Empathy vs. Sympathy

empathy_sympathyThe terms and empathy and sympathy are often confused, and with good reason. Both of the words deal with the relationship one has to the feelings and experiences of another. Today we explore the differences between these terms and how they are most commonly used.
Both sympathy and empathy have roots in the Greek term páthos meaning “suffering, feeling.” The prefix sym- comes from the Greek sýn meaning “with, together with” and the prefix em- derives from the Greek en- meaning “within, in.”
Sympathy is the older of the two terms. It entered English in the mid-1500s with a very broad meaning of “agreement or harmony in qualities between things or people.” Since then, the term has come to be used in a more specific way. Nowadays sympathy is largely used to convey commiseration, pity, or feelings of sorrow for someone who is experiencing misfortune. This prevailing sense is epitomized in the category of greeting card most often labeled “sympathy” that specializes in messages of support and sorrow for those in a time of need.
Consider the following examples:
“There was little sympathy in England for David Beckham … when he received a red card in a 1998 World Cup loss to Argentina.” –New York Times,  July 2, 2015
“…the new [Facebook] feature would automatically replace the existing ‘like’ button with a ‘sympathize’ one when users tag their statuses with a negative emotion, like ‘sad’ or ‘depressed.’” –New York, December 6, 2013
Empathy entered English a few centuries after sympathy—in the late 1800s—with a somewhat technical and now obsolete meaning from the field of psychology, which referred to the physiological manifestation of feelings. Unlike sympathy, empathy has come to be used in a more broad way than it was when it was first introduced into the lexicon; the term is now most often used to refer to the capacity or ability to imagine oneself in the situation of another, thereby vicariously experiencing the emotions, ideas, or opinions of that person.
Consider the following examples:
“…many of us believe that if more lives are at stake, we will — and should — feel more empathy (i.e., vicariously share others’ experiences) and do more to help.” –New York Times, July 10, 2015
“I think that’s almost what it is sometimes if you sum up what acting is. It’s just the ultimate expression of empathy.” –Emily Blunt, Los Angeles Times, December 8, 2014
To sum up the differences between the most commonly used meanings of these two terms: sympathy is feeling compassion, sorrow, or pity for the hardships that another person encounters, while empathy is putting yourself in the shoes of another.

RED SEA : Archaeologists Discover Remains Of Egyptian Army From Biblical Exodus





Suez| Egypt’s Antiquities Ministry announced this morning that a team of underwater archaeologists had discovered that remains of a large Egyptian army from the 14th century BC, at the bottom of the Gulf of Suez, 1.5 kilometers offshore from the modern city of Ras Gharib.
The team was searching for the remains of ancient ships and artifacts related to Stone Age and Bronze Age trade in the Red Sea area, when they stumbled upon a gigantic mass of human bones darkened by age.
The scientists lead by Professor Abdel Muhammad Gader and associated with Cairo University’s Faculty of Archaeology, have already recovered a total of more than 400 different skeletons, as well as hundreds of weapons and pieces of armor, also the remains of two war chariots, scattered over an area of approximately 200 square meters.
They estimate that more than 5000 other bodies could be dispersed over a wider area, suggesting that an army of large size who have perished on the site.

This magnificient blade from an egyptian khopesh, was certainly the weapon of an important character. It was discovered near the remains of a richly decorated war chariot, suggesting it could have belonged to a prince or nobleman.
khopesh
Many clues on the site have brought Professor Gader and his team to conclude that the bodies could be linked to the famous episode of the Exodus. First of all, the ancient soldiers seem to have died on dry ground, since no traces of boats or ships have been found in the area.
The positions of the bodies and the fact that they were stuck in a vast quantity of clay and rock, implie that they could have died in a mudslide or a tidal wave. The shear number of bodies suggests that a large ancient army perished on the site and the dramatic way by which they were killed, both seem to corroborate the biblical version of the Red Sea Crossing, when the army of the Egyptian Pharaoh was destroyed by the returning waters that Moses had parted.
This new find certainly proves that there was indeed an Egyptian army of large size that was destroyed by the waters of the Red Sea during the reign of King Akhenaten. For centuries, the famous biblical account of the “Red Sea Crossing” was dismissed by most scholars and historians as more symbolic than historical.
This astounding discovery brings undeniable scientific proof that one the most famous episodes of the Old Testament was indeed, based on an historical event. It brings a brand new perspective on a story that many historians have been considering for years as a work of fiction, and suggesting that other themes like the “Plagues of Egypt” could indeed have an historical base.
A lot more research and many more recovery operations are to be expected on the site over the next few years, as Professor Gader and his team have already announced their desire to retrieve the rest of the bodies and artifacts from was has turned out to be one of the richest archaeological underwater sites ever discovered ( via worldnewsdailyreport.com ).” copied.  Disclose TV

