Just released: LinkedIn’s 2017 U.S. Emerging Jobs Report | LinkedIn Economic Graph Team

"The job market in the U.S. is brimming right now with fresh and exciting opportunities for professionals in a range of emerging roles" inform LinkedIn Economic Graph Team.


New types of jobs means new potential for workers at all levels, especially for those looking to change careers. Overall, job growth in the next decade is expected to outstrip growth during the previous decade, creating 11.5 million jobs by 2026, according to the U.S. Bureau of Labor Statistics.

Even further, it’s estimated that 65% of children entering primary school today will ultimately hold jobs that don’t yet exist.

To help find those up-and-coming roles and to better understand what skills are needed to succeed, we analyzed LinkedIn data from the last five years, as well as some survey data, to identify which jobs and skills are on the rise, what they’re replacing, and what these trends indicate about the jobs market in the years to come.

Here’s what we found:
  • Tech is king: Jobs with the top growth potential are tech-focused, with demand coming from tech and non-tech companies alike. Machine learning engineer, data scientist, and big data engineers rank among the top emerging jobs -- with companies in a wide range of industries seeking those skills.
  • Soft skills matter: Not all of the emerging tech jobs require technical skills. Sales development representative, customer success manager, and brand partner rank among the top emerging jobs at companies where a technical background is not a necessity. Traditional soft skills like communication and management underpin all of these emerging jobs.
  • Jobs with high mobility on the rise: Several top emerging jobs reflect broader societal trends, such as wellness, flexibility and location mobility. More people are getting healthy which could explain why barre instructor featured among our emerging jobs. Not quite as surprising, licensed realtors ranked highly as the post-Great Recession recovery of the real estate market rolls forward. Just in the past year, the number of licensed realtors has surged 40 percent. These type of roles tend to be more widely distributed across U.S. regions.
  • Low supply of talent for top jobs: Data scientist roles have grown over 650 percent since 2012, but currently 35,000 people in the US have data science skills, while hundreds of companies are hiring for those roles - even those you may not expect in sectors like retail and finance - supply of candidates for these roles cannot keep up with demand.
  • Future-proofing skills is critical: Some of these emerging skills didn’t even exist five years ago, and many professionals are not confident their current skill set will be relevant within the next 1-2 years.
Read on to see how skills and experience might play into the jobs of tomorrow, and the paths to get there.

The explosion of tech roles over the past five years comes as no surprise given the impact of technology in every sector. Our November Workforce Report noted that hiring is up nearly 10% in the hardware industry, and nearly 15% in the software industry from October 2016.
  • Specifically, the growth and widespread application of more sophisticated technology - like artificial intelligence - we are seeing more specialized machine learning and data-specific roles top the list of emerging jobs. These jobs are also widely available outside the technology industry.
  • The number of customer experience roles that made the list indicates that the “age of the customer” was more than jargon. These jobs are among some of the non-automatable jobs on the market today, and the skills associated with them aren’t necessarily taught in university, as they rely heavily on soft skills.
There can’t be emerging jobs without some jobs being replaced. When looking at the roles that are starting to lose steam in today’s professional landscape, two trend stands out:
  • Comprehensive sets of skills that cover multiple disciplines are seemingly in higher demand. Many of the roles on this list cover multiple disciplines and are applicable to multiple industries.
  • Certain specialist roles are on the decline. From specialized developer roles, to legal specialists, and even specialized logistics roles, we are seeing these roles be replaced in favor of more comprehensive skill sets and job titles. For example, Flash-related roles are on the decline as the technology loses steam in favor of more big data and machine learning roles.
We looked back at the career paths of professionals who hold these top 5 roles to get a sense for where they were in their careers 5 years ago, and what we found is encouraging for professionals no matter their career journey or the types of skills they have.
  • In analyzing the career path of professionals who hold one of the top 5 emerging jobs, there was a common thread throughout: software engineers are feeding into all of the technology-related professions.
  • Sales Development Representatives, while growing rapidly, is still an entry-level role and a great option for those looking to break into any industry. In fact, this is one of the most popular roles for recent graduates.

