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!

Students, faculty and interested visitors watch work being done on Unfolding Humanity during its debut at University of San Diego.

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.

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!

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.

Two different buildings are reflected in the glass windows of 101 W. Broadway. On the left is the Spreckels Theater Building; on the right is the Sofia Hotel.

I confess that I love reflections. They often seem magical, like a glowing vision of intermingled dimensions. So I had to take more photos today of windows reflected in glass windows.

Walking down Broadway in downtown San Diego is like moving through a funhouse maze. Left and right, the mirrors rise into the sky. One passes through an otherworldly geometry of reflected forms; light dances like the spinning sun upon bright buildings.

Many old redundant photos are being purged from my computer this weekend. But I had to definitely share these!

I’ve blogged about San Diego’s relatively new downtown library several times. I’ve posted more than a few pics of its unique lattice dome. You might recall some weirdly halo-like photos I took in the darkness early one night last year.

Well, check these out! The curving lines of steel reflected in the building’s windows look like a lesson in complex geometry. You know, in a strange way the dome reminds me of a graph or diagram demonstrating how time and space can be warped by gravity! Am I crazy? What does it look like to you?

HOW TO MAKE MATCHBOX ROCKETS THAT REALLY WORK!

Here’s how you can make a tiny rocket that actually works in much the same way as a real solid-fuel rocket. Wrap a single matchstick in a small strip of tin foil, then crimp one end. Look at my photos to get an idea of what to do. Be careful! You know what they say about playing with matches! Have an adult help out!

Oh, I forgot to mention. This cool experiment is courtesy of the Magnolia Science Academy!

HOW TO MAKE AN “AIRZOOKA” THAT SHOOTS CO2 RINGS!

Here’s another cool project I discovered at the Magnolia Science Academy booth. A student had created a simple “Airzooka” that shoots perfect white cloudy rings of carbon dioxide!

The trashcan with a hole part looks easy. To create the membrane that launches the CO2 rings, you’ll need to use a somewhat flexible material, like a plastic sheet. Once the can is filled with gas, just slap it with your hand and out comes a “smoke ring”!

HOW TO CRAFT A FUN PAPER BAG HAT

What can you do with a paper grocery bag? Crumple it up a bit and form a Mad Hatter hat! Use your imagination and maybe a bit of glue!

This crafty idea is provided by the San Diego County Fair. This summer’s fair will have an Alice in Wonderland theme! I can’t wait!

HOW TO MAKE A TINY PARACHUTE

I remember creating one of these when I was a kid. I made my parachute for a toy action figure! Just look at the picture and go to work! Pretty simple!

This parachute was put together by to the Reuben H. Fleet Science Center. The Fleet, located in Balboa Park, is a super cool place with loads and loads of fun hands-on science exhibits for kids, plus an awesome IMAX theater and planetarium!

HOW TO MAKE A SUPER COOL STAR WARS COSTUME!

Okay. No instructions here. Just imagination. That cool costume is actually made of all sorts of Star Wars toys! Incredible. I’m guessing that wicked-looking dude is on the Dark Side.

I believe this guy was part of the STAR WARS Steampunk Recycled Fashion and Engineering Challenge.

Yeah, making a cool costume out of Star Wars toys might take a bit of glue. But all you really need is determination and imagination! (And maybe a credit card.)

HOW TO MIX UP SOME SNAIL GOOP

Slime…snail goop…boogers…it’s all the same good stuff. At least it’s the same mixture of borax powder, water and white glue. A truly yucky and wonderful substance. Science rocks!

Thanks (maybe) to the Steam Maker Workshop for this gloppy sight.

Okay, snail goop is pretty much the same stuff as slime. But I like the name!

HOW TO CREATE A 3-D OPTICAL ILLUSION WITH STRING

Here’s a cool experiment that demonstrates concepts in math and spatial geometry. Perhaps imagine that the string is a ray of light. From the “tower”, stretch the string so that it touches each of the four top corners of your cube, and plot where the string finally reaches your piece of paper. Connect those points with lines the way my photographs show, then look at the image from the end of the string! It looks like some sort of weird optical illusion, but you’ll see the result actually makes sense!

This exhibit was provided by San Diego State University’s InforMath Collaborative.

By using a string attached to this tower, you can plot the projected corners of a cube or other three dimensional object onto a flat two dimensional surface.

HOW TO ASSEMBLE A COOL TENSEGRITY CONSTRUCT

Oh, man! I think you could construct most of this cool stuff with Tinkertoys. Look at the diagrams and go wild! You’ll need lots of rubber bands!

Tensegrity is another science concept that was being demonstrated at the STEM education event. A friendly gentleman explained that the sticks are like bones and the rubber bands are like muscles. So human beings and other critters are examples of tensegrity!

Oops. I apologize for not knowing who put on this exhibit.

What the heck is tensegrity? A funny word created by Buckminster Fuller. You can use rubber bands to add tension to popsicle sticks and create cool stuff.
