Exploring Complex Forms in Nature Through Mathematical Modeling: a Case on Turritella Terebra
Changing paradigm of nature-architecture relationship has being directly affected from developing science and technologies as well as from the impact of biomimetic inventions in various man made designs. Our perception of forms and structures are also shifting through use of computational techniques. From this aspect, mathematical models can be considered as the first step to analyze the complex forms and structures in nature. In this paper it is aimed to initiate a platform in architecture whic

2.5 Critical current

The current density for a steady current flowing along a wire in its normal state is essentially uniform over its cross-section. A consequence of this is that the magnetic field strength B within a wire of radius a, carrying current I, increases linearly with distance from the centre of the wire, and reaches a maximum value of μ0I / 2Author(s): The Open University

Notes on the Synthesis of Form
Every design problem begins with an effort to achieve fitness between two entities: the form in question and its context. The form is the solution to the problem; the context defines the problem. We want to put the context and the form into effortless contact or frictionless coexistence, i.e., we want to find a good fit. For a good fit to occur in practice, one vital condition must be satisfied. It must have time to happen. In slow-changing, traditional, unselfconscious cultures, a form is adjus

Introduction

We are used to seeing spectacular astronomical images in the press and on the internet. This course gives an in-depth introduction to two of the most important instruments used to create these images and explore the science behind them – telescopes and spectographs.

This course is drawn from the preparatory work for the practical residential school at the Observatori Astronomic de Mallorca. The course image shows a student at work in one of the telescope domes at the Observatori.

The Art of Teaching the Arts: Choosing Instructional Approaches
Arts teachers take on a variety of roles, and use many different instructional techniques, as they engage with their students. Teachers can be instructors, mentors, directors, coaches, artists, performers, collaborators, facilitators, critics, or audience members. In this session, participants follow a vocal music teacher as she takes on different roles in order to encourage students to find creative solutions to artistic challenges. Next, an acting teacher becomes a facilitator as his students

7.2 The eubacterial chromosome

Some of the diverse roles of chromatin components can be illustrated by examining the E. coli chromosome. Like most prokaryotes, E. coli has a single chromosome consisting of a single double-stranded circular DNA molecule. There is no nucleus present, but the E. coli DNA is within a discrete entity in the cytoplasm called the nucleoid. The nucleoid contains a multitude of proteins and is in close proximity to the ribosomes, where translation occurs. In addition to

3.5 Summary of Section 3

Behavioural mechanisms for reducing water loss are integrated with physiology. While Dipodomys rests in a cool burrow, the nasal counter-current heat exchanger cools exhaled air, conserving water vapour evaporated from respiratory surfaces. Long loops of Henle operate as counter-current multipliers, producing highly concentrated urine. Desert foxes use panting for evaporative cooling, but high rates of evaporative water loss cannot be sustained; hence the crucial importance of dens for

3.6 Summary of Section 3

Sound waves received by the ear are turned into neural activity by a complex mechanism involving the eardrum, the bones in the middle ear, and the hair cells within the cochlea. The auditory nerve carries the signal from the ears to the brainstem, from where it passes via the thalamus to the auditory areas of the cerebral cortex. In the cortex, speech sounds are extracted from the incoming signal. There are neural circuits in the auditory cortex that are specialised for speech and language as

2 Solar thermal energy

Solar heating of trapped air, water and solids has been used for centuries, but modern architectural design can enhance all three effects for space heating, hot water supply and heat storage. Such passive solar heating relies on short-wave radiation being absorbed by materials so that they heat up and then slowly re-emit long-wave radiation. The most obvious example is inside a greenhouse, where solar radiation that passes through the glass heats the inside air to temperatures well abo
