1900–01 MIT Engineers men's ice hockey season. The 1900–01 MIT Engineers men's ice hockey season was the 3rd season of play for the program.

Season
MIT scheduled several games for the season, however, many were postponed or cancelled. Some of the university's records about this season are missing as the school yearbook skips from the 1900 season to the 1902 season. The record of only one game appears in the university newspaper and while it does mention a few others, there's no evidence that any more games were played.

The team did not have a head coach but Roger Burr served as team manager and president.

Note: Massachusetts Institute of Technology athletics were referred to as 'Engineers' or 'Techmen' during the first two decades of the 20th century. By 1920 all sports programs had adopted the Engineer moniker.

Ford Levacar Mach I. The Ford Mach I, also known as the Ford Levacar Mach I, is a concept car hovercraft developed by the Ford Motor Company in the 1950s. The Mach I was a single-seat automobile which rode on pressurized air, not wheels. Its name was inspired by the speed Mach 1, an aspiration speed not yet achieved by vehicles at the time. It used air pressure at a force of  to provide lift and propulsion. In experiments,  was used so that  was needed for levitation and  propelled it . An advertisement for the Mach I appeared in the magazine Boys' Life in 1960, in which it indicated the single-seater's dimensions:  long;  high;  wide.

The Levacar project was led by Andrew A. Kucher (a Ford Vice-President for Engineering and Research) and David J. Jay (a Senior Development Engineer). Kucher had initially conceived the concept around 1930. One of the lead designers was Gale Halderman, known for being the initial designer of the Ford Mustang. In addition to the Mach I automobile, the project also developed a similarly outfitted scooter, the Levascooter. In experiments on a circular track, vehicles would raise  off the ground and could jump  obstacles.

The Mach I was displayed for about two years in the late 1950s in Dearborn, Michigan.

Malkus waterwheel. The Malkus waterwheel, also referred to as the Lorenz waterwheel or chaotic waterwheel, is a mechanical model that exhibits chaotic dynamics. Its motion is governed by the Lorenz equations. While classical waterwheels rotate in one direction at a constant speed, the Malkus waterwheel exhibits chaotic motion where its rotation will speed up, slow down, stop, change directions, and oscillate back and forth between combinations of such behaviours in an unpredictable manner. 

This variant waterwheel was developed by Willem Malkus in the 1960s. As a pedagogic tool, the Malkus waterwheel became a paradigmatic realization of a chaotic system, and is widely used in the teaching of chaos theory.

In addition to its pedagogic use, the Malkus waterwheel has been actively studied by researchers in dynamical systems and chaos.

In the Malkus waterwheel, a constant flow of water pours in at the top bucket of a simple circular symmetrical waterwheel and the base of each bucket is perforated to allow the outflow of water. At low rates of inflow, the wheel rolls permanently in the same direction. At higher rates of inflow, the waterwheel enters a chaotic regime where it reverses its directionality, accelerates and decelerates in an apparently unpredictable way. A further increase in the incoming flow makes the waterwheel return to a periodic state, where it oscillates back and forth at fixed intervals. Since it was first proposed, many experimental and real-world applications have been related to the waterwheel dynamics. These include instances like the dynamics for electro-rotation, haline oceanic flow, and Rayleigh–Benard convection.

History 
Originating from an exhibition at Capitan Boiso Lanza Air Base, the museum was founded on 8 August 1954 by Colonel (Av.) Jaime Meregalli. The museum was moved a number of times in its early years, first to Air Base No. 1 in Carrasco and shortly thereafter to the Cilindro Municipal in downtown Montevideo. It became the Colonel Jaime Meregalli Aeronautical Museum on 17 March 1993. On 4 December 1997, the museum suffered a fire which damaged a number of aircraft in the collection. Eventually, in 2013, it was moved to Carrasco International Airport.

Lithium orthosilicate. Lithium orthosilicate is a compound with the chemical formula Li4SiO4. It is a white ceramic compound, which melts congruently at a temperature of .

Lithium orthosilicate is of primary interest towards carbon dioxide capture, as this compound reacts with CO2 at elevated temperatures to form lithium carbonate, and has been implemented in limited scale in such applications. 
Further applications of Li4SiO4 include solid electrolytes for lithium-ion batteries, specifically solid state batteries, and tritium breeding materials, as a component of the breeding blanket for planned fusion energy systems such as ITER.

Canasite. Canasite is a mineral whose name is derived from its chemical composition of calcium (Ca), sodium (Na), and silicon (Si). It was approved in 1959 by IMA.

Properties 
It is a relatively rare mineral. It occurs as aggregates in charoite, creating cabochons when contrasted against swirling purple charoite. It is extremely rare for canasite to be faceted. As crystals, it occurs in a size up to 10 cms, but in platy aggregates it can reach up to 20 cms in size. It is also granular. Twinning is usual, and can occur as polysynthetic, which is when multiple twins align in a parallel. It has a barely detectable 1.12% potassium radioactivity based on the GRapi unit (Gamma Ray American Petroleum Institute Units). It consists of mostly oxygen (41.98%), silicon (26.8%) and calcium (15.93%), but otherwise contains sodium (7.31%), potassium (6.22%), which gives its radioactive properties, fluorine (1.51%) and hydrogen (0.24%). There are two varieties of canasite: fluorcanasite and frankamenite. Purple canasite may be confused with stichtite, but recent research has found that the mineral advertized as canasite is a new specimen.

