![]() ![]() It has a melting point of 28.5 ☌ (83.3 ☏), making it one of the few elemental metals that are liquid near room temperature. When in the presence of mineral oil (where it is best kept during transport), it loses its metallic lustre and takes on a duller, grey appearance. It is a very ductile, pale metal, which darkens in the presence of trace amounts of oxygen. ![]() Of all elements that are solid at room temperature, caesium is the softest: it has a hardness of 0.2 Mohs. Nonradioactive caesium compounds are only mildly toxic, but the pure metal's tendency to react explosively with water means that caesium is considered a hazardous material, and the radioisotopes present a significant health and environmental hazard.Ĭharacteristics Physical properties High-purity caesium-133 stored in argon. The radioactive isotope caesium-137 has a half-life of about 30 years and is used in medical applications, industrial gauges, and hydrology. Since the 1990s, the largest application of the element has been as caesium formate for drilling fluids, but it has a range of applications in the production of electricity, in electronics, and in chemistry. Since then, caesium has been widely used in highly accurate atomic clocks. In 1967, acting on Einstein's proof that the speed of light is the most-constant dimension in the universe, the International System of Units used two specific wave counts from an emission spectrum of caesium-133 to co-define the second and the metre. The first small-scale applications for caesium were as a " getter" in vacuum tubes and in photoelectric cells. The German chemist Robert Bunsen and physicist Gustav Kirchhoff discovered caesium in 1860 by the newly developed method of flame spectroscopy. It has the largest atomic radius of all elements whose radii have been measured or calculated, at about 260 picometers. Caesium-137, a fission product, is extracted from waste produced by nuclear reactors. It has only one stable isotope, caesium-133. It is the least electronegative element, with a value of 0.79 on the Pauling scale. It is pyrophoric and reacts with water even at −116 ☌ (−177 ☏). Caesium has physical and chemical properties similar to those of rubidium and potassium. It is a soft, silvery-golden alkali metal with a melting point of 28.5 ☌ (83.3 ☏), which makes it one of only five elemental metals that are liquid at or near room temperature. ![]() Caesium ( IUPAC spelling cesium in American English) is a chemical element with the symbol Cs and atomic number 55. ![]()

Description of Hay Day (from google play) ![]() ![]() ![]() This was developed into the Truman Doctrine. It must be the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures. In that speech he promised that the USA would provide aid to any country standing up to oppression: Truman had to persuade the usually isolationist US government to grant American money to support Greece’s fight against communism and laid out his reasons in a speech to Congress in March 1947. However, Britain was forced to withdraw its support due to lack of funds. Britain had been giving support to the anti-communist forces of the Greek government. From 1946 a civil war had been happening in Greece between its western-backed government and pro-communist forces. The Truman DoctrineĪmerican and British politicians were concerned about events in Greece and Turkey. In a nutshell, what Churchill meant by this was that the Allies had spent six years fighting for the freedom from fascism in Europe, only to have half the continent now under Soviet dictatorship. In that speech he famously noted that from Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the continent. On 5 March 1946, the by-now former British Prime Minister, Winston Churchill, condemned the Soviet expansion in Eastern Europe in his famous Iron Curtain speech. Why do you think American politicians rejected the idea of rollback? The Iron Curtain Speech Consider what groups would have preferred each of the two policies. ![]() A rollback approach would have involved American intervention to overturn a communist government in another country.Įxplain the difference between the policies of rollback and containment. The Americans rejected a policy of rollback, which would have been much more aggressive and confrontational. The USA would commit to a policy of containment, which meant stopping the spread of communism into Western Europe. The USSR would attempt to dominate Eastern Europe and spread communism where possible. ![]() These two telegrams set the scene for the Cold War in Europe. As a result, the USSR needed to secure its buffer zone in Eastern Europe. The Soviet response to The Long Telegram was The Novikov Telegram, in which the Soviet ambassador to the USA, Nikolai Novikov, warned that the USA had emerged from World War Two economically strong and bent on world domination. However, the USA was stronger than the USSR and so communism could be ‘contained’. It was determined to spread communism and therefore there could be no peaceful co-existence between the USSR and the USA. In much fewer than 8,000 words, what Kennan’s telegram said was that the USSR was heavily armed and feared the outside world. The American State Department had to be alerted by a Moscow-based official of the Soviets’ activities. Kennan’s response became known as The Long Telegram because at 8,000 words, it was indeed long! The importance of the Kennan telegram is that it shows that at this point there was still no concept of a Cold War. In 1946, George Kennan, an official at the US Embassy in Moscow, was asked to provide a summary of what the Soviets were up to and their intentions in Eastern Europe. An exchange of Telegrams The Long Telegram ![]() Now it seemed that in many countries the hard-won freedom from Nazi dictatorship was being replaced by communist dictatorships. World War Two had been fought in the name of freedom.

Upload the sketch to the Arduino Uno boardĬlick the Upload icon to upload the code to the control board. In this experiment, we use the active buzzer. ![]() The active buzzer is often more expensive than the passive one because of multiple built-in oscillating circuits. I tried doing this both in the code and trying to route the potentiometer through the GND line for the piezo. But a passive buzzer does not have such source, so it will not tweet if DC signals are used instead, you need to use square waves whose frequency is between 2K and 5K to drive it. So my problem is that for a project I am working on I want to be able to control the 'loudness' of my Piezo Buzzer with a potentiometer. The difference between an active buzzer and a passive buzzer is:Īn active buzzer has a built-in oscillating source, so it will make sounds when electrified. Turn the pins of two buzzers face up, and the one with a green circuit board is a passive buzzer, while the other enclosed with a black tape is an active one. Buzzers can be categorized as active and passive ones (see the following picture). Components Required:Īs a type of electronic buzzer with integrated structure, buzzers, which are supplied by DC power, are widely used in computers, printers, photocopiers, alarms, electronic toys, automotive electronic devices, telephones, timers and other electronic products for voice devices.

