Slideshow: What I Learned in Engineering School

A skyscraper is a vertically cantilevered beam. The primary structural design consdieration is not resistance to vertical (gravity) loads, but resistance to lateral loads from wind and earthquakes. For this reason, tall structures function and are designed conceptually as large beams cantilevered from the ground.(Illustration source: Earthquake Buddy)

Agree, William K. The same should hold true for all dissatisfied users of "Big Oil."

I would suggest that those who hate cars should be forbidden to use them, which certainly seems fair to me. And it may educate a few folks as well.

Don't forget to add the "Stop for pedestrians" zones in the middle of most blocks on college campuses to the inefficient stop conversation.  I wonder how much greenhouse gasses are added to the atmosphere because of these feel good zones.

The whole problem is that if the politicians admit that it was a mistake, that they will be expected to correct the problem. So nobody in Michigan politics admits to ever making a mistake. That is probably a political thing, I suppose.

Nobody will acknowledge that the four way stops reduce fuel economy, increase pollution, and make the intersections less safe. So that problem does not go away either.

What could it be then?

It couldn't be political.

We have lots and lots of four way stops, and a few 5-way stops also. In addition we have the "Michigan Flip" arrangement for making left turns on almost all divided roadways, residential or main. And no oil production anyplace to be seen, although there are some old wells that are not working. So please don't blame the oil companies for municiple government stupidity. They are the same fools who claim that stop signs at every single corner prevents speeding.

William,

Come to Florida from May to Sept. where there's no snowbirds.

I think the preponderance of 4 way stops can be explained by the fact that they are the most inefficient intersection. 

From my experience, they are usually used in oil producing states. 

Need I say more?

The problem with drivers in Michigan is that if you can pay the $16 you get a license, if you are over 21 years old. If you fail the written test they tell you the right answers and then give you the license. It seems that driving is regarded as a right, not an earned privaledge. And so we have a whole bunch of people who have no clue as to how to merge and are unable to focus their attention in order to drive safely. In addition they simply don't understand anything about inertia or friction, and how that relates to stopping a vehicle.

In addition we have a good number of folks with the classic "17 second reaction time" symdrome, and they often make for some real excitement on our roadways. And those snow-bird-brains are one more reason why I would nevber ever visit Florida again.

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?

In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
