Endless Curiosity about science, math and universe

The short answer: Alfred Wegener, a Berlin-born meteorologist rather than a geologist, proposed on 6 January 1912 in Frankfurt that the continents once formed a single landmass, Pangaea, and had drifted apart. His big picture was right; his mechanism was wrong. Continents do not plow through ocean crust — they ride on plates. He died on the Greenland ice in 1930, about thirty years before the ocean floor gave the answer that vindicated him. The Korean version is 베게너는 누구일까? What evidence did Wegener have? Evidence Why it pointed to drifting continents Fitting coastlines South America and Africa fit together like pieces of torn newspaper Mesosaurus fossils This freshwater reptile is found only in eastern South America and southern Africa — it could not have swum the Atlantic Glossopteris plants The same flora appears in South America, Africa, India, Australia and Antarctica, and its seeds were too heavy to cross oceans Matching geology Mountain ranges and rock layers line up across ...

In short: Dynamite itself never became a drug. Its explosive ingredient, nitroglycerin, turned out to widen blood vessels — an effect first noticed in Alfred Nobel's own factory workers — and from 1879 it was prescribed for angina. The same molecule, at a vastly smaller dose and in a different context, went from blasting rock to saving hearts. How can an explosive and a heart drug be the same substance? Nitroglycerin was first synthesized in 1847 by the Italian chemist Ascanio Sobrero. The liquid was so unstable that handling it was perilous. In the 1860s Nobel mixed it with diatomaceous earth to create a far more manageable solid explosive: dynamite. Then, in Nobel's factories, something strange was reported. Dynamite Angina medicine Key substance Nitroglycerin Nitroglycerin Purpose Blasting, construction, mining Widening blood vessels, relieving chest pain Difference Dose and context — bulk explosive vs a tiny medical dose What did the factory workers discover?...

In short: WowScience Marathon EP1 strings together five stories that look unrelated — cheap Costco gasoline, pi hiding inside the prime numbers, Isaac Newton's investment collapse, Elon Musk's LiDAR argument, and Ignaz Semmelweis, the doctor who begged colleagues to wash their hands. They share one thread: behind every "obvious" common-sense claim, there is a calculation — and a human story. Five Stories, One Sitting Order Story Core question 1 The secret of Costco gas How can it be sold so cheaply? 2 Pi and the primes Why does pi appear in primes that have nothing to do with circles? 3 Newton's madness Why did the man who calculated the heavens fail at investing? 4 The LiDAR argument Why did Musk call LiDAR a fool's errand? 5 Semmelweis Why did "wash your hands" sound like madness? Why do these five stories work better together? Watched separately, they scatter across pricing strategy, mathematics, investment psychology, a technology...

TL;DR: In 1847, Ignaz Semmelweis cut maternal deaths from childbed fever from 18.3% to about 1-2% at Vienna General Hospital — simply by making doctors wash their hands in chlorinated lime. Instead of gratitude, the medical establishment ridiculed him, stripped him of his post, and in 1865 he died in a mental asylum. Two decades later, Pasteur's germ theory proved him right. Why did mothers die three times more often in one clinic than the other? In the 1840s, Vienna General Hospital ran two maternity clinics side by side. In the First Clinic, where doctors and medical students delivered babies, childbed fever killed more than one mother in ten at its worst. In the Second Clinic, run by midwives, the death rate was only 2-4%. The difference was nearly threefold. The killer was childbed fever — a bacterial infection spreading through the blood after childbirth, killing within days. The medical establishment of the day blamed "bad air" (miasma). What convinced him th...
