Alchemical Culture and Poetry in Early Modern England
Alchemical culture and poetry in early modern England PHILIP BALL Nature, 4–6 Crinan Street, London N1 9XW, UK There is a longstanding tradition of using alchemical imagery in poetry. It first flourished at the end of the sixteenth century, when the status of alchemy itself was revitalised in European society. Here I explain the reasons for this resurgence of the Hermetic arts, and explore how it was manifested in English culture and in particular in the literary and poetic works of the time. In 1652 the English scholar Elias Ashmole published a collection of alchemical texts called Theatrum Chymicum Britannicum, comprising ‘Several Poeticall Pieces of Our Most Famous English Philosophers’. Among the ‘chemical philosophers’ represented in the volume were the fifteenth-century alchemists Sir George Ripley and Thomas Norton – savants who, Ashmole complained, were renowned on the European continent but unduly neglected in their native country. Ashmole trained in law, but through his (second) marriage to a rich widow twenty years his senior he acquired the private means to indulge at his leisure a scholarly passion for alchemy and astrology. A Royalist by inclination, he had been forced to leave his London home during the English Civil War and had taken refuge in Oxford, the stronghold of Charles I’s forces. In 1677 he donated his impressive collection of antiquities to the University of Oxford, and the building constructed to house them became the Ashmolean, the first public museum in England. Ashmole returned to London after the civil war and began to compile the Theatrum, which was intended initially as a two-volume work. -
A Framework for the Static and Dynamic Analysis of Interaction Graphs
A Framework for the Static and Dynamic Analysis of Interaction Graphs DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Sitaram Asur, B.E., M.Sc. * * * * * The Ohio State University 2009 Dissertation Committee: Approved by Prof. Srinivasan Parthasarathy, Adviser Prof. Gagan Agrawal Adviser Prof. P. Sadayappan Graduate Program in Computer Science and Engineering c Copyright by Sitaram Asur 2009 ABSTRACT Data originating from many different real-world domains can be represented mean- ingfully as interaction networks. Examples abound, ranging from gene expression networks to social networks, and from the World Wide Web to protein-protein inter- action networks. The study of these complex networks can result in the discovery of meaningful patterns and can potentially afford insight into the structure, properties and behavior of these networks. Hence, there is a need to design suitable algorithms to extract or infer meaningful information from these networks. However, the challenges involved are daunting. First, most of these real-world networks have specific topological constraints that make the task of extracting useful patterns using traditional data mining techniques difficult. Additionally, these networks can be noisy (containing unreliable interac- tions), which makes the process of knowledge discovery difficult. Second, these net- works are usually dynamic in nature. Identifying the portions of the network that are changing, characterizing and modeling the evolution, and inferring or predict- ing future trends are critical challenges that need to be addressed in the context of understanding the evolutionary behavior of such networks. To address these challenges, we propose a framework of algorithms designed to detect, analyze and reason about the structure, behavior and evolution of real-world interaction networks. -
Experiment 12
Experiment 12 Velocity and Propagation of Waves 12.1 Objective To use the phenomenon of resonance to determine the velocity of the propagation of waves in taut strings and wires. 12.2 Discussion Any medium under tension or stress has the following property: disturbances, motions of the matter of which the medium consists, are propagated through the medium. When the disturbances are periodic, they are called waves, and when the disturbances are simple harmonic, the waves are sinusoidal and are characterized by a common wavelength and frequency. The velocity of propagation of a disturbance, whether or not it is periodic, depends generally upon the tension or stress in the medium and on the density of the medium. The greater the stress: the greater the velocity; and the greater the density: the smaller the velocity. In the case of a taut string or wire, the velocity v depends upon the tension T in the string or wire and the mass per unit length µ of the string or wire. Theory predicts that the relation should be T v2 = (12.1) µ Most disturbances travel so rapidly that a direct determination of their velocity is not possible. However, when the disturbance is simple harmonic, the sinusoidal character of the waves provides a simple method by which the velocity of the waves can be indirectly determined. This determination involves the frequency f and wavelength λ of the wave. Here f is the frequency of the simple harmonic motion of the medium and λ is from any point of the wave to the next point of the same phase. -
Tuning a Guitar to the Harmonic Series for Primer Music 150X Winter, 2012
Tuning a guitar to the harmonic series For Primer Music 150x Winter, 2012 UCSC, Polansky Tuning is in the D harmonic series. There are several options. This one is a suggested simple method that should be simple to do and go very quickly. VI Tune the VI (E) low string down to D (matching, say, a piano) D = +0¢ from 12TET fundamental V Tune the V (A) string normally, but preferably tune it to the 3rd harmonic on the low D string (node on the 7th fret) A = +2¢ from 12TET 3rd harmonic IV Tune the IV (D) string a ¼-tone high (1/2 a semitone). This will enable you to finger the 11th harmonic on the 5th fret of the IV string (once you’ve tuned). In other words, you’re simply raising the string a ¼-tone, but using a fretted note on that string to get the Ab (11th harmonic). There are two ways to do this: 1) find the 11th harmonic on the low D string (very close to the bridge: good luck!) 2) tune the IV string as a D halfway between the D and the Eb played on the A string. This is an approximation, but a pretty good and fast way to do it. Ab = -49¢ from 12TET 11th harmonic III Tune the III (G) string to a slightly flat F# by tuning it to the 5th harmonic of the VI string, which is now a D. The node for the 5th harmonic is available at four places on the string, but the easiest one to get is probably at the 9th fret. -

