You sly dawg

It took me up until reading your comment to get this one. "Is it that the scaling transformation only scaled the y-axis?? Oh..."

[–] radicalautonomy@lemmy.world 16 points 4 months ago (1 children)

I teach these basic transformations as part of my middle school math classes, and I was completely loss as to why they didn't include a reflection, but then I realized a reflection wouldn't be that interesting because it could be indistinguishable from a translation.

I was at a loss too as to where they source the "most common" when skewing is also extremely common

[–] radicalautonomy@lemmy.world 4 points 4 months ago* (last edited 4 months ago) (1 children)

Scaling, in general, is the least common middle school transformation covered by state curriculum as far as depth of knowledge is concerned, at least where I've taught. Students just aren't ready at that age to calculate something as sophisticated as the scale factor contributing to an object's loss of size.

[–] untorquer@lemmy.world 2 points 4 months ago (1 children)

I think the students are ready and quite capable of such sophistication. They're just too distracted with sharing memes.

(Oh, I know, my middle schoolers do alright as long as our figures are two-dimensional, and my high school geometry students do very well; I just wanted to say the magic, fun, wink wink word again. 🙂)

Don't use this. It's not a lossless transformation!

Meanwhile, in SVG: <g filter="scale: 0.5"><xlink:use … /></g>

[–] magnetosphere@fedia.io 57 points 4 months ago (3 children)

Goddammit. This is like getting rickrolled.

[–] ICastFist@programming.dev 25 points 4 months ago

We rarely get rickrolled anymore, such a loss

Is this science?

...seriously, I'm at a loss

[–] justme@lemmy.dbzer0.com 23 points 4 months ago (1 children)

The second is not really scaled, and the second and forth have translation. Usually that wouldn't be a problem for demonstrative proposed, if translation wouldn't be shown explicitly. Can be fixed by introducing a canvas of the before/after picture

[–] jol@discuss.tchncs.de 7 points 4 months ago

The second is scaled in one axis, and had translation otherwise it would be hard to understand. And the rotation can be achieved by moving the origin of rotation.

Ok ... I didn't know this meme (too old and/or out of the loop I suppose) ... so out of annoyance I looked it up ...

... and yea ... as far as trolling is concerned gotta pay the game here ... not sure it was worth 15 mins of my life but ... kudos I guess

Scaling looks like scaling+translation? And rotation looks like either rotation+translation, or scaling+translation?

What is “loss” in this context?

[–] flyingchaucer@lemmy.sdf.org 29 points 4 months ago (1 children)

Know Your Meme's page on Loss.

Basically, a 2000s webcomic about gamer culture devoted a comic (titled Loss) to the writer's partner who had a miscarriage. It's four wordless panels, and the characters in each panel take up roughly the positions of the rectangles in the OP.

Tonally, it was the complete opposite of what the webcomic normally covered, and it really shocked its readers who, being an internet community, responded with irony and parody, and now there are a ton of Loss references out there.

Only the transformations one is correct. All the other ones seemingly also preform a translation, and even if they might be correct if you take the orgin to be slightly outside of the shape but that's bad for educational purposes. Also this one makes the translation transformation look like the identity transformation.

This last one might just be me, but shouldn't shearing be included here?

[–] Maalus@lemmy.world 10 points 4 months ago (1 children)
[–] Hjalamanger@feddit.nu 1 points 4 months ago (1 children)

Could you explain it then?

[–] KillerTofu@lemmy.world 4 points 4 months ago

It’s a “loss” meme.

[–] GlennMagusHarvey@mander.xyz 9 points 4 months ago

Um

The second wrong.

Or...only one

[–] einlander@lemmy.world 8 points 4 months ago (1 children)

No shear is disappointing.

[–] half_built_pyramids@lemmy.world 20 points 4 months ago

Yeah, such a big loss it wasn't included.

[–] funbreaker@lemmy.zip 6 points 4 months ago

I had to look at this twice to get it. I must be losing my touch.
