<strong>The</strong> <strong>Path</strong> <strong>to</strong> <strong>Nuclear</strong> <strong>Fission</strong> – <strong>The</strong> S<strong>to</strong>ry <strong>of</strong> <strong>Lise</strong> <strong>Meitner</strong> <strong>and</strong> Ot<strong>to</strong> Hahn<br />
Suggested Student Responses<br />
General Questions:<br />
1. Which Scientists are pictured as those working at the University <strong>of</strong> Berlin.?<br />
Albert Einstein, Gustav Hertz, Max Planck, James Franck <strong>and</strong> Max von Laue.<br />
2. Where does <strong>Lise</strong> <strong>Meitner</strong> come from <strong>and</strong> who does she work under in Berlin?<br />
She is Austrian <strong>and</strong> received her PhD in Physics from the University <strong>of</strong> Vienna in 1906. She<br />
works under Max Planck.<br />
3. What is Hahn’s his<strong>to</strong>ry <strong>and</strong> who does he come <strong>to</strong> work with in Berlin?<br />
He graduated in Chemistry from the University <strong>of</strong> Marburg in Germany <strong>and</strong> worked at<br />
McGill University in Montreal, Canada, under Ernest Rutherford before coming back <strong>to</strong><br />
Germany <strong>to</strong> work under the chemist Emile Fischer.<br />
4. What is Fischer’s <strong>and</strong> the other male scientists’ attitude <strong>to</strong> <strong>Meitner</strong>? How are women students<br />
treated generally at this time?<br />
Fischer would not let her work in the labora<strong>to</strong>ry in case she set her hair on fire. She worked<br />
in a room in the basement with a separate entrance. She received no salary <strong>and</strong> was ignored<br />
by the other scientists except Hahn.<br />
5. What are Hahn <strong>and</strong> <strong>Meitner</strong> studying?<br />
Every known substance that is a Beta emitter, <strong>and</strong> they discover several new ones.<br />
6. What is the Kaiser Wilhelm Institute? What are the roles <strong>of</strong> Fischer, Hahn <strong>and</strong> <strong>Meitner</strong>?<br />
A privately endowed institute, with a chemistry institute within it, in Berlin. It allows <strong>to</strong>p<br />
German scientists <strong>to</strong> work at an international level. Fischer is in charge <strong>of</strong> the chemistry<br />
institute <strong>and</strong> <strong>of</strong>fers Hahn a paid position as a scientific associate with the title <strong>of</strong> pr<strong>of</strong>essor.<br />
<strong>Meitner</strong> is expected <strong>to</strong> work with him but her status is unpaid guest.<br />
7. What happens <strong>to</strong> <strong>Meitner</strong> in 1912? In 1913?<br />
In 1912 she is made Max Planck’s assistant, assigned <strong>to</strong> marking his papers, <strong>and</strong> in 1913 she<br />
is finally promoted by Fischer <strong>to</strong> scientific associate, equal in status <strong>to</strong> Hahn but receiving a<br />
much smaller salary.<br />
8. What is Rutherford’s exciting discovery?<br />
Rutherford discovers that the a<strong>to</strong>m is not a shapeless globule, as was formerly thought, but<br />
has a tiny, but massive , nucleus that is positively charged surrounded by a wispy cloud <strong>of</strong><br />
negatively charged electrons.<br />
9. What is “the long awaited excuse for war”?<br />
<strong>The</strong> assassination <strong>of</strong> Archduke Ferdin<strong>and</strong> in Sarajevo by a Bosnian Serb nationalist.<br />
10. What were the international laws about the use <strong>of</strong> gas in war? What happened <strong>to</strong> Hahn’s scruples?<br />
International laws forbade the use <strong>of</strong> poisoned weapons. His mind was numbed by the<br />
senselessness <strong>of</strong> war , until he no longer had any scruples about the whole thing.<br />
11. What is <strong>Meitner</strong>’s contribution <strong>to</strong> the war effort? What are her impressions?<br />
She volunteers as an X-ray nurse- technician with the Austrian army <strong>and</strong> is quickly sent <strong>to</strong> a<br />
military hospital near the Russian front. She was amazed at how bad it was, how much<br />
suffering there was <strong>and</strong> that the best result for many would be <strong>to</strong> be crippled.<br />
12. Why did <strong>Meitner</strong> comment that Einstein was a curiosity?<br />
She thought his comments were naïve <strong>and</strong> that he was peculiar in his political views <strong>and</strong> she<br />
found that an educated person who never picked up a newspaper in those times <strong>to</strong> be a<br />
curiosity.<br />
