• How
did a book become a turning point in Richard Ebright’s life?
Answer:
The
book gifted by his mother entitled ‘The Travels of Monarch X’ was something
that he found very interesting because by then he himself had collected
different species of butterflies. And this book happened to explain how monarch
butterflies made Central America their home. He became way more interested in
science, and it paved the way for many discoveries he did later in his life.
• How
did his mother help him?
Answer:
Enright's mother was a great source of motivation for Richard. She even took
him for scientific trips and never refused a piece of scientific equipment that
she knew would benefit her kid. She bought him telescopes, mounting materials,
etc. Her hello was not always direct. For example, once she gave him a book
entitled 'The Travels of Monarch X', and the book became a turning point in
Ebright's life.

• What
lesson does Ebright learn when he does not win anything at a science fair?
Answer:
Ebright learns that in order to win a prize he had to focus on conducting real
experiments.
• What
experiments and projects does he then undertake?
Answer:
While in his eighth grade, Ebright tries to figure the cause of a viral disease that has been taking the lives
of monarch caterpillars every few years. He also happened to investigate the
bright spots that could be seen on the monarch pupa, eventually finding out
that it was an unknown insect hormone that caused this. This also led to his
propounding the new theory on the life of cells besides how cells read their
DNA.
• What
are the qualities that go into the making of a scientist?
Answer:
First-rate mind, curiosity and the will to perform the best, thus winning for
the right reasons are the qualities that go into the making of a scientist.
