This Watch Accurately Tracks Moon Phases For 122 Years
Terrible Advice From a Great Scientist
In your analogy, you're talking about a very high-level split that can be done cleanly. One person does the creative work of coming up with a game design (storyline, play control, etc.) without worrying about the underlying implementation details. Then another person can certainly do the engineering and coding work to implement that.
But it should be obvious that for some other problems this won't work. For example, it doesn't make sense to try and split the coding into a "creative coder" (who knows nothing about programming) and an "implementation coder" who turns the creative's ideas into actual code. The creative would toss out nonsensical ideas (like "instead of using vectors, why not use genetic algorithms?"), and then the implementer would have to explain why all those ideas are silly... or else they would just have to ignore the creative type and simply code something that makes sense.
In other words, generating good source code requires someone who knows enough about programming that they can see creative solutions. Their intuition is not separate from their programming talent: their intuition is based upon years of training and experience with source code, math, engineering, and so forth. That's where the good ideas come from.
Coming up with good scientific ideas is similar. Analysing scientific data even moreso. It's only once you have a deep, subliminal understanding of the important concepts that you're going to make substantive progress. Whether a deep understanding of math counts as an "important concept" depends on the field, of course... but I would argue that for science generally, the more mathematical know-how you have, the more informed and powerful your ideas will be.

Neil Patrick Harris And David Burtka Reportedly Leaving Their Gorgeous California Home For New York City (VIDEO, PHOTOS)
It looks like Neil Patrick Harris and partner David Burtka are planning a big move.
According to Us Magazine, the couple intend to leave Los Angeles and head to New York City after Harris shoots the final season of How I Met Your Mother.
This news has us wondering if they'll ever be able to find a place like the one they have now. Back in 2012 we got to see a house tour when the two were on Oprah's Next Chapter. The couple showed off their amazing California home complete with contemporary art, a cozy living room and stunning kitchen space.
We also got to see Harris' "Magic Man Cave," which is hidden behind a door that looks like a poster. The red walls, black leather furniture and trinkets do have a, err, magical feeling. "I used to have magic everywhere," Harris told Oprah. "And David got mad at me, so he forced all of my magic in one room."
To try and find a new place with a magic room might take a while -- as if house hunting in New York City isn't hard enough.
Watch the video above to see more of Patrick and David's California home. And be sure to head over to Us Magazine for more information.

Fundamentalism and the Chechens' fighting history
The ancestral home of the Boston Marathon bombing suspects, Tamerlan and Dzhokhar Tsarnaev, has long been a land of fighters, but it took on the character of an Islamic jihad in the 1990s.
Chechen fighters celebrate the withdrawal of Russian troops from their republic in August 1996.

Already, it was home to a warrior culture, down to the very bone.
Throughout the mountain towns of the Caucasus, gymnasiums were full of wiry teens and young men learning to box, wrestle, and practice Asian martial arts. Speed bags hung from trees the way basketball hoops decorate American driveways.
Caucasians were heavily overrepresented in the combat sports on Russian, and before that Soviet, national teams.??It?s not surprising that Tamerlan Tsarnaev was a boxer and the younger Dzhokhar a wrestler.
For at least two centuries, Chechens and their neighbors have been fighting to throw off the yoke of Russian domination. When the Soviet Union collapsed in 1991, that fight heated up again.
Chechnya was pummeled brutally in the process. The main city of Grozny was largely reduced to rubble. People hand carried their water in buckets even to high-rise apartments. Few windows were left unshattered. Gas flares from ruptured pipes created huge torches on block after block. Garbage piled up on empty or pulverized lots and cows grazed through it. In the buildings where families still lived, they spray painted ?zhivoot? ? living ? on the outside walls, hoping to dissuade Russian soldiers from blowing it up.
But through all that the Chechens radiated toughness. The young men kept to the mountains, coming down to buy rifles from demoralized and poorly paid Russian soldiers ? and then to attack them with their own guns.
But by the time the Russians agreed to withdraw their troops from Chechnya in 1996, a change was visible in Chechen attitudes. The region had been Muslim for centuries, but Islam was moving more to the center of the Chechen fight. A few Arabs ? some of them veterans of the war against Soviets in Afghanistan ? came to set up madrasas to teach a fundamentalist, Wahhabi version of Islam. It made some rapid inroads, dividing mountain villages with sometimes murderous results.
When the Russians withdrew their tanks from Chechnya, long lines of them rumbling out of the mountains, men who appeared to be Arabs, with long beards, black flags with Arabic characters, and Korans held open for all to see, rode on the gun turrets.
The nationalistic flavor of the Chechen war seemed to be taking on the character of an Islamic jihad.
In the years since, Chechens have once again been suppressed by the heavy hand of Russia and in retaliation, Chechens have claimed credit for a series of horrific acts of terror against Russians ? including the massacre of schoolchildren at Beslan, the taking of an entire Moscow theater audience hostage, and a series of apartment building and subway station bombings with scores of fatalities.
From the days of Catherine the Great to the early 1990s, Russian soldiers showed a grudging respect for the great warriors of the Caucasus who fought, soldier to soldier, for their independence.
One can only imagine what the legendary Shamil ? a Caucasian hero of the 19th century ? would think of the last decade of attacks on children and other noncombatants.

Babies are conscious? Science confirms what moms know.
Babies are aware of what's going on, not just reflexively reacting to it, scientists concluded after a series of experiments on babies as young as 5 months.
A contestant in the 2000 American Baby Derby heads towards the finish line. Crawling babies raced to see who was fastest. According to the promoters, The Boston Baby Faire, a two-day event with more than 200 exhibitors of every type of baby product, is the largest baby exposition in the United States.

