17 Things To Do in Saratov, Russia. 4 more images I do not know very much at this cathedral. I saw it from my Slovakia Hotel room and noticed that it fronted a square. From my research on the internet it appears that this church, and my hotel, are located in the city's oldest surviving neighborhood near Museum Square. In the past this square was formerly called Sobornaya Ploshchad or Cathedral Square. The eye-catching St. Here is the history of this cathedral as I researched it on the internet: The St. It is said that the fact that the cathedral has remained standing to this day is a miracle. I went into this cathedral and it is very elegantly appointed. I would recommend that you take a few minutes and see this remarkable cathedral in Saratov. 223 Physics Lab: The RC Circuit. 223 & 224 Lab Overview | Return to Physics 223 Labs Purpose This laboratory experiment is designed to investigate the behavior of capacitor responses of RC circuits, the basis for most electronic timing circuits.
An oscilloscope and digital multimeter will be used in this lab. Background (Footnotes in the text are provided with links to the footnotes section.) A capacitor is a common electronic circuit component that consists of two parallel plates separated by an insulating material called a dielectric. When a battery with voltage is connected across the capacitor, equal and opposite charges rapidly collect onto the plates due to the electric field created by the wires connecting the two plates1. While the other plate will have a net negative charge. . , is directly proportional to the applied potential difference, , and the constant of proportionality is known as the capacitance2, . Where is in coulombs, is in volts, and is in farads (after 19th century British physicists Michael Faraday). . At. 3cZJi.png (PNG Image, 300 × 200 pixels) An incredible map of which countries e-mail each other, and why. A normalized map of e-mail density between countries, where closer proximity indicates more e-mail.
The colors correspond to Huntington's "civilizations. " (Bogdan State et al) The Internet was supposed to let us bridge continents and cultures like never before. But after analyzing more than 10 million e-mails from Yahoo! Mail, a team of computer researchers noticed an interesting phenomenon: E-mails tend to flow much more frequently between countries with certain economic and cultural similarities. Among the factors that matter are GDP, trade, language, non-Commonwealth colonial relations, and a couple of academic-sounding cultural metrics, like power-distance, individualism, masculinity and uncertainty.
The findings were released in a paper titled "The Mesh of Civilizations and International Email Flows," written by researchers at Stanford, Cornell, Yahoo! Some of those anomalies could be attributed to cultural differences. An Introduction to the Findhorn Foundation. AP Ch 22 - Magnetism from Electricity. AP Ch 23 - Electricity from Magnetism.

Spherical coordinates can take a little getting used to. It’s probably easiest to start things off with a sketch. Spherical coordinates consist of the following three quantities.
First there is . Next there is . Finally there is . In summary, is the distance from the origin to the point, is the angle that we need to rotate down from the positive z-axis to get to the point and is how much we need to rotate around the z-axis to get to the point. We should first derive some conversion formulas. And want to find . Is the same in both coordinate systems. We will be able to do all of our work by looking at the right triangle shown above in our sketch. Is and so we can see that, and these are exactly the formulas that we were looking for. Note as well that, Or, Next, let’s find the Cartesian coordinates of the same point. Now all that we need to do is use the formulas from above for r and z to get, Also note that since we know that we get, Capacitors and RC Circuits. When capacitors are arranged in parallel, the equivalent capacitance is Ceq = C1 + C2 + C3 + ... When capacitors are arranged in series, the equivalent capacitance is 1 1 1 1 --- = --- + --- + --- + ...
Ceq C1 C2 C3 Combining capacitors and resistors together in a circuit produces a time-varying current. The timescale over which the current (or charge on the capacitor, or voltage across the capacitor) changes is time constant = R * C (seconds) Quantities in an RC circuit change exponentially, which means quickly at first, then more and more slowly. Values change by the same multiplicative factor (such as 1/2) in every equal step of time.
As one charges a capacitor in an RC circuit, -t/RC charge on capacitor = Co * ( 1 - e ) -t/RC current in circuit = Io * e As one discharges a capacitor in an RC circuit, -t/RC charge on capacitor = Co * e -t/RC current in circuit = Io * e Viewgraph 1 Viewgraph 2 Viewgraph 3 Viewgraph 4 Viewgraph 5 Viewgraph 6 Viewgraph 7 Viewgraph 8 Viewgraph 9.