Homelab 2 [Solutions]
Homelab 2 [Solutions] In this homelab we will build a monochord and measure the fundamental and harmonic frequencies of a steel string. The materials you will need will be handed out in class. They are: a piece of wood with two holes in it, two bent nails, and a steel guitar string. The string we will give you has a diameter of 0.010 inch. You will also find it helpful to have some kind of adhesive tape handy when you put the string on the monochord. As soon as you can, you should put a piece of tape on the end of the string. The end is sharp and the tape will keep you from hurting your fingers. Step 1 Push the nails into the holes as shown above. They should go almost, but not quite, all the way through the board. If you push them too far in they will stick out the bottom, the board will not rest flat, and you might scratch yourself on them. You won't need a hammer to put the nails in because the holes are already big enough. You might need to use a book or some other solid object to push them in, or it might help to twist them while you push. The nails we are using are called 'coated sinkers.' They have a sticky coating that will keep them from turning in the holes when you don't want them to. It cannot be iterated enough to be careful with the nails. Refer to the diagram above if you are unsure about how the final product of this step looks like. -

Guitar Harmonics - Wikipedia, the Free Encyclopedia Guitar Harmonics from Wikipedia, the Free Encyclopedia
3/14/2016 Guitar harmonics - Wikipedia, the free encyclopedia Guitar harmonics From Wikipedia, the free encyclopedia A guitar harmonic is a musical note played by preventing or amplifying vibration of certain overtones of a guitar string. Music using harmonics can contain very high pitch notes difficult or impossible to reach by fretting. Guitar harmonics also produce a different sound quality than fretted notes, and are one of many techniques used to create musical variety. Contents Basic and harmonic oscillations of a 1 Technique string 2 Overtones 3 Nodes 4 Intervals 5 Advanced techniques 5.1 Pinch harmonics 5.2 Tapped harmonics 5.3 String harmonics driven by a magnetic field 6 See also 7 References Technique Harmonics are primarily generated manually, using a variety of techniques such as the pinch harmonic. Another method utilizes sound wave feedback from a guitar amplifier at high volume, which allows for indefinite vibration of certain string harmonics. Magnetic string drivers, such as the EBow, also use string harmonics to create sounds that are generally not playable via traditional picking or fretting techniques. Harmonics are most often played by lightly placing a finger on a string at a nodal point of one of the overtones at the moment when the string is driven. The finger immediately damps all overtones that do not have a node near the location touched. The lowest-pitch overtone dominates the resulting sound. https://en.wikipedia.org/wiki/Guitar_harmonics 1/6 3/14/2016 Guitar harmonics - Wikipedia, the free encyclopedia Overtones When a guitar string is plucked normally, the ear tends to hear the fundamental frequency most prominently, but the overall sound is also 0:00 MENU colored by the presence of various overtones (integer multiples of the Tuning a guitar using overtones fundamental frequency). -
Historical Influence of the Rosicrucian Fraternity on Freemasonry
Historical Influence of the Rosicrucian Fraternity on Freemasonry Introduction Freemasonry has a public image that sometimes includes notions that we practice some sort of occultism, alchemy, magic rituals, that sort of thing. As Masons we know that we do no such thing. Since 1717 we have been a modern, rational, scientifically minded craft, practicing moral and theological virtues. But there is a background of occult science in Freemasonry, and it is related to the secret fraternity of the Rosicrucians. The Renaissance Heritage1 During the Italian renaissance of the 15th century, scholars rediscovered and translated classical texts of Plato, Pythagoras, and the Hermetic writings attributed to Hermes Trismegistus, thought to be from ancient Egypt. Over the next two centuries there was a widespread growth in Europe of various magical and spiritual practices – magic, alchemy, astrology -- based on those texts. The mysticism and magic of Jewish Cabbala was also studied from texts brought from Spain and the Muslim world. All of these magical practices had a religious aspect, in the quest for knowledge of the divine order of the universe, and Man’s place in it. The Hermetic vision of Man was of a divine soul, akin to the angels, within a material, animal body. By the 16th century every royal court in Europe had its own astrologer and some patronized alchemical studies. In England, Queen Elizabeth had Dr. John Dee (1527- 1608) as one of her advisors and her court astrologer. Dee was also an alchemist, a student of the Hermetic writings, and a skilled mathematician. He was the most prominent practitioner of Cabbala and alchemy in 16th century England. -

The Physics of a Longitudinally Vibrating “Singing” Metal Rod
UIUC Physics 193/406 Physics of Music/Musical Instruments The Physics of a Longitudinally Vibrating Metal Rod The Physics of a Longitudinally Vibrating “Singing” Metal Rod: A metal rod (e.g. aluminum rod) a few feet in length can be made to vibrate along its length – make it “sing” at a characteristic, resonance frequency by holding it precisely at its mid-point with thumb and index finger of one hand, and then pulling the rod along its length, toward one of its ends with the thumb and index finger of the other hand, which have been dusted with crushed violin rosin, so as to obtain a good grip on the rod as it is pulled. L L L L/2 L/2 Pull on rod here along its length Hold rod here with thumb with violin rosin powdered thumb and index finger of one hand and index finger of other hand, stretching the rod The pulling motion of the thumb and index finger actually stretches the rod slightly, giving it potential energy – analogous to the potential energy associated with stretching a spring along its length, or a rubber band. The metal rod is actually an elastic solid – elongating slightly when pulled! Pulling on the rod in this manner excites the rod, causing both of its ends to simultaneously vibrate longitudinally, back and forth along its length at a characteristic resonance frequency known as its fundamental frequency, f1. For an excited aluminum rod of length, L ~ 2 meters, it is thus possible that at one instant in time both ends of the rod will be extended a small distance, L ~ 1 mm beyond the normal, (i.e. -
