smath··on Spherical CNNs (2018)
also relevant to 3d modeling of molecules using in drug discovering modeling -- and a subset of these authors have published along those lines more recently -- for e.g. https://arxiv.org/abs/2104.13478
smath··on AGI is not multimodal
Yes there are protein language models (e.g. [1]), and since DNA encodes proteins, they are effectively DNA language models. Its a hot area of work feeding drug design.

smath··on I should have loved biology too
Ha, same here! Bought that book about a year ago after reading that post
smath··on Why drinking coffee in Iran has become so complicated
I think both extremes can be suboptimal (no choice and too much choice). See for example ‘the paradox of choice’ - research done by Barry Schwartz and later by Sheena iyengar https://modelthinkers.com/mental-model/paradox-of-choice
smath··on Don't force your kids to do math
About a year ago I came across the concept of ‘math circles’, here on HN. It was this longish but very interesting article: https://www.thepsmiths.com/p/review-math-from-three-to-seven...

The key element here is nurturing curiosity. Since then i and my 10yr old have been sitting through a virtual math circle led by Aylean McDonald on parallel.org.uk an organization run by Simon Singh

smath··on American Disruption
Q is anyone knows: would yield on the 10y going down actually help the US to refinance its existing debt (akin to a mortgage refinance), or simply issue new debt more cheaply?
smath··on Understanding Machine Learning: From Theory to Algorithms
+1 for Simon prince’s UDL book. Very clearly written
smath··on James Webb Space Telescope reveals that most galaxies rotate clockwise
Several folks here have recognized that the spin direction depends on whether you look at the plane of the galaxy from ‘above’ or ‘below’. One thing I didn’t see in the article is how the two types of galaxies are distributed across the 3D spherical coordinates when viewed from the earth (or rather from the JWST).

Im thinking: what if there are a bunch of massive objects like black holes in certain directions that are causing the light to bend in a certain way. So what would normally be light coming from the top of the galaxy plane, is actually light reaching us from the bottom of that plane. Would this slew the distribution of the spin one way - I don’t know.

smath··on I genuinely don't understand why some people are still bullish about LLMs
To me, the bullishness stems from the observation that current gen of LLM an plausibly lead to a route to human level intelligence / agi, because they have this causal behavior: (memory/context + inputs) --> outputs. Vaguely similar to humans.
smath··on Tracing the thoughts of a large language model
Reminds me of the term 'system identification' from old school control systems theory, which meant poking around a system and measuring how it behaves, - like sending an input impulse and measuring its response, does it have memory, etc.

smath··on Larry Ellison wants to put all America's data in AI, including DNA
Doesn't need to be a binary choice (above/below threshold) - it can be a spectrum -- also known as progressive taxation.

Would this prevent people from working hard and being enterpreneurial? Not sure but I think not -- for 2 reasons: (i) success at that level requires more than just desire for money, because it requires pushing hard when the going is tough, and unless you care about it you will give up. we have heard this before from others (Steve Jobs?) (ii) a successfull entrepreneur will still make more money than an employee, so the financial incentive is still there, even with greater taxation.

smath··on America desperately needs more air traffic controllers
Ah interesting - a formula. To me it seems that makes it not a free market. Ie the formula is producing numbers that are too low, than what the current demand supply imbalance would otherwise produce.
smath··on America desperately needs more air traffic controllers
I might have missed this in the article - how is the pay level set for ATC staff? In a free market economy price is the magical signal that is supposed to increase supply when there is unmet demand.
smath··on Math and puzzle fans find magic in Martin Gardner's legacy
Yes that’s the one. I’d suggest sit through on of their parallel circles with your son- it’s a free 45 min casual live only session, on Sundays. And the schedule is by age group - listed on their website
smath··on Math and puzzle fans find magic in Martin Gardner's legacy
Gardeners books and sci-am columns are an amazing resource to get kids and teens interested in math.

