Doodling is a great stress-reliever and can help you through a creative block or a long meeting. Sometimes, you don’t want to create masterworks, or even finished drawings – you just want to let your pencil or pen go for a walk and see what happens. It’s barely there and easy to fade out when you publish your finished piece on Instagram. Unlike a lined pad, a dotted paper notebook’s ruling won’t cut through the downstrokes on under-hanging letters and create an unsightly interruption of your flowing script. Not only will a dotted ruling keep your lettering perfectly horizontal on the page, it also helps you to keep even spacing between letters and words, and to make sure your letter forms (‘e’s, ‘a’s, the tails of your ‘y’ and so on) are consistent and beautifully even. For practicing calligraphyĬaught the hand-lettering bug? If you’re into calligraphy, or if you fancy giving it a try, a dot grid journal is a great item to have in your kit. You’ll be able to use an eraser without buckling or wearing the paper, go over lines, and use ink without worrying that it will bleed through. If you’re using a dotted notebook as a sketchpad, it’s important to have good quality paper (our 100gsm Munken Kristall, for example) to work on. Say you’re drawing a group of people – if you can see that someone’s head is two dots high, you can use that two-dot measure for other people in the picture and keep everyone’s proportions the same. They can also lend a hand when it comes to perspective drawing and mapping out geometric forms like buildings and cityscapes.įinally, you can use them to help you gauge proportions between different elements of your drawing. They can help with composition, as you’ll be able to better portion out the page for different parts of your drawing. As a dot grid sketchbookĭots can add an extra element of structure to your sketch practice. Or you can box off different parts of the page so you can capture ideas in a non-linear way. With a dotted page, you have the added benefit of being able to break out of lined text into doodles or sketches when the mood takes you. It may take a little practice, but you’ll be into the swing of it after a line or two. Just use the horizontal dots the way you’d use lines in a ruled notebook. Record thoughts, impressions, memories and ideas – whatever helps you to de-stress or process your day. Now is the perfect time to start a daily diary. If so, we have you covered with a whole list of suggestions for how to use a dotted notebook. Or you may be in search of a little inspiration. If you’re lucky enough to be the owner of a MOO Notebook or Journal with dotted pages, you may already be bursting with ideas for how to use it. But they don’t make so much of an impact that they get in the way of drawings or make your page look cluttered.īest of all, they’re easy to fade out of your photographs using filters and editing tools, so you can post images online and give the impression that you started with a blank page. Regularly spaced dots can be used to keep handwriting on an even keel, add structure to a table or checkbox layout, or give you the backbone of a diagram. It feels like a blank sheet of paper… but with built-in autopilot. The dot grid however is the goldilocks option – a happy compromise between blank, ruled and squared pages. They just didn’t leave much room for artistic flourishes or creative expression. But they also made pages look a little denser. These made it easier to do things like draw diagrams or lay out a table of figures. Then there was the squared pages option, which often brought back memories (good or otherwise) of math homework. Ruled lines meanwhile help those whose handwriting tends to slant off into oblivion, as can sometimes happen on a blank page. Unruled Blank pages have long been the preference of creatives looking to sketch and doodle. Traditionally, notebook pages came in three options: unruled, wide ruled or narrow ruled. Thanks to its versatility and less-is-more appeal the dotted notebook page has been quite ‘the thing’ recently – just ask the journalers of Instagram. There’s nothing plain about the fresh trend in the notebook world – it’s dots! Here’s all you need to know to get the most out of your MOO Hardcover Journal – dot grid version. (He also had several mistresses, including Cleopatra VII, Queen of Egypt, with whom he had a son, Caesarion.) First TriumvirateĪt the same time Caesar was governing under Pompey, he aligned himself with the wealthy military leader Marcus Licinius Crassus. The same year, Caesar wed Calpurnia, a teenager to whom he remained married for the rest of his life. Caesar maintained his alliance with Pompey, which enabled him to get elected as consul, a powerful government position, in 59 BCE. In 61 to 60 BCE, Caesar served as governor of the Roman province of Spain. Their marriage lasted just a few years, and in 62 BCE, the couple divorced. In 67 BCE, Caesar married Pompeia, the granddaughter of Sulla. Caesar went on to serve in several other key government positions. Soon after, in 68 or 69 BCE, he was elected quaestor (a minor political office). The pirates were captured and executed.