My classmate Abdulrahman and I were given robot parts to build according to the instruction in one class, and we had to make it moving backwards and forwards . In the next class, we continued working on the robot we built to perform certain tasks.  Lecture was given on distance, velocity, and acceleration. One of the most important tasks was to connect the robot to the PC and program it in order for it to perform. We measured the circumference of the wheel, which was 0.1760m, to determine how far it can travel in one complete rotation of the turn.  By programing the robot different numbers of power due a constant time, the results of rotation, number of wheel turns, velocity, and distance will change directly proportionally. The following table illustrates the relationship previously described.

Time= 1s

Circumference of the wheel= Pi* wheel diameter = 0.1760m

With time being constant at 1 second, velocity and distance are always equal according to the famous formula: velocity= distance/time.

Conclusion, although it was more of entertaining activity, it was very informative and encouraging in way that connects my preference in doing physical work with physics.

On Thursday 19th, the class went on a tour to the Sawyer library. We were introduced to several services at the library such as the circulation and reserve desk and the reference desk, which are very essential for a library to have. The three-floor Sawyer library has numerous study group rooms and the students are provided with computers and printers.

Circulation and reserve desk provides students the opportunity to borrow text books for 20 minutes at a time. Reference books can be borrowed and taken out of the library for a period of time. This desk is a huge source for students to get their questions answered regarding their study and search. Our tour guide from the reference desk demonstrated all the possible ways to search using the computers in the library. By entering a title or keyword of a book, report, or journals, we are able to find an enormous amount of information from the list of sources the university supplied. For instance, Library catalog option allows students to view all of Suffolk University library on the screen. Databases by subject is a gate to find any subjects or articles , which the library provides associated with EBSCO Host.

Overall, regardless of all the services provided, the library is environmentally prepared. Personally, I’m more productive at the library than at home considering the study.

Was Hurricane Sandy made worse by global warming? It is more controversial then we’d think. Sure, the Hurricane was one of the worst in the 20th century. When we try to determine whether or not the Hurricane Sandy was intensified by global warming, we have to analyze and understand the how it was created. Many scientists blamed global warming and many others said the opposite.

Since the hurricane was a meeting point of tropical warm waves and cold waves, it is conceivable to say that global warming is a reason for warmer waves, which indicates the rise of the tides and the destructive energy held by them. Sea level is an important factor where it has risen in the past few years. On the other hand, some scientists have proven that global warming might alter atmospheric conditions so that future hurricanes may be pushed away from the East Coast.

From my perspective, Hurricane Sandy might’ve been affected by global warming, but we also could say that future hurricanes would be less severe by the effects of global warming.
