Niles Johnson<p>I just saw the news that FreeCAD 1.0 has been released! They've resolved the most annoying problem, and I think it's an interesting one even if you're not into 3d printing: Certain design operations that change the topology of a 3d model would completely break it :(</p><p>This was called the "topo naming problem", because the root cause was (as far as I can tell) an ill-advised internal naming convention for vertices, edges, and faces. Since the naming convention was such a fundamental part of the software, fixing it took a *lot* of hard work. And, like every open source project, it also required resolving human problems between people who had different ideas for how to solve it.</p><p>Their 1.0 announcement post is sweet, and includes a nod to some of those difficulties, without airing all the dirty laundry. Worth a read, IMO.</p><p><a href="https://blog.freecad.org/2024/11/19/freecad-version-1-0-released/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">blog.freecad.org/2024/11/19/fr</span><span class="invisible">eecad-version-1-0-released/</span></a></p><p>And, if you *are* into 3d printing but left FreeCAD because it was just too aggravating, maybe consider checking out this new version! </p><p><a href="https://mathstodon.xyz/tags/FreeCAD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>FreeCAD</span></a> <a href="https://mathstodon.xyz/tags/topology" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>topology</span></a> <a href="https://mathstodon.xyz/tags/3dprinting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>3dprinting</span></a></p>

QUINTO project<p>Interactions and order</p><p>Interactions can do many things, but one of the most important effects is causing the system to order. A simple example is a magnet. As I mentioned in the previous post, electrons have a quantum property called “spin”. In a crude, cartoon picture, it means that they can rotate around an axis (say, the “z” axis) clockwise or anticlockwise, which is represented by up and down arrow.<br><a href="https://fediscience.org/tags/physics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>physics</span></a> <a href="https://fediscience.org/tags/CondensedMatter" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CondensedMatter</span></a> <a href="https://fediscience.org/tags/CondMat" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CondMat</span></a> <a href="https://fediscience.org/tags/science" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>science</span></a> <a href="https://fediscience.org/tags/topology" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>topology</span></a> <a href="https://fediscience.org/tags/quantum" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>quantum</span></a> <a href="https://fediscience.org/tags/QuantumComputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>QuantumComputing</span></a><br>[1/6]</p>
Charlotte Aten<p>I posted a new paper on the arXiv!</p><p><a href="https://arxiv.org/abs/2409.12923" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">arxiv.org/abs/2409.12923</span><span class="invisible"></span></a></p><p>In "Higher-dimensional book-spaces" I show that for each \(n\) there exists an \(n\)-dimensional compact simplicial complex which is a topological modular lattice but cannot be endowed with the structure of topological distributive lattice. This extends a result of Walter Taylor, who did the \(2\)-dimensional case.</p><p>I think this kind of result is interesting because we can see that whether spaces continuously model certain equations is a true topological invariant. All of the spaces that I discuss here are contractible, but only some can have a distributive lattice structure.</p><p>A similar phenomenon happens with H-spaces. The \(7\)-sphere is an H-space, and it is even a topological Moufang loop, but it cannot be made into a topological group, even though our homotopical tools tell us that it "looks like a topological group".</p><p>This is (a cleaned up version of) something I did during my second year of graduate school. It only took me about six years to post it.</p><p><a href="https://mathstodon.xyz/tags/math" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>math</span></a> <a href="https://mathstodon.xyz/tags/topology" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>topology</span></a> <a href="https://mathstodon.xyz/tags/algebra" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>algebra</span></a> <a href="https://mathstodon.xyz/tags/AbstractAlgebra" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AbstractAlgebra</span></a> <a href="https://mathstodon.xyz/tags/UniversalAlgebra" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>UniversalAlgebra</span></a> <a href="https://mathstodon.xyz/tags/combinatorics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>combinatorics</span></a> <a href="https://mathstodon.xyz/tags/LatticeTheory" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LatticeTheory</span></a></p>
