b'Why aren\\u2019t there ant sized elephants? Or, why aren\\u2019t there elephant sized ants? What is small, large or infinite? Are there theoretical limits to size for living & physical bodies? Was the Universe infinite in size even at Big Bang, & how? Is there a center of the Universe? Are there different kinds of infinity? Do different infinities have different cardinalities? What is countably or uncountably infinite? Can there be an infinity \\u2018smaller\\u2019 than Aleph-naught? How is infinitely small (infinitesimal) different from infinitely large? Would the smallest interesting living bodies be about 3,000 Angstroms in size, & why is this dependent on the size of DNA? Is there a reason why whales are larger than elephants? What is the reciprocal of infinity? How can point-like elementary particles be massy? How large is the (yet unknown) elementary particle comprising dark matter likely to be? For natural evolution, over very long time scales, does it pay to be small? Are we equally incapable of seeing the nothingness from which we emerge and the infinity by which we are engulfed? SynTalk thinks about these & more questions using concepts from evolutionary & developmental biology (Prof. Vidyanand Nanjundiah, Center for Genetic Studies, Bangalore), mathematics (Prof. Sujatha Ramdorai, University of British Columbia, Vancouver, Canada), & cosmology and particle physics (Prof. Raghavan Rangarajan, PRL, Ahmedabad).