Methodology: The results of this analysis represent the world seen through the lens of LinkedIn data. As such, it is influenced by how members choose to use the site, which can vary based on professional, social, and regional culture, as well as overall site availability and accessibility. These variances were not accounted for in the analysis.

We looked at all members who list dated work experience on their profile and grouped the millions of unique, user-inputted job titles based on common job roles (which have many permutations). For example, the “machine learning engineer” job title includes user inputted titles such as “machine learning software engineer” and “machine learning engineer II.” We then counted the frequencies of job titles that were held in 2012 and compared the results to job titles that were held in 2017. “Emerging jobs” refers to the job titles that saw the largest growth in frequency over that 5 year period.

Composer incorporates math and art in McBain music | Cadillac News

Photo: Karen Hopper Usher
"Composing is alive and instrumental music isn't just recycled from the past" summarizes Karen Hopper Usher, Cadillac News.



Composers like Andrew Perkins are constantly writing new tunes for young musicians.

The challenge is to write a piece of music that gets kids to really think.

In January, middle school band students at McBain Rural Agricultural School will perform Perkins's piece, "Gradients," at the Michigan Music Conference.

When Perkins saw a Cadillac News article about McBain's upcoming performance, he contacted band teacher Heather Wiggins to congratulate her.

He also had a proposition — He had a recently completed composition. Would her students be interested in debuting the music at the conference?

Yes, they would.

"For composers, performances at big conferences are a big deal," Perkins said. "It's kind of a win-win."

Perkins, who teaches music in Fenton, near Flint, understands the complexities of finding music that's appropriate for middle school musicians, suits the instrumental make-up of the band and is entertaining.

A lot of middle school band literature isn't written "about anything," Perkins said. It's music for the sake of teaching a specific musical concept.

Perkins wanted to teach something more sophisticated, he said.

He settled on the idea of gradients, which has different but related applications in mathematics, physics, philosophy and art. The mathematic concept of "rise over run," is something kids tend to learn in middle school math, he said...

...perform Perkins's pieces at the Michigan Music Conference in January. Besides McBain, Warren Mott will perform "Alcatraz" and Okemos will perform "Asylum," which is about the old asylum in Traverse City.

5 Reasons that Electric Bikes Are Like Blended Learning | Inside Higher Ed - Technology and Learning

Follow on Twitter as @joshmkim
"My new obsession is electric bikes. Not that I own one." says Dr. Joshua Kim, Director of Digital Learning Initiatives at the Dartmouth Center for the Advancement of Learning (DCAL).
 
Technology and Learning

Being an academic, I’ll need to do 10,000 hours of research before I am comfortable contemplating any action. At this rate, I expect to be in the market for an e-bike purchase in spring of 2018.


Electric bike
Like all my obsessions, I understand electric bikes through the lens of learning and technology.

Here are 5 ways that electric bikes are exactly like blended learning:

1 - The Passion of Early Adopters:
A growing number of my colleagues are commuting to campus on an electric bike. They are replacing a drive to campus in a car with a ride to campus on an e-bike. Reasons vary. Some are riding their electric bike because they live too far away to ride a traditional bicycle. Others ride their e-bike to campus because they can arrive without getting sweaty, avoiding the need to shower. What all of these electric bike owning colleagues have in common is their passion for e-bikes. They are electric bike evangelists. They talk about how their e-bike changed their life. Not only do they get more exercise, they look forward to their morning and early evening ride. The purchase price of the e-bikes were justified by saving on the parking passes and gas, but these practical commuting decisions gave rise to a larger belief that electric biking is the future of transportation.

We hear much the same things from those educators who have gotten into blended learning. Talk to faculty teaching online courses, and they marvel at how the medium enables them to deeply interact with their students. The asynchronous nature of much of online learning creates space for all the students in the class to contribute to discussions and debates - through the mechanisms of discussion boards and blogs and wikis - space that is normally constrained and finite in a traditional 50 or 90 minute residential class. Flipping a mostly residential course, by having course content and curriculum be delivered before the class through online lectures, creates new space in the face-to-face discussion for active learning.  Class is invigorating when the teaching model moves from delivering content to coaching and mentoring.

