Renamed astrophysics major revamps curriculum

This semester, changes are afoot in the astronomy department.

In response to student feedback, the department made several changes that will go into effect this year, including changing the name of the Bachelor of Science degree from Astronomy and Physics to Astrophysics. The Bachelor of Arts degree will keep its name of Astronomy. The department has refocused the B.S. major on the core science skills necessary for a career in science, adding new courses like Astrostatistics and Data Mining (ASTR 356), which focuses on statistical analysis. Faculty have also made it a priority to do field work in observatories. Astronomy director of undergraduate studies Debra Fischer also reviewed all of the majors courses, revising the curriculum to eliminate overlap between courses and ensure that the curriculum is in sequential order. According to faculty members interviewed, these changes are geared at better preparing students for careers in science.

I think the redesigned curriculum prepares the students better for anything they want to do, Fischer wrote in an email. They will hit the ground running if they decide to go to grad school.

Victoria Misenti, assistant astronomy DUS, said that the majors former name, Astronomy and Physics, was sometimes mistakenly thought to be a double major. Other professors also said that the majors new name is much stronger.

[Students] didnt feel that the name was clear enough for them to be able to successfully go into graduate programs or professional careers as astronomers, Misenti said. Astrophysics was much stronger it meant something more to these graduate programs.

While Fischer said she is not sure the name change is significant, astronomy professor Louise Edwards said she hopes it will prove important. Edwards added that she hopes the majors new name will help employers recognize that Yales program develops strong analytical skills in its students.

Students are pleased with the changes, Misenti said, adding that while only the Class of 2017 and below need to meet the new set of requirements, most upperclassmen want to anyway. She also noted that the increasing number of majors suggests students are pleased with the changes.

Astronomy and physics major Hannah Alpert 15, who participated in a focus group her sophomore year to discuss possible changes for the major, said she was happy to see that many of the concerns voiced by students in the group had been resolved with the recent changes. Many of her peers desired more intermediate classes before the change, classes were split between lower level introductory classes and higher level classes, she said.

I dont think the changes are very drastic, but noticeable in a good way, Alpert said.

Though she was a part of the focus group, Alpert said she is unaware of what all the changes entail. She added there will be a discussion for undergraduates on Nov. 14 about the changes. A new committee will also be formed to review the current curriculum.

Elon Musk warns against unleashing artificial intelligence 'demon'

NEW YORK (CNNMoney)

Musk, who promises to take humans to new heights with space and battery technologies, was especially grounded in his latest caution on artificial intelligence.

He told an audience at MIT on Friday that "we should be very careful about artificial intelligence," warning it may be "our biggest existential threat."

"With artificial intelligence, we are summoning the demon," he said.

"In all those stories where there's the guy with the pentagram and the holy water, it's like yeah he's sure he can control the demon," he continued, to some laughs from the audience.

Musk then cracked a smile: "Didn't work out."

His Tesla (TSLA) electric vehicles and SpaceX rockets, which recently won a multi-billion dollar contract with NASA, have pushed the limits of their respective technologies.

Musk hasn't embraced artificial intelligence, a field of study at MIT and other schools with significant ethical considerations and business potential. He has previously cautioned it is "potentially more dangerous than nukes."

But he has invested in artificial intelligence companies -- because, he told CNN's Rachel Crane recently, he wanted "to keep an eye on them."

"I wanted to see how artificial intelligence was developing," Musk said in the CNN interview. Among his questions: "Are companies taking the right safety precautions?"

We are 'summoning the demon' with AI: technologist Elon Musk

Thispostwas originally published onMashable.

There have already been several dire warnings fromTeslaandSpaceXfounderElon Muskin recent months regarding the perils of artificial intelligence, but this week he actually managed to raise the bar in terms of making AI seem scary.

First, according to Musk, AI was as dangerousas nuclear war. Now Musk is likening the possible battle between humans and computers in the future, termed by some as "the singularity," as a struggle for the soul of mankind itself.

How so? By invoking the one thing even those with little interest in technology fear the most: demons!

In an hour-long interview for MIT, which held itsCentennial Symposiumlast week, Musk opened himself up to the audience for questions. Most of the questions were about space travel, but one audience member asked Musk for his thoughts on artificial intelligence, and that's when things got a bit spooky.

"I think we should be very careful about artificial intelligence," said Musk, the expression on his face suddenly turning very serious. "If I were to guess like what our biggest existential threat is, it's probably that. So we need to be very careful with the artificial intelligence. There should be some regulatory oversight maybe at the national and international level, just to make sure that we don't do something very foolish."

Sounds reasonable. Prudent even. A generally conservative approach to a potential technological issue facing our world in the future. Wise words.

CAMBRIDGE, Mass.

It's hard to call Elon Musk a technophobe the Tesla CEO has been a vocal proponentofspace exploration, the electric carand something called a "hyperloop."

But there's one bit of future techMusk isn't so keen on: artificial intelligence. And duringa recentMITaerospace symposium, Musk issued a gravewarning about the potentialdangers of AI research.

"With artificial intelligence, we are summoning the demon. You know all those stories where there's theguy with thepentagram and the holy water, and he's like, yeah, he's sure he can control the demon. Doesn't work out."

