Products that do what Large Numbers Hypothesis Revisited does
I was reviewing Dirac's Large Numbers Hypothesis (https://en.wikipedia.org/wiki/Dirac_large_numbers_hypothesis) and decided to give it a second go, now with measurements of fundamental constants more precise than 100 years ago. And I stumbled upon a value for Hubble's constant that's uncannily close. Here are the full calculations. https://colab.research.google.com/drive/1K1qoUFvqZp1fWbpcKJWq63nflgwS0ZHh?usp=sharing Meaningless, or meaningful coincidence?

I was playing around with fundamental constants and out popped 13.8 billion light years. What is going on? the wavelength of an electron mass photon / (2pi) * the charge radius of a proton / the black hole radius of a proton = 13.8 billion light years ((h / (m_e * c * 2pi)) * (h / (m_p * c * pi/2)) / (2G * m_p / c^2)) = 13.8 billion light years…

Context: I'm looking at Norman Wildberger's rational trigonometry[1], and here I was wondering how useful it is in physics. So I thought about testing it with the famous simple pendulum exercise. It's not obvious we get any FPS gain, but still I find it cool to even be able to get the same result differently. 1. https://en.wikipedia.org/wiki/Rational_trigonometry

Hi HN! I’ve spent the summer of the past 2 years building The Atlas, a procedural universe simulator that generates 1 sextillion galaxies (10²¹) from a single mathematical seed. Think No Man’s Sky meets theoretical physics, but running entirely in your browser. Everything is purely deterministic, the universe is calculated from SHA-256 hashed seeds using the golden ratio as primordial constant. There’s no database, no pre-saved data, just pure math. Time itself is treated as a coordinate, so the universe exists as a 4D structure where any moment can be computed on demand. Shut it down for…

Hi HN! I built this after seeing several references to Election Truth Alliance on social media, and after reading their analysis, I just couldn't get the problems I saw in it out of my head. So I downloaded the data, and rebuilt their full analysis from scratch. Their critical error is a simple misunderstanding of the Law of Large Numbers: values collected in large samples converge to the true probability in the sample distribution. (not to be confused with the Law of Very Large Numbers: which states that unlikely things happen given enough time. That confused me too) Technical Details: - No…

This is a side project we did. We call it q1tifier (pronounced 'quantifier') and it's main aim is to make sense of numbers. E.g. if you search for the number '5000' one of the result is '5000m = about the length of 89 NASA Space Shuttles' (see it here! http://duuble.com/q1tifier/view/3/=5000) Numbers don't really mean anything by themselves, so through this such numbers could be more meaningful! This idea spawned from seeing infographics that often compare numbers we real life stuff, and we decided to make a database for people to supply such small pieces of info and facts. The database is…

Hey HN! Recently published a book developing new frameworks of meaning and value informed by our most advanced cosmology and physics. It makes the argument for the necessity of spiritual revolution in order to free the abundance trapped in the world, a reimagination that interlinks the spiritual project to systemic reformation. The inspiration for the text draws from my history of social impact work and the frustrations and lessons learned along the way. If it's of interest you can learn more/read it/download it in a variety of formats for free at https://singletruth.org.

Hi HN! I had a math idea whose thread I've been pulling on, and ended up creating this concept of Space Numbers. To read about it, see the pdf at the linked repo: https://github.com/abidsikder/space-numbers I'd appreciate feedback and ideas about the concepts, as well as further mathematical topics to take a look at that might be related, thank you all!!

Input a SMILES string (or pick one molecule from the examples) and it returns up to 100k molecules closest in 3-D shape or electrostatic similarity – from 10+ billion scale databases — typically in under 5-10 s. *Why it might interest HN* * Entire index lives on disk — no GPU at query-time, less than ~10 GB RAM total. * Built from scratch (no FAISS index / Milvus / Pinecone). * Index-build cost: one Nvidia T4 (~ 300USD) for one 5.5B database. * Open to anyone, predict ADMET, export results as CSV/SDF. Full write-up & benchmarks (DUD-E, LIT-PCBA, SVS) in the pre-print:…

