@vonxylofon but when I wear a watch (which is every day), and my train leaves at 18h, I don’t want to have to do math while looking at my watch to see if I’m going to be on time or not.
@zed @vonxylofon “Have to do the math”?! HAHA!
Oh, sorry, you say math as singular not maths as plural. I apologise for your education system. I’ll speak slowly from now on.

@WTL @Natasha_Jay @renchap I’ve never understood the U.S. obsession with getting it wrong. It’s not even simple to sort by date.
@Wen @WTL @Natasha_Jay @renchap
Half-assed guess: it came, or at least got more firmly entrenched, when US English stopped referring to dates as something like “the 19th of January, 2026” and started using “January 19, 2026” instead. The older form is still around, but outside of fixed expressions like “the 4th of July” for US Independence Day, it’s decidedly old-fashioned and not common anymore.
“1/19/2026” is a crappy way to write this from a numeric perspective, but it is a pretty direct transcription of the verbal date format into numbers.

@pms @Natasha_Jay @bsdphk One I specifically want abandoned is comma as thousand separator, as otherwise it would be just non-breakable space as thousands separators, and either dot or comma as decimal separator.
Although could also use units as separator, like done with height (1m60) and time (1h30m)@lanodan @pms @bsdphk @Natasha_Jay In Indian Subcontinent , we use Lakh, Crore instead of millions and billions. So instead of 1,000,000,000.00, we write 100,00,00,000.00

>the primary cause of the failure with the Hubble Space Telescope's mirror was spherical aberration caused by a miscalibrated, faulty testing device during manufacturing.
Here are the key details regarding the failure as discussed by users:
The Root Cause (The "Why"): The primary mirror was ground and polished by Perkin-Elmer to the wrong shape because a device called a "null corrector"—used to measure the mirror's surface during polishing—was assembled incorrectly.
The Specific Error: A spacing error of 1.3 millimeters in the null corrector (caused by a missing cap on a rod) led to the mirror being polished too flat at the edges by roughly 2.2 microns (1/50th the width of a human hair).
Ignoring Data: Users noted that a second, independent testing device actually indicated the mirror was flawed, but this data was ignored because the, albeit faulty, "new" null corrector was trusted more.
The Fix: Because the mirror was ground so accurately (just wrongly), scientists knew exactly how to fix it. The 1993 servicing mission (STS-61) installed COSTAR (Corrective Optics Space Telescope Axial Replacement), which acted as "glasses" to correct the aberration.
>One report explained it this way;
If you took a finely polished mirror and enlarged it to the size of the Gulf of Mexico, you'd have a surface with +/- 80 foot swells.
If you enlarged the Hubble mirror to the same scale, you'd have a surface with +/- 3 inch swells.
>Imagine you are trying to make a perfectly shaped, giant, curved mirror for a space telescope (like Hubble). Because it’s so large, you need to check if you are grinding the glass into the exact right shape.
The Problem: The mirror is a weird shape (aspheric). If you shine a light on it to check the shape, the light bounces back looking crazy and blurry. You can’t tell if the mirror is wrong, or if it just looks that way because of the weird curve.
The Solution (The Null Corrector): You put a special lens or mirror between your eye (or camera) and the giant mirror. This device takes the messy, distorted light and "fixes" it.
"Null" Means Zero Error: If the giant mirror is ground perfectly, the null corrector makes the reflected light look completely flat (or "null" of errors).
https://en.wikipedia.org/wiki/Null_corrector
>Why an Aspheric Shape is Needed
Spherical mirrors (like a perfect bowl) focus light from distant objects to different points depending on where the light hits the mirror, causing blur.
Aspheric mirrors, with a more complex curve, can focus all light rays to a single, sharp focal point, producing clearer images. Hubble's design used this superior shape.
@amiserabilist @wendinoakland @glasspusher @Natasha_Jay @stux fighting over the shape of a mirror vs. metric vs. imperial may be the most internet thing to happen.
Mastodon truly is Internet, but like… the 90s, yo.
