Unit 9: The Dawn of Atomic Physics

All science is either physics or stamp collecting.

Ernest Rutherford

WARM-UP

  1. Think of as many words as possible related to physics. How important is physics to you?

  2. What are the branches of physics? Rearrange the letters to find out.

A

Atomic Physics

B

Molecular Physics

C

Classical Physics

D

Acoustics

E

Optics

F

Particle Physics

G

Solid State Physics

Continue enumerating the branches of physics: Astrophysics, Biophysics, Chemical Physics, Classical physics, Fluid dynamics, Geophysics, Nuclear Physics, Quantum Physics, Thermodynamics, Theoretical Physics

What does each branch deal with?

  1. Match the letters used in Physics with their phenomena they stand for.

    1

    A

    e

    electric current

    2

    E

    c

    electric field

    3

    K E

    f

    kinetic energy

    4

    M

    a

    magnetization

    5

    Q

    g

    electric charge

    6

    U

    b

    potential energy

    7

    S

    d

    entropy

  2. Discuss the following questions in small groups.

  1. Do you remember any important scientific discoveries and inventions in physics made in:

  1. the 19th century;

      1. the 20th century;

      2. the early 21st century.

  1. Do you know about physicists whose names are connected with our University?

  2. Name the departments / faculties and subfaculties which deal with physics.

  1. Do you agree or disagree with the quotations?

  1. "In the matter of physics, the first lessons should contain nothing but what is experimental and interesting to see. A pretty experiment is in itself often more valuable than twenty formulae extracted from our minds." Albert Einstein

  2. "The continuum is that which is divisible into indivisible that are infinitely divisible Physics" Aristotle

  3. "Physics is, hopefully, simple. Physicists are not." Edward Teller

  4. "In physics, you don't have to go around making trouble for yourself − nature does it for you." Frank Wilczek

  5. Nothing is accidental in the universe − this is one of my Laws of Physics − except the entire universe itself, which is Pure Accident, pure divinity." Joyce Carol

  6. "I am now convinced that theoretical physics is actually philosophy." Max Born

  7. “Learn from yesterday, live for today, hope for tomorrow. The important thing is to not stop questioning.” Albert Einstein

READING

  1. Underline the stressed sound in each word as in the example. Practise reading.

physicists, discovery, X-rays, photograph, through, mysterious, opaque, phenomenon, self-satisfaction, uranium salts, pure, honour, enough, conclusion, tons, possess, electrify, phosphorescent, triumphant, minute, hydrogen, weight, structure.
