Andrew Childs created Newton's Orchard, a browser-based space and gravity simulation application, over the summer. [^1]

Newton's Orchard features deterministic time scrubbing, allows all celestial bodies to be edited, and includes different preset systems and experiments. [^2]

The application was inspired by the author's son playing with the 2-dimensional PhET gravity and space simulations during his 5th-grade STEM class. [^3]

The author requested feedback from the Hacker News community specifically regarding how to make the tool engaging and illuminating for students. [^4]

The Hacker News thread 'Ask HN: Who is hiring?' for September 2026 instructs employers to state the job location and include REMOTE for remote work, REMOTE (US) or similar if restricted to a country, and ONSITE when remote work is not possible. [^5]

The September 2026 'Who is hiring?' thread requests that only individuals who are personally part of the hiring company post, disallowing recruiting firms and job boards, and limits posts to one per company. [^6]

The thread directs commenters not to reply to job posts with complaints, as it is considered off-topic, and asks readers to email only if personally interested in a job. [^7]

The thread provides third-party search tools for job seekers, including https://nthesis.ai/public/hn-who-is-hiring, https://dheerajck.github.io/hnwhoishiring/, http://nchelluri.github.io/hnjobs/, and https://hnjobs.emilburzo.com. [^8]
