Engineering Advice for the Star Wars Dark Side

I’ve just seen Star Wars: The Force Awakens, and I really have some questions for the Dark Side about how they construct their bases. Look, I like science fiction and fantasy. I am willing to look over the fact that the Laws of Thermodynamics and the Laws of Physics are routinely violated. What I have trouble overlooking is that the Dark Side designs their bases in bizarrely unsafe and inexplicably useless ways.

Let’s ignore the fact that the Dark Side is completely incapable of learning from its mistakes. It’s called redundancy by design. Your enemy should not be able to find one thing to destroy and take down the entire base. So stop putting the same flaws in base designs. Also, for goodness sakes, get better computer network security.

No, what I really want to talk about are the catwalks. The Dark Side has completely inexplicable, unsafe catwalks installed in their bases. I am ignoring the huge, unused, exists-for-no-reason chasms that always seem to be in the bases. Most bases are about using all the space they have. Good to know the Dark Side has space to waste. Anyway, those chasms always seem to have one or possibly two catwalks. The catwalks don’t seem to exist for productive reasons because if so, there would not just be one when the chasm is something like 50 stories high. You would want to move people or things on more than one level. Also, the catwalks are about the width of one person. They never seem to be wide enough for two people to pass. That is fairly stupid design. If it was a narrow chasm, then that might make sense, but when the chasm is a hundred times bigger than the catwalk, surely you can make the catwalk a little wider.

Now let’s talk safety. Yes, I get it. These are bases, so they are not designed for children, disabled, or comfort. That doesn’t mean you can’t have handrails, safety rails, safety cages for your wall ladders, etc. Safety is not just to protect stupid people, although that at times is a big part. People trip. People are holding something (like a prisoner, say) and can’t completely see where they are going. Don’t try to tell me survival of the fittest. From what I can tell, the Dark Side seems to most appreciate Storm Troopers who just follow orders and don’t think for themselves. They are prime candidates for people who need safety rails. People who blindly follow orders are prime for lemming-like activities. [Although lemmings don’t actually do that mass suicide thing that many people think they do, but I regress.]

If you have the resources to build the most amazingly large and destructive bases in the universe, then you have the resources to put in proper safety rails and catwalks wide enough for two people to pass.

Is there an Intergalactic Building Code? Does the Dark Side follow it? Does the Dark Side have licensed Professional Engineers? How did they get building permits? Were there inspections? Does the Dark Side have any common sense? Any engineer who approved these designs should have the license revoked. Any organization that can’t learn from its mistakes to deserve to have their stuff destroyed over and over again.

One more thing I have to say as an environmental engineer. Has the Dark Side heard of recycling? I don’t just mean because it is good for the environment. I mean why waste perfectly good resources, like I don’t know all the leftover resources on a crashed battleship? Use old resources when rebuilding, especially when you keep rebuilding the same thing over and over again.

NY East 180th Street Maintenance Shop

I was lucky enough to get the chance to tour New York’s MTA East 180th Street Maintenance Shop. The maintenance shop is located in the Bronx and is one of several shops that service NY subway cars. It was built in 1917 and has been renovated more recently. There are six shops inside the shop and 26 storage tracks outside the shop in the yard. The shop is constantly doing maintenance on the subway cars, and also while we were there at least, had two old trains inside, including one World War II (or possibly older) era train. In short, if you are a transit nerd, this place is totally cool. We got to walk alongside trains and see their underside. We got to see parts of the train that normally you never get to see, or at least you never get to see unless you are about to be hit by one.

No, I won’t #HackAHairDryer

Evidently, IBM wants to encourage women to enter science, technology, engineering, and mathematics (STEM) by telling them to hack a hair dryer. My first thought is that while I appreciate any technology company encouraging women into STEM, did they really have to pick a hair dryer? I would like to give them the benefit of the doubt that it’s a cheap piece of electronics, but let’s be real. By picking a hair dryer, they are reinforcing stereotypes about women and how we care about our looks. I initially thought I don’t even own a hair dryer, then I realized I may own two. I know there is one in my guest bathroom, left by a relative, and it sits there in case any guest wants to use it. I may have one of my own in my bathroom, bought over a decade, possibly two decades ago. I am not even sure if I still have it because it has been a decade at least since I have used it.

My second thought about #HackAHairDryer is, YOU’RE A FREAKING COMPUTER COMPANY! ENCOURAGE WOMEN TO WRITE CODE OR HACK A COMPUTER IN SOME WAY! Computer science is one of the most underrepresented fields, even among STEM fields, it is one of the worst. For goodness sakes IBM, you are a computer company, encourage women into computers. That is a field you should know rather well. Surely you can think of things women can hack in your own field, things that will not play into stereotypes.

My third thought is what age is this campaign aimed at? Hair dryers use electricity, and they produce heat. They are not exactly the safest things to hack. In IBM’s video, there are a few scenarios for “hacked” hair dryers that quite frankly worry me a bit. If a girl or women wants to hack a hair dryer, great, but I hope there is someone (man or women) around who would know when they are getting into dangerous territory.