I decided I wanted to roll my own AB testing app for Django (https://github.com/crobertsbmw/RobertsAB) when I was finished, I came across this: http://stevehanov.ca/blog/index.php?id=132 Which is a very convincing article on why AB testing sucks and with a few extra lines, you can improve your algorithm to select the best test so you never go back and update your code (yeah right.) I then thought, how many tests does this thing have to run to truly figure out which is best? I made 4 tests with probability of success equalling 1/2, 1/4,…

Hi everyone, I’m a student with a strong interest in computer science and complexity theory. Recently, I worked on a manuscript attempting to prove that P ≠ NP. I know how this sounds — it’s one of the hardest and most debated problems in CS, and many have tried and failed. I don’t claim to have the final answer, but I believe the approach I used might at least offer some fresh perspective or provoke useful critique. The idea involves geometric separation between deterministic and nondeterministic computation, using high-dimensional lattice constructions and some physics-inspired intuition.…

A while back I built a science library supporting both physical and abstract dimensions. Almost immediately I discovered working with floating point numbers suck in that space and BigDecimal isn't much better in terms of managing scale wrt margin of error across calculations, Java doesn't make this easy. Rationals are in my view much better suited for science/math in that information cannot be unintentionally lost when using them. So I made a Rational for Java, and in the process _forced_ Java to work better with science and math.

This is an interactive version of the mass-vs-radius chart from Lineweaver & Patel's "All Objects and Some Questions" (2023). It plots the scale of everything in the observable universe on a single log-log chart This was an experiment in extending the utility of a science infographic via hyperlinks, navigability and tooltips that detail the meaning of specific parts. There are likely still spatial/numerical issues, happy to take corrections. The original paper: https://pubs.aip.org/aapt/ajp/article/91/10/819/2911822/All-...

Hey any astrophysicist reading hn there? Was sick in august (yeah isn't that nice) and made a small python fits table viewer for the terminal with textual. It would be great to have people try it so if you find any issue I can improve it. If you have no FITS file but would like to try regardless there are some test file in `/test`. Ciao!

We’re building TheorIA— an open, high quality dataset of theoretical physics results: equations, derivations, definitions, and explanations — all in structured, machine- and human-readable JSON. Why? Physics is rich with beautiful, formal results — but most of them are trapped in PDFs, LaTeX, or lecture notes. That makes it hard to: - train symbolic/physics-aware ML models, - build derivation-checking tools, - or even just teach physics interactively. THEORIA fills that gap. Each entry includes: A result name (e.g., Lorentz transformations) Clean equations (AsciiMath) Straightforward…

Finding the balance between humans and machines has been the thread through my career. I always had a thing for AI and couldn't wait for it to actually deliver on what was promised. Now it does, and it's more important than ever that humans and machines keep working well together. AI makes creation trivial. Text, code, design, strategy, in seconds. But one thing AI does not create: independently verifiable proof of when something existed. Reproducing is now cheaper and easier than creating. Chronology becomes contestable at the moment it matters most. The universal problem was known. I…

A variant of the Monty Hall problem (the 7th one on this quiz) went semi-viral a couple months ago. For me at least, I may be able to walk through the reasoning of the original problem, and I may be able to convince myself it's correct, but it's very hard to build an intuition for why it's correct that feels truly sound. So I thought it'd be interesting to have a quiz to contort the original problem in as many ways as possible to challenge my understanding and intuition. Try it out!

I am diagnostic radiologist with over 40 years experience. In diagnostic testing, many terms are used to describe how well the test detects the disease or disorder. Examples are “sensitivity”, “specificity”, “predictive values”, “odds ratio”, “likelihood ratios” and numerous others. In the literature and medical presentations there is often not much consistency in their use; as a physician listening to or reading research, I was perpetually unclear on how these terms “fit together”. My solution was to invent the visual 2 by 2 diagram, or truth diagram, as a graphical alternative to the…

Hi HN! Disclaimer: A blog post[0] on this topic ended up on HN's front page recently (which had a link to GlacierMD) but I'd already written this whole "Show HN" spiel so I figured I'd submit it anyway. Hopefully this doesn't come across as too spammy! (The previous post was really more about the problem, not my proposed solution.) Anyway, thanks for checking out GlacierMD—a consumer health tool I've been hacking on for the last few months. I chose long COVID as the first condition because (sadly) lots of people have it[1] and the research is changing rapidly[2]. Unlike other health…
