In Remembrance of a True Hero
“There is but one Earth, tiny and fragile, and one must get 100,000 miles away to appreciate fully one’s good fortune in living on it.” – Michael Collins, NASA astronaut, command module pilot for the Apollo 11 mission to the moon. What struck me deeply about this particular quote is that Michael Collins died a […]
Discarded Plastics Get New Biodegradable Life
New research at the Ames Laboratory’s Institute for Cooperative Upcycling of Plastics (iCOUP) recently discovered a chemical process that transforms plastic trash into biodegradable detergents and surfactants. This new process will help make plastic use more sustainable. Researchers worked with plastics called “polyolefins,” which represent more than half of all discarded plastics, from food packaging to […]
COVID-19 Impact on Construction
Research from the University of Maryland shows the effects of COVID19 related construction procurement and worker absenteeism. The author also raises interesting questions about the supply chain and preparation effects of future decisions related to resilience. For instance, will construction and engineering firms react more quickly to future indications of disruptions by pre-ordering and strategically planning for possible […]
FEATURED TESTIMONIAL – “Absolutely Outstanding”
“When I searched the internet for PE review courses, I came across Dr. Tom’s sample video lessons and videos describing his approach for taking the PE exam. After viewing these videos, I quickly realized his course was for me, and I did not consider any other review courses after that. What impressed me most from […]
Clean Energy Equipment Avoiding the Landfill
In the next five years, Ireland will decommission more than 11,000 tons of wind turbine blades. It’s a bit counterproductive for something that produces clean energy to end up in the landfill, but at 40 feet long each, the question was: for what else could they be used? Civil engineers at the University College Cork are […]
The Yo-Yo Class at MIT
When I was in grammar school, yo-yo’s were extremely popular. Wooden ones of the previous generation had been replaced by psychedelic plastic models in all the colors of the rainbow.We even took them to school, and when the teacher was not watching, we would spin our favorite yo-yo right at our desk, careful to not […]
FEATURED TESTIMONIAL – Worth Every Penny!
“I just received notification that I passed! I kept on pace with the 20 week program. Frankly, I enjoyed doing this studying because it was a great opportunity for me to review important mechanical engineering concepts. The course was worth every penny! Thank you for putting together such a comprehensive set of information! I would not have passed […]
FAQ – How To Prevent Cracks in Concrete?
I often get asked about why concrete cracks and how to prevent cracks in concrete construction. Generally speaking, concrete is going to do two things: 1) get very hard and 2) crack. Installation of control joints provides a location for the concrete to crack, thus “controlling” where the concrete cracks. Constructed joints are much more aesthetically pleasing than a […]
