Avner Ash and Robert Gross: "Summing it Up" | Talks at Google

source: Talks at Google    2016年9月26日
Summing it Up: From One Plus One to Modern Number Theory
Summing It Up, published in May this year, is a book about number theory, for the proverbial "general audience", concentrating on sums and series. It begins with very simple questions about whole numbers, such as "what is the sum of the first n k-th powers" and "how many ways can you break up a positive whole number into whole number parts" and shows how such questions lead naturally to the use of calculus and infinite series. The more advanced methods, besides providing new insight into the original questions, lead to further ideas and new questions. The book ends by discussing "modular forms", which are certain infinite series that were crucial in the proof of Fermat's Last Theorem.
In this talk, the authors will attempt to explain what is number theory, through examples, notably Bernoulli numbers. They will discuss the question "why might (should?) a normal person be interested in number theory?" (Spoiler alert: there is no final answer to that question.)
The authors are both professors of mathematics in Boston College. They both do research in number theory and they both have strong interests in books of all sorts, reading them as well as writing them.

Dementia: Catching the memory thief

source: Cambridge University    2016年9月21日
It's over a hundred years since the first case of Alzheimer’s disease was diagnosed. Since then we’ve learned a great deal about the protein ‘tangles’ and ‘plaques’ that cause the disease. How close are we to having effective treatments – and could we even prevent dementia from occurring in the first place? Researchers at the University of Cambridge describe some of the progress now being made against this devastating disease.

The Great Time War - The Reality of Time

source: Philosophical Overdose     2016年9月18日
Over two millennia ago Heraclitus declared that all is flowing: you can’t step in the same river twice. Parmenides, on the other hand, thought that time is an illusion and all is fixed and permanent. He would fare well in the modern age where spacetime has won the intellectual day. Or has it? A new challenge is reigniting the Heraclitian view of the cosmos, and attempting to put the seconds, minutes and hours back into the arrow of time.
This is an episode from the ABC Radio Natural show the Philosopher's Zone. The guests are Kristie Miller, Roberto Unger, Craig Callender, and Huw Price. http://www.abc.net.au/radionational/

Build Mental Models to Enhance Your Focus | Charles Duhigg

source: Big Think    2016年9月15日
According to Pulitzer winner Charles Duhigg, the art of focus is training your mind to know what it can safely ignore. Duhigg's latest book is "Smarter Faster Better: The Secrets of Being Productive in Life and Business" (http://goo.gl/gNhDR6).

Transcript - Nowadays it’s incredibly hard to stay focused. There’s so many distractions around us at any given moment. Your pocket vibrates at any given moment because you’re getting ten new emails and on social media there’s all these new notifications and the phone is ringing and your kids need help and your colleagues are coming up because you are working in an open office plan and they’re asking you to chime in on some memo. Maintaining focus nowadays is harder than ever before. But it’s way more critical too. One of the things that we know about the most productive people and the most productive companies is that they create ways to enhance their focus. They manage their mind in such a way that they’re able to focus on what’s important and ignore distractions much better. And the way that they do this is by what’s known as building mental models.
Essentially telling themselves stories about what they expect to see, engaging in this kind of inner dialogue about what they think should be happening that allows their brain almost subconsciously to figure out what to pay attention to and what to ignore. One of my favorite examples of this is a big study that was done of nurses in NICUs. Some researchers from a group named Client Associates went into some hospitals because they wanted to figure out why some nurses were so good at paying attention to the right things whereas others got distracted by all the noise and bustle around them. And what they found is that the best nurses in NICUs which is the neonatal intensive care unit who were handling these babies, the nurses who were almost had a sixth sense or an ESP about figuring out which babies were sick and were getting sicker were the ones who were constantly telling themselves stories about what they expected to see as they were walking around the hospital. So one of my favorite interviews from this study was with a nurse named Darlene. And Darlene said that what she would do is that she always was keeping a picture in her brain of what she thought the perfect baby should look like. And so she would walk through the unit and she would notice when babies didn’t kind of match that picture in her brain, right. And they would match – they would mismatch that picture in kind of odd ways. Read full transcript here: https://goo.gl/dRTTZW.

