Be sure to write your name & answer all short answer questions in complete sentences. Measurements and Numbers in Astronomy Astronomy is a branch of science. You will be exposed some numbers expressed in SI units, large and small numbers, and some numerical operations such as addition / subtraction, multiplication / division, and ratio comparison. Lets watch part of a IMAX movie called Cosmic Voyage. http://www.youtube.com/watch?v=1BX-lfK5JLI or http://www.videosurf.com/video/cosmic-voyage-excerpt-61169985?t=18 Scientific notation or powers of 10 notation Astronomy is a subject of extremes (very large numbers and very small numbers) Examples include how many stars in the universe, how many galaxies, the distance to far away stars, length of time, density of giant molecular gas clouds, wavelength measurements, etc. For these very large and very small numbers, it is convenient to use “powers of 10” (or “scientific”) notation. Powers of ten notation expresses the number by using multiples of 10 with exponent numbers. Often a single digit is followed by the decimal point and any other digits, then the exponent. For large numbers: For small numbers: 1 no zero = 10 0 10 1 zero = 10 1 0.1 = 1/10 Divided by 10 =10 -1 100 2 zero = 10 2 0.01 = 1/100 Divided by 100 =10 -2 1000 3 zero = 10 3 0.001 = 1/1000 Divided by 1000 =10 -3 Exercise: Example: 200 = 2 x 100 = 2 x 10 2 1500 = 1.5 x 1000 = 1.5 x 10 3 40,000 = 9,000,000 = 12,700 = 380,000 = example: 0.017 = 1.7 x 10 -2 0.003 = 0.0000005 = 0.00205 = 3 Distance or length measurements In astronomy, we use meters (or variations of that: km, cm, mm, nm etc), astronomical units and light years. To measure the distance to objects that are nearby or to measure size of an object we generally use km. For distance within the solar system, we use astronomical units. For far away objects, light years are used. Complete the chart below: For some part, you must use a ruler to make measurements. Convert to: If the # is large or small, Object Unit be sure to use sci notation Your astronomy book cm m 2 meter stick m cm Pen cm m Your height cm m Wave length of green light 550nm m Radius of the Earth 6,400,000 m km The distance light travels in one 300,000km m second. 1km = 1000m, 1m = 100cm, 1m = 1,000,000,000nm 4 For the following calculations, please show your work and draw a box around your final answer. Please check if you have the correct unit for the final answer. Astronomical unit: average distance between _____________ and ______________. 1AU = 1.5x108km Mercury’s average distance form the sun is 57,900,000km. Show this # in AU: ___________________ Jupiter’s average distance from the sun is 5.2 AU. Show this # in km: ______________________ Light Year: distance that light travels in vacuum in one year: 1 ly = 9.5x1012km = 63,000 AU Nearest star, Proxima Centauri is 4.2 lys away. Show this # in km: The brightest star in the night sky, Sirius, is 8.6 ly away. Show this # in km: Temperature In astronomy we use the Kelvin as unit of temperature (1K is the same incremental value as 1°C). The Kelvin scale is named after British physicist Lord Kelvin. In the Kelvin scale, water boils at 373K and freezes at 273K. To convert: Fahrenheit and Kelvin: TK = (5/9)*(TF – 32) + 273 or TF = (9/5) * (TK -273)+32 o Example: let’s say it is 75 F in this room. TK = (5/9)*(75– 32) + 273 = 297K Water boiling temperature 373K oF Surface temperature of Titan K -290 oF (Saturn) Surface temperature of Mercury at K 750 oF hottest Surface temperature of the Sun 5800K oF Show sample calculation: 5 Angular Measurements: The Ancients invented angles and a system of angular measurement that can be used to pinpoint a direction as well as the apparent size of the object far away. o • Circle is broken up into 360 equal segments, called degrees (circle = 360 ) o • One degree is further divided into 60 segments, called arc minutes (1’ = 1/60 ) o • One arc minute is divided into 60 segments, called arc seconds (1” = 1/60‘ = 1/3600 ) Circle demo In astronomy we often measure the angular size of celestial object before we truly find out the actual size of the object. Following exercise is to help you gain better feel for angular measurements! At arm’s length, which circle do you think is closest to the diameter of the Sun? _________________ Go outside and stand on a blue “X.” Measure the angular sizes of various objects from where you stand, using your “hand tools.” Station Object Estimated angular size (o) Height from the ground to the top of the 1 Building 60 railing: Height from the ground to the top of 1 Building 7: Height from the ground to the top of the 2 Building 60 railing: Height from the ground to the top of 2 Building 7: Height from the ground to the top of the 3 Building 60 railing: Height from the ground to the top of 3 Building 7: Width of one pane of window on 1st floor of 3 building 7: Height of the number “60” of the northeast 3 corner: What do you conclude from comparing your observations from stations 1 and 2? 6 .

