놓치더라도 한 명의 무고한 사람이 고통받으면 안 된다(It is better that 10 guilty persons escape, than that 1 innocent suffer).” 18세기 영국의 법학자 윌리엄 블랙스톤 판사가 재판 중 남긴 말이다.이후 유죄 판결이 확정되기 전까지는 피고인을 무죄로 본다는 ‘무죄 추정의 원칙’은 영국과 미국 법률의 근간이 ...
including some religious groups, condemned the work, with one organization warning that artificial organisms could escape into the wild and cause environmental havoc or be turned into biological weapons. The new organismis based on an existing bacterium that causes mastitis in goats. But at its coreis an entirely synthetic genome that was constructed from chemicals in the laboratory. The ...
가압방식의 우주복을 다시 도입했다. 현재의 우주복은 1995년에 도입된 ACES(Advanced Crew Escape Suit)로 등 뒤 배낭에는 낙하산과 1인용 구명보트, 비상 산소통 등 각종 생존 장비가 들어 있다.하얗고 육중하게 생긴 우주왕복선의 선외활동우주복(Extra Mobility Unit, EMU)은 우주를 자유롭게 날아다니며 ISS나 ...
안에서 입는 우주복이다. 이에 비해 미국의 선내 우주복은 오렌지색의 ‘ACES’(Advanced Crew Escape Suit)로 일명 ‘펌프킨슈트’라고 불린다. 소콜 우주복이나 펌프킨슈트는 해발고도가 19km 이상에서 호흡에 필요한 산소를 공급하고 몸속의 체액이 끓지 않도록 압력을 유지하는 역할을 한다.소콜 우주복은 ...
it hard to think wisely about the effects this technology is having now, and will have in the future.OK. But we can't escape to a nice South Sea island — not with pollution lapping the shores and diffusing through the air. The planet is ONE, and we have to face up to the problems of our technology as they affect the entire Earth.With this preamble, it seems safe to launch into an update on ...
not worth worrying about right now.Then there's geology. Rockhounds collect their specimens in what must be a pleasant escape, but geology is not all rocks. It's about as close to home as any science can get, because geology is about our home, Earth Geologists are the scientists who study things like volcanic eruptions(only too likely to affect human living) and earthquakes.Yet when ...
the amphibians that waddled went fest if they needed to-which is apparent if you try to catch a salamander bent on escape. Furthermore, amphibians have reasonably good lungs, although many can breathe through their skins, too, have efficient three-chambered hearts, and may live longer than many small mammals.While contemplating the history of amphibians and the marvel of space tadpoles, I ...
to safety on a dragline.There are many kinds of orb spiders. My favorite is the one that captures moths, which can escape other spider webs by shedding the loose scales on their wings. This spider's horizontal web contains big drops of a glue-like substance on limp capture threads. The moth sticks to the thread, which breaks at one end, dangling the stuck moth until the spider notices and ...
어렵고 비(非)전문번역인들이 SF를 번역하다보니 'red giant'(적색거성)를 '붉은 거인'으로 'escape velocity'(탈출속도)를 '도망속도'로 옮기는 등 오역도 종종 눈에 띈다.회원들은 이를두고 "SF가 발전하지 않는 나라는 과학기술선진국이 될 수 없다. 미국이나 일본의 경우 SF황금기와 산업성장기가 일치했다 ...
in its immediate neighborhood is enormous. Anything that falls in can't get out, so it is a "hole." Even light can't escape, so it is a "black hole."A black hole is formed when a giant star explodes as a supernova. Part of it collapses, sometimes, into a black hole. Such a black hole is usually somewhat more massive than our sun. It tends to pick up material about it, without giving any back, ...