Foreign teachers leave Tanzania

The decision by the Tanzanian government to kick out illegal immigrants had led to the expulsion of more than 5,500 foreign teachers as at the end of January.
The teachers, mostly from the region, went back to their countries after the Immigration Department issued a notice to private school owners requiring them to submit work permits of their foreign teaching staff.
The decision to expel workers without valid work permits was made after immigration authorities and the police apprehended foreigners from the Horn of Africa a few months ago.
A senior immigration officer in Dar es Salaam said there were hundreds of illegal foreigners working in Tanzania’s business capital, most of them from Kenya, China, India, Pakistan and Malawi.
“We are tracking them down to verify their presence in Tanzania before taking legal action against them,” he said.
English and science teachers from Kenya and other EAC member states were the most affected. There are more than 6,000 foreigners hired by private schools in Tanzania.
Mzinde Mnzava, the chairman of the Tanzania Association of Managers and Owners of Non-Government Schools and Colleges (TAMONGSCO), said the country has a shortage of 27,000 science teachers.
“We request the government to relax the working regulations for foreign teachers to allow us to hire more teachers who are experienced to fill this gap,” he said.
Private schools perform better than public schools in the country.
TAMONGSCO secretary general Benjamin Nkonya said deporting foreign teachers will affect private schools, many of which hire English teachers from Kenya and Uganda.
“The decision made by the government will have a major negative impact on private English-medium schools since many Tanzanian teachers are not competent in English and science studies,” he said.
He said colleges in Tanzania did not train enough primary school teachers in English; most are trained in history and geography.
Tanzania Teachers Union president Gratian Mukoba said the union is not against the government’s move to crack down on foreign and illegal immigrants, but added, “If we want to have children who are well educated, there is a need to have foreigners who will help us to train the future generation,” he said.
East African Employers Association chair Rosemary Ssenabulya faulted Tanzania’s move to “lock out” other East Africans from their job market.
She said the move was against the EAC Common Market Protocol that advocates for free movement of labour across the borders of member states.

Sunday, February 14, 2016 Besigye has won moral victory before a vote is cast in Uganda

On a cloudy Kampala day last Wednesday, I witnessed an exceedingly rare development.
The opposition candidate in Uganda’s election was campaigning in the Makindye neighbourhood of the capital and, when he arrived, people surged forward.
They didn’t want to shake his hands. They were giving him money. Tens of them had a donation to make to Dr Kizza Besigye.
An old lady, clad in a long blue lesso, thrust a crumpled note in his hands. Several young men followed and gave the leader some money.
Others brought gifts: pawpaws, pineapples and, of course, this being Uganda, bananas.
It is a scene which has unfolded across the country everywhere the candidate has gone and one can hardly think of a more eloquent message to an incumbent than the one these peasants have sent by giving up their money to support Besigye.
The statement seems to be that Yoweri Museveni may have all the state resources, the men with guns may be on his side, but the people feel that 30 years is a little too long for one man to cling to power and they are eager for change.
So from Mbale to Gulu, people have come forward to give Besigye a donation. Some have offered goats, others gave him cows. One cheeky guy brought him a German Shepherd puppy, the better for him to catch “corrupt thieves” with.
Besigye will probably not win when Ugandans go to the polls on Thursday. The opposition in Uganda relies too much on the charisma of one man and lacks a credible national grassroots network.
It is not fielding candidates in a fair proportion of parliamentary contests.
Museveni’s NRM has all the money and is outspending the opposition almost totally.
GRASSROOTS NETWORK
Besigye’s FDC does not quite have the level of grassroots network and financing that its counterparts in, say, Ghana or Kenya command, partly because in Ghana and Kenya, major opposition figures have served in government in the recent past and therefore generally have fairly deep pockets.
The electoral landscape is additionally tilted in Museveni’s favour by the overwhelming role of state institutions in campaigning for him, especially in rural areas, and the ruling party’s propaganda that a loss for Museveni will result in war.
People have absorbed all that and there is general fatalism that the incumbent will remain in office.
But Museveni, once one of the continent’s foremost idealists, and a man who engineered a genuine turnaround and made Uganda a respectable country after years of war, has totally betrayed his ideals and now joins the ranks of many other personal rulers around the world. As a friend put it to me, how can a man go to the same office for 30 years and not grow tired of it?
Why don’t these fellows realise that they can enjoy a good life out of power and, with Museveni’s gift for (occasionally) amusing long lectures, he can be a celebrity on the retired presidential lecture circuit?
A country yoked to the same leader for decades loses its edge in terms of dynamism and growth as Kenya showed in 2002.
We will see who will win the election on Thursday. But the peasants of Uganda, in donating their hard-earned money to Besigye, in giving him the produce of their farms to fund his campaign for president, have delivered a ringing verdict on their view of Museveni’s quest to be president for life.
TAUGHT A VALUABLE LESSON
They have also taught a valuable lesson to other Africans. It makes little sense to expect politicians to buy votes with stolen money at election time then hope they won’t be corrupt once in office.
However, donating money to a candidate who is genuinely clean and desires real change offers a powerful incentive for them to stay clean.
The Besigye supporters have handed the FDC chief a moral victory and given other Africans food for thought.
***
As usual, I played the well known foreign correspondents’ game of asking taxi drivers who they think will win the election.
Due to Kampala’s traffic jams you have to use boda boda constantly to get anywhere and all the taxi and boda boda guys I spoke to want Besigye to win (which does not mean he will as I learnt in Dar es Salaam. Views in the capital often differ from what you might hear in the countryside).
Maybe the best answer came from one rider, Muhwezi, who replied thus to the question of what the outcome of the election might be.
“Aaaah!” he said. “Only God knows.”

