Exploring Microworld Similarities: Small and Large Movements Compared

Delve into the concept of similarity in the microworld, comparing slow motion of tiny objects to fast motion of larger ones. Understand Reynolds number, flow velocity, viscosity, and more in relation to microworld exploration. Explore how flows with similar Reynolds numbers share unique characteristics and how this applies to both small and large objects in different liquid environments. Take a journey through Rhodobacter, E. coli, and Howard Berg’s Laboratory to grasp the intricacies between high and low viscosity in the macroworld and microworld. Discover the fascinating comparisons between small, slow-moving entities and large bodies in very viscous liquids. Join us to witness the wonders of the microworld and unlock the secrets that lie within.

  1. Looking at the microworld with the naked eye Can the slow motion of something very tiny be similar to a quicker motion of something considerably larger? Maciej Lisicki Maria Ekiel - Jeżewska

  2. What does it mean 'similar'? Identical shape is not enough... http://www.tukan-webdesign.de/krusenstern2/Krusens%20neu%20als%20Taste%20m.Schatt400x383.jpg http://www.mmszczecin.pl/8307/2007/9/20/klub-czytelnika-zaprasza?category=interwencje

  3. Reynolds number L U ρ, μ Density and viscosity of the liquid Flow velocity Characteristic size

  4. Flow similarity principle Two flows having the same Reynolds numbers have the same character. = Low viscosity, little size, low velocities High viscosity, big size, high velocity

  5. Low viscosity + little objects Welcome to the microworld! Rhodobacter BACTERIA IN WATER E. coli Howard Berg’s Laboratory

  6. High viscosity + large objects MACROWORLD MICROWORLD Re

  7. Flows with similar Reynolds numbers are similar! Instead of looking at swimming microobjects, we can observe large bodies but in a Very Viscous Liquid!
