The French press is a popular device for brewing coffee, comprising a cylindrical beaker—or “jug”—fitted with a lid and plunger with a fine wire mesh filter. The plunger is used to drive the solid coffee particles to the bottom of the jug, separating these grounds from hot liquid above. When using the French press in this way, a growing permeable pack of ground coffee is pushed through hot water by applying force to the plunger. We use a combination of kitchen-based and laboratory experiments to determine the force required to push on the plunger as a function of the speed of the plunger and the mass of coffee used. We calculate that for the recommended preparation method, the maximum force is 32 N to complete the pressing action in 50 s. We propose that home coffee preparation provides a fun, low-cost, and relatable learning opportunity for students and for those who are interested in coffee science.

The Lake Isle of Innisfree

I will arise and go now, and go to Innisfree,
And a small cabin build there, of clay and wattles made;
Nine bean-rows will I have there, a hive for the honey-bee,
And live alone in the bee-loud glade.
And I shall have some peace there, for peace comes dropping slow,
Dropping from the veils of the morning to where the cricket sings;
There midnight’s all a glimmer, and noon a purple glow,
And evening full of the linnet’s wings.
I will arise and go now, for always night and day
I hear lake water lapping with low sounds by the shore;
While I stand on the roadway, or on the pavements grey,

I hear it in the deep heart’s core.

— William Butler Yeats

Today we walk through literature governing the safety and sustainability of the open space features of education community estates.   Unlike the titles for the building envelope, which are known to most design professionals and contractors, the standards for grounds and landscaping are widely scattered; many of them occupational safety related; created, administered and enforced by units of government.

Bucolia 100.  We present a broad overview of the dominant standards catalogs incorporated by reference into public safety and sustainability legislation.

Bucolia 200.  We drill into technical specifics of the titles in Bucolia 100.

Bucolia 400.  We pick through case studies in landscape, garden, tree and water literature.  We also track titles about the reclamation of building roofs for permeable surfaces and gardens.

During the winter months (Bucolia 200) in the northern hemisphere we include snow and ice management; while covering summer month technologies for southern hemisphere (and vice-versa).  Snowfalls in the southern hemisphere are mainly contained to the highlands and mountain ranges, which are almost exclusively in Victoria and Southern New South Wales, as well as the mountains in Tasmania.   Winter does not pose as much of a cost burden to education facilities in the southern hemisphere as it does in the northern hemisphere.

Landscape standards refer to guidelines or regulations that specify the requirements for the design, installation, and maintenance of outdoor spaces such as parks, gardens, streetscapes, and public spaces. Landscape standards typically cover various aspects of landscape design, including vegetation selection, planting arrangements, irrigation systems, hardscape materials, and lighting.

These standards may be set by government agencies at the federal, state, or local level, or by professional organizations such as the American Society of Landscape Architects (ASLA). Landscape standards aim to ensure that outdoor spaces are safe, functional, and aesthetically pleasing while also promoting sustainability and environmental protection.

Landscape standards may also address issues such as accessibility for people with disabilities, water conservation, stormwater management, and erosion control. They may vary depending on the specific location, climate, and intended use of the outdoor space. Compliance with landscape standards may be required for approval of development projects, public funding, or other permits.

“The Boys in the Boat”

The Boys in the Boat is a true story based on the struggles and sacrifices made by the University of Washington rowing team to compete at rowing at the 1936 Summer Olympics – Men’s eight.

Joseph Sutton-Holcomb from The Seattle Times writes that author Daniel James Brown got the idea to write this book when his neighbor Judy Willman said that her father, Joe Rantz, was a fan of his works and wanted to have a conversation with the author. That conversation with Joe Rantz about life during the Great Depression led to an in-depth chat about his time as a rower at the University of Washington.

Standards for a Kitchen Symphony | November/December 2024

ASTM International (formerly known as the American Society for Testing and Materials) is a globally recognized organization that develops and publishes technical standards for a wide range of products, systems, and services. These standards are used by manufacturers, regulatory bodies, and other stakeholders to ensure that products and services are safe, reliable, and of high quality.

In the field of measurement science, ASTM plays an important role in developing standards and guidelines for measurement techniques and practices. These standards cover a wide range of topics related to measurement science, including the calibration of instruments, the characterization of measurement systems, and the validation of measurement results. They are used by researchers, engineers, and other professionals in academia, industry, and government to ensure that measurements are accurate, precise, and reliable.

ANSI Public Review

 

ASTM standards for measurement science are developed through a process that involves input from experts in the field, including researchers, industry professionals, and regulatory bodies. These standards are updated regularly to reflect advances in measurement science and technology, as well as changes in industry and regulatory requirements.  This is a far better way to discover and promulgate leading practice.  In fact, there are regulations intended to restrain the outsized influence of vertical incumbents in legislative precincts where market-making happens.

The Best Breakdown of America You’ve Never Heard: Richard Miniter

In Federalist No. 2, John Jay [1764 Graduate of King’s College; now Columbia University] argues that a strong union under the Constitution will promote peace and prosperity, which are conducive to the spread of religion and morality:

“Providence has been pleased to give this one connected country to one united people—a people descended from the same ancestors, speaking the same language, professing the same religion, attached to the same principles of government, very similar in their manners and customs… These considerations, and many others that might be mentioned, prove, and experience confirms it, that artificial distinctions and separations of [America’s] land are essentially unnatural; and that they may be eradicated and extirpated by the united and advisable efforts of individuals and communities…”

The Federalist Papers discuss themes of morality, social order, and the importance of a cohesive society, they do not explicitly emphasize the importance of Christian faith to the American constitutional republic.  The authors generally focused on principles of governance, political theory, and the structure of the proposed Constitution.

Harvard’s Memorial Chapel, also known as Memorial Church, was designed by the architectural firm Coolidge, Shepley, Bulfinch, and Abbott. The church was dedicated on Armistice Day, November 11, 1932, as a memorial to Harvard alumni who died in World War I.
