Engineering Technology East and West: Riding on a Bullet (Train) in China

At this moment I am on a bullet (i.e., high speed) train from Xi'an to Beijing in China. It is a 4.5 hour trip at speeds of over 325 km/hr (200 mph). So cool! I am very fortunate. Since founding AFT 25 years ago, I have been able to travel the world and visit 30 countries. Along the way, I have made many international friends and have met many engi...

Fluid Mechanics 101 – The Class That Changed My Life

I was 20 years old and 18 months away from finishing my formal education. Forever. I was well on my way to being a…structural engineer. Wait, that must be a typo. Structural? Really? Where did the fluids come in? I really liked structural mechanics and that was where I was focused for the first 2.5 years of my mechanical engineering studies. My cla...
