The choice of red, white, and blue in national flags often carries historical, cultural, and political significance. Here are some reasons why various nations have chosen these colors:

  1. Historical Connections:
    • United States: The colors were chosen for their flag in 1777 and have been interpreted to symbolize valor (red), purity (white), and justice (blue). The colors were influenced by the British Union Jack.
    • France: The Tricolour flag adopted during the French Revolution represents liberty (blue), equality (white), and fraternity (red).
    • United Kingdom: The Union Jack combines elements from the flags of England (red and white), Scotland (blue and white), and Ireland (red and white).
  2. Cultural and Political Significance:
    • Russia: The flag’s colors were adopted from the Dutch flag, symbolizing pan-Slavism (red for bravery, blue for faithfulness, and white for honesty).
    • Netherlands: The Dutch flag’s colors (originally derived from the Prince’s Flag) have historical roots, symbolizing the struggle for independence and liberty.
    • Czech Republic and Slovakia: Both countries use red, white, and blue to represent their Slavic heritage.
  3. Influence and Inspiration:
    • Chile, Costa Rica, and Panama: These countries were influenced by the colors and symbolism of other flags (e.g., the French and American flags) during their independence movements.
    • Australia and New Zealand: Both countries incorporate the Union Jack in their flags, reflecting their colonial history with the United Kingdom.
  4. Symbolism:
    • Croatia, Serbia, and Slovenia: The colors are traditional pan-Slavic colors, representing freedom and national unity.
    • Iceland and Norway: The colors reflect their historical and cultural ties to other Scandinavian countries.

The exact reasons can vary, but often the colors reflect a mix of historical alliances, cultural heritage, and political ideals.

The term “lively arts” is attributed to American writer and poet James Thurber. It was popularized in the mid-20th century as a way to describe various forms of performing arts, such as theater, dance, music, and other creative expressions.

“What art is, in reality, is this missing link,  not the links which exist.

It’s not what you see that is art; art is the gap”

— Marcel Duchamp

 

Today we refresh our understanding of the literature that guides the safety and sustainability goals of lively art events in educational settlements.  Consortia have evolved quickly in recent years, leading and lagging changes in the content creation and delivery domain.  With this evolution a professional discipline has emerged that requires training and certification in the electrotechnologies that contribute to “event safety”; among them:

ASHRAE International

Standard 62.1: This standard establishes minimum ventilation rates and indoor air quality requirements for commercial buildings, including theaters and auditoriums.

Standard 55: This standard specifies thermal comfort conditions for occupants in indoor environments, which can have an impact on air quality.

RP-16-17 Lighting for Theatrical Productions: This standard provides guidance on the design and implementation of lighting systems for theatrical productions. It includes information on the use of color, light direction, and light intensity to create different moods and effects.

RP-30-15 Recommended Practice for the Design of Theatres and Auditoriums: This standard provides guidance on the design of theaters and auditoriums, including lighting systems. It covers topics such as seating layout, stage design, and acoustics, as well as lighting design considerations.

DG-24-19 Design Guide for Color and Illumination: This guide provides information on the use of color in lighting design, including color temperature, color rendering, and color mixing. It is relevant to theater lighting design as well as other applications.

“Immoderate Greatness: Why Civilizations Fail, and Apologies to the Grandchildren” | William Ophuls

…”Your children are not your children.
They are the sons and daughters of Life’s longing for itself.
They come through you but not from you,
And though they are with you yet they belong not to you.
You may give them your love but not your thoughts,
For they have their own thoughts.
You may house their bodies but not their souls,
For their souls dwell in the house of tomorrow,
which you cannot visit, not even in your dreams…”

Global Positioning System: A Generation of Service to the World

Citizens of the Earth depend upon United States leadership in this technology for several reasons:

Development: The GPS was originally developed by the US Department of Defense for military purposes, but it was later made available for civilian use. The US has invested heavily in the development and maintenance of the system, which has contributed to its leadership in this area.

Coverage: The GPS provides global coverage, with 24 satellites orbiting the earth and transmitting signals that can be received by GPS receivers anywhere in the world. This level of coverage is unmatched by any other global navigation system.

Accuracy: The US has worked to continually improve the accuracy of the GPS, with current accuracy levels estimated at around 10 meters for civilian users and even higher accuracy for military users.

Innovation: The US has continued to innovate and expand the capabilities of the GPS over time, with newer versions of the system including features such as higher accuracy, improved anti-jamming capabilities, and the ability to operate in more challenging environments such as indoors or in urban canyons.

Collaboration: The US has collaborated with other countries to expand the reach and capabilities of the GPS, such as through the development of compatible navigation systems like the European Union’s Galileo system and Japan’s QZSS system.

United States leadership in the GPS has been driven by a combination of investment, innovation, collaboration, and a commitment to improving the accuracy and capabilities of the system over time.

Hosting open-air celebrations such as graduations and cultural requires sensitivity to audio standards that ensure high-quality sound and audience safety.  Today at the usual hour we examine the standards covering sound system design, noise control, loudness levels, equipment specifications, weather and local environmental considerations.
Surprisingly, there are many even without approaching the not insignificant cabling system standards.  We pick three representatives titles which cross reference one another:

 

World Health Organization recommendations for limiting exposure to leisure noise (e.g., concerts) to a level exceeding 80 dBA for 24 hours or 140 dB peak sound pressure to prevent hearing loss.  Recommendations for speech heavy events will defer from musical events.

 

Audio Engineering Society Guideline AES56-2008 which provides recommendations for loudspeaker placement in sound reinforcement systems.  Key points include:

    • Height and Angle: Line array speakers are often elevated (e.g., on trusses or poles) and angled to cover the audience while reducing sound spill to non-audience areas.
    • Distance: Main speakers should be placed to avoid excessive sound pressure near the front (e.g., 95–100 dBA max for audience safety) and ensure clarity at the back.

Acoustical Society of America ASA-2010 Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools.  While primarily for schools, this standard’s principles can apply to open-air educational or community events, emphasizing background noise control and speech intelligibility.  For open-air audiences at events like outdoor lectures or festivals, speaker placement should minimize interference from environmental noise (e.g., traffic, wind). The standard suggests maintaining a signal-to-noise ratio where speech is at least 15 dB above background noise for clarity.

Standards Indiana § Greenwood

“Center Grove Schools enters the 2022/2023 school year with a new high-tech safety partner — Centegix CrisisAlert — purchased in part with school safety grant money that pairs with their Emergency Operations Center that opened in January 2022.  The CrisisAlert program  puts security at the fingertips of all teachers and staff.

Both systems address what the district learned it had to work on from a school safety assessment back in 2018 – live monitoring and faster response times in an emergency.   Seven-hundred cameras will scan every school in real-time from the district’s Emergency Operations Center. — More”
