    "With each interaction, Alexa is training to hear better, to interpret more precisely, to trigger actions that map to the user's commands more accurately, and to build a more complete model of their preferences, habits and desires. What is required to make this possible? Put simply: each small moment of convenience - be it answering a question, turning on a light, or playing a song - requires a vast planetary network, fueled by the extraction of non-renewable materials, labor, and data. The scale of resources required is many magnitudes greater than the energy and labor it would take a human to operate a household appliance or flick a switch. A full accounting for these costs is almost impossible, but it is increasingly important that we grasp the scale and scope if we are to understand and govern the technical infrastructures that thread through our lives. III The Salar, the world's largest flat surface, is located in southwest Bolivia at an altitude of 3,656 meters above sea level. It is a high plateau, covered by a few meters of salt crust which are exceptionally rich in lithium, containing 50% to 70% of the world's lithium reserves. 4 The Salar, alongside the neighboring Atacama regions in Chile and Argentina, are major sites for lithium extraction. This soft, silvery metal is currently used to power mobile connected devices, as a crucial material used for the production of lithium-Ion batteries. It is known as 'grey gold.' Smartphone batteries, for example, usually have less than eight grams of this material. 5 Each Tesla car needs approximately seven kilograms of lithium for its battery pack. 6 All these batteries have a limited lifespan, and once consumed they are thrown away as waste. Amazon reminds users that they cannot open up and repair their Echo, because this will void the warranty. The Amazon Echo is wall-powered, and also has a mobile battery base. This also has a limited lifespan and then must be thrown away as waste. According to the Ay

Originally published at the Institute for New Economic Thinking website Across the globe, a collective freak-out spanning the whole political system is picking up steam with every new "surprise" election, rush of tormented souls across borders, and tweet from the star of America's great unreality show, Donald Trump. But what exactly is the force that seems to be pushing us towards Armageddon? Is it capitalism gone wild? Globalization? Political corruption? Techno-nightmares? Rajani Kanth, a political economist, social thinker, and poet, goes beyond any of these explanations for the answer. In his view, what's throwing most of us off kilter - whether we think of ourselves as on the left or right, capitalist or socialist -was birthed 400 years ago during the period of the Enlightenment. It's a set of assumptions, a particular way of looking at the world that pushed out previous modes o

    "Risk of eternal lockdown. Hard questions need to be asked.. It's essential that we don't enter a semi-permanent state of emergency laws & basic rights switched on/off by the govt at will and without democratic scrutiny.. We cannot be locked down forever."

Physicists offer a new 'spin' on memory - 0 views

  •  
    Unlike conventional micro-transistors, magnetic tunnel junctions don't use the electrical charge of electrons to store information, but take advantage of a quantum-mechanical property that electrons have, which is referred to as "spin." Known as spintronics, computing technology based on magnetic tunnel junctions is still very much in the experimental phase, and applications are extremely limited. For example, the technology is used in aircraft and slot machines to protect stored data from sudden power outages. This is possible because magnetic tunnel junctions process and store information by switching the orientation of nano-scale magnets instead of moving electrons around as regular transistors do.

Asymmetric Information and the Pecking (Dis)Order* | Review of Finance | Oxford Academic - 0 views

  •  
    We study the classical problem of raising capital under asymmetric information. Following Myers and Majluf, we consider firms endowed with assets in place and riskier growth opportunities. When asymmetric information is concentrated on assets in place (rather than growth opportunities), equity-like securities are more likely to be optimal. In contrast, when asymmetric information falls on growth options, debt is optimal. Intuitively, this happens because when the asset with greater volatility is less affected by asymmetric information, issuing a security with greater exposure to upside potential (such as equity) can be less dilutive than issuing a security lacking such exposure (such as debt). Our results suggest that equity is more likely to dominate debt for younger firms with larger investment needs, endowed with riskier, more valuable growth opportunities. Thus, our model can explain why high-growth firms may prefer equity over debt, and then switch to debt financing as they mature.

Rediscovering Our Nature Instinct - 0 views

  • humans have a special capacity for perceiving and even anticipating natural phenomena and its patterns.
  • This innate sense has been largely forgotten, according to Gooley, because modern lifestyles demand we engage in mostly logical, deductive thinking, rather than using our intuition. Our ability to extract meaning from interrelated phenomena such as bird behavior, wind direction, plant growth, and sunlight has atrophied. By searching out these relationships and patterns in nature, Gooley writes, he has rediscovered a manner of experiencing the outdoors through intuition. With some practice, he assures us that we can, too.
  • Gooley describes the nature instinct as an awareness of the outdoors that allows him to observe and understand before conscious thought. He can sense direction from a tree or predict the behavior of animals, and only afterwards analyzes how he knew these things to be true. While he uses gut feeling or the sixth sense (a common but debunked theory of navigational aptitude in the 19th century and early 20th century), he settles instead on the term “fast thinking.”

  • What makes us unique as a species — in ancient and modern form — seems to be the complexity of thought and diversity of cultural practices we use to accomplish highly-skilled tasks such as navigation or problem solving. Whether we grow up tracking animals in the Kalahari or riding subways to school, humans seem able to switch quickly between intuitive and analytical modes, to both directly experience and step out of that experience and employ logic.
  • Through deciphering nature, he ventures that we can develop a more metaphysical understanding of the world: the ability to discern the big picture from many parts. “God,” he writes, “is only shorthand for the belief that there is some deeper meaning behind the things we sense and beneath the universe as a whole.”