Philosophy of Mathematics by Kane B

source: Kane B     2013年4月6日
This is a brief introduction to the modern mathematical views on infinity. I've tried to make it accessible to everybody; you don't need any mathematical knowledge to follow it. I discuss the Hilbert Hotel thought experiment, some very basic set theory, one-to-one correspondence, and Cantor's Diagonal Argument.
I mention a couple times in the video, e.g. at 9:02, that we can take things away from infinity, and still have infinity. This is true, unless to take infinity from infinity. Infinity minus infinity is undefined. It's easy to see why. Consider the hotel again. Suppose it's full, and now consider what happens when: (1) everybody in the even-numbered rooms leave, but everybody in the odd-numbered rooms stay; (2) everybody but those in the first million rooms leave; (3) everybody but the person in the first room leaves. In each of these cases, an infinite number of people have left, but how many remain? In the first case, infinity -- infinity = infinity. In the second, infinity -- infinity = one million. In the third, infinity -- infinity = one.
Re the points around 27:30: the hypothesis that the cardinality of the reals is aleph-one (that is, that there is no infinity in between the naturals or the reals) is known as the "continuum hypothesis". It has been shown that, on the axioms of standard set theory, it's impossible for the continuum hypothesis to be either proved or disproved. It's completely independent of the standard axioms.

Protection from Gender Violence as a Civil Right

source: Harvard University     2016年9月19日
In this seminar, the recent efforts by the Department of Education’s Office of Civil Rights (OCR) to enforce Title IX policy are considered in the broader context of unsuccessful attempts to establish protection of sexual violence as a civil right in the United States. OCR enforcement has stimulated both praise for its bold determination to address an epidemic of sexual violence on college campuses and criticism for its capacious exercise of administrative power. Bumiller reframes this debate by considering how these regulatory measures are a new chapter in a varied and complex story about the effectiveness of public enforcement of civil rights statutes through the combination of administrative and judicial action. Her work questions whether over reliance on public agency enforcement potentially weakens the participatory and democratic effects of private action. She also examines how current federal regulations regarding Title IX continue a pattern that over emphasizes criminal justice priorities.

Shamanic Practices with Nicki Scully

source: New Thinking Allowed    2016年4月18日
Nicki Scully has been teaching healing, shamanic arts, and the Egyptian mysteries since 1983. She is coauthor, with Normandi Ellis, of The Union of Isis and Thoth: Magic and Initiatory Practices of Ancient Egypt. Her other books include Planetary Healing: Spirit Medicine for Global Transformation; Alchemical Healing; Power Animal Meditations: Shamanic Journeys with Your Spirit Allies; The Anubis Oracle: A Journey into the Shamanic Mysteries of Egypt; and Shamanic Mysteries of Egypt: Awakening the Healing Power of the Heart.
Here she describes the shamanic path as generally starting with an illness that the shaman to be must learn to heal. On occasions, this condition may be misdiagnosed by the medical profession as a form of mental illness. She points out that, while some may not associate the high culture of ancient Egypt with shamanism, the Egyptian gods represent the various animal powers. The Egyptian temple initiation rites involve shamanic instructions concerning travel between the worlds. She notes that it is possible to weave together different shamanic traditions like the plaits of a braid.

New Thinking Allowed host, Jeffrey Mishlove, PhD, is author of The Roots of Consciousness, Psi Development Systems, and The PK Man. Between 1986 and 2002 he hosted and co-produced the original Thinking Allowed public television series. He is the recipient of the only doctoral diploma in "parapsychology" ever awarded by an accredited university (University of California, Berkeley, 1980). He teaches parapsychology for ministers in training with the Centers for Spiritual Living through the Holmes Institute. He has served as vice-president of the Association for Humanistic Psychology, and is the recipient of its Pathfinder Award for outstanding contributions to the field of human consciousness. He is also past-president of the non-profit Intuition Network, an organization dedicated to creating a world in which all people are encouraged to cultivate and apply their inner, intuitive abilities.
