Pacific Paradise, Pt. 5

Molokai, Hawai'i, has its equivalent to Maui's famous Hana highway—much shorter of course. We drove to the end of the road at Halawa Bay Beach Park. Due to time constraints we did not get to take the hike inland to the waterfalls. There are a couple other pics from the drive to Halawa in my first and second Molokai posts below—e.g., the jetty & me on the rocks. (Click pics to embiggen slideshow)

Pacific Paradise, Pt. 4

Kalaupapa Peninsula is, as the name suggests, a peninsula approximately 2.5 miles by 2.5 miles on the north coast of the island of Molokai, Hawai'i. It juts out from what are purportedly the highest sea cliffs in the world. It was formed when one such cliff sheared off and a volcanic peak arose from the bottom of the ocean millions of years ago. There are only three ways to get there: fly, ride a mule, or hike down the steep three-mile trail. Either way, you need specific permission. (I'm informed that a barge arrives every July as well, bringing supplies to the residents). Once there, there is a four-hour guided tour.

We chose to hike down the 1760' cliff face. Each of the 26 switch backs, thankfully, is numbered. Going down is murder on the knees—because you are, essentially, braking with each step. Going up takes a toll on your thighs and cardio-vascular system. We figured the hike was the equivalent of climbing down then back up a stairway to the top of a 200-story skyscraper—in the tropical heat and humidity.

Kalaupapa was formerly a leper colony. Folks with the disease were shipped here from all over the world and left to fend for themselves. It was brutal until a kindly priest and a dedicated nun brought consolation and community, treating those afflicted like human beings. Of course, leprosy—now known as Hansen's Disease—has been curable for many years. Now, the peninsula is a National Historical Park. And, quite possibly one of the most beautiful spots on earth. Below are some pictures from our hike (click pics to embiggen slideshow!):

Pacific Paradise, Pt. 3

More from Molokai. (as ever, click pics to embiggen slide show)

We stayed in a small condo complex out on the West End, facing Oahu (you can see how small it is from the plane shot in my first Moloka'i post). There were four, one of them abandoned. The beaches were empty and damn near perfect. I hiked north along the shore  from our place past pristine, abandoned beaches and across what appeared to be an abandoned golf course gradually being reclaimed by the island. At one time, it must have been a beautiful place to play (if you like that sort of thing), and I understand the PGA used to hold events there. But the developers and managers faltered in the first decade of this century, and now its only denizens are wild turkeys, Axis deer (aka barking deer or chital, a gift in the 1860s to the King of Hawai'i for his hunting pleasure), and mongoose—all also invasive species. I kept asking myself as I walked: Is this the future of our country if a certain developer gets his and his friends' hands on our pristine public lands?) As blogfriend BDR likes to say: "metaphors abound."

Pacific Paradise

I apologize for neglecting you, oh blog o' mine. It's been a busy few weeks, with travel, a graduation, moving, and now wedding planning. I've got a few minutes now to share some pictures from my trip to Hawaii. My eldest kid aka Wisdomie graduated from UH-Manoa, and we spent a week on the island of Moloka'i. It's the smallest of the so-called 'major islands' (~38 x 10 miles) and was once home to a notorious leper colony—about which more later. Yeah, so if miles of perfect, deserted beaches and moderate to moderately strenuous hiking through tropical rainforest or on the world's highest sea cliffs and scuba diving on absolutely pristine reefs isn't your thing, then maybe Moloka'i isn't for you. Oh, and there's not a single stoplight on the entire island.

After a 9-hour flight, 6 of which was over water, Honolulu is a welcome sight! (Note the banking of the clouds above the mountains. That's a recurring image on the islands.)
You know you're in Hawaii when...

This Week in Water

Earth Day, 2016. Greetings! Let's see what's happening these days with our planet's most precious resource.

As much as 93% of Australia's Great Barrier Reef, the largest living structure on Earth, is experiencing coral bleaching—the worst on record—due to increased ocean temperatures.

Experts in the field are predicting that if earth's temperatures continue to increase, unprecedented rising sea levels and devastating superstorms from melting ice in Antarctica and Greenland will have destabilizing effects on climate and civilization. Current models appear to be far too conservative.

Arctic sea ice levels are lower than they've ever been after a historically warm winter.

Melting ice sheets are causing the position of Earth's axis to shift—which could magnify the effects of climate change as global temperatures get hotter, weather events become more extreme, and sea levels rise.

Some are suggesting to pump seawater to the surface of Antarctica to increase the size of the ice sheets and, theoretically, slow or even halt rising sea levels—at a tremendous cost.

One of the strongest typhoons on record, Fantala, struck the Indian Ocean.

More than 80% of the water in rural China is unfit for drinking due to contamination from industry and farming.

Are whale sharks dying out?

Pacific bluefin tuna population has dropped 97% from historic levels due primarily to overfishing.

Nearly 40% of the population of Somalia is suffering from an extreme drought that is fast becoming a humanitarian crisis. Ethiopians are feeling its effects as well.

Criminal charges—purportedly the first of many—have been filed in the ongoing Flint, Michigan, drinking water crisis, though remediation has yet to happen.

An Italian team has arrived to help repair the Mosul Dam in Iraq which threatens to collapse, potentially killing millions.

Is the most important river in the Western U.S., the Colorado River, dying a slow man-made death?

