The bookwheel, also known as a revolving bookcase, was invented by an Italian scholar and polymath named Agostino Ramelli. Ramelli was born in 1531 in Ponte Tresa, a town in present-day Italy, and he lived during the Renaissance period.

Ramelli’s invention, described in his work titled “Le diverse et artificiose machine del capitano Agostino Ramelli” (The Various and Ingenious Machines of Captain Agostino Ramelli), was published in 1588. This book showcased a collection of 195 mechanical devices.  

Ramelli’s work contributed to the growing interest in mechanical inventions during the Renaissance period. His bookwheel design remains a fascinating example of early engineering and ingenuity, highlighting the desire for knowledge and practical solutions in the pursuit of learning and scholarly endeavors.

“Bookwheel” Early Data Center

The standard of care for wiring safety for data centers —  a continually expanding presence in education communities even before the pandemic  — is established in National Electrical Code Articles 645 (Information Technology Equipment), Article 646 (Modular Data Centers) and Article 647 (Sensitive Electronic Equipment).   You will notice that these articles cover the topic comprehensively and bear the imprint of competing Producer-Interest groups.  There are no User-Interest representatives on Code-Making Panel 12 that represent the final fiduciary in education communities even though education communities are one of the largest markets for information and communication technology systems.

The current version of NFPA 70 is linked below:

Transcripts  of technical committee action during the 2026 revision (CMP-16) are linked below because they will inform our recommendations for the 2026 National Electrical Code.  Keep in mind that the Technical Correlating Committee is moving content around the Code in order to make the NEC easier to use by experts.

We will use these in our exploration of what we might propose for improvements in the 2026 revision.  Public comment on the First Draft of the 2026 Edition will be received until August 28th.

The issues that have been in play in these articles of the NEC are familiar to veterans of the “food fight” – occupancy classification, cable specifications, fire protection, ventilation, energy consumption, surge protection, licensing of engineers. etc.  We look for market-making excesses by opposing stakeholders that seek to limit their risk while raising the (financial) risk to education communities.

We encourage our colleagues to participate in the NFPA code development process directly.  We also encourage stakeholders in education communities — students, faculty and staff  to join us during any of the teleconferences we co-host with the IEEE Education & Healthcare Facilities Committee 4 times monthly in both European and American time zones.   See our CALENDAR for the next online meeting.

Here we shift our perspective 120 degrees to understand the point of view of the Producer interest in the American national standards system (See ANSI Essential Requirements).  The title of this post draws from the location of US and European headquarters.  We list proposals by a successful electrical manufacturer for discussion during today’s colloquium:

2026 National Electrical Code

CMP-1: short circuit current ratings, connections with copper cladded aluminum conductors, maintenance to be provided by OEM, field markings

CMP-2: reconditioned equipment, receptacles in accessory buildings, GFCI & AFCI protection, outlet placement generally, outlets for outdoor HVAC equipment(1)

(1) Here we would argue that if a pad mount HVAC unit needs service with tools that need AC power once every 5-10 years then the dedicated branch circuit is not needed.  Many campuses have on-site, full-time staff that can service outdoor pad mounted HVAC equipment without needing a nearby outlet.  One crew — two electricians — will run about $2500 per day to do anything on campus.

CMP-3: No proposals

CMP-4: solar voltaic systems (1)

(1) Seems reasonable – spillover outdoor night time lighting effect upon solar panel charging should be identified.

