Beauty, Memory, Unity : A Theory of Proportion in Architecture
Ancient architects and artists had a way of striking resonant chords in the viewers of their work.This book points to a possible way of returning a sense of unity to the visual arts through a combination of theoretical ideas and practical methods, of narrative description and visual exercises. Proportion, the use of number and geometry as design tools, is seen in the context of the search for the beautiful.From the theoretic, symbolic mathematics of the Pythagoreans, Platonists, and Neo-Platonists, the book proposes an aesthetic theory, a way of approaching beauty, rooted in the idea of psyche and expressed through the ancient sciences of arithmetic, geometry, music, and astronomy.Topics treated include: an explanation of the concept of symbolic or qualitative number; an introduction to Pythagorean and Platonic numerical philosophy; the nature of beauty and its relation to number; the derivation of the ancient musical octave; the Golden Section, its mathematics, geometry, and relation to philosophy, particularly its role as a geometrical logos; and the connection of these ideas to the numerical-geometrical canons of classical architecture.These concepts are illustrated step by step as applied to the elements and archetypal compositions of classical architecture, such as the order and portico, using arithmetic, geometric, and harmonic ratio methods. The proportional idea is illustrated with reconstructions of exemplary buildings based on the methods described, following through the historical periods of Egypt, Greece, Rome, the Middle ages, the Italian Renaissance, and the Enlightenment.Though the book is focused on architecture, the methods presented may be used by artists and designers in any visual field.The book suggests several pathways on which contemporary designers might move toward creating a sane and beautiful world through a merger of art and science.

Geometry of Design 2nd Ed : Studies in Proportion and Composition
At last, a mathematical explanation of how art works presented in a manner we can all understand.Kimberly Elam takes the reader on a geometrical journey, lending insight and coherence to the design process by exploring the visual relationships that have foundations in mathematics as well as the essential qualities of life. Geometry of Design takes a close look at a broad range of twentieth-century examples of design, architecture and illustration (from the Barcelona chair to the paintings of Georges Seurat, from the Braun hand blender to the Conico kettle), revealing underlying geometric structures in their compositions.Explanations and techniques of visual analysis make the inherent mathematical relationships evident and a must-have for anyone involved in art, design, or architecture graphic arts. The book focuses not only on the classic systems of proportioning, such as the golden section and root rectangles, but also on less well known proportioning systems such as the Fibonacci Series.Through detailed diagrams these geometric systems are brought to life giving an effective insight into the design process.

What is the proportion of mathematics in the dual study program Tourism Management?
In the dual study program Tourism Management, the proportion of mathematics is typically around 10-20% of the overall curriculum. Mathematics is an important component in this program as it helps students develop analytical and problem-solving skills necessary for various aspects of the tourism industry, such as data analysis, financial management, and pricing strategies. While the focus of the program is on tourism management, a solid foundation in mathematics is essential for students to succeed in their studies and future careers in the field.

Is my proportion correct?
To determine if your proportion is correct, you should compare it to a known or expected value. If your proportion matches the expected value or falls within an acceptable range, then it is likely correct. You can also use statistical tests to assess the significance of your proportion. Additionally, double-check your calculations and ensure that your sample size is appropriate for making accurate inferences.

What are proportion equations?
Proportion equations are mathematical expressions that show the equality of two ratios. They are used to compare the relationship between two sets of numbers or quantities. In a proportion equation, the cross products of the ratios are equal, meaning that the product of the first term in one ratio and the second term in the other ratio is equal to the product of the second term in the first ratio and the first term in the second ratio. Proportion equations are commonly used in various real-life situations, such as in cooking recipes, financial calculations, and solving problems involving similar figures.
-
What are proportion problems?
Proportion problems involve comparing two ratios or fractions to determine if they are equal. These problems often involve finding an unknown quantity in a given proportion. Proportion problems can be solved using cross multiplication or by setting up equivalent fractions. They are commonly used in various real-life situations such as cooking, finance, and geometry.

Hans van der Laan’s Instruments of Thought : Proportion, Architecture, Analogy
The work of the Dutch Benedictine monk and architect Hans van der Laan (1904–1991) offers important insights into the ways in which artifacts address the complexity of human physical, cognitive, and social needs.Van der Laan developed a number of powerful lines of thought, three of which are introduced here: the search for a theory of architecture; the establishment of a three-dimensional system of proportions named Plastic Number; and analogy as the mainspring of human thinking.This triad of deeply interconnected intellectual strategies represents his most important ‘instruments of thought’ and is rooted in the careful observation of phenomena as they are presented to us rather than relying on conventional beliefs.Van der Laan's instruments of thought lead us to reconsider the origins of human creation, urging a deeper examination of our perceptual and cognitive response to the limitlessness of the surrounding environment.On this basis, Van der Laan develops a unique philosophy of culture and design that includes considerations on the relationship between nature, culture, and religious ritual. Although this book is informative, its principal aim is to be formative.On the basis of Van der Laan’s instruments of thought, the authors develop a methodology to explore the Plastic Number theory and the many ways in which we perceive and interpret proportion.Reintroducing playful creativity and intellectual exploration into architectural pedagogy and design practice, this book is a gateway for a deeper understanding of the effects of the built environment on human behavior and the various ways in which the human mind perceives and decodes artifacts.

How do you calculate a proportion?
To calculate a proportion, you need to first determine the total number of items or individuals in the group you are interested in. Then, identify the specific subset of items or individuals that you are focusing on. Finally, divide the number of items in the subset by the total number of items in the group and multiply the result by 100 to get the proportion as a percentage. This will give you a numerical representation of the relationship between the subset and the total group.

What is an inverse proportion function?
An inverse proportion function is a mathematical relationship between two variables where one variable increases as the other variable decreases, and vice versa. In an inverse proportion function, as one variable doubles, the other variable is halved, and so on. This relationship is typically represented by the equation y = k/x, where y is one variable, x is the other variable, and k is a constant.
-
Is my three-part proportion correct?
To determine if your three-part proportion is correct, you should first ensure that the corresponding terms are correctly aligned. Then, you can cross-multiply to check if the equation holds true. If the cross-products are equal, then your three-part proportion is correct. Additionally, you can also solve for the missing term to verify if it satisfies the proportion.

Can you solve the task using a compound proportion? I can only handle the simple proportion.
Yes, the task can be solved using a compound proportion. In a compound proportion, there are multiple ratios involved, making it suitable for situations where there are more than two quantities being compared. However, if you are more comfortable with simple proportions, you can still solve the task by breaking it down into smaller steps and using multiple simple proportions to find the solution.
