The article “Why stars look spiky in images from the James Webb Space Telescope'' by Griggs (2022) discussed the causes of distortion in the images produced by the James Webb Space Telescope. These distortions are determined by the telescope being used, and its design and hardware. The JWST is a reflecting telescope that uses light from the universe to form images using mirrors and imaging instruments. The shape of the mirrors affects how lights can diffract around the mirror’s edge. The JWST consists of primary and secondary mirrors, where the primary hexagonal mirrors contribute to the six diffraction spikes in the produced image, and the secondary mirrors are held by three struts that are 25 feet away from the primary mirrors. These struts also contribute to the distortion due to how light diffracts off the struts. There are mainly two instruments that produce images from the telescope. The Near Infrared Camera (NIRCam) uses near infrared lights to capture the image while th...

To Professor Brad Blackstone and my fellow classmates. A warm greetings to everyone. My name is Zong Xiang and I am currently pursuing a degree in mechanical engineering at the Singapore Institute of Technology. I hope you will learn more about me both as a student and a person .  I graduated from Singapore Polytechnic with a diploma in mechanical engineering in 2020. At first I had no idea what to pursue and I was recommended by my cousins to go into mechanical engineering as they were engineers. Mechanical engineering has grown on me as it was related to my interest in Formula 1 and aviation.  One communication strength which I feel I have is the ability to communicate effectively in a team. I could communicate well in a team setting to achieve our goals for our tasks during my work in school and in National Service. One weakness I have is that I tend to not be confident when I speak during a presentation as I stutter often. Hence, one of the goals I have for this module is ...

After reading the excerpt, I do agree with how critical thinking is seen as an engine or soul of communication. Arguments in a workplace occur due to misunderstandings from one colleague to another or from a leader to his team. In my opinion, these can be avoided if they take a second to think about what they plan to say to avoid unneeded conflicts from one another as some words and tones can be easily misunderstood if they are said in a wrong way. Moreover, critical thinking and communication are the keys for me to be a future leader in a workplace. Knowing how to effectively communicate with my colleagues and teammates allows us to progress together during a project or work as you are able to provide constructive feedback and thus bring out the potential of one another to achieve the goals of the project or work on schedule. Being clear with a message in an argument or feedback helps in reducing misunderstandings with my colleague and teammates and allows us to do our work or project...
