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 […]
Generating Water and Cooling from Thin Air
Over the next 30 years, the greenhouse gases produced to provide air conditioning to more of the world will increase by a factor of five. Potable water will also become increasingly more difficult to find. What if these two problems could be paired together to provide a solution? Scientists are developing a new type of […]
FEATURED TESTIMONIAL – “Dr. Tom Does a Sterling Job”
“If it wasn’t for Dr Tom’s encouraging and clarifying teaching style, I doubt I’d ever have the courage take on the Thermal and Fluids Systems PE exam. In fact, Thermodynamics and Heat Transfer were the areas in which I was struggling the most in college, some twenty years ago. Dr Tom’s course made these ‘difficult’ […]
A New Way to Cool Efficiently – Electrocaloric Effect
Electrocaloric cooling is not exactly new, it has been around for a while now, but new materials make this a potential industry changing technology. Electrocaloric cooling is cooling accomplished by putting certain materials in an electric field (applying a Voltage). The materials naturally move heat energy from one side to the other. That creates a […]

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 […]
A Big Problem with a Weighty Solution
With the rise of intermittent renewable energy sources, like solar and wind, there needs to be a way to store excess energy produced and use it when it is not available. Many utilities use hydroelectric facilities where water is pumped up to an upper lake when energy is available and then back down through turbines […]
PI – Around and around we go!
Today is PI Day and if there is any number that should be celebrated it is PI. PI shows up in so many formulas and equations in math and science and engineering that it would be virtually impossible to make even a passable list. For mechanical engineers, anything rotating “around and around”, like gears, will […]
FEATURED TESTIMONIAL – “Wonderful Training for the PE Exam”
“I took my computer based exam after going through the newly developed DTC training for Mechanical CBT, and it was a huge help. And the BEST news? I passed!! The testing strategy provided by Dr. Tom and team allowed me to stay relaxed and I found myself with plenty of time after each section to […]
