Finally, a cost estimate for building a real Death Star

Sometimes it seems the world is so screwed up we should just build a new one from scratch–and now we finally know how much such a project would cost.

In gloriously geeky fashion, economics students at Lehigh University tried to estimate how long it would take and how much it would cost to build the Empire’s ginormous man-made planetship if we were to get started today.

The students started by assuming the Death Star could be made from steel, and that the ship would be about as steel-dense as a modern warship, in particular the HMS Illustrious. Applying that steel density to the Death Star’s size–the moon-size weapon was reportedly 140 km in diameter–they determined that just over a quadrillion tons of steel (quadrillion comes after trillion) would be required for construction.

How MediaTek Optimizes SI Design with Cadence Optimality Explorer and Clarity 3D Solver

Sponsored by Cadence Design Systems

In the era of 5G/6G communication, signal integrity (SI) design considerations are important in high-speed interface design. MediaTek’s design process usually relies on human intuition, but with Cadence’s Optimality Intelligent System Explorer and Clarity 3D Solver, they’ve increased design productivity by 75X. The Optimality Explorer’s AI technology not only improves productivity, but also provides helpful insights and answers.
