  Alistair Lewis, an atmospheric scientist, reported in The conversion (13 May, 2020) that connecting air pollution and coronavirus is superficial. She states that correlating the two “have often failed to take other geographically-connected factors into account”. She says that air pollution in rich countries is “usually a population-centred problem”, this close link between cities and air pollution makes it hard to identify how pollution effects the mortality of COVID-19. She then focuses on urban areas, stating that they face similar situations through the regular use of mass transit system. Air pollution data is one of the only legitimate data that is easily accessible, leading to one having the misconception that air pollution has a proportionate effect on COVID-19 while referring to the data. The writer believes that more datasets will appear in future to allow one to study the connections between air pollution and COVID-19. Until that happens, she believes that connecting the...

  Dear Prof Blackstone Subject: A Self-Introduction by Dennis   My name is Dennis, a graduate from Ngee Ann polytechnic currently holding a diploma in mechanical engineering.  During the curse of three years, I had a deeper understanding in the engineering field which increased my interest in engineering. Being an engineer often requires you to think out of the box, there is never a standard answer to a problem, different engineers can have different ideas that will lead them to the same goal. After hearing a professor telling me about Sustainable Infrastructure Engineering (Building Services) program enthusiastically, I knew this program will help me achieve my goals.   My goals for this module are to eventually be involved in building projects, to look at a complete project knowing that I am part of the reason why this project is a success.  My weakness is that I find it very hard to concentrate for long hours. Therefore, my study sessions always follow ...

 In the engineering world, we always learn that our language are in terms of SI units and numbers. While i can agree to that statement, I still can understand why Debra Kraft made his statement. We look at construction sites, a place where we will frequent from time to come, a simple "yes or no" answer could be the cause of a fatal accident. Misinterpreting the words from your higher ups could lead to a child losing her parent.   On a Global scale, where people from different countries come together to work on a project, it is very important that they fully understand the pointers that are made by each meetings.
