Food coloring in milk and detergent

Partway through the experiment, we put a drop of detergent in each dish, breaking up the surface tension of the water and destroying the emulsion of the milk. At this point, the milk actually began mixing much faster than the water, in complex streaks as globules of fat began to coalesce, creating forces that actually mixed the food coloring around. This image is mostly the blue food coloring, but the contrasts showed up much more nicely in black and white.

Blue and yellow food coloring in water

In water, of course, food coloring diffuses much more quickly. I was surprised, however, to see how complex and uneven the diffusion can be. Here we see a drop of blue food coloring apparently following a hidden current in the upper layer of the otherwise still water, "dripping" down to the bottom in swirling pattern of turbulence.

Green food coloring drop in milk

Over the weekend, we did some experiments out of a science book that one of Harriet's friends gave her for her birthday. The one on diffusion produced some beautiful images that I just had to capture. Here you see a drop of green food coloring in milk, diffusing only very slowly and slightly since milk is an emulsion of water and fat.

Flag water tank, Kentucky

Another proud local water-tower, this one themed on the American flag, somewhere in Kentucky.

Metropolis, Home of Superman

Many small towns in the Midwest express their identities through their water-towers. Here we see the pride and joy of the little town of Metropolis, a community in far Southern Illinois of about six thousand people that is officially and legally the home of Superman, according to both DC Comics and the Illinois State Legislature.

Schoolbus storage, near Chicago

I love finding places where you see lots of things from above that normally you only see one or two at a time, like this storage yard filled with dozens of school buses.

High density housing near Chicago

Tight straight townhouses forming a strained approximation of the curves of roads and cul-de-sacs.

Chicago neighborhood

Back to America now, and the complex suburban sigils of our low-density housing patterns.

Intruding medieval tomb, Rimini, Italy

While the modern discoverers of these ancient Roman homes have done their best to preserve them, this was not the case in other eras. Scattered through the site are intrusions from the medieval era, when a cemetery was located atop the site and the deeper burials smashed right through the mosaics to construct their tombs. Ironically, these acts of vandalism are now also ancient historical sites well worth preserving, being well over a thousand years old themselves.

Roman hypocaust, Rimini, Italy

Roman homes were often heated by a hypocaust (literally "under-burn" in Greek): channels beneath a floor into which hot air was forced. The air then heats the floor, which keeps the rest of the house warm as well. Here we see those channels exposed by the breakages of the floor. Hypocausts are a really nice solution that is both efficient and comfortable, and they're occasionally used in modern construction by people rediscovering this architectural innovations---which is how I know that a hypocaust feels really nice on one's feet on a cold winter morning.

Roman mosaic, Rimini, Italy

Some of the mosaics unearthed in the old Roman homes are remarkably well preserved. Their colors have faded, but their contends are clear and sharp.

Roman ruins, Rimini, Italy

A map of the site, showing two Roman homes (one a surgeon's house from the height of the Pax Romana, the other from a wealthy person in the late Empire) and more areas under cover. The site was discovered during the course of ordinary urban renovations, which were then pre-empted by archaeology. I can only think what a mixed blessing it is to build in such ancient lands, where fabulous discoveries and shattered current plans go hand in hand.

Roman ruins, Rimini, Italy

In the middle of Rimini is a wonderful archeological site: the ruins of two old Roman apartment houses, uncovered and preserved in situ in a low half-buried building capping the location where they were discovered beneath a city square. Most of what you see is the floors, but enough low wall bases remain to get a good sense of the shape of these upper-middle-class homes from two thousand years in the past. The size is not unlike that of one of the smaller New York City apartments today.

Roman gate, Rimini, Italy

Closeups on the Arch of Augustus, showing some still-intact portions of its incriptions: part of a "Senatus Populusque Romanus" (The Senate and the People of Rome) and part of the explanation that this is celebrating Augustus' work on the roads. The structures on top, however, are not Roman, but from a later period, when the city actually needed to be defended.

Roman gate, Rimini, Italy

The Arch of Augustus stands at the edge of Roman Rimini, where it once marked the start of a great Roman road spanning from there to the capital.

Closer views of the Ponte di Tiberio, showing its long-weathered surfaces and the abundant mosses and other plants that have lodged themselves in its sides.

Ponte di Tiberio, Rimini, Italy

The Ponte di Tiberio is a bridge dating from the time of the Emperor Tiberius, finished around 20 AD. The Romans being the remarkable engineers that they were, it still carries vehicle traffic today.

Roman amphitheater, Rimini, Italy

All of the rest of the touristy stuff in Rimini is fun to see, but the real treat for me is what I have saved for last: a number of Roman artifacts and ruins, scattered about the city, such as this amphitheater.

Poe by the river, Rimini, Italy

Edgar Allen Poe looks worriedly out from his pose by the corner of a riverbank mural.

And because it's the 4th of July, let me call back to "American Street Food" and "E'Tornato L'Americano."

Avian Love, Rimini, Italy

A peacock and chicken fondly touch beaks in a mural on the riverbank in Rimini. I don't know if there's supposed to be some sort of deeper symbolism there, or if it's just a fun image.

The wall of an old church in Rimini is an oasis of cool grey colors beside the riot of activity surrounding it.

Flowerhead models, Rimini, Italy

Two flower-headed models, lurking together in their inhumanity. I have to admit that I find these mannequins genuinely disturbing to look at, and quite distracting from the clothing that they are intended to be modeling to me.

Flowerhead model, Rimini, Italy

The dehumanization of mannequin models continues apace: she isn't even allowed a face, just a burst of beautiful flowers.

Mickey Mouse Calzature Bimbo, Rimini, Italy

I'm pretty sure that "Mickey Mouse Baby Shoes" is defiantly flouting international copyright law with their odd-looking interpretation of The Mouse, and indeed I really hope they are.

Black bars, Rimini, Italy

I have no idea why this woman is wearing two dark black bars painted on either side of her spine. I can only imagine it will leave a quite unusual pattern in her tan.

Another view of the Rimini beach, looking backwards from the edge of the water to where the condominiums begin to rise.

Packed beach, Rimini, Italy

And this is what everyone apparently comes to Rimini for: beaches that I suppose are nice, but that I would have a hard time enjoying since they are so utterly and completely packed with people. Somewhere down at the end of that apparently endless line of umbrellas is the ocean.

I grew up mostly in Maine, where even on beautiful hot summer days you could just walk down a little farther to find big swaths of open empty beach. To me, that has defined the experience of beaches, and my feeling about a place like the Rimini beach (or other similar that I have seen elsewhere) is one of profound claustrophobia.

Mare That Way, Rimini, Italy

My last stop in Italy last year was an afternoon in Rimini, a seaside city known for intense beaches and Roman ruins. The city is quite clear on why you are more likely to be there though, and everywhere points you clearly to the ocean.

Looking out into the clear air beyond a overlook in the middle of Bertinoro, about halfway down the hill, a few swifts dancing in the air chasing insects.

Reagan Presidente USA,1991, Bertinoro, Italy

Found on a wall of little plaques of names in a restaurant I ate at: I think this means that Ronald Reagan visited Bertinoro a few years after leaving the presidency. I wonder what might have brought him there.

Half-paved wall, Bertinoro, Italy

Cobblestones go halfway up this wall to form a stylishly jagged boundary.
