Climate Change and the Ross River Virus Climate change may be a politically contentious issue‚ but the scientific community has reached a consensus: it is real and the effects could be disastrous (Hughes‚ 2003). Within the next century‚ there will be changes in rainfall patterns‚ rising sea-levels and significant temperature increases‚ as well as the impact these conditions will have on flora‚ fauna and disease transmission (Hughes‚ 2003). Of particular concern to Australia is how these changes

The four color theorem is a mathematical theorem that states that‚ given a map‚ no more than four colors are required to color the regions of the map‚ so that no 2 regions that are touching (share a common boundary) have the same color. This theorem was proven by Kenneth Appel and Wolfgang Haken in 1976‚ and is unique because it was the first major theorem to be proven using a computer. This proof was first proposed in 1852 by Francis Guthrie when he was coloring the counties of England and realized

This August‚ a friend of mine who is passionate about climate change and food justice recommended to me the documentary Cowspiracy because it played a huge role in her becoming a vegan. I watched it with my mom‚ and both of us immediately became vegetarians. The documentary discussed‚ analyzed‚ and brought to light animal agriculture’s significant role in climate change. I used to love meat—particularly hamburgers and bacon—but the evidence that the film presented on animal agriculture’s impact on

movements of energy like wind and precipitation. Climate is the generally prevailing weather patterns of a region. The climate of a region is made up of the different weather patterns. The weather patterns are usually repetitive according to the seasons. Where I’m from in southwest Nebraska it snows in the winter‚ rains in the spring‚ and is hot in the summer. The question is‚ has the weather and climate always been like this in Nebraska? We have proof that climate has changed in the past. Seventy million

1 10/10/01 Fermat’s Little Theorem From the Multinomial Theorem Thomas J. Osler (osler@rowan.edu) Rowan University‚ Glassboro‚ NJ 08028 Fermat’s Little Theorem [1] states that n p −1 − 1 is divisible by p whenever p is prime and n is an integer not divisible by p. This theorem is used in many of the simpler tests for primality. The so-called multinomial theorem (described in [2]) gives the expansion of a multinomial to an integer power p > 0‚ (a1 + a2 + ⋅⋅⋅ + an ) p = p k1 k2 kn a1 a2

“The Arrow impossibility theorem and its implications for voting and elections” Arrow’s impossibility theorem represents a fascinating problem in the philosophy of economics‚ widely discussed for insinuating doubt on commonly accepted beliefs towards collective decision making procedures. This essay will introduce its fundamental assumptions‚ explain its meaning‚ explore some of the solutions available to escape its predictions and finally discuss its implications for political

Climate change is controversial for a myriad number of reasons‚ but the main controversy is is it real. According to Sallie Baliunas‚ Ph.D. and Senior Scientist at George C. Marshall Institute‚ the warming of the earth is not due to human-made greenhouse gases. Furthermore‚ Baliunas asserts sunspots and the natural cycles of warming and cooling in the Pacific cause it. Baliunas makes this argument by deducing from from scientific studies‚ facts‚ and computer models; presenting the studies and models

People of higher power are calling on activists‚ and new laws are being made every day supporting this. Everywhere you go it’s all about energy effiency and new products being made that don’t give off CO2 emissions. It makes you wonder... does climate change really matter? Global warming is the increase of the earths average surface temperature caused by burning fossil fuels and releasing greenhouse gasses. Pretend the atmosphere is a decent blanket‚ not to thick not to thin‚ just good enough

a NOR gate. DeMorgan’s theorems state the same equivalence in "backward" form: that inverting the output of any gate results in the same function as the opposite type of gate (AND vs. OR) with inverted inputs De Morgan’s theorem is used to simplify a lot expression of complicated logic gates. For example‚ (A + (BC)’)’. The parentheses symbol is used in the example. _ The answer is A BC. Let’s apply the principles of DeMorgan’s theorems to the simplification of

A Brief History of the Pythagorean Theorem Just Who Was This Pythagoras‚ Anyway? Pythagoras (569-500 B.C.E.) was born on the island of Samos in Greece‚ and did much traveling through Egypt‚ learning‚ among other things‚ mathematics. Not much more is known of his early years. Pythagoras gained his famous status by founding a group‚ the Brotherhood of Pythagoreans‚ which was devoted to the study of mathematics. The group was almost cult-like in that it had symbols‚ rituals and prayers. In addition
