  • Less is more: Why our brains struggle to subtract

    6:20

    When solving problems, humans tend to think about adding something before they think of taking something away - even when subtracting is the better solution. Experiments show that this newly discovered psychological phenomenon applies across a range of situations from improving a physical design to solving an abstract puzzle.

  • Happy Brain: How to Overcome Our Neural Predispositions to Suffering | Amit Sood, MD | TEDxUNI

    18:07

    Twenty years ago, Dr. Amit Sood, a Professor of Medicine at Mayo Clinic, came to the U.S. thinking he was coming to the Disneyland of the world. He expected everyone here to be very happy. What he saw surprised and shocked him. In this funny, fast-moving, and deeply insightful talk, Dr. Sood shares his journey over two decades and across two continents, finding a way to help us outsmart our neural predispositions to suffering. In the process, he takes us on a back-stage tour of the human brain and outlines the gist of a structured program he is taking globally to decrease stress and improve focus, resilience, and happiness.

    Amit Sood, MD, is Professor of Medicine at Mayo Clinic and Director of Mayo's Complementary and Integrative Medicine program. He is the author of The Mayo Clinic Guide to Stress-Free Living and The Mayo Clinic Guide to Happiness. He is one of the most sought-after speakers at Mayo. He has received several NIH and foundation awards to test and implement integrative and mind-body approaches within medicine. Dr. Sood received the 2010 Distinguished Service Award, the 2010 Innovator of the Year Award, and the 2013 Outstanding Physician Award from Mayo Clinic.

  • After watching this, your brain will not be the same | Lara Boyd | TEDxVancouver

    14:25

    In a classic research-based TEDx Talk, Dr. Lara Boyd describes how neuroplasticity gives you the power to shape the brain you want. Recorded at TEDxVancouver at Rogers Arena on November 14, 2015.

    YouTube Tags: brain science, brain, stroke, neuroplasticity, science, motor learning, identity, TED, TEDxVancouver, TEDxVancouver 2015, Vancouver, TEDx, Rogers Arena, Vancouver speakers, Vancouver conference, ideas worth spreading, great idea,

    Our knowledge of the brain is evolving at a breathtaking pace, and Dr. Lara Boyd is positioned at the cutting edge of these discoveries. In 2006, she was recruited by the University of British Columbia to become the Canada Research Chair in Neurobiology and Motor Learning. Since that time she has established the Brain Behaviour Lab, recruited and trained over 40 graduate students, published more than 80 papers and been awarded over $5 million in funding.

    Dr. Boyd’s efforts are leading to the development of novel, and more effective, therapeutics for individuals with brain damage, but they are also shedding light on broader applications. By learning new concepts, taking advantage of opportunities, and participating in new activities, you are physically changing who you are, and opening up a world of endless possibility.

  • The Death Of Arithmetic: How Indian Eyes Make Maths Education Simpler & Faster | Jonathan J Crabtree

    1:8:08

    Historians of Indian mathematics have long discussed how the concept of zero, positives, negatives and the laws of sign were documented in the early 7th Century. However, new research reveals an incomplete understanding of India’s zero in the Medieval Arabic world. This meant the role of zero as a placeholder was transmitted to Renaissance Europe, yet the more profound role of zero as a number, defined as the sum of equal positives and negatives, was not. As a result, neither negatives nor zero were involved in early and subsequent developments in Algebra and erroneous rules on Integer ordering emerged.

    Today, this incomplete understanding of zero and negative numbers persists in typical elementary school classes. Alongside historical observations, the author, Jonathan J Crabtree calls for a more cohesive curriculum, constructed around India’s original understanding of zero that better integrates the laws of mathematics, physics and common sense.

  • The Physics and Philosophy of Time - with Carlo Rovelli

    54:54

    From Boltzmann to quantum theory, from Einstein to loop quantum gravity, our understanding of time has been undergoing radical transformations. Carlo Rovelli brings together physics, philosophy and art to unravel the mystery of time.
    Subscribe for regular science videos:

    Carlo's book The Order of Time is available now -

    Watch the Q&A:

    Time is a mystery that does not cease to puzzle us. Philosophers, artists and poets have long explored its meaning while scientists have found that its structure is different from the simple intuition we have of it. Time flows at a different speed in different places, the past and the future differ far less than we might think, and the very notion of the present evaporates in the vast universe.

    Carlo Rovelli is a theoretical physicist who has made significant contributions to the physics of space and time. He has worked in Italy and the US, and is currently directing the quantum gravity research group of the Centre de physique théorique in Marseille, France. His books 'Seven Brief Lessons on Physics' and 'Reality Is Not What It Seems' are international bestsellers translated into forty-one languages.

