Hamilton had discovered vector division. Q=A/B (Q is quaternion. A and B are two vectors.) Q.w = A dot B / B^2 ----- (3) Q.v = AXB / B^2 ----- (4) Equation (3) is applied to divide a length vector(L) by a velocity(V). L/V = (L dot V) / V^2 or L/V = L^2 / (L dot V) Also we can calculate pressure(p), p = F/A = (F dot A)/ A^2 = |F| cos(theta) / |A| where F is force, and A is area. Equation (4) is applied to divide an area vector(A) by a length vector(L). A/L = AXL / L^2 or A/L = A^2 / AXL You may find the above applications in this thread.

Dear Pmb, Do you have any questions?

SRians always describe themself a superior understanding of Einstein's four dimensional spacetime, but they are ill-trained in three dimensional vector algebra. What a bloody joke.
