...ASTR 122 05/13/2013 Assignment #3 951131748 WangJae Lee Astronomy 122 Distance Education Third Homework Assignment 1. Explain why measuring parallax distances for only the brightest appearing stars in the sky would give you a biased luminosity scale and an unrepresentative sample of stars. -The stellar parallax measures the relative distances from stars to different positions of the Earth in order to measure luminosity. It is done by using distant stars as a fixed reference system so that if a star is observed in respect to the distant stars today, and then measured again in six months, a small shift in movement will be recorded. It is absolutely necessary for there to be “distant stars” or less bright stars as a frame of reference otherwise the angle measurements would have nothing to compare against. Thus, it creates a biased scale of recorded luminosity. 2. Explain the overall concept of pressure support (against gravity) in stars and why stars are unstable if they are not generating energy in their cores. -The concept of pressure support can be explained through the internal gas pressure. The internal gas pressure is attempting to expand and dissipate our ball of gas, while the self-gravity of the gas (due to its mass) is trying to collapse the ball. As the gas gets hotter, the internal gas pressure increases. Then, it reaches a point of stabilization between gravity and pressure support. -Stars are unstable if they are not generating energy in their cores because...

...Jorge Fabela Professor Scott Bulkley ASTR 1 February 24, 2015 Sky Journal Entry 3 Today is February 24, 2015 and this is sky journal #4. The time reads 6:48 p.m. and the whole classroom is going to the observatory. Just before I go in I did this sky journal. The Moon’s phase is waxing crescent and very bright. The location of the moon is 80° SW. The planets that I found were Venus, Mars, and Jupiter again. With a very bright white light Venus is located about 20°-25° SW. Mars as usual this month is really close to Venus just about 1° NE of Venus. Mars location is about 18°-23° SW and blinking a shiny red. Jupiter on the other hand is just rising. The time reads 6:57 p.m. and it’s located about 45° E. The constellations that I found were LEO MINOR, CEPHEUS, and CASSIOPIA. I located LEO MINOR about in the NE sky about 7:01p.m. It’s about approximately 35°-40° degrees NE. CEPHEUS “the weird looking house” is in the Northern sky about 35° N. CASSIOPIA “the big M/W of the sky” was found about 45° NW. Very visible and bright in the sky. Although there were more constellations these ones caught my attention. I got to say the way the moon looked in the observatory was fascinating totally different than the way we see it up at night. With that I must say that the telescope was ginormous and it made me see the moon like it was a cell with all the craters and different shapes. It makes one wonder how did it happen. Well that makes 3 sky journals 7 more to...

...ASTR PTYS 206 Dr. Kortenkamp September 3, 2013 HW2 _ Aristarchus The size of the Sun compared to the size of the Moon is a big difference. The Sun and the Moon look to be the same size, but it is deceiving because they are nowhere close to being the same size. The Sun is 1,392,000 kilometers across and the moon is 1,737 kilometers. So about ten moons can span across the width of the Sun. The Moon and the Sun are at two difference distances from the Earth. The Moon is about 384,400 kilometers from the Earth and the Sun is 149,600,000 kilometers from the Earth. The Earth is smaller then the Sun, but larger then the Moon. In the picture below, the cacti look like they are all the same size. When you are standing right next to the cacti that are father way they are actually all different sizes. It is like looking at the Sun...

