The use of “maths” instead of “math” is a difference in British English compared to American English. In British English, the word “mathematics” is often referred to as “maths,” with the added “s” signifying the plural form. This is consistent with how British English commonly shortens many words by adding an “s” to the end. For example, “physics” becomes “phys, “economics” becomes “econs,” and so on.

In contrast, American English typically shortens “mathematics” to “math” without the additional “s,” following a different pattern of abbreviation.

The reason for these linguistic differences is rooted in the historical development of the English language and regional linguistic variations that have evolved over time. British English and American English have diverged in certain aspects of vocabulary, pronunciation, and grammar, resulting in variations like “maths” and “math.” It’s important to note that neither is inherently correct or incorrect; they are just regional preferences.

 

 

 

 

 

 

 

 

 

 

 

 

 

Gresham College is a higher education institution located in London, UK. It was founded in 1597 under the will of Sir Thomas Gresham, a financier and merchant who left funds for the establishment of a college in the heart of the city.

The college’s original aim was to provide free public lectures in a range of subjects, including law, astronomy, geometry, and music. The lectures were intended to be accessible to anyone who was interested in learning, regardless of their background or social status.

Over the centuries, Gresham College has remained true to this mission, and today it continues to offer a range of free public lectures and events that are open to all.

Winslow Homer, “The Army of the Potomac–A Sharp-Shooter on Picket Duty” 1862

NCAA Rifle Competition began in 1980 and features both men’s and women’s teams competing together. The competition includes smallbore and air rifle events, with each athlete shooting in both disciplines.

The two primary events are smallbore rifle (also known as .22 caliber) and air rifle (using a .177 caliber air gun). Competitions typically involve both individual and team scoring, with athletes shooting a series of targets from different distances and positions.

Several U.S. colleges and universities have competitive rifle teams that participate in NCAA rifle competitions. Some of the notable institutions include:

  1. University of Alaska Fairbanks
  2. West Virginia University
  3. University of Kentucky
  4. Texas Christian University (TCU)
  5. University of Nebraska-Lincoln
  6. Murray State University
  7. Ohio State University
  8. University of Akron
  9. United States Military Academy (Army)
  10. University of Memphis
  11. North Carolina State University
  12. Jacksonville State University
  13. Morehead State University
  14. University of Mississippi (Ole Miss)
  15. U.S. Naval Academy (Navy)

The NCAA rifle competition serves as a pipeline for athletes aiming to compete in international events, including the Olympics where it was part of the inaugural modern Olympics in 1896.  Rifle events scheduled for the 2024 Olympics include:

  • 10m Air Rifle (Men and Women): Athletes will shoot from a standing position using a .177 caliber air rifle at a distance of 10 meters.
  • 50m Rifle Three Positions (Men and Women): Competitors will shoot from kneeling, prone, and standing positions using a .22 caliber smallbore rifle at a distance of 50 meters.
  • Mixed Team 10m Air Rifle: Teams composed of one male and one female shooter will compete together in the 10m air rifle event.

After athletic arena life safety obligations are met (governed legally by NFPA 70, NFPA 101, NFPA 110,  the International Building Code and possibly other state adaptations of those consensus documents incorporated by reference into public safety law) business objective standards come into play.   The illumination of the competitive venue itself figures heavily into the quality of digital media visual experience and value.

For almost all athletic facilities,  the consensus documents of the Illumination Engineering Society[1], the Institute of Electrical and Electronic Engineers[2][3] provide the first principles for life safety.  For business purposes, the documents distributed by the National Collegiate Athletic Association inform the standard of care for individual athletic arenas so that swiftly moving media production companies have some consistency in power sources and illumination as they move from site to site.  Sometimes concepts to meet both life safety and business objectives merge.

The NCAA is not a consensus standard developer but it does have a suite of recommended practice documents for lighting the venues for typical competition and competition that is televised.

“The National Game” | Arthur Streeton (1889)

Recreational sports, athletic competition, and the facilities that support it, are one of the most visible activities in any school, college or university.   They have requirements for safety and sustainability at the same scale as the academic and healthcare enterprises.   According to IBISWorld Market Research, Sports Stadium Construction was a $6.1 billion market in 2014, Athletic & Sporting Goods Manufacturing was a $9.2 billion market in 2015, with participation in sports increasing 19.3 percent by 2019 — much of that originating in school, college and university sports and recreation programs.

