A stunning theory claims that the Americas were discovered in Antiquity

Credit: thevintagenews
Among the many theories about which civilization first sailed to the Americas and discovered them, there is also the theory that the ancient Phoenicians were the first.

This theory became popular in the 18th century and is closely connected with the petroglyphs on Dighton Rock which are still of unknown origin. This theory is not quite as popular as the one that says that the Norse made the discovery first, but still, it is worth mentioning.

Back in the 18th century, a lot of scholars started to offer ideas about the true origin of the inscriptions on the rock. Ezra Stiles, a theologian, author, and also the seventh President of Yale College, claimed that the inscriptions are in Hebrew. Antoine Court de Gébelin, who is mainly known for the popularization of the Tarot, had his own idea about the rock. He believed that the inscription was made by Carthaginian sailors who commemorated their journey to the shores of Massachusetts.

In the 19th century, the theory that a group of Israelite people visited the New World was widely adopted in the Mormon community.

Later, Ross T. Christensen, an American archeologist, speculated that the Mulekites, who are mentioned in the Book of Mormon, were probably of Phoenician ethnic origin.


The Phoenician theory is also supported in a book written in 1871, by John Denison Baldwin, an American anthropologist. In Ancient America, Baldwin wrote,

“The known enterprise of the Phoenician race, and this ancient knowledge of America, so variously expressed, strongly encourage the hypothesis that the people called Phoenicians came to this continent, established colonies in the region where ruined cities are found, and filled it with civilized life. It is argued that they made voyages on the ‘great exterior ocean,’ and that such navigators must have crossed the Atlantic; and it is added that symbolic devices similar to those of the Phoenicians are found in the American ruins, and that an old tradition of the native Mexicans and Central Americans described the first civilizers as ‘bearded white men,’ who ‘came from the East in ships’.“

A stone tablet with an inscription that was supposed to be of Phoenician origin appeared in Brazil in the 1870s. The tablet was given to Ladislau de Souza Mello Netto, who was the director of the National Museum of Brazil at that time, and he immediately acknowledged the artifact as genuine. The inscription allegedly told the story of some Sidonian Canaanites who visited the shore of Brazil. It was later discovered that the symbols that appear on the tablet were variations of letters that appeared in different periods over a span of 800 years. It was impossible for all the letters to appear on the same tablet at the same time, so the artifact and the inscription were dismissed as fake.

In the 20th century, a few new artifacts appeared that again spiked the theory of Phoenician or Semitic discovery. One of these artifacts was the Bat Creek inscription. Cyrus Herzl Gordon, Near Eastern cultures and ancient languages expert, believed that the inscription of this tablet was in Paleo-Hebrew. Gordon thought that this was proof that Semitic people visited the continent prior to Columbus. Later, the Bat Creek inscription, together with another artifact called the Las Lunas Decalogue Stone, were proven to be forgeries and Gordon’s claim was dismissed.

In 1996, Mark McMenamin, an American paleontologist, speculated that Phoenician sailors visited the Americas around 350 BC. He based his theory on some gold stater coins that were allegedly made by the state of Carthage. On the back of the coins was a map of the Mediterranean and another land on the west, across the Atlantic. McMenamin interpreted that land as the Americas but later discovered that those coins were actually a modern forgery.

Another form of written evidence that slightly goes in favor of the arrival of Phoenicians in the Americas can be found in Ptolemy’s Geography. Lucio Russo, an Italian physicist, mathematician, and historian of science, analyzed Ptolemy’s book and noticed that he gives the coordinates of the Fortunate Isles.

The fortunate Islands were a group of legendary islands mentioned by various ancient Greek writers. Russo also noticed that the size of the world in Ptolemy’s Geography is smaller than what Eratosthenes measured. After he gave the same coordinates of the Fortunate Islands to the Antilles, the map irregularities in Ptolemy’s descriptions disappeared. According to Russo, Ptolemy could have known about the Antilles from his source, Hipparcos, who lived in Rhodes. It is possible that Hipparcos heard about the Antilles from Phoenicians sailors who controlled the western Mediterranean in those days. This is a far-fetched idea, but still, an interesting one.

Most of the modern-day scholars deny the idea that Phoenicians, Canaanites, or Carthaginians discovered the Americas first.

