It’s that time of year again – time for baseball, heading to your favorite vacation spot, relaxing ... and sitting in an air-conditioned theater watching that summer blockbuster everyone can’t stop talking about. Will this summer’s great flick be the “Space Jam” sequel The “Black Widow” movie delayed from last summer? Or the musical “In the Heights”? Let’s go see ’em all, just in case ...

Seventy-five years ago today, the United States tested an atomic bomb on a tiny island in the Pacific Ocean. It was the world’s fourth atomic explosion – after the first test in New Mexico in August 1945 and then the bombs that were dropped on Hiroshima and Nagasaki. But Operation Crossroads kicked off an era of high-stakes nuclear proliferation and Cold War one-upmanship.

Resorts World Las Vegas opened Thursday featuring more than 3,500 guest rooms and suites via three Hilton hotels, a mammoth casino, 100,000 square feet of nightclubs, restaurants, retail stores, a spa and a 5,000-seat concert venue. Here’s a look at what guests will find there:

Here’s your “do you feel old yet?” moment for today: The original “Willy Wonka and the Chocolate Factory” movie starring Gene Wilder was released a halfcentury ago Wednesday. To celebrate, here are 12 things you might not have known about Willy, his little pal Charlie Bucket and Willy’s Oompa Loompa work force.

While others were working on computing machines before Alan Turing’s heyday before and during World War II, Turing was one of the first to consider computers more than just souped-up calculating machines and more of a way of solving real human problems.

Five years ago Wednesday, the British people shocked the world and the European community – and a large part of themselves – by voting to leave the European Union. What came to be called Brexit would take four years to pull o and, even now, there are still aspects of the union that have yet to be dissolved.

Thirty years ago this week, Sonic the Hedgehog made his debut – or, at least, he did for gamers who used the Sega Genesis as opposed to the brand-new Super Nintendo. And 40 years ago next month, Donkey Kong first appeared in video games around the world. The result of all this would be an awful lot of gaming fun.

Growing up in the 1970s, I became fascinated with what appeared to be a wonderfully creative field: Rock and roll album cover design. Some album covers featured photos of the artist. Some used abstract art. Some were amusing. Some were deadly serious. They all had one thing in common, though: To entice a music buyer into picking up the album and then buying it. Which brings up the question: How on Earth did any of these albums sell a single copy?

In America, it was called Jim Crow. In South Africa, the term was apartheid: strict racial segregation enforced by law that began in the late 1940s and early 1950s and didn’t end until, under tremendous pressure from the international community, South African leaders decided apartheid had to go. That happened on June 17, 1991: Thirty years ago today.

Last month, Phil Mickelson stunned the golf world by winning the PGA Championship at Kiawah Island, South Carolina – the oldest golfer to win a major tournament. Today, Mickelson turns 51.

Thirty years ago today, Mount Pinatubo – a peaceful unassuming mountain 50 miles northwest of Manila in the Philippines, erupted in what would be the second-largest volcanic event of the 20th century.

Seventy years ago today, the first electronic computer built specifically for commercial purposes was put to use by the customer that bought it: the U.S. Census Bureau.

Fifty years ago Sunday, the New York Times began publishing a series of reports culled from a top-secret analysis compiled for the Pentagon regarding the true extent of U.S. involvement in Vietnam and in the Vietnam War. The report embarrassed a number of career politicians and leaders. At one point, the series would be shut down for 15 days by a court order.

Forty years ago Saturday, two of America’s most beloved filmmakers – George Lucas and Steven Spielberg – teamed up to revive a style of action film that hadn’t been in vogue since before World War II. Instead of a secret agent or a private detective, the hero was a college professor and archaeologist. And he wasn’t after riches or revenge or a way to travel in space. He hunted for objects to put in a museum.

Fifty years ago next week, master songwriter Carole King – who had released her classic solo album “Tapestry” earlier that year – gave her first concert performance in front of a live audience at New York’s Carnegie Hall. That show would be well-received – and, in fact, would be released on CD a quarter-century later. But in order to truly understand King and her work, you need to also consider her songwriting output for other artists in the 1960s.

On this date 40 years ago, the Irish band U2 made its national TV debut in the U.S. on Tom Snyder’s late-night talk show, “Tomorrow.” For many of us, it was our first look at what would soon become one of the biggest acts in rock.

125 years ago Friday, Henry Ford introduced what he called a Quadricycle – an early automobile. It didn’t have a steering wheel or rear-view mirrors or turn signals or Bluetooth so he could connect his audio system to his smartphone. Still, his Quadricycle and its descendants would profoundly impact the lives of every American.

Forty years ago Saturday, the Centers for Disease Control and Prevention released a report on a lung condition found in previously healthy gay men in Los Angeles over the previous months. This paralleled growing rumors of a “gay cancer” that was quietly spreading through the gay communities in New York and San Francisco. Acquired Immunodeficiency Syndrome – or AIDS – didn’t yet have a name. But it would soon become a household word.

Avista – known once upon a time as the Washington Water Power Company – announced last week it was selling the Central Steam Plant it bought 102 years ago to a local developer. Over the past century, the plant went from being a source of heat and electricity for downtown residents and businesses to a high tech commercial and dining hub and an icon of the Spokane skyline.