2 - A Dedicated Community of Practice:
The small and growing number of electric bike people on my campus have started to find one another. They are meeting to talk about how they chose their e-bike, where they get it serviced, and what rides in the area (with big hills) they are now willing to tackle. These campus electric bike pioneers are starting to convert others. There seems to be many more of us who are talking about getting an e-bike than who actually own one.  The enthusiasm of these early electric bike owners is contagious.

This small group of e-bike converts reminds me of those faculty who were amongst the first to teach online and to use technology to flip their residential classes. The first professors to make the transition to online and blended learning faced a good degree of skepticism from their colleagues. Most were skeptical themselves. They wondered if technology would get in the way of what they love best about teaching. They worried about what would be lost when eye contact was replaced by screen time. When the give and take of a good lecture was substituted for recorded video presentations and discussion boards.

What most faculty found, to their surprise, was that online and blended teaching is pretty great. Maybe not better than traditional face-to-face teaching, but usually better than a straight lecture based (large enrollment) course. Online and blended learning encouraged, rather than inhibited, interactions with students.  The medium of online and blended learning still required all the expertise of an experienced educator. The difference being that now online faculty could teach students who were also full-time workers, who were unable to move to campus, and who relied on online learning to participate in higher education. For those teaching blended courses, the technologies of classroom flipping opened up more time for active learning and intensive instruction.

Daemon Voices review – wise words from a craftsman | The Guardian - Books + Reviews


"Philip Pullman’s collection of insightful essays on the power of storytelling." 

Daemon essayist: Philip Pullman.
Photo: Suki Dhanda for the Observer
Published alongside La Belle Sauvage, the first in a three-part prequel to His Dark Materials, Daemon Voices is a compendious collection of Philip Pullman’s talks, essays and newspaper articles spanning several decades. 

Exploring themes as diverse as art, politics, science and faith, Pullman is eloquent on the craft and power of storytelling and the folk tales and fairytales that are his personal touchstones.

A lecture entitled “Let’s write it in red”, inspired by two little girls writing a story together on a train, reflects on the need to “keep the old stories burnished and bright and new by telling them over and over again”. Something of this telling and retelling is revealed in the themes, images and literary allusions that repeat like refrains throughout the collection, offering an insight into Pullman’s own creative preoccupations.
 
Daemon Voices

2017: A Year To Remember | Phoenix Conservatory of Music (PCM)

”I’ve been involved since I was seven or eight. Ever since then, I’ve been building my skills.” 

Phoenix Conservatory of Music named as an Arizona State Charitable Tax Credit Organization, Phoenix Conservatory of Music’s College Prep Program serving the Phoenix Metropolitan Area cited as one of the best creative youth development programs in the country and wins a National Arts and Humanities Youth Program Award, and Phoenix Conservatory of Music Wins Mayor’s Arts Award!

Will Kratzenberg, a sophomore in High School and PCM student says. “[I started with piano and then went to audio production.] I had no place to go for sound production or learn how to build or reconstruct sound. PCM showed me how to work inside sound production DAWs and how to mix and even create my own songs. At first, I thought it wouldn’t be all that great…all these people doing what I’m doing. If anything, that is the key to learning- learning what people are doing around you, learning from them and taking some of their knowledge into your own. I feel a sense of family here.  Coming here is an escape and you can really improve your skills being here and learning with your family.  [As a family] we are being able to build what we’ve been trying to build for a very long time.  [As an organization], we finally made it up there, and after all these years …it’s finally paying off.”

And this is the absolute truth.  This has been an incredible year for Phoenix Conservatory of Music, a Phoenix based nonprofit community school of music with a very big reach.  “It often feels as if we are a very best kept secret”, says Regina Nixon, Executive Director of Phoenix Conservatory of Music, ”but we have amazing stories with all of our students and some fantastic outcomes.”