Thursday, February 11, 2016 Regulator wades into KQ, Fastject price war

The airline regulator has dived into the price war between Fastjet and Kenya Airways demanding that the former sets its prices inclusive of all taxes involved.
Budget carrier Fastjet has prices exempting tax, luggage charges and other levies. The prices appear low luring consumers as KQ struggles to keep up by cutting its prices by 30 per cent. The Kenya Civil Aviation Authority has now ordered Fastjet to include ‘taxes, fees and other charges’ on its pricing, stating that the law requires that passengers are accurately informed.
“It has come to the notice of the authority that airlines continue to advertise in the local print media prices that are exclusive of taxes, fees and other charges,” said the director general KCAA Gilbert Kibe in a notice in the dailies.
Fastjet and Kenya Airways are at the peak of prolonged price wars that have forced the latter to lower its charges for the Dar-Nairobi route with the hope of retaining customers along the way.
However, the majority of fliers have fallen prey to Fastjet’s ‘low’ prices whose offers are Sh5,500 for a one way trip and Sh8,000 for the Kilimanjaro-Nairobi. KQ’s lowest prices on one way for the same route are around Sh32,000 inclusive of taxes.
Fastjet East Africa General Manager Jimmy Kibati says the airline targets first time flyers. “The travelling public pays prohibitively high fares for regional air travel.”
“The consumer protection Act 2012 is also clear on this matter. Any further advertising without adhering to the above provisions shall be dealt with according to existing legislation,” the KCAA states.

A Quixotic Project

Dr. Thorne of Caltech and Dr. Weiss of M.I.T. first met in 1975, Dr. Weiss said, when they had to share a hotel room during a meeting in Washington. Dr. Thorne was already a renowned black-hole theorist, but he was looking for new experimental territory to conquer. They stayed up all night talking about how to test general relativity and debating how best to search for gravitational waves.
Dr. Thorne then recruited Dr. Drever, a gifted experimentalist from the University of Glasgow, to start a gravitational wave program at Caltech. Dr. Drever wanted to use light — laser beams bouncing between precisely positioned mirrors — to detect the squeeze and stretch of a passing wave.
Dr. Weiss tried to mount a similar effort at M.I.T., also using the laser approach, but at the time, black holes were not in fashion there. (Things are better now, he said.)

