We came all this way to explore the Moon, and the most important thing is that we discovered the Earth.
Interpretation
The essence of our lunar exploration was realizing the value of our own planet.
William Anders' quote emphasizes that while humanity's journey to the Moon represented a significant achievement in space exploration, it also led to a profound realization about the importance and fragility of Earth. The perspective gained from viewing our planet from space highlighted the interconnectedness of life and the need for stewardship of our home, suggesting that exploration can broaden our understanding of our place in the universe.

In fast moving fields like cancer, where doctors tailor treatments based on evidence that's constantly evolving, two years can be an eternity of waiting to learn about important science. For some patients, that interval can be fatal.
The Earth is round, and is inhabited on all sides, is insignificantly small, and is borne through the stars.
During the century after Newton, it was still possible for a man of unusual attainments to master all fields of scientific knowledge. But by 1800, this had become entirely impracticable.
One aim of physical sciences had been to give an exact picture the material world. One achievement of physics in the twentieth century has been to prove that that aim is unattainable.
Contaminated water is not a problem limited to Flint. Think of New Jersey, where school fountains were found to contain unsafe levels of lead. Or the EPA's 33,000 superfund sites, which are highly-polluted areas that require long-term clean-up operations. The problem is so large that it feels insurmountable.
Just because things get a little dingy at the subatomic level doesn't mean all bets are off.
