The string uncertainty relations follow from the new relativity principle

Stringy corrections to the ordinary Heisenberg uncertainty relation shave b een known for some time. However, a proper understanding of the underlying new physical principle modifying the ordinary Heisenberg uncertainty relati ons has not yet emerged. The author has recently proposed a new scale relat ivity theor as a physical foundation of string and M theories. In this work the stringy uncertainty relations, and corrections thereof, are rigorously derived from this new relativity principle without any ad-hoc assumptions. The precise connection between the Regge trajectory behavior of the string spectrum and the area quantization is also established.
