Margaret Chase Smith’s Speech of a Lifetime

The American experiment was founded on the idea of a democracy where the people hold the ultimate power over the government. But when the government oversteps its power; when it threatens to endanger individual rights, it takes someone with true courage to stand up for the America public. Some of the most striking examples of blatant abuse of power in the last century occurred during the Cold War. From 1947 to 1991, the Capitalist United States (US) and the Communist Union of Soviet Socialist Republics (USSR) clashed in a series of escalating economic and political tensions. In the midst of this tumultuous period, US government officials became concerned that communist sympathizer would collude with Soviet spies and endanger national security. The most vocal advocate for the “Red Scare” was Republican Senator Joseph McCarthy of Wisconsin. McCarthy came under the national spotlight during his speech in Wheeling, West Virginia, when he claimed that 205 State Department employees were known communist infiltrators (Achter). Although he lacked definitive evidence to back his claim, McCarthy continued a long string of accusations against celebrities, politicians, and nearly anyone who disagreed with him. McCarthy’s campaign to “expose” communist infiltrators caused innocent Americans to lose their careers and reputations, and fueled McCarthy’s rise to power. This period of mass, unsubstantiated paranoia eventually became known as “McCarthyism” (Achter). Few dared to challenge him, for fear of becoming his next target; At least not until a woman by the name of Margaret Chase Smith stepped into the political fray.

Why Are Some Beetles Shiny and Attracted to Light?

To answer this question we will first have to review the physical properties of light and go over the basics of optics, which is the study of the relationship between sight and light. Visible light is a section of the electromagnetic spectrum, and it is the only portion that people can see. While electromagnetic radiation can be measured via its various prosperities, such as frequency or energy, it is most commonly categorized by wavelength. Taking one step back, radiation is the transfer of energy in the form of waves or particles. For electromagnetic radiation, wavelength is determined by measuring photons. Put simply, photons are massless particles that also exhibit the characteristics of waves. To measure wavelength a point is designated on one wave (usually a peak or trough) and the length between it and that same point on the next wave gives you the wavelength.

Psychology and Marketing of Eating: Why Do We Eat the Way We Do?

The overwhelming amount of commercials, advertisements, and promotional campaigns that Americans are bombarded with is astronomical, to the point it is affecting their dietary habits. As the turn from a nomadic lifestyle switched to one with steady food supplies and surplus, history of mankind derailed and took an entirely different course, one that would later involve corporations utilizing marketing communications to influence their consumers.

Education in the 1930s Depression Facts and John Dewey “Father of Modern Education”

ntroduction: The Depression was a terrible time for the American economy, and patriotic morale for democracy was low for the people. Thus, education received dwindling funds, and many schools were closed. Nevertheless, “every cloud has a silver lining” was true during the Depression because the lacking education resulted in the social opinions given by education advocate John Dewey, and uniquely enough, higher literacy rates among school children.    

Sacred Figs Facts and Symbolism of Trees in Dreams

Trees figure into the stories and symbols of religions across the world. In Norse mythology the ash tree Yggdrasil connects and supports the nine realms. Drawing from this and other traditions, various neopagan movements value, among other things, environmentalism for both secular and spiritual reasons. As for North America, trees and other plants are central to the Medicine practices of several tribes. The cedar tree even appears on the Medicine Wheel important to certain sacred rites, with the associated cardinal direction of the tree varying between different tribes. Cedar also figures into the religion of ancient Mesopotamia, forests of cedar being where their gods dwelled. That trees play a part in these and many other belief systems suggests that they have a fundamental appeal. In addition to being common components of many natural landscapes, trees are tall, sometimes imposing, and occasionally majestic. That people would attach and associate the reverence they feel toward religious subjects to these statuesque plants makes a lot of sense. In the past and up to the present, several religions have struck upon the same idea before encountering one another, the idea of a world tree. World trees are a type of axis mundi (world axis), a sort of pillar that conjoins or bridges the material and the spiritual. Yggdrasil is one example of this, and there are others as well. Beyond ashes and cedars, there are many other trees with sacred heritages. Notable among these are two varieties of fig.

The Little Ice Age: Definition, History, Causes, and Ending of the Ice Age

Earth has experienced at least five Ice Ages: the Huronian, the Cryogenian, the Andean-Saharan, the Karoo, and the Quaternary. The latest of these is the Quaternary Ice Age, which began 2.6 million years ago and is still ongoing. That might sound off given that the popular conception of an ice age is of a world blanketed in snow and roaming with wooly mammoths, but the scientific definition only requires that a substantial ice sheet be present on the Earth’s surface, and Antarctica fits the bill. While their causes vary, ice ages are typified by periods of sustained global cooling and glacial expansion. Going by this, the Little Ice Age qualifies, though it is also an ice age within an ice age, making it a sort of matryoshka doll climate event. The Little Ice Age is not the only lesser ice age, though it is the best known as it occurred the most recently and within recorded history. After having touched on similarities, our next logical step is to examine what makes the Little Ice Age different.

The Life Cycle of a Retrovirus: HIV

Retroviruses are a class of viruses that not only infect host cells but also integrate their genetic material into the host genome, establishing a permanent infection that cannot be cured. The most common retrovirus is the human immunodeficiency virus or HIV, which targets and destroys helper T-cells.

What is Maladaptive Daydreaming Disorder?

Daydreaming is a common human phenomenon, one that we all experience in our daily lives. Studies show that we actually spend around 47% of our waking time in the dream world. We utilize this important tool to think-out different scenarios, re-visit special times in our lives, imagine new ones, or even just to pass time. Daydreaming is vital to the human experience. But one may wonder, what happens when one daydreams a little too much?

Embryogenesis: Definition, Stages, and Development [MCAT]

Sonic Hedgehog Gene. CNS development and Limb development. In embryology and developmental biology, embryogenesis is the development of an animal or plant embryo, starting with fertilization of an egg cell by a sperm cell. After fertilization, the ovum becomes a diploid zygote. orms forebrain, separates right and left brain, and establishes midline. f there’s a mutation, then we have a whole brain with no separation of right and left, which is bad. This is called holoprosencephaly. Left and right hemispheres fail to separate. There are also facial abnormalities, cleft lip/palate and even severe cyclopia (single eye like a cyclops).
