Image of cultured hippocampal neurons [Source]. The hippocampus, if you remember, is the part of the brain responsible for encoding memories. I think this image is interesting because you can see how many protrusions there are from each neuron (dendrites and axons).
The search for meaning is not limited to science: it is constant and continuous—all of us engage in it during all our waking hours the search continues even in our dreams. There are many ways of finding meaning, and there are no absolute boundaries separating them. One can find meaning in poetry as well as in science in the contemplations of a flower as well as in the grasp of an equation. We can be filled with wonder as we stand under the majestic dome of the night sky and see the myriad lights that twinkle and shine in its seemingly infinite depths. We can also be filled with awe as we behold the meaning of the formula that define the propagation of light in space, the formation of galaxies, the synthesis of chemical elements, and the relation of energy, mass and velocity in the physical universe. The mystical perception of oneness and the religious intuition of a Divine intelligence are as much a construction of meaning as the postulation of the universal law of gravitation.
