A Moment in Boston History Boston‚ Bloody‚ Boston is a documentary that depicts actual events that happened in the year 1765. The history of when and whom the key players leading up to the Revolutionary War in Boston is the focus on this mini-series. As historians can focus on the true story of what happen in Boston‚ there is often times some misconceptions of what we can perceive as truth. Many documents and photographs were all truth telling to make this documentary as true as possible. Interviewing

Liquid Film Motors [pic] Fiona McLaughlin Zoe Cheng Loreto College Coleraine Comments Abstract We have carried out an experimental and theoretical study of liquid film motors. This phenomenon was first reported in 2009. Two papers have been published on arXiv.com‚ the first describing the phenomenon (Shiryaeva et al)‚ the second offering a theoretical model for the observations (Amjadi et al). The

ello Doc Al and others. I am progressing along with my on-line basic physics course. I completed a new module and have some assessment questions to answer. Please review and let me know the ones that are correct. Those that are wrong just a little clue as to where my thinking process went a stray. I will add my thought process to the ones that I missed telling how I came up with the answer that I did. Thanks for taking the time to assist me on some basic questions. 1.

any orientation. Although this orientation does not remain fixed‚ it changes in response to an external torque much less and in a different direction than it would without the large angular momentum associated with the disk’s high rate of spin and moment of inertia. The device’s orientation remains nearly fixed‚ regardless of the mounting platform’s motion‚ because mounting the device in a gimbal will minimizes the external torque.

embarrassing moment in our lives. Like the time someone tripped in front of everyone‚ spilt a drink on themselves‚ called someone the wrong name‚ and sang the wrong lyric to a song. In these situations‚ do we end up dwelling on that moment or do we make the best of it and laugh in the end? For me‚ I laugh. Even though at the time we may not think that an embarrassing moment is funny‚ later on down the road we may turn back and see how precious that memory was. My most embarrassing moment focuses on

Life Changing Moment Ever since I can remember I spent almost ever y day at my Grandparents house. They live right down the road from my family and me‚ and that is how they got the title “Grandma and Grandpa down the road”. They lived in a small house three bedrooms‚ one bathroom‚ and a small living room with a fire place that can worm the coldest heart. And in their back yard stood a shed filled with old farm equipment and stray cats with their kittens that I would try to catch every day. They
