Welcome to a new episode in the stemng digest series where we bring to you some of the best posts under the #stemng tag in the past week. Let me start with an apology for the little delay in this week's episode, it was due to some real life circumstances.
As a reminder, stemng is a sub-community of steemSTEM, a community-driven project which seeks to promote well-written and informative Science, Technology, Engineering and Mathematics posts by Nigerians on Steemit. The project involves submitting quality STEM-related posts to the steemSTEM management for upvoting and resteeming where applicable.
More information about stemng activities can be found here, while information of what it means to be part of steemSTEM can be found here as well.
The management has traveled far and wide the corners of #stemng tag and selected the posts they think is the best for each day of this last week. Relax and enjoy as we take you through the best posts of the last seven days.
Apart from the rewards and meeting awesome people from all over the world, learning new things is one of the best attributes of steemit. Who could have thought that electricity could be generated by movement of bodies on surfaces? Well, I am as ignorant as some of the readers. Piezoelectric crystals has been demonstrated to be able to generate electricity by installation of piezoelectric transducer on moving surfaces. You all can read more on 
Perhaps we will get to a point where artificial intelligence will take over everything. I have always known dolphins to be awesome animals. Not talking about steemit dophins here :). Here in this post,

There is no doubt that only a small portion of the radiations from the sun reaches the earth. This means that a lot of absorption, reflections or probably re-absorption must have happened along the way via the ozone layer, the clouds and perhaps the atmosphere. How exactly do all these happen? What does the ozone layer looks like and how is the human activities affecting it? Hurry over to 
A really beautiful piece of work from 
....and finally;
Communication is an essential part of existence. Even though there are wide varieties of communication between human to human, human to animals, human to machines and vice versa, there is no doubt that data is becoming increasingly crucial in every form of communication. Exactly how are data used to communicate? 
The post for each day was selected based on consensus between the stemng management, in persons of
