  2. Professor Calculus - Wikipedia

    en.wikipedia.org/wiki/Professor_Calculus

    Calculus first appeared in Red Rackham's Treasure (more specifically in the newspaper prepublication of 4–5 March 1943 [2]), and was the result of Hergé's long quest to find the archetypal mad scientist or absent-minded professor. Although Hergé had included characters with similar traits in earlier stories, Calculus developed into a much ...

  3. Absent-minded professor - Wikipedia

    en.wikipedia.org/wiki/Absent-minded_professor

    "Doc" Emmett Brown from Back to the Future is an example of an absent-minded scientist-inventor character. He is depicted as strange, eccentric, or insane. Another example is the title character in the film The Absent-Minded Professor and its less successful film remakes, all based on the short story "A Situation of Gravity" by Samuel W. Taylor.

  4. Eccentricity (mathematics) - Wikipedia

    The conic of eccentricity 0 in this figure is an infinitesimal circle centered at the focus, and the conic of eccentricity ∞ is an infinitesimally separated pair of lines. A circle of finite radius has an infinitely distant directrix, while a pair of lines of finite separation have an infinitely distant focus.

    Kepler's solution is to use =, x as seen from the centre, the eccentric anomaly as an intermediate variable, and first compute E as a function of M by solving Kepler's equation below, and then compute the true anomaly θ from the eccentric anomaly E. Here are the details.

  8. Marshall Hall (mathematician) - Wikipedia

    He proposed Hall's conjecture on the differences between perfect squares and perfect cubes, which remains an open problem as of 2015. Hall's work [6] on continued fractions showed that the Lagrange spectrum includes all numbers greater than 6. This interval is known as Hall's Ray. The lower limit of Hall's ray was established by Freiman in 1975.
