Chap. 9 미시세계와 거시세계
Microscopic and macroscopic world!
We live in a wonderfully complex universe, and we are curious about it by nature. So we wonder why are we here? What is the world made of? Where does it come from?
Throughout the lectures I have tried to show you a hint of how we can find some of the answers. Now it is your turn to move ahead and find the answers. Good luck!

Chap. 8 양자의 세계
Quantum World
“If successful scientific theories can be thought of as cures for stubborn problems, quantum physics was the wonder drug of the 20th century. It successfully explained phenomena such as radioactivity and antimatter, and no other theory can match its description of how light and particles behave on small scales.” --- by Maggie McKee, NewScientist http://www.newscientist.com/article/dn9930-instant-expert-quantum-world.html

Suggested Questions
- 왜 하나의 물체가 입자와 파동의 성질을 동시에 갖는 것이 모순이 되는가? 우리가 이해하는 입자(particle)와 파동(wave)의 성질로 부터 추론해 보자.
- 원자 혹은 그 보다 작은 입자들의 존재를 입증하는 증거는 무엇인가? 우리 눈으로 직접 확인할 수 없는 간접적인 사실에 근거한 “원자” 혹은 “근본입자”의 존재에 대해 얼마나 확신할 수 있는가? 물체-분자-원자-핵-…. 식의 논리를 적용하면 더 작은 더 근본적인 ‘새로운’ 근본 입자를 생각할 수 있을까?
- 하이젠베르크의 불확정성 원리와 양자역학이 현대철학에 미친 영향은 어떤 것이 있나? 입자-파동의 이중성과 불확정성 원리가 사물 또는 자연에 대한 고전적 인식의 관점에 준 변화에서 출발해서 논의해 보자.

The Information Age, also commonly known as the Computer Age or Digital Age, is an idea that the current age will be characterized by the ability of individuals to transfer information freely, and to have instant access to information that would have been difficult or impossible to find previously. The idea is linked to the concept of a digital age or digital revolution, and carries the ramifications of a shift from traditional industry that the industrial revolution brought through industrialization, to an economy based on the manipulation of information, i.e., an information society. —- From Wikipedia

Chap. 6 G선 상의 아리아
Air on the G-String
Bach, Johann Sebastian, is one of the greatest composers of all time. His music combines profound expression with clever musico-mathematical feats, like fugues and cannons in which the same melody is played against itself in various ways. In this chapter, let us think about the sound played in the ‘Air on the G string’, how it works and what it implies in terms of physics.
