Human Evolution

Another mesmerizing article shared by @Kirti.
I'm taking a print out and putting it along with my most treasured books in my book-shelf!


Not providing you with extracts as yet. Plan to re-read it a few times.
You must read the entire article to experience the knowledge.


Goes a long way to prove the impact of parenting and environment on children and human development as a whole!

Science. Knowledge. Ignorance. Failure. Conversations.

One of the best articles I've read in recent times. Fascinating.  Hat tip to @Kirti

============================================

Excerpts:

(Twentieth-century science philosopher Thomas Kuhn, for instance, defined normal science as the kind of research in which “everything but the most esoteric detail of the result is known in advance.”)

The lesson is that not all data is created equal in our mind’s eye: When it comes to interpreting our experiments, we see what we want to see and disregard the rest.

Too often, we assume that a failed experiment is a wasted effort. But not all anomalies are useless. Here’s how to make the most of them. —J.L.

1. Check Your Assumptions: Ask yourself why this result feels like a failure. What theory does it contradict? Maybe the hypothesis failed, not the experiment.
2. Seek Out the Ignorant: Talk to people who are unfamiliar with your experiment. Explaining your work in simple terms may help you see it in a new light.
3. Encourage Diversity: If everyone working on a problem speaks the same language, then everyone has the same set of assumptions.
4. Beware of Failure-Blindness: It’s normal to filter out information that contradicts our preconceptions. The only way to avoid that bias is to be aware of it.

Modern science is populated by expert insiders, schooled in narrow disciplines. Researchers have all studied the same thick textbooks, which make the world of fact seem settled. This led Kuhn, the philosopher of science, to argue that the only scientists capable of acknowledging the anomalies — and thus shifting paradigms and starting revolutions — are “either very young or very new to the field.” In other words, they are classic outsiders, naive and untenured. They aren’t inhibited from noticing the failures that point toward new possibilities.

While the scientific process is typically seen as a lonely pursuit — researchers solve problems by themselves — Dunbar found that most new scientific ideas emerged from lab meetings, those weekly sessions in which people publicly present their data. Interestingly, the most important element of the lab meeting wasn’t the presentation — it was the debate that followed. Dunbar observed that the skeptical (and sometimes heated) questions asked during a group session frequently triggered breakthroughs, as the scientists were forced to reconsider data they’d previously ignored. The new theory was a product of spontaneous conversation, not solitude; a single bracing query was enough to turn scientists into temporary outsiders, able to look anew at their own work

But not every lab meeting was equally effective. Dunbar tells the story of two labs that both ran into the same experimental problem: The proteins they were trying to measure were sticking to a filter, making it impossible to analyze the data. “One of the labs was full of people from different backgrounds,” Dunbar says. “They had biochemists and molecular biologists and geneticists and students in medical school.” The other lab, in contrast, was made up of E. coli experts. “They knew more about E. coli than anyone else, but that was what they knew,” he says. Dunbar watched how each of these labs dealt with their protein problem. The E. coli group took a brute-force approach, spending several weeks methodically testing various fixes. “It was extremely inefficient,” Dunbar says. “They eventually solved it, but they wasted a lot of valuable time.”

The diverse lab, in contrast, mulled the problem at a group meeting. None of the scientists were protein experts, so they began a wide-ranging discussion of possible solutions. At first, the conversation seemed rather useless. But then, as the chemists traded ideas with the biologists and the biologists bounced ideas off the med students, potential answers began to emerge. “After another 10 minutes of talking, the protein problem was solved,” Dunbar says. “They made it look easy.”

When Dunbar reviewed the transcripts of the meeting, he found that the intellectual mix generated a distinct type of interaction in which the scientists were forced to rely on metaphors and analogies to express themselves. (That’s because, unlike the E. coli group, the second lab lacked a specialized language that everyone could understand.) These abstractions proved essential for problem-solving, as they encouraged the scientists to reconsider their assumptions. Having to explain the problem to someone else forced them to think, if only for a moment, like an intellectual on the margins, filled with self-skepticism.

Hmmm!??

The UNIfied UNIverse

I was running through a pocket book on Vivekananda’s approach to meditation today on the way to office. The book states that Vivekananda spoke about the fact that the microcosm and the macrocosm are the same, after one of his enlightening experiences. He said; at the atomic level everything in the universe is the same - they work on the same principles. I took my eyes off the book and went back to something else that I had stumbled upon earlier - a TV programme (The elegant universe) that mentioned Einstein’s unsuccessful quest for the unified theory, which – now - according to the string theory is highly unlikely as, for example, gravity doesn’t apparently work at the sub-atomic level. The forces in the micro-microcosm are supposedly different from what we experience at our level. I feel the urge to explore this matter in detail….

Discovering the Universe!

Saw this prg. on TV - Discovery- last weekend! It was absolutely Fantastic! Search for "Elegant Universe" + "Einstein's Dream" on Google and log into Discovery Online...I'll try and post more links later...no time to value-add now.. :(

Okay! Here's an update - I bought the book "The elegant universe" by Brian Greene the day before! It is all about man's quest to unify the theory of gravity, electromagnetism and the nuclear forces into one theory dubbed as the theory of everything/string theory/M theory....interesting stuff if you love physics/want to know more about our universe and where it began...
