<p>Michael Abrash's Graphics Programming Black Book is still one of my all time favourite. What they did back then was almost black magic. I learned a good part of maths, cs and physics trying to mod id1 with this book during my teenaghood.</p>

<p>Isn’t the very pitch ai bros have to their investors: “we’ll replace ppl by tokens.”<p>If it doesn’t pay for non-permanent staff salary that would be sad for the maths ppl indeed.<p>OTOH I have a phd in th physics, 15+ y of academic senior researcher experience, now working 60+ h /w on an unpaid internship and using lunch money to pay for tokens.<p>And I’m by far not most unlucky<p>Edit: just to put things in perspective, my phd field (string theory) has 15-30M€ annual funding in Europe (per google)</p>

<p>I have been moving from fusion 360/eagle to FreeCAD+Kicad for mixed electronic/mechanical designs and never looked back.  Since 1.0 assemblies work better in FC than 360, less crashes at least for my limited cases. Also an order of magnitude faster to boot. Didn’t have any issue with open cascade kernel, even with weird filets etc. Kicad is a joy to use compared to eagle, and library is even better.<p>Never tried OpenSCAD, maybe I’m old fashioned but graphic workflow works better for me.</p>

<p>Serious question: US spend 50+ B$ / month to throw JDAMs on little girls schools, what do we gain here?<p>Serious answer: on a yearly 130T$ GDP at least a good third is spent on destroying this planet. 50$B which ends up paying phds is barely one peanut.</p>

What does that mean for reality?"]]></title><description><![CDATA[
<p>No string theory (10d) or m theory (11d) map to lower dimensions (eg 4d) via (generalisation of) Kaluza Klein compactification. Vector boson (eg maxwell or Yang mills) are internal degree la of freedom-> 6/7d graviton becomes a photon/ gluon.<p>There’s holography in string theory: AdS/CFT but this rather maps 4d super Yang mills (on the boundary of AdS5) in an AdS5xS5 background: which is one holography correspondence we know works.<p>Holography is much more common, but we only really understand it on hyperbolic spaces.<p>Also since it has a theory at strong coupling on one side we cannot really do calculation on that side and verify it.<p>You can use it tho to make calculations.</p>

<p>I’m out of academia but in defence of former colleagues I note:<p>- Maths and theoretical physics are very cheap (compared to other disciplines)<p>- Maths and physics researchers provide lectures for all other scientific fields<p>- Brut forcing maths/physics problems require debilitating amount of compute/money. This will make research in these topics even more biased towards rich countries.<p>- There most certainly will be pervers effect, ppl refraining from publishing results etc<p>- it’s very unlikely that private ai labs will play ball with academic research. They scrapped the internet and now sell access to their models.<p>As much as I’m happy to see new tools, I have the feeling there will be nefarious effects.</p>

<p>PS2: AdS/CFT (and we have at least one good candidate since Maldacena in string theory) correspondence shows that strongly coupled quantum systems in d dimensions are dual to *classical* gr systems in d+1 dimensions.<p>Somewhere somehow dualities seems to relate completely different systems, that non relativistic dissipative systems happen in all generality somewhere in that mess is barely a surprise.<p>I mean, if one believes ER=EPR GR and quantum mechanics are just the same thing.</p>

<p>Ps: your comment on dissipation is good. But in certain frames GR can reproduce that. I’m far from an expert, but definition of energy is rly hard in GR (need both Noether thms).<p>Research on the topic seems to have stalled a decade ago. Probably for a good reason.</p>

<p>It’s pretty crazy what dynamics you get from NS.. until one realise they emerge from a tiny part of the solution space of Einstein equations.. which themselves emerge at the low energy limit of sth much bigger.</p>
