Falconar Avia. Falconar Avia was a Canadian aircraft manufacturer based in Edmonton, Alberta. The company specialized in the design and manufacture of kits and plans for amateur construction.

Founded in the 1960s by aeronautical engineer Chris Falconar, the company created a new aircraft fabric covering process called Hipec. The company also acquired a large list of aircraft designs that were either orphaned, like the Fauvel AV.36 glider, or long out of production and added their own designs to the line. The company provided plans and kits for all their designs, as well as parts and modification kits for other aircraft, including the Ercoupe.

In 1963 Falconar partnered with designer Marcel Jurca to produce the Jurca Gnatsum. By 1967, Falconar recommended a large number of changes to the design, which resulted in Jurca leaving the project. The modified aircraft was developed as the Falconar SAL Mustang, first flown in 1971 after significant cost overruns. Falconar Aircraft Ltd was sold to George F. Chivers and other investors and operated as Sturgeon Air Ltd with Falconar as an employee until 1973.

In 1985 Falconar established a new Falconar Aviation Ltd. with the assets of A & B Sales and the rights to many Jurca plans. Falconar also carried on operations as president of Hirth engines during this time. In 1994 the company was dissolved following legal disputes and was reestablished in its current form as Falconar Avia Inc. in 1995.

Falconar died on 9 September 2018. The company operations were wound up on 30 June 2019 and the design rights sold. Phil Hale of Manna Aviation bought the rights to the F-series aircraft, plus the Minihawk, 2/3 Mustang and the S14 Miranda. Leon McAtee of Excogitare LLC bought the rights to the Fauvel plans, while Todd Kammerdiener bought the rights to the Cubmajor and Cub Majorette.

John Burgeson. John W. Burgeson (19 August 1931 – 12 September 2016) was an IBM engineer who created the first computer baseball simulation game in 1961 on an IBM 1620 Computer in Akron, Ohio. Burgeson's invention was accepted and officially recognized by the National Baseball Hall of Fame in contribution.

A baseball fan and long-time member of SABR, Burgeson initially wrote the program on his own time for enjoyment. He shared the program with the company, and they included it as part of the IBM 1620 program library, for which it was the only game. The game was run by placing a deck of punch cards into a card reader, which in turn read them into the computer's memory. Users would pick a lineup from a roster of 50 players, the computer would pick its lineup from the remaining list and the simulation game was then played to completion based on the statistical probabilities for each batter and pitcher.

In 1961, a radio DJ at KDKA in Pittsburgh, Rege Cordic, read three of Burgeson's printed play-by-play game results on the air in a re-creation of the fictional games.

On September 12, 2016, at the age of 85, John W. Burgeson died. He is survived by his wife, eight children, twelve grandchildren, and five great grandchildren.

Mechanochromic luminescence. Mechanochromic luminescence (ML) references to intensity and/or color changes of (solid-state) luminescent materials induced by mechanical forces, such as rubbing, crushing, pressing, shearing, or smearing. Unlike "triboluminescence" which does not require additional excitation source other than force itself, ML is often manifested by external photoexcitation such as a UV lamp.Mechanochromic Fluorescent Materials, Editors: Jiarui Xu, Zhenguo Chi, Royal Society of Chemistry, Cambridge 2014, https://pubs.rsc.org/en/content/ebook/978-1-78262-322-9 The most common cause of ML is related to changes of intermolecular interactions of dyes and pigments, which gives rise to various strong (exciton splitting) and/or weak (Forster) excited state interactions. For example, a certain boron complex of sunscreen compound avobenzone exhibits reversible ML. A recent detailed study suggests that ML from the boron complex consists of two critical coupled steps: 1) generation of low energy exciton trap via mechanical perturbation; and 2) exciton migration from regions where photoexcitation results in a higher excited state. Since solid-state energy transfer can be very efficient, only a small fraction of the low-energy exciton traps is required when mechanical force is applied. As a result, for crystalline ML materials, XRD measurement may not able to detect changes before and after mechanical stimuli while its photoluminescence can be quite different.

Ernest Edwin Sechler. Ernest Edwin Sechler (1905-1979) was an aerospace engineer and scientist who specialized in thin-shell structures. He earned his doctorate in 1934 at Caltech as one of the early students of Theodore von Kármán with a dissertation on the mechanics of thin-plate compression.

Sechler contributed to the transition from wood to metal for construction of airframes.
A graduate student named Ernest E. Sechler (now a professor of aeronautics at Caltech) was reviewing research in the strength of thin metal plates which had been carried out by the National Bureau of Standards. Sechler reported that the engineers didn’t think that sheet metal could be used to make structural elements in an airplane because the metal would give way...Sechler’s report intrigued me.
Von Kármán showed that by stiffening with re-enforcing strips the "effective width" of metal sheets could be increased to withstand the load aloft. In 1934 Sechler wrote his thesis, The ultimate compressive strength of thin sheet metal panels, under von Karman's supervision.

"Development of light, fail-safe structure became the main theme of his  professional life." His thin-wall structures included missiles, booster rockets, and a movable dome for Palomar Observatory. This work was performed as consultant to NASA and industry.

Sechler wrote two of the standard references on shell structures: In 1942 he and Louis Dunn wrote Airplane Structural Analysis and Design. A decade later he contributed Elasticity in Engineering. In review, William Fuller Brown Jr. said that "Some of the basic topics are discussed least clearly."
Another reviewer noted that "many practical examples have been included to illustrate the various methods of structural analysis."