Ronald H. Fritze, an American historian, says that although it was technically possible for those people to reach the Americas, it probably never happened:

“No archaeological evidence has yet been discovered to prove the contentions of Irwin, Gordon, Bailey, Fell and others. Since even the fleeting Norse presence in Vinland left definite archaeological remains at L’Anse aux Meadows in Newfoundland, it seems logical that the allegedly more extensive Phoenician and Carthaginian presence would have left similar evidence. The absence of such remains is strong circumstantial evidence that the Phoenicians and Carthaginians never reached the Americas.”

Until some concrete evidence appears, this theory will remain only a fantasy

These are the books that Princeton, Harvard and Yale professors think you should read

When asked, professors at America's most prestigious colleges — those in the top 10, according to US News & World Report — shared with Business Insider the single book they think every student should read in 2017.

College professors dole out an incredible amount of required reading to their students.

But what if they could only choose one book?

When asked, professors at America's most prestigious colleges — those in the top 10, according to US News & World Report — shared with Business Insider the single book they think every student should read in 2017.

The topics of the books spanned issues from politics to social science to Shakespearean literature.

Read on to see what professors from schools like Princeton, Harvard, and Yale think you should read this year.

Jill Abramson, Harvard: 'The Paranoid Style in American Politics,' by Richard Hofstadter

Abramson, a former executive editor of The New York Times and current Harvard English lecturer, recommends students read Richard Hofstadter's "The Paranoid Style in American Politics," first published in 1964.

Amazon.co
Abramson says the book is "everything you need to know about the root of Donald Trump's rhetoric and fake news."

James Berger, Yale: 'Orfeo,' by Richard Power

James Berger is a senior Lecturer in English and American Studies at Yale University. He recommends the 2014 novel "Orfeo," by Richard Powers.

Business Insider
He implores students to read the book, explaining that:

"It is a story of music and genetics in our contemporary age of terror and surveillance. An idiosyncratic retelling of the Orpheus myth, an elderly avant garde composer who feels he has tried and exhausted every possible musical experiment, returns to his first love, biology, and seeks to inscribe a musical score onto the mutating DNA of bacteria. Yup.

"But his efforts are mistaken to be acts of bioterrorism, and so he flees into the 'underworld' of contemporary America, returning also to the various Euridices of his past. Amazing book —and you'll learn a hell of a lot about music, science, politics ... and even about Life!"

Eric Maskin, Harvard, and Maurice Schweitzer, UPenn: 'The Undoing Project,' by Michael Lewis

Amazon.com
Eric Maskin is a Harvard professor and received the 2007 Nobel Memorial Prize in Economics. Maurice Schweitzer is a professor of operations, information, and decisions at the Wharton School at the University of Pennsylvania.

Both chose Michael Lewis' "The Undoing Project."

David B. Carter, Princeton: 'The Strategy of Conflict,' by Thomas Schelling

David B. Carter is a politics professor at Princeton University. He recommended "The Strategy of Conflict," by Thomas Schelling, especially given the author's recent death. He said:

AbeBooks
"'The Strategy of Conflict' is both probably the best book ever written about conflict and still very useful and important for understanding strategic interaction among states (and individuals).

"It also happens to be a very well-written and readable book. I read it as a junior in college and it was instrumental in getting me interested in international relations more generally, and in understanding conflict behavior and strategy in particular. I know it is an old book, but think it is something that anyone would benefit from reading."

WJT Mitchell, U Chicago: 'A Theory of the Drone,' by Gregoire Chamayou

WJT Mitchell is an English and Art History professor at the University of Chicago.

The New Press
He recommends a book by French philosopher Gregoire Chamayou called "A Theory of the Drone," which attempts to understand how drones have revolutionized warfare.

Mitchell describes the book as:

"A very intelligent assessment of the new conditions ofdrone warfare in their implications for just war theory and notions of military valor."

Kenneth Warren, U Chicago: 'Racecraft: The Soul of Inequality in American Life,' by Karen E. Fields and Barbara J. Fields.Racecraft

Kenneth Warren is an English professor at The University of Chicago.

VersoBooks.com
He recommends "Racecraft: The Soul of Inequality in American Life," by Karen E. Fields and Barbara J. Fields saying, "given the resurgence of questions about race in American society I think everyone should take a look at the 2014 book."

Harold Bloom, Yale: Shakespeare

Harold Bloom, an American literary critic and Sterling Professor of Humanities at Yale, kept it short and sweet saying students should read, "all of Shakespeare."

