A growing skyscraper sheds its skin:
Because skyscrapers are lined with hard cement or brick rather than flexible mammalian skin, they need to shed their skin as they grow. The outer layer of any given skyscraper will slough off five to fifteen times over the course of the skyscrapers lifetime. In glass skyscrapers, the skin shatters and rains down on passersby, which is why you see them covered in special tarps during their construction.
Most skyscrapers over 40 stories will shed only during their development, ceasing to grow new skin once mature. Smaller buildings between 10 and 40 stories may continue to shed into adulthood, changing color or texture to match the whim of their owner.
The tower seen above is 44 stories and under development. Before it’s mature, this tower will also grow windows and if male, a lightning rod. A complete skyscraper of the same design can be seen in the background, it has shed for the last time and has its windows intact, making it at least 2 years old. It lacks a lightning rod and is thus a female skyscraper. This is the only known difference between skysexes.
Finally, note the ominous cloud. It’s not really important but boy is it ominous.

PHYSICISTS and MATHEMATICIANS of the ANCIENT WORLD
Images and descriptions (with revision here) reprinted from: Perimeter Institute
Anaximander / Ἀναξίμανδρος(c. 610-546 BCE) is widely regarded as the world’s first physicist – the first to record his belief that nature followed fixed laws. He conducted the earliest recorded experiment, and introduced the sundial and other instruments.
Pythagoras of Samos / Πυθαγόρας ὁ Σάμιος (c. 570-495 BCE) discovered the Pythagorean Theorem: that a square laid along the long side of a triangle covers the same area as the two squares laid along the two shorter sides.
Euclid / Εὐκλείδης (c. 325-265 BCE) built up a complete description of space from a handful of axioms, such as “two parallel lines never cross.” He’s remembered as the “father of geometry,” and the particular kind of space he described, where parallel lines never cross, is now called “Euclidian space.”
Archimedes / Ἀρχιμήδης (c. 287-212 BCE) was an early scientist and engineer, maybe one of the most brilliant mathematicians of all time. He designed a number of innovative machines and discovered the principle of displacement: that the weight of an object floating in water is equal to the weight of the water it shoves aside.
Hypatia / Ὑπατία (c. 360-415 CE) was the headmaster of the Platonist school at Alexandria, where she taught mathematics and astronomy. She invented the astrolabe and perhaps the hydrometer, and wrote several major books on geometry.
Āryabhaṭa / आर्यभट (476-550) was a pioneer of mathematics and astronomy in India. He is believed to have devised the concept of zero and worked on the approximation of pi.
Abū ʿAlī al-Ḥasan ibn al-Ḥasan ibn al-Haytham / أبو علي، الحسن بن الحسن بن الهيثم [Latinized as Alhazen or Alhacen] (965-1040) was a mathematician, astronomer, and philosopher, sometimes known in Europe as simply “the physicist.” He invented the camera obscura and is the father of modern optics.
Wikipedia adds: “He has been described as the father of modern optics, experimental physics and scientific methodology and could also claim to be the first theoretical physicist.”

montreal street artist roadsworth tries not only to beautify the urban landscape, often by incorporating existing street markings, but to also make a statement about the illusory urban disconnect from the natural environment. his (literal) street art is both a reclamation of a public space that as cyclists and pedestrians we are taught is dangerous, and a response to the primacy afforded to a car culture that largely dictates the planning of this public space. for his efforts, roadsworth was charged with 53 counts of mischief in 2004.
