The paper reviews two major works focused on supersymmetry and string theory, highlighting their pedagogical approach and contributions to the understanding of modern physics. The review also touches upon the historical significance of Einstein's contributions, particularly in relation to atomic energy.

Attempts to understand the strong interactions gave birth to string theory. Empirical evidence for string-like structure of hadrons comes from arranging mesons and baryons unto approximately linear Regge trajectories.

Isaacson's biographical analysis of Einstein's life reflects the nature of personal achievement in terms of the importance of inquisitiveness and the willingness to experiment.

Veneziano found the first and very simple expression for a manifestly dual 4-point amplitude. This are some notes of introduction on string theories. This notes include -Classical Strings Why string theory? We construct a locally supersymmetric four-fermion effective lagrangian description of the strong binding effects responsible for the formation of a gaugino condensate, extending the analysis to include the multiple moduli of orbifold compactification.

Using this to estimate the binding we find that supersymmetry is broken and a phenomenologically realistic value for the gravitino mass and gauge coupling constant at the unification scale with only one gaugino condensate may be obtained.

The definitive, internationally bestselling biography of Albert Einstein.

The main source for supersymmetry breaking is the VEV of the auxiliary field of the dilaton h s i. By studying the scalar potential we find either that the vacuum expectation values of the moduli have a common value related to the vacuum expectation value of the dilaton or that they take the values of the dual invariant points.

A squeezed orbifold can thus naturally be obtained, allowing for the possibility of minimal string unification. We include chiral matter fields and derive the scalar potential up to one-loop level. The one-loop potential is responsible for stabilising the scalar potential for vanishing vacuum expectation values of the chiral matter fields.
