Grandma was not well educated — she came from poverty in Italy, but science fascinated her, even if she didn't understand it. The moon landing gave her such joy even through her agony. Grandma passed on a few weeks later and I still miss her, but watching her awestruck face as she witnessed the moon landing still makes me smile.
It’s hard for recent generations to comprehend the speed and depth of scientific and technological advances made during the span of our grandmothers generation. Mine was born at the end of the 19th century probably about the same time as yours.
Consider this, they saw the first self-propelled flying machines, not much more than large manned kites, wondrous and awesome things and survived to see passenger jets become common and culminating in that manned lunar landing.
Couple that with the rest of the wondrous advances that transformed the world and realize that in that span of a single life the world changed in ways unlike any previous epoch.
An awesome thing to contemplate.