New parents may raise an eyebrow at the idea that their baby might not be a conscious being, but scientists have, until now, not been able to clearly show that infants react with awareness rather than reflexively. Even in adults, much of the brain's processing of the world occurs without conscious awareness, said Sid Kouider, a neuroscientist at the Laboratoire de Sciences Cognitives et Psycholinguistique in Paris and the Technical University of Denmark. ?
One odd phenomenon, "blindsight," occurs in people with damage to part of their visual cortex. Although they cannot consciously see, they're able to "guess" the location of a visual stimulus or even catch objects tossed at them. Blindsight reveals that even unconscious processing in the brain can result in seemingly goal-directed behavior.
So when babies look toward a face or grasp an object, they, too, might be doing so without a conscious experience of what they're seeing.
"Infants might be responding in a kind of automatic manner," Kouider told LiveScience. Unfortunately, since babies don't talk, scientists can't test consciousness by asking infants what they experience.
Baby brain patterns
So Kouider and his colleagues turned to brain activity for a peak into babies' awareness. When adults are shown a subliminal image, their brains show a spike in electrical activity in sensory regions ? even though they may not consciously register that they've seen such a brief image.
When the image does consciously register, however, the brain shows a second leap in activity, typically about 300 milliseconds after the presentation of the image. This pattern reveals visual consciousness, Kouider said, which means that not only does the brain respond to the image, but also the owner of that brain perceives that response and has a conscious experience of the image.
The researchers wanted to know whether babies would show this same brain pattern. They recruited 30 5-month-olds, 29 12-month-olds and 21 15-month-olds and fitted the babies with electrode caps that measure the brain's electrical activity through the scalp.
Next, the babies sat on their mother or father's lap while watching a screen with a patterned image. For a fraction of a second (ranging from as quick as 17 milliseconds up to 300 milliseconds), the researchers flashed a photo of a face on the screen.
Experiencing awareness
The scientists then analyzed the babies' brain activity to search for the two-phase pattern that would indicate consciousness. They found it: Babies did indeed show a secondary spike in neural activity, just like adults.
But there was one important difference between the babies' neural patterns and those seen in adults, Kouider said. In 5-month-olds, it took 1.3 seconds for the second flurry of brain activity to show up. In adults, the timing is closer to three-tenths of a second, or 0.3 seconds.
"It's about four times slower, actually, in the younger infants," Kouider said.?
Older babies show snappier processing, though still not as quick as adults, the researchers found. In 12- to 15-month-olds, the second phase is stronger than in 5-month-olds and occurs around eight-tenths to nine-tenths of a second.

Is Sinai Israel?s Achilles? heel?
The al-Qaida-affiliated terrorists who targeted Eilat with rockets on Wednesday morning believe they have found Israel?s strategic Achilles? heel.
Striking from Egypt?s Sinai Peninsula, they hope, rules out Israeli retaliation. Jerusalem is highly reluctant to embark on any kind of counterterrorism operation on Egyptian territory, a fact readily exploited by Wednesday?s attackers. (Jerusalem Post, Posted 19 Apr 13)

Officer fatally shot on MIT campus
WATERTOWN, Mass. (AP) ? One of two suspects in the Boston Marathon bombing is dead and a massive manhunt is underway for another, authorities said early Friday.
Residents of Watertown, a Boston suburb, have been advised to keep their doors locked and not let anyone in.
The Middlesex district attorney said the two men are suspected of killing a Massachusetts Institute of Technology police officer on campus late Thursday, then stealing a car at gunpoint and later releasing its driver unharmed. Hours earlier, police had released photos of the marathon bombing suspects and asked for the public's help finding them.
Authorities say the suspects threw explosives from the car as police followed it into Watertown. The suspects and police exchanged gunfire, and one of the suspects was critically injured and later died while the other escaped.
"We believe this to be a terrorist," Boston police Commissioner Ed Davis said. "We believe this to be a man who came here to kill people."
The FBI said it is working with local authorities to determine what happened.
The MIT shooting on the Cambridge campus Thursday night was followed by reports of gunfire and explosions in Watertown, about 10 miles west of Boston.
The MIT officer had been responding to report of a disturbance Thursday night when he was shot multiple times, according to a statement from the Middlesex district attorney's office and Cambridge police. It said there were no other victims.
In Watertown, witnesses reported hearing multiple gunshots and explosions at about 1 a.m. Friday. Dozens of police officers and FBI agents were in the neighborhood and a helicopter circled overhead.
State police spokesman David Procopio said, "The incident in Watertown did involve what we believe to be explosive devices possibly, potentially, being used against the police officers."
Boston cab driver Imran Saif said he was standing on a street corner at a police barricade across from a diner when he heard an explosion.
"I heard a loud boom and then a rapid succession of pop, pop, pop," he said. "It sounded like automatic weapons. And then I heard the second explosion."
He said he could smell something burning and advanced to check it out but area residents at their windows yelled at him, "Hey, it's gunfire! Don't go that way!"
MIT said right after the 10:30 p.m. shooting that police were sweeping the campus in Cambridge and urged people to remain indoors. They urged people urged to stay away from the Stata Building, a mixed-use building with faculty offices, classrooms and a common area.
Hours later, MIT, which has about 11,000 students, said the campus was clear but the shooter was still on the loose.
