Editorial
Our debt and indebtedness to science When the U.S. President and the Speaker of the House worked out a deal last month to suspend the country’s $31.4 trillion debt limit through January 2025, they averted a seismic default that many agreed would have caused catastrophic volatility in global financial markets. That’s the good news. The bad news — at least for many readers of this magazine — is that both...

Da Vinci’s Mona Lisa gets a holographic makeover When Leonardo da Vinci immortalized Lisa del Giocondo with his portrait of her in 1503, he created her famously subtle smile and lifelike flesh by using deliberately irregular brushstrokes. His masterpiece, the “Mona Lisa,” not only became one of the most familiar images in history, but it also created a study of light that seemed impossible for any painter to improve upon. Five hundred years...
