A Brief History of Tau
1976, Tau was born in John Hopkins.
1992, the first non-invasive try, Harvard.
1992, the first formula, with four assumptions, Harvard.
1993, another non-invasive try with decent data, Mayo Clinic.
1995, a similar strategy applied to AI patients, Japan.
1995, I published a MR based formula with one assumption.
1997, the Harvard formula was validated in Cleveland.
2005, Langer presented a non-zero asymptote model.
2008, I improved my MR based formulas, without assumption.

Tau and Beyond
Tau renders us a new approach to the cardiac function assessment. Since Tau is directly related to how powerful the muscle is at the beginning of diastole, it is well accepted as the best index to describe diastolic function.

A Tale of Two Harvard Profs: Anversa Opened a Wrong Door, Thomas Closed a Right Door
When I read "The Emperor's New Clothes" as a child, I didn't take it seriously. It seemed like a funny tale, just the adults' way of fooling kids around with their wild imaginations. However, as I grew up, I realized that this story could actually happen in the adult world. It's astonishing to see how even intelligent and respectable individuals can get involved in such situations.

A Small Step in Math, A True Stride in Cardiology
With the progress of Doppler and modern computer technology, I believe that only a few RBCs’ leaking will be needed to give us a much understandable and clear regurgitation curve. Theoretically, merely a short part of the curve is enough to calculate the Tau. As long as we are allowed to choose 3 points from within the definition field, we can use the updated formulas to proceed. Let’s assume the 3 points are a (va, ta), b (vb, tb) and c (vc, tc) from left to right. The updated formulas are:
