Patents and iventions of nature I.

We can meet the physical patterns not only in
work of many apparatus, machines and technical
devices but also in phenomenon of wild nature.A
lot of things created by nature are admired by
confessors of technique. A lot of things became
an inspiration for a number of technical
inventions. We offer you in the form of a
presentation a how of the first part of our
physiclal research in the world of alive nature
which we make in realisation of ESF project in
our school for SPP. Gradually we will present
more shows by this form. In the end of the
project we are going to prepare a compact
material.

• Beatle 3 4 cm
• It has got 2 yellow shining pimples on the sides
  of the nuchal clypeus

  shining mass luciferin, the second ferment
  enables rich oxydation during which energy-light
  is emited
