Mosh pit physics could aid disaster planning - physics-math - 14 February 2013 - New Scientist

Mosh pit physics could aid disaster planning - physics-math - 14 February 2013 - New Scientist | cleav goes webwalking | Scoop.it
An analysis of rock fans dancing reveals how people in a crowd move when emotions are running high, and may help us make buildings easier to evacuate
Cleaven Chia's insight:

Metalheads in mosh pits act like atoms in a gas. That's the conclusion of the first study of the collective motion of people at a rock concert.

The finding could add to the realism of computer-generated crowd scenes in films and games.; More importantly, it could help architects design buildings that ease the flow of chaotic crowds in an emergency.

Remembering Aaron Swartz: David Foster Wallace on the Meaning of Life

Remembering Aaron Swartz: David Foster Wallace on the Meaning of Life | cleav goes webwalking | Scoop.it

Wallace remarks:

"If you worship money and things — if they are where you tap real meaning in life — then you will never have enough. Never feel you have enough. It’s the truth. Worship your own body and beauty and sexual allure and you will always feel ugly, and when time and age start showing, you will die a million deaths before they finally plant you. On one level, we all know this stuff already — it’s been codified as myths, proverbs, clichés, bromides, epigrams, parables: the skeleton of every great story. The trick is keeping the truth up-front in daily consciousness. Worship power — you will feel weak and afraid, and you will need ever more power over others to keep the fear at bay. Worship your intellect, being seen as smart — you will end up feeling stupid, a fraud, always on the verge of being found out. And so on."

The Usefulness of Useless Knowledge | Brain Pickings

The Usefulness of Useless Knowledge | Brain Pickings | cleav goes webwalking | Scoop.it

Maria Popova: "In an age obsessed with practicality, productivity, and efficiency, I frequently worry that we are leaving little room for abstract knowledge and for the kind of curiosity that invites just enough serendipity to allow for the discovery of ideas we didn’t know we were interested in until we are, ideas that we may later transform into new combinations with applications both practical and metaphysical.

 

"In 'The Usefulness of Useless Knowledge', originally published in the October 1939 issue of Harper’s, American educator Abraham Flexner explores this dangerous tendency to forgo pure curiosity in favor of pragmatism — in science, in education, and in human thought at large — to deliver a poignant critique of the motives encouraged in young minds, contrasting those with the drivers that motivated some of history’s most landmark discoveries."

The Presentation Mistake You Don't Know You're Making

The Presentation Mistake You Don't Know You're Making | cleav goes webwalking | Scoop.it

During an interview, your potential new boss asks you to briefly describe your qualifications. At this moment, you have a single objective: be impressive. So you begin to rattle off your list of accomplishments: your degrees from Harvard and Yale, your prestigious internships, your intimate knowledge of essential software and statistical analysis. "Oh," you add. "And I took two semesters of Spanish in college." Not technically an impressive accomplishment, but since the company does a lot of business in Latin America, you figure some Spanish is better than none at all.

 

Or is it?

Open-access deal for particle physics

Open-access deal for particle physics | cleav goes webwalking | Scoop.it

The entire field of particle physics is set to switch to open-access publishing, a milestone in the push to make research results freely available to readers.

 

Particle physics is already a paragon of openness, with most papers posted on the preprint server arXiv. But peer-reviewed versions are still published in subscription journals, and publishers and research consortia at facilities such as the Large Hadron Collider (LHC) have previously had to strike piecemeal deals to free up a few hundred articles.


After six years of negotiation, the Sponsoring Consortium for Open Access Publishing in Particle Physics (SCOAP3) is now close to ensuring that nearly all particle-physics articles — about 7,000 publications last year — are made immediately free on journal websites. Upfront payments from libraries will fund the access.

Beat Procrastination and Get Motivated with The Procrastination Equation

Beat Procrastination and Get Motivated with The Procrastination Equation | cleav goes webwalking | Scoop.it

The next time you feel unmotivated, consult this handy flowchart for a cure. Based on the book The Procrastination Equation by Piers Steel, the chart guides you to do one of four things associated with motivation and defeating procrastination.