    This talk and Q&A was filmed in the Ri on 30 April 2018.

  • Math isnt hard, its a language | Randy Palisoc | TEDxManhattanBeach

    8:55

    This talk was given at a local TEDx event, produced independently of the TED Conferences. Is 26% proficiency in math acceptable to you? That's the question teacher and Synergy Academies Founder Dr. Randy Palisoc asks the TEDxManhattanBeach audience. With only 26% of U.S. twelfth graders proficient in mathematics, Randy shares his solution: teach math as a language. Putting words back into math lessons enables even the youngest school-age minds to grasp complex concepts, such as fractions, that are traditionally thought of as abstract and difficult to understand. In his stunningly simple and effective approach, math no longer creates problems for kids but solves them.

    Randy Palisoc is a passionate educator, known for making math easy. A founder of the five-time national award winning Synergy Academies, Randy is proud to identify Synergy as an “in spite of” school. In spite of the fact that its students were disadvantaged and in spite of the fact that it did not have its own facility and had to pack up its classrooms every single week, his school was the first and only elementary school in South Los Angeles to ever win the National Blue Ribbon Award, and was named the #1 Urban Elementary School in America in 2013.

    Seeking a broader impact, Randy left Synergy this year to start Ironbox Education. One of the ways he believes we can dramatically improve America’s schools is by doing a better job teaching math to our students in a way that makes sense to them. Randy believes implementing a few changes in the way we approach math will give students the confidence and thinking skills to be more competitive in a global economy.

  • Why Did I Eat That? Obesity and the Neuroscience of Food Craving

    59:34

    Each month The Brain & Behavior Research Foundation hosts a Meet the Scientist Webinar featuring a researcher discussing the latest findings related to mental illness. In October, 2020, the Foundation featured Dr. Carrie Ferrario of the University of Michigan Medical School.


    Description: While urges to eat are regulated by hunger, our need for energy, and our sense of satiety or fullness, they’re also strongly influenced by sights, sounds, and smells associated with food. Dr. Ferrario’s research, which draws on concepts in addiction and learning, explores the neurobiological mechanisms of cue-triggered food craving and how these are influenced by consumption of sugary, fatty, “junk-food” diets and individual susceptibility to obesity. She will discuss how alterations in excitatory nerve-cell transmission within the brain's reward pathway influences food craving, and how these alterations relate to eating behaviors.

  • Is Social Media Hurting Your Mental Health? | Bailey Parnell | TEDxRyersonU

    14:45

    Scrolling through our social media feeds feels like a harmless part of our daily lives. But is it actually as harmless at seems? According to social media expert Bailey Parnell, our growing and unchecked obsession with social media has unintended long term consequences on our mental health. As social media continues to become part of the fabric of modern life – the “digital layer” – abstinence is becoming less of an option. Bailey think it’s high time we learned to practice safe social before it’s too late. What are the common triggers? How are they affecting you over time? How can you create a more positive experience online? Bailey covers this and more in “Is Social Media Hurting Your Mental Health?”

    Bailey Parnell was recently named one of Canada's Top 100 Most Powerful Women. She is an award-winning digital marketer, public speaker and businesswoman with a talent for helping people tell better stories. Her work and expertise have been featured on CBC, CTV & in other local Toronto media. Bailey recently founded SkillsCamp, a soft skills training company where they help people develop the essential skills needed for professional success. She also currently works in digital marketing at Ryerson University.

    Bailey is a frequent public speaker having spoken to more than 10 thousand people. She primarily speaks about social media, personal branding, and media and mental health. She guest lectured her first MBA class at 21-years-old and has been the youngest speaker as multiple academic conferences. She is currently pursuing her Masters in Communication and Culture with a research focus on social media and mental health, and holds an honours BA from the RTA School of Media at Ryerson.

  • Secrets of Subtraction: Donut Holes, Lego and Bruce Springsteen with Leidy Klotz

    1:11:09

    Source:


    Leidy Klotz is the Copenhaver Associate Professor of Architecture, Civil and Environmental Engineering at the University of Virginia. His research fills in underexplored overlaps between engineering and behavioral science, in pursuit of more sustainable environmental systems. He has published over 70 peer-reviewed articles in venues that include top academic journals in built environment engineering, engineering education, and design, as well as imprints of both Science and Nature.
    We explored the rarity of subtraction from our lives and the fact that we tend to add things much more than we remove things. Granted, we’ve been builders of things since the dawn of civilization, but when is enough, enough? Leidy suggested we begin any initiative by subtracting before we start adding.  
    We traced the concept from Lao Tzu through DaVinci through Kurt Lewin and right up into today’s literature with Marie Kondo and Tim Ferriss. But Leidy’s thoughts are truly fresh because he is adding to this historical narrative with scientific data. He offered us fresh ways to think about this uphill battle with our natural desires. 
    We also discussed Leidy’s view of the Planetary Tipping Point: where our very fixed-resource planet gets maxed out by humans with an unlimited desire for more. And we were pleased to talk about Kurt Lewin and his force-field analysis and, as you might expect, we enthusiastically discussed Bruce Springsteen as a prolific and gifted writer.

