X-ray crystallography

His major discoveries came by doing experiments with cathode ray tubes which have electrons that emitted light when negative voltage and metal plates were added, this was the discovery of the electron or corpuscle as he named it (Unknown author, 1997). A cathode tube works by creating gaseous discharge, which "occurs…

at elevated temperatures. The images in this paper were obtained by the detection of secondary electrons that were emitted by atoms excited by the primary electron beam. The primary beam scans in a raster fashion, making horizontal passes across the x-axis one at a time. This allows the detector to display the information into the image on pixel at a time in synchronized manner. The number of secondary electrons that can be detected…

To demonstrate, “Malcolm X delivered "The Ballot or the Bullet" to a predominantly African-American meeting in… the Congress of Racial Equality …which was shifting from nonviolent protest to Malcolm X-like black nationalism. Helping provoke this shift were speeches like this one, which was received enthusiastically” (Miller). Many African Americans came to Malcolm’s speech because they really wanted to know what he meant by the “ballot” and “bullet”. By the end of his speech, Malcolm wanted that…

Malcolm X’s sense of urgency toward the civil rights situation at hand. Countless times in this address he calls to his fellow African Americans to inform themselves to the “ballot” or political atmosphere of their community. In place of violence, Malcolm X believes “that the black man should control the politics and the politicians in his own community”. He wants his fellow black citizens to better themselves and improve their communities using political knowledge, not aggression. This is the…

known is the more radical Malcolm X, whose stinging words generated significant controversy throughout his years of black activism. His militant singularity and hateful messages offered a stark contrast to the peaceful King as he tried to gain freedom for African Americans at any cost. Malcolm X’s harshly straightforward yet idiomatic style of speech combined with his nationalistic ideals to instill a powerful sense of cultural unity. The beliefs of Malcolm X were…

Since the start of filmmaking, sex has been a heavily debated topic, both on and off the screen. In the early 1970s, a kiss on screen or the mention of a sexual activity would be enough to convince parents to keep their children away. Not half a decade later, though, sexual acts were being displayed on camera for all to see, demonstrating a rapid progression in the acceptance of sexual acts over time in the film industry. Over time, a change has occurred in the regulation of content of American…

adulthood and start fighting for more jobs and better wages, then they will always be limited to living too much within their potential(source?) in every generation, there are always limitations, the baby boomers fought for civil rights and generation X fights for more control over their lives. Shari believes we should acquiesce to this demand and Beyak believes this as well. Will they (20-30 year olds) be…

Would it be possible to say that literacy can liberate someone, just like it did with Douglass and Malcolm? Frederick Douglass and Malcolm X were two African American men whom struggled in becoming literate. Frederick Douglass from the “Narrative of the life of Frederick Douglass, an American Slave”narrates how he struggled on learning how to read and write, being an slave and having such limited sources, Douglass tells the reader how his mistress, Mrs. Auld taught him the letters of the…

For a long time, older generations have liked to moan and bemoan about the younger generation. It has happened since at least the 1920s, when the new woman emerged and rejected the traditions of the Victorian era. Though this has almost become a “rite of passage” as said by Aaron Kaufman in “an Open Letter from a Millennial to Society,” it has made Millennials the “butt” of many mean jokes, and they have had to face many insults about how they are “the dumbest, laziest, most entitled,…

“A shiny unicorn on top of the flowery lawn” is what Lucy, a GYPSY, and others like her envision for themselves (Urban). A GYPSY, or a Generation Y Protagonist and Special Yuppie, is a middle to upper class citizen born between the late 1970s and the mid 1990s. All GYPSYs believe that they will be the best in their field because they are “special.” However, reality shows that this is not the case and that hard work is required to create and sustain a successful career, not just being told over…
