Hyperboloid Shaped Roof
James S. McDonnell Planetarium
Forest Park
Saint Louis, Missouri, USA

This unique roof is made of a concrete shell no thicker than 3.5"

The curved form of a white concrete roof in a hyperboloid shape set against a blue sky with thin wispy white clouds.

Test new black paper and new colored pencils ... by constructing a hyperboloid ... by letting a line segment rotate about an axis!

Also: Adding proper annotations of points and lines for the first time.

#MathArt #SciArt
Descriptive geometry construction of a hyperboloid, by rotating a line segment skew to the axis of rotation. Colored pencils (mostly white) on black paper, extensive annotations of points and lines. By elkement 2026.

I 3D-printed this pencil holder, which resembles the ruled surface version of a hyperboloid of one sheet. I didn't design it. I downloaded it from Thingiverse: www.thingiverse.com/thing:1401060

Everybody always says "light cone" but I prefer "light degenerate hyperboloid."

I've drawn another hyperboloid, now the two-part version: The Mass Shell of physics, relativistic energy as a function of momentum (two dimensions).

#physics #mathsky #mathart #sciart

Colored pencils on black paper, traditional descriptive geometry.
Orthographic projection of a two-part hyperboloid, symbolizing the mass shell in physics. Colored pencils on black paper, mostly white. Traditional descriptive geometry with annotations. Level lines (circles shown as ellipses in the projection) partly highlighted in green and blue, asymptotic cone with orange accents.

My first 3D print! Started with a hyperboloid pencil holder for some vintage Canadian pencils. #circles #MathPhoto25 @edtechcocek.bsky.social en.m.wikipedia.org/wiki/Hyperbo...
12 pencils arranged on a circular base to form a hyperboloid. 3D printing in progress.

MoMath will host a free online event on Friday, Aug 28 at 12:00pm US Eastern time premiering a new video by Sabetta Matsumoto, Tim Reinhardt, Jürgen Richter-Gebert, and me, on hyperboloids made out of sticks and how they move. Details and registration at momath.org/hyperboloids/
A hyperboloid of one sheet made out of wooden skewers next to Mae West, an enormous sculpture of a hyperboloid of one sheet in Munich. Next to the wooden skewers hyperboloid is written “This one doesn’t exist”.

"not sucking ass is in fact a small neighborhood of the focus of the very high dimensional hyperboloid manifold of meaning that intersects with the space of ideas, and that's true taking both is- and ought-eigenbases" would be the absolute most based way for analytical philosophy to end.

I have drawn something from my past - as an experimental physicist working with lasers:

The hyperboloid-shaped envelope of a Gaussian Beam!

Physics art notebooks - from original geometrical drawings on black paper.

Different drawings on front and back side, e.g.

1) Theory of the gyroscope, Poinsot's cones annotated wih their German names
2) Special relativity, hyperboloid-shaped energy-momentum relation

#SciArt #MathSky
Photo of a spiral bound notebook, front and back printed with different geometrical constructions - colored pencils on black paper, white margin reminiscent of a mat. The constructions shows the 1) cones used in Poinsot's theory of the gyroscope and 2) the hyperboloid representing the mass shell in special relativity.

Me: just playing with parametric curves.
Also me: accidentally rendered what looks like a hyperboloid of 1 sheet inside a truncated ellipsoid. In 2D. #mathart #oopsits3D

The Shukhov Towers on the Oka River in Russia, the world’s only diagrid hyperboloid transmission towers.

Pictured in 1988, only one stands today because the entire left tower was stolen, Carmen Sandiego style, in 2005.

Hello, new followers! Sometimes I make neat figures: (explanation in alt text)
A figure of two different types of hyperboloids and a cone, nested in a "natural" way as defined by the geometry of Minkowski space. The surfaces are level sets of the invariant Lorentz interval being constant. When x_\mu x^\mu is negative we get a hyperboloid of two sheets (only the top one is shown, green). When x_\mu x^\mu = 0, we get the light cone of the origin (orange). When x_\mu x^\mu is positive, we get a hyperboloid of one sheet (blue). The text below the figure reads: Figure 2.3: Level sets of the invariant Lorentz interval being timelike (green, top), lightlike (orange), or spacelike (blue, outermost). A quadrant has been cut out for visibility. If the ambient space is (d + 1)-dimensional Minkowski, the geometries on the submanifolds are H^d (green, top), a “null” geometry (orange), and d-dimensional de Sitter spacetime (blue, outermost).