In the present time, I find Simon Singh’s parallel.co.uk has been doing interesting work holding weekly math circles for kids - deftly engaging kids with mathematical ideas. I attend a circle with my 9 yo every Sunday.

smath··on Ask HN: What's the most creative 'useless' program you've ever written?
About 12 years back I wrote a script to draw what I called “prime factorization trees”. I had recently discovered graphviz and it seemed interesting to combine prime factors with graphviz:

https://thebayesianobserver.wordpress.com/2012/10/07/factor-...

It served no purpose at the time.

I recently printed these pictures out to show my kid who has just learnt about primes / prime factors. The gleam in her eyes was priceless :-)

smath··on The Golden Road: How Ancient India Transformed the World
Good summary, even if I disagree with the 3rd piece being called a golden age. But my question is why ignore the cholas, pallavas and pandyas? Only because they didn’t capture the whole subcontinent? Our schools history books were Delhi centric but we don’t have to be going forward. Those 3 empires had a lot of arts and culture too - and in terms of impact, they spread to parts of SE Asia too.
smath··on The Golden Road: How Ancient India Transformed the World
The Mauryans and Mughals settled and did not rule with the goal of extracting / plundering. The British EIC did the latter. Arts and culture can prosper sustainably only when basic needs are well met, otherwise it is only the privileged that can dream of arts.
smath··on The Rate of Return on Everything, 1870–2015 (2019)
Doesn’t this contradict Robert Shiller who shows that housing returns are flat in the long term?
smath··on 'Not of faculty quality': How Penn mistreated Katalin Karikó
This was my immediate thought too. We need perhaps a long lived website that captures misjudgement on the part of people in power and update their scores over a long period of time. A kind of public record, ledger. A kind of wikipedia, but simplified only to record +1s, -1s against their name, and the reason for it.
smath··on 'Dumbphones' make a comeback: 'No one calls me anymore'
I've thought about making the switch for a longg time. What I worry about is:

* Will they work on all cell towers, i.e. are all towers backward compatible? Can anyone confirm? * Losing out on whatsapp and google maps.

smath··on The largest DDoS attack to date, peaking above 398M rps
That would be giving away some of the secret sauce on the part of the cloud providers. They are selling security as (part of their) service. There are some community shared lists of botnets ofcourse, but they may not be vry real time or very up to date.
smath··on Weird A.I. Yankovic: a cursed deep dive into the world of voice cloning

smath··on Ray-Ban Meta Smart Glasses
I was thinking of an audio-based personal assistant running on the sunglasses, a la https://twitter.com/ggerganov/status/1640416314773700608
smath··on Ray-Ban Meta Smart Glasses
Any word on whether they will let custom code/apps run on this, or is it a walled garden? Whisper + LLM with these would be nice. These glasses could also be great for vision impaired folks.
smath··on Unlimited Kagi searches for $10 per month
I don’t see an option to “try before I buy” (without setting up an account) but maybe it’s there? That’d be useful to win over users. Account set up is friction
smath··on Apocalypse Proof: 33 Thomas Street in New York City
Hey Carlos, I remember you (nanocubes!!). I was in the security research group.

Re stories: — the building has a well!! — apparently it is well stocked with enough food for a month for 20-30 ppl. I never independently verified this. — lots of tourists would walk up to the front entrance and try to poke around — yes no windows. My group tried to install screens in the office with feeds from cameras pointing outside - we were told it had 6 ft thick walls to withstand nuclear radiation

smath··on Apocalypse Proof: 33 Thomas Street in New York City
Ha, I used to work inside this building in 2010.
smath··on Shrinkflation Tracker
% change is over what time frame? YoY?
smath··on Winner’s Curse: Negotiation Mistakes to Avoid
I think what this article misses is that 'value' is a personal/subjective thing. Value is not the same as price. To me, the value of a house might be higher than to you (say because I am more desperate to move out of a tiny apartment). This does not hold for the jar of coins example in the article of course.
