Description of the task. In order to support the Global Education Initiative, we are starting a project in which every inhabitant of the Earth able by his/her personal life story to illustrate certain scientific knowledge accumulated by humanity and to share them with others, can write the corresponding chapter for OmniBook textbook, which will contain the knowledge backed up by the impressive life experience of the inhabitants of the Earth. We encourage all who have something to write about in the OmniBook, to do so by either publishing their chapters on social medias FaceBook, Instagram or LinkedIn with the hashtag #learnedandshare and/or by sending an e-mail to gedi@omnigrade.com.
