D:我曾经读过一个关于俄罗斯工程的故事,不知道是不是真的:美国花费了数百万美元开发了用于零重力的biro笔,俄罗斯宇航员只是使用了铅笔
最好的简单、有效和牢不可破的工程
O:最终他们从美国购买了那些笔,因为石墨颗粒有毒。
DW:I once read a story about Russian engineering, No Idea if true: US spent millions developing a biro pen for zero gravity, Russian Cosmonauts simply used a pencil
Plain, effective and unbreakable engineering at its finest
OmskVogel:in the end they bought those pens from US, as graphite particles are toxic.
