Time: Liquid, Eternal, and Vacation

Rome’s emperors spent time, money, and the lives of thousands to ensure their immortality.

Time’s a funny thing. On one hand, it seems so absolute, unalterable, a one-way arrow to which we are all irrevocably tied.

On the other hand, we all perceive it differently. For example, I know time as a pilot—tangible, measurable, available in limited, finite quantities. Here in Rome, the “Eternal City”, I find ample evidence of those who judged it differently. They considered themselves exempt from its constraints. Their best efforts at immortality, however, served only to produce tourist revenue and archeological delight. read more ...

How the Summer Solstice Reveals the Big Picture

Because the Earth’s axis is tilted, it passes 4 special points every year. Image credit: By Tauʻolunga – Own work, CC BY-SA 2.5, https://commons.wikimedia.org/w/index.php?curid=927635

I’m on an overseas assignment this month. Yesterday morning, when I walked outside onto the porch, something felt strange. I stepped to the edge and looked up at the overcast sky. A bright area of the clouds bathed my face with heat. Bright heat? How could that be? I faced north. I opened my iPhone’s compass app. Checked. Yep, that was north. But, the Sun never shines from the north. Unless…

I checked the time—10:30 AM. Then the date—June 20^th. I knew I was north of the equator, so only one explanation remained. What I observed meant I was standing south of the Tropic of Cancer. Sometime during the next day or two, the Earth, on its way around the Sun, would pass a point called the Summer Solstice. read more ...

Lagrange Points—Orbits to Nowhere

Milky Way in night sky above a lake shore — Without gravity, everything we see here—water, trees, rocks, and stars—would fly apart

Gravity glues our universe together. Without it, neither we nor any life could exist. The Earth spins at just over 1,000 miles per hour at the equator. Without gravity, anything loose on the surface like water, cars, picnic tables, and people would immediately fly off into space. Without gravity, Earth couldn’t keep an atmosphere. As soon as it drifted free from the surface, the fierce solar wind would blast it away. Without gravity the Sun itself would expand, dissipating in a fine, cold mist of dust and gas. read more ...

Reentering the In-between Place

computer map of airliner flight path over canada — When I lifted the window-shade we were just leaving eastern Canada for the icy north Atlantic.

The cabin’s dark. All shades down. I’m up from my middle seat in a B-777 mid-section, pacing the aisle amidst a couple hundred sleepers. Like river rapids, air rushing over our fuselage blankets all other sounds and provides a steady background for the occasional snort, sneeze, or snuffle. I feel alone in the silent crowd. Unnoticed. Unseen.

I move to the open space dividing Economy from Business Class and stand before the sealed exit. Carefully I stoop down, shielding the tiny window with my body. I slide my thumb under the lip of the plastic shade and slowly push up. A half-inch. A full inch. A thin, brilliant wedge of sunshine explodes. Dare I open it more? I must. Cloud tops tantalize, draw me. I look at the slumbering forms to my left. All wear eye masks. No one moves. Emboldened I push again. A two-inch slot reveals the panorama of broken clouds offering small holes to sea and ice-covered mountaintops below. At thirty-five thousand feet, we’re leaving the eastern shores of northern Canada for the icy north Atlantic. read more ...

How I Learned to Keep My Balance and Fit it All In

Smiling man loading cargo into a single engine airplane — Panchito loading a C-185, leaving just enough room for me to fly it safely.

Preparing for a month-long work trip out of the country inundated me with too many extras, too many surprises. No time left to work on my novel (The Perelandra Paradox), pitch the memoir (Sky Creature), reprint and re-market my previous book (Call For News), and, oh yeah, write this post. I was feeling overloaded and out of balance. Reminded me of flying.

Every manufacturer determines the maxim allowable takeoff weight for every aircraft they produce using four factors:

1. The engine’s power: The engine(s) must produce enough power to move the aircraft fast enough to make the wings work.
2. The wing’s lift: The wings, given airflow, must produce enough lift to raise the aircraft off the ground.
3. The airframe’s strength: The airframe must hold its own weight, plus the fuel, cargo, passengers and crew in their designated places during taxi, take off, climb, maneuvering, descent, and landing.
4. The performance margin: The gross weight of the aircraft must leave enough margin for the airplane to be controllable throughout all of its expected motions in both still and turbulent air. read more ...
