The Great Pyramid of Giza might be the most iconic structure humans ever built. Ancient civilizations constructed archaeological icons that are a testament to their greatness and persistence. But in some respects, the Great Pyramid stands alone. Of the Seven Wonders of the Ancient World, only the Great Pyramid stands relatively intact.

A team of scientists will use advances in High Energy Physics (HIP) to scan the Great Pyramid of Khufu at Giza with cosmic-ray muons. They want to see deeper into the Great Pyramid than ever before and map its internal structure. The effort is called the Explore the Great Pyramid (EGP) mission.

The Great Pyramid of Giza has stood since the 26th century BC. It’s the tomb of the Pharoah Khufu, also known as Cheops. Construction took about 27 years, and it was built with about 2.3 million blocks of stone—a combination of limestone and granite—weighing in at about 6 million tons. For over 3,800 years, it was the tallest human-made structure in the world. We see now only the underlying core structure of the Great Pyramid. The smooth white limestone casing was removed over time.

For almost a century, we’ve been intrigued and sometimes terrified by the big questions of artificial intelligence. Will computers ever become truly intelligent? Will the time come when machines can operate without human intervention? What would happen if a machine developed a conscience?

In this episode of Perspectives, six experts in the fields of robotics, sci-fi, and philosophy discuss breakthroughs in the development of AI that are both good, as well as a bit worrisome.

Clips in this video are from the following series on Wondrium:

Mind-Body Philosophy, presented by Patrick Grim.

If you’ve studied any physics you know that like charges repel and opposite charges attract. But why? It’s as though this thing — electric charge — is as fundamental a property of an object as its mass. It just sort of… is. Well it turns out if you dig deep enough, the fundamental-ness of charge unravels, and in many things, including mass itself, are unraveled with it.

Koenigsegg calls the engine the Tiny Friendly Giant, or TFG for short, and it’s an apt name. The TFG is a 2.0-liter twin-turbo three-cylinder that makes 600 horsepower. At 300 horsepower per liter, the TFG’s specific output is far higher than anything ever seen in a road car. Koenigsegg says this is “light-years ahead of any other production three-cylinder today,” and he’s not wrong: The next most powerful triple is the 268-hp engine in the Toyota GR Yaris.

What’s even more unusual is that the TFG doesn’t have a camshaft. Instead, the engine uses technology from Koenigsegg’s sister company, Freevalve, with pneumatic actuators opening and closing each valve independently. I called company founder Christian von Koenigsegg to learn exactly how this unconventional engine works.

The Tiny Friendly Giant was designed specifically for the Gemera. Koenigsegg wanted something compact and lightweight, with big horsepower. Koenigsegg also decided to reverse the setup found in the hybrid Regera, where internal combustion provides the bulk of the total power output. In the Gemera, the majority of the power comes from electric motors, with the Gemera contributing some driving force as well as charging the hybrid drivetrain’s batteries.

The “Tiny Friendly Giant” is a game-changer for internal combustion. Christian von Koenigsegg explains this camless wonder.
