π Ballistic Recovery Systems
Ballistic Recovery Systems, Inc. (commonly referred to as BRS Aerospace, or simply BRS) is a manufacturer of aircraft ballistic parachutes.
The company was formed in 1980 by Boris Popov of Saint Paul, Minnesota, after he survived a 400-foot (120Β m) fall in a partially collapsed hang glider in 1975. As a result, Popov invented a parachute system that could lower an entire light aircraft to the ground in the event of loss of control, failure of the aircraft structure, or other in-flight emergencies.
Popov was granted a U.S. patent on 26 August 1986 for the so-called Ballistic Recovery System (BRS) - patent US 4607814 A.
The company has two divisions: BRS Aviation and BRS Defense.

π Lucky iron fish
Lucky Iron Fish are fish-shaped cast iron ingots used to provide dietary supplementation of iron to individuals affected by iron-deficiency anaemia. The ingots are placed in a pot of boiling water to leach elemental iron into the water and food. They were developed in 2008 by Canadian health workers in Cambodia, and in 2012 a company, The Lucky Iron Fish Project, was formed to develop the iron fish on a larger scale, promote them among rural areas, and distribute them to non-governmental organization partners. Notably, recent research found that the iron ingot had no effect on anemia. It therefore recommended against its use in Cambodia and other countries with low levels of iron deficiency.

π Continuous Partial Attention
Linda Stone, a tech writer and consultant, coined the term continuous partial attention in 1998 to describe a modern adaptive behavior of continuously dividing one's attention. Stone has clarified that continuous partial attention is not the same as multi-tasking. Where multi-tasking is driven by a conscious desire to be productive and efficient, CPA is an automatic process motivated only by "a desire to be a live node on the network" or by the willingness to connect and stay connected, scanning and optimizing opportunities, activities and contacts in an effort to not miss anything that is going on.
Continuous partial attention is not necessarily a dysfunctional state. However, it may lead to increased stress and decreased ability to focus and concentrate on the present moment, prohibiting reflection, contemplation, and thoughtful decision making. The constant connectedness that is associated with continuous partial attention may also affect relationships, lower productivity levels, and lead to over-stimulation and a lack of fulfillment.
Linda Stone's research has focused on examples in the United States though she has posited that, "We may not all find ourselves in the same attention era at the same time. We are likely to find ourselves experiencing a flow: attraction to an ideal, taking the expression of the ideal to an extreme and experiencing unintended and less than pleasant consequences, giving birth to and launching a new ideal while integrating the best of what came before."

π Stellar Wind (code name)
"Stellar Wind" (or "Stellarwind") was the code name of a warrantless surveillance program begun under the George W. Bush administration's President's Surveillance Program (PSP). The National Security Agency (NSA) program was approved by President Bush shortly after the September 11, 2001 attacks and was revealed by Thomas Tamm to The New York Times in 2004. Stellar Wind was a prelude to new legal structures that allowed President Bush and President Barack Obama to reproduce each of those programs and expand their reach.

π Siddhartha
Siddhartha: An Indian novel (German: Siddhartha: Eine Indische Dichtung; German: [ziΛdaΚta] ) is a 1922 novel by Hermann Hesse that deals with the spiritual journey of self-discovery of a man named Siddhartha during the time of the Gautama Buddha. The book, Hesse's ninth novel, was written in German, in a simple, lyrical style. It was published in the United States in 1951 by New Directions Publishing and became influential during the 1960s. Hesse dedicated the first part of it to the French writer Romain Rolland and the second part to Wilhelm Gundert, his cousin.
The word Siddhartha is made up of two words in the Sanskrit language: siddha (achieved) + artha (what was searched for), which together means "he who has found meaning (of existence)" or "he who has attained his goals". In fact, the Buddha's own name, before his renunciation, was Siddhartha Gautama, prince of Kapilavastu. In this book, the Buddha is referred to as "Gotama".

Schonberg. Schwartz is credited with designing the language.
