  7. "Since her death in 1979, the woman who discovered what the universe is made of has not so much as received a memorial plaque. Her newspaper obituaries do not mention her greatest discovery. […] Every high school student knows that Isaac Newton discovered gravity, that Charles Darwin discovered evolution, and that Albert Einstein discovered the relativity of time. But when it comes to the composition of our universe, the textbooks simply say that the most abundant atom in the universe is hydrogen. And no one ever wonders how we know."

    This 19th Century Map Could Have Transformed the WestToo bad Congress didn’t listen

    n the decades after the Civil War, Americans rushed headlong into the west. By 1890 Kansas and Nebraska had over a million inhabitants, and over six million lived in the seventeen states and territories that made up the region. It was a moment of palpable excitement about the region’s promise.

    In that moment of supreme confidence, however, one voice reminded Americans that these outsized expectations could never be realized given that west of the 100th meridianfrom the Dakotas down through east Texasthere was insufficient rainfall to sustain agriculture. That voice was John Wesley Powell, a hero of the Civil War who lost an arm fighting the rebels at Shiloh before leading equally heroic expeditions in the remotest areas of the west, most notably down the Colorado River. These expeditions convinced him that the scarcity of water would become the single most important influence in western development. Outside the Pacific Northwest, the arid lands of the west could not be farmed without irrigation.”
