With DTC, Perseverance Can Pay Off!
While there are plenty of people who pass the PE Exam on the first try, there are quite a few who don’t. We have lots of folks who come to DTC after trying to study on their own or taking review courses from other sources, and we have helped many of them pass on their […]
International Women In Engineering Day
Hedy Lamarr is often remembered for her roles in classic Hollywood films. But did you know – she was a brilliant innovator, who leveraged her knowledge of radio systems to devise a frequency-hopping communication system that enhances the reliability, security, and efficiency of wireless communication? It went on to be a crucial foundation for modern […]
Another “Units” Debate
As those who have been in one of my classes would agree, if I wasn’t Dr. Tom I’d be Dr. Units. So a recent article in the Washington Examiner, republished in an ASME SmartBrief, caught my eye. Apparently, in 1975, some 50 years ago, President Gerald Ford approved an experimental project where Interstate 19 from […]
A Cool New Way to Make Hydrogen Fuel a Reality
Hydrogen has been proposed as a way to remove our dependence on fossil fuels. Although generating hydrogen is energy intensive, it represents an effective fuel that can supplement or replace fossil fuels in applications like automobiles and combustion devices. One of the major challenges with hydrogen is storage because it must be either highly compressed […]

Artificial Intelligence’s Nuclear Option
Artificial Intelligence (AI) has become a part of our daily lives, helping us analyze data, keep our schedules, and even writing term papers. But this computing power requires a tremendous amount of electrical power, which utilities are struggling to provide. Microsoft has decided to invoke the “nuclear option” and reactivate Unit 1 at the Three […]
The “Spruce Goose” (my kind of story)
With my BS being in Aerospace Engineering, it is very hard for me not to be attracted to great aviation stories, and the story of the Spruce Goose is one of those stories. The recent ASME SmartBrief article provides some very startling specifications associated with the Spruce Goose, the largest seaplane ever built. Katherine Huit, […]
“Diminishing” Returns for Lighting Energy Efficiency
Lighting energy efficiency has dramatically increased since the days of Edison’s light bulb. In our office and retail spaces we’ve seen large improvements in fluorescent style lighting. From 180 Watt four lamp T12 fixtures in the 1980’s, to 110 Watt T8 fixtures in the 1990’s, and now 36 Watt LED fixtures with just two lamps […]
MECHANICAL PE EXAM TIP – Units, Units Units!!!
If I wasn’t Dr. Tom, I’d be Dr. Units. I cannot tell you how many times units are the reason someone gets the wrong answer to a problem. It might be as simple as inches needed to be converted to feet, or the other way around. Or, it is a combination of units like gallons per minute […]
The Dr. Tom Method – The Perfect System to Pass the PE Exam
At Dr. Tom’s Classroom, we’ve worked hard to create the perfect system to help Mechanical engineers pass the PE Exam and become Professional Engineers. We even developed and launched a whole new Dr. Tom Method specifically targeted to the CBT exam format, and it’s been a huge success. With PE Exam Review courses for all […]
