Why is the sky blue?
The internet’s default answer to “why is the sky blue?” is “Rayleigh scattering”. And that’s not wrong, but it’s also not very useful. Simply knowing the name of something is very different from understanding it. But if names don’t constitute understanding… what does? My answer: having a model that allows you to make predictions. If you can reliably predict something, then you probably understand that thing. In this article, we’ll explore why the sky is blue – but we’ll go deep enough that, by the time you finish, you can predict what color the sky will be on other planets.

Project MUSE – The Perception of Qualities in Typefaces: A Data Review
The current review aims to provide professionals with scientific support for choosing an appropriate typeface by collecting scattered data in a single place. We describe the findings of 34 studies that asked participants to rate the perception of 229 qualities in 635 typefaces, and we created a unified dataset where data are easily comparable across multiple studies. We believe this work will make the messages created by professionals in the design, marketing and communication industries more effective.

Babylon 5 Is Now Free to Watch On YouTube | Cord Cutters News
nI a move that has delighted fans of classic science fiction, Warner Bros. Discovery has begun uploading full episodes of the iconic series Babylon 5 to YouTube, providing free access to the show just as it departs from the ad-supported streaming platform Tubi. The transition comes at a pivotal time for the series, which has maintained a dedicated following since its original run in the 1990s. Viewers noticed notifications on Tubi indicating that all five seasons would no longer be available after February 10, 2026, effectively removing one of the most accessible free streaming options for the space opera. With this shift, Warner Bros. Discovery appears to be steering the property toward its own digital ecosystem, leveraging YouTube’s vast audience to reintroduce the show to both longtime enthusiasts and a new generation.
Free Streaming One Little Pill (documentary film)
"Your alcoholism will kill you before your HIV does,” says a doctor to one of our characters. Worldwide, alcohol abuse kills more people than HIV, nearly 3.3 million per year. Yet what the public believes, and Alcoholics Anonymous purports, “Once an alcoholic, always an alcoholic,” is not as true as you think. Nor is the fundamental principle for treating alcoholism that we all take as truth; abstinence. Science has shown that abstinence not only doesn’t take away the addiction, but also increases the craving. So why has one modality dominated our thought since the 1930’s? Why are profitable rehab facilities reluctant to change? And why are millions of people still being denied the opportunity of a simple life saving method and drug that have been FDA approved since 1994? One Little Pill takes an in depth look at a simple, safe method with success rates of 78%, the suppressing obstacles surrounding it, and those people just now finding it. This character driven film will leave you compelled to help spread the word that "Options Save Lives."

Why Federated Design Systems Keep Failing
I spent nine years at Spotify leading design systems and accessibility. During that time, I learned as much from what failed as from what succeeded. I'm sharing these insights not to critique decisions made at the time, but because I believe they're valuable and can help others navigate similar challenges. This is the first in a series exploring those lessons.