Researchers have previously identified the mathematical formula for procrastination. Motivation is the result of how much you value completing a task multiplied by your perceived odds of success. Then that's divided by how impulsive (distractible) you are and the length of time until you have to complete the task.

 

To help you stop dawdling, Alex Vermeer created this easy-to-follow flowchart. Increase the pleasantness and value of the task by following the squares on the left. Decrease impulsiveness by following the ones on the right. Increase expectancy of success with the squares at the bottom. Rinse and repeat until you finally get moving.

 

The poster is available for download in many sizes or you could order a high-res printed one.

Proof claimed for deep connection between primes

Proof claimed for deep connection between primes | cleav goes webwalking | Scoop.it
If it is true, a solution to the abc conjecture about whole numbers would be an ‘astounding’ achievement.

 

The usually quiet world of mathematics is abuzz with a claim that one of the most important problems in number theory has been solved.

 

Mathematician Shinichi Mochizuki of Kyoto University in Japan has released a 500-page proof of the abc conjecture, which proposes a relationship between whole numbers — a 'Diophantine' problem.

 

The abc conjecture, proposed independently by David Masser and Joseph Oesterle in 1985, might not be as familiar to the wider world as Fermat’s Last Theorem, but in some ways it is more significant. “The abc conjecture, if proved true, at one stroke solves many famous Diophantine problems, including Fermat's Last Theorem,” says Dorian Goldfeld, a mathematician at Columbia University in New York. “If Mochizuki’s proof is correct, it will be one of the most astounding achievements of mathematics of the twenty-first century.”

Your Goals Are Holding You Back - dan shipper

Setting goals and keeping track of your progress is putting the cart before the horse. It is certainly a part of getting better at what you do. BUT it’s not Step One in the process.

Oddly enough, in my experience, moving away from willpower-driven progress is more fun and helps you become more emotionally engaged in what you’re doing. Which produces better results, and allows you to maintain your rate of progress. So if setting goals is not Step One, then what is step one?

Step One is concentrating on habit creation.

In theory the idea is very simple: using tips and tricks, and keeping track of your progress, and improving every day are optimizations. They might make you 10% better, or 50% better, or even 1,000% better. But a 1,000% optimization on zero is still zero.

And so the biggest part of Step One is not to get better at doing, it’s to start doing.

Work Less to Get More Done

Work Less to Get More Done | cleav goes webwalking | Scoop.it

"For several years now I’ve used a productivity trick called weekly/daily goals. I’ve written about it many times before, but the gist is simple:
1. You keep two to-do lists, one for the day and one for the week.
2. As the week goes by, move items from your weekly to daily list.
3. When working, only focus on the daily list. When it’s done, you’re finished for the day.
The power of this method is that it forces you to not work on certain things. You avoid the infinite to-do list syndrome of constantly procrastinating because it feels too hard to get started."

Sherwood Anderson on Art and Life: A Letter of Advice to His Teenage Son, 1927

Sherwood Anderson on Art and Life: A Letter of Advice to His Teenage Son, 1927 | cleav goes webwalking | Scoop.it

“The object of art is not to make salable pictures. It is to save yourself.”

 

The quest to find one’s purpose and live the creative life boldly is neither simple nor easy, especially for a young person trying to make sense of the world and his place in it.

 

In the spring of 1926, Sherwood Anderson sent his seventeen-year-old son John a beautiful addition to history’s most moving and timeless letters of fatherly advice. Found in Posterity: Letters of Great Americans to Their Children(UK; public library), the missive offers insight on everything from knowing whose advice not to take to the false allure of money to the joy of making things with your hands

The Art of Chance-Opportunism in Creativity and Scientific Discovery: A 1957 Guide

The Art of Chance-Opportunism in Creativity and Scientific Discovery: A 1957 Guide | cleav goes webwalking | Scoop.it
One recurring emphasis by Beveridge is the eclecticism of influence necessary for true originality and the idea that creativity is combining and connecting things:

"Successful scientists have often been people with wide interests. Their originality may have derived from their diverse knowledge … Originality often consists in linking up ideas whose connection was not previously suspected.
[…]
"Therefore reading ought not to be confined to the problem under investigation nor even to one’s own field of science, nor, indeed, to science alone."