This past November, at a special ceremony in Washington, D.C. this November, the nation’s top cultural agencies honored twelve Creative Youth Development programs from across the country for their work in providing excellent arts and humanities learning opportunities to young people.  Three of Phoenix’s own students had the honor of traveling to our Nation’s Capital to represent Phoenix, Arizona and a top after school arts program, Phoenix Conservatory of Music’s College Prep Program. Marcus Wolf (17), Michael Rodriguez (15) and Lourde Childs (13) were the student representative and performers for The Phoenix Conservatory of Music as it was recognized with a 2017 National Arts and Humanities Youth Program Award.  The award was presented by The National Endowment for the Arts and their partners.  Michael and Lourde, the only two performers for this prestigious Washington D.C. awards ceremony, performed Man In The Mirror recorded by Michael Jackson, written by Glen Ballard and Siedah Garrett; produced by Quincy Jones, and received a standing ovation.  (Video of the performance: https://youtu.be/QXC2YNMWLVQ?t=30m35s )

The award honors the nation’s highest best programs for after school arts and humanities programs. Chosen from 350 nominations from across the country, PCM, was one of twelve organizations across the country to receive the honor, which recognizes effectiveness in promoting learning and life skills in young people by engaging them through creative youth development programs.
“Phoenix is home to an incredible arts community, and organizations like the Phoenix Conservatory of Music are key to the city’s cultural vibrancy,” Phoenix Mayor Greg Stanton said. “This award is testament to the great work PCM is doing to expose children in our community to the arts and music education.”

The award is the latest recognition to highlight the Conservatory’s work with students. Earlier this year, Phoenix Conservatory of Music was a recipient of the 2017 Mayor’s Arts Awards for Innovative Organization of the Year, and in 2015 received the Arizona Governor’s Arts Award for Arts Education Organization.  In addition to all of the accolades, there are the direct outcomes of the program- a 95% High School Graduation Rate, 71% attend college or university, and in the last 7 years, they have earned over $1M+ in addition to scholarship offers.

How To Start A Data Science Career As An Undergrad | Forbes

"How do I choose an internship that prepares me for a data science career as an undergraduate student? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the world." Quora, Contributor.

Answer by Alex Francis, Data Scientist, on Quora:

Photo: Hemant Mishra/Mint via Getty Images

How do I choose an internship that prepares me for a data science career as an undergraduate student? 

I think the answer to this question really depends on the company/role/industry combination, but if your background resembles my own, I’ll take a stab at the question.

To start, I strongly believe that completing an internship is more valuable than an “ML related summer research project,” unless that research is done in the context of a respected laboratory at your university, and you have the explicit goal of publishing a paper that will help you gain admission to top graduate programs in machine learning. With that said, while internship roles in data science at tech companies are plentiful (see, for example, What companies have data science internships for undergraduates?), finding companies that actively hire undergraduates is non-trivial (in my experience). You’ll need to be aggressive, sometimes applying for and following up with recruiters on roles in which a graduate degree is “recommended” or even “required.” Finding companies that are willing to take a chance on a younger candidate will be an inevitable filter - luckily, several great companies are willing to engage with undergraduates. I evaded this artificial barrier by interning as a “data engineer,” and working on infrastructure related to the data science team. This gave me valuable insights into the day-to-day efforts of a data scientist.

Secondly, I highly recommend choosing to work on a product with which you have some familiarity. This is the most underrated element of the decision-making process, in my opinion. As a data scientist, you will constantly be called upon to generate and test hypotheses about the product, produce insights, and suggest future directions. If you’re an active user of the product, this isn’t nearly as difficult — in fact, it’s often fun! Targeting companies that create products you love will make you a better interviewer and a better employee...

To summarize, successfully navigating a data science career is probably not so different than managing a career in any other field: set some goals, be aggressive, know your worth, figure out what’s fun and what isn’t, reset those goals, and repeat the cycle. 
Best of luck!

NASA Explores Artificial Intelligence for Space Communications | NASA

"NASA spacecraft typically rely on human-controlled radio systems to communicate with Earth. As collection of space data increases, NASA looks to cognitive radio, the infusion of artificial intelligence into space communications networks, to meet demand and increase efficiency" continues NASA.

This photo was taken of NASA's Space Communications and Navigation Testbed before launch. Currently affixed to the International Space Station, the SCaN Testbed is used to conduct a variety of experiments with the goal of further advancing other technologies, reducing risks on other space missions, and enabling future mission

“Modern space communications systems use complex software to support science and exploration missions,” said Janette C. Briones, principal investigator in the cognitive communication project at NASA’s Glenn Research Center in Cleveland, Ohio. “By applying artificial intelligence and machine learning, satellites control these systems seamlessly, making real-time decisions without awaiting instruction.”