Accordingly, we have been following movement in the standards suites developed by the National Collegiate Athletic Association, the American Society of Testing Materials, and the National Operating Committee on Standards for Athletic Equipment (NOCSAE)   We also follow developments in the International Standards Organization’s  ISO/TC 83: Sports and other recreational facilities and equipment; a standard suite with the German Deutsches Institut für Normung (DIN) as the global Secretariat and the American National Standards Institute as the US Technical Advisory Group.

NOCSAE, the National Operating Committee on Standards for Athletic Equipment, is an independent and nonprofit standards development body with the mission to enhance athletic safety through scientific research and the creation of performance standards for athletic equipment.  From its mission statement:

NOCSAE is comprised of a board of directors representing stakeholders from a number of groups – including consumer and end users, equipment manufacturers and reconditioners, athletic trainers, coaches, equipment managers, and academic and sports medicine associations. These diverse interests have joined forces in an attempt to arrive at a common goal of reducing sports-related injuries.

The NOCSAE suite of standards follows American due process requirements set by ANSI.  Its standards development landing page is linked below where you will find instructions about how to comment on all NOCSAE titles at any time:

Wagner College v. Sacred Heart

At the moment, our advocacy resources give priority to athletic facilities (and their integration into #SmartCampus safety and sustainability systems) over athletic products There is sometimes interaction between the two — artificial turf and protective equipment standards need to support one another; for example.  However, our priority lies in persuading the leadership of the education industry get the user-interest (i.e. athletic facility managers) to participate in ANSI standards development processes.

The NOCSAE suite, and all other athletic and recreational product, facility and management standards is on the standing agenda of our periodic Sport colloquia.   See our CALENDAR for the next teleconference; open to everyone.

University of Michigan | Washtenaw County

About Last Night: #Paris2024

A standard Olympic-sized swimming pool is defined by the following dimensions:

  • Length: 50 meters
  • Width: 25 meters
  • Depth: A minimum of 2 meters
  • Lanes: 10 lanes, each 2.5 meters wide

The total area of the pool is therefore 1,250 square meters, and it holds approximately 2,500 cubic meters (or 2.5 million liters) of water.

https://standardsmichigan.com/australia/

The organization that sets the standards for Olympic-sized pools is the Fédération Internationale de Natation (FINA) — now World Aquatics — the governing body for swimming, diving, water polo, synchronized swimming, and open water swimming. FINA establishes the regulations for the dimensions and equipment of competition pools used in international events, including the Olympic Games.

The top ten universities that have produced Olympic champion:

  1. University of Southern California (USC)
  2. Stanford University
  3. University of California, Berkeley (UC Berkeley)
  4. University of Florida
  5. University of Texas at Austin
  6. University of Michigan – Michael Phelps, the most decorated Olympian of all time.
  7. Indiana University
  8. Auburn University
  9. University of Georgia
  10. University of Arizona

International Building Code Chapter 23: Wood

American Wood Council

“Arbor Day” 1932 | Grant Wood

Building schoolhouses with wood in the United States had significant practical and cultural implications, particularly during the 18th and 19th centuries. Wood was the most readily available and cost-effective material in many parts of the country. Abundant forests provided a plentiful supply, making it the logical choice for construction. The use of wood allowed communities to quickly and efficiently build schoolhouses, which were often the first public buildings erected in a new settlement.

Wooden schoolhouses were emblematic of the pioneering spirit and the value placed on education in early American society. These structures were often simple, reflecting the modest means of rural communities, but they were also durable and could be expanded or repaired as needed. The ease of construction meant that even remote and sparsely populated areas could establish schools, thereby fostering literacy and learning across the nation.

Moreover, wooden schoolhouses became cultural icons, representing the humble beginnings of the American educational system. They were often the center of community life, hosting social and civic events in addition to serving educational purposes. Today, preserved wooden schoolhouses stand as historical landmarks, offering a glimpse into the educational practices and community life of early America. Their construction reflects the resourcefulness and priorities of the early settlers who valued education as a cornerstone of their communities.

