Welcome to the 18th 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.
As we usually do, we have sifted through the stemng tag and even though there were several good posts to choose from, below are the posts that stood out for week #14.
In the world of electronic devices, there are mostly the talks of Read Only Memory(ROM) and Random Access Memory (RAM). It is a subject we might already have an idea of what the terms stand for. But for more in-depth knowledge, please check the blog post by

The 
@mrbreeziewrites writes on the maintenance aspect that a production engineer will have to carry out to ensure machines in his care are in optimum working condition. The writer went on to detail the importance and types of maintenance, plus the failure patterns. It is a good read for everyone that may want to squeeze more life out of their equipment.
On this day, 
@hboi took us down the road of power system engineering with emphasis on transmission lines. If you are into power system engineering, the post is tailor-made for you. The different types of transmission line modes which include the balanced, unbalanced, etc. were featured in the article.
The 
@samminator took us on a rollercoaster ride of the world of inventions and science. The blog started off with how we can feel virtual objects, to the bizarre but true story of the blue-coloured people. Other goodies may take the whole digest. So head over and check the blog URL above.
Some people are apprehensive about the role robots will play in the future. There is the fear that they will render a lot of people jobless via automation, with robots taking over the available jobs. The 
@funmiakinpelu looks at the possible bright side of the robots as companions. It is a post worth reading. Do not just take our words for it, click the link and confirm for yourselves.
The post by 
@addempsea takes a look at the common naturally occurring metal-the iron. The article looks at the extraction, the forms, usage, and its alloys.
The last post of the week was one done by 
@prettyprecy. It was on how to make rainfall through the use of cloud seeding procedures. If you will like to know what that means, then the post will be beneficial for you.
