Every Single Cognitive Bias in One Infographic. What goes into your morning cup of coffee, and what makes it possible?

Every Single Cognitive Bias in One Infographic

The obvious answer might be coffee beans, but when you start to account for additional costs, the scope of a massive $200+ billion coffee supply chain becomes clear. From the labor of growing, exporting, and roasting the coffee plants to the materials like packaging, cups, and even stir sticks, there are many underlying costs that factor into every cup of coffee consumed. The above graphic breaks down the costs incurred by retail coffee production for one pound of coffee, equivalent to about 15 cups of 16 ounce brewed coffee. Depression as a disease of modernity: explanations for increasing prevalence. The Inner Light Theory of Consciousness. Abstract The Inner Light Theory of Consciousness is based on an extraordinary assertion: human awareness exists within a manufactured reality, something that is distinct and separate from the external physical universe.

The Inner Light Theory of Consciousness

Our ability to dream shows that the brain contains the neural machinery to accomplish this feat. Further, the nature of human perception provides strong evidence that this reality creating machine is activated whenever we are conscious, and that we can be aware of nothing but this artificial reality. When we are awake, this inner reality is constructed to coarsely represent the physical environment around us.

When we dream, the reality creating machine is running amok, creating an inner reality that is chaotic and unrelated to the outside world. This mental architecture is consistent with evolutionary adaptation, the human perception of reality, and the nature of dreaming. I. II. III. IV. V. To Pay Attention, the Brain Uses Filters, Not a Spotlight. We can pick out a conversation in a loud room, amid the rise and fall of other voices or the hum of an air conditioner.

To Pay Attention, the Brain Uses Filters, Not a Spotlight

We can spot a set of keys in a sea of clutter, or register a raccoon darting into the path of our onrushing car. What Gut Bacteria Do to the Human Brain. Other research has examined entire humans, not just their bugs.

What Gut Bacteria Do to the Human Brain

A paper published in the May 2015 issue of Psychopharmacology by the Oxford University neurobiologist Phil Burnet looked at whether a prebiotic—a group of carbohydrates that provide sustenance for gut bacteria—affected stress levels among a group of 45 healthy volunteers. Some subjects were fed 5.5 grams of a powdered carbohydrate known as galactooligosaccharide, or GOS, while others were given a placebo. Previous studies in mice by the same scientists had shown that this carb fostered growth of Lactobacillus and Bifidobacteria; the mice with more of these microbes also had increased levels of several neurotransmitters that affect anxiety, including one called brain-derived neurotrophic factor.

Perhaps the most well-known human study was done by Mayer, the UCLA researcher. The Neuroscience of Consciousness. 1.

Meditation and Psychedelics

The increased focus on meditation in cognitive neuroscience has led to a cross-cultural classification of standard meditation styles validated by functional and structural neuroanatomical data (Lutz et al., 2008; Dahl et al., 2015; Fox et al., 2016). How a Kalman filter works, in pictures. I have to tell you about the Kalman filter, because what it does is pretty damn amazing.

How a Kalman filter works, in pictures

Surprisingly few software engineers and scientists seem to know about it, and that makes me sad because it is such a general and powerful tool for combining information in the presence of uncertainty. At times its ability to extract accurate information seems almost magical— and if it sounds like I’m talking this up too much, then take a look at this previously posted video where I demonstrate a Kalman filter figuring out the orientation of a free-floating body by looking at its velocity. 668111650 MIT.

A Change of Pace: The Fitness Benefits of Varying Your Running speed – Recoup Fitness. Many people take up running and chose a single distance and run it hard every time they train, trying to set a new personal best each time.

A Change of Pace: The Fitness Benefits of Varying Your Running speed – Recoup Fitness

Other people try to increase their distance but never change their pace, "one-pace-wonders" so to speak. Training in this way will result in temporary improvements to fitness, some instant gratification, and comfort, but will eventually lead to fitness plateaus and stale, boring workouts. Over the years the fitness community has developed a much better and effective way of training, one which targets different body systems by running different paces.

Henry Gustav Molaison (February 26, 1926 – December 2, 2008), known widely as H.M., was an American memory disorder patient who had a bilateral medial temporal lobectomy to surgically resect the anterior two thirds of his hippocampi, parahippocampal cortices, entorhinal cortices, piriform cortices, and amygdalae in an attempt to cure his epilepsy.[1] He was widely studied from late 1957 until his death in 2008.[2][3] His case played an important role in the development of theories that explain the link between brain function and memory, and in the development of cognitive neuropsychology, a branch of psychology that aims to understand how the structure and function of the brain relates to specific psychological processes.

Henry Molaison - Wikipedia

He resided in a care institute in Windsor Locks, Connecticut, where he was the subject of ongoing investigation.[4] Biography[edit] Most of Molaison's two hippocampi were removed bilaterally. He died on December 2, 2008.[3] Insights into memory formation[edit] What is minimum principal stress? Is it related to compressive stress? How does it differ from maximum principal stress? For alternating stress calculation, should we consider both maximum principal stress and minimum principal stress at a point? - Quora. 3.3 Demand, Supply, and Equilibrium. In this section we combine the demand and supply curves we have just studied into a new model.

The model of demand and supply uses demand and supply curves to explain the determination of price and quantity in a market. Does anybody actually understand Euler's formula intuitively? : math. Demystifying the Natural Logarithm (ln) – BetterExplained. After understanding the exponential function, our next target is the natural logarithm. Given how the natural log is described in math books, there’s little “natural” about it: it’s defined as the inverse of e^x, a strange enough exponent already. Behavioral Economics.
