The answer to my 1st Q: Mark & Scott Kelly will not eat the same food for the #yearinspace twin study. Wonder if they will note vitamin A & related substances intake for the ocular aspects of the larger study.
NASA astronaut Scott Kelly and Roscosmos cosmonaut Mikhail Kornienko will embark on the first joint U.S.-Russian one-year mission, underscoring the “international” in International Space Station as the partners exemplify multilateral cooperation with regard to science.
An old timer in town for our local biker weeks remembered the fraction that used to be used to calculate #pi right off the top of his head: 22/7 Quite a feat to my modern dis-intellect. It works out to 3.1428571 This may explain a lot of disconnect in generational thinking, all things being relative and all. Happy Birthday Albert
