The Kid Should See This 🌈🪐✨Since the 12th century, Japanese carpenters have created perfect-fitting wooden joints without nails or glue. These techniques have helped wooden structures stand for over a thousand years! 🪵🧩 Watch Dylan Iwakuni demonstrate six beautiful connections including dovetail and gooseneck joints—each showcasing a marriage of <a href="https://universeodon.com/tags/mathematics" class="mention hashtag" rel="nofollow noopener" target="_blank">#mathematics</a>, <a href="https://universeodon.com/tags/engineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#engineering</a>, and patient craftsmanship.👉 For design, engineering, and mathematics enthusiasts: <a href="https://thekidshouldseethis.com/post/the-precise-art-of-japanese-wood-joinery" rel="nofollow noopener" translate="no" target="_blank">https://thekidshouldseethis.com/post/the-precise-art-of-japanese-wood-joinery</a><a href="https://universeodon.com/tags/diy" class="mention hashtag" rel="nofollow noopener" target="_blank">#diy</a> <a href="https://universeodon.com/tags/japan" class="mention hashtag" rel="nofollow noopener" target="_blank">#japan</a> <a href="https://universeodon.com/tags/video" class="mention hashtag" rel="nofollow noopener" target="_blank">#video</a> <a href="https://universeodon.com/tags/tksst" class="mention hashtag" rel="nofollow noopener" target="_blank">#tksst</a>

Project Gutenberg"My methods are really methods of working and thinking; this is why they have crept in everywhere anonymously."Happy Birthday Emmy Noether!!She made many important contributions to abstract algebra. She proved Noether's 1st and 2nd theorems, which are fundamental in mathematical physics. She developed theories of rings, fields, & algebras. In physics, Noether's theorem explains the connection between symmetry & conservation laws.<a href="https://en.wikipedia.org/wiki/Emmy_Noether" rel="nofollow noopener" translate="no" target="_blank">https://en.wikipedia.org/wiki/Emmy_Noether</a><a href="https://mastodon.social/tags/mathematics" class="mention hashtag" rel="nofollow noopener" target="_blank">#mathematics</a> <a href="https://mastodon.social/tags/physics" class="mention hashtag" rel="nofollow noopener" target="_blank">#physics</a> <a href="https://mastodon.social/tags/womeninStem" class="mention hashtag" rel="nofollow noopener" target="_blank">#womeninStem</a>

Dani Laura (they/she/he)I have found a novel family of rep-tiles which produce aperiodic tilings. The prototile is a triangle with smallest side 1 and biggest side 2, the other side is 1 < x <= 2. The family includes one pointed isosceles triangle, the right triangle of angles 30-60-90 (half an equilateral triangle), and other scalene, obtuse or acute, triangles. The first image shows relevant members of the family, the second the substitution rule. The isosceles triangle of the family has another already known aperiodic tiling ( <a href="https://tilings.math.uni-bielefeld.de/substitution/viper/" rel="nofollow noopener" translate="no" target="_blank">https://tilings.math.uni-bielefeld.de/substitution/viper/</a> ) which looks the same but is different because there the tile has no reflections, whereas here some tiles are reflected (in the case of the isosceles triangle the reflection makes a difference when applying the substitution). Figure 3 shows the difference between that tessellation and the one proposed here, mine has just four slopes. Last figure shows a zoom into one big instance of the tiling for the right triangle. <a href="https://mathstodon.xyz/tags/TilingTuesday" class="mention hashtag" rel="nofollow noopener" target="_blank">#TilingTuesday</a> <a href="https://mathstodon.xyz/tags/tiling" class="mention hashtag" rel="nofollow noopener" target="_blank">#tiling</a> <a href="https://mathstodon.xyz/tags/Mathart" class="mention hashtag" rel="nofollow noopener" target="_blank">#Mathart</a> <a href="https://mathstodon.xyz/tags/geometry" class="mention hashtag" rel="nofollow noopener" target="_blank">#geometry</a> <a href="https://mathstodon.xyz/tags/Mathematics" class="mention hashtag" rel="nofollow noopener" target="_blank">#Mathematics</a>
