PESMC Seeks Volunteers for Mercer Region Math Counts

Published January 16, 2020

This Year’s Regional MathCounts Competition is scheduled for Saturday, February 1st with a snow date of Saturday Feb. 8th  at Mercer County Community College in West Windsor Twp.

MathCounts is a math competition for 6th, 7th and 8th grade students sponsored by the National Society of Professional Engineers.  Winners in our region have typically placed at or near the top in the State competition and have continued on to the National Competition.  In 2006 the National MathCounts Champion, Daesun Yim, from Community Middle School in West Windsor, participated in our Regional Competition.  This year’s National competition is going to be held in Orlando, FL.

We need volunteers to proctor, score and help administer the competition.  The competition from set-up to final awards is from about 8 AM to about 3 PM, but you may only spend 2-3 hours in the scoring room or proctoring the morning testing session if you like.

Even though this Regional Competition is not scheduled during the actual dates of E-Week, it is part of the PESMC’s Engineer’s Week’s activities and gives everyone in the office an easy way to get involved and participate in a positive experience for both us as engineers, and our area’s middle school students.

More info regarding the MathCounts Competition can be found here

If you are interested and available to volunteer a few hours of time well spent, please reach out to Chris Iacono at chris.iacono@wsp for more information.

Mercer County Community College (MCCC) recently constructed a $1.2 million, 3,000-square-foot advanced manufacturing lab. The laboratory features high-tech machining equipment, including CNC Machines, mills, lathes, saws, grinders and presses as well as a classroom with workbenches and computers. Additionally there is a room devoted to 3D printers. MCCC currently offers both certificate and associate degree programs in advanced manufacturing technology. Students are able to go on to earn a bachelor’s degree from New Jersey Institute of Technology. The Advanced Manufacturing Technology program is designed to prepare students for the modern manufacturing environment. The program prepares students for positions in shops and manufacturing facilities. Students will be eligible for NIMS certification. Typical tasks include setting up and operating equipment such as engine or turret lathes, milling machines, and power presses. More advanced tasks involve operating computer- controlled manufacturing equipment (CNC) and programmable logic controllers (PLCs) or robots for assembly lines.  The lab, which was funded in part by the Building Our Future Bond Act, is the first major construction project on the college’s West Windsor campus since the welcome center was built in 2009.

Built in 1792, the Stone Arch Bridge over Stony Brook in Princeton is the oldest state-owned bridge in New Jersey still in use. The triple-arch stone bridge was built by local masons and caries vehicular traffic for Route 206 in Mercer County. A partial collapse of the parapet and spandrel wall of the Stone Arch Bridge forced the bridge and section of roadway to be closed on February 22, 2016. Emergency repairs were performed to allow for the continued use of the bridge while advancing needed coordination to identify the most feasible and practical methods for a much-needed and more thorough repair, while preserving the historic features of the bridge and the Historic District within which the bridge lies.
