The Future of Engineering - Part 1

May and June are the time for graduations in the USA. My third son graduated from high school this month and will be pursuing a major in Aerospace Engineering. My oldest son is finishing his third year in Mining Engineering and my second son has started into a Mechanical Engineering major. Engineering education and the future of engineering is a frequent discussion topic around our home. So what is the future of engineering? Well, it is safe to say that a knowledge-based society like today's society will always need engineers. From that point of view the future of engineering is secure. However, more troubling to many engineers...

Where Did the Name "Arrow" Come From?

A frequently asked question at our training seminars - usually during a break or over lunch - is how we came up with the name "Arrow". More completely, the product is named AFT Arrow ™ and it is considered by many as the world's leading compressible pipe flow modeling software product. There is a similar story behind the naming of AFT Fathom ™ and I told that story several months ago in my post entitled Where did the Name Fathom Come From? The story behind the  Arrow name is rooted in the beginnings of Applied Flow Technology as a company. So let's...

May the Force Be With You: Evaluating Unbalanced Forces Caused by Waterhammer

A common task among pipe stress engineers is to evaluate loads on pipe systems caused by waterhammer. Since AFT Impulse 4.0 was released our users have had the ability to calculate waterhammer-induced unbalanced forces for use in any pipe stress analysis application. In addition, our users can create specially formatted transfer files for direct use in CAESAR II and TRIFLEX . However, the process of calculating such forces in AFT Impulse and then applying them in pipe stress software is not as straightforward as it sounds. Our customers have asked for assistance in this process. I have teamed with Jim Wilcox of...

My 50th Anniversary Visit to the Site of John Glenn’s First American Flight Into Space

Many of you probably saw in the news that today, Monday, February 20th, is the 50 th anniversary of John Glenn’s flight into space. The flight was aboard a Mercury-Atlas rocket dubbed Friendship 7. This historic event was a significant step on the way to the Apollo missions to the moon. By good fortune the NASA contractors at Kennedy Space Center had scheduled an AFT training class last week, and I traveled to Florida to teach the class. I took some time to tour the Space Center and Cape Canaveral one evening and was able to visit Complex 14 where the launch took place....

Why I Like Bill Gates More Than Steve Jobs

I have an iPod - to which I am very attached. I have had my iPod Nano for a couple years now. All of my kids and my wife have iPods. I hike frequently in the Colorado Mountains near where I live and I can’t do it without my iPod. I can’t work out at the gym without my iPod. I can’t drive my car without my iPod. I have an iPhone – to which I am very attached. I have had my iPhone for about 6 months now. It goes with me everywhere and – along with AT&T – was...

It’s the Economy, Stupid. Or Is It?

A few months ago I attended a CEO forum in Colorado where a big topic on the minds of the 1000 CEOs in attendance was the state and direction of the US and global economy. The keynote speaker Brian Beaulieu began his presentation with this assessment of the economy from TIME magazine: The U.S. economy remains almost comatose. The current slump already ranks as the longest period of sustained weakness since the Great Depression. Once-in-a-lifetime dislocations will take years to work out.  Among them: the job drought, the debt hangover, the defense-industry contraction, the banking collapse, the real estate depression, the health-care...

Thankful for the Opportunity to Shape a Changing World

Wherever I go I see change. China is undergoing massive change in a relatively short period of time which has impacted Western nations both positively and negatively – as well as the rest of the world. China’s growth in manufacturing is impacting Australia in a huge way and driving much of the Australian economy through accessing its abundant natural resources. As we look back on the American Thanksgiving holiday I am currently on a lengthy visit to Australia and Asia training customers in the East and meeting new prospects. And seeing the changes first hand. My family is along with me and we celebrated...
