Eve Ensler asks “What is security?”

In this TED talk, Eve Ensler (who wrote “The Vagina Monologues“) addresses the question, “What is security?”

According to Ensler, security is elusive and impossible, and that’s the good news, “unless your whole life is about being secure.” If you’re one of those people who obsess about security, you will become a cultural and intellectual recluse. You will become a frozen and numbed to the possibility of change/growth and you will perceive enemies to be everywhere. All you’ll have time for is to worry about protecting yourself.

The talk then moves to engaging stories about women who have created real versions of security. Real security is “hungering for connection rather than power.”

Bacteria that talk to each other

Bonnie Bassler, who teaches molecular biology at Princeton, explains that bacteria don’t just grow and divide, grow and divide. They speak to each other and with other species of bacteria through their chemicals.

Bassler studies how bacteria use chemical signals to act as coordinated social units. In this delightful TED talk, Bassler discusses how her research group has studied the manner in which bacteria talk to each other. They make chemical “words” to enable group activities (such as triggering the timing for effective virulence attacks), sensing each other through their “quorum-sensing molecules.” They can also sense the difference between themselves and other bacteria.

Note that each of us is 99% bacterial. Our human body consists of about one trillion of “our own” cells, but ten trillion bacteria. We have about 30,000 of “our own” genes, but we carry about 100 times more bacterial DNA than human DNA. Bacteria live as “mutualists” with us. They help us digest our food, make our vitamins, protects us from other pathogens and help us survive in numerous other ways.

Rather than using antibiotics to kill bacteria (which inevitably selects for more virulent strains), Bassler suggests that a better understanding of the communications schemes used by bacteria is allowing scientists to develop potent new medicines.

This is an upbeat and informative talk regarding a most ancient form of life.

The importance of play for adults

The importance of play for adults

In a recent talk at TED, psychiatrist Stuart Brown talked about the vital importance of play. Brown opened his talk by showing an incredible series of photographs demonstrating that a huge hungry polar bear can be seduced into playing with dogs rather than eating them. Like a polar bear, play induces an “altered state” in humans. Play is a great leveler: great differences in power can be overridden by play. In fact, the absence of play is dangerous, as demonstrated by the case histories of mass murderers.

Brown describes various kinds of play, including body play (e.g., jumping), object play (manipulating objects), social play, rough-and-tumble play, ritual play and imaginative play (storytelling). These activities simply make us feel better. They are purposeless. In fact, if the purpose is more important than the act of doing these things, they are not “play.” As I listened to this list, I was wondering whether sexual play is of the same importance as the other types of play.

The study of play is still in its infancy. Historically, this has not been a well-funded area of scientific investigation. Nonetheless, the evidence we already have suggests that play is important for developing cognitively, emotionally and developmentally. We already know that “nothing lights up the brain like play.” In fact, the ability to trust is learned through vocal, facial and gestural play signals. As Brown indicates, humans are perhaps the most neotonous species, suggesting a special need for humans to engage in play, whether they are infants or adults.

Various animal studies have shown that her mental effects of preventing an animal from playing. Thus, it seems that play is important for survival. In fact, life without play seems to lead inexorably to depression. When we look back in our history to determine what sorts of activities energized us when we were youngsters, we might deal with see that we have strayed from those things that gave us the pleasure of play. When we explore our personal history, we might find that we are mismatched in terms of career or other activities.

Brown encourages the audience that they should not set aside time to play. Rather, they (including adults) should infuse every moment of their lives with play. He argues that play is just important for humans as is asleep and dreaming.

How to follow the Bible literally.

Writer A. J. Jacobs embarked upon a one-year attempt to follow all of the rules in the Bible. To do so, he first wrote down every rule he spotted in the Bible (he came up with 700). Following those rules was difficult, however, especially when he didn’t quite understand them. For instance, where are the “corners” of one’s beard?

Though his talk is often humorous, Jacobs reveals some serious epiphanies he had along the way. For instance, he found that his behavior sometimes changed his thoughts (he found that visiting sick people made him more compassionate rather than the other way around). He learned to give thanks for the hundreds of things that went right every day, rather than focusing on the few things that went wrong. He learned to have reverence for many aspects of his life, even though he remained an agnostic through the whole experience. He also learned that he shouldn’t completely dismiss that which is irrational, and we all have irrational aspects of our lives (is blowing out birthday candles on a cake rational?).

You’ll enjoy Jacobs’ understated delivery and his respect for those who are different. His talk is well worth a viewing, no matter where you fall on the belief continuum.

Check out these high school kids playing Shostakovich

TED has some incredible offerings these days. Here is one that about knocked me out of my chair. Turn up your computer sound and sit back for 20 minutes. Here’s the description from TED.

Gustavo Dudamel and the young members of the orchestra, many born into poverty, had had their lives transformed by a national music teaching program built by TED Prize Winner Jose Antonio Abreu. The Teresa Carreño Youth Orchestra contains the best high school musicians from Venezuela’s life-changing music program, El Sistema. Led here by Gustavo Dudamel, they play Shostakovich’s Symphony No. 10, 2nd movement, and Arturo Márquez’ Danzón No. 2.

An appeal to practical moral wisdom

An appeal to practical moral wisdom

Barry Schwartz recently delivered a sensational 20-minute talk on the importance of practical wisdom. He began his talk by describing the obvious: we now live in a highly dysfunctional rule-bound society. What should we do about it? We need to make sure that kindness, care and empathy are a part of every job, whether or not these responsibilities are contained in the official job description. All of us need to have both moral will and moral skill, the two essential components of Aristotle’s conception of “moral wisdom.” Luckily for us, we now have a President who is willing to take the risk of reminding Americans of their duties to pursue moral wisdom.

Schwartz deserved that standing ovation he received after delivering this talk at TED. Much of his talk concerned our obsessions with rules. Yes, rules are oftentimes hopeful. They often help us avoid the mistakes of the past. On the other hand, wise people know that they sometimes need to improvise. They know when to break the rules in order to remedy situations. They know that they are never excused from being kind and decent, regardless of the “rules.” Schwartz gives several salient examples, an especially good one involving a janitor. Wise people know that they need to use rules not simply to “follow the rules” but to serve the needs of other people.

More on the corn ethanol fiasco

Corn ethanol is a terribly costly and damaging joke that has been inflicted on us by politicians looking for something that looks like a fix, rather than doing the much harder work to find real solutions to our energy problems.   I’ve posted on corn ethanol before, and it’s now time to pull down the tent [...]

Steven Strogatz discusses how things in nature tend to sync up all by themselves.

Stephen Strogatz is a mathematician who has studied synchrony in nature. Synchrony is the “spontaneous tendency of separate entities to act as a unit.” Strogatz finds synchrony “everywhere” in nature. He stresses that you don’t need to be smart to synchronize, nor do you need to have a brain or even be alive. I learned [...]

Meet the the man who first identified “flow”

I’ve often heard about “flow,” but never from the man who was personally responsible for developing the theory:  Mihaly Csikszentmihalyi (pronounced “cheeks sent me high”).
For the first part of his lecture, you’ll hear that beyond the poverty level, money and material things don’t increase happiness.
From there, Csikszentmihalyi describes a state that brings great happiness.  [...]
