Each small change adds up. Try something new this week.

The Vulcan Street Plant began operating in Appleton, Wisconsin on September 30, 1882. Though small by today's standards, its 12.5-kilowatt output powered two paper mills and lit one house - establishing North America's first commercial hydroelectric service.

Fifty-three years later to the day, officials dedicated the Hoover Dam. The massive structure stretches between Nevada and Arizona, reaching 726 feet high. Construction costs hit $49 million ($1.2 billion in modern terms). Its completion proved large hydroelectric projects could succeed in North America.

September 30, 2016 brought different water-related challenges. Hurricane Matthew intensified over the Caribbean, with winds reaching 165 mph. No Atlantic storm had matched this strength in the previous decade.

Weather data shows Matthew's intensity fits a concerning pattern. As global temperatures rise, scientists track increases in extreme weather events. These three September dates highlight how water and power shape modern life - from innovations in clean energy to the growing impact of severe storms.

September 30th connects five people who changed science and society.

• In 1926, physicist Jean Baptiste Perrin settled a decades-old debate. His experiments showed matter exists as separate particles - not one flowing substance. French leaders took notice. They funded a national research center where scientists still track air particles using his methods.
• "Night" brought Holocaust horrors into clear view. Its author, Elie Wiesel, wrote from firsthand experience in Nazi camps. His Nobel Peace Prize funded real action - a foundation that sent medical teams into conflict zones. Until his passing in 2016, he spoke at 212 universities, pressing students to confront injustice.
• Dr. Barry Marshall faced skeptical colleagues in the 1980s. Standard medical texts blamed stress for stomach ulcers. So he drank a beaker of H. pylori bacteria. Three days of violent illness proved these microbes were the true cause. The 2005 Nobel Prize in Medicine followed.
• Ta-Nehisi Coates writes about race in America with rare directness. "Between the World and Me" takes readers inside his experiences as a Black father and son. The MacArthur Foundation called his work essential. The National Book Award soon followed.
• Working from a lab in Greece, Vassilis Papazachos tracked seismic patterns. His data helped Mediterranean towns spot earthquake risks. By 2022, when he died at 89, his warning system had detected 400+ dangerous tremors.
