    the lens the less light get inside. The size of the opening is measured in “F-Stop” number. . This number normally falls between 1.4 and 32 but can go slightly beyond that range. Standard f-stop numbers would be as follows: 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22 and 32.The large apertures (where lots of light gets in) are given f/stop smaller numbers and smaller apertures (where less light gets in) have larger f-stop numbers. The images below show the effect of aperture on the exposure of the

    the image is in focus from the front of the photograph to the back of the photograph. Emphasis can be placed on a certain subject by obscuring the foreground or background. There are three main features that can affect depth of field. Lens aperture (f-stop), distance from the camera to the subject, and the focal length of the lens (Heart 100). In order to understand depth of field one must first understand how light works. We can view objects because of light rays reflecting off their surfaces

  • Field Photos

    In this task we had to show our ability to control ‘Depth of Field’ with aperture controls. We first had to look for photos that catch our attention and plan out how we will take our own photos inspired by the photos we found through google and Pinterest. After we planned that out and had a good idea of what we would take a photo of, how we were going to take it, where we would take it and when. Then we were ready to take out some cameras and get started. For my long depth of field photos, I wanted

    The Pinhole Camera History: By the fifth century, the beginnings of modern photography were underway. The first accounts of pinhole experimentation were recorded in the tenth century, when recorded Yu Chao-Lung used model pagodas to make pinhole images on a screen. Also, Arabian physicist and mathematician Alhazen (Ibn Al-Haitam) used pinholes to view an eclipse of the sun. He arranged three candles in a row and put a screen with a small hole between the candles and the wall, noting that

  • Telescopes

    Telescopes are an arrangement of lenses or mirrors or both that gathers visible light, permitted direct observation or photographic recording of distant objects. A telescope can be used in many ways such as viewing stars, moons, planets, looking at the city from a tall building, or looking at wildlife. All telescopes are not the same, some are better than others. There are three different kind of telescopes. Reflecting which uses two mirrors instead of lenses, Catadioptric (CAT) which combines lens

    The “earth” without art is just “eh.” Mother Nature is the greatest artist with the world as her canvas. The elements that surround us whether it’s terrain, lighting, wildlife or unpredictable weather; the world provides us with extraordinary color, texture, composition and inevitable beauty to capture and appreciate. Yet, how many times have you stood amidst an undeniably picturesque setting that seemed easy to capture yet when you look back at your photos they look so flat? (You can’t see me right

    Symphony Number 45 in F# Minor (the "Farewell symphony") Between 1761 and 1790 Haydn was employed by the enormously wealthy Esterhazy family who had two palaces on the borders of Austria and Hungary. The court orchestra was similar to that of many baroque orchestras - two oboes, a bassoon, a string ensemble and a harpsichord. But it also included a pair of horns - instruments that became a regular part of the orchestra thereafter. --------------------------------------------------------------------

    to the core’s octagonal face, allowing adjacent pieces to interlink and interlock. Since each octagon extension can rotate, the edges of the cube can rotate from the original position. (Any manipulation of that modifies the relative locations of a number of pieces is called a turn. At a basic level, each turn can be thought of as a rotation of one of the faces by some fitting degree.) When one of the core’s octagon extensions turns, it rotates the nine connected cubies with it. As rotation occurs

    in our heads that we don’t consciously recognize the procedures that we are using to solve the problem. For us, subtraction seems like something that has been ingrained in our thinking since the first day of elementary school. Not surprisingly, numbers and subtraction and “carry over” were new to us at some point, just like everything else that we know today. For Gretchen, a first-grader trying to solve 70-23, subtraction doesn’t seem like a piece of cake as she verbalizes her confusion, getting

Give an example of how/when you use fractions (including addition, subtraction, multiplication, division, and or ordering of) in your day to day activities outside of math class. Multiplying proper fractions requires a few steps. The first step will be to multiply the top two numbers also known as the numerators. Second you will multiply the bottom two numbers of the fraction; these are

No one has ever touched a number, nor would it be possible to do so. You may sketch a symbol on a paper that represents a number, but that symbol is not the number itself. A number is just understood. Nevertheless, numbers hold symbolic meaning. Have you ever asked yourself serious questions about the significance, implications, and roles of numbers? For example

In the past, mathematics was regarded as the science of quantity, whether of magnitudes, as in geometry, or of numbers, as in arithmetic, or of the generalization of these two fields, as in algebra. Toward the middle of the 19th century, however, mathematics came to be regarded increasingly as the science of relations, or as the science that draws necessary conclusions

    values are greater than other infinities. He also proved there are an infinite number of infinities. While all these ideas take a while to explain, I will go over how Cantor proved that the infinity for real numbers is greater than the infinity for natural numbers. The first important concept to learn, however, is one-to-one correspondence. Since it is impossible to count all the values in an infinite set, Cantor matched numbers in one set to a value in another set. The one set with values still left

  • Finding the Hidden Faces of a Cube

    Finding the Hidden Faces of a Cube In order to find the number of hidden faces when eight cubes are placed on a table, in a row, I counted the total amount of faces (6%8), which added up to 48. I then counted the amount of visible faces (26) and subtracted it off the total amount of faces (48-26). This added up to 22 hidden sides. I then had to investigate the number of hidden faces for other rows of cubes. I started by drawing out the outcomes for the first nine rows of cubes (below):

Various ways can be used to sharpen these skills including counting in steps of different sizes, practising mental calculations and the rapid recall of number facts; this can be done through playing interactive number games ‘a number one less than a multiple of 5’ etc. Mental calculations are introduced to children in the autumn term of year 1 at a basic level of addition and subtraction. In key stage 2 these mental calculations have

    addressing. Note that this only describes IPv4 subnets. Reading binary values Normally, you read binary numbers bytewise (8 bit wise). Start at the last bit, bit 0. If it is 1, add 2^0 to your number, else add 0. Then the next bit, bit 1, If it is 1, add 2^1 (2) to your number, If bit 3 is 1 add 2^2 (4) to your number, if bit 4 is 1 add 2^3 (8) to your number ... if bit 8 is 1 add 2^7 (128) to your number. You see, the base is always 2 because it can be either 0 or 1. Example 1: 10100100 = 2^7+0+2^5+0+0+0+2^2+0+0
