Triangle trigonometry essentials
Law of Sines:
a / sin α = b / sin β = c / sin γ
Law of Cosines:
c² = a² + b² − 2ab cos γ
Law of Tangents:
(a + b) / (a − b) = tan((α + β)/2) / tan((α − β)/2)
Plus half-angle identities and the area formula sin α = (2 / bc) √[s(s−a)(s−b)(s−c)] where s = (a + b + c)/2.
These are standard tools in surveying, navigation, astronomy, engineering, and computer graphics.
The speed of light was measured before electricity was understood – Ole Rømer in 1676 estimated it by studying delays in Jupiter’s moon eclipses, long before anyone knew what an electron was.
Lise Meitner, a key figure in the discovery of nuclear fission, was nominated for the Nobel Prize 49 times - 19 for Chemistry and 30 for Physics - but never won.