Building schoolhouses with wood presents several technical challenges, including durability, fire risk, maintenance, and structural limitations. Here are the key challenges in detail:

  1. Durability and Weather Resistance:
    • Rot and Decay: Wood is susceptible to rot and decay, especially in humid or wet climates. Without proper treatment and maintenance, wooden structures can deteriorate rapidly.
    • Pests: Termites and other wood-boring insects can cause significant damage, compromising the integrity of the building.
  2. Fire Risk:
    • Combustibility: Wood is highly flammable, increasing the risk of fire. This was a significant concern in historical and rural settings where firefighting resources were limited.
    • Safety Standards: Ensuring that wooden schoolhouses meet modern fire safety standards requires additional measures, such as fire-retardant treatments and the installation of fire suppression systems.
  3. Maintenance:
    • Regular Upkeep: Wooden buildings require frequent maintenance, including painting, sealing, and repairing any damage caused by weather or pests.
    • Cost: Ongoing maintenance can be costly and labor-intensive, posing a challenge for communities with limited resources.
  4. Structural Limitations:
    • Load-Bearing Capacity: Wood has limitations in terms of load-bearing capacity compared to materials like steel or concrete. This can restrict the size and design of the schoolhouse.
    • Foundation Issues: Wooden structures can experience foundation issues if not properly designed and constructed, leading to uneven settling and potential structural damage.
  5. Environmental Impact:
    • Deforestation: The widespread use of wood for construction can contribute to deforestation, which has environmental consequences. Sustainable sourcing practices are essential to mitigate this impact.
  6. Insulation and Energy Efficiency:
    • Thermal Insulation: Wood provides moderate thermal insulation, but additional materials and techniques are often required to ensure energy efficiency and comfort for students and staff.

Despite these challenges, wooden schoolhouses were popular in the past due to the availability of materials and ease of construction. Addressing these technical challenges requires careful planning, use of modern materials and techniques, and regular maintenance to ensure the longevity and safety of wooden schoolhouses.

Municipalities usually have specific land use or zoning considerations to accommodate the unique needs and characteristics of college towns:

  1. Mixed-Use Zoning: Cities with colleges and universities often employ mixed-use zoning strategies to encourage a vibrant and diverse urban environment. This zoning approach allows for a combination of residential, commercial, and institutional uses within the same area, fostering a sense of community and facilitating interactions between students, faculty, and residents.
  2. Height and Density Restrictions: Due to the presence of educational institutions, cities may have specific regulations on building height and density to ensure compatibility with the surrounding neighborhoods and maintain the character of the area. These restrictions help balance the need for development with the preservation of the existing urban fabric.
  3. Student Housing: Cities with colleges and universities may have regulations or guidelines for student housing to ensure an adequate supply of affordable and safe accommodations for students. This can
    include requirements for minimum bedroom sizes, occupancy limits, and proximity to campus.
  4. Parking and Transportation: Given the concentration of students, faculty, and staff, parking and transportation considerations are crucial. Cities may require educational institutions to provide parking facilities or implement transportation demand management strategies, such as promoting public transit use, cycling infrastructure, and pedestrian-friendly designs.
  5. Community Engagement: Some cities encourage colleges and universities to engage with the local community through formalized agreements or community benefit plans. These may include commitments to support local businesses, contribute to neighborhood improvement projects, or provide educational and cultural resources to residents.

  1. Reed v. Town of Gilbert (2015): This Supreme Court case involved a challenge to the town of Gilbert, Arizona’s sign code, which regulated the size, location, and duration of signs based on their content. The court held that the sign code was a content-based restriction on speech and therefore subject to strict scrutiny.
  2. City of Ladue v. Gilleo (1994): In this Supreme Court case, the court struck down a municipal ordinance that banned the display of signs on residential property, except for signs that fell within specific exemptions. The court held that the ban was an unconstitutional restriction on the freedom of speech.
  3. Metromedia, Inc. v. San Diego (1981): This Supreme Court case involved a challenge to a San Diego ordinance that banned off-premises advertising signs while allowing on-premises signs. The court held that the ordinance was an unconstitutional restriction on free speech, as it discriminated against certain types of speech.
  4. City of Ladue v. Center for the Study of Responsive Law, Inc. (1980): In this Supreme Court case, the court upheld a municipal ordinance that prohibited the display of signs on public property, but only if the signs were posted for longer than 10 days. The court held that the ordinance was a valid time, place, and manner restriction on speech.
  5. City of Boerne v. Flores (1997): This Supreme Court case involved a challenge to a municipal sign code that regulated the size, location, and content of signs in the city. The court held that the sign code violated the Religious Freedom Restoration Act, as it burdened the exercise of religion without a compelling government interest.
