1993, Dr Nishimura put his hand on Tau. In the Table 1 (Comparison of Catheter-Derived and Doppler-Derived Variables for 120 Beats in 15 Patients), his measurement is Tau=58ms, (v1-t3)=48ms. 15 years later, I published the Tau formula Tau=1.2(t1-t3). Here comes a miracle: 58=1.2x48. Dr Nishimura has to command the profound respect of us, how such an accurate measurement is possible! In the meantime, my formula is also validated objectively. Now this formula is integrated into Mindray’s Echo machines sold all over the world except North America. This is the Good.

1992, Dr Thomas developed a Tau formula at Harvard. 5 years later, it was “validated” by Dr Scalia and the paper was published in Circulation. The scientific discovery path is destined to be bumpy as Cicero reminds us “any man can make mistakes…”. This time the marriage of Harvard and Circulation doesn’t guarantee win-win cooperation. This method is incorrect with logic flaws. Playing with the Google Scholar, you will find nobody used this formula to calculate Tau in the whole year in 2019. This is the Bad.

I believe I found the right way to calculate Tau, please let me know if I am wrong. Researchers based on my Tau formula found it hard to get their paper published due to the Harvard method. This is the Ugly.

Only retraction of Dr Scalia's paper will set Tau free.
