scientists were trying to solve a mystery.
미스테리를 풀고자 노력했습니다.
a vacuum tube like this one
What were they made of?
이게 뭘로 만들어진 걸까요?
physicist, J.J. Thompson,
magnets and electricity, like this.
이러한 실험을 했습니다.
of negatively charged particles
than the hydrogen atom,
약 2,000배나 가벼웠습니다.
the first subatomic particle,
첫 번째 아원자 입자를 발견했고
a completely impractical discovery.
비현실적으로 보였습니다.
there were any applications of electrons.
않다고 생각했거든요.
he used to like to propose a toast:
톰슨은 건배사로 종종
전자를 위하여."라고 했습니다.
out of sheer curiosity,
연구를 통해
understanding of the world.
무척 다다르고 싶어했습니다.
did cause a revolution in science.
과학에 혁명을 가져왔죠.
unexpected revolution in technology.
우연한 혁명도 불러왔습니다.
for curiosity-driven research,
시작한 연구를 하고 싶습니다.
I'll talk about today
has actually changed our view of reality.
실제를 보는 관점이 바뀌었습니다.
the electrons in the seat,
만지고 있지도 않지요.
살짝 겉돌고 있을 뿐입니다.
was actually built on this discovery.
많은 것들을 만들었습니다.
were the start of electronics.
if you remember, in your living room,
가지고 있는 물건이 되었지요.
텔레비전이 있었을 것입니다.
would our lives be
from here was the television?
when the electrons here
부딪혔을 때 말이지요.
screech to a halt inside the metal,
which we call X-rays.
빛의 형태를 내뿜습니다.
of discovering the electron,
to make images inside the human body,
being saved by surgeons,
and shrapnel inside their bodies.
도움을 주었습니다.
come up with that technology
better surgical probes.
만들어 내도록 방법은 없었지요.
with no application in mind,
순수한 호기심에서 비롯된 연구만이
of the electron and X-rays.
이끌 수 있었습니다.
for our understanding of the universe
우주와 입자물리학을 이해하는
very simple particle accelerator.
분자 가속기이기 때문이지요.
so I design particle accelerators,
저는 분자 가속기를 설계하고
이해하려고 노력합니다.
curiosity-driven research
real-world applications.
있는 분야입니다.
of those two things
about what I do.
for me to list them all.
너무도 많은 예들이 있습니다.
found something strange in his equations.
방정식에서 이상한 것을 발견했습니다.
on mathematical insight,
기반하여 추측하기에
a second kind of matter,
있어야만 가능한 것으로
when it comes in contact:
반물질을 찾아냈습니다.
every day in hospitals,
병원에서 매일
or PET scans, used for detecting disease.
PET 스캔에 활용합니다.
up to a higher energy,
that this tube,
더 높은 에너지를 부과하면
ionizing radiation to kill human cells.
만들 수 있습니다.
those X-rays where you want them to go,
암을 치료하는
are treated using radiotherapy.
방사선 치료로 치료를 받습니다.
are actually standard equipment
병원에서 사실상 표준 장비입니다.
both with you right now, right?
지금 모두 가지고 계시죠?

만든 칩이 있는데
없었을 것입니다.

탐구하였습니다.
to develop particle accelerators.
개발하여야만 했습니다.
let us split the atom.
분해시키도록 개발했습니다.
and higher energies;
that let us delve into the nucleus
just exploring inside the atom.
연구하는 것이 아닙니다.
how to control these particles.
방법을 알았습니다.
with our world
for humans to see or touch
만질 수 없으며 실제로 있는지
방법을 알았습니다.

about the nature of the universe.
궁금하였기 때문입니다.
new particles started popping up.
입자는 계속 나타났습니다.

우리가 꺼낸 세계의 기본 구조입니다.
about 35,000 accelerators in the world,
35,000개의 가속기가 있으며
제외한 숫자입니다.
incredible machines,
of tiny particles,
that are more complex
how incredible it is
표현할 수 조차 없네요.

curiosity-driven research.
사람에게 투자하기를 바랍니다.

보는 예술이다."
J.J. Thompson did just that,
on the subatomic world.
in curiosity-driven research,
투자해야만 합니다.

문제들이 있기 때문이지요.

curious and open-minded
열린 마음일 때의 연구 결과가
our discoveries will be.
이끌었기 때문이죠
ABOUT THE SPEAKER
Suzie Sheehy - PhysicistDr. Suzie Sheehy uses accelerator physics to help reinvent technology for applications in medicine, energy and beyond.
Why you should listen
Dr. Suzie Sheehy designs particle accelerators. She's fascinated by using accelerator physics to help us reinvent technology for applications in areas such as medicine and energy. Her research projects have ranged from the design of new cancer treatment accelerators to building a scaled-down experiment that models particle beams -- answering fundamental questions about the physics of beams that are beyond reach of computer simulations.
Sheehy is currently a Royal Society University Research Fellow at the University of Oxford, where she also teaches graduate-level accelerator physics. She completed her undergraduate degree at the University of Melbourne in her native Australia (BSc Hons 2006) and DPhil at the University of Oxford in the John Adams Institute for Accelerator Science (2010). She has held fellowships from the Royal Commission for the Exhibition of 1851 (Brunel fellow 2010-2013) as well as her current Royal Society Fellowship.
Alongside her research, Sheehy is a prolific public speaker, presenter and science communicator, for which she has received a number of awards including the British Science Association Lord Kelvin Award, Institute of Physics HEPP Group Science in Society Award and the University of Oxford Vice Chancellors Civic Award. She is an expert TV presenter for Impossible Engineering on Discovery Channel and has cowritten and delivered live headline shows for tens of thousands of students at the Big Bang Fair alongside well known BBC TV presenters. She regularly presents public and schools lectures around the UK and further afield at major science festivals and venues like the Royal Institution.
