Yesterday was the flight of the caterpillars. Or as the birds name it: buffet day. Platoons of caterpillars decided all at once to drop on silk cords from their oak tree canopy homes. These soldiers are sleepers, waiting to wreak their havoc later in the season.

Quantum Entanglement Drives the Arrow of Time, Scientists Say | Simons Foundation - https://www.simonsfoundation.org/quanta...
"Now, physicists are unmasking a more fundamental source for the arrow of time: Energy disperses and objects equilibrate, they say, because of the way elementary particles become intertwined when they interact — a strange effect called “quantum entanglement.” “Finally, we can understand why a cup of coffee equilibrates in a room,” said Tony Short, a quantum physicist at Bristol. “Entanglement builds up between the state of the coffee cup and the state of the room.”" - Todd Hoff from Bookmarklet
"When two particles interact, they can no longer even be described by their own, independently evolving probabilities, called “pure states.” Instead, they become entangled components of a more complicated probability distribution that describes both particles together. It might dictate, for example, that the particles spin in opposite directions. The system as a whole is in a pure... more... - Todd Hoff
"Using an obscure approach to quantum mechanics that treated units of information as its basic building blocks, Lloyd spent several years studying the evolution of particles in terms of shuffling 1s and 0s. He found that as the particles became increasingly entangled with one another, the information that originally described them (a “1” for clockwise spin and a “0” for... more... - Todd Hoff

"In the new story of the arrow of time, it is the loss of information through quantum entanglement, rather than a subjective lack of human knowledge, that drives a cup of coffee into equilibrium with the surrounding room. The room eventually equilibrates with the outside environment, and the environment drifts even more slowly toward equilibrium with the rest of the universe. The giants... more... - Todd Hoff
From what I understand from Shannon's formulation of information and entropy, though, maximal entropy *is* maximal information. At maximum entropy, you need to describe the state of every particle in order to describe the state of the system. At minimum entropy, you only need a few bits of information to describe the state of the entire system—if you know the state of a few particles,... more... - Victor Ganata

"As you can see, the cost of solar PV has come from – quite literally – off the charts less than a decade ago to a point where Bernstein says solar PV is now cheaper than oil and Asian LNG (liquefied natural gas). It does its calculations on an MMBTU basis. MMBTU is the standard unit of measure for liquid fuels, often referred to as one million British thermal units." - Todd Hoff from Bookmarklet

March Was 4th Warmest on Record Globally | Climate Central
"March 2014 was the fourth-warmest March on record globally, according to recently released NASA data, making it the 349th month — more than 29 years — in which global temperatures were above the historic average. The amounts that temperatures around the world differed from the historic average. Credit: NOAA The planet’s average March temperature was 57.9°F — 0.7°C (or 1.2°F) above the average temperature from 1951-1980 — behind only the March of 2002, 2010 and 1990, in that order. Data is still coming in that could change the temperature deviation from this March, but likely only a few hundredths of a degree in either direction, said climate scientist Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, which compiles the temperature data." - Todd Hoff from Bookmarklet

Farmer Robert Sampson ploughs fields in the way his family has since 1885 | Mail Online
"Eight mighty horses toil in a farmer's field in an image that evokes an idyllic rural Britain at risk of vanishing forever. Robert Sampson is shunning modern machinery and employing old-fashioned horse power on his land in Hampshire. Five generations of his family have used this method to plough the fields since 1885. And the 58-year-old is keen to keep the tradition alive. Every day, he takes his Percherons out to plough his 256 acre plot. The method may take a little longer than using machinery, but he saves on diesel and road tax as his horses are content to munch grass at the end of a day’s labour. He said: ‘I do it because I love it. People think I’m mad … and there are times when I think I am too!’" - Todd Hoff from Bookmarklet

The new pulse of digital music
"Besides creating their powerful music, the students have invented a series of interfaces and musical gadgets. The first is the app sensorUDP, which transforms musicians’ smartphones into motion sensors. Available in the Android app store and compatible with iPhones, it allows performers to layer up to eight programmable sounds and modify them by moving their phone. Music student Pieteke MacMahon modified the app to create an iPhone Piano, which she plays on her wrist, thanks to a mount created by engineering classmates. As she moves her hands up, the piano notes go up in pitch. When she drops her hands, the sound gets lower, and a delay effect increases if her palm faces up. “Audiences love how intuitive it is,” says the composition major. “It creates music in a way that really makes sense to people, and it looks pretty cool onstage.”" - Todd Hoff from Bookmarklet

How to Use Swales on Your Homestead - http://104homestead.com/swales-...
"Simply defined, a Swale is a Ditch dug on Contour that captures water so it can slowly soak into the land. We are all probably familiar with a ditch. Well then, what the heck does “on contour” mean?  The easiest way I have found to understand this concept is to think of a topographical map, which depicts changes in elevation." - Todd Hoff from Bookmarklet
Swales are important for controlling storm runoff. Ever moreso as more and more of our cities' surfaces become impermiable. We had one on the boundary between our sideyard and our neighbor's sideyard and it kept our basements from flooding many a time. In other words, swales are swell. #sorry #dontHitMe - Jkram|ɯɐɹʞſ

"In short, we’re giving huge sums to the financial industry while receiving little or nothing — maybe less than nothing — in return. Mr. Philippon puts the waste at 2 percent of G.D.P. Yet even that figure, I’d argue, understates the true cost of our bloated financial industry. For there is a clear correlation between the rise of modern finance and America’s return to Gilded Age levels of inequality." - Todd Hoff from Bookmarklet

