Closing Thoughts

TL;DR

  • In middle school, most of us are told we can't see a single atom with an optical microscope
  • An associate professor from the University of Otoga in New Zeland, Dr. Mikkel Andersen, leads a research group that did just that
  • Using Laser cooling they can slow the atom down
  • By controlling the amount of energy coming from a laser beam, they can break a group of atoms apart until there is one left
  • Using a deep space telescope lens, they can detect the little number of photons coming off of the single atom
  • Further research the group has achieved involves combining two and even three atoms together with full control
  • The process could be used in the future to create atomically precise products but right now, the cost and fragility of the systems make this a goal for the distant future.
