myraid of bridge types

I would certianly agree that many bridges are interesting and beautiful.  I am often more impressed by design of practical things than of objects that are formally called art.  If you ever get a chance to look at an integrated circuit under an electron microsocpe you find something incredibly beautiful in its own way. 

As for bridges, I had an opportunity to walk inside of post tensioned cast-in-place concrete box girder structure just before it was completed.  The spans started from both sides of the river and met in the middle.  Getting that right was quite a feat.  We were about 200 feet above the river with this ten foot gap in front of us.  I was a little scary, but wonderful.  Indisde the span were the cables and other structure of the bridge.  While few would ever see it, it was intersting in its own way.  I'm glad I got a chance to see it.

I have been fascinated/terrified by bridges since I was young. My fascination started in high school when we were tasked in a physics class to build a bridge out of dry spaghetti and glue. The test was to see how many bricks our teacher could hang from the bridge before it cracked. I can't remember how many bricks my bridge held, but I do remember drawing designs and working with my dad to test out different ideas.

My love for bridges was indeed renewed the first time I visited San Francisco. Walking along the Golden Gate Bridge was exhilarating.

Of course, there are the awful stories about bridges failing -- Minnesota bridge collapse, the Boston (where I'm from) nightmare called the Big Dig. For this reason, I also hold my breath when driving across these spans.

Bridges are indeed a great example of great engineering combined with great design. I live in the Boston area and was witness to the whole development effort around the Zakim Bridge, which indeed permanantly altered the Boston skyline. It's always amazed me how engineers are not only able to come up with these unique architectural designs, but more critically, buy off the engineering feat to actually bring them to life.

The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
Despite the astronomical benefits offered by 3D modeling, it is quite surprising that nearly 75% of the manufacturing industries still perform design operations using 2D CAD systems. What is the reason that keeps companies hesitant from adopting 3D technology?
Energy harvesting in particular seems to be moving at an accelerating pace. We now seem to be at a point where it is possible to run low-power systems primarily from energy harvesting sources. This is a big shift from even just a couple of years ago. Three key trends seem to have accelerated this dramatic shift.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