Is global warming just a giant natural fluctuation? | Research and International Relations - McGill University
"An analysis of temperature data since 1500 all but rules out the possibility that global warming in the industrial era is just a natural fluctuation in the earth’s climate, according to a new study by McGill University physics professor Shaun Lovejoy. The study, published online April 6 in the journal Climate Dynamics, represents a new approach to the question of whether global warming in the industrial era has been caused largely by man-made emissions from the burning of fossil fuels. Rather than using complex computer models to estimate the effects of greenhouse-gas emissions, Lovejoy examines historical data to assess the competing hypothesis: that warming over the past century is due to natural long-term variations in temperature. “This study will be a blow to any remaining climate-change deniers,” Lovejoy says. “Their two most convincing arguments – that the warming is natural in origin, and that the computer models are wrong – are either directly contradicted by this analysis, or simply do not apply to it.”" - Todd Hoff from Bookmarklet

The Zero Marginal Cost Society: The Internet of Things, the Collaborative Commons, and the Eclipse of Capitalism
"In The Zero Marginal Cost Society, New York Times bestselling author Jeremy Rifkin describes how the emerging Internet of Things is speeding us to an era of nearly free goods and services, precipitating the meteoric rise of a global Collaborative Commons and the eclipse of capitalism. Rifkin uncovers a paradox at the heart of capitalism that has propelled it to greatness but is now taking it to its death—the inherent entrepreneurial dynamism of competitive markets that drives productivity up and marginal costs down, enabling businesses to reduce the price of their goods and services in order to win over consumers and market share. (Marginal cost is the cost of producing additional units of a good or service, if fixed costs are not counted.) While economists have always welcomed a reduction in marginal cost, they never anticipated the possibility of a technological revolution that might bring marginal costs to near zero, making goods and services priceless, nearly free, and abundant,... more... - Todd Hoff from Bookmarklet
Not sure if I'll buy this or not. Abundance seems a real possibility with nano manufacturing tech on the horizon, and as Marx noted our social structures mirror our economic structures, so this should be interesting in the large, I just don't see a connection with IoT. I reads too much like "and a miracle will occur." - Todd Hoff

Hive minds: Time to drop the fiction of individuality - opinion - 08 April 2014 - New Scientist
"To develop this new science, my students and I have been studying living laboratories. By distributing smartphones with special software to all the residents of several small communities, we could track their social interactions with their peers – both friends and acquaintances – and at the same time ask questions about their health, politics and spending behaviour. For instance, when we looked at weight gain, we found that people picked up new habits from exposure to the habits of peers, and not just through interactions with friends. This means that when everyone else in the office takes a doughnut, you probably will too. In fact, this type of exposure turned out to be more important than all the other factors combined, highlighting the overarching importance of automatic social learning in shaping our lives. We found that this same pattern held true for voting and consumer consumption. The largest single factor driving adoption of new behaviours was the behaviour of peers. Put... more... - Todd Hoff from Bookmarklet
"In light of this, perhaps we should ask how important individual choices are compared with shared habits. Here again the power of sharing ideas, as opposed to individual thinking, is clear. When we study decision-making in small groups, we find that the pattern of communication – who talked to whom and how much they talked – is far more important than the characteristics of the... more... - Todd Hoff
Hegel would love this - "Instead of individual rationality, our society appears to be governed by a collective intelligence that comes from the surrounding flow of ideas and examples; we learn from others in our environment, and they learn from us. A community with members who actively engage with each other creates a group with shared, integrated habits and beliefs. What social physics... more... - Todd Hoff
"Our culture and the habits of our society are social contracts, and both depend primarily upon social learning. As a result, most of our public beliefs and habits are learned by observing the attitudes, actions and outcomes of peers, rather than by logic or argument. Learning and reinforcing this social contract is what enables a group of people to coordinate their actions effectively." - Todd Hoff
"It is time that we dropped the fiction of individuals as the unit of rationality, and recognised that our rationality is largely determined by the surrounding social fabric. Instead of being actors in markets, we are collaborators in determining the public good. Indeed, our research has demonstrated that people are much more influenced by their social networks than by individual... more... - Todd Hoff
"This power of the social fabric on individual decision-making is, in fact, the real reason that privacy is so important. As Stanley Milgram's work on social conformity demonstrated many years ago, the power of social influence can lead people to both good and terrible behaviours, and can transform our behaviour to an extent that is scarcely believable. Without privacy, the power of... more... - Todd Hoff
Good book so far. There's a similarity between pruning trees to sculpt light to get the best fruit and shaping social networks to make the best decisions. It's disturbing though to think of what passes for decision making is just copying others. - Todd Hoff

Amoeba Eats Cells Alive | The Scientist Magazine®
"For decades, scientists assumed that the intestinal parasite Entamoeba histolytica killed human tissues with toxic molecules before ingesting them. They were wrong; it’s actually the other way around, according to a study published in Nature today (April 9). Katherine Ralston, a postdoctoral researcher at the University of Virginia, has shown that E. histolytica—a single-celled amoeba—tears chunks from host cells and eats them. These attacks eventually kill the cell, at which point the parasite moves on. E. histolytica is the only parasite known to attack tissues in this way—a process known as trogocytosis, after “trogo,” the Greek word for “nibble.”" - Todd Hoff from Bookmarklet
