#OTD in 1843.

William Rowan Hamilton invents quaternions, a 3D system of complex numbers.

Important precursors to this work included Euler's four-square identity (1748) & Olinde Rodrigues' parameterization of general rotations by 4 parameters (1840), but neither of these writers treated the four-parameter rotations as an algebra. Carl Friedrich Gauss had discovered quaternions in 1819, but this work was not published until 1900.

Portrait of Sir William Rowan Hamilton. In the image, Hamilton is shown as a mature man with a thoughtful, introspective demeanor. His face is marked by high cheekbones, a prominent brow, and deep-set eyes that reflect intellectual depth. His hair, typically dark and wavy, is styled neatly, though in some versions of his portraits it appears slightly receding, signaling the passage of time. His expression is serious, with a slight furrow in his brow, indicative of his deep intellectual pursuits.

Not so short note on aria-label usage – Big Table Edition

“aria-label is one of a number of secondary methods to label native HTML UI elements. It works particularly well on interactive elements, it also works well on most block level elements old skoolterm that have explicitly or implicitly defined structural roles. It works less well or not at all on text level semantics.”

„Naposledy za námi přijela někdy na podzim. Jen na pár dní. Ustlala si tehdy mezi mnou a klukem, na zemi, přímo pod stolem. Prý že tak je zvyklá, že takhle se cítí v bezpečí. Celé noci tam pak naříkala. Vyla jako zvíře a křičela ze spaní. Nikdo si prý neumíme představit, co se tam na východě odehrává.“

Ever find that sitting in front of your unnecessarily complex music rig is hard sometimes? Creative block hits and there's nothing you can do about it?
I certainly find that lately, more often than not.
One device has come into my life and changed a lot of that however. Ableton Move.

In this world-first video, I take you through making a beat without sight, just using the undocumented screen-reader function within the web-based Move Manager.

It's incredibly freeing to be able to just load a fresh set, be presented with four random sounds and perhaps one of them will inspire you so you just begin doing a thing that you had absolutely no plan to do before you started.

[EN]Since new readers have arrived here, I think I should introduce myself again. My name is Berta, I am a Spanish-Ecuadorian #philosopher and #artist. I am especially interested in the transition from #nature to #cultures, #mythology, #religion, and #symbolism. In my current #photography project, I am reconstructing the myth of Persephone.

Now this is something I want. Don't get me wrong, I love my cane but if there's anything I can use to make traveling easier, you best believe I'm using it because right now, its just so exhausting to even want to walk anywhere and I'm tired after going out. It's much less exhausting being driven anywhere so if I can make walking easier with this cane, I'd get it. #Blind

If you are using a so called smart connected TV and are concerned about your privacy, you should read the following scientific article: "Watching TV with the Second-Party: A First Look at Automatic Content Recognition Tracking in Smart TVs"
arxiv.org/pdf/2409.06203v1

In short, if your TV's settings are not correctly adjusted, it can periodically (in some cases, every 10 seconds) send a fingerprint of what is being displayed to a server to find out what you are watching.
