a branch of physics that studies the nature of the particles that constitute matter and radiation. Although the word particle can refer to various types of very small objects (e.g. protons, gas particles, or even household dust), particle physics usually investigates the irreducibly smallest detectable particles and the fundamental interactions necessary to explain their behavior. By our current understanding, these elementary particles are excitations of the quantum fields that also govern their interactions. The currently dominant theory explaining these fundamental particles and fields, along with their dynamics, is called the Standard Model. Thus, modern particle physics generally investigates the Standard Model and its various possible extensions, e.g. to the newest “known” particle, the Higgs boson, or even to the oldest known force field, gravity. Subatomic particles Modern particle physics research is focused on subatomic particles, including atomic constituents such as electrons, protons, and neutrons (protons and neutrons are composite particles called baryons, made of quarks), produced by radioactive and scattering processes, such as photons, neutrinos, and muons, as well as a wide range of exotic particles. Dynamics
of particles is also governed by quantum mechanics; they exhibit wave– particle duality, displaying particle-like behavior under certain experimental conditions and wave-like behavior in others. In more technical terms, they are described by quantum state vectors in a Hilbert space, which is also treated in quantum field theory. Following the convention of particle physicists, the term elementary particles is applied to those particles that are, according to current understanding, presumed to be indivisible and not composed of other particles. All particles and their interactions observed to date can be described almost entirely by a quantum field theory called the Standard Model. The Standard Model, as currently formulated, has 61 elementary particles. Those elementary particles can combine to form composite particles, accounting for the hundreds of other species of particles that have been discovered since the 1960s. The Standard Model has been found to agree with almost all the experimental tests conducted to date. However, most particle physicists believe that it is an incomplete description of nature and that a more fundamental theory awaits discovery. In recent years, measurements of neutrino mass have provided the first experimental deviations from the Standard Model, since neutrinos are massless in the Standard Model. History The idea that all matter is fundamentally composed of elementary particles dates from at least the 6th century BC. In the 19th century, John Dalton, through his work on stoichiometry, concluded that each element of nature was composed of a single, unique type of particle. The word atom, after the Greek word atomos meaning “indivisible”, has since then denoted the smallest particle of a chemical element, but physicists soon discovered that atoms are not, in fact, the fundamental particles of nature, but are conglomerates of even smaller particles, such as the electron. The early 20th century explorations of nuclear physics and quantum physics led to proofs of nuclear fission in 1939 by Lise Meitner (based on experiments by Otto Hahn), and nuclear fusion by Hans Bethe in that same year; both discoveries also led to the development of nuclear weapons. Throughout the 1950s and 1960s, a bewildering variety of particles were found in collisions of particles from increasingly high-energy beams. It was referred to informally
as the “particle zoo”. That term was deprecatedafter the formulation of the Standard Model during the 1970s, in which the large number of particles was explained as combinations of a (relatively) small number of more fundamental particles. DEVELOPING ACADEMIC VOCABULARY WORKING OUT THE MEANING OF UNKNOWN WORDS TASK 3.THE FOLLOWING WORDS ARE ALL FROM THE TEXT ABOVE. FIND THEM IN THE TEXT: deviation await conduct entirely observe TASK 4. FOR EACH WORD, READ THE SENTENCE IT OCCURS IN AND ANSWER THE QUESTIONS: a) Is the word positive, negative or neutral? b) Is it a noun, adjective, adverb or verb? c) Can you think of a word with a similar meaning (synonym) and one with an opposite meaning (antonym)? READING COMPREHENTION TASK 5. ANSWER THE QUESTIONS: 1. What does particle physics investigate? 2. When did particle physics start? 3. What can the word “particle” refer to? 4. How is the currently dominant theory explaining fundamental particles and fields called? 5. What is dynamics of particles governed by and what do they exhibit? 6. What is the term “elementary particles” applied to? 7. What is the “Standard Model”? 8. What does the word “atom” mean and what does it denote? 9. What branches of physics led to proofs of nuclear fission? 10. What is modern particle physics focused on?
