In biology, for example, there has already long as it is proven:

Indeed, as you marked there are convergences where the use of genetic or other trees, that speech is extremely attractive (not least because as any other notice as the earth is round, the earth does is not the center of the universe, etc ... is considered heretical and sectarian).
This kind of convergence is found with HIV and shared by the large majority the medical world, and heretics have been and are the object of all the sarcasm of their opponents (like Dede). So it is not arguments and cons arguments but simply a principled opposition.
If this step is not crossed, everything else is discussed in a vacuum.

Same thing: what protocols? Such as AIDS, vaccines, nuclear, chemical and others?

But in principle, all options are open, therefore. it is not contradictory to say that a wall is blue if it has measurable degrees Kelvins corresponding to its color ...

I am a technician and professional training and know the possibilities and limits of devices designed and manufactured for a particular use and not beyond. So a measure is neutral, it does not take sides for or against the use made of it ... humans yes!
So on the theory of evolution, it (the performers) retains only what is going in this direction and considers that all the grains of sand of the machine are not taken into account. Now these are the grains of sand that enrayent machinery and scientific research also serves to highlight these sand grains in question. The example (a little old) coelacanth is ONE of these grains in question.
Same thing must be changed over! :D

I thought the topic dealt with the construction of a wind.

- Here, there is one who built this optimized wind turbine! Look here :

, and tell me if I'm wrong !!!

Hi,
New on the forum, I would like to know if people have managed the feat of installing a wind turbine in their garden without problem with the neighborhood. For several years, I participated in a study of implementation of a wind farm offshore and 3 years it is postponed because of hypothetical visual nuances. At almost 20 km from the coast, it is likely that we see a security light, but by day it should be neutral.
Thank you in advance for sharing
