- Paleontology (Wikipedia)
Paleontology (/ˌpeɪliɒnˈtɒlədʒi, ˌpæli-, -ən-/), also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and developed rapidly in the 19th century. The term has been used since 1822 formed from Greek παλαιός (‘palaios’, “old, ancient”), ὄν (‘on’, (gen. ‘ontos’), “being, creature”), and λόγος (’logos’, “speech, thought, study”).
- Hexagonal Grids from Red Blob Games (redblobgames.com)
This guide will cover various ways to make hexagonal grids, the relationships between different approaches, and common formulas and algorithms. I’ve been collecting hex grid resources for over 25 years. I wrote this guide to the most elegant approaches that lead to the simplest code, starting from the guides by Charles Fu and Clark Verbrugge. Most parts of this page are interactive.

- Torx (Wikipedia)
Torx (pronounced /tɔːrks/) is a trademark for a type of screw drive characterized by a 6-point star-shaped pattern, developed in 1967 by Camcar Textron. A popular generic name for the drive is star, as in star screwdriver or star bits. The official generic name, standardized by the International Organization for Standardization as ISO 10664, is hexalobular internal. This is sometimes abbreviated in databases and catalogs as 6lobe (starting with the numeral 6, not the capital letter G). Torx Plus, Torx Paralobe and Torx ttap are improved head profiles.
- Hexagon (Wikipedia)
In geometry, a hexagon (from Greek ἕξ, hex, meaning “six”, and γωνία, gonía, meaning “corner, angle”) is a six-sided polygon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.
