Gender Differences Create Expensive Overcooling in Offices

A Nature.com scientific report provides additional confirmation of something most of us that work in offices or who design office buildings already know – women are always cold and men always hot in the office. The authors analyzed over 38,000 responses from a Center for the Built Environment survey performed by the University of California, […]

FEATURED TESTIMONIAL – “I Passed, All Thanks to Your Course”

“I took the Mechanical TFS exam and found out I passed! This was all thanks to your course and following the Dr. Tom method. I did not graduate with a Mechanical Engineering degree so some of the topics (especially heat transfer and HVAC) were new to me, but your lessons were a great way to […]

Calculating for Inflation

The recent news about inflation gives us a great opportunity to talk about applying some of our engineering economics concepts and equations. From November 2020 to November 2021, the consumer price index – which is a metric that measures the cost of a variety of goods and services – rose 6.8% over that one-year time period. What would […]

Brownfields into Brightfields

I grew up watching the TV series “Sea Hunt” staring Lloyd Bridges. The lead character had been a former Navy frogman, what is now called Navy Seals. With his sophisticated scuba gear he seemed to be able to go anywhere under the water.  What I would come to learn in my fluid mechanics classes is that […]

The Mothership – Science Non-Fiction

I think the first time I heard the term “mothership” was in the sci-fi movie “Independence Day.” The term is now commonly used to reference a space ship that can deploy and recover smaller versions of itself. However, up until now this concept was only science fiction. Well, according to a recent Breaking Defense article, DARPA, […]