[...]

To those who deny the combinatorial nature of creativity, the poet Lord Byron quipped:

"To be perfectly original one should think much and read little, and this is impossible, for one must have read before one has learnt to think."

Using an algorithm adapted from web browser Google Chrome, engineering doctorate candidate Ed Manley and spatial analysis lecturer James Cheshire, both from University College London, were able to detect the language of tweets sent from the London area over the summer. Of 3.3 million tweets, 92.5 per cent are, not surprisingly, in English. The biggest tweeting tongues after that are Spanish (grey), French (red), Turkish (dark blue), Arabic (green), Portuguese (purple), German (orange), Italian (yellow), Malay (turquoise) and Russian (pink).

Short Sharp Science: Tron-like map of bike journeys reveals London's hubs

Short Sharp Science: Tron-like map of bike journeys reveals London's hubs | cleav goes webwalking | Scoop.it

It's a snapshot of 5 million bicycle journeys - and a handy map of London's commuter hotspots.

 

This image is a still from an animation created by visualisation specialist Jo Wood at City University in London. He based it on data from the first 5 million journeys pedalled in the Barclays Cycle Hire scheme since its launch in July 2010.

 

In the animation (see below) the least travelled routes begin to fade out after about 15 seconds - "like a graphic equaliser," says collaborator Andrew Huddart, also at City University. Around the 1-minute mark, structure emerges from the chaos and three major systems become clear: routes around, and through, the lozenge-shaped Hyde Park in the west, and commutes in and out of King's Cross St Pancras in the north and between Waterloo and the City in the east.

CultureLab: Making science fiction a reality

CultureLab: Making science fiction a reality | cleav goes webwalking | Scoop.it

NEAL STEPHENSON has a big idea. He imagines a 20-kilometre-high steel tower that reaches into the stratosphere. From that height, weather patterns would be distant swirls. Planes could save fuel by docking at the tower rather than landing, and space missions could do the same by launching from it.

A science-fiction novelist, Stephenson is not just using his idea as the basis for a story. The author of the critically acclaimed Snow Crash is taking the unusual step of teaming up with a structural engineer, Keith Hjelmstad at Arizona State University (ASU) in Phoenix, to work out how to actually build the tower.

The project is not a one-off. This month will see the launch of the Center for Science and the Imagination, an ASU project that will bring together scientists, engineers, artists and writers and encourage them to think big. The idea is to team artists and authors with ASU researchers to turn science fiction into reality.

What Does It Mean To Love What You Do? - dan shipper

"Do something you love."
I hear that all the time. I hear it from articles, from entrepreneurs, from books. But the problem with it is that for a long time I had no idea what it meant. Seriously? Do something I love?

First off what hell is love? Second how do I find what I love? Third how do I know if I love something? In short telling me to do "what I love" is basically telling me nothing. Thanks for nothing self help books.

So how do we start figuring out what we love? Let's start off small. Just kidding, let's attack one of the biggest questions of our lives: how do you define love?

Atoms interfere one at a time - physicsworld.com

Atoms interfere one at a time - physicsworld.com | cleav goes webwalking | Scoop.it

Physicists in the US say they are the first to directly observe single-atom interference over distances much greater than the atom's coherence length. The experiment involves using optical tweezers and a sequence of laser pulses to "bounce" the atom along two different paths that meet up after about 1 ms. The team says that if the precision of the experiment can be improved, it could provide new information about the possible existence of non-Newtonian gravity at micron distances. The researchers say the technique could also be used to study the tiny force that arises between an atom and a conducting surface, dubbed the "Casimir–Polder effect".
