The Not-So-Dark Ages

The idea of the "Dark Ages" is closely tied to one influential figure: Francis Petrarch, a 14th-century Italian poet, scholar, and humanist. Widely regarded as one of the greatest intellectuals of his era, Petrarch looked back on ancient Greece and Rome as a brilliant age of learning and culture. By comparison, he believed that the centuries following the fall of the Roman Empire—including his own time—were marked by decline and intellectual darkness.

Petrarch was optimistic that this period would eventually end. "This sleep of forgetfulness will not last forever," he wrote. "When the darkness has been dispersed, our descendants can come again in the former pure radiance." 

His admiration for the classical world helped inspire the humanist movement of 15th-century Italy, which in turn fueled the Renaissance. Because of Petrarch's influence, the idea of a long "Dark Age" became widely accepted by both scholars and the public for centuries.

The term "Dark Ages," however, has also been used in a more limited and neutral sense. In the late 16th century, Italian cardinal Caesar Baronius used the Latin phrase saeculum obscurum ("dark age") to describe the 10th and 11th centuries. His point wasn't that the period was uncivilized or culturally barren. Instead, he was referring to the lack of surviving written records from those centuries.

The Roman Empire produced an extraordinary number of official documents, histories, and other written records. After the empire's collapse, far fewer documents were created and preserved for several centuries. As a result, historians often know much less about the Early Middle Ages than they do about Roman times. In that sense, the period can be considered "dark" not because nothing important happened, but because fewer historical sources survived to illuminate it.

When Rome collapsed, Europe was left without a central authority to keep things running. Step in: the Christian church. Monasteries quickly became the ultimate hubs for literacy, learning, and the arts, with monks preserving knowledge and funding artists. It wasn't long before the very first universities were born, keeping higher learning alive and kicking.

Meanwhile, over in the Arab world, things were positively glowing. The 8th through 13th centuries marked the Islamic Golden Age—a massive boom in science, economics, and culture that produced some of the smartest minds in human history.

The "Dark Ages" basically overhauled everyday life. Farming got a massive upgrade: The invention of crop rotation, the heavy plough, and the horse collar transformed agriculture overnight, allowing farmers to feed more people than ever.

Energy went green (literally): Watermills and windmills started popping up everywhere, completely revolutionizing how power was generated. Gothic architecture began towering over cities. Early musicians finally refined musical notation so songs could actually be written down and shared.

European battlefields saw the arrival of heavily armored cavalry and the scary new appearance of early cannons. Major, groundbreaking progress was made across mathematics, astronomy, and medicine.

Most modern historians now reject the pejorative “Dark Ages” label, although it continues to be used in popular culture. Typically, the term “Early Middle Ages” is now used to describe the era, or, in a wider sense, the “medieval era.” While the period certainly had its challenges, it was far from the uniformly bleak and intellectually barren time that historians once portrayed. It was, in fact, a crucial transitional era that bridged classical antiquity and the Renaissance, laying the groundwork for developments that shaped the future.

100 Million Dollars or Volts

The last time I bought a lottery ticket - and lost - a friend said, "You have a better chance of being hit by lightning."

I checked. The odds of winning the Mega Millions jackpot — matching all five main numbers (1–70) and the Mega Ball (1–25) — are 1 in 302,575,350. The odds of being struck by lightning in America in a given year are one in 1.2 million. You have a much better chance of being hit by lightning. It goes against my limited knowledge of statistics, but the odds are fixed, and the probability is the same regardless of the jackpot size. It only grows if no one wins, but the odds remain unchanged.

And that lightning statistic made me think about what it must feel like to be struck by lightning. How would that experience change a person’s sense of chance, or fate?

The article I found, "What 100 Million Volts Do to the Body and Mind," opens by saying that: 

There is no easy analogue. A defibrillator delivers up to 1,000 volts to a patient’s heart; inmates executed by electric chair typically receive about 2,000. A typical lightning strike, by contrast, transmits 100 million volts or more. But lightning races through the body in milliseconds, and therefore often spares it. Some people black out instantly upon being struck. Others recall the moment vividly, as if in slow motion: the flash of light whiting out all vision; the sound, which many survivors say is the loudest they’ve ever heard. The pain, for some, is excruciating, yet others feel no pain at all. “It felt like adrenaline, but stronger,” one survivor reported. “I felt an incredible pulsing,” another said, “a burning sensation from head to toe.”

I did find some references to people who were hit by lightning and survived, telling their stories. There are some shared changes in their attitudes and beliefs.

For those survivors, events that once felt arbitrary or random now feel patterned, or vice versa. A near‑miss accident can make someone feel the world is full of fragile contingencies; a serendipitous meeting can make randomness feel strangely benevolent. You don't have to get hit with 100 million volts. This might happen if you had a near-miss auto accident that could have killed you.

Any kind of powerful experience can lead people to notice coincidences they previously ignored. The world seems to “speak” to them more often. Chance becomes less abstract and more embodied. It is not so much a statistical numbers idea but a lived one.

Fate is the story we tell about why things unfold the way they do. Some of us believe in Fate. Some do not. A near-miss experience might change that belief, causing someone to reinterpret past events as stepping stones toward the present moment. Fate becomes a retroactive storyline.

The experience may create a sense of direction or purpose, even if none existed before. “This happened so I could…” Call it teleology. That is the idea that things have purposes, goals, or ends toward which they naturally move. You might find yourself explaining something by the outcome. "It was just meant to be" rather than by the mechanism that actually caused it.

Aristotle described nature as full of purposes. The heart exists to pump blood. Rain falls to nourish crops. But modern science accepts only functional explanations. Yes, the heart pumps blood, but no, to seeing the cosmic intention of “rain falls so crops can grow."

Who Came Up with Clockwise and Why?


If you grew up in the world before digital timepieces, you learned about the time-telling "hands " on an analog clock on the wall. The hands (big, little, even second hands) moved "clockwise.” Did you ever wonder why the hands moved in a particular direction?

Go back before clocks, gears, and pendulums, to ancient civilizations in Egypt and Mesopotamia that tracked time using sundials. All these cultures were in the Northern Hemisphere. That means the sun rose in the east, arched across the southern sky, and set in the west, and that means the shadow cast by a sundial naturally traveled in a loop: west to north to east.

If those ancient civilizations and their sundials had been in the Southern Hemisphere below the equator, the shadow would sweep in the exact opposite direction.

Clocks were invented in Europe during the 13th and 14th centuries, so to make these new machines intuitive, clocks were engineered with mechanical hands that mimicked the familiar, left-to-right sweep of the local sundial shadows.

European clockmaking dominated and became the global standard when clocks were exported to the Southern Hemisphere.

One rare exception to this includes the Old Town Hall in Prague, which runs "backward," mirroring the right-to-left direction of Hebrew script and local vertical sundials. I've seen this beautiful clock in person, and it always gathers a crowd of tourists who marvel at its movements of figures, but most people never notice the conterclockwise of it.


The Cranium Nebula

It looks like a brain, complete with what appear to be left and right hemispheres. It is actually a dying star blowing off a shell of gas, and within that shell, a cloud of various gases. The dark lane that divides the sides of the “brain” may be related to an outflow from the central star.

In near-infrared, the nebula’s outer bubble has a white edge and its inner clouds are orange, with a distinct dark lane cutting vertically through the center. Stars and background galaxies appear around the nebula and through the outer bubble.

What’s next for this star will depend on its mass, which is yet undetermined. If it is a high-mass star, it will explode in a supernova. If it’s less massive and more Sun-like, it’ll keep shedding layers until only its core remains as a dense white dwarf star.
