My latest for @forbes is about a fascinating study from the University of Toronto. I'd really appreciate it if you'd consider reading it (as it took a tonne of work, and I think it's interesting!)

Here's the University Building in its full context. (See my previous post for details.)

The University Building (built 1911) in downtown Denver is one of my favorites due to its beautifully ornate and thoughtfully composed crown.

The top 1.5 floors read as an elaborate three-part composition:

At the top of the building's main brown-brick volume is a highly articulated, multi-layered, light-colored stone course or frieze comprised of various panels and carvings that serves as a strong, horizontal base to the composition. Rising from this base is the middle (and, to me, the most compelling) part: green, glazed terra-cotta "pinstriped" ribs that align with a modillioned cornice, giving each vertical band the appearance of its own miniature crown, that curve outward to form a continuous fluted band that encompasses the top-floor windows and provides vertical thrust and visual support to the third part: the thick projecting cornice with classical ornamentation that caps the building as a parapet, serves as the horizontal mate to the base, and completes the building's crown with authority.

This tripartite "horizontal – vertical – horizontal" composition of the building's crown mirrors the classical order of "base – shaft – capital" with the crown itself serving as the "capital" to the entire building, creating a nested hierarchy of classical-order compositions. Bathed in the bright Colorado sun, this building's exuberant crown makes me feel joyful every time I look at it.

Good idea: Monocabs

monocab-owl.de/english-languag

MONOCABs are gyro-stabilized vehicles that balance on just one rail of a standard train track. They are so compact and narrow that they can pass by each other in opposite directions. Each cabin can accommodate four to six passengers.

Flexible rail-based mobility concepts with "service-on-demand" on reactivated lines could provide a connection to transport hubs in medium-sized centers and thus form the backbone of a multimodal mobility concept in rural areas in the future.
The main advantage is the higher flexibility compared to classic timetable-based rail transport to create an attractive offer for users within the framework of a digital mobility booking and guidance system.

A look back... to my visit to Nördlingen, Germany.

The covered walkway atop the medieval wall that surrounds the town center. Spaced along the outer stone wall are small openings for soldiers to shoot at the attacking enemy.

You can walk along the top of the medieval wall and circumnavigate the entire town center. Here's a view of the Löpsingen tower gate from atop the wall.