...ASTR 101 12 June 2016 Humans Will Not Survive It is only a matter of time before the cosmic calendar catches up to our species, as it had with the dinosaurs. Admittedly, our species has made leaps and bounds as a civilization despite the short amount of time that we have spent on the cosmic calendar. However, the human species has been around for only the last half-minute on the cosmic calendar, and we might not last much longer (Bennett, 2014). Even world renown physicist Steven Hawking has placed an expiration date on the human species. Steven Hawking has given us 100 to 200 more years to live out our last years unless we start branching out and inhabiting other planets. Hawking even went so far as to say, “If we can avoid disaster for the next two centuries, our species should be safe as we spread into space (Cosmic Log, 2010).” It is no secret that our planet’s temperature is slowly rising and that humans have the power to eradicate all life on earth with nuclear weapons. If we don’t die of nuclear warfare, or of global warming, an asteroid or nearby supernova just might do the trick (Big Think, 2015). Many, many scientists and space enthusiast have come to the same conclusion that we have all of our eggs in one planetary basket, and that we need to spread them out amongst other planets if we ever hope to outlast the dinosaurs on the cosmic calendar (Cosmic Log, 2010).

... The farthest location away from the main land mentioned in the Veda is ‘Kandhar’ of present day Afganistan which has been named Gnadhar in Vedic text. None of the Vedic text talks about rivers outside India. It is an established fact that rivers are the life giving force of all ancient civilizations and ancient people have remained very much grateful to these rivers. So, it is a proven fact that the divide policy has never worked in ancient India before the Britishers’ criminal act of dividing. It is also a proven fact that astro-geographical conditions of India are bountiful and peoples from the land of destitution have flocked to India at historical intervals before the modern machine production and service and the digestive power of astr-geographical conditions of India is so strong that it has digested Huns-Shaky- Kushan- Parthian- Bactrian, Islamists and Christians and all who have come to India for their livelihood.

Fine Theoretical Physics Institute, School of Physics and Astronomy, University of Minnesota, Minneapolis, MN 55455 USA E-mail: olive@umn.edu Observational evidence and theoretical motivation for dark matter are presented and connections to the CMB and BBN are made. Problems for baryonic and neutrino dark matter are summarized. Emphasis is placed on the prospects for supersymmetric dark matter. 1. Lecture 1 The nature and identity of the dark matter of the Universe is one of the most challenging problems facing modern cosmology. The problem is a long-standing one, going back to early observations of mass-to-light ratios by Zwicky1 . Given the distribution (by number) of galaxies with total luminosity L, φ(L), one can compute the mean luminosity density of galaxies L= which is determined to be2 L ≃ 2 ± 0.2 × 108 ho L⊙ M pc−3 (2) Lφ(L)dL (1) where L⊙ = 3.8 × 1033 erg s−1 is the solar luminosity. In the absence of a cosmological constant, one can define a critical energy density, ρc = 3H 2 /8πGN = 1.88 × 10−29 ho 2 g cm−3 , such that ρ = ρc for three-space curvature k = 0, where the present value of the Hubble parameter has been defined by Ho = 100ho km Mpc−1 s−1 . We can now define a critical mass-to-light ratio is given by (M/L)c = ρc /L ≃ 1390ho(M⊙ /L⊙ ) (3) ∗ Summary of lectures given at the Theoretical Advanced...

...Project Report TOPIC: “REMOTE IT Infrastructure Management ” 1. Abstract The recently launched NASSCOM-McKinsey Report 2006 yet again reaffirmed views of the global gurus that Remote Infrastructure Management (RIM) Services are all set to become the next star of the Indian IT Industry. It clearly states that “going forward, the more traditional IT outsourcing service lines such as hardware and software maintenance, network administration and help desk services will account for 45 per cent of the total addressable market for offshoring and are likely to drive the next wave of growth. . Service lines that have driven recent growth, i.e., application development and maintenance (ADM) and R&D services are already 30-35 % penetrated and are not as likely to grow dramatically”. The Remote/offshore part was easy with BPO having already paved the way for proving service delivery effectiveness from an offshore location and with the advent of sophisticated tools and technologies that enabled remote IT management the proposition was further solidified. International research firm IDC also declared that “more than 85% of infrastructure components can be managed from a central remote location. These components encompass servers/systems, databases, networks, storage, security, applications and e-business infrastructure. Through managing these components from a remote location, companies can cut down their cost of infrastructure operations and management by 40-60 %, also gaining access...