The level of Northern India's groundwater is dropping approximately one foot per year due to overuse.

The White House held a summit meeting on March, 22, 2016, to raise awareness of water issues and potential solutions in the U.S., including crumbling water infrastructure.

Can a biodegradable, algae-based bottle help end the world's plastic addiction?

And finally, the U.K. science minister "torpedoed" 'Boaty McBoatface' as the name of its new $300 million Arctic research vessel much to the chagrin of the thousands of people who voted for the name in a much-ballyhoed internet poll.

The Geometry of the Imagination

For you creative types or for those of you who find your imaginations limited, here's a formal exercise* to help you stretch your brain.

Imagine a point. In geometry, a point is merely a location. It has no size or dimension. Let's call it P.


Simple enough. Now, imagine a point moving from one location to another. Two points describe a line that extends through both of them infinitely in two directions; it has length. Call it Line AB. Length is the first dimension.


Add a third point that is not in line with AB, call it C. Or, imagine Line AB moving in a perpendicular direction through Point C. That describes a plane which, like the line extends infinitely in two dimensions: length and width. Call it Plane ABC:



So far so good. Now, imagine a fourth point which does not lie on Plane ABC. Visualize Plane ABC moving as a whole through this point. This fourth point adds the element of depth, describing the third dimension of space.


So far, our little formal exercise has been fairly intuitive. Every school kid understands how this works because, for one thing, our bodies describe a space—as does our expanding universe. Now, however, things become less obvious.

Imagine another point, a fifth point through which this three-dimensional space itself (which, I must remind you, like its subsidiary dimensions is infinite in every direction) moves as a whole. This is difficult to do because we have no way of formally representing this motion.

Let's simplify. The most efficient description, or model, of a finite space (or a solid) is a tetrahedron, a three-sided pyramid. Four points.



Imagine holding a solid tetrahedron in your hand and tossing it in the air and catching it. See it tumbling through space, up and back down. Now, visualize the entire tumbling arc, from toss to catch. This describes an event in time, the fourth dimension.

Of course, we must expand our model as we have each of our other dimensions and recognize that time is infinite and unbounded. And, as with our other dimension defining points, lines, and planes, we recognize (a) that time exists both within and throughout space and (b) that infinite three-dimensional space also moves through eternally extended time—much like our odd-shaped triangular ball above.

Have we stretched our imaginations? Yes. Are our brain muscles feeling sore like our arm muscles after lifting weights or our leg muscles after running? Sure. Dare we dare to imagine more? Let's.

We've imagined a model of infinite space moving through eternally extended time. The first thing we intuit about this space-time model, though, is that time seems to move in only one direction. Forward. Even sitting still, perfectly motionless, we move forward through time (and, technically, space! See my serial post entitled Being v. Becoming under Pages in the right-hand column). We time-travel (the relevant post from my series) at a relative rate towards what we call the future, never backwards toward the past. Why is this? It is for the same reason a point moving from A to B defines only a line, or a moving line describes only a plane, or a moving plane delimits space. As spatial beings, our experience of time is dimensionally limited. We exist in space-time and our perceptions are limited by its geometry.

But (and the "but" is always the engine of the imagination, isn't it) can we imagine what might exist outside of time? Can we conceive of a fifth dimension? A further point that we cannot intuit, one beyond space, time, and space-time, but through which infinite space and eternally extended time might move as whole?

Let's go back to our model: the tossed and tumbling tetrahedron. We've watched as it grew from a mere point through the dimensions to a line to a plane to a space. Now we've seen its arc from beginning to end describe an event in time. We've noticed that this event only happens in a forward sequence from toss to catch. (And we recall that it is at once happening in space-time and, for our purposes, is a finite model of infinite space moving through infinite time.) If we press a bit and let our imaginations run, we can theorize what a dimension beyond this event might have to be like. This would be a dimension where the toss has not yet happened and yet it has already happened and, what's more, that it is always already happening—forward and backward.

Just as a point dissolves into a line, and a line into a plane, etc., time dissolves into an eternal now (to borrow a phrase [but not a concept] from 20th Century theologian Paul Tillich). As we've noted, there is an infinite length of time: as space expands infinitely, time extends eternally. But this is different from an eternal now in which this infinite extension has already happened.

In this fifth dimension, space does not exist, yet it is infinite and everywhere. Time has not yet begun, yet it extends eternally, and is always already happening—forward and backward.

Now, to try to keep our feet on the ground, we must ask whether such a fifth dimension exists, or is it only something we've imagined? Well, if it's something we can only imagine, then our exercise has been successful! We've expanded our minds, and opened new dimensions of thought.

The question whether there is some sort of fifth dimension beyond time and space and space-time is probably not one we can answer. We must leave it to our imaginations. Though it is fair to say that such a dimension is a possible inference from the geometric argument of dimensional expansion. (As are further dimensions in which eternities themselves dissolve.)

It could be, however, that we're asking the wrong question. Existence might be something that can happen only within the limits of the space-time dimensions. It is not a relevant category of the eternal now. It obtains only where there are limited durations of concrete spaces. It pertains only to realms where what we know as dimensions happen. Existence itself only exists where there is, in fact, geometry.

Imagine that!

Mr. Ginsberg led off the session with a meditation encouraging us to breathe deeply and while doing so ply our imaginations in a similar manner as described above.