To understand cognitive radio, it’s easiest to start with ground-based applications. In the U.S., the Federal Communications Commission (FCC) allocates portions of the electromagnetic spectrum used for communications to various users. For example, the FCC allocates spectrum to cell service, satellite radio, Bluetooth, Wi-Fi, etc. Imagine the spectrum divided into a limited number of taps connected to a water main.

What happens when no faucets are left? How could a device access the electromagnetic spectrum when all the taps are taken?

Software-defined radios like cognitive radio use artificial intelligence to employ underutilized portions of the electromagnetic spectrum without human intervention. These “white spaces” are currently unused, but already licensed, segments of the spectrum. The FCC permits a cognitive radio to use the frequency while unused by its primary user until the user becomes active again.

In terms of our metaphorical watering hole, cognitive radio draws on water that would otherwise be wasted. The cognitive radio can use many “faucets,” no matter the frequency of that “faucet.” When a licensed device stops using its frequency, cognitive radio draws from that customer’s “faucet” until the primary user needs it again. Cognitive radio switches from one white space to another, using electromagnetic spigots as they become available.

“The recent development of cognitive technologies is a new thrust in the architecture of communications systems,” said Briones. “We envision these technologies will make our communications networks more efficient and resilient for missions exploring the depths of space. By integrating artificial intelligence and cognitive radios into our networks, we will increase the efficiency, autonomy and reliability of space communications systems.”

For NASA, the space environment presents unique challenges that cognitive radio could mitigate. Space weather, electromagnetic radiation emitted by the sun and other celestial bodies, fills space with noise that can interrupt certain frequencies.

“Glenn Research Center is experimenting in creating cognitive radio applications capable of identifying and adapting to space weather,” said Rigoberto Roche, a NASA cognitive engine development lead at Glenn. “They would transmit outside the range of the interference or cancel distortions within the range using machine learning.” 

In the future, a NASA cognitive radio could even learn to shut itself down temporarily to mitigate radiation damage during severe space weather events. Adaptive radio software could circumvent the harmful effects of space weather, increasing science and exploration data returns.

Writing Music with the Mind: New BCI Modality Offers the Power to Make Music as well as Play It | Evolving Science - Computer Science & Technology

Photo: Deirdre O’Donnell
"Brain-computer interfaces (BCIs) that allow people with severe neuromotor or motor disorders to communicate are becoming more and more common" says Deirdre O’Donnell, professional writer for several years. Deirdre is also an experienced journalist and editor.

This is realised by scanning brainwaves using electroencephalography (EEG) and converting them accurately into words, letters or other objects that the user intends to replicate in their minds. BCIs are beneficial for those with extensive paralysis, ‘locked-in’ syndrome and other similar conditions.

EEG-powered BCIs have a number of advantages; it is non-invasive, (the brainwaves are ‘picked up’ through the skull using electrodes integrated into a head-hugging cap) well-validated, well recognized, and often relatively cheap. In addition, certain ranges of brainwave (or event-related potentials (ERPs), as some are also known) have also been exhaustively studied and exploited for the purposes of BCI. They include the posterior-dominant rhythm, which is associated with the high-fidelity selection of notes and other musical objects on virtual instruments, and the P300 wave that enables patients to complete tasks such as selecting numbers in a BCI interface. As such, some researchers suggest that P300 could also be used to specify and select musical notes in those who need to write music using BCI. A recent study published in PLOS One suggests that this is indeed possible. This is good news for patients who want to write their own music completely hands-free as well as play it.

