The World Soil Museum hosts a range of educational programs and workshops for students, researchers, and other visitors who are interested in learning more about soil science. These programs cover topics such as soil classification, soil management, and soil conservation, and they are designed to help people understand the vital role that soils play in supporting agriculture, ecosystems, and human societies around the world.
Geothermal systems cool buildings by leveraging the stable temperatures found beneath the Earth’s surface. A geothermal heat pump system consists of a ground loop, heat exchanger, and distribution system.
In cooling mode, the system extracts heat from the building and transfers it to the ground. The ground loop, typically composed of pipes buried horizontally or vertically, circulates a fluid that absorbs heat from the building’s interior. The fluid, warmed by this process, is then pumped through the ground loop where the Earth’s cooler temperatures absorb the heat, effectively dissipating it into the ground.
The cooled fluid returns to the heat pump, which distributes the now-cooler air throughout the building via the distribution system, such as ductwork. This process is highly efficient because the ground maintains a relatively constant temperature year-round, allowing the geothermal system to operate with less energy compared to traditional air-source cooling methods.
At the moment, though the technology has been made practical since Prince Piero Ginori Conti’s discovery in 1904, and has since tracked well in local building codes and environmental regulations, the bibliography for earth energy systems is nascent and relatively thin. One trade association is emerging from the gathering pace of applications and case studies: Closed-Loop/Geothermal Heat Pump Systems Design and Installation Standards

When the wicked problems of peace and economic inequality cannot be solved, political leaders, and the battalions of servile administrative muckety-mucks who report to them, resort to fear-mongering about an imagined problem to be solved centuries hence assuming every other nation agrees on remedies of its anthropogenic origin. We would not draw attention to it were it not that large tranches of the global academic community are in on the grift costing hundreds of billions in square-footage for research and teaching hopelessness to our children and hatred of climate change deniers.
Before the internet is scrubbed of information contrary to climate change mania, we recommend a few titles:
“There’s a new coffee shop in Cleveland, and it’s in John Marshall High School. The “Lawyers Café” serves lattes, healthy fruit smoothies, and Rising Star coffee, and it’s completely student-run. While they brew up the drinks as baristas and handle the budgets on the finance team, all of the scholars are getting hands-on job skills and learning what it takes to run their own small business.”
“In those vernal seasons of the year, when the air is calm and pleasant, it were an injury and sullenness against Nature not to go out, and see her riches, and partake in her rejoicing with heaven and earth.”
— John Milton, Tractate of Education
President George H. Bush’s prescient warning to graduates about the destabilizing dangers of “political correctness” to the American experiment in a constitutional republic. Escalated by the presidencies of Barack Obama and Joseph Biden; accelerated by multinational social media conglomerates, free speech — globally — remains challenged and threatens the return to the tribalism that doomed ancient civilizations. Higher education in America will have the heaviest hand in this transformation.
“Ironically, on the 200th anniversary of our Bill of Rights, we find free speech under assault throughout the United States, including on some college campuses. The notion of political correctness has ignited controversy across the land. And although the movement arises from the laudable desire to sweep away the debris of racism and sexism and hatred, it replaces old prejudice with new ones. It declares certain topics off-limits, certain expression off-limits, even certain gestures off-limits.”
Square D was founded in 1902 in Detroit, Michigan, by Bryson Dexter Horton and James B. McCarthy as McBride Manufacturing Company, focusing on electrical fuses. By 1908, it became Detroit Fuse and Manufacturing, adopting the iconic “Square D” logo—a “D” in a square—reflecting its Detroit roots.
Renamed Square D in 1917, the company pioneered safety switches and circuit breakers, growing significantly with 18,500 employees and $1.65 billion in sales by 1991. That year, after a competitive 10-week bidding process, French multinational Groupe Schneider S.A. acquired Square D for $2.23 billion, raising its offer from $1.96 billion to $88 per share.
The acquisition, approved by Square D’s board and the U.S. Justice Department, made Schneider Electric the world’s largest electrical distribution equipment manufacturer, integrating Square D’s innovative products into its global energy management portfolio.
ANSI’s 2025/2026 Student Paper Competition challenges high school & college students to investigate the invisible standards that keep our world running—from smartphone compatibility to food safety.
For nearly twenty years now, the American National Standards Institute Committee on Education administers a student paper competition intended to encourage understanding of the global standards system that also provides a solid prize — in the $1000 to $5000 range. The topic of the 2024 Student Paper Competition will be What Role Do or Could Standards Play in Safe and Effective Implementation of Artificial Intelligence Applications/Systems?
For the past six years Standards Michigan has hosted Saturday morning workshops to help students (and faculty) interested in entering the contest. We will soon post those dates on our CALENDER. We typically host them — three sessions ahead of the deadline — on Saturday mornings.
We provide links to previous paper winners and refer you to Lisa Rajchel: lrajchel@ansi.org for all other details.

US academia has increasingly mirrored the dystopian control mechanisms in George Orwell’s 1984, particularly through the lens of Critical Race Theory (CRT) and its extensions into Diversity, Equity, and Inclusion (DEI) frameworks.
In Orwell’s novel, the Party enforces ideological conformity via Newspeak (a restricted language that limits thought), doublethink (holding contradictory beliefs), thoughtcrime (punishing unapproved ideas), and the rewriting of history to serve power.
CRT posits that racism is embedded in the structure of Western institutions. It rejects colorblindness and meritocracy as tools of “white supremacy,” framing individuals primarily by racial identity — oppressors versus the oppressed. In universities, this has evolved into mandatory trainings, curricula, and loyalty tests that prioritize “equity” (equal outcomes by group) over equality of opportunity.
Key Orwellian parallels include:
Language control resembling Newspeak: terms like “systemic racism,” “white fragility,” “microaggressions,” and “anti-racism” redefine reality so that disagreement signals complicity in oppression.
Doublethink: universities champion “diversity” while enforcing ideological uniformity, claiming to fight oppression while stigmatizing dissent as violence.
Thoughtcrime via cancel culture: surveys show high rates of self-censorship, with dissenting scholars facing social ostracism, investigations, or professional consequences.
History is reframed — America’s founding reduced to perpetual racial hierarchy — echoing the Ministry of Truth. Standpoint epistemology elevates “lived experience” of favored groups over empirical evidence and universal reason.
This agenda undermines academia’s core purpose: the pursuit of truth through open debate and evidence. Instead of rigorous inquiry, power — framed as “punching up” — dictates acceptable thought, eroding liberal education’s commitment to individualism and free expression.
…”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,
Outdoor play facilities for school children are governed by several key codes and standards to ensure safety and accessibility. The European Standard EN 1176 outlines safety requirements for playground equipment, covering design, installation, and maintenance to minimize risks like entrapment and falls.
The Health and Safety at Work etc. Act 1974 mandates risk assessments and safe environments, while the Occupiers’ Liability Act 1957 (revised 1984) ensures playgrounds are reasonably safe for users.
The Consumer Protection Act 1987 holds manufacturers liable for defective equipment. The Children Act 1989 requires facilities to be suitable and safe. Ofsted emphasizes stimulating, inclusive, and varied play environments that promote physical and mental health, encouraging year-round outdoor learning. Compliance with these standards, alongside regular inspections (e.g., TÜV certification), ensures safe, durable, and engaging playgrounds that foster children’s development while minimizing injury risks.
Today at the usual hour we update our understanding of the technical literature that supports making these facilities safe, sustainable and enjoyable. Use the login credentials at the upper right of our home page.