Ĭaesar further enhanced his stature in 74 BCE when he put together a private army and combated Mithradates VI Eupator, king of Pontus, who had declared war on Rome.Ĭaesar began an alliance with Gnaeus Pompey Magnus, a powerful military and political leader. In a daring display of his negotiation skills and counter-insurgency tactics, he convinced his captors to raise his ransom, then organized a naval force to attack them. He relocated temporarily to Rhodes to study philosophy.ĭuring his travels he was kidnapped by pirates. In 69 BCE, Cornelia passed away.Īfter Sulla’s death, Caesar began his career in politics as a prosecuting advocate. Caesar likely returned to Rome after Sulla’s death circa 79 BCE (another account states Caesar, with the help of his influential friends, eventually convinced Sulla to be allowed to return).īack in Rome, Caesar and Cornelia had a daughter, Julia Caesaris, in 76 BCE. The young Roman refused and escaped by serving in the military, first in the province of Asia and then in Cilicia. Sulla ordered Caesar to divorce his wife or risk losing his property. Caesar’s marriage to Cornelia drew the ire of the Roman dictator Sulla, as Cornelia’s father was Sulla’s political rival. In 84 BCE, Caesar married Cornelia, the daughter of a nobleman. Around the time of his father’s death, Caesar made a concerted effort to establish key alliances with the country’s nobility, with whom he was well-connected. He remained close to his mother, Aurelia. When he was 16, his father, an important regional governor in Asia also named Gaius Julius Caesar, died. Little is known of Caesar’s early years, but during his youth an element of instability dominated the Roman Republic, which had discredited its nobility and seemed unable to handle its considerable size and influence. SPOUSE: Cornelia (84–69 BCE), Pompeia (67–62 BCE), Calpurnia (59–44 BCE)īorn Gaius Julius Caesar on July 12, 100 BCE, Caesar hailed from Roman aristocrats, though his family was far from rich. After several alliances and military victories, he became dictator of the Roman Empire, a rule that lasted for just one year before his death in 44 BCE. By age 31, Caesar had fought in several wars and become involved in Roman politics. Allegedly a descendant of Trojan prince Aeneas, Caesar’s birth marked the beginning of a new chapter in Roman history. Julius Caesar was a leader of ancient Rome who significantly transformed what became known as the Roman Empire by greatly expanding its geographic reach and establishing its imperial system. Joule died in the same year, on 11 October 1889.Īt the fourth congress (1893), the "international ampere" and "international ohm" were defined, with slight changes in the specifications for their measurement, with the "international joule" being the unit derived from them. "Such a heat unit, if found acceptable, might with great propriety, I think, be called the Joule, after the man who has done so much to develop the dynamical theory of heat." Īt the second International Electrical Congress, on 31 August 1889, the joule was officially adopted alongside the watt and the quadrant (later renamed to henry). The naming of the unit in honour of James Prescott Joule (1818–1889), at the time retired but still living (aged 63), is due to Siemens: Wilhelm Siemens, in his inauguration speech as chairman of the British Association for the Advancement of Science (23 August 1882) first proposed the Joule as unit of heat, to be derived from the electromagnetic units Ampere and Ohm, in cgs units equivalent to 10 7 erg. The erg was adopted as its unit of energy in 1882. The cgs system had been declared official in 1881, at the first International Electrical Congress. As with every SI unit named for a person, its symbol starts with an upper case letter (J), but when written in full it follows the rules for capitalisation of a common noun i.e., " joule" becomes capitalised at the beginning of a sentence and in titles, but is otherwise in lower case. The joule is named after James Prescott Joule. This relationship can be used to define the watt. The work required to produce one watt of power for one second, or one watt-second (W⋅s) (compare kilowatt-hour, which is 3.6 megajoules).This relationship can be used to define the volt. The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one coulomb-volt (C⋅V).One joule can also be defined by any of the following: J = k g ⋅ m 2 ⋅ s − 2 = N ⋅ m = P a ⋅ m 3 = W ⋅ s = C ⋅ V (25.4 x 20.3 cm) See more items in National Museum of African American History and Culture Collection Classification Media Arts-Photography National Museum of African American History and Culture Topic African American Actors Film Record ID nmaahc_2013.49.13.