The technological odds were against both efforts. The researchers calculated that a typical gravitational wave from out in space would change the distance between a pair of mirrors by an almost imperceptible amount: one part in a billion trillion. Dr. Weiss recalled that when he explained the experiment to his potential funders at the National Science Foundation, “everybody thought we were out of our minds.”
In 1984, to the annoyance of Dr. Drever and the relief of Dr. Weiss, the National Science Foundation ordered the two teams to merge. Dr. Thorne found himself in the dual roles of evangelist for the field of gravitational waves and broker for experimental disagreements.
Progress was slow until the three physicists were replaced in 1987 by a single director as part of the price of going forward.
The first version of the experiment, known as Initial LIGO, started in 2000 and ran for 10 years, mostly to show that it could work on the scale needed. There are two detectors: one in Hanford, Wash., the other in Livingston, La. Hunters once shot up the outside of one of the antenna arms in Louisiana, and a truck crashed into one of the arms in Hanford. In neither case was the experiment damaged.
Over the last five years, the entire system was rebuilt to increase its sensitivity to the point where the team could realistically expect to hear something.
LIGO’s antennas are L-shaped, with perpendicular arms 2.5 miles long. Inside each arm, cocooned in layers of steel and concrete, runs the world’s largest bottle of nothing, a vacuum chamber a couple of feet wide containing 2.5 million gallons of empty space. At the end of each arm are mirrors hanging by glass threads, isolated from the bumps and shrieks of the environment better than any Rolls-Royce ever conceived.
Thus coddled, the lasers in the present incarnation, known as Advanced LIGO, can detect changes in the length of one of those arms as small as one ten-thousandth the diameter of a proton — a subatomic particle too small to be seen by even the most powerful microscopes — as a gravitational wave sweeps through.

An Earthling’s Guide to Black Holes

Welcome to the place of no return — a region in space where the gravitational pull is so strong that not even light can escape it. This is a black hole.
Even with such extreme sensitivity, only the most massive and violent events out there would be loud enough to make the detectors ring. LIGO was designed to catch collisions of neutron stars, which can produce the violent flashes known as gamma ray bursts.
As they got closer together, these neutron stars would swing around faster and faster, hundreds of times a second, vibrating space-time geometry with a rising tone that would be audible in LIGO’s vacuum-tube “sweet spot.”
Black holes, the even-more-extreme remains of dead stars, could be expected to do the same, but nobody knew if they existed in pairs or how often they might collide. If they did, however, the waves from the collision would be far louder and lower pitched than those from neutron stars.
Dr. Thorne and others long thought these would be the first waves to be heard by LIGO. But even he did not expect it would happen so quickly.

‘It Was Waving Hello’

On Sept. 14, the system had barely finished being calibrated and was in what is called an engineering run at 4 a.m. when a loud signal came through at the Livingston site. “Data was streaming, and then ‘bam,’ ” recalled David Reitze, a Caltech professor who is the director of the LIGO Laboratory, the group that built and runs the detectors.
Seven milliseconds later, the signal hit the Hanford site. LIGO scientists later determined that the likelihood of such signals landing simultaneously by pure chance was vanishingly small. Nobody was awake, but computers tagged the event.

What Is General Relativity?

Einstein presented his general theory of relativity 100 years ago this month.

Dr. Reitze was on a plane to Louisiana the next day. Dr. Weiss, on vacation in Maine, found out when he checked in by computer that morning. “It was waving hello,” he said. “It was amazing. The signal was so big, I didn’t believe it.”
The frequency of the chirp was too low for neutron stars, the physicists knew. Detailed analysis of its form told a tale of Brobdingnagian activities in a far corner of the universe: the last waltz of a pair of black holes shockingly larger than astrophysicists had been expecting.
One of them was 36 times as massive as the sun, the other 29. As they approached the end, at half the speed of light, they were circling each other 250 times a second.
And then the ringing stopped as the two holes coalesced into a single black hole, a trapdoor in space with the equivalent mass of 62 suns. All in a fifth of a second, Earth time.
Dr. Weiss said you could reproduce the chirp by running your fingernails across the keys of a piano from the low end to middle C.
Lost in the transformation was three solar masses’ worth of energy, vaporized into gravitational waves in an unseen and barely felt apocalypse. As visible light, that energy would be equivalent to a billion trillion suns.
And yet it moved the LIGO mirrors only four one-thousandths of the diameter of a proton.

Scientists Detect Gravitational Waves, Proving Einstein Right

De
A team of physicists who can now count themselves as astronomers announced on Thursday that they had heard and recorded the sound of two black holes colliding a billion light-years away, a fleeting chirp that fulfilled the last prophecy of Einstein’s general theory of relativity.
That faint rising tone, physicists say, is the first direct evidence of gravitational waves, the ripples in the fabric of space-time that Einstein predicted a century ago. And it is a ringing (pun intended) confirmation of the nature of black holes, the bottomless gravitational pits from which not even light can escape, which were the most foreboding (and unwelcome) part of his theory.
More generally, it means that scientists have finally tapped into the deepest register of physical reality, where the weirdest and wildest implications of Einstein’s universe become manifest.
Conveyed by these gravitational waves, an energy 50 times greater than that of all the stars in the universe put together vibrated a pair of L-shaped antennas in Washington State and Louisiana known as LIGO on Sept. 14.

