How Alexander Fleming did or did not resemble the traditional scientific method?

Alexander Fleming's discovery of penicillin through accidental contamination diverged from the traditional scientific method, which involves formulating a hypothesis and designing experiments to test it. However, he did follow up on his observation with systematic study, isolation, and characterization of the compound, aligning his work with the scientific method overall.


Who started time zones?

Time zones were first proposed for the entire world by Canada's Sir Sandford Fleming in 1876 as an appendage to the single 24-hour clock he proposed for the entire world (located at the center of the Earth and not linked to any surface meridian). In 1879 he specified that his universal day would begin at the anti-meridian of Greenwich (now called 180°), while conceding that hourly time zones might have some limited local use. He continued to advocate his system at subsequent international conferences. In October 1884, the International Meridian Conference did not adopt his time zones because they were not within its purview. The conference did adopt a universal day of 24 hours beginning at Greenwich midnight, but specified that it "shall not interfere with the use of local or standard time where desirable".
