When NASA first started sending up astronauts, they quickly discovered that ballpoint pens would not work in zero gravity.
To combat the problem, NASA scientists spent a decade and $12 billion to develop a pen that writes in zero gravity, upside down, underwater, on almost any surface including glass and at temperatures ranging from below freezing to 300 C.
The Russians used a pencil.
Charles MayoDied 26 May 1939 at age 73 (born 19 Jul 1865). Charles Horace Mayo was an American surgeon and philanthropist who co-founded the Mayo Clinic and Mayo Foundation. During the frontier practice of their father, Dr. William Worrall Mayo, Charles and his brother, William J. Mayo, began their medical training early, first by observing him, and later by assisting him on patient visits and with autopsies. After medical school, the family practiced together. In 1914 they built a clinic for the integrated group practice of medicine. In 1919, the brothers turned over the clinic, assets, and most of their life savings, to the charitable organization now known as Mayo Foundation. |
