Amazon River Has No Bridges
The Amazon River is the world's second-longest river and one of the planet's most significant waterways. It contains more fresh water by volume than any other river, is home to the world's largest species of river dolphin, and hosts 100 species of electric fish and up to 60 species of piranhas.
Yet, despite its many and varied qualities, there is something that cannot be found on the Amazon River: bridges.
Given the Amazon flows through three countries (Peru, Colombia and Brazil) and more than 30 million people live in the river's basin, according to the World Wildlife Fund(opens in new tab), it seems somewhat improbable that no bridges span the river. So why is this the case? Are there fundamental difficulties with building such structures in a rainforest containing swamps, extensive wetlands and deep, thick undergrowth? Are there financial barriers? Or is it simply not worth the effort?
When compared with some of the world's other most recognisable rivers, the Amazon's lack of bridge crossings is an oddity. There are about nine Nile-spanning bridges in Cairo alone; more than 100(opens in new tab) bridges have been completed in the last 30 years across the Yangtze, Asia's premier river; while Europe's Danube, which is only one-third as long as the Amazon, has 133 bridge crossings(opens in new tab).
So what's the deal with the Amazon?
"There is no sufficiently pressing need for a bridge across the Amazon," Walter Kaufmann, chair of Structural Engineering (Concrete Structures and Bridge Design) at the Swiss Federal Institute of Technology (ETH) Zurich, told Live Science in an email.
The Amazon, for much of its 4,300-mile (6,920 kilometers) length, meanders through areas that are sparsely populated, meaning there are very few major roads for any bridge to connect to. And in the cities and towns that border the river, boats and ferries are an established means of moving goods and people from bank to bank, meaning there is no real need for bridges to be built, other than to make trips slightly quicker.

Rennaisance Man Da Vinci
Leonardo Da Vinci—arguably one of history’s most resourceful geniuses—was the unwanted result of casual sex between a local peasant girl and a young man from a prosperous family. Both were from Vinci, a small hill town not far from Florence with winding cobblestoned streets, wooden shutters, and spindling trees. It was in this village that Leonardo was conceived and surrendered by his mother as an infant to his father’s family.
In an era referred to as “the age of bastards,” Leonardo’s illegitimate birth would not have involved any injury to his future: his eighty-year-old paternal grandfather set down a few basic details unapologetically.
“A grandson of mine was born, son of Ser Piero, my son… his name was Leonardo.”
The entry of birth, through brief, was followed with the name of the priest who baptized the newborn and a list of the people present at the ceremony.
Leonardo’s grandfather had been a notary of repute, as had his great-grandfather. Leonardo’s father also entered the profession and married the daughter of another notary family. While the couple established their residence in Florence, Leonardo remained in Vinci with his grandparents, whose stolidly middle-class household provided a stability of routine but no formal education. The lack of structured schooling makes the abundant body of Leonardo’s entirely self-taught knowledge almost unfathomable.
He was an irrepressible force of nature and fortunate enough to have been nurtured in a time that was daring his country further and further. Revolutions in the sciences and the humanities tend to occur in clusters of extraordinary individuals: Giotto, Michelangelo, Galileo, Dante, Machiavelli, Marco Polo, and Columbus—all were Italians, each with a key role in paving the way for the future.

Mayan City Discovered
Archaeologists working in the Yucatan region of Mexico have revealed the remains of a centuries-old Mayan city, local media reported on Friday.
The city of Xiol — which means "the spirit of man" in Mayan — is believed to have been the home of some 4,000 people between 600 and 900 CE, during the late classic period.
The area was first uncovered in 2018 on a construction site for a future industrial park close to the town of Merida on Yucatan's northern coast. Archaeologists from the National Institute for Anthropology and History (INAH) then took over the site.
The site is of particular interest due to its Puuc style architecture — famously used for the Chichen Itza pyramid — which is more typically found in the southern part of the Yucatan region.
The archaeologists also highlighted the array of palaces, pyramids and plazas found at the site as well as evidence of various social classes residing there.
"There were people from different social classes ... priests, scribes, who lived in these great palaces, and there were also the common people who lived in small buildings," Carlos Peraza, one of the archaeologists leading the excavations, said. READ MORE...