Then, at the opposite end are the Catholic nuns, who are already deterred. “First, the undeterrable, the psychopaths, where deterrence doesn’t work at all. “There are three general types,” he said. Most helpful to the judges in the audience was Finckenauer’s discussion of deterrence in the general population. “Kids don’t see beaten down losers.” It’s a disconnect. “Big, muscular, tough guys are what the kids see during a prison tour as the inmates yell and scream at them in the hopes of scaring them out of committing a crime,” Finckenauer said. That’s why the television series is popular with adults, but unsuccessful with kids. “Scared straight programs are developed by adults for kids, but kids don’t react the same way as adults,” Finckenauer said. What young people react to is: (1) How swift is the punishment in terms of the behavior? (2) How certain is it that a consequence will occur? and (3) How severe is the punishment? The extreme nature of the punishment shown in “scared straight” programs doesn’t match the expectations of young people. They believe they might not get caught when they think about committing a crime. “Kids know how hit and miss the criminal justice system is. They are impulsive, and think short term, especially when it comes to punishment.”įinckenauer mentioned a kind of “optimism” that works against vicarious deterrence. “Teenagers don’t think like that, they don’t think logically or long term. “Those programs require young people to project into the future,” Finckenauer said. First, “Scared straight” programs arise out of the concept of “vicarious deterrence,” which he defined as “avoiding behavior by experiencing what happens to others.” Will it change when they can’t fight back?” Why wouldn’t it work on at-risk teens? What was wrong with the headline: “They think they’re fighters. After all, I thought, I certainly would have been “scared straight” after experiencing a day in prison, including being yelled at by brutal inmates, clanging bars, menacing guards, etc. I confess, I was one of the judges who accepted the evidence that “scared straight,” programs didn’t work, but I couldn’t figure out why. Finckenauer, author of “Scared Straight! and the Panacea Phenomenon,” cogently explained why those programs don’t work by examining the concept of “deterrence” as applied to teenage thinking and behavior. The show is a spin off of the multiple award-winning documentary films also produced by Arnold Shapiro.īut do “scared straight” programs really work to reduce juvenile crime? “No,” claimed Professor James Finckenauer, Ph.D., from Rutgers University School of Criminal Justice, in his address to the National Conference of Juvenile and Family Court Judges in New York City in July. The hit series from Disney’s A&E Network became the most watched original series launch in the network’s history with an audience of 3.7 million people. The “Beyond Scared Straight” message: “In prison for a day to stay out for life” certainly appeals to a television audience. It works by controlling the “random” events that the world throws at you.

If the velocities are v1 and v2 at times t1 and t2 respectively, then When the acceleration is plotted as a function of time, it is acceleration – time graph (Fig. The area under the v – t curve, between the given intervals of time, gives the change in displacement or the distance travelled by the particle during the same interval. If the displacements are s1 and s2 in times t1 and t2, then When the velocity of the particle is plotted as a function of time, it is velocity-time graph.Īs a = dv/dt, the slope of the v – t curve at any instant gives the acceleration of the particle (Fig. below the particle at time t1, has a positive velocity, at time t2, has zero velocity and at time t3, has negative velocity. When the displacement of the particle is plotted as a function of time, it is displacement – time graph. As v = ds/dt, the slope of the s – t graph at any instant gives the velocity of the particle at that instant. acceleration – time graph (a – t graph).displacement – time graph (s – t graph).Line graphs are used to show the relation of one quantity say displacement or velocity with another quantity such as time. If the displacement, velocity and acceleration of a particle are plotted with respect to time, they are known as, The graphs provide a convenient method to present pictorially, the basic informations about a variety of events. The negative acceleration is called retardation or deceleration.Ī particle is in uniform motion when it moves with constant velocity (i.e) zero acceleration. If the velocity decreases with time, the acceleration is negative. If the velocity changes by an equal amount in equal intervals of time, however small these intervals of time may be, the acceleration is said to be uniform. Its unit is m s−2 and its dimensional formula is LT−2. The instantaneous acceleration is, a= dv/dt = d/dt =(ds/dt)=d2s/dt2 If u is the initial velocity and v, the final velocity of the particle after a time t, then the acceleration, Acceleration is a vector quantity.Īcceleration = change in velocity/time taken If the magnitude or the direction or both of the velocity changes with respect to time, the particle is said to be under acceleration. Acceleration of a particle is defined as the rate of change of velocity. It is the velocity at any given instant of time or at any given point of its path. Vaverage = change in displacement / change in timeįrom the graph, it is found that the slope of the curve varies. The average velocity during the time interval (t2 – t1) is defined as Let s1 be the displacement of a body in time t1 and s2 be its displacement in time t2 (Fig.below). The velocity is variable (non-uniform), if it covers unequal displacements in equal intervals of time or if the direction of motion changes or if both the rate of motion and the direction change. below) the slope is constant at all the points, when the particle moves with uniform velocity. Its unit is m s−1 and its dimensional formula is LT−1.Ī particle is said to move with uniform velocity if it moves along a fixed direction and covers equal displacements in equal intervals of time, however small these intervals of time may be. In a displacement – time graph, (Fig. It is also defined as the speed of the particle in a given direction. The velocity of a particle is defined as the rate of change of displacement of the particle. It is the distance travelled in unit time. The distance travelled is a scalar quantity and the displacement is a vector quantity. For example, if the particle moves from a point O to position P1 and then to position P2, its displacement at the position P2 is – x2 from the origin but, the distance travelled by the particle is x1+x1+x2 = (2×1+x2) (Fig below). The distance travelled by a particle, however, is different from its displacement from the origin. The motion of a particle can be described if its position is known continuously with respect to time. The total length of the path is the distance travelled by the particle and the shortest distance between the initial and final position of the particle is the displacement. Position, displacement and distance travelled by the particle The important parameters required to study the motion along a straight line are position, displacement, velocity, and acceleration. The motion along a straight line is known as rectilinear motion. |