If replicated by future experiments, that simple chirp, which rose to the note of middle C before abruptly stopping, seems destined to take its place among the great sound bites of science, ranking with Alexander Graham Bell’s “Mr. Watson — come here” and Sputnik’s first beeps from orbit.
“We are all over the moon and back,” said Gabriela González of Louisiana State University, a spokeswoman for the LIGO Scientific Collaboration, short for Laser Interferometer Gravitational-Wave Observatory. “Einstein would be very happy, I think.”
Members of the LIGO group, a worldwide team of scientists, along with scientists from a European team known as the Virgo Collaboration, published a report in Physical Review Letters on Thursday with more than 1,000 authors.
“I think this will be one of the major breakthroughs in physics for a long time,” said Szabolcs Marka, a Columbia University professor who is one of the LIGO scientists.
“Everything else in astronomy is like the eye,” he said, referring to the panoply of telescopes that have given stargazers access to more and more of the electromagnetic spectrum and the ability to peer deeper and deeper into space and time. “Finally, astronomy grew ears. We never had ears before.”

Long-Awaited Triumph

The discovery is a great triumph for three physicists — Kip Thorne of the California Institute of Technology, Rainer Weiss of the Massachusetts Institute of Technology and Ronald Drever, formerly of Caltech and now retired in Scotland — who bet their careers on the dream of measuring the most ineffable of Einstein’s notions.

“Until now, we scientists have only seen warped space-time when it’s calm,” Dr. Thorne said in an email. “It’s as though we had only seen the ocean’s surface on a calm day but had never seen it roiled in a storm, with crashing waves.”
The black holes that LIGO observed created a storm “in which the flow of time speeded, then slowed, then speeded,” he said. “A storm with space bending this way, then that.”
The chirp is also sweet vindication for the National Science Foundation, which spent about $1.1 billion over more than 40 years to build a new hotline to nature, facing down criticism that sources of gravitational waves were not plentiful or loud enough to justify the cost.
“It’s been decades, through a lot of different technological innovations,” France Córdova, the foundation’s director, said in an interview, recalling how, in the early years, the foundation’s advisory board had “really scratched their heads on this one.”
Word of LIGO’s success was met by hosannas in the scientific community, albeit with the requisite admonishments of the need for confirmation or replication.
“I was freaking out,” said Janna Levin, a theorist at Barnard College at Columbia who was not part of LIGO but was granted an early look at the results for her warts-and-all book about the project, “Black Hole Blues,” to be published this spring.
Robert Garisto, the editor of Physical Review Letters, said he had gotten goose bumps while reading the LIGO paper.

Elusive Disturbances

When Einstein announced his theory in 1915, he rewrote the rules for space and time that had prevailed for more than 200 years, since the time of Newton, stipulating a static and fixed framework for the universe. Instead, Einstein said, matter and energy distort the geometry of the universe in the way a heavy sleeper causes a mattress to sag, producing the effect we call gravity.
A disturbance in the cosmos could cause space-time to stretch, collapse and even jiggle, like a mattress shaking when that sleeper rolls over, producing ripples of gravity: gravitational waves.
Einstein was not quite sure about these waves. In 1916, he told Karl Schwarzschild, the discoverer of black holes, that gravitational waves did not exist, then said they did. In 1936, he and his assistant Nathan Rosen set out to publish a paper debunking the idea before doing the same flip-flop again.
According to the equations physicists have settled on, gravitational waves would compress space in one direction and stretch it in another as they traveled outward.
In 1969, Joseph Weber, a physicist at the University of Maryland, made headlines when he claimed to have detected gravitational waves using a six-foot-long aluminum cylinder as an antenna. Waves of the right frequency would make the cylinder ring like a tuning fork, he said.
Others could not duplicate his result, but few doubted that gravitational waves were real. Dr. Weber’s experiment inspired a generation of scientists to look harder for Einsteinian marks on the universe.

In 1978, the radio astronomers Joseph H. Taylor Jr. and Russell A. Hulse, then at the University of Massachusetts Amherst, discovered a pair of neutron stars, superdense remnants of dead stars, orbiting each other. One of them was a pulsar, emitting a periodic beam of electromagnetic radiation. By timing its pulses, the astronomers determined that the stars were losing energy and falling closer together at precisely the rate that would be expected if they were radiating gravitational waves.
Dr. Hulse and Dr. Taylor won the Nobel Prize in Physics in 1993.
Another group of astronomers who go by the name Bicep made headlines in 2014 when they claimed to have detected gravitational waves from the beginning of the Big Bang, using a telescope at the South Pole. They later acknowledged that their observations had probably been contaminated by interstellar stardust.
