I'm creating an app that explains special relativity with interactive 3D spacetime models, for Apple Vision Pro, iPhone and iPad

Pinned

Relativity for Earth People is an app for everyone who wants to gain an intuitive understanding of Einstein's theory of special relativity but doesn't have the time or patience to work through the math. More details: lunarskydiving.com/relativity/ #AppleVisionPro #VisionPro #visionOS


We don't have anything to fear from AI's problem solving abilities until it develops the ability to take showers or go on long walks.

We shall measure stellar brightness logarithmically, and it will be called the "magnitude." - Sir, will that logarithm be base 10, or based on Napier's constant? Neither. It shall be of the base of the fifth root of one hundred.

The easiest way to see that gravity is not a force is to note that a force causes acceleration, but gravity does not. Acceleration is measurable with a device called an accelerometer. Acceleration is not relative (like velocity), it's absolute. If you are standing on the…

New in iOS 17.5 is UIImpactFeedbackGenerator/impactOccurred(at:), which allegedly generates haptic feedback at a specific screen location. developer.apple.com/documentation/… Which devices support this? How does this work if the haptic feedback unit has a fixed location?

shader programming is for when off-by-1 errors just aren't doing it for you anymore, and you're looking to get into new things like • off by 1/2 • off by multiple of -1 • off by power of 2 • off by a reflection around 1/2 • off by 1 graphics api


If I extrapolate Swift’s trajectory, it will become as complex and crufty as C++ sometime in 2029.
