    Does Torque Transform Like a Vector in Different Coordinate Systems?

    Problem: Find the transformation matrix between the coordinate systems C and C′ when C′ is obtained i) by reflecting C in the plane x2 = 0 ii) by rotating C through a right angle about the axis OB, where B is the point with coordinates (2, 2, 1). In each case, find the new coordinates of...

    Maskelyne's Schiehallion Experiment

    Problem: The first estimate of Newton’s constant G was made by Maskelyne in 1774 by measuring the angle between the directions of the apparent plumb-line vertical at points on opposite sides of the Scottish mountain Schiehallion (height 1081 m, chosen for its regular conical shape). Find a...