Experts have discovered the first mutation in the development of human evolution.

Pixabay
For the first time, scientists have caught a glimpse of the earliest genetic mutations in human development.

Using whole genome sequencing, they wound back time on cell samples from adults and revealed what took place in the genome when they were still microscopic embryos. It turns out, our first two cells contribute to our development in very different ways.

Biology Reference

Mutations come in two forms: the hereditary ones we get from our parents, which can be found in virtually every cell of the body; and the acquired (or somatic) mutations that can occur at any stage of a person's life, including those very first days when the embryo is just starting to split into multiple cells.

Somatic mutations don't necessarily cause problems, but they can sometimes lead to cancer and other diseases. They also don't necessarily live in every cell (that's called mosaicism). 

We have a fairly murky understanding of the somatic mutations that happen during the earliest life stages, because we can't just watch that stuff happening in real time.

But now researchers have discovered a way to trace these mutations back to their first appearance.

Medical Xpress

"This is the first time that anyone has seen where mutations arise in the very early human development. It is like finding a needle in a haystack," says geneticist Young Seok Ju from the Wellcome Trust Sanger Institute in the UK and the Korea Advanced Institute of Science and Technology.


"There are just a handful of these mutations, compared with millions of inherited genetic variations, and finding them allowed us to track what happened during embryogenesis."

To find these mutations, the team analysed blood and tissue samples from 279 people with breast cancer. Using samples from cancer patients allowed them to test whether mutations were present in both normal blood and tissue, and in surgically removed tumour samples.

Since breast cancer tumours develop from a single cell, a somatic mutation would either be present in every tumour cell, or not at all, which gives a clue to its possible origins.

By tracking and comparing the spread of different mutations in these various tissue samples, the scientists verified a whopping 163 mutations that must have happened within the first few cell divisions of the persons' embryonic development.

University of South Florida

This gave them a unique insight into how early embryonic cells interact.

And that's not all - a statistical analysis revealed that when a fertilised egg divides for the first time, those two cells actually contribute building material for the rest of the body at different proportions.

It appears that one of the first two cells that make us up gives rise to 70 percent of the body tissue, while the other one chips in for the rest.

"We determined the relative contribution of the first embryonic cells to the adult blood cell pool and found one dominant cell - that led to 70 percent of the blood cells - and one minor cell," says molecular biologist Inigo Martincorena from the Sanger Institute.

indiatoday.intoday.in

"This opens an unprecedented window into the earliest stages of human development."

That's exciting, because having that window will let us discover even more about how humans develop and acquire various mutations from the get-go.

Even though the vast majority of mutations are random and harmless, occasionally they can affect an important gene, causing a developmental disorder or a disease.

"Essentially, the mutations are archaeological traces of embryonic development left in our adult tissues, so if we can find and interpret them, we can understand human embryology better," says lead researcher Mike Stratton, director of the Wellcome Trust Sanger Institute.

The researchers hope their discovery is just the first of many steps that will help us gain a better understanding of what happens to humans in the earliest days, when we're all nothing more than just a clump of cells.

Less than four months after Hitler's death, a great future US president declared in great secrecy love for the Führer

Wikimedia Commons 
A diary kept by President John F Kennedy as a young man travelling in Europe, revealing his fascination with Adolf Hitler, is up for auction.

Kennedy, then 28, predicted "Hitler will emerge from the hatred that surrounds him now as one of the most significant figures who ever lived".

"He had in him the stuff of which legends are made," he continued.
Kennedy wrote the entry in the summer of 1945 after touring the German dictator's Bavarian mountain retreat.
It is thought by historians to be the only diary ever kept by the 35th US president.

RR AUCTION
The original copy will be auctioned for the first time on 26 April in Boston by longtime owner Deirdre Henderson, who worked as a research assistant for Kennedy while he was a US senator with White House ambitions.

He wrote that Hitler "had boundless ambition for his country which rendered him a menace to the peace of the world, but he had a mystery about him in the way he lived and in the manner of his death that will live and grow after him".

The 61-page diary was kept by Kennedy around four months after Hitler committed suicide.


At the time, the young American was touring Europe as a newspaper reporter after finishing his military service aboard a ship in the Pacific Ocean.

GETTY IMAGES
Nearly two decades later Kennedy would address crowds in West Berlin as US president.

