Evidence for a Non-Expanding Universe: Surface Brightness Data From HUDF

Surface brightness data can distinguish between a Friedman-Robertson-Walker expanding universe and a non-expanding universe. For surface brightness measured in AB magnitudes per angular area, all FRW models, regardless of cosmological parameters, predict that surface brightness declines with redshift as (z+1)^-3, while any non-expanding model predicts that surface brightness is constant with distance and thus with z. High-z UV surface brightness data for galaxies from the Hubble Ultra Deep Field and low-z data from GALEX are used to test the predictions of these two models up to z=6. A preliminary analysis presented here of samples observed at the same at-galaxy wavelengths in the UV shows that surface brightness is constant, mu=kz^0.026+-0.15, consistent with the non-expanding model. This relationship holds if distance is linearly proportional to z at all redshifts, but seems insensitive to the particular choice of d-z relationship. Attempts to reconcile the data with FRW predictions by assuming that high-z galaxies have intrinsically higher surface brightness than low-z galaxies appear to face insurmountable problems. The intrinsic FUV surface brightness required by the FRW models for high-z galaxies exceeds the maximum FUV surface brightness of any low-z galaxy by as much as a factor of 40. Dust absorption appears to make such extremely high intrinsic FUV surface brightness physically impossible. If confirmed by further analysis, the impossibility of such high-surface-brightness galaxies would rule out all FRW expanding universe (big bang) models.Comment: 16 pages, 9 figures, to be published in the Proceedings of the First Crisis in Cosmology Conference, AIP proceedings series typos correcte

Fearless: Eric Lee

Snapping pictures of his fellow Gettysburgians around campus as the visual communications intern, and fearlessly working with other students to create, organize, and lead the new Asian Student Alliance (ASA) group on campus, Eric Lee ’15 finds himself at the crossroads of art and activism. New to campus this year after two years in the making, the ASA is a student-led, -run, and -organized group focused on celebrating different Asian cultures and heritages, closing the gap between international and domestic students, and creating a social, cultural, and political forum for students to dialogue, specifically about issues facing Asian communities.

A Study of the Effects of Foreign Direct Investment on the Economy of the State of New Hampshire Since 1973

The purpose of the thesis is to determine the impact that foreign direct investment has had on New Hampshire. New Hampshire as a state was impacted far less severely than much of the rest of the country, which could be considered surprising given the relatively high cost of housing in the state. I believe that part of what made New Hampshire more recession resistant is having the right foreign companies providing employment. To do this, I will be looking at FDI as a percentage of GDP over the previous 40 years and looking for a correlation between a higher percentage and national recession. I will also look at specific foreign corporations that lend the most to the New Hampshire economy to obtain a more specific view of the impact such companies have on both their communities and the state as a whole. This data could prove useful to New Hampshire as well as other states looking to protect against recession, as well as corporations looking to justify FDI to various governments

Nature or Nurture? The Concentration of African Americans in Specific Sports

The prevalence of African Americans in certain American professional sports is certainly evident. Their prevalence is particularly pertinent and commonly associated with sports such as basketball, football, and track. The percentage of the players in the National Basketball AssociatIon (NBA) that were African American in the 2017-2018 season was 73.9% (Lapchik, 2018). Additionally, the percentage of players that were African American in the National Football League (NFL) during the 2016-2017 season was 69.7% (Lapchik, 2018). These statistics however differ from proportions of African Americans representing these respective sports at the Division I college level. The percentage of African Americans at the Division I college level in basketball is 53% and 44.2% in football (Lapchik, 2017). These statistics clearly show that African Americans represent the majority of the players in these respective sports at a professional level, a subject that is often discussed and debated. Often times these discussions extend further as to why African Americans represent the majority of these leagues. There are two prominent theories as to why African Americans represent the majority of players in certain sports, such as football and basketball; one attributing it to their genetics and other attributing to their environment. This paper will articulate on the two prominent theories that offer explanations as why African Americans constitute the majority in specific sports. Furthermore, this paper will analyze the theory that suggests that their athletic abilities and prevalence in certain sports is attributed to genetic differences; and use research to discredit such claims. Additionally, this paper will offer explanations as to how this notion has come into existence and how has sustained. Ultimately, this paper will illustrate the importance of the environment when analyzing the representation of African Americans in certain sports, and how these different atmospheres interact with one another

Energy Flows in Low-Entropy Complex Systems

Nature's many complex systems--physical, biological, and cultural--are islands of low-entropy order within increasingly disordered seas of surrounding, high-entropy chaos. Energy is a principal facilitator of the rising complexity of all such systems in the expanding Universe, including galaxies, stars, planets, life, society, and machines. A large amount of empirical evidence--relating neither entropy nor information, rather energy--suggests that an underlying simplicity guides the emergence and growth of complexity among many known, highly varied systems in the 14-billion-year-old Universe, from big bang to humankind. Energy flows are as centrally important to life and society as they are to stars and galaxies. In particular, the quantity energy rate density--the rate of energy flow per unit mass--can be used to explicate in a consistent, uniform, and unifying way a huge collection of diverse complex systems observed throughout Nature. Operationally, those systems able to utilize optimal amounts of energy tend to survive and those that cannot are non-randomly eliminated.Comment: 12 pages, 2 figures, review paper for special issue on Recent Advances in Non-Equilibrium Statistical Mechanics and its Application. arXiv admin note: text overlap with arXiv:1406.273