Of course, we've all seen plenty of big-budget sci-fi warnings about havoc-wreaking robots, but Muskhas actually been pretty consistent with his AI phobia.

Elon Musk Makes Bizarre Matrix-Style Prediction

Elon Musk, Internet darling and CEO of Tesla Motors, was speaking before the MIT Aeronautics and Astronautics departments Centennial Symposium on Friday. In the middle of his session, he distractedly mused on some foreboding thoughts about artificial intelligence.

I think we should be very careful about artificial intelligence. If I were to guess like what our biggest existential threat is, its probably that. So we need to be very careful with the artificial intelligence.

Increasingly scientists think there should be some regulatory oversight maybe at the national and international level, just to make sure that we dont do something very foolish.

With artificial intelligence we are summoning the demon. In all those stories where theres the guy with the pentagram and the holy water, its like yeah hes sure he can control the demon. Didnt work out.

This is not the first time that Musk has issued a warning about artificial intelligence. Back in August he tweeted:

Musk referenced Superintelligence by Bostrom, evidently referring to Superintelligence: Paths, Dangers, Strategies by Nick Bostrom, a recent book.

The Amazon description for Bostroms book reads:

Superintelligence asks the questions: What happens when machines surpass humans in general intelligence? Will artificial agents save or destroy us?

If machine brains surpassed human brains in general intelligence, then this new superintelligence could become extremely powerful possibly beyond our control. As the fate of the gorillas now depends more on humans than on the species itself, so would the fate of humankind depend on the actions of the machine superintelligence.

Most of what lay persons know about artificial intelligence and the dangers therein lies in movies like The Matrix and the Terminator films and television show. In these imaginings, artificial intelligence grows controlled until it reaches a tipping point where it quickly outpaces mans ability to control it. It progresses on, unfeeling and cold, reasoning that man is too flawed and weak to be depended upon as a facet of its existence. It then seeks to either eliminate or subjugate humans.

Elon Musk: 'We are summoning the demon' with artificial intelligence

While he believes smart machines can take us to Mars and drive our cars for us, Musk remains worried that artificial intelligence holds a darker potential.

Musk says this guy could be the least of our fears. Video screenshot of "Far Cry 3" by CNET Australia

Elon Musk, a chief advocate of cars smart enough to park and drive themselves, continues to escalate his spooky speech when it comes to the next level of computation -- the malicious potential of artificial intelligence continues to freak him out.

"With artificial intelligence, we are summoning the demon," Musk said last week at the MIT Aeronautics and Astronautics Department's 2014 Centennial Symposium. "You know all those stories where there's the guy with the pentagram and the holy water and he's like... yeah, he's sure he can control the demon, [but] it doesn't work out."

This has become a recurring theme in Musk's public comments, and each time he warns of the AI bogeyman it seems even more dire.

In June, Musk raised the specter of the "Terminator" franchise, saying that he invests in companies working on artificial intelligence just to be able to keep an eye on the technology. In August, he reiterated his concerns in a tweet, writing that AI is "potentially more dangerous than nukes." Just a few weeks ago, Musk half-joked on a different stage that a future AI system tasked with eliminating spam might decide that the best way to accomplish this task is to eliminate humans.

But this is the first time I'm aware of that Musk has kicked up the rhetoric another notch -- perhaps anticipating this week's onslaught of Halloween costumes -- to compare AI to something supernatural like demons.

How to deal with the demonic forces of AI in the future? In a strange move for a tech mogul, Musk suggests it might be a good idea to fight one bogeyman with another (depending on your political perspective) in the form of government regulators.

"If I were to guess at what our biggest existential threat is, it's probably that," he said, referring to artificial intelligence. "I'm increasingly inclined to thing there should be some regulatory oversight, maybe at the national and international level just to make sure that we don't do something very foolish."

Indeed. Who knows what demonic hellscape could emerge if we ever let artificially intelligent machines get ahold of a Ouija board. Watch Musk's comments for yourself in the video below.

The Margin: Elon Musk warns of our biggest existential threat

Elon Musk just got biblical on the topic of artificial intelligence. In fact, he called it our biggest existential threat. This from a man working hard to make it possible for you to take a snooze behind the wheel during your morning commute.

With artificial intelligence, we are summoning the demon, the Tesla TSLA, -0.02% boss said Friday in an interview at MIT (see video above). In all those stories where theres the guy with the pentagram and the holy water, its like, hes sure he can control the demon.

And, as Musk pointed out, that usually doesnt work out so well.

Whether some sort of Terminator-style Judgment Day awaits us draws a varied response, depending upon whom you ask. Cambridge professor and heralded physicist Stephen Hawking, for instance, is in Musks camp, saying AI may turn out to be our best and last creation.

Then theres tech entrepreneur and venture capitalist Marc Andreesen, who tweeted that hes increasingly convinced [Musk] simply doesnt know what hes talking about and that anybody feeling freaked out about it should read this piece from the engineering geeks at IEEE Spectrum.

Andreesen joked that hell start to worry when iPhone autocorrect starts to work reliably.

As for Musk, he responded to Andreesen with: Famous last words. Actually, they would be famous if there were any humans left alive to hear them. And with that, he went even deeper with his most recent tweet.
