You can't teach an old dog (or your brain) new tricks: why learning is hard

You can’t teach an old dog (or your brain) new tricks: why learning is hard

VIDEO EXPLAINER/ ARTICLE: The hallmark of intelligence is the ability to learn new tasks. How does the human brain go about the task? The human brain, remarkable as it is, does not go about the task of learning in a very efficient manner. It uses a highly inefficient approach called "Reassociation." We appear to  learn new tasks simply by repeating the original neural activity patterns and swapping their assignments. Although "quick and dirty" it's not the best way to learn. SOURCE: Quanta ...

A "global useless class": the future as seen by Yuval Noah Harari

A “global useless class”: the future as seen by Yuval Noah Harari

VIDEO: Just as the Industrial Revolution created the working class, automation could create a “global useless class,” and the political and social history of the coming decades will revolve around the hopes and fears of this new class. The combination of biotech and I.T. might reach a point where it creates systems and algorithms that understand us better than we understand ourselves. The problem is understanding the “extremely complicated chains of cause and effect” in the world. “Time is accelerating,”. The long term may no longer be defined in centuries or millenniums — but in terms of 20 years. “My fear is that homo sapiens are not just up to it. We have created such a complicated world that we’re no longer able to make sense of what is happening.” SOURCE: The New York Times ...

How to stop someone from talking incessantly

How to stop someone from talking incessantly

INFOGRAPHIC/ VIDEO: Some people love to hear themselves talk so much that, try as you might, you can’t get a word in edgewise. One part art of the problem is that you’re waiting for them to pass the baton to you: they’re simply not going to do it. You don’t have to interrupt them; you can use your body language and shut them up with non-verbal cues . SOURCE: YouTube via Lifehacker ...

To eliminate waste, we need to rediscover thrift

To eliminate waste, we need to rediscover thrift

VIDEO: There's no such thing as throwing something away -- when you toss a used food container, broken toy or old pair of socks into the trash, those things inevitably end up in ever-growing landfills. But we can get smarter about the way we make, and remake, our products. This video shares exciting examples of thrift -- the idea of using and reusing what you need so you don't have to purchase anything new -- as well as advances in material science, like electronics made of nanocellulose and enzymes that can help make plastic infinitely recyclable.

We hardly ever give a thought to the progress bar. This delightful video tells you that there is a lot more behind this humble utility.

A ritual for the later years of life: give away what you have treasured

VIDEO: We use rituals to mark the early stages of our lives, like birthdays and graduations -- but what about our later years? In this meditative talk about looking both backward and forward, Bob Stein proposes a new tradition of giving away your things (and sharing the stories behind them) as you get older, to reflect on your life so far and open the door to whatever comes next.

The population bomb has been defused — Malthus was wrong

VIDEO/ INFOGRAPHIC/ ARTICLE: In order to put the dire prognostications of Malthus and Ehrlich about population growth outstripping the capacity of the Earth to feedits people, inally to rest, an important component is needed - lower fertility rates. Overall world fertility has fallen. There's a strong association between fertility and income levels - once a country passes about $5,000 in per capita annual gross domestic product, it almost never has a high fertility rate. Overpopulation concerns have shifted from global to regional. Countries such as Nigeria, Ethiopia, Tanzania and the Democratic Republic of the Congo still have very high fertility rates.

The brain-body connection is more than we think it is

The brain-body connection is more than we think it is

LONG ARTICLE FOR HARDCORE READERS/ VIDEO: An all pervasive “cerebral mystique” creates a false dichotomy between the brain and the body and ignores bodily influences on our psychology, from chemicals in the blood to bacteria in the gut. What’s outside the body also influences the mind. The environment floods the brain with the equivalent of about 10 megabytes of information per second SOURCE: National Geographic ...
