I found this surprisingly counter-intuitive: so-called “attention sinks” in #LLMs are actually a feature, not a bug.
Found this amazing paper on the topic: arxiv.org/pdf/2504.02732

Interesting piece by @quantamagazine.bsky.social on "Platonic Representation Hypothesis" (Neural networks, trained with different objectives on different data and modalities, are converging to as shared statistical model of reality in their representation spaces).

Arthur Eddington was born #OTD in 1882. He led an expedition to observe a Solar eclipse in 1919, which validated Einstein’s GR prediction of the deflection of light. The Eddington luminosity sets an upper limit to accretion.

Hubble has imaged the largest planet-forming disk ever seen! At 400 billion miles wide, it is roughly 40 times the diameter of our solar system. The disk is unexpectedly chaotic and turbulent, offering new insights into how planetary systems form: https://bit.ly/477sQ9b 🔭 🧪
Near the center is an object that resembles an edge-on view of a hamburger. There is a diagonal dark strip (the meat patty) of dust, running from 1 o’clock to 7 o’clock, that obscures a central star. Curving away from either side of the dark strip are glowing white clouds (the buns) where dust is reflecting starlight. Bright blue finger-like wisps of material extend far above and below the dark center plane. A few dozen stars, some with four diffraction spikes, are scattered on the black background of space.

Discovery of "Alaknanda": A massive, grand-design spiral galaxy found just 1.5 billion years after the Big Bang!

Found by Rashi Jain and Yogesh Wadadekar (NCRA-TIFR) using #JWST data. Its well-formed spiral arms challenge our understanding of how quickly galaxies settled into stable disks.

Every lens leaves a blur signature—a hidden fingerprint in every photo.

In our new #TPAMI paper, we show how to learn it fast (5 mins of capture!) with Lens Blur Fields ✨

With it, we can tell apart ‘identical’ phones by their optics, deblur images, and render realistic blurs.

Happy 120th birthday, special relativity!

Albert Einstein introduced special relativity in the paper "On The Electrodynamics Of Moving Bodies," published in Annalen der Physik #OTD in 1905. 🧪 ⚛️ 🔭

Manuscript: onlinelibrary.wiley.com/doi/abs/10.1...
English: www.fourmilab.ch/etexts/einst...
A black and white photo of Albert Einstein, around age 25, sitting at a desk. He is a wearing a flannel suit and resting his right arm on the desk. Einstein is looking to the left of the photographer in this posed photo. The first paragraph of the paper, in German. Translated to English is reads: It is known that Maxwell's electrodynamics—as usually understood at the present time—when applied to moving bodies, leads to asymmetries which do not appear to be inherent in the phenomena. Take, for example, the reciprocal electrodynamic action of a magnet and a conductor. The observable phenomenon here depends only on the relative motion of the conductor and the magnet, whereas the customary view draws a sharp distinction between the two cases in which either the one or the other of these bodies is in motion. For if the magnet is in motion and the conductor at rest, there arises in the neighbourhood of the magnet an electric field with a certain definite energy, producing a current at the places where parts of the conductor are situated. But if the magnet is stationary and the conductor in motion, no electric field arises in the neighbourhood of the magnet...

Paul Dirac was born #OTD in 1902. He is regarded as one of the most prominent theoretical physicists of the 20th century. The Dirac equation provides the first unified theory of quantum mechanics and special relativity.