Composing music through thoughts 
This team, based at the Institutes of Neural Engineering and Psychology at Graz University of Technology, developed a BCI interface that was also loaded with software supporting musical composition. They based their work on existing BCIs that allow patients to paint using software somewhat similar to many conventional drawing or art apps found on everyday computers, and also previous studies that showed a 75 percent accuracy rate in selecting notes from the C major scale using a modified BCI spelling programme. The team, supervised by Gernot Müller-Putz of the Neural Engineering institute, hypothesised that such BCI musical composition was also applicable to a more extensive range of options. In other words, they linked their EEG receivers to the full musical composition suite MuseNote. A previous pilot study evaluating this approach in five healthy individuals found that this group could input a given melody into the software via the BCI with an accuracy of up to approximately 96 percent, although 40 percent of them could complete the task at an accuracy of about 50 percent. Therefore, the group designed a new experiment in which they recruited 18 healthy volunteers with musical backgrounds, including a professional composer, to test their ability to spell, write a full, pre-determined melody and compose original sequences using this BCI system.

MuseScore 2.0 Preview


The team used a fairly conventional BCI system, which consist of EEG detection and recording hardware, P300-wave-based software (written largely in C with Matlab for signal processing) and the MuseNote software, which was controlled in turn by the P300 software.

But What If They Cheat? Giving Non-Proctored Online Assessments | Faculty Focus - Online Education

"As online education continues to grow, so does the potential for academic dishonesty" summarizes Sheryl Cornelius, registered nurse who has been teaching for the last 15+ years in universities and community colleges.

Photo: Faculty Focus

So how do you ensure your online students are not cheating on their tests? Bottom line, you don’t. But there are ways to stack the deck in your favor.

The good news is it’s not as bad as you think. A 2002 study by Grijalva, Kerkvliet, and Nowell it found that “academic dishonesty in a single online class is no more prevalent than in traditional classrooms” (Paullet, Chawdhry, Douglas & Pinchot, 2016, pg. 46). Although the offenders have become quite creative in their endeavors, the prevention remains the best defense.

First, start by creating a culture of integrity. Many institutions have students review the school’s Honor Code and sign a “pledge.” The first question on every exam I give is True/False, “I will follow the Honor Code while taking this assessment.” It follows the similar rule that locked doors are for honest people, but it also serves as a good reminder of the possible consequences, which often is enough to keep many students from breaking the rules.

Second, do not set rules that you have no way to enforce, e.g. forbidding the use of books, notes, or other resources. Instead ask questions that will not be evident in the resources, such as items where students have to analyze, evaluate, and think critically about the content. Essay questions, case study analysis, fill in the blanks, sequencing questions, and hot spot questions are difficult to look up. It also helps to set a time limit for the test so that Googling answers becomes impossible.

Third, make every assessment different. No, I am not saying create 25 exams, but you can scramble questions and create multiple versions of the same test. If everyone finishes the exam with an essay question, you can create three different questions and have one randomly assigned to each exam. If you have deep enough test banks, you can have several different test versions with no question being repeated. Anything you can do to mix up the versions can detour efforts of deceitful activity.

Many instructors withhold feedback until the exam has closed. In this way no one can pass on answers to others. Some will have the exam synchronous for this very reason. However, making the exam synchronous takes away the flexibility for online students that work unusual shifts.

Forget about today’s modest incremental advances in artificial intelligence, such as the increasing abilities of cars to drive themselves.

Waiting in the wings might be a groundbreaking development: a machine that is aware of itself and its surroundings, and that could take in and process massive amounts of data in real time. It could be sent on dangerous missions, into space or combat. In addition to driving people around, it might be able to cook, clean, do laundry – and even keep humans company when other people aren’t nearby. 

A particularly advanced set of machines could replace humans at literally all jobs. That would save humanity from workaday drudgery, but it would also shake many societal foundations. A life of no work and only play may turn out to be a dystopia. 

Conscious machines would also raise troubling legal and ethical problems. Would a conscious machine be a “person” under law and be liable if its actions hurt someone, or if something goes wrong? To think of a more frightening scenario, might these machines rebel against humans and wish to eliminate us altogether? If yes, they represent the culmination of evolution. 

As a professor of electrical engineering and computer science who works in machine learning and quantum theory, I can say that researchers are divided on whether these sorts of hyperaware machines will ever exist. There’s also debate about whether machines could or should be called “conscious” in the way we think of humans, and even some animals, as conscious. Some of the questions have to do with technology; others have to do with what consciousness actually is. 

