Ask HN: Expository/Succinct Books on Modern Physicshttps://news.ycombinator.com/item?id=46473352What are some good books which give an overview of all of Modern Physics (or even better, all of Physics)? Mathematical rigour is fine as long as they are clear and starting from undergrad level. Books for each of the quadrants mentioned here - https://en.wikipedia.org/wiki/Modern_physicsI have my eye on John Dirk Walecka's (https://en.wikipedia.org/wiki/John_Dirk_Walecka) books which seem pretty good particularly the ones published by World Scientific Publishing. Three vols on Introduction, Advanced, Topics on Modern Physics and Introduction vols on Classical Mechanics, Quantum Mechanics, Statistical Mechanics, Electricity & Magnetism, General Relativity. - https://www.worldscientific.com/author/Walecka%2C+John+Dirk?...Dover has Robert Sproull's Modern Physics which seems a bit old. - https://store.doverpublications.com/products/9780486783260Springer has S.H.Patil's Elements of Modern Physics which seems up to date. - https://link.springer.com/book/10.1007/978-3-030-70143-7Does anybodJan 3, 2026 6:35 AM

Show HN: Open-source AI workflows with read-only auth scopeshttps://github.com/seer-engg/seerHey HN! I'm Akshay, and I'm launching Seer - yet another AI workflow builder with granular OAuth scopes.GitHub: https://github.com/seer-engg/seer Demo video: https://youtu.be/cmQvmla8sl0The Problem: We've been building AI workflows for the past year and kept running into the same issue: existing platforms (n8n, Langflow, Flowise) require full access to your Google services even for read-only operations. Want to summarize emails? You're also granting send permissions. Want to read docs? You're also granting edit permissions. If you want granular scopes, the onus is on you to:- Create your own OAuth app with Google (1-2 weeks approval time) - Modify source code to support read-only scopesWe saw this pattern repeated across Discord channels and GitHub issues - developers asking for better scope support, maintainers saying "you can configure it yourself."Our Solution: Seer ships with read-only auth scopes as the default for common operations. It's self-hostable, so your data never leaves yJan 2, 2026 10:16 PM

Show HN: A holiday side project to make Anki flashcards without breaking flowhttps://github.com/mortsnort/MasterFlasherHi HN,Do you consume tons of information but wish you retained more of it? Me too. Over the holidays I vibe-coded MasterFlasher, an Android app that turns content into AnkiDroid flashcards without interrupting what you’re doing.The core insight: the moment you think “I should remember this” is rarely the moment you want to stop and make flashcards. MasterFlasher lets you silently share content from any app to an inbox, then batch-process it into cards later.How it works:Share from any app → content saves silently to a local inbox (no UI interruption)URLs: in-app browser extracts article text via Readability.jsPDFs: text extracted on demand via pdf.jsFlashcard generation uses a multi-step Gemini pipeline: fact extraction → scoring → card generationReview/edit cards, then push directly to AnkiDroidDesign choices:Capacitor + Ionic + React, with Java plugins for the in-app browser and Room storageBYOK: you provide your own Gemini API key (no server or proxy)API keys stored on-device using Jan 1, 2026 11:58 PM

Show HN: I built a weather alert system for photographershttps://app.photoweather.app/demo/live-demoI kept missing the good stuff (fog, aurora, beautiful sunsets) because I wasn't checking forecasts at the right time, so I built PhotoWeather...You define rules like: `aurora_quality > 60 AND cloud_cover < 20% AND moon_below_horizon` `fog_prob > 70% AND within 30min of sunrise AND wind < 5 mph`When a rule matches, you get an email and/or an iCal event. The iCal feed is the part I am maybe most proud of: subscribe once and upcoming "shoot windows" show up in your calendar.One example that made me sure this wasn't just a toy: last October it alerted "clear skies + no moon + strong aurora" and I drove to a nearby high spot in Helsinki. Ended up catching aurora and Comet C/2025 A6 (Lemmon) in one frame: https://reddit.com/r/Finland/comments/1obc5nz/Not my best photo ever, but probably the most unique and memorable, and I'll continue to remember my real-life "photoweather actually works" moment through it.A few things that differentiates this from your average weather app:Spatial sampling AJan 1, 2026 12:54 PM

Show HN: A Multi-agent system where LLMs challenge each other's answershttps://news.ycombinator.com/item?id=46435835Hey HN,I've been experimenting with forcing multiple LLMs to critique each other before producing a final answer.In practice, I kept working around single-model limitations by opening multiple tabs, pasting the same question into different models, comparing responses, and then manually challenging each model with the others' arguments. (Maybe some of you can relate.) It worked sometimes, but it was cumbersome, slow, and hard to do systematically and efficiently.Based on my own experiments, a few things seem to drive why different models arrive at different responses: they have different guardrails, different tendencies encoded in their weights, and different training data. And the biggest kicker of all: they still hallucinate. The question I wanted to test was whether making those differences explicit, rather than relying on one model to self-correct could reduce blind spots and improve the overall quality of the answer.So I built Consilium9.The problem: When a single LLM answers a conDec 30, 2025 5:41 PM

Phantom Blade Zero dated for 2026: bold revolution or the next big overpromise?https://news.ycombinator.com/item?id=46433989With an official launch date set for September 9, 2026, Phantom Blade Zero has moved from mysterious showcase darling to a concrete entry on the industry calendar. Developed by S-GAME and built on Unreal Engine 5, the title blends wuxia storytelling, Hong Kong martial arts cinema energy, and a self-defined “KungfuPunk” aesthetic while positioning its combat as fast, elegant, and distinct from the Soulslike mold it was initially compared to. The story centers on a protagonist with only 66 days to live after being framed for a murder, layering urgency with political intrigue and moral tension.Beyond the narrative, there is serious industry weight behind this date. The game has already surpassed a million wishlists across platforms and is slated to land first on PS5 with timed exclusivity, before expanding to PC. This marks another major swing by a Chinese studio aiming to compete directly with the dominant Japanese and Western AAA space — not just with production spectacle, but with cultDec 30, 2025 3:05 PM

Show HN: Beauty Arena – An Elo-based experiment to measure aestheticshttps://beautyarena.vercel.appHi HN,I built Beauty Arena to solve a data problem I've always found annoying: absolute rating scales (1-10) are terrible for subjective data. They suffer from massive inflation and inconsistent user baselines (one person's 7 is another person's 5).I wanted to test if pairwise comparison (1v1) could produce a cleaner, strictly relative dataset.Instead of asking "How beautiful is this person?", the system asks a simple question: "Who do you choose?". It uses a ranking system inspired by competitive games (Elo/Glicko) under the hood. As users vote, a global ranking emerges based on win/loss ratios against others rather than accumulated points.I'm curious about the "wisdom of the crowd" limits here. Does a pairwise sort actually converge on a clear consensus, or does it cycle indefinitely due to intransitive preferences (A > B, B > C, but C > A)?I'd love feedback on the ranking methodology and the overall UI.Dec 30, 2025 12:56 AM
