Roentgen shares part of his academic path with Albert Einstein: they each won entrance to Zurich
Polytechnical School by examination. What disqualified both of these scientists from the traditional
enrollment path? - correct answers ✔✔disobeyed the authority of educators
What personal attributes or capabilities enhance Roentgen's chances of his scientific discoveries? -
correct answers ✔✔- good with his hands
- meticulous experimenter
- rigid and stubborn, although not lacking imagination or daring
- spent endless hours in the lab
T or F: Roentgen discovered X-rays on Nov 8, 1895. For the subsequent 6 weeks, he performed a series of
experiments to characterize the distance that, and substances through which, X-rays traveled, skipping
meals to focus on documenting the novel discovery. His findings were published within 7 weeks and a
day by the physical and Medicine Society of Wurzberg. However, it took several years, still, for clinicians
to start using the technology. - correct answers ✔✔false - xrays were embraced immediately
Describe some underlying personal motivations for Sigmund Freud that you read? - correct answers ✔✔-
His mother adored him and gave him the sense that "he was born to achieve something great" which
gave him the confidence to succeed later in life.
- His father, on the other hand, said the he would "never amount to anything" and Freud still had dreams
decades later of proving his father wrong by speaking his accomplishments.
How does the work of Freud and Weyer connect? Is there a difference in cultural response between
these two time periods? - correct answers ✔✔Both Freud and Weyer's work was focused on human's
mental state and brain function. Specifically, they both focused on psychiatric problems, such as hysteria,
to explain the very real symptoms of mental illness. In Weyer's time, people and women specifically
were seen as crazy and tortured for their mental condition. In Freud's time though, these problems were
legitimized and became proper subjects in medical study.
,One technique that Freud and colleague Breuer became known for is "catharsis", which refers to the
process of "tracing [hysterical symptoms back to their] first appearance and re-experiencing the
associated thoughts and feelings" that were experienced the first time. Through catharsis, many clients
were able to stop the symptoms from occurring ever again, essentially curing the "hysteria". This process
was given a different name by "Anna O.", the first patient who Breuer tried it with. What did she call it? -

In one word, what scientific/medical first is attributed to Ivanovsky? The discovery of: - correct answers
✔✔viruses
In 3-4 sentences, tell the story of how Ivanovsky figured out this innovation. - correct answers
✔✔Ivanovsky was analyzing stunted, discolored tobacco plants that he recognized were infected by
tobacco mosaic disease. He set out to isolate the microbe that he assumed was causing the disease, but
when juice from the infected leaves was put into a filter for bacteria, the agent that spread the disease
slipped through the filter which meant the microbe had to be something he couldn't see. After reading
Beijerink's discoveries that ruled out bacterial spores, toxins, or particles, Ivanovsky believed that the
most likely explanation for these filterable viruses was that "the contagium is contained in the sap in the
form of solid particles."
In 3-4 sentences, give your impression of Ivanovsky as a scientist and as a person. Address a different
impression or character trait of Ivanovsky per sentence (no repetition of information between sentences.
- correct answers ✔✔Ivanovsky seemed like he was methodical in the steps of his experiment:
recognizing the tobacco disease, pumping the juice through the filter, and used his findings to make
assumptions based on what was known in the world of medicine. He also seemed territorial of his
findings: he wrote to claim priority for the discovery that the agent could pass through the filter and
criticized Beijerinck's agar experiment. He was also open and imaginative to this new disease-causing
agent: it was too small to see with the naked eye and not a known bacteria or toxin that caused the
disease.
In 3-4 sentences, describe Fleming's "firsts"--his advances and discoveries. - correct answers ✔✔His first
discovery was that by surgically removing as much dead tissue as possible and flushing the wounds of
soldiers with sterile saline solution, infection was greatly minimized and the production of white blood
cells was stimulated. His second discovery was that droplets of nasal mucus were destroying a yellowish
bacterial colony in some contaminated culture plates and identified the substance killing the bacteria as
a protein called lysozyme. His other discovery was of the powerful broad-spectrum antibacterial
substance penicillin, which he came across in his lab when he noticed on a petri dish that the staph
colonies close to mold had dissolved. He discovered the mold was secreting something that killed many
of the disease-causing bacteria even as it was diluted, now known as penicillin.
, In a 3-4 sentences, describe the cultural and historical context of Fleming's life and work. - correct
answers ✔✔When World War I broke out, Fleming went to France to treat wounded soldiers where he
discovered antisepsis methods were not working for sever wounds of the soldiers. Thousands of soldiers
were dying of tetanus, blood poisoning, and gangrene. Flemings approach to surgically remove dead
tissue and flush the wound with saline was resisted within the army. His discovery of lysozyme and
penicillin were both ignored and dismissed by his colleagues.
In 3-4 sentences, talk about your impressions of Fleming as a scientist and a person - correct answers
✔✔My impressions were that Fleming was a quiet and modest yet driven and brilliant man who was
confident in his remarkable discoveries. He seemed as though he had conflicting personalities as a
scientist and as a person. As a scientist, he was said to be a leader, always at the top of his class,
observant, and experimental. As a person, he was said to be a sports lover, as well as modest, shy, and
inscrutable.
T or F: Margaret Sanger coined the term "birth control" - correct answers ✔✔true - She first used the
term in the June 1914 issue of a newspaper she founded: called "The Woman Rebel".
T or F: Magaret Sanger created the birth control pill (The Pill). - correct answers ✔✔false - Sanger was a
leading advocate for birth control. Katherine Dexter McCormick provided the financial backing. Sanger
recruited Gregory Pincus and John Rock, experimental scientists, to developed the product.
T or F: Sanger, who was a practicing nurse, was jailed for distributing information about birth control to
her clients. - correct answers ✔✔true - Sanger was sentenced to 30 days in jail for providing information
about birth control because it was illegal in her time.
