source: Kane B 2016年5月27日 In this series, I will introduce various philosophical theories of colour. However, in order to understand the philosophy of colour, it is important to have at least a basic grasp of colour science. This video briefly outlines: the physical causes of colour; the structure of the retina; two central theories of colour perception, the trichromatic theory and the opponent-process theory; and the phenomenon of colour constancy. The majority of this video was drawn from "Color for Philosophers" by C.L. Hardin and "Neuroscience: Exploring the Brain" by Bear, Connors, and Paradiso, chapter 9 ("The Eye").

Milk is abundant at our local grocery store in the form of dairy products and infant formulas. This ubiquity of homogenized milk in our modern environment has the potential for the general public, and even researchers, to think of milk one dimensionally. Milk is not just food, however, but is also medicine and signal. Hundreds, possibly thousands, of other milk “bioactives” affect the infant. Professor Hinde presents emerging research that addresses the magnitude, sources, and consequences of inter-individual variation in mother’s milk including that the “recipe” for milk can be different for sons and daughters.

Royal Society GlaxoSmithKline Lecture 2016 by Professor Andrew Hattersley FMedSci FRS.
Diabetes affects over 4 million people in the UK but there are still many uncertainties about the causes and best treatment approaches for this common condition.
Professor Andrew Hattersley FRS will show how, for patients with pure genetic diabetes, defining the specific causes of a patient’s diabetes has resulted in dramatic improvements in their treatment. These findings have changed the management of patients born with diabetes or with strongly familial diabetes throughout the world and have led to molecular genetic testing becoming a first line clinical investigation. The fundamental principle of this Precision Medicine approach is that defining discrete aetiological subgroups of patients within a broader clinical diagnosis can improve clinical care for patients.
The next challenge is to use 'Precision Diabetes' to define different subtypes of the common forms of diabetes (Type 1 and Type 2) and to use this information to improve care. Early work suggests that there are genuine differences between patients with the same clinical diagnosis and these do alter the response to diabetes treatments.

Inside the Tech Start-up Bubble with Dan Lyons. What is the truth behind the Silicon Valley hype? Is it solid business or a hot-air bubble full of ‘wantrepeneurs’? Former technology editor at Newsweek and co-producer and writer of HBO’s Silicon Valley, Dan Lyons is one of the lone dissenting voices amongst the tech hype. He visits the RSA to reveal the dysfunctional culture that prevails in a world flush with money and devoid of experience. He provides a unique analysis of the sometimes bizarre start-up world; a de facto conspiracy between those who start companies and those who fund them.

The word parenting, as a verb, has only been around since 1958. Developmental psychologist Alison Gopnik examines when caregiving became the art of hovering, and the pitfalls and anxiety of trying to shape children instead of raise them. Gopnik's latest book is "The Gardener and the Carpenter: What the New Science of Child Development Tells Us about the Relationship Between Parents and Children" (http://goo.gl/3E0Ti2).

Transcript - Once we started thinking about the role that parents and children play in human evolution one of the things that became very apparent is that that role was very different from the prevailing role in our current culture about parents. So in our current culture there's something called parenting and that very words, that verb only first appeared in 1958. And if you look at the Google Ngram it's sores up in the 1970s. And that word comes with a picture and that picture is that what caregivers do is shape or mole the child to come out a particular way. So your job as a caregiver is to do a bunch of things, acquire a bunch of expertise that will lead to a particular kind of child, which will lead to a particular kind of adult. And then somehow if you just get the right expertise you can create a better child who will create a better adult. Now exactly what that better means is a little unclear. I think parents whisper under their breath better like better than the kid next-door. But anyway, there's some picture, which I think of as the carpenter picture of caregiving, which is that you're going to shape this child into a particular kind of adult. And that picture, which goes with that word parenting, really is very recent. It really only developed at the end of the 20th century. So that picture is the picture that's become prominent in our discussions about caregiving, but it's very, very different from the picture that comes from thinking about caregiving in an evolutionary context and it's also very differently from the picture that comes from the studies that we've done in my life and others about how children actually learn.

Vernon Neppe, MD, PhD, FRSSAf, is a neuropsychiatrist and head of the Pacific Neuropsychiatric Institute in Seattle. He is a former president of the South African Society for Psychical Research. He is author of Déjà Vu Revisited, Déjà Vu: A Second Look, Déjà Vu: Glossary and Library, Cry the Beloved Mind: A Voyage of Hope, Reality Begins with Consciousness: A Paradigm Shift that Works (written with physicist Edward Close), and Innovative Psychopharmacotherapy. His professional publications number over 700. Dr Neppe has amplified many of his concepts in two of the websites linked with his work. On www.Brainvoyage.com, his books are amplified. www.VernonNeppe.org is his gateway and includes more information on the Neppe-Close model of the Triadic Distinction Vortical Paradigm.
Here, Dr. Neppe defines déjà vu as an “as if” experience that is accompanied by the impression of inappropriateness. He notes that there are dozens of different kinds of déjà vu experience that he divides into four different types. Associative déjà vu is the most common type and is non-pathological. As the name suggests, is based on psychological associations. Two pathological types of déjà vu are related either to epilepsy or to psychosis. The fourth type is based upon subjective paranormal experience. Neppe distinguishes between déjà vu and precognitive experience.
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 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.

We are all familiar with the notion that time passes, but what does it actually mean? Could temporal passage just be an illusion? In this talk, Simon Prosser argues that the passage of time is indeed illusory. He begins by outlining some philosophical theories of temporal passage (the A theory of time - including presentism and the growing block), along with a class of theories according to which time does not objectively pass (the B theory of time - what's called eternalism or the block universe). Dr. Prosser then goes over traditional problems for the notion of passage, including McTaggart's argument, the issue of the rate of passage (i.e. how fast time passes), and the argument that passage is incompatible with modern physics (in particular, with Einstein's special theory of relativity). He then goes on to discuss his own argument that, despite appearances to the contrary, it's not actually possible to experience time passing. But because the best reason for thinking that time passes is our experience of it, we no longer have any good reason for thinking that it actually passes. If this is right, then it is an important project for philosophers and psychologists to explain why it seems to us that time passes.
"What then is time? If no one asks me, I know what it is. If I wish to explain it to him who asks, I do not know." Augustine
