Welcome to the 27th episode of the #stemng digest series where we bring to you some of the best posts under the #stemng tag in the past week.
For those that do not know yet, 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 are found here, while details of what it means to be part of steemSTEM can be found here, as well.
