You've Never Touched Anything

Electrons push back before atoms ever meet

Your hand on a table feels like solid contact. Zoom in far enough, and is anything really touching at all?

You'll find out

  • Why atoms have no hard edge
  • How hard atoms push back up close
  • What your fingertip really feels

Why it matters

Every touch, grip and footstep runs on this push, and it's why solid things don't sink into each other.
