Mark “Superhero Copycat” Zuckerberg

A better world without Facebook and all its negative impacts would be a significant step forward. Facebook’s dominance and influence have often been associated with issues such as privacy breaches, the spread of misinformation, and the erosion of real social connections. By breaking free from Facebook’s grip, we can foster a healthier online environment that prioritizes privacy, genuine interactions, and reliable information. It is time to envision a world where social media platforms serve as catalysts for positive change, promoting authentic communication and meaningful connections among individuals.

Mark Zuckerberg, the co-founder of Facebook (now Meta), recently celebrated reaching 100 million users in just five days with his new Twitter-like platform called Threads. However, this achievement doesn’t impress me much. Instead, it highlights Zuckerberg’s tendency to imitate rather than innovate.

While I used to admire him, I now realize that he doesn’t belong in the same league as my true idols. Comparing the 100 million sign-ups for ChatGPT to the 100 million Threads users is simply absurd.

Advanced masking technology enables new applications for metasurface optics

Optics researchers at Lawrence Livermore National Laboratory (LLNL) have refined their novel metasurface process to create taller features without increasing feature-to-feature spacing, an advance that unlocks exciting new design possibilities.

“We have refined our process to create metasurfaces that allow for a wide optical bandwidth and a large span of incidence angles for an antireflection layer,” said LLNL research scientist Eyal Feigenbaum, the principal investigator. “We can now cover bandwidth range all the way from the ultraviolet to wavelengths larger than 2 microns, which is extraordinary. That wasn’t possible with the existing technology.”

The result is reported in a new paper, “All-Glass Metasurfaces for Ultra-Broadband and Large Acceptance Angle Antireflectivity: from Ultraviolet to Mid-Infrared.” It will be the cover story for the December 2023 issue of Advanced Optical Materials.