He gave Ms Henderson the diary in order to inform her of his views on foreign policy and national security, she said.

In a description of the auction, she wrote: "When JFK said that Hitler 'had in him the stuff of which legends are made', he was speaking to the mystery surrounding him, not the evil he demonstrated to the world."

"Nowhere in this diary, or in any of his writings, is there any indication of sympathy for Nazi crimes or cause," she continued.
The diary also contains JFK's thoughts about the British election and Winston Churchill, who Ms Henderson called his "idol".

The winning bid is expected to be around $200,000 (£160,000).

IBM is Rolling out the World's First Universal 'Quantum Computing' Service

sakkmesterke/Shutterstock.com
We're all excited about the potential of quantum computers - devices that will harness strange quantum phenomena to perform calculations far more powerful than anything conventional computers can do today.

Unfortunately, we still don't have a tangible, large-scale quantum computer to freak out over just yet, but IBM is already preparing for a future when we do, by announcing that they're rolling out a universal 'quantum-computing' service later this year.

The service will be called IBM Q, and it will give people access to their early-stage quantum computer over the internet to use as they wish - for a fee.

The big elephant in the room is that, for now, IBM's quantum computer only runs on five qubits, so it's not much faster (if any faster) than a conventional computer.

But their technology is improving all the time. The company has announced it hopes to get to 50 qubits in the next few years, and in the meantime, it's building the online systems and software so that anyone in the world can access the full power of its quantum computer when it's ready. IBM Q is a crucial part of that.

Unlike conventional computers, which use 'bits' of either 1 or 0 to code information, quantum computers use a strange phenomenon known as superposition, which allows an atom to be in both the 1 and 0 position at the same time. These quantum bits, or qubits, give quantum computers far more processing power than traditional computers.

But right now, qubits are hard to make and manipulate, even for more the most high-tech labs. Which is why IBM only has five qubits working together in a computer, despite decades of research. And those qubits have to be cooled to temperatures just above absolute zero in order to function.

Companies such as Google, and multiple university research labs, have also built primitive quantum computers, and Google has even used theirs to simulate a molecule for the first time, showing the potential of this technology as it scales up.

But instead of just focussing on the hardware itself, IBM is also interested in the software around quantum computers, and how to give the public access to them.

"IBM has invested over decades to growing the field of quantum computing and we are committed to expanding access to quantum systems and their powerful capabilities for the science and business communities," said Arvind Krishna, senior vice president of Hybrid Cloud and director for IBM Research.

The system builds on the company's Quantum Experience, which was rolled out last year for free to approved researchers. IBM Q will use similar cloud software, but will also be open to businesses - and, more importantly, any programmers and developers who want to start experimenting with writing code for quantum systems.

The goal is to have a functional, commercial, cloud-based service ready to go when a fully realised quantum computer does come online.

"Putting the machine on the cloud is an obvious thing to do," physicist Christopher Monroe from the University of Maryland, who isn't involved with IBM, told Davide Castelvecchi over at Scientific American. "But it takes a lot of work in getting a system to that level."

The challenge is that while, on paper, a five-qubit machine is pretty easy to simulate and program for, real qubits don't quite work that way, because you're working with atoms that can change their behaviour based on environmental conditions

"The real challenge is whether you can make your algorithm work on real hardware that has imperfections," Isaac Chuang, a physicist at MIT who doesn't work with IBM, told Scientific American.

In their announcement, IBM said that in the past few months, more than 40,000 users have already used Quantum Experience to build and run 275,000 test applications, and 15 research papers have been published based off of it so far.

And they predict that in future, the quantum service will become even more useful.

"Quantum computers will deliver solutions to important problems where patterns cannot be seen because the data doesn't exist and the possibilities that you need to explore to get to the answer are too enormous to ever be processed by classical computers," said IBM in its announcement.

There's no word as yet on how much IBM Q will cost to use, or how users will be approved. But we have to admit it'd be pretty cool to be among the first to play around with quantum computing.

It was discovered a huge reservoir of melted carbon deep beneath Earth's surface in the Western United States

Linda M. Foster/Shutterstock.com

Scientists have used the world's largest array of seismic sensors to map what lies deep beneath Earth's surface, and have discovered an unidentified reservoir of melting carbon under the United States, covering an area of 1.8 million square km (695,000 square miles).