Occurrences and localities 
Canasite has been found in three localities, all in Russia. In Khibiny massif, it grows in a differentiated alkalic massif in pegmatites, and in the Murun massif, it grows in charoitic rocks. It also occurs in the Kola Peninsula. In Khibiny massif, it is associated with titanite, eudialyte, orthoclase, nepheline, pyroxene, lamprophyllite and fenaksite, while the specimens from Murun massif are usually associated with charoite, tinaksite and miserite.

Wiegand sensor. Wiegand sensors are magnetic sensors that do not need any external voltage or current, and make use of the Wiegand effect to generate a consistent pulse every time magnetic field polarity reverses. Wiegand sensors are made by wrapping a coil around a Vicalloy wire core, which, due to the hysteresis inherent in the Wiegand effect, induces a pulse in the coil each time the magnetic polarity of the Vicalloy wire core reverses. They can be used in a range of magnetic sensing applications and have the additional advantage that the energy of each pulse can be harvested.

Energy harvesting 
The consistency of the pulses produced by Wiegand sensors can also be used to provide energy for ultra-low power electronics to be operated using a single pulse. In addition, successive pulses can be stored to offset energy demand of low-power energy circuits. Alternatively, the pulses can be used to trigger, or ‘wake-up’, intermittently powered electronic circuits.

In certain applications, both functions of the pulses (magnetic sensing and energy harvesting) are exploited. The pulse energy is used to power ultra-low power circuitry or ICs which, in turn, use the timing of the pulses to perform calculation tasks (e.g. count event data).

Applications
Typical applications fall into three main categories; pulse generation applications, power transmission applications and combined sensing and energy harvesting applications.

Pulse generation
As a reliable source of consistently timed pulses, Wiegand sensors are used in industrial and commercial flow-metering applications (e.g. water and gas), and also to calculate rotation speed in tachometers (e.g. high-speed trains).

Power transmission
By placing the Wiegand sensor within an oscillating electro-magnetic fields (e.g. from a Helmholtz coil), Wiegand sensors can be used to provide energy for low power applications in environments where high frequency transmission is challenging (e.g. transcutaneous power for medical devices).

Sensing and energy harvesting
Wiegand sensors are commonly used in ‘Batteryless’ rotary encoder technology for self-powered revolution counting. Harnessing both the timing of the pulses and the pulse energy, such rotary encoders provide reliable multiturn counting even in the absence of external power or batteries.

Bertil Dillner. Bertil Dillner (12 May 1923 in Lit Jämtland, Sweden – 9 May 2015 in Linköping) was a Swedish aeronautical engineer and aerodynamic expert. He was significant in the development of delta wing aerodynamics and supersonic flight concepts. Dillner served for many years as manager of Boeing engineering design offices.

Biography

FFA 
After graduation 1949, as Master of Science Civil engineer in Aeronautics at KTH Royal Institute of Technology, Stockholm Sweden he worked at the FFA, the Swedish National Aeronautical Research Institute.

Saab 
From 1954 to 1967 at Saab AB, he participated in the aerodynamic core of the projects for Saab 35 Draken and Saab 37 Viggen, both cutting-edge technology during the Cold War and the Nuclear arms race. He worked under Erik Bratt and Tore Gullstrand, in the Saab design team with Hermann Behrbohm, Olof Ljungström and Einar Bergström.

In the shadow of the Cold War and the nuclear arms race the client, the Swedish Air Force's desire in the 1950s to the 1970s (the Defence Act of 1958) was to be able to swiftly attack strategic nuclear weapons-bombers such as Tupolev Tu-16 before they reached their targets. This with really fast supersonic-delta wing-fighter aircraft such as Saab 35 Draken, where speed and preparedness were the key factors. The Swedish Air Force's need were also landing operation-defenses over the surrounding seas with attack aircraft as well as ultra-fast reconnaissance aircraft planes such as the Saab 37 Viggen. Economy and materials engineering for friction heat of the atmosphere set the limit for speed. This generated large orders to build a very large air force and resources for development.

Dillner and Hermann Behrbohm made significant efforts in the design of Saab 37 Viggen, and in particular the design and tests of the canard-wing construction.

Boeing 
From 1967 to 1981, Dillner was employed by Boeing Commercial Airplanes in Seattle, US to work with the supersonic Boeing 2707 SST passenger jet 1967–1972.

At Boeing he also become involved with the aerodynamics of the extreme supersonic aviation at the re-entry of Space Shuttle 1971-1972 and Boeing Preliminary Design Group and ex QSRA transporter studies.

Dillner was aerodynamic chief engineer at Boeing Commercial Airplanes 1972–1981. He also became an American citizen while in Seattle.

From 1981 to 1988, Dillner was employed by Boeing Defense, Space & Security in Seattle as aerodynamic chief engineer 1981-1985 and chief engineer 1985-1988 until his retirement. After retirement, he made some consulting assignments were made for Aermacchi and Saab 2000.

Compound life
He was active in the American Institute of Aeronautics and Astronautics and co-founder of their Aerodynamic Committee.

Bertil Dillner chaired the Swedish Club North West between 1996 and 1997 and returned to Linköping and Sweden in 2005.
