1What Counts as Evidence? - Mitchell documented her comet observation carefully, kept records, and reported it through the proper channels. But when competing claims emerged, the question of who was 'first' became complicated. What does this tell you about how scientific priority is established? What information matters?
2The System That Made Everything Harder - Mitchell's achievements were real: the comet, the medal, the professorship, the students she trained. But every one of them required navigating barriers that male scientists of equal talent would not have faced. How do we separate a person's accomplishments from the conditions under which they achieved them?
3Being Paid Less for the Same Work - Mitchell discovered she was underpaid and complained. This was not a common action for women in her position. What made it possible for her to complain? What would have been different if she had not discovered the discrepancy or had chosen not to raise it?
4The Library as University - Mitchell educated herself by reading every book in the Nantucket Atheneum. She continued her observations on her own. She became one of the most skilled observers in New England before anyone outside her town knew her name. What does this tell you about what 'credentials' actually measure?
5The Gap Between Achievement and Recognition - The King of Denmark noticed Maria Mitchell's comet. Most history books do not mention her. Why do you think the gap between her achievement and her historical visibility is so large? Does it matter, and if so, to whom?

Key Takeaways
◆1. Systematic Barriers Do Not Prevent Achievement - Maria Mitchell faced every barrier that women in science faced in the 19th century, and she still made discoveries that earned international recognition. Barriers are real. They make things harder. They do not make them impossible.
◆2. Fairness Requires Advocacy - Mitchell discovered she was underpaid and complained. Her salary was raised. This required that she know the salary information, believe she had the standing to object, and take action. Not everyone in her position would have had access to all three of those things.
◆3. Credentials Do Not Measure Everything - Mitchell educated herself through reading and observation. She had no formal degree until she was hired by Vassar. Her credentials were the observations she made, the records she kept, and the discoveries she published. Understanding what credentials actually measure - and what they miss - helps us read claims about expertise more carefully.
◆4. Recognition Is Structured - Mitchell received a medal from the King of Denmark but was largely omitted from American history books. The King of Denmark had a rule about who could receive credit for discoveries. American historians had a different set of rules about who counted as a significant scientist. Neither set of rules was neutral.
◆5. The Pipeline Starts Somewhere - Mitchell's students went on to become the Harvard computers who catalogued hundreds of thousands of stars. She trained the next generation directly. That work - training the next generation - is often less celebrated than individual discovery, but it extends a person's impact across decades and institutions.