China's Great Firewall: Activists Find New Ways Around It. When the censors push, people push back. That’s the message sent this week by activists and academics working to find new ways around China’s Great Firewall.
Last Friday, as part of an ongoing crackdown, China blocked the Chinese-language websites of Reuters and the Wall Street Journal. By Sunday, GreatFire.org, an anti-censorship group, effectively “unblocked” the site by building a copy, called a mirror site, that is hosted by Amazon Web Services. To shut down mirror sites like this, GreatFire says, China would have to block their cloud storage — calling attention to censorship and potentially jeopardizing Chinese businesses with Amazon-hosted sites.
On Wednesday, they used the same technique to create a mirror for China Digital Times, a media organization that calls attention to Chinese state censorship and is blocked on the Chinese mainland. Their work comes on the heels of two high-profile cases that have raised questions about the future of foreign reporting on China. Cosmographie-univers-visible-voie-lactegurumeditation_thumb.

Questions: 2, 4, 11, 14, 17 Problems: 5, 12, 13, 27, 29, 30, 38, 47, 92 Q2. The plates of a capacitor are connected to a battery. What happens to the charge on the plates if the connecting wires are removed from the battery? What happens to the charge if the wires are removed from the battery and connected to each other?
If the wires to the battery are disconnected, the charge remains on the plates -- and the voltage across the plates remains the same. Q4. Each pair will carry the same voltage. Q11. V)2 means that if V is doubled then ( V)2 will be increased by a factor of four so the potential energy is increased by four. Q14. The charge will remain the same. X or x so if the electric field is reduced the voltage, too, will be reduced. The corollary to this is, if the voltage is kept constant -- by connecting it to a battery -- then the charge stored on the capacitor will be increased.

How energy is really transferred in electric circuits - surface charges and the Poynting vector. In this section we try and answer the question: 'How does energy really flow in electric circuits? '. The answer is fairly standard university-level physics but is rarely mentioned in secondary school text books.
Richard Feynman described the theory as 'mad' (though he agreed it must be true). Energy is transferred through empty space outside the wires The essential point is that energy is transferred through empty space around (and NOT in) the wires of an electric circuit via an electromagnetic field called the Poynting field, named after the 19th century English physicist John Poynting. The direction of the Poynting field depends on electrons distributed over the surfaces of the wires in the circuit.
I have to admit it's quite a way outside my comfort zone but here is the gist. Distribution of charge for an isolated conductor Imagine you have an isolated length of wire. Electrons are different from atoms of gas in an empty container. Surface charges help the current turn corners. Interactive Graphic Organizer.

Japanese Rope ARt - Tutorials - Nawa Dojo. Kinbaku / Shibari Terms by Tatu. Return to Home | Tutorials Glossary Terms Related to Japanese Shibari / Kinbaku / Bondage Compiled by Tatu (c) 1999 / 2005 Please Note: I began compiling this glossary in August 1999 in an effort to first gain understanding of the Shibari / Kinbaku world for myself and also share what I have learned to the west. At the time as far as I know beyond a handful of terms defined in a few other websites, this was the first attempt to provide a major glossary of Japanese Shibari / Kinbaku terms in the west.
It has undergone several major revisions. As more and more have become interested in the Japanese Bondage world, and asking more and more questions, I began attempting to cite sources for these terms; and I continue to do so. I have learned along the way that what I thought were reliable sources turned out not to be so reliable. My thanks to those who have helped me in this endeavor and have helped me correct errors along the way.

(PhysOrg.com) -- Using the same quantum principles that enable the teleportation of information, a new proposal shows how it may be possible to teleport energy. By exploiting the quantum energy fluctuations in entangled particles, physicists may be able to inject energy in one particle, and extract it in another particle located light-years away. The proposal could lead to new developments in energy distribution, as well as a better understanding of the relationship between quantum information and quantum energy.
Japanese physicist Masahiro Hotta of Tohoku University has explained the energy teleportation scheme in a recent study posted at arxiv.org, called “Energy-Entanglement Relation for Quantum Energy Teleportation.” Previously, physicists have demonstrated how to teleport the quantum states of several different entities, including photons, atoms, and ions. In quantum energy teleportation, a physicist first makes a measurement on each of two entangled particles. Physics For Idiots - Electromagnetism. Charge comes in 2 types, positive and negative and is measured in Coulombs (C). If you have a charge on its own it emits a field in all directions. The field from a charge is represented by E as in E lectricity. If you put another charge in the field it experiences a force. Like charges repel and unlike charges attract. The bigger the charge the stronger the force and the further away the charges the weaker the force, exactly what you'd expect.
The q's are the two charges and r2 is the distance between them squared. Stuff Moving As soon as a charge starts to move it produces another field. Which is known as the Lorentz force. But we can already describe one of these bits, qE is just Coulombs Law so only half the work left to do. This is where its gets a little harder. Also, at A-level or below the situation will probably be simplified so you only have to consider the E and B fields separately. Circuits Which is Which?
