Foot Prints Without Feet Supp. Reader
Alright class, let's delve into Chapter 6, 'The Making of a Scientist'. This chapter traces the journey of Richard H. Ebright, a brilliant scientist, highlighting the factors and experiences that shaped his path. Pay close attention, as understanding his development is key, especially for objective questions in exams.

Chapter 6: The Making of a Scientist - Detailed Notes

1. Introduction:

  • The chapter focuses on the life and development of Richard H. Ebright, a renowned molecular biologist.
  • It explores how his childhood curiosity, nurtured by his mother and specific experiences, led him to a successful scientific career.
  • It emphasizes that becoming a scientist involves more than just intelligence; it requires curiosity, persistence, a competitive spirit (in the right sense), and guidance.

2. Richard H. Ebright - The Protagonist:

  • A bright child from Reading, Pennsylvania.
  • Grew up as an only child after his father's death when he was in third grade.
  • His primary companion and source of encouragement was his mother.

3. Early Life and Developing Curiosity (Pre-Butterflies):

  • Ebright had an inherent curiosity from a young age.
  • He engaged in collecting various items: rocks, fossils, and coins.
  • He was also an eager astronomer, sometimes stargazing all night.

4. The Turning Point - Butterflies and "The Travels of Monarch X":

  • His interest shifted significantly towards butterflies, especially after his mother introduced him to the subject.
  • A pivotal moment was when his mother gifted him a children's book called "The Travels of Monarch X".
  • This book described the migration of monarch butterflies to Central America and invited readers to participate in butterfly research by tagging them for Dr. Frederick A. Urquhart of the University of Toronto, Canada.

5. The Butterfly Tagging Project:

  • Ebright started tagging monarch butterflies found in his hometown.
  • He would catch a female monarch, take her eggs, raise them through their life cycle (caterpillar, pupa, adult butterfly) in his basement, and then tag the adults' wings before releasing them.
  • Initially, this work didn't yield much feedback or results, making him feel it was tedious. Only two tagged butterflies were ever recaptured, and not very far away.

6. The County Science Fair - Learning from Failure:

  • Grade 7: Ebright entered the county science fair with slides of frog tissues under a microscope. He didn't win any prize.
  • Realization: He understood that winners had tried to conduct real experiments, whereas he had simply made a neat display. This was a crucial learning experience.
  • This failure spurred him to pursue actual scientific inquiry.

7. Moving Towards Real Experiments:

  • Grade 8 Project: Inspired by Dr. Urquhart, Ebright tried to find the cause of a viral disease that killed nearly all monarch caterpillars every few years. He hypothesized the disease might be carried by beetles and raised caterpillars in the presence of beetles. He didn't get definitive results but showed his effort at experimentation and won a prize.
  • Grade 9 Project: He tested the theory that viceroy butterflies copy monarch butterflies because monarchs don't taste good to birds, thus protecting the viceroys. His experiment involved seeing if starlings (birds) would eat monarchs. He found they would eat monarchs, suggesting the viceroy likely copies the monarch for other reasons (later research showed viceroys also taste bad). This project won him prizes at the county and state science fairs.

8. The Gold Spots Mystery - A Major Breakthrough:

  • Sophomore Year (High School): Ebright questioned the purpose of the twelve tiny gold spots on a monarch pupa. Most scientists believed they were purely ornamental.
  • Experiment: Along with another student, he built a device that showed the spots were producing a hormone necessary for the butterfly's full development.
  • Significance: This project won first place at the county fair and entry into the International Science and Engineering Fair (ISEF), where it won third place for zoology.

9. Advancing Research - Hormones and Cell Biology:

  • Junior Year: Ebright continued his experiments on the gold spot hormone. He identified the hormone's chemical structure.
  • Senior Year: While looking at X-ray photos of the hormone's chemical structure, he got the idea for his new theory about cell life.
  • The Theory: He realized how cells could 'read' the blueprint of their DNA. DNA is the substance in the nucleus of a cell that controls heredity. It determines the form and function of the cell. This discovery could lead to understanding processes like cancer and other diseases.

10. University and Beyond:

  • Ebright graduated from Harvard with highest honours, second in his class of 1,510.
  • He continued his research at Harvard Medical School.
  • His work on how cells work was published in the prestigious scientific journal 'Proceedings of the National Academy of Science' – a rare achievement for a college student.

11. Key Influences:

  • His Mother: Played a crucial role. She encouraged his interests, took him on trips, bought him scientific equipment (telescope, microscope, camera, mounting materials), provided intellectual companionship, and gave him the book "The Travels of Monarch X."
  • Dr. Frederick A. Urquhart: His research project on monarch migration provided Ebright with his first real scientific task (tagging).
  • Mr. Richard A. Weiherer: His social studies teacher and advisor to the debating and model UN clubs. He admired Ebright's energy, dedication, and competitive spirit (wanting to do his best), and helped channel it positively. Mr. Weiherer opened Ebright's mind to new ideas.

12. Qualities of Richard Ebright:

  • Curiosity: The driving force behind his explorations.
  • Persistence/Perseverance: Continued tagging butterflies despite limited feedback; pursued experiments even after initial failures or inconclusive results.
  • First-rate Mind: Possessed sharp intellect.
  • Competitive Spirit (Positive): Not for the sake of winning prizes, but for doing the best job he could.
  • Well-Rounded: Not just interested in science; he was also a champion debater, a good public speaker, a skilled canoeist, and an expert photographer (especially of nature and science exhibits).
  • Attention to Detail: Necessary for careful observation and experimentation.
  • Willingness to Learn: Learned from the science fair failure and adapted his approach.

13. Conclusion/Theme:

  • The chapter illustrates that becoming a successful scientist requires a blend of innate curiosity, intelligence, nurturing support (like from his mother), exposure to real scientific problems (like Dr. Urquhart's project), learning from failures, persistence, and a drive to be the best. It shows the step-by-step process of scientific inquiry, starting from simple observation and moving towards complex experimentation and theory building.
