Imagine pouring together two cups of warm water and somehow ending up with a cup of boiling water. That cannot happen in everyday life, but at the quantum level, something similar is possible. Multiple low-energy particles of light can combine their energy to create a single particle with much higher energy.
The Toyota Corolla is the ubiquitous small car. Over the course of its 58 years on sale in the United States, it has earned itself a widespread reputation for being supremely dependable, efficient, and affordable, but typically devoid of engaging driving dynamics or any other exciting qualities. (Unless, of course, there are a few extra letters tacked on like GR, and the old AE86 is another story too.)
Ferraris and Lamborghinis might be sought after, but they're not exactly rare. Neither are Porsches, or Lotuses, or McLarens or Ford GTs. Do you know what is really rare, though? The Smart Crossblade. Mercedes-Benz had the wherewithal to build just 2,000 of these bizarre little roadster things for the entire world between 2002 and 2003, and there's really no way to know how many have made it over to the U.S., as it was never officially sold here. If I had to guess, there are fewer than a dozen. So, when I saw there was one sitting at Vantage Auto, a dealership just 15 miles outside Manhattan (and less than a mile away from the house I grew up in), I knew what I had to do. I had to call these people up and ask them very nicely if I could get behind the wheel of their very rare little car.
One desktop computer sat in the back of the room, usually reserved for Accelerated Reader quizzes, and a computer lab down the hall hosted weekly keyboarding lessons. When laptop carts arrived, it felt like the future had rolled in on wheels.
Only about one in three students say their school has a school-wide AI policy, yet students across the country are already using AI to complete assignments, study for exams, and make decisions about their daily lives. Aleta Margolis, founder and president of the Center for Inspired Teaching, has spent three decades coaching teachers to ask better questions and listen more carefully to students. She argues in a recent EdSurge piece that the policy conversation cannot come first: the human conversation has to.
When Logan first drove the Mercedes-Benz CLE300, he didn't quite fall in love with it, and Amber didn't like the CLE she drove either. Normally, I wouldn't have a problem with that, but in this case, it's Mercedes. Luxury coupes and convertibles are Mercedes' thing. Plus, Logan is nine feet tall, and Amber lives in New York City. Maybe the CLEs they drove were just the wrong cars for them. Surely I, a proper grand touring appreciator, just needed the right CLE and the right road trip, and I'd be singing the new tweener two-door's praises until everyone started to get annoyed with it.

When Lexus first launched as a brand in 1989, it offered two sedans: the ES and the LS. The full-size LS flagship quickly came to define the Lexus ethos, but 37 years later, it's the mid-size ES nameplate that persists. Lexus is going back to having just two sedans, and the LS will not be one of them, as it's bidding farewell with just a 250-unit run of Heritage Edition models for 2026. The compact IS is still around, but it's getting long in the tooth as the third generation has just received its third facelift.