If you want to learn more about computer generating music, I would recommend Making Music with Computers: Creative Programming with Python: You can find the complete Arduino project on the article GitHub repository.ĭisclaimer, I don’t have formal musical training, if the reader sees or hears any discrepancies between the buzzer performance and the original Beethoven, please send corrections to the article GitHub repository. In a typical musical piece there are usually many parts that are repeated after a while, these parts can be stored in multiple arrays, e.g: 1 int play1 = This could be important for the Uno that has only 2048 bytes available for SRAM.įor this article, I’ve partially translated Für Elise by Ludwig van Beethoven to pitches and durations. A typical musical piece will use only a part of the available notes, so it will be a waste of memory to define the notes as a C array. The advantage of using the above macro definitions is low memory footprint and more memory available for the actual song. We can use a helper file that defines musical notes as C macro constants, e.g.: 1 //. If you want to play simple songs on the Arduino, you will need to translate a music sheet to a list of frequencies and durations. tone() can generate a square wave of a specified frequency (31 - 65535 Hz for Arduino Uno) and an optional duration in milliseconds: 1 tone ( pin, frequency, duration )įor example, the next instruction will generate a wave with a frequency of 200 Hz and a duration of 250 ms on pin 8: 1 tone ( 8, 200, 250 ) In order to play a note we will use the tone() function. In the next diagram, made with Fritzing, you can see a more clear picture of how the circuit was wired: Using the suggested potentiometer, wired in series with the buzzer, you can adjust the volume by increasing the resistance of the circuit. ![]() You can hook up the buzzer directly to an Arduino digital pin, but I find it to be annoyingly loud for high pitches. Last two components from the above list are optional, but recommended. These are the components that you will need to repeat the above experiment: ![]() ![]() ![]() Without R Markdown, the user would need to compute the mean and median, and then report it manually. We may want to explain in words, that the mean of the length of the petal is a certain value, while the median is another value. For instance, suppose we work on the iris dataset (preloaded in R). It is often the case that, when writing interpretations or detailing an analysis, we would like to refer to a result directly in our text. Ordered list, item 2īefore going further, I would like to introduce an important feature of R Markdown. ![]() Unordered list, item 2: * Unordered list, item 2.Unordered list, item 1: * Unordered list, item 1.Rmd file which contains blocks of R code (called chunks) and text is provided to the $$ The kableExtra package () is designed to extend the basic functionality of tables produced using knitr::kable() (see Section 10.1).Since knitr::kable() is simple by design (please feel free to read this as Yihui is lazy), it definitely has a lot of missing features that are commonly seen in other packages, and kableExtra has filled the gap perfectly. The production of the reports is done in two stages: Here is a table of sorts in some R printout. By dynamic, we mean that if your data changes, your results and your interpretations will change accordingly, without any work from your side. If you do not want to center a table, use the argument centering FALSE. Rmd file (and the data if external data are used of course), making it perfectly suited to collaboration and dissemination of results. Tables are center-aligned by default when they are included in a table environment (i.e., when the table has a caption). This enables readers to understand your results thanks to your interpretations and your comments, delivered as if you wrote a document explaining your work.Īnother advantage of R Markdown is that the reports are dynamic and reproducible by anyone who has access to the. For instance, after computing the main descriptive statistics and plotting some graphs, you can interpret them in the context of your problem and highlight important findings. By default pander will produce simple tables, but you. Text, comments and interpretations of the results. It is relatively powerful in that it will take summary() and anova() output and produce tables for them.This allows readers to see the results of your analyses. For example, the output of your linear model, plots, or results of the hypothesis test you just coded. This important table is discussed in nearly every textbook on regression. Results of the code, that is, the output of your analyses. The anova function can also construct the ANOVA table of a linear regression model, which includes the F statistic needed to gauge the model’s statistical significance (see Recipe 11.1, Getting Regression Statistics).This allows readers to follow your code and to check that the analyses were correctly performed. For instance, the data and the functions you used. ![]() R code to show how the analyses have been done.The first main advantage of using R Markdown over R is that, in a R Markdown document, you can combine three important parts of any statistical analysis: Rmd, while a R script file has the extension. Even if you never expect to present the results to someone else, it can also be used as a personal notebook to look back so you can see what you did at that time. The generated documents can serve as a neat record of your analysis that can be shared and published in a detailed and complete report. One using the longtable package (additional argument: longtable = TRUE) and the other using the booktabs package ( booktabs = TRUE).R Markdown allows to generate a report (most of the time in PDF, HTML, Word or as a beamer presentation) that is automatically generated from a file written within RStudio. But the documentation shows two examples for other formats. ![]() If you wish to show off your code you need to set echo TRUE in the chunk options. By default the R code will not be displayed in the final documents. Any output from R is included as you usually would using R Markdown. With format = Latex you get a horizontal line after each row. Using papaja, it is possible to run all your analyses from within an R Markdown document. It seems that you cannot freely adjust the lines of the table as you can do it with xtable (does anybody know more about this?). I used this Align two ames next to each other with knitr? which shows how to do it in html and this to align 2 Latex tables next to each other. ![]() |
