Great lecture series! Is there a mistake at 8:20? root expression behind delta-t should always be smaller than 1 so delta-tmin should always be smaller than delta-t?
best regards from Germany

Yes, shouldn't delta-tmin always be smaller than delta-t? Is there a mistake at 8:20?

[@tasniasarah1514]

if delta t-min is always smaller than delta t ,does this mean that the principle of causality breaks down?
