Second Wind

runner's high

Second wind is a phenomenon in distance running, such as marathons or road running (as well as other sports), whereby an athlete who is out of breath and too tired to continue suddenly finds the strength to press on at top performance with less exertion.

The feeling may be similar to that of a ‘runner’s high.’ Some scientists believe the second wind to be a result of the body finding the proper balance of oxygen to counteract the buildup of lactic acid in the muscles. Others claim second winds are due to endorphin production. A second wind phenomenon is also seen in some medical conditions, such as glycogen storage disease type V.

Soundwalk

World Soundscape Project

soundwalk is a walk with a focus on listening to the environment. The term was first used by members of the World Soundscape Project under the leadership of composer R. Murray Schafer in Vancouver in the 1970s.

Hildegard Westerkamp, from the same group of artists, defines soundwalking as ‘… any excursion whose main purpose is listening to the environment. It is exposing our ears to every sound around us no matter where we are.’

Bromide

From Cliché to Archetype

Bromide [broh-mahyd] in literary usage means a phrase, cliché, or platitude that is trite or unoriginal. It can be intended to soothe or placate; it can suggest insincerity or a lack of originality in the speaker. It can also refer to a commonplace or tiresome person, a bore.

A now outdated usage of ‘bromide’ is a photographic print, stemming from the use of silver bromide in photographic films, emulsions and papers. Its original usage was as a chemical term, referring to bromine salts.

QAnon

Anonymous

QAnon is a far-right conspiracy theory detailing a supposed secret plot by an alleged ‘deep state’ against U.S. President Donald Trump and his supporters. The theory began with an October 2017 post on the anonymous imageboard 4chan by someone using the name Q, a presumably American individual that may have later grown to include multiple people, claiming to have access to classified information involving the Trump administration and its opponents in the United States.

Q has falsely accused numerous liberal Hollywood actors, Democratic politicians, and high-ranking officials of engaging in an international child sex trafficking ring, and has claimed that Donald Trump feigned collusion with Russians in order to enlist Robert Mueller to join him in exposing the ring and preventing a coup d’état by Barack Obama, Hillary Clinton, and George Soros.

Autorhythmicity

automaticity

Autorhythmicity [aw-toh-rith-miss-uh-tee], or automaticity, refers to the heart’s ability to spontaneously generate an electric charge without outside help. Cardiac electrical activity originates in the sinoatrial node (SAN) and is propagated via the ‘His-Purkinje’ network, the fastest conduction pathway within the heart. This pathway is known as the electrical conduction system of the heart.

The electrical signal travels from the SAN, which stimulates the atria to contract, to the atrioventricular node (AVN), which slows down conduction of the action potential from the atria to the ventricles. This delay allows the ventricles to fully fill with blood before contraction. The signal then passes down through a bundle of fibers called the ‘bundle of His,’ located between the ventricles, and then to the ‘purkinje’ fibers at the bottom (apex) of the heart, causing ventricular contraction.

Rapport

Rapport [ra-pawr] is a close and harmonious relationship in which the people or groups concerned are ‘in sync’ with each other, understand each other’s feelings or ideas, and communicate smoothly. Methods for increasing interpersonal rapport in domains like education, medicine, or sales include coordination (or ‘mirroring’), showing your attentiveness to the other, building commonality, and managing the other’s self-perception (also called ‘face’ management).

The word stems from the old French verb ‘rapporter’ which means literally to carry something back; and, in the sense of how people relate to each other means that what one person sends out the other sends back. For example, they may realize that they share similar values, beliefs, knowledge, or behaviors around politics, music or sports. This may also mean that the participants engage in reciprocal behaviors such as posture mirroring or in increased coordination in their verbal and nonverbal interactions.

Cognitive Bias

cognitive bias is when someone makes a bad choice that they think is a good choice. This bias is an important part of the study of cognitive psychology, which looks at basic actions of the mind, such as thought, feeling, problem solving, memory, and language.

Cognitive biases are often a side effect of evolutionary changes. Some behaviors that were beneficial for primitive humans and animals are unsuited to modernity. Others are adaptive and may lead to more effective actions in a given context.

Dooring

Dutch Reach

Dooring is a traffic collision in which a cyclist rides into a car door or is struck by a car door that was opened quickly without checking first for cyclists by using the side mirror and/or performing a proper shoulder check out and back.

The width of the door zone in which this can happen varies, depending upon the model of car one is passing. The zone can be almost zero for a vehicle with gull-wing doors or much larger for a truck. Dooring can happen when a driver has parked and is exiting their vehicle, or when passengers are exiting from cars, taxis and ride shares into the path of a cyclist approaching from the rear.

Cold Turkey

Delirium tremens

Cold turkey refers to the abrupt cessation of a substance dependence and the resulting unpleasant experience, as opposed to gradually easing the process through reduction over time or by using replacement medication. The term comes from the piloerection or ‘goose bumps’ that occurs with abrupt withdrawal from opioids, which resembles the skin of a plucked, refrigerated turkey.

Sudden withdrawal from drugs such as alcohol, benzodiazepines, and barbiturates can be extremely dangerous, leading to potentially fatal seizures. For long-term alcoholics, going cold turkey can cause life-threatening delirium tremens, rendering this an inappropriate method for breaking an alcohol addiction.

Enchroma

Color blindness

Enchroma lenses are glasses designed to improve and modify some aspects of color vision deficiency for color blind people. Glass scientist Dr. Donald McPherson invented Enchroma glasses by accident. He originally invented this type of lens to protect surgeons during laser operations. In 2002 at the Ultimate Frisbee tournament in Santa Cruz, California McPherson lent a pair to a friend who was color blind. His friend saw colors he had never seen before.

McPherson started studying color blindness, and with Andrew Schmeder founded the company EnChroma Inc. in 2010 to sell glasses that compensate for color vision deficiency. Enchroma glasses target people with difficulties in distinguishing reds and greens. The first pair of commercial glasses were released in 2012.