Unintended Consequences
These consequences can be defined as: In the social sciences, unintended consequences (sometimes unanticipated consequences or unforeseen consequences) are outcomes of a purposeful action that are not intended or foreseen. The term was popularised in the twentieth century by American sociologist Robert K.
EXAMPLES
1. “Three strikes” laws may actually be increasing the murder rate, and not decreasing it.
2. Seat belt laws increase the number of car accidents, and increase pedestrian and cyclist deaths.
3. Banning the insecticide DDT almost certainly has led to more deaths, not fewer.
4. Teaching children not to talk to strangers (e.g. the “Stranger Danger Campaign”) may be making them less safe, not more safe.
5. The lengthy and costly FDA approval process might be causing more, not fewer, deaths.
6. Government regulations that reduced logging in America’s national forests (e.g. to protect the threatened northern spotted owl) may have resulted in more acres of forest being harvested worldwide, not less.
7. Increasing state cigarette taxes may significantly decrease government tax revenues, not increase revenues as expected.
8. Tariff on imports are passed in order to protect domestic industries and jobs from foreign competition, but often end up costing more American jobs than are saved by protectionism.
9. Vegetarianism may lead to an increase in animal deaths, and not a decrease.
10. Thanks to the efforts of animal rights activists, horse slaughter is now banned in the US. But that ban is very likely making the treatment of horses worse, not better.

Trans is Trans
I have no problems with males wanting to be females and/or females wanting to be males... that is their choice, not mine... and, why they made their choice is their decision as well and they have no reason to share... but, I do not think that trans males should be allowed to physically compete in sports with females...

