Welcome to the 9th 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 can be found here while information of what it means to be part of steemSTEM can be found here as well.
As we normally do, we have rummaged through the stemng tag and even though there were several good posts to choose from, below are the posts that stood out for week #9.
Basic understanding of science taught us that when friction occurs between two surfaces, heat is generated as a result. Also, the efficiency of any machine can never be 100% due to friction. As useful as this frictional force is, it is less desirable in industrial machines. Scientists try to limit this force in machines by the use of bearings, of which journal bearing is one. How does it work actually? Educate yourself by clicking on 
It is quite amazing what the development of engines has made mankind to achieve. From motor vehicle engines, ship engines, train engines, aircraft engines to the not so popular engines. As a life scientists, I have not really sat down to fathom the principles upon which engines work. Thanks to steemit and to

There is no denying the fact that energy is important to life. Life cannot exist without energy. In this post, 
This post reminds me of my high school geography. However, it has so much more than high school geography. The story of the burial of the Egyptian Pharaoh makes this post very interesting to read. Who could have thought that what we nowadays understand as simple natural phenomenon was once a source of serious commotion and confusion. What do you all think I'm talking about? The eclipse of course! How does it happen and what are the explanations behind it? 
The development of science is one of the best things to have happened to mankind. If I get involved in a discussion and someone tells me that fungi can help in criminal investigations, I would have said no. However, reading through this post by