    Appendix B. Random Number Tables Reproduced from Million Random Digits, used with permission of the Rand Corporation, Copyright, 1955, The Free Press. The publication is available for free on the Internet at http://www.rand.org/publications/classics/randomdigits. All of the sampling plans presented in this handbook are based on the assumption that the packages constituting the sample are chosen at random from the inspection lot. Randomness in this instance means that every package in the lot has an equal chance of being selected as part of the sample. It does not matter what other packages have already been chosen, what the package net contents are, or where the package is located in the lot. To obtain a random sample, two steps are necessary. First it is necessary to identify each package in the lot of packages with a specific number whether on the shelf, in the warehouse, or coming off the packaging line. Then it is necessary to obtain a series of random numbers. These random numbers indicate exactly which packages in the lot shall be taken for the sample. The Random Number Table The random number tables in Appendix B are composed of the digits from 0 through 9, with approximately equal frequency of occurrence. This appendix consists of 8 pages. On each page digits are printed in blocks of five columns and blocks of five rows. The printing of the table in blocks is intended only to make it easier to locate specific columns and rows. Random Starting Place Starting Page. The Random Digit pages numbered B-2 through B-8.
  • Effects of a Prescribed Fire on Oak Woodland Stand Structure1

    Effects of a Prescribed Fire on Oak Woodland Stand Structure1

    Effects of a Prescribed Fire on Oak Woodland Stand Structure1 Danny L. Fry2 Abstract Fire damage and tree characteristics of mixed deciduous oak woodlands were recorded after a prescription burn in the summer of 1999 on Mt. Hamilton Range, Santa Clara County, California. Trees were tagged and monitored to determine the effects of fire intensity on damage, recovery and survivorship. Fire-caused mortality was low; 2-year post-burn survey indicates that only three oaks have died from the low intensity ground fire. Using ANOVA, there was an overall significant difference for percent tree crown scorched and bole char height between plots, but not between tree-size classes. Using logistic regression, tree diameter and aspect predicted crown resprouting. Crown damage was also a significant predictor of resprouting with the likelihood increasing with percent scorched. Both valley and blue oaks produced crown resprouts on trees with 100 percent of their crown scorched. Although overall tree damage was low, crown resprouts developed on 80 percent of the trees and were found as shortly as two weeks after the fire. Stand structural characteristics have not been altered substantially by the event. Long term monitoring of fire effects will provide information on what changes fire causes to stand structure, its possible usefulness as a management tool, and how it should be applied to the landscape to achieve management objectives. Introduction Numerous studies have focused on the effects of human land use practices on oak woodland stand structure and regeneration. Studies examining stand structure in oak woodlands have shown either persistence or strong recruitment following fire (McClaran and Bartolome 1989, Mensing 1992).

  • Call Numbers

    Call Numbers

    Call numbers: It is our recommendation that libraries NOT put J, +, E, Ref, etc. in the call number field in front of the Dewey or other call number. Use the Home Location field to indicate the collection for the item. It is difficult if not impossible to sort lists if the call number fields aren’t entered systematically. Dewey Call Numbers for Non-Fiction Each library follows its own practice for how long a Dewey number they use and what letters are used for the author’s name. Some libraries use a number (Cutter number from a table) after the letters for the author’s name. Other just use letters for the author’s name. Call Numbers for Fiction For fiction, the call number is usually the author’s Last Name, First Name. (Use a comma between last and first name.) It is usually already in the call number field when you barcode. Call Numbers for Paperbacks Each library follows its own practice. Just be consistent for easier handling of the weeding lists. WCTS libraries should follow the format used by WCTS for the items processed by them for your library. Most call numbers are either the author’s name or just the first letters of the author’s last name. Please DO catalog your paperbacks so they can be shared with other libraries. Call Numbers for Magazines To get the call numbers to display in the correct order by date, the call number needs to begin with the date of the issue in a number format, followed by the issue in alphanumeric format.

This led them to an absorption with the Jewish creation myths in Genesis, which they obsessively reinterpreted to formulate allegorical explanations of how humans ended up trapped in the world of matter. The basic Gnostic story, which varied in details from teacher to teacher, was this: In the beginning there was an unknowable, immaterial, and invisible God, sometimes called the Father of All and sometimes by other names. “He” was neither male nor female, and was composed of an implicitly finite amount of a living nonphysical substance. Surrounding this God was a great empty region called the Pleroma (the fullness). Beyond the Pleroma lay empty space. The God acted to fill the Pleroma through a series of emanations, a squeezing off of small portions of his/its nonphysical energetic divine material. In most accounts there are thirty emanations in fifteen complementary pairs, each getting slightly less of the divine material and therefore being slightly weaker. The emanations are called Aeons (eternities) and are mostly named personifications in Greek of abstract ideas.
