Geometric patterns in a city.

Walking through a city is like navigating through a sea of geometric patterns!

On all sides: circles, lines, triangles, squares, rectangles!

Look up, look down. See the grates, ironwork, bricks, manhole covers. See the windows and reflections. You’ll find yourself surrounded by architecture designed mathematically.

Some of the patterns are simple. Others are complex.

When you walk through a city, what shapes and patterns do you see?

Most efficient way to eat pumpkin pie.

After performing a very detailed mathematical analysis, noting that the total area of a circle is π r², and after taking precise measurements and observing the object in question with a critical eye, I’ve finally determined the most efficient way to consume pumpkin pie.

Unfolding Humanity appears at Maker Faire!

A couple months ago I blogged about the debut of a fascinating dodecahedron sculpture called Unfolding Humanity. The San Diego Geometry Lab had begun building their project by a parking lot at University of San Diego.

Today I finally saw the interactive metal sculpture completed! It was among the many cool inventions on display at 2018 Maker Faire San Diego in Balboa Park!

If you want to learn more about Unfolding Humanity–the mathematics behind it, and how it’s symmetry and complexity is similar to the structure of the universe–please check out my earlier blog post here, or visit the artwork’s extremely interesting website here.

I learned from Diane Hoffoss, Associate Professor of Mathematics at USD, that the San Diego Geometry Lab might be building additional similar projects in the future. Probably every other year. Because it’s quite an undertaking!

I also learned that many people enjoyed stepping inside Unfolding Humanity during Burning Man! Someone even performed magic tricks inside it!

This is what I saw at Maker Faire San Diego today…

Assembling a beautiful mystery: Unfolding Humanity.

Working to complete Unfolding Humanity. Lit green lettering on the exterior of the sculpture is similar to that from the iconic movie The Matrix.

Late today I swung by the University of San Diego to see something extraordinary.

The San Diego Geometry Lab, with the help of the San Diego Collaborative Arts Project (SDCAP) and the University of San Diego (USD) Applied Mathematics program, is building a complex interactive sculpture called Unfolding Humanity. For a few minutes I admired the metal sculpture which stood outside by a campus parking lot, and watched as USD students and faculty worked to carefully assemble it.

Unfolding Humanity will be on public display this year during Burning Man, and the weekend of Maker Faire San Diego in Balboa Park.

Once completed, people will be able to stand inside the hollow, 12 foot tall dodecahedron. When the mirrored sides fold close, those inside will see their myriad reflections amid thousands of programmable star-like LEDs. They will seem to stand at the center of the universe. The fantastic effect will almost certainly inspire awe and provoke thought. Awe at the beautiful symmetry and complexity of the universe, and thought about its mathematical structure and our place inside it.

This very cool sculpture is fascinating on various levels. The Matrix-like chamber provokes questions about the relationship between technology and humanity. The opening pentagonal walls relate to Albrecht Dürer’s 500-year-old mathematical problem concerning the unfolding of polyhedra. Most interesting to me, the mathematical structure of the universe, based on observations of cosmic radiation, is thought to resemble that of a dodecahedron–the shape of Unfolding Humanity. Standing inside the sculpture might in some way help us sense the mysterious structure of the cosmos itself.

This artwork reminds us all that the universe’s existence, and our existence inside it, is ultimately a profound mystery. As the Unfolding Humanity website states: We human beings do not know who we are, and that is who we are.

Today when I attended Unfolding Humanity’s announced debut, I was under the impression the project was completed. But it turns out construction is ongoing. I learned the interactive sculpture should be finished in perhaps a week or so.

Please visit the San Diego Geometry Lab website. You’ll learn more about the artwork’s conception, historical significance and symbolism. You’ll see cool external and internal renderings of Unfolding Humanity based on a computer model, plus an animation of how it will open and close once completed!

Lobster traps, shadows create a cool matrix.

I got some cool photos yesterday when I walked past new lobster traps on a pier. The cage-like traps and their shadows, which were cast on a clean flat surface, created an illusion of strange dimension and space that captured my eye.

These grids of metal and shadow remind me of some unusual sculptural artwork I recently blogged about in the gallery of San Diego’s Central Library.

The following images almost look like molecules arranged in a matrix. Intersecting parallel lines seem to form an abstract, mathematical, three dimensional space.

San Diego students learn STEM through aviation!

Today I headed to Gillespie Field in El Cajon and checked out an Expo organized by Air Group One of the Commemorative Air Force. As I walked among all sorts of restored World War II aircraft and a wide variety of fascinating exhibits, I made a very cool discovery!

Students in San Diego are invited by Air Group One to participate in a special aviation-themed STEM educational program! The special program is designed for middle and high school aged youth. Ricardo Sevilla, the friendly A-STEM Educational Officer, walked over to introduce himself to me, and I learned a little bit about this truly amazing opportunity.

S.T.E.M subjects (science, technology, engineering, and math) can be taught to students in San Diego classrooms or at Air Group One’s super cool Gillespie Field headquarters, where there are a variety of potential hands-on activities. Topics that are featured include how to become a pilot, how to operate a drone, how to build a rocket, and the aerodynamics and design concepts that enable an airplane to fly. Potential careers in aviation and the aerospace industry are also introduced. Sounds like lots of fun!

Are you a teacher in San Diego who’d like to learn more? Wouldn’t your students be thrilled to visit an actual airfield? Check out this page of the Air Group One website!

Computer Science and a boom box at UCSD!

There are two electrical boxes near the UCSD Gilman Transit Center that caught my eye last weekend. One features tributes to three early pioneers of computer science. The other is painted to appear like a gigantic boom box. Technology and music are central to the life of many students at UC San Diego.

I always love revisiting the campus of UC San Diego. It’s a very beautiful place, bustling with energy. The university is rated one of the finest in the world. When I see the inventors of tomorrow, walking with smiles in the La Jolla sunshine, I feel hopeful.