Most computer scientists think that consciousness is a characteristic that will emerge as technology develops. Some believe that consciousness involves accepting new information, storing and retrieving old information and cognitive processing of it all into perceptions and actions. If that’s right, then one day machines will indeed be the ultimate consciousness. They’ll be able to gather more information than a human, store more than many libraries, access vast databases in milliseconds and compute all of it into decisions more complex, and yet more logical, than any person ever could. 

On the other hand, there are physicists and philosophers who say there’s something more about human behavior that cannot be computed by a machine. Creativity, for example, and the sense of freedom people possess don’t appear to come from logic or calculations. 

Yet these are not the only views of what consciousness is, or whether machines could ever achieve it. 

Another viewpoint on consciousness comes from quantum theory, which is the deepest theory of physics. According to the orthodox Copenhagen Interpretation, consciousness and the physical world are complementary aspects of the same reality. When a person observes, or experiments on, some aspect of the physical world, that person’s conscious interaction causes discernible change. Since it takes consciousness as a given and no attempt is made to derive it from physics, the Copenhagen Interpretation may be called the “big-C” view of consciousness, where it is a thing that exists by itself – although it requires brains to become real. This view was popular with the pioneers of quantum theory such as Niels Bohr, Werner Heisenberg and Erwin Schrödinger. 

The interaction between consciousness and matter leads to paradoxes that remain unresolved after 80 years of debate. A well-known example of this is the paradox of Schrödinger’s cat, in which a cat is placed in a situation that results in it being equally likely to survive or die – and the act of observation itself is what makes the outcome certain. 

The opposing view is that consciousness emerges from biology, just as biology itself emerges from chemistry which, in turn, emerges from physics. We call this less expansive concept of consciousness “little-C.” It agrees with the neuroscientists’ view that the processes of the mind are identical to states and processes of the brain. It also agrees with a more recent interpretation of quantum theory motivated by an attempt to rid it of paradoxes, the Many Worlds Interpretation, in which observers are a part of the mathematics of physics. 

Philosophers of science believe that these modern quantum physics views of consciousness have parallels in ancient philosophy. Big-C is like the theory of mind in Vedanta – in which consciousness is the fundamental basis of reality, on par with the physical universe.

16th annual New College holiday book guide | Sarasota Herald-Tribune

Each year, the Herald-Tribune invites faculty, administrators and staff at New College of Florida to recommend books to our readers that had a particular impact on them. They don’t have to be new.

Would you like to choose a gift that inspires someone to think about life’s most important questions? Many of this year’s books explore the challenges of understanding our relationship to the past, achieving wisdom or practical success, or remaking the world by opening ourselves to new ideas. Authors reevaluate the New Deal, examine the religious revival in China, lay out 34 plans for newly enlightened national policies, or rescue the skills of their ancestors from being erased by history. Literary works range from the grim humor of historical fiction to a blend of fantasy and reality in an environmental novel. In graphic novels from different cultures, authors reinvent “Frankenstein” by portraying a black scientist reanimating her child, or reimagine Frankenstein as a creature made of war dead in the Arab world.

Wishing everyone a year filled with rewarding books, we present the 16th annual New College Holiday Book Guide, with reviews compiled by English professor Andrea Dimino.

The recent book “Prime Numbers and the Riemann Hypothesis” (Cambridge University Press, 2016) by Barry Mazur and William Stein, two accomplished mathematicians and fine prose stylists, will make a great gift for a curious student. Using the graphical methods found in calculus reform texts, this beautiful little book allows a patient reader with a good grasp of first-year calculus to explore the most famous unsolved problem in mathematics, the so-called Riemann Hypothesis, and to understand why it points to as yet undiscovered regularities in the distribution of prime numbers.

Bernhard Riemann introduced the hypothesis in 1859 in a brief, dazzling paper that seems to have come out of some strange alien universe. The Riemann Hypothesis has since become the Holy Grail for generations of mathematicians, and continues to resist all attempts at solution. The process of establishing weaker variants has resulted in major mathematical advances, and made careers. Until now, however, the deeper significance of the hypothesis has been inaccessible to those without advanced mathematical training. Mazur and Stein’s book fixes that, and is itself a first-rate intellectual achievement.
