Dr. Khristo Boyadzhiev publishes paper in the "International Journal of Mathematical Education in Science and Technology"
Dr. Khristo Boyadzhiev, professor of mathematics, is author of a paper published in the "International Journal of Mathematical Education in Science and Technology," Vol. 41., Issue 5, pages 667-672.
Titled “Calculus, radio dials and the straight-line frequency variable capacitor”, the paper seeks to explain why radio dials are so confusing. In the abstract, Boyadzhiev says, “Most often radio dials of analogue radios are not uniformly graded; the frequencies are cramped on the left side or on the right side. This makes tuning more difficult. Why are dials made this way? We shall see here that simple calculus can help understand this problem and solve it.”
