A very general and well known example is the fact that the metal we use to build telescopes were once built in stars by nuclear fusion. Hence in a fundamental sense, stars themselves have helped us indirectly in observing them in great detail. In this article I mention a bit more scientifically subtle and an even more interesting example of such a pair which raises interesting thoughts about an old experiment, its beauty and relevance in a very modern tool fo","authors_text":"Aswin Sekhar","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.hist-ph","submitted_at":"2013-05-21T13:59:59Z","title":"Newton's Old Bucket Experiment and the Modern Liquid Telescope"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1305.4821","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:0fc8d9545773c185cd250f92a1f8823dbefe83ec5e73958b721be533c966705a","target":"record","created_at":"2026-05-18T03:25:15Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"f22462df3935843ca962fcedc4d32eb57602b2b04c25639e3dc587632af17618","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.hist-ph","submitted_at":"2013-05-21T13:59:59Z","title_canon_sha256":"067d29bf2b58b11d564361e7a8464bee248e5aef3d1a78830291495594fa6a65"},"schema_version":"1.0","source":{"id":"1305.4821","kind":"arxiv","version":1}},"canonical_sha256":"b6ac1ff30cd59f87a0f66c654db38f4caa02f175014da386334b2ddd52046b6a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b6ac1ff30cd59f87a0f66c654db38f4caa02f175014da386334b2ddd52046b6a","first_computed_at":"2026-05-18T03:25:15.195504Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:25:15.195504Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"dHN6yWWqotUJdj/gENds6zTE6UqgreeiK7+9oJnDJN5yRsIF72SH5B5uizA6Hn1Q1zfJIyTKK31A2v1YhqYYBg==","signature_status":"signed_v1","signed_at":"2026-05-18T03:25:15.195927Z","signed_message":"canonical_sha256_bytes"},"source_id":"1305.4821","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0fc8d9545773c185cd250f92a1f8823dbefe83ec5e73958b721be533c966705a","sha256:3cae2cdfc243b5e624aa7a07af577e575ad3cdeb79622fd96a878ab7e09d7029"],"state_sha256":"a7c2c19b20e3c147639f1ab81944c9f0e07d26d51fffdb6752b0fc38a59260d3"}