The find, which is located roughly 350 km (217 miles) beneath the Western US, challenges what researchers have assumed about how much carbon is trapped inside the planet. Turns out, there's far more than anyone had predicted.

The reservoir is far too deep for the researchers to physically get to, but a team from the University of Royal Holloway London used a vast network of 583 seismic sensors that pick up on strange vibrations generated in Earth's upper mantle to identify it.

The upper mantle is the layer that sits directly under our planet's crust, and extends to a depth of about 410 km (250 miles). 

Within this layer, temperatures can span from 500 to 900°C (932 to 1,652°F) near the crust, and can reach a hellish 4,000°C (7,230°F) in the lower mantle closer to the central core.

That ridiculous heat is constantly melting carbonates - a large group of minerals such as magnesite and calcite that all contain a specific carbonate ion - and this molten carbon is thought to be responsible for the conductivity of the mantle.

The melting process also produces a unique signature of seismic patterns, which can be read by sensors on the surface by converting ground motion into an electronic signal. 

Based on what these sensors have told us, researchers now suspect that Earth's upper mantle could contain up to 100 trillion metric tonnes of melted carbon - far more than expected.

The team now thinks that the massive carbon reservoir they've identified could have formed when one of the tectonic plates that make up the Pacific Ocean was forced under the western part of the US, and has provided more fuel for the upper mantle fire.

"It would be impossible for us to drill far enough down to physically 'see' Earth's mantle, so using this massive group of sensors we have to paint a picture of it using mathematical equations to interpret what is beneath us," says one of the team, Sash Hier-Majumder.

"Under the western US is a huge underground partially-molten reservoir of liquid carbonate. It is a result of one of the tectonic plates of the Pacific Ocean forced underneath the western US, undergoing partial melting, thanks to gasses like CO2 and H2O contained in the minerals dissolved in it."

While none of that will affect us much today - it's 350 km deep, after all - one day, it will, and in the most dramatic fashion.

As Hier-Majumder explains, it's expected that the contents of the melted carbon reservoir will slowly make their way up to the surface via volcanic eruptions. 

These eruptions are how carbon from inside our planet makes its way into the atmosphere - something that wouldn't usually be a problem, if we weren't already emitting roughly 40 billion tonnes of the stuff every year.

"We might not think of the deep structure of Earth as linked to climate change above us, but this discovery not only has implications for subterranean mapping, but also for our future atmosphere," says Hier-Majumder. 

"Releasing only 1 percent of this CO2 into the atmosphere will be the equivalent of burning 2.3 trillion barrels of oil. The existence of such deep reservoirs show how important is the role of deep Earth in the global carbon cycle."

Another step into the future: A new kind of magnet recently discovered, Will revolutionize today's technology

Scientists have discovered the magnetism of electrons in three layers of graphene. This study reveals a new kind of magnet and provides insight on how electronic devices using graphene could be made for fundamental studies as well as various applications.

Metals have a large density of electrons and to be able to see the wave nature of electrons one has to make metallic wires that are only a few atoms wide. However, in graphene -- one atom thick graphite -- the density of electrons is much smaller and can be changed by making a transistor. As a result of the low density of electrons the wave nature of electrons, as described by quantum mechanics, is easier to observe in graphene.

Often in metals like copper the electron is scattered every 100 nanometers, a distance roughly 1000 times smaller than the diameter of human hair, due to impurities and imperfections. Electrons can travel much longer in graphene, up to distances of 10 micrometer, a distance roughly 10 times smaller than the diameter of human hair. This is realized by sandwiching graphene between layers of boron nitride. The layers of boron nitride have few imperfections to impede the flow of electrons in graphene.

Once electrons travel long distances, implying there are few imperfections, one notices the faint whispers of electrons "talking to each other." Reducing the imperfections is akin to making a room quiet to enable the faint whispers of electronic interactions to develop between many electrons.

In a study, led by PhD student Biswajit Datta, Professor Mandar Deshmukh's group at TIFR realized just this kind of silence allowing electronic interactions to be observed in three layers of graphene. The study reveals a new kind of magnet and provides insight on how electronic devices using graphene could be made for fundamental studies as well as applications. This work discovers the magnetism of electrons in three layers of graphene at a low temperature of -272 Celsius. The magnetism of electrons arises from the coordinated "whispers" between many electrons.
