The Peculiar Math That Could Underlie the Laws of Nature | Mathematics - Quanta Magazine

"New findings are fueling an old suspicion that fundamental particles and forces spring from strange eight-part numbers called “octonions.”" argues Natalie Wolchover, senior writer and editor at Quanta Magazine covering the physical sciences.

In 2014, a graduate student at the University of Waterloo, Canada, named Cohl Furey rented a car and drove six hours south to Pennsylvania State University, eager to talk to a physics professor there named Murat Günaydin. Furey had figured out how to build on a finding of Günaydin’s from 40 years earlier — a largely forgotten result that supported a powerful suspicion about fundamental physics and its relationship to pure math.
The suspicion, harbored by many physicists and mathematicians over the decades but rarely actively pursued, is that the peculiar panoply of forces and particles that comprise reality spring logically from the properties of eight-dimensional numbers called “octonions.”
As numbers go, the familiar real numbers — those found on the number line, like 1, π and -83.777 — just get things started. Real numbers can be paired up in a particular way to form “complex numbers,” first studied in 16th-century Italy, that behave like coordinates on a 2-D plane. Adding, subtracting, multiplying and dividing is like translating and rotating positions around the plane. Complex numbers, suitably paired, form 4-D “quaternions,” discovered in 1843 by the Irish mathematician William Rowan Hamilton, who on the spot ecstatically chiseled the formula into Dublin’s Broome Bridge. John Graves, a lawyer friend of Hamilton’s, subsequently showed that pairs of quaternions make octonions: numbers that define coordinates in an abstract 8-D space.

There the game stops. Proof surfaced in 1898 that the reals, complex numbers, quaternions and octonions are the only kinds of numbers that can be added, subtracted, multiplied and divided. The first three of these “division algebras” would soon lay the mathematical foundation for 20th-century physics, with real numbers appearing ubiquitously, complex numbers providing the math of quantum mechanics, and quaternions underlying Albert Einstein’s special theory of relativity. This has led many researchers to wonder about the last and least-understood division algebra. Might the octonions hold secrets of the universe?...

Peculiar Numbers
I met Furey in June, in the porter’s lodge through which one enters Trinity Hall on the bank of the River Cam. Petite, muscular, and wearing a sleeveless black T-shirt (that revealed bruises from mixed martial arts), rolled-up jeans, socks with cartoon aliens on them and Vegetarian Shoes–brand sneakers, in person she was more Vancouverite than the otherworldly figure in her lecture videos. We ambled around the college lawns, ducking through medieval doorways in and out of the hot sun. On a different day I might have seen her doing physics on a purple yoga mat on the grass.

Taking Risks in Your Teaching | Faculty Development - Faculty Focus

Reprinted from The Teaching Professor, 28.3 (2014): 7. © Magna Publications. All rights reserved.


Maryellen Weimer, PhD, Author at Faculty Focus reports, "Often in workshops when I’m speaking about the process of implementing change—deciding what to change and how to change it or considering whether to add a new instructional strategy—the question of risk lurks in the choices being considered."
 
Photo: Faculty Focus
When attending a workshop or program that offers a range of instructional possibilities, teachers typically respond to some favorably. I see it—they write down the idea, nod, or maybe ask a follow-up question to be sure they understand the details. Not all the ideas presented get this favorable response. Occasionally, the response is overtly negative. But more often there is no response. The idea doesn’t resonate.

When I ask participants to look over their notes (I love teaching faculty because they do take notes) and share what criteria they used to select the new ideas they’re considering implementing, the responses are pretty nonspecific: “I liked it.” “It’s something I think I can do.” “I can use it when I’m teaching X.” I think they are really saying, “This approach fits comfortably with who I am and how I teach.” We first gravitate toward instructional changes that mesh with current practices and the content we teach. We choose them because we can see ourselves doing them...

Are some instructional approaches just too risky? Can teachers take on something they really shouldn’t be trying? Of course.

MTSU President Sidney A. McPhee and Shao Qianium, vice president of Ningbo University in China, agreed to extend the Joint Mathematics and Applied Mathematics Program, established in the fall of 2012, for 10 more years.

Ningbo students selected for the program first attend classes taught by MTSU faculty on the Chinese university campus, then progress to Murfreesboro to finish their studies. Successful students receive degrees from both MTSU and Ningbo University.

The program can accept up to 40 students each academic year.

