who said anything about algebra being from the US.
Algebra = 8th grade
at least you could mention a meaningful math that is used these days.
Sputnik was first like was Vostok too.
About the GPS, you can see Europeans sending Galileo and Russia have their own "GPS system" too. And since you don't care so much about the original idea and the Galileo system is more advanced than GPS, then I think we can call Galileo the main product and GPS just a first "idea"

considering military spec GPS is accurate to mm rather then 3 feet, sure it is.
