History as thought and as action

“All history is contemporary history” History as the Story of Liberty(1938), Benedetto Croce(1866~1952)

When, therefore, I spoke of history in an earlier lecture as a

dialogue between past and present, I should rather have called it

a dialogue between the events of the past and progressively

emerging future ends. WHAT IS HISTORY? (1961), Edward Hallett Carr(1892~1982)

Ranke's statement that history should embrace the principle

of wie es eigentlich gewesen (meaning "how things actually

were") was subsequently taken by many historians as their

guiding principle. Leopold von Ranke(1795~1886)

“있는 그대로의 역사＂

“모든 역사는 현대사다＂

“역사란 과거와 현재의 대화다＂



역사란 무엇인가?

Title & Description Speakers

Designing for virtual reality (2015 Google IO)

Designing great user experiences in virtual reality is considerably different than designing for the more traditional 2D

form factors that you may be familiar with. Virtual reality introduces a new set of physiological and ergonomic

considerations to your design work. Additionally, as a new medium users may not have established a familiarity with

interacting with virtual reality applications yet. And with an infinite canvas inside of your application, there are some very

real challenges with guiding the user’s focus and attention. We’ll review common interactive patterns for virtual reality

applications that work well. We'll also discuss best practices for rapid prototyping in virtual reality, and what the Google

VR design team has learned from crafting virtual reality applications.

A little badass. Beautiful. Tech and human. Work and love. ATAP.

Optimized for speed. Because we are, well, impatient. And someone should be. The engines on Project Ara are

revved. We’re on the road to Puerto Rico. Creating the hardware equivalent of the software app ecosystem

sometimes feels a little Dakar Rally, sometimes a little Le Mans. Fast. Difficult. Worth it. Speaking of fast… We’ll debut our

newest Spotlight Story ‘Fast-and-Furious’ style. Justin Lin’s live action short goes live at I/O. In full 360 with 3D sound sphere.

Whaaaat? Exactly. And wearables that we hope will blow your socks off. (We mean this more literally than you might think…)

Our goal: break the tension between the ever-shrinking screen sizes necessary to make electronics wearable and our ability

to have rich interactions with them. Why can’t you have both? We like to build new things. Sometimes seemingly impossible

things. We can build them faster together.

Material Design : Google IO 2014


Material design is a unified system of visual, motion, and interaction design that adapts

across different devices. Material design is inspired by tactile materials, such as paper

and ink. Material surfaces interact in a shared space. Surfaces can have elevation (z-

height) and cast shadows on other surfaces to convey relationships.

Raymond "Ray" Kurzweil (/ˈkɜrzwaɪl/ KURZ-wyl; born February 12, 1948) is an American author, computer scientist, inventor, futurist, and is a director of engineering at Google. Aside from futurology, he is involved in fields such asoptical character recognition (OCR), text-to-speech synthesis, speech recognitiontechnology, and electronic keyboard instruments. He has written books on health,artificial intelligence (AI), transhumanism, the technological singularity, andfuturism. Kurzweil is a public advocate for the futurist and transhumanist movements, as has been displayed in his vast collection of public talks, wherein he has shared his primarily optimistic outlooks on life extension technologies and the future of nanotechnology, robotics, and biotechnology. http://en.wikipedia.org/wiki/Ray_Kurzweil

엘론 머스크가 로봇의 인간 공격에 대해 또 경고했습니다. 엘론은 인공지능(AI)이 원자폭탄보다

더 위험하다고 말하곤 했죠. 이걸 탑재한 로봇이 5년 내에 사람을 죽이기 시작할 거라고 예고했

다네요. 50년 후가 아니라 5년 후.

비즈니스 인사이더 글. 엘론은 미래학 사이트(http://edge.org/ )에 경고 의견을 올렸다. AI가 발

전하면 로봇은 인간을 죽이는 게 합당하다는 결론을 내릴 거라고. "매우 위험한 일이 5년 내에

발생할 수 있다." 이런 괴상한 예측을 비웃는 사람도 있다는 걸 의식한 듯 이런 말도 했다. "내가

늑대를 알지도 못하면서 늑대가 온다고 외치는 게 아니다"고... 이런 의견 올리고 나서 몇 분 후

삭제했다.

엘론은 최근 살인 로봇에 관해 선지자적인 의견을 밝히곤 했다. 베너티페어 컨퍼런스에서도 킬

러 로봇에 관해 경고했다. AI가 발전하면 로봇이 인간을 스팸처럼 제거하려 들 거라고. 로봇의 역

할이 이메일 스팸을 제거하는 것과 비슷하다면 로봇은 스팸 없애는 최선책은 인간 제거라는 결

론을 내릴 거라고. 인터뷰 했던 이는 엘론에게 이렇게 묻기도 했다. 킬러 로봇이 지구를 장악하고

절망적인 상황이 오면 인간은 스페이스X 우주선을 타고 지구를 탈출하게 되냐고.

삭제된 엘론의 멘트. AI(좁은 의미로 말하는 게 아니다) 발전 속도가 믿기지

않을 정도로 빠르다. 여러분은 딥마인드 같은 그룹과 직접 접촉하지

않기 때문에 얼마나 빠른지 이해하기 어렵겠지만 거의 기하급수적이

다. 뭔가 매우 위험한 일이 5년 내에 발생할 수 있다. 길게 보면 10년이다. 내가 늑대가 뭔지도

모르면서 늑대가 온다고 외치는 게 아니다. 이렇게 염려하는 사람이 나 혼자가 아니다. AI 분야에

서 앞서가는 기업들은 만일의 사태에 대비하기 위해 많은 조치를 취하고 있다. 이들이 위험을 알

고 있기에 디지털 초지능을 통제할 수 있을 거라고, 악당 초지능이 인터넷으로 탈출하지 못하게

할 거라고 믿는다. 두고 봐야 한다.

엘론 머스크. 남아공 출신 천재 엔지니어/기업인. 1971년생. 펜실베니아에서 물리학과 경제학을

공부했고 스탠포드 박사과정 이틀만에 중퇴하고 창업. 페이팔 전신인 엑스닷컴 창업자. 스페이스

X와 테슬라 창업자/CEO. 책벌레+일벌레. "화성에서 죽는 게 소원", "화성에 식민지를 건설하고

싶다"고 말했던 화성인.
