Before this, I would like to return to the story of Leeuwenhoek whose work laid the foundation for both microscopy and microbiology. However, it is often unclear how this coupling specifies the complex emergent dynamics that define such behaviors. Students must be nominated by a teacher or other adult who has served in a formal or informal mentorship capacity.