    Interview Quotes
    (8:10) we're doing these mental searches for solutions, and our mind goes to additive solutions before it goes to subtractive ones. 
    (12:01) as people are trying to change things from how they are to how they want them to be, we systematically think of adding first and then, only subsequently or with effort or with reminders, think of subtraction
    (35:15) so often we kind of come to a problem and don't actually spend time defining what the what the problem is, right
    (9:51)  My favorite is Lao Tzu, even farther back talking about, to gain wisdom, you have to subtract something every day.

  • Conditions of Possibility: Slavoj Žižek Part II

    Stress. It makes your heart pound, your breathing quicken and your forehead sweat. But while stress has been made into a public health enemy, new research suggests that stress may only be bad for you if you believe that to be the case. Psychologist Kelly McGonigal urges us to see stress as a positive, and introduces us to an unsung mechanism for stress reduction: reaching out to others.

  • Anisometropia: Can’t Focus? What Happens When Your Eyes Don’t Have Equal Sight

    2:13

    Anisometropia is an eye condition where someone’s eyes have unequal refractive power (the degree where the eye differentiates light). This condition hurts your eye’s ability to focus and can cause severe headaches. Evan Kaufman, MD, explains this condition and how UVA treats patients with anisometropia.

    For more information visit

    In Evan Kaufman's words:
    With anisometropia, one eye might see perfectly while the other eye doesn’t see well at all. Since eyes work together to see, if one eye is in focus and the other eye is not, a discrepancy occurs in the brain. The brain then tells the eye with the poorer vision to shut down. This will become amblyopic (decreased eyeslight), or you get a really big headache. We see a lot of strenuous headaches and people that have anisometropia. You can help people with glasses with an uneven prescription. The problem that we have with glasses is the further away you put your refractive surface from the eye, it changes the image that is seen. What I mean by that is if you think about Sherlock Holmes and his magnifying glass, he uses his magnifying glass to find clues or to magnify things. Well, if one eye has a magnifying glass on it, which is your prescription, and the other eye does not have a magnifying glass, then one eye sees things that are really big and the other eye sees things that are normal size. And when you have that size discrepancy, you can get a really bad headache. Contact lenses can sit right on top of the eye. Now, when you deal with magnification, because the contact lens sits right up against the eye, the refractive surface is up against the eye. And whether the prescription’s a minus 10 or a plus 20, because it sits on the eye, the distance that the light has to travel to hit the eye is 0 because it's sitting on the eye. Thus, the magnification or minification is 0, so you have zero-size discrimination when you wear contact lenses in a case of a patient that has anisometropia.

  • Less is More - Strategies to Help Educators Succeed by Subtracting NOT Adding

    28:40

    People naturally feel compelled to solve a problem by adding something to fix it, even when taking something away is the best solution. Educators are even more prone to this as we stockpile ideas, teach tools, and more. In this Wednesday Webinar our Canyon Professional Development experts Cori Araza and Marni Landry introduce how the Less is More mindset can help you get MORE out of your teaching by simplifying things and pursuing LESS.

    Transcript:

    Colors are great!
    So why don’t we use more?

    Well, to many can be… distracting!
    If every element is competing for your attention, your viewers won’t know where to look.

    For example: In our video for iExpressions 3, we’ve got a nice palette of colors.
    But it is only the main character - this guy - who gets his own color.

    This way, viewers have a clear area of focus and won’t get distracted.

  • Four Solutions to a Trivial Problem - Guy Steele Jr.

    1:1:47

    Google Tech Talk, 12/1/2015, Presented by Guy L. Steele Jr.
    ABSTRACT: We present a small but interesting geometrical problem and then examine four different computational approaches to solving it: a classic sequential solution and three different approaches that are amenable to parallel implementation, comparing them to highlight various advantages and disadvantages, including total work required and minimum time to solution. All four solutions are illustrated both pictorially and with working code. We argue that certain approaches work better than others if exploitation of parallelism is to be automated. There will also be at least one joke.
