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 / 2

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.
How Can Apple Remain on Top?
Is Apple’s latest batch of new products enough to keep the company moving forward, or is it finally losing momentum after years of ruling the gadget world?
How to Read Aloud to Children-Julia Fowlkes Reads The Stray Dog
This video is a useful resource for teachers to learn effective strategies for using read alouds in the elementary classroom. The narrator is Julie Fowlkes, the lead trainer from BMABF. Her voice is animated and gives background knowledge before reading. College professors could use this in literacy instruction. (6:49)
Environmental responsibility
Complex questions of environmental responsibility are increasingly raised in times of change and uncertainty. The tracks on this album illustrate the need for nurturing a fresh sense of care for our environment as well as more appropriate forms of accountability. We demonstrate the necessity of addressing issues of entitlements, rights, obligations and duties if we are to critically and carefully shape our values in doing environmental responsibility and being environmentally responsible. This m

Talks At Google: Adrienne Mayor, "The Amazons"
Prof. Adrienne Mayor of Stanford visited Google's Cambridge, MA office to discuss her book, "The Amazons: Lives and Legends of Warrior Women across the Ancient World". It is the first comprehensive account of warrior women in myth and history across the ancient world, from the Mediterranean Sea to the Great Wall of China.
Adrienne Mayor is an independent folklorist/historian of science who investigates natural knowledge contained in pre-scientific myths and oral traditions. Her research looks

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

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 Conclusion This free course provided an introduction to studying Mathematics. It took you through a series of exercises designed to develop your approach to study and learning at a distance and helped to improve your confidence as an independent learner. 3.1 Alternative content Assistive technology can give access only to whatever is on the screen as part of the eLearning material; it doesn’t provide any alternative content, unless this is specifically added. For example, a screen reader cannot interpret visual content but it can read a description if one has been provided. Multimedia content might need to be supplemented with the same content in other formats. Deaf students need transcripts of audiovisual content.

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
Great whites have two lateral lines running from their complex ears all the way down both sides of their body. Because of them, they can sense the slightest vibrations of a seal from hundreds of feet away. (04:33)
