❗ 💡 ⭐ hi all, the 3rd black hole merger capture by LIGO was announced within the last week. a huge deal![f] have been tracking this area. its a “ringing/ rippling” excitement in physics and cosmology, its like christmas and even conservative scientists are talking in profound terms. a new detector is going online soon in europe (named Virgo in Pisa, Italy)[f11] and there are predictions that up to about 1 event per day may be observable after all the machines are finetuned!
☯️ this all coincides with a lot of theoretical commotion at the same time. ofc as long observed here, experiment and theory are like yang+yin, each energeizes and contains elements of the other, so to speak. its well/ widely acknowledged that GR+QM unification is a/ the big/ key open question of physics and there are a lot of new ideas circulating, and anything to do with gravity is nearly by defn highly coupled with GR.[b] this also ties in with new theories about big bang/ expansion.[e] theres some big contention going on.
am esp interested in Verlindes ideas about gravity as an “emergent phenomenon” that possibly is a solution to the “dark matter” problem.[c] have been promoting this rough conceptual idea myself for many years and feel it ties in naturally with pilot wave hydrodynamics and soliton dynamics (latest big writeup on that only ~½ yr ago). in short, an image to ponder: a wave-particle seems to continuously emanate waves out to infinity. what effect do those have collectively? is there some emergent property there?
in contrast to sometimes having no idea about future directions with these posts, the last blog gave some excellent themes/ ideas for research directions and this new post. to put it in the vernacular, am finally really on a roll! aka/ reminds me of “hot hand!” and yet also lately feeling really strong flow in more ways than 1! 😮 😀
hi all Google Deepmind has pulled another rabbit out of the hat and won 3-0 against the worlds reigning Go champion Ke Jie who coincidentally is also Chinese, only about 1yr since last historic match.[a] the 19year old was reportedly literally in tears.[a17] quite a different reaction than kasparov ~2 decades ago! looks like emotions really run the gamut eh? last years match with Lee Sedol had him apologizing for/ to humanity at the end! reminds me of the so-called “5 stages of grief” concept from psychology… where the “loss” is one of mankinds most priceless/ treasured possessions, its uniqueness wrt intelligence/ mind!
theres a brand new AlphaGo movie/ documentary on the prior history, cant wait to see it, has anyone else?[a8] what do you think? how does google/ deepmind top this? apparently they cant and actually theyve announced theyve decided to avoid any further human media/ spectacle matches! or is that just my interpretation? Hassibis is quoted as saying AlphaGo will stop/ retire, but not sure exactly what he means by that, its a big question mark, and the funky/ choppy chinese translation certainly isnt helping any.[a17] doesnt it make some sense to continue to refine it some, or release parts or all of it, do some maintenance, etc? it seems even after it beats the top human there is some small )( suspense left. (have always thought it a bit of a historical loss verging on tragedy that IBM Deep Blue chess hardware/ code was “decommissioned” and maybe never archived or released to the public.)
various alignments and massive themes going on here. the Chinese have funneled billions of dollars into AI research and yet this match was not really publicized much or celebrated within china, in stark contrast to last years international Korean media extravaganza, verging on near-media-circus! the state censorship system apparently decided to cut off the live feed of the match ~30m into it after uncertain/ unknown reasons, and/ or it became clear that maybe their human player would not dominate. and then theres the trickiness of Google having withdrawn from china in the prior few years due to their hacking, and wanting back into the gargantuan market. but oops! chinas semi-state-sponsored companies compete directly with google services. as the teenagers say, AWKWARD! 😳
hi all the chip and hardware news has been very active lately. years ago tracked AI/ big data as separate categories and these two areas are merging. AI + hardware design is merging these days also. this is typified/ exemplified by googles new announcement of TPU (tensorflow processor) chips that they have designed themselves.[a] google is intending to scale up this architecture for open use. its an impressive initiative in its early stages and highly crosspollinates with its other big moves into AI such as with Deepmind.
elsewhere there is a lot of news about “brainlike chips” being developed. these may be massively parallel or based on “neuromorphic” computing.[b]
as was noted/ heralded on this blog quite awhile back, moores law is now widely questioned and suspected to be plateauing.[c]
💡 ❗ ⭐ this code has a lot of moving parts and took quite awhile but is also a culmination of many previous ideas. it has the same distribution generation mechanism as last run (slightly modified/ adjusted), but its a 1st cut on evaluating the significance/ accuracy of the MDE/RR model as a predictor of trajectory length. the better the accuracy of its modelling, the more “plausible” a (“analytic”!) model it is and viable for exploiting for further derivations.