“This partnership with Ningbo University is a model for effective and productive international academic cooperation,” McPhee said. “It leverages our respective strengths to provide unique opportunities for exceptional students.”

Replied Shao, quoting the renowned Chinese philosopher Confucius, “Isn’t it great when friends visit from distant places?”

Actuarial science trains students to apply mathematical skills and statistical techniques to manage risks and solve problems in insurance and pension programs.

MTSU, through its College of Basic and Applied Sciences, is the only Tennessee university offering actuarial science coursework for both undergraduate and graduate degrees.

Students take courses in mathematics, statistics, economics, and insurance designed to help prepare for preliminary examinations from the actuarial professional societies and to prepare them for success in the field.

The 10 Highest Paid Degrees | Business - Perfectly Plain

"While a bachelor’s degree isn’t the only avenue to obtain a job that gives us financial independence, it is a path that many teenagers and parents feel is an investment to transition into adulthood" according to Pawan Naidu, journalist from California.

However, when it comes to money, not all degrees are built the same. Your major largely determines your earning potential, and Payscale recently ranked majors based on alumni salaries.

Let’s take an in-depth look at the top 10 degrees, and whether the salary is going to be worth it.

(Note: Early Career Pay is the median salary for alumni with said degree with zero to five years of experience. Mid-Career Pay is the median salary for alumni with said degree with 10 plus years of experience.)

7. Economics and Mathematics
I’m not exactly sure if we’re ever going to need to trigonometry in our jobs or day-to-day life like are teachers told us, but having an advanced understanding of math helps the bank account. A person can expect to make around $60,000 a year soon after they graduate, and see a pay increase of $122,900 during the middle of their career. However, it needs to be mentioned that only 36 percent of alumni feel like they’re making a difference in the world.

According to Wake Forest, they have a program that combines these two majors and it allows students to apply mathematical methods to the development of economic theory, models and quantitative analysis...

3. Actuarial Science  
This major might not reap immediate benefits compared to previous ones on this list, but it makes up for it later on. Students majoring in actuarial science can expect to make $61,200 a year after graduation, and see more than double in pay increase in the middle of their career with $130,800. A little over 40 percent of alumni say they are doing something good in the world.

Actuarial science is statistical analysis involving mathematics, statistics and financial economics.

2. Actuarial Mathematics 
Actuarial mathematics is very similar to actuarial science. There is a difference in what they look at though. There is a slight pay decrease for starting salaries after graduation, but an increase when a person is in the middle of their career.
A recent graduate can expect to make $56,400 a year while receiving a significant pay increase to $131,700 later on. Almost half of the alumni feel their work is providing good in the world.

According to College Grad, actuaries working with math analyze the financial costs of risk and uncertainty. They use mathematics, statistics and financial theory to assess the risk of potential events, and they help businesses and clients develop policies that minimize the cost of that risk. Actuarial mathematicians’ work is essential to the insurance industry.

Students at Tara Anglican School for Girls will now learn their years 7 to 10 coursework via the International Baccalaureate (IB) Middle Years Program, a framework for teaching that the school introduced more than two years ago when students now in year 9 began their secondary schooling.

Head of Senior School Scott Baker says the content follows the Australian curriculum, but is taught differently. 

"The framework through which the material is taught is best practice," he says.

The IB middle years program (MYP) gives broad coverage in creative arts and design, language acquisition, literature, maths, physical education, societies and science...

A key part of IB study is learning how to take notes, how to reference and research. That's music to the ears of universities, some of whom have begun making unconditional early entry offers to IB students based on their predicted results.

Op-Ed: How Africa can embrace an artificial intelligence enabled future | CNBCAfrica.com

"Currently, no African country is among the top 10 countries expected to benefit most from AI and automation. But, the continent has the potential to catch up with the rest of world if we act fast" says Zoaib Hoosen, Microsoft Managing Director.


t’s no longer news that Artificial Intelligence (AI) will be a driving force behind the Fourth Industrial Revolution, with the global economic returns of this revolution expected to be in the region of about $16 trillion.

Along with these returns, AI is also expected to create 2.3 million new jobs by 2020, according to Gartner.

However, if we look at previous revolutions, history shows us that these revolutions have always been accompanied by a brief transition of temporary job loss followed by a period of recovery where job creation moves into more positive territory.

This means that we all need to take steps now to prepare AI in the future...

