An engineering history of the Manhattan Project

The Manhattan Project, the US program to build an atomic bomb during WWII, is one of the most famous and widely known major government projects: a survey in 1999 ranked the dropping of the atomic bomb as the top news story of the 20th century. Virtually everyone knows that the project built the bombs that were dropped on Hiroshima and Nagasaki. And most of us probably know that the bomb was built by some of the world’s best physicists, working under Robert Oppenheimer at Los Alamos in New Mexico

Why basic science deserves our boldest investment

Inspired by the 1945 report “Science: The Endless Frontier,” authored by Vannevar Bush at the request of President Truman, the US government began a long-standing tradition of investing in basic research. These investments have paid steady dividends across many scientific domains—from nuclear energy to lasers, and from medical technologies to artificial intelligence.

This ‘Magical’ Material That Dissolves Like Candy Is Exactly What EVs Have Been Missing

The irony of eco-friendly electric vehicles is the mountainous load of electronic waste they produce. So far, most targeted efforts to recycle EV batteries have been expensive and chemically toxic—and they haven’t stuck. That could change soon, however, thanks to a promising breakthrough from MIT.

Solar-Powered Device Turns Moon Dirt Into Bricks, a Potential Breakthrough in Lunar Construction

Both the U.S. and China have set their sights on the Moon, aiming to break ground on permanent lunar bases within the next decade. Though there’s no legal basis for claiming territory in space, whichever country gets there first will gain a coveted first-mover advantage, allowing it to set certain ground rules about who can do what, where. But getting there first is only half the battle. Actually establishing a sustained lunar presence presents significant logistical and engineering challenges.
