A review of the history and early attempts at a comprehensive understanding of the weirdness of quantum mechanics is attempted. The emphasis is on the concept of entanglement and its intricacies. The weirdness associated with this concept is exemplified by citing the old Schr6dinger＇s cat hypothetical experiment. The modern cousins [1] of the Schr6dinger cat and their technological applications are also described. This includes recent applications such as ＂quantum teleportation＂ and a very recent one （27 August, 2014） which is called ＂telepathic quantum imaging＂, in which an object was imaged by photons which have not interacted with it, utilizing the information from their sister entangled photons generated in a nonlinear optics arrangement [2]. The modern view of how entanglement can arise as a result ofa fractal space-time geometrical setting is also briefly described, and the reciprocal very recent point of view that fractal-space time itself can be an emergent phenomena arising from the interplay of entanglement and information [3] is cited. The overall theme of the lecture is to emphasize some known, but sometimes forgotten, understanding of how fundamental theories in physics advanced by curiosity to understand nature, which may seem strange and weird in their beginnings, may turn out to have very important technological impact in our daily lives, but this may take relatively long times. This should be taken to represent a strong call to give this aspect the necessary concern in our teaching curricula and research projects, balancing the current trend calling mainly for emphasis on applied research.