CMP-5: Administrative changes only

CMP-6: No proposals

CMP-7: Distinction between “repair” and “servicing”

CMP-8: Reconditioned equipment

CMP-9: Reconditioned equipment

CMP-10: Short circuit ratings, service disconnect, disconnect for meters, transformer secondary conductor, secondary conductor taps, surge protective devices, disconnecting means generally, spliced and tap conductors, more metering safety, 1200 ampere threshold for arc reduction technology, reconditioned surge equipment shall not be permitted, switchboard short circuit ratings

CMP-12: Lorem

“Europe today has little desire to reproduce itself,
fight for itself or even take its own side in a argument.
By the end of the lifespans of most people currently alive,
Europe will not be Europe and the peoples of Europe
will have lost the only place in the world we had to call home”

– Douglas Murry (“The Strange Death of Europe”)

Large European universities such as Rijksuniversiteit Groningen are integrated into the fabric of the surrounding city. There are several ways in which this integration takes place:

Physical location: Many European universities are located in the heart of the city, often in historic buildings that have been repurposed for educational use. This central location means that the university is easily accessible to students and the general public, and that it is often surrounded by other cultural institutions, such as museums, theaters, and libraries.

Student life: The presence of a large student population can have a significant impact on the city’s culture and economy. Many European cities have developed a vibrant student culture, with cafes, bars, and other venues catering to the needs and interests of young people. This can help to create a sense of community between the university and the city, and can also bring economic benefits to local businesses.

Facilities Organization

Research and innovation: Large European universities are often at the forefront of research and innovation, and they can be important drivers of economic growth in the surrounding region. Many universities work closely with local businesses and industries, and they may also collaborate with other universities and research institutions in the area.

Cultural exchange: Universities can be important centers of cultural exchange, both for international students and for local residents. Many European universities offer language classes and other cultural programs that are open to the public, and they may also host lectures, concerts, and other events that are designed to promote cross-cultural understanding.

Overall, the integration of large European universities into the city is a complex and multifaceted process that can have a significant impact on the social, cultural, and economic life of the surrounding region.

The origin of brown cafés can be traced back to the 17th century, during the Dutch Golden Age. At that time, the Netherlands was a prosperous and influential trading nation, and Amsterdam was a bustling city with a thriving port. Sailors, merchants, and locals needed places to socialize, relax, and conduct business, leading to the emergence of taverns and pubs.

The term “brown café” is believed to have originated from the brownish stains that formed on the walls and ceilings due to tobacco smoke, candle soot, and other atmospheric elements. These stains gave the cafés a distinct, cozy ambiance and a sense of history.

Brown cafés became an integral part of Dutch culture, serving as communal gathering spots for people of all walks of life. They were places where locals would meet friends, engage in conversations, enjoy a drink, and sometimes play board games like chess or backgammon. Over time, brown cafés became associated with an authentic, unpretentious, and relaxed atmosphere, attracting both locals and tourists.

The unique charm of brown cafés lies in their preserved historical interiors, with old wooden furniture, dim lighting, and a wide selection of local beers and spirits. Many brown cafés still retain their original character, transporting visitors back in time and providing a cozy retreat from the hustle and bustle of modern life.

While the concept of brown cafés originated in the Netherlands, similar types of establishments can also be found in other European countries, such as Belgium and parts of Germany. However, the term “brown café” is primarily associated with the Dutch tradition of cozy, atmospheric, and convivial drinking establishments.

This facility class has many names but is similar in our approach to them: the settings that provide primary care in a visible, central service.  After the chapel, the library, the kitchen and the classroom, the on-campus medical center is a central fixture.  These clinics typically provide basic medical services primarily aimed at addressing the immediate health needs of students and sometimes staff.   These clinics are often staffed by a nurse or a small team of healthcare professionals such as nurse practitioners or physician assistants.

  • Services may include first aid, basic medical care (such as treating minor injuries and illnesses), immunizations, health screenings, and sometimes mental health counseling.
  • These clinics are often staffed by a nurse or a small team of healthcare professionals such as nurse practitioners or physician assistants. In some cases, a physician may be available on a part-time basis.
  • These clinics are usually small and may be located within or near the school premises. They typically have limited space and equipment compared to hospitals.

Access to school-based clinics is often limited to students and staff during school hours. They may not be open during weekends, holidays, or outside of regular school hours.
