Robert Katz Publications. 141. https://digitalcommons.unl.edu/physicskatz/141 This Article is brought to you for free and open access by the Research Papers in Physics and Astronomy at DigitalCommons@University of Nebraska - Lincoln. It has been accepted for inclusion in Robert Katz Publications by an authorized administrator of DigitalCommons@University of Nebraska - Lincoln. 11 Rotational Motion (The Dynamics of a Rigid Body) 11-1 Motion about a Fixed Axis The motion of the flywheel of an engine and of a pulley on its axle are examples of an important type of motion of a rigid body, that of the motion of rotation about a fixed axis. Consider the motion of a uniform disk rotat ing about a fixed axis passing through its center of gravity C perpendicular to the face of the disk, as shown in Figure 11-1. The motion of this disk may be de scribed in terms of the motions of each of its individual particles, but a better way to describe the motion is in terms of the angle through which the disk rotates. -

[Tweed and Textiles from Early Times to the Present Day]
[Tweed and Textiles from Early Times to the Present Day] The crofting way of life as it was lived in the Calbost area occupied the time of the whole population; both male and female during the four seasons of the year in a fully diversified way of life. Their work alternated from agriculture, fishing, kelping, weaving and knitting, cattle and sheep etc. etc. Some of that work was seasonal and some work was carried on inside during the winter months when it was difficult to participate in outdoor work because of the weather and the long winter evenings. Distaff – ‘Cuigeal’ The manufacture of cloth on order to protect him from the elements was one of man’s most ancient occupations and spinning was carried out by the distaff and spindle from an early date, yet it is believed that the distaff is still in use in parts of the world today. The distaff was also used extensively in Lewis in times past. A distaff is simply a 3 ft x 1½ inch rounded piece of wood with about 8 inches of one end flattened in order to hold the wool on the outer end as the distaff protrudes out in front of the spinner as she held it under her arm with a tuft of wool at the end. The wool from the distaff was then linked to the spindle ‘Dealgan’ or ‘Fearsaid’ which is held in the opposite hand and given a sharp twist by the fingers at the top of the spindle, in order to put the twist in the yarn as the spindle rotates in a suspended position hanging from the head. -

Alienazione, Ansia, Claustrofobia: “Anima” Di Thom Yorke È Un Sogno
Hamilton Santià IMPERDIBILE 17 luglio 2019 Alienazione, ansia, claustrofobia: “Anima” di Thom Yorke è un sogno ad occhi aperti nel mondo di oggi Nel suo terzo disco solista, il cantante dei Radiohead riesce nalmente a costruire una distopia contemporanea che racconta, in musica e immagini, il nostro attuale senso di scontta FABRICE COFFRINI / AFP Negli ultimi anni la musica elettronica, anche quella più commerciale e capace di emergere rispetto ai più fertili circoli dell’underground, si è fatta portatrice e interprete di un “common feel” sulle cose del mondo. Senso di ansia e di alienazione, una depressione permanente dovuta alla perdita di orizzonti, fallimenti collettivi e individuali, disastri su larga scala, incapacità di distinguere il vero dal falso e il sonno dalla veglia, ma anche una volontà di esaminare il vuoto attorno al quale si prova non più tanto a danzare, ma a muoversi con ostinata e ritmica resistenza. Come se la musica elettronica fosse diventata a sua volta un lunghissimo saggio teorico di critica culturale sull’esistente. A leggere le dichiarazioni di Thom Yorke che hanno anticipato l’uscita di Anima (qui potete leggere una bellissima intervista rilasciata a Crack), il suo terzo disco solista lontano dalla casa madre Radiohead è intriso di questo “common feel”. Del resto, senza andare a guardare nella parte post Kid A, la band di Oxford ha sempre ragionato molto su questi concetti: dall’alienazione giovanile di Creep all’insoddisfazione apatica verso il nulla di Just e Fake Plastic Trees, passando per l’ossessione per l’eccellenza di Fitter Happier (in piena esplosione cyberpunk, una voce robotica su suoni raccolti qui e là e ltrati sinteticamente che elogiava l’etica della produttività) e ovviamente l’esplosione perturbante di Paranoid Android. -
Math Unplugged(Opens in a New Tab)
Family Math math, we’ve got this! Everyone can participate in these puzzles, compare notes, and share solutions. Enjoy! Math Unplugged Long before computers, tablets, and cell phones, people used calculators that needed no electricity or batteries. They also looked for patterns in their calculations to check their work or to be able to compute faster. Unplugged Calculators You may have seen or even used an abacus. A version of the abacus like the one shown here is a popular toy today for young mathematicians. Have you ever used Napier’s bones to help multiply multiple-digit numbers? Many tools have been created throughout history to assist with numerical calculations. Find out more on your own about these mechanical calculators: • Blaise Pascal’s 17th-century calculating machine, the Pascaline • Gottfried Leibniz’s 18th-century automatic calculator, the Stepped Reckoner • Thomas de Colar’s 19th-century Arithmometer, the first machine used commercially Has anyone you know ever used a slide rule? It may be either rectangular or circular in shape, and its scale is based on logarithms. The slide rule is used for multiplication, division, and other higher-level math calculations. At first glance, the rectangular version of the tool looks like several rulers put together. On closer inspection, you see that the center ruler moves back and forth and that the numbers get closer together on the rule as you go to the right. High school math classes in the first half of the 20th-century included use of the slide rule. Abacus The abacus is the oldest known calculator on record, with historical evidence showing its use for over two thousand years. -
Michael Mission 105250 BAP210.1 Comparative Analysis of Two Producers Table of Contents
Comparative Analysis: Nigel Godrich and Timbaland Michael Mission 105250 BAP210.1 Comparative Analysis of Two Producers Table of Contents INTRODUCTION! 1 NIGEL GODRICH! 1 TIMBALAND! 1 PRODUCTION TRAITS! 2 CREATIVE ACCIDENTS! 2 THE BEAT MAKER! 3 IN COMPARISON! 4 CONCLUSION! 6 BIBLIOGRAPHY! 7 Nigel Godrich and Timbaland INTRODUCTION The ambiguous role of a music producer continues to escape common definition, made the more difficult in today’s ever growing expanse of musical genres and styles. McKinnon (2006), writing for CBC (Canadian Broadcasting Corporation) gives us a broad working definition: “Music producers are like film directors. They supervise the recording process, and are responsible for its final result.” Over recent decades, two significant individuals have had a major impact in shaping this very role; English producer Nigel Godrich and American producer Timothy Zachary Mosley better known to the world as ‘Timbaland’. The following essay analyses and compares these two individuals with particular focus on their key stylistic traits, their approach and methodologies and the techniques they employ in the craft of music production. NIGEL GODRICH Born in February 28, 1971, Godrich is best known for his close collaboration with the English five piece rock band Radiohead. The noted partnership began with a chance opportunity to record some B-sides during the band’s studio sessions for The Bends, “a notoriously difficult album for the band to make” (Robinson, 1997). His immediate connection with the band and his thorough knowledge of tape machines, mixing consoles and outboard gear made him the first port of call during the pre-production stages for Ok Computer (1997), Radiohead’s third studio album. -