Combining STEM with the arts
Young people have a leg up on those already in the working world because they can easily develop the necessary skills for these new roles. It’s therefore essential that our education system constantly evolves to equip youth with the right skills and way of thinking to be successful in jobs that may not even exist yet.

As the division of tasks between man and machine changes, we must re-evaluate the type of knowledge and skills imparted to future generations.

For example, technical skills will be required to design and implement AI systems, but interpersonal skills, creativity and emotional intelligence will also become crucial in giving humans an advantage over machines.

“At one level, AI will require that even more people specialise in digital skills and data science. But skilling-up for an AI-powered world involves more than science, technology, engineering and math. As computers behave more like humans, the social sciences and humanities will become even more important. Languages, art, history, economics, ethics, philosophy, psychology and human development courses can teach critical, philosophical and ethics-based skills that will be instrumental in the development and management of AI solutions.” This is according to Microsoft president, Brad Smith, and EVP of AI and research, Harry Shum, who recently authored the book “The Future Computed”, which primarily deals with AI and its role in society.

Interestingly, institutions like Stanford University are already implementing this forward-thinking approach. The university offers a programme called CS+X, which integrates its computer science degree with humanities degrees, resulting in a Bachelor of Arts and Science qualification.

Want to change the world? Pursue research in the humanities… | University - Study International News

“The calling of the humanities is to make us truly human in the best sense of the word.” J. Irwin Miller


"From age-old sketches across cave walls to time-worn folklore tales, the humanities have long been mankind’s means of decoding a complex world" argues Study International News.

Our ancient ancestors recorded thoughts and feelings, created magnificent art, told fantastical stories and developed philosophical theories. Detailed research and analysis of these achievements reveal the intricate twists and turns of our past, offering a foundation that helps us understand and predict current and future trends.

When the relevance and credibility of this discipline comes under fire, it serves us well to take stock of its powerful legacy. Advancements in the humanities through the ages have come to define the very fabric of our existence. And since they have shaped the world today, they will greatly factor into our tomorrow.

But the world in which they were first conceived is fundamentally different to the one they’re used in now.

The current digital age is one centred on disruptive technologies, thriving on change and rapid-pace development. In this world, failure to adapt breeds the very real danger of becoming obsolete.

As the basis of all common knowledge we’ve come to discover, research in the humanities must continue to evolve to meet the challenges of life in the twenty-first century.

“Tackling today’s biggest social and technological challenges requires the ability to think critically about their human context, which is something that humanities graduates happen to be best trained to do,” explains Vivek Wadhwa of The Washington Post.

Research in the humanities has driven advances in diverse fields, from healthcare to robotics. Humanities graduates influence every major sector and tackle the greatest issues in our world, while leaders increasingly look for support from those who understand every layer of the human condition.

The masterminds who forge our path through the intricate turns of these disciplines are empowered by higher education. Statistics have revealed the humanities to hold the most popular subjects studied among global leaders.

Known for research excellence and technological innovation, Nanyang Technological University‘s (NTU) standing at number 12 in the QS World Ranking positions it among the global academic elite. Topping the QS Top 50 Under 50 chart for the fifth year in a row, NTU’s research is known and respected across all corners of the globe.

Belize Music Agency offering free music classes | LoveFM

Johnelle McKenzie, Author at LoveFM notes, The participants in the next story won’t be carrying 2 knapsacks but they will have instruments. 

James Sanker, Belize Music Agency

Learning to play music can be a very costly venture.  However, James Sanker of Belize Music Agency is holding a free six-month musical training for children. Love News spoke with Sanker about the initiative

James Sanker, Belize Music Agency: “It’s call the Southside music program. The aim of it is to engage youths from the Southside in learning music. I taught summer would have been too short to get the results I would have liked and so it’s a six month program, it’s free and I have four music classes each week, guitar on Monday on Tuesday we have keyboard, on Wednesday we have vocals and drumming on Friday, we will be teaching Kriol drums and acoustic drum sets. Right now we have enrolled in the class we were aiming at having ten students per class we have a little bit more than that but with some other assistance I think I might be able to take on more people in the course so if you would still like to bring your kid starting from 12-18 to come there is still room that we will be able to accept people.”

Interested persons can call 632-3224 or 205-6294 for more information. Sanker said that the children will participate in a musical performance at the end of the training.
