As you all know, the Romans journeyed to the British Isles around 100 BCE, thought it nice, and returned in force 100 years later. They remained until around 450 CE, when they were informed they should 'look to their own defenses'. The Roman Empire could no longer support it's various colonies around Europe.
While in Britain the Romans built roads, various viaducts to transport water, and houses, villas. Many of the villas were large, and had creature comforts such as running water, and sometimes heating systems and elaborate bath houses.
During the period (I'm getting to the point here, albeit slowly) 400-550 CE, the British Isles were either being invaded or settled, depending on your viewpoint, by some other cultures: the Angles, Saxons, and Jutes, coming from various points on the mainland of Europe. At the same time the Roman population was leaving, or dying out in Britain, leaving these elaborate living quarters.
Archeologists, discovering the remnants of these structures around 1800 years later, found what seemed to be a curious thing......they had not been lived in by any of the new cultures that came after the Romans left. The Angles and Saxons lived in dirt and wood structures, with no amenities.
The conclusion is that neither the Angles or Saxons could figure out how the abandoned structures worked. Therefore they could not maintain them, or fix them if something broke. The road disappeared over time, the structures largely sunk into the earth. A few viaducts remained, being made of stone. The newer cultures were a regression from the knowledge and social structure that preceded them. I think there are similarities to the Saxons scratching their heads over the Roman baths, and our world today.
The events in the Middle East, with the Islamist loonies destroying the artifacts in Nimrud are a obvious example, but I'd rather stick closer to home for the moment. We've got our own examples of what might be thought of as reverse entropy, if one were to pervert the 2nd law of thermodynamics. Since there are so many examples of what I'm going to call anti-science, I'll just refer to two things, Evolution and Climate.
Roughly half of Americans don’t
accept evolution. (I don’t like to use the phrase “believe in”
evolution; it’s like choosing whether or not to believe in gravity.)
Darwinian evolution (including the modifications biologists have brought
forth over the years) is the only explanation that scientists have
found for the relevant data. The wealth of data is so vast, evolution
explains these data so well, and nearly the entire community of
professionally trained biologists is so persuaded by this explanation
that it is unlikely any other explanation will come along to supplant
it. However, as good scientists, we remain open to the possibility of a
better idea developing to explain the data. Until it does, there is no
scientifically valid reason to hold any other view than that our species
(and all other species of animals, plants, fungi, and bacteria) have
arisen on the planet through the process of evolution.
But more than that, this denial of evolution speaks to an
anti-intellectualism, a brand of antiscience that contributes to human
suffering. If people can deny evolution, which is well supported by
scientific evidence and widely accepted by the professional scientific
community, then they will deny any scientific findings they dislike. The
same methods and insights that have informed how scientists understand
the movement of the planets, how molecules work, and what medical
remedies are most effective have also informed our understanding of
evolution. We can choose to cherry pick only the data that support a
particular bias about how the world works, but how does that help us if
the world does not work that way?
A Gallup poll in 2012 showed that 58% of republicans believe that god created humans in their present form less than 10,000 years ago.
It's the same with human-caused climate change. There is nearly unanimous consensus among scientists that it is real, and one of the most important things we need to address. Less than 50% of US citizens believe it is real. Over half of the republicans in congress deny the science is real. In the senate, it's nearly 75% of the GOP deny the science.
We're leaving out the attacks on education, though it figures highly in the above.
We're left to wonder are we like the Saxons, too uneducated to understand the culture that preceded them, or is this something less benign than being dumb? Whatever it is, it has us at the point where we are less advanced when measured by progress from one year to the next. In science, particularly aerospace, we cannot match the feats accomplished 40 years ago. Each year, fewer and fewer US-born students enter science graduate programs.
The US is unraveling at a stunning speed, and at a staggering decree. The decline is breathtaking, and the prospect is dim. Especially when what we seem to depend on to rescue us is faith.