Sechler was responsible for the aeronautics graduate education at the Guggenheim Aeronautical Laboratory. He had "an unbelievable intuitive understanding of the potential of an incoming student."

Sechler was a Fellow of the American Institute of Aeronautics and Astronautics, a member of the American Association for the Advancement of Science, and of the California Academy of Science. He was elected to the National Academy of Engineering in 1979, the year of his death.

Thorn EMI Liberator. The Thorn EMI Liberator was a laptop word processor, produced in the United Kingdom by Thorn EMI Datatech, then in Feltham Middlesex, primarily intended for use by UK Government civil servants. Released in 1985, it is considered to be the first mass-produced British laptop. Thorn EMI Datatech simultaneously held the contracts for the repair of the Sinclair ZX80 and ZX81.

History
The design of the Liberator was instigated in 1983 by the UK Government's Central Computer and Telecommunications Agency (CCTA). It was envisaged as a portable device to allow civil servants to write and print their own reports, rather than using the services of typists. The CCTA initially contacted Dragon Data to develop the product, but the company went into administration shortly afterwards, and the engineering team were taken on by Thorn EMI to continue the project in 1984. 

The team consisted of five former Dragon Data employees.
Derek Williams headed up the business side of the endeavour, working closely with the CCTA and Thorn EMI senior management.
John Peacock managed the finances, vendors, and component suppliers.
Jan Wojna designed the hardware and packaging of the electronics into the custom designed case.
Duncan Smeed wrote the low level system software and worked closely with Digital Research on the operating system implementation.
John Linney created the embedded word processor and terminal emulation applications.

The Liberator entered limited production in early 1985 and was officially launched in September of that year, with PR from Aspect Public Relations. The journalist launch was the first promotional event held in the Cabinet War Rooms.

Despite plans for improved Liberator Mk1A and Mk2 variants, production of the Liberator ended in September 1986.

Description
The Liberator was based on a Zilog Z80A microprocessor and a Gate array implementing the screen controller, keyboard interface and other I/O logic. The LCD display had a resolution of 480 x 128 pixels, or 80 columns by 16 lines of text. Interfaces comprised two S5/8 serial ports and two expansion buses, one specifically for extra RAM. Two battery packs were available, a NiCad rechargeable pack giving 12 hours operation, or one holding four AA cells giving 16 hours. The Liberator had 40 kB of internal RAM as standard, plus an optional 24 kB which could be write-protected by means of an external switch and had its own button cell battery to provide non-volatile storage. Another 24 kB of non-volatile RAM could be plugged into the external RAM expansion bus.

The Liberator's custom wordprocessing software ran under the CP/M operating system.

The  external dimensions of the Liberator were 295 x 252 x 35mm.

Alwyn Crow. Sir Alwyn Douglas Crow   (10 May 1894 – 5 February 1965) was a British scientist involved in research into ballistics, projectiles and missiles from 1916 to 1953. At Fort Halstead he developed the Unrotated Projectile an antiaircraft weapon for the Royal Navy, used in the early period of World War II when the supply of anti-aircraft guns was limited. His obituary in The Times called him a Rocket Projectile Pioneer.

He was born in London, and educated at Queens' College, Cambridge. In World War I he was commissioned in the East Surrey Regiment, was injured in 1916, and Mentioned in Despatches.

In 1917, he was appointed to the staff of the Royal Arsenal, Woolwich. He served as Director of Ballistics Research at Woolwich 1919–1939. In 1934 British received intelligence reports about German developments in rocket weapons, and two years later Crow lead a new research team specializing in the topic. He later was Chief Superintendent of Projectile Development 1939-40, then Director and Controller of Projectile Development 1940-45, then Director of Guided Projectiles at the Ministry of Supply 1945–1946. He was in Washington, D.C. as Head of Technical Services to the British Joint Services Mission to Washington from 1946 to 1953. He retired in 1953, became a consultant and in 1960 settled in the United States with his second wife.

Honours
He was appointed an Officer of the Order of the British Empire in the 1918 Birthday Honours and made a Commander of the Order in the 1937 Coronation Honours. He was knighted in 1944.

Dornier DO-960. The Dornier DO-960 was a hybrid computer designed for the Dornier Do 31 experimental VTOL aircraft.

The hybrid approach was necessary because the computations for controlling VTOL were not feasible with digital computers available at that time. Vertical take-off requires solving complex differential equations in real-time. The DO-960 incorporates both digital computer and analog computer elements. The analog units are fit for solving computationally challenging differential equations, while the digital units are responsible for controlling the overall program flow. 

Although known primarily for aircraft, Dornier had been building analog and hybrid computers as soon as it started engineering vertical takeoff aircraft. The Dornier DO-960 was the last known hybrid computer of this series.

Cadabra (computer program). Cadabra is a computer algebra system designed specifically for the solution of problems encountered in classical field theory, quantum field theory and string theory.

The first version of Cadabra was developed around 2001 for computing higher-derivative string theory correction to supergravity.

Released under the GNU General Public License, Cadabra is free software.

Cadabra has extensive functionality for tensor polynomial simplification including multi-term symmetries, fermions and anti-commuting variables, Clifford algebras and Fierz transformations, implicit coordinate dependence, multiple index types and many more. The input format is a subset of TeX. Both a command-line and a graphical interface are available.

A Java program inspired by Cadabra called Redberry was developed between 2013 and 2016. It achieved faster speeds for most index contractions with an approach based on the graph isomorphism problem rather than canonicalisation.
