Fun Fact: Diffractive optics exhibit chromatic aberration in the opposite direction to Refractive optics, so the two can be used together to cancel each other out!
Of course, that doesn’t help with the weight on a space-based telescope, but it was being considered quite frequently for VR Headsets a few years ago.
It can do dense translation, translation + rotation, Affine, and Homography alignment; I've used it in the past to do sub-pixel Aruco/AprilTag alignment (and I'd probably also use it for astrophotography).
Are you kidding? If someone really has good evidence for the Earth being flat, that could potentially be one of the most important observations of all time!
As the Litany of Tarski goes:
“If the Earth is flat, I desire to believe the Earth is flat…” etc.
(Though, I will admit that it gets boring later when you’ve heard all the arguments and rebuttals.)
Since the train only shakes side to side (and not up-down or forwards-backwards), you only really need spring dampening along one axis.
While you could set up a linear rail with some pretensioned bungie cables (similar to how the Hover Glide backpacks work), I’d recommend using parallel leaf springs as they’re lightweight, low-form factor, mechanically simple, and low stiffness.
The key to supporting human weight is to replace the thin plastic leaf springs with sheet metal. You can also add more springs in parallel (increasing the weight it can support, but reducing the travel).
While they might be linked, I find it difficult to believe modern males have lower testosterone than pre-80’s females (which I’d expect if simply “Low-T” was causing the current surge in obesity in both genders).
It’s possible the threshold (where Testosterone is converted to Estrogen) is lowering, and both fat deposition and other things are all downstream effects of phthalates.
However it’s just as likely that this is due to antibiotic-contamination in food changing our gut flora, or Pesticides/Lithium/PFAS/High-Fructose-Corn-Syrup/EM-Radiation/Elevation are messing with our homeostatic equilibrium in other ways…
It would be interesting to find a study that controlled for each of these factors to find the strongest correlates.
Another interesting clue to add to a growing body of evidence that the obesity epidemic is due to an unidentified environmental contaminant and not explicit changes to diet or “discipline”:

Even worse, two parties with animosity against each other will rank each other at the bottom of stack, allowing the generally amicable independents to sweep the election. It’s the perfect way to incentivize depolarization.
Everything in BotW has that formulaic/modular/cookie-cutter feel that a Bethesda game does. None of the side quests particularly stood out to me, whereas I’ll frequently recall hidden gem areas in OoT and Wind Waker with fondness.
It’s clear that it was a game that was produced highly in parallel, with independent parallel teams (of interns?) and obscene levels of modular asset reuse. Exploration is often rewarded with a cookie-cutter item, or (even worse) a Korok seed rather than an expansion of the lore or new stories.
Many of the things I hate about procedurally generated games or the recent spate of mass production open world games (ie Genshin Impact) are present in BotW.
On the opposite end of the spectrum are games like Dark Souls, with relatively little asset reuse and great lore-expanding rewards for exploration.
Hi HN, I've been working on this tool for the last couple of months, and I feel like you guys might appreciate it.
I love OpenSCAD, but it's showing it's age. So I decided to build a luxury version with VS Code's Editor (with Intellisense!) and a WebAssembly-port of OpenCASCADE (the same BREP CAD Kernel in FreeCAD and CadQuery). Everything is client-side, from the model compilation to the deflate-encoded shareable URLs. You can even install the editor to your computer (or even Chromebook!)
Given the recent news from Autodesk making everyone skittish about the future mobility of their .STEP files, I figure that CascadeStudio can provide another place for people to edit and share their 3D Models and BREP designs.
Of course, that doesn’t help with the weight on a space-based telescope, but it was being considered quite frequently for VR Headsets a few years ago.
