Binoculars, an optical superpower through engineering - Ep 16
<p>A pair of binoculars might be the closest thing to a superpower you can buy. That is how a friend once described them while gifting a pair to his wife, and it is easy to see why.</p><p>In this episode of Rays and Waves, Daniel and Steven explore the surprisingly rich optical engineering behind binoculars. From magnification and aperture to prisms, coatings, and color performance, we follow the history of binoculars.</p><p>What seems simple is full of clever design trade‑offs. This episode connects everyday optics to fundamental engineering principles, revealing why small choices make a big difference in how we see the world.</p><p>If you enjoy the show, share it with your colleagues, subscribe, and leave us a review.

A space telescope architect’s odyssey from Hubble to Webb and beyond with Lee Feinberg - Ep 15
<p>From Hubble’s breathtaking images to the deep infrared view of the James Webb Space Telescope, space-based observatories have transformed how we see the universe. They reveal black holes, probe dark energy, trace the birth of stars, and even let us study the atmospheres of distant planets, pushing astronomy into entirely new territory.</p><p>In this episode of Rays and Waves, Daniel and Steven sit down with Lee Feinberg, a true veteran of space telescope engineering. Lee joined NASA during the Hubble era and played a key role in diagnosing and correcting its original optical flaw, helping restore one of the most important scientific instruments ever built.</p><p>Lee then went on to spend more than two decades on the James Webb Space Telescope as Optical Telescope Element Manager. We explore the critical decisions that shaped Webb, from selecting beryllium for its segmented primary mirror to developing new ways to test a deployable telescope at cryogenic temperatures, as well as the "cup up" optical test configuration that made full system testing possible on the ground.</p><p>This conversation dives into the optical engineering behind humanity’s most ambitious telescopes and what it takes to build instruments capable of looking back to the earliest moments of the universe.</p><p>If you enjoy the show, share it with your colleagues, subscribe, and leave us a review.

Project Silica and the future of data storage with James Clegg - Ep 14 - Rays and Waves
<p>In a quiet laboratory, bursts of ultrafast laser light are etching humanity’s information deep inside glass, layer by layer, voxel by voxel. Long after today’s hard drives and magnetic tapes have failed, this glass may still faithfully preserve our data, readable thousands of years into the future.</p><p>In this episode of Rays and Waves, Daniel and Steven dive into Microsoft Research’s Project Silica with their Senior Optical Engineer James Clegg. This is an ambitious effort to redefine cold data storage using focused femtosecond lasers. By writing information as sub‑micron, laser‑induced modifications to optical properties in hundreds of stacked layers, Project Silica turns glass into a truly three‑dimensional memory medium. These tiny structures are projected to remain stable for over 10,000 years and can be read out at any time using wide‑field microscopy combined with powerful machine‑learning algorithms.</p><p>Our conversation explores the physics behind laser‑matter interactions, the optical engineering challenges of writing and reading data in three dimensions, and what it takes to scale such a radical storage technology. We also discuss why long‑term archival storage matters, how this approach compares to traditional media, and what it means to build technology with millennia‑long time horizons.</p><p>Project Silica has been under development at Microsoft for nearly a decade, and the team recently published a comprehensive open‑access Nature paper detailing this remarkable achievement: <a href="https://www.nature.com/articles/s41586-025-10042-w" rel="ugc noopener noreferrer" target="_blank">https://www.nature.com/articles/s41586-025-10042-w</a></p><p>If you enjoy the show, share it with your colleagues, subscribe, and leave us a review!