Living in the Valley
I have lived in the East Tennessee valley since 1990 or roughly 32 years at the end of 2022, relocating in January. I have lived in Greeneville for several years, then Morristown, then Chattanooga, then Dandridge, and finally Jefferson city for the last 20 years. Our home is located in a rural community just a few miles outside of the city proper and I have two large lakes on either side of me (10 miles away from the house), Douglas and Cherokee. Both of these lakes are suitable for boating and fishing; and, there are numerous areas where families can camp, hike, and/or picnic.There is a Walmart Super Center 2 miles away from the house and across the street is a fitness center that I can use for free because of my health insurance company. There are half a dozen gasoline stations less than 2 miles away from my house. Morristown is 10 miles northeast of my location and offers several restaurant chains like Texas Roadhouse. Knoxville is about 35 miles southwest of my location and offers dozens of restaurants and movie theaters for entertainment.UT Medical Center is 31 miles from the house and we have two other large hospitals, Tennova and Ft. Sanders all of which have teams of physicians educated and trained at some of the best hospitals in the country who have chosen to live in East Tennessee. Vanderbilt in Nashville is only 3 hours away in case someone prefers that name, although Vanderbilt-trained physicians work and live in Knoxville as well.The first two years of college is free to any resident of Tennessee and we have numerous community college, small colleges, and universities along with the University of Tennessee, and the association of universities house at Oak Ridge National Laboratories. Knoxville airport connects with all the major hubs and has several direct flights to New York City each day. It is a 30 minutes flight to Atlanta.
The State of Tennessee collects no state income tax but has a 7/8% sales tax and the cost of living as a result of moderate wages is or was 10-15% less on average than anywhere else in the US. Like all states, COVID has taken its toll on the cost of living in the East Tennessee area. But, the quality of life which is laid back and void of a lot of crime, violence, and traffic is an ideal place to live if that is your mentality.
Before 1990, I lived in the Piedmont area of North Carolina between Greensboro and Durham and while the area was beautiful, it does not compare to the beauty of the Tennessee Valley and the Smoky Mountains. Not only is the traffic in that area terrible and the volume of people cause long lines to develop in stores, but the opportunities for employment are also better in East Tennessee. One of the reasons why I left North Carolina was that my skills put me into a "dime a dozen" category whereas in Tennessee, I was unique or in a category with only 1-2 others... making employment and wages very easy to attain. The downside was that wages after entering a company did not grow as fast as they did in North Carolina but our prices did not grow as fast either.Religious and Spiritual Beliefs
SUFFERING (and pain) seems to be a pretty consistent theme among religions and most spiritual beliefs...
In Christianity, our suffering (and pain) was done by Jesus so that we would not have to suffer, but then entry into the kingdom of God could only take place in you believed in Jesus.
Still, there was suffering...
In Buddhism, suffering is also a key component that revolves around life's 4 truths:
- all of life is based upon pain, suffering, and sorrow
- the cause of suffering are our illusive desires
- the cure to suffering in to overcome desires
- we overcome desire by following a 8-fold path
In Hindu, suffering is again present...
- an essential life (Karma) revolves around good and suffering
- religious duties can help you acquire merit for the next life
In Christianity, one seeks to enter the kingdom of God after death but it Hindu and Buddhism, one seeks to become unified with the universe. In essence, all three of these are the same.
These three spiritual beliefs are different and yet they all reach the same conclusion after death... So, death is the ultimate similarity and is actually what happens to all of us regardless of what we believe. It seems that becoming one with the universe is our justification for death.
Regardless of what kind of life we live, we all die... Death is certain and absolute... but, if one has spiritual faith, then death becomes more than being in a state of nothingness... or as some call it a void.
Are we just rationalizing our FATE?
Loogically, there has to be a creator... and, while that seems logically true... who is the creator's creator? At this point, our logic, like death, cease to exist and we are left with a question that cannot be answered except through spiritual faith... or, is this what they call circular logic?
Nonetheless, it is mental quicksand.
Neolithic Settlements in Turkey
Istanbul archaeology professor Necmi Karul picks his way as nimbly as a gazelle along the hilly back slope of Karahantepe. A monumental Neolithic site near the Syrian-Turkish border, Karahantepe has turned what archaeologists until now believed about the evolution of human sedentism on its head.
It, along with the nearby Gobeklitepe Stone Hill site, is considered one of the first permanent settlements. They have brought into question the process of organized human society, suggesting that it was established before the emergence of agriculture, and included some kind of cultic or communal rituals.
Karul points out spots where some 11,000 years ago Neolithic humans carved out huge blocks of limestone and somehow brought the heavy pillars to the other side of the mound. After being carved with images of animals and humans, these blocks were placed in concentric circles in what he calls “special buildings.”
Walking along the sloping hillside Karul also points at stones jutting out from the earth in a circular pattern. Underneath, he said casually, there are the same thousands-year-old monumental pillars that have been excavated just on the other side of the mound.
He said 250 such pillars visible on the surface have been identified, and some 60 pillars have been found in the excavations. READ MORE...
Ancient Settlements Discovered
134 ancient settlements have been found during a survey of the region north of Hadrian’s Wall in the United Kingdom.
These locations belong to Indigenous communities that date to the Roman occupation. The findings were published in the journal Antiquity on Tuesday.
Following Hadrian’s ascension to the throne in AD 117, he built a wall unlike any other in the Roman world, a wall that was a tangible representation of Rome’s might, solidifying the Roman defense strategy and indicating the Empire’s most northern limit.
Hadrian’s Wall (Vallum Aulium) was a Roman defensive structure that extended 73 miles (116 kilometers) from Mais (Solway Firth) to Segedunum (Tyne River) (Wallsend).
In AD 142, Emperor Antoninus Pius extended the frontier further north and constructed the Antonine Wall (Vallum Antonini). This wall ran 39 miles (62.7 km) and annexed lands formerly ruled by the Damnonii, Otadini, Novantae, and the Selgovae tribes.
Earthworks can be seen at the Woden Law hill fort in southern Scotland, close to a Roman road, with the remains of Roman camps less than a mile away. Antiquity
Most research into the area has focused on the Roman side of history to learn more about the roads, forts, camps, and iconic walls they used in their attempts to control northern Britain.
Manuel Fernández-Götz, head of the Department of Archaeology at the School of History, Classics, and Archaeology at the University of Edinburgh in Scotland, is interested in uncovering the other side of the story: how Roman rule affected the lives of Iron Age Indigenous communities in Britain.

Treasures Found in Curious Places
It’s quite the story, but finding hidden treasures in surprising places isn’t as rare as you might imagine. Here at Atlas Obscura we love these kinds of stories. So in honor of the return of Dennis, we went digging through the archives to uncover some other stories of priceless artifacts discovered in unusual places.
A Mosaic From Caligula’s Ceremonial Ship, Turned Into a Coffee Table (image above)
The striking piece sat in a Manhattan apartment for decades, until the Italian military police’s Art Recovery Unit showed up.
Antique dealer Helen Fioratti had no idea the mosaic that sat in her Upper East Side apartment had been dredged up from a mysterious Roman barge in Lake Nemi, Italy. After buying the red-and-green mosaic in Europe, Fioratti spent thousands of dollars shipping it home to New York and converting it into a coffee table. For 45 years, the table sat as a beloved accent piece, garnering many compliments from visitors, Fioratti told The Associated Press.
