Vacuum Bazookas, Electric Rainbow Jelly, and 27 Other Saturday Science Projects - Neil A. Downie - Bog - Princeton University Press - Plusbog.dk

Vacuum Bazookas, Electric Rainbow Jelly, and 27 Other Saturday Science Projects - Neil A. Downie - Bog - Princeton University Press - Plusbog.dk

How do you crack nuts with a piece of string? Reverse gravity? Cobble together a clock out of a coffee cup, a soda bottle, and some water? Use a vacuum cleaner and nineteenth-century railroad technology to fashion a makeshift bazooka that can launch paper projectiles? Create a rainbow in a block of Jello? This is a one-volume romp through a whole array of counterintuitive science experiments that require little more than common household items and a sense of curiosity. Prepare to have your surprise sensors on overload as Neil Downie stretches math, physics, and chemistry to do what they have never done before. This book describes twenty-nine unusual but practical experiments, detailing how they are done and the math and physics behind them. It will delight both casual and inveterate tinkerers. Of varying levels of complexity, the experiments are grouped in sections covering a wide field of physics and the borders of chemistry, ranging from dynamic mechanics (''''Kinetic Curiosities'''') to electricity (''''Antediluvian Electronics'''') and combustion (''''Infernal Inventions''''). The chapters are titillatingly titled, from ''''Twisted Sinews'''' and ''''Mole Radio'''' to ''''A Symphony of Siphons'''' and ''''Tornado Transistor.'''' More-detailed explanations, along with simple mathematical models using high-school level math, are given in boxes accompanying each experiment. Armchair scientists will welcome this edifying and entertaining alternative to idleness, not least for the buoyant prose, enriched by historical and literary anecdotes introducing each topic. With this book in hand, tinkerers, whether dabblers in science or devotees, students or teachers, need never again wonder how to impress friends, the judges at the science fair, and, not least, themselves.

The Pandemic Paradox - Scott Fulford - Bog - Princeton University Press - Plusbog.dk

Why most Americans’ finances improved during the worst economic contraction since the Great Depression—and the policy choices that made this possible In March 2020, economic and social life across the United States came to an abrupt halt as the country tried to slow the spread of COVID-19. In the worst economic contraction since the Great Depression, twenty-two million people lost their jobs between mid-March and mid-April of 2020. And yet somehow the finances of most Americans improved during the pandemic—savings went up, debts went down, and fewer people had trouble paying their bills. In The Pandemic Paradox , economist Scott Fulford explains this seeming contradiction, describing how the pandemic reshaped the American economy. As Americans grappled with remote work, “essential” work, and closed schools, three massive pandemic relief bills, starting with the CARES Act on March 27, 2020, managed to protect many of America’s most vulnerable.Fulford draws from the Consumer Financial Protection Bureau''s “Making Ends Meet” surveys—which he helped design—to interweave macroeconomic trends in spending, saving, and debt with stories of individual Americans’ economic lives during the pandemic. We meet Winona, who quit her job to take care of her children; Marvin, who retired early and worried that his savings wouldn’t last; Lisa, whose expenses went up after her grown kids (and their dog) moved back home; and many others. What the statistics and the stories show, Fulford argues, is that a better, fairer, more productive economy is still possible. The success of pandemic relief policy proves that Americans’ economic fragility is not an unsolvable problem. But we have to choose to solve it.
