"The environment we live in is a 3 dimensional Rorschach test"
How does the environment affect our minds?
How does our psyche shape the environment?
What psychological and biological factors are responsible for our sense of aesthetic?
Inspired by my conversations with Ar. Jaisim, and by the superb book, "The Architecture of Happiness" by Alain De Botton, this presentation explores the interface between psychology and architecture.

Study of Folded Plates for understanding their use, types, technology along with suitable case studies. This is a specific type of Methodology adopted for construction over long spans column free spaces. How structurally Folded plates surpases the need of column grids and conventional methods of construction with the proper design and technology is the motive of this study.
The tube is the name given to the systems where in order to resist lateral loads (wind, seismic, etc.) a building is designed to act like a three-dimensional hollow tube. The system was introduced by Fazlur Rahman Khan while at Skidmore, Owings and Merrill's (SOM) Chicago office. The first example of the tube’s use is the 43-story Khan-designed DeWitt-Chestnut Apartment Building in Chicago, Illinois, completed in 1963.
The system can be constructed using steel, concrete, or composite construction (the discrete use of both steel and concrete). It can be used for office, apartment and mixed-use buildings. Most buildings in excess of 40 stories constructed in the United States since the 1960s are of this structural type. The tube system concept is based on the idea that a building can be designed to resist lateral loads by designing it as a hollow cantilever perpendicular to the ground.
In the simplest incarnation of the tube, the perimeter of the exterior consists of closely spaced columns that are tied together with deep beams through moment connections. This assembly of columns and beams forms a rigid frame that amounts to a dense and strong structural wall along the exterior of the building.
This exterior framing is designed sufficiently strong to resist all lateral loads on the building, thereby allowing the interior of the building to be simply framed for gravity loads. Interior columns are comparatively few and located at the core.
The distance between the exterior and the core frames is spanned with beams or trusses. This maximizes the effectiveness of the perimeter tube by transferring some of the gravity loads within the structure to it and increases its ability to resist overturning due to lateral loads.
Since 1963, a new structural system of framed tubes appeared in skyscraper design and construction.
Fazlur Khan defined the framed tube structure as "a three dimensional space structure composed of three, four, or possibly more frames, braced frames, or shear walls, joined at or near their edges to form a vertical tube-like structural system capable of resisting lateral forces in any direction by cantilevering from the foundation."Closely spaced interconnected exterior columns form the tube. Horizontal loads, for example wind, are supported by the structure as a whole. About half the exterior surface is available for windows. Framed tubes allow fewer interior columns, and so create more usable floor space. Where larger openings like garage doors are required, the tube frame must be interrupted, with transfer girders used to maintain structural integrity.
The first building to apply the tube-frame construction was the DeWitt-Chestnut apartment building which Khan designed(1963) and was completed in Chicago by 1965. This laid the foundations for the tube structures of many other later skyscrapers, including his own John Hancock Center and Willis Tower, and can been seen in the construction of the World Trade Cente

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. SPACE FRAMES AND GEODESIC
DOMES
Objectives:
1. the concepts of point, line, plane and dimensions in
relationship to the triangle.
2. Understand the basic structural engineering concepts
that underlie geodesic dome construction;
3. Understand the advantages and disadvantages of
modern building materials in dome construction; and
4. Have an increased awareness of more in-depth
concepts relating to the study of architecture,
geometry, and structures.
3. Special Words
• A polyhedron (many surfaces) is a geometric
solid in three dimensions with flat faces and
straight edges.
• A tetrahedron is a polyhedron with four sides,
but is also called a pyramid.
• A hexahedron is a polyhedron with six sides, but
is also called a cube.
• A polyhedron with six rectangles as sides also
has many names—a rectangular parallelepided,
rectangular prism, or box.
• An octahedron is a polyhedron with eight faces.
4. Vocabulary
• Tension is a force that acts to expand or
lengthen the thing it is acting on.
• Compression is a force that acts to compress
or shorten the thing it is acting on.
7. SPACE FRAMES
• A space frame is a truss-like, lightweight rigid
structure constructed from interlocking struts
in a geometric pattern.
8. SPACE FRAMES
• Space frames or Space structure usually
utilize a multidirectional span, and are often
used to accomplish long spans with few
9. SPACE FRAMES
• They derive their strength from the inherent
rigidity of the triangular frame; flexing loads
(bending moments) are transmitted as tension
and compression loads along the length of
each strut.
11. • Space frames or Space structure are an
increasingly common architectural technique
especially for large roof spans in modernist
commercial and industrial buildings
12. Some space frame applications
include:
• Hotel/Hospital/commercial building
entrances
• Commercial building lobbies/atriums
• Parking canopies
13. Advantages of space frame systems over
conventional systems:
Random column placement
Column-free spaces
Minimal perimeter support
Controlled load distribution
Design freedom
Supports all types of roofing
14. GEODESIC DOMES
• A geodesic dome is a sphere-like structure
composed of a complex network of triangles.
15. GEODESIC DOMES
• Geodesic domes are usually
hemispheres (parts of spheres, like
half a ball) made up of triangles. The
triangles have 3 parts:
–the face - the part in the middle
–the edge - the line between corners
–the vertex - where the edges meet
16. The triangles create a self-bracing
framework that gives structural
strength while using a minimum of
material.
21. A dome’s design is dependent upon
many factors, including:
• Needed area and span, or distance between
supports;
• Budget and building schedule;
• Architect’s and /or client’s aesthetic
preferences;
• Forces, such as compression and tension,
acting on the structure; and
• Building materials.
22. EXAMPLES OF GEODESIC DOMES:
Spaceship Earth, the AT&T Pavilion at Epcot in
Disney World, Florida, is an adaptation of
Buckminster Fuller's geodesic dome
Tacoma Dome in Washington State
Milwaukee's Mitchell Park Conservatory
Biosphere desert project in Arizona
Des Moines Arboretum, a self contained
ecosphere
23. Engineering Disasters
Engineers must be concerned about safety at all times.
Lives are at stake when bridges, buildings, or structures
collapse. Engineers must design structures to withstand
all kinds of weather conditions and all types of loads.
While the goal is to have no design fail, engineers
examine and learn from past mistakes to avoid such
failures in the future.
