Technical Adaptation in Zero-gravity
Weightlessness can cause serious problems on technical instruments, especially those consisting of many mobile parts. Physical processes that depend on the weight of a body (like convection, cooking water or burning candles) act differently without a certain amount of gravity. Cohesion and advection play a bigger role in space. Everyday work like washing or going to the bathroom are not possible without adaptation. To use toilets in space, like the one on the International Space Station, astronauts have to fasten themselves to the seat. A fan creates suction that carries the waste away. Drinking is aided with a straw or from tubes.

Famous quotes containing the words technical and/or adaptation:
“The axioms of physics translate the laws of ethics. Thus, “the whole is greater than its part;” “reaction is equal to action;” “the smallest weight may be made to lift the greatest, the difference of weight being compensated by time;” and many the like propositions, which have an ethical as well as physical sense. These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.”
—Ralph Waldo Emerson (1803–1882)
“In youth the human body drew me and was the object of my secret and natural dreams. But body after body has taken away from me that sensual phosphorescence which my youth delighted in. Within me is no disturbing interplay now, but only the steady currents of adaptation and of sympathy.”
—Haniel Long (1888–1956)
