Hairy circle of spheres | Sketches of Topology
https://sketchesoftopology.wordpress.com/2011/09/07/hairy-circle-of-spheres
Visualizations of low dimensional topology. Hairy circle of spheres. Isn’t too accurate unless there are hairs that are closed circles, but these are the concessions one makes for a dumb play on the Hairy Sphere Theorem. This post doesn’t really have much to do with that theorem. What’s below are some pictures suggesting Seifert fibrations of. The circle of spheres. View this 3-manifold as an interval of concentric spheres where you have to imagine gluing the inner sphere to the outer sphere. In the thre...

Visualizations of low dimensional topology. My how time flies…. Of two topological spaces. Is basically the space of all line segments between every pair of points. As a nice embedded, visceral example of this, a tetrahedron may be viewed as the join of two skew line segments. Indeed this is the illustration on Wikipedia.

Chains and Tangles | Sketches of Topology
https://sketchesoftopology.wordpress.com/2012/02/01/chains-and-tangles
Visualizations of low dimensional topology. These two links have homeomorphic exteriors. They’re both strongly invertible. Let’s quotient the first link by its strong inversion to get a tangle. Then we’ll isotop that tangle around and eventually take its double branched cover to get the second. Notice that this homeomorphism swaps the red and blue meridians and longitudes.

Visualizations of low dimensional topology. Here’s a sequence of images I drew for a talk I gave about a month ago. I reckon there isn’t much more to say that’s not in the images. Hit flickr. Twisting along a disk. Twisting along an annulus. Of course, you’ll probably want the annulus embedded so that its boundary is not a trivial link…. By Ken Baker on November 2, 2012.

A group blog about mathematics. February 16, 2013. Defense Against the Dark Arts: the Reverse Regression Effect. After leaving you indignant and disappointed, a blue activist tells you that according to another study, for every salary level, green men are less educated than blue men, a clear sign of discrimination against the blues — why should blue men study harder in school than green men to get the same rewards for their work? In particular, the paper referenced was Goldberger’s 1984 paper. I’ve...

Sketches of Style
Title: Sketches of Style on an Ocean of Air (Manuscript Art from original "Sketches of Style"). Placed in triangular formats, with oblong shapes as empty space left in the overlapping patterns of placement, emphasizing how style is a condition of emptiness or formlessness or the open-endedness aspect in expression, also known as “Sketches of Style”. It is my inkling that the freedom of empty space is the root of all creative inspiration. Visions of Outer Conflict. An irony to amuse. To walk, or march,.

Szkice z podróży i nie tylko.
Niedziela, 8 stycznia 2017. Wiosna w Toskanii, a dokładnie w Pitigliano. Uwielbiamy włoską jesień, a szczególnie jesień w Toskanii. Pogoda idealna zarówno do zwiedzania jak i plażowania. W zeszłym roku postanowiliśmy jednak pozwiedzać wiosną. Przełom maja i czerwca wydał nam się odpowiednią porą na leniwe wakacje w cudnej Italii. Czy rzeczywiście tak było? Jeśli chcecie się dowiedzieć, zapraszam to czytania i oglądania, bo tym razem jest dużo pięknych fotografii. Linki do tego posta. Za co kocham Włochy.