I can MacGyver with the best of them. In truth, a whole lot of my hacking knowledge did not come from school. It came from playing with things, looking things up on the Internet, and talking with other people with experience. I don’t “hack” that much. I do have a propensity to take things apart just to look inside and see how they work, which is easy. The difficult part is getting them back together again and having the thing still work as intended.

A final thought I have is aimed at any inspiring engineer. If you don’t like to hack, if you have never hacked anything, my personal opinion is that this means nothing to your aspirations to be an engineer or scientist. Don’t let anyone tell you, you can’t be an engineer or scientist because X. I can’t remember hacking a single thing before college. I can’t remember hacking a single thing as part of my undergraduate or graduate school experience. My education did involve some hands on stuff and science labs, but it did not involve hacking. Most of engineering education is theory and reality of design. That is, first you are taught the theory as to how something should work. Then you are taught how it doesn’t always work like the theory, so here are some empirical equations with fudge factors that do work. Now throw in some safety factors. Ta la, you have your design.

So young women, hack if you want to, whatever it is you want to hack. Explore the world. Stay curious. Learn how things work. Learn ALL subjects and find the ones that interest you the most, no matter what they are.

IBM, back off the hashtags. Do something actually meaningful that will encourage women into STEM like sponsoring science fairs or building competitions or sponsoring college scholarships.

Castillo San Cristobal

On my last day in Puerto Rico, I explored Castillo San Cristobal, a fort built by the Spanish to protect San Juan from attack by land. It was built between 1634 and 1790, and then the U.S. added a few concrete additions during World War II. The fort is huge and has a series of tunnels. Some of these tunnels are huge, connecting the different levels and areas of the fort, and were designed to have defensive explosives. Some of the tunnels are really small, and you have to stoop to move through them. If you ever get a chance to visit, try to get one of the ranger guided tours of the tunnels. Those tours besides being very informative, let you go inside some of the really small tunnels in which you normally aren’t allowed.

Viejo San Juan

It wasn’t until I walked around Viejo (Old) San Juan, especially the perimeter of it, that I realized how it really is a walled city. El Morro guards the entrance to the bay, but the fortifications encircles the entirety of the old city. One of the few ways, and the historic way, from the sea level to the city is through La Puerta de San Juan. Walking through the La Puerta, you realize the fortification is serious fortification, as La Puerta is almost a tunnel in terms of the distance you must walk to go from the sea side to the city side. The fortification is truly impressive with the wall thickness and garitas and small openings for guards to stand ready. One modern day bonus of the fortification is that it must help protect Viejo San Juan from any hurricane storm surge. There is a promenade that follows the wall from its beginning on the bay side and ends on the ocean side of El Morro. It gives spectacular views of the fort and the water as well.

El Morro

I’m on my first visit to San Juan, Puerto Rico. Today we visited Castillo San Felipe del Morro (El Morro), a fort originally built by the Spanish to guard the entrance to San Juan Bay. The original foundation was laid in 1539, and it was modified and enlarged over 250 years. The United States then added to it during World War II. Finding out that a fort this old was modified and used during WWII surprised me. I was born long after WWII, so I forget that our military has advanced a great deal in terms of technology used since then. The fort is impressive. It has six different levels and is incredibly well built. I am impressed with those people who built it with the amount of stone and brick that must have been laid.  Currently it is maintained by the National Park Service and guarded by iguanas, who by the way like to have their photos taken.

This Toilet Given to the Glory of God

Years ago, I lived in Austin and went to a historic Episcopal church. The parish house needed major renovation, and when the parishioners were surveyed for what they wanted from the renovation, more and better bathrooms was at the top of the list. Considering how few and far between the bathrooms were, this request was predictable. Like others, I donated money to support the renovations, and the new parish house was wonderful, and the multitudes of new and bigger bathrooms were glorious and much appreciated.

My current DC area Episcopal church is also historic with a parish house needing major renovations. Once again I find myself being asked by my church to donate money to support renovations. The space is small and not used efficiently partially because the parish house is an old house. It has this tiny little ancient elevator that scares me. Also like my former church, at or near the top of everyone’s wish list is more and bigger bathrooms.

As I’ve contemplated how much money I want to and can give, I’ve also thought about what I’d like to sponsor if I had enough money to request something being acknowledged as being sponsored by me. I don’t actually know if anything in the renovations will be designated as being sponsored, but churches do that all the time with big donations. The church has brass plaques on all the pews, stained glass windows, and other items.

So I’ve thought about it just because it’s fun. The same way I think about if I died famous what would I’d like dedicated to me. I’ve already decided should I die famous that it will be written into my will that if anyone tries to name a freeway after me, my estate will sue them for defamation and pain and suffering, and I’ll come back to haunt them. A park or library would be lovely, but a freeway would be an insult.

I realized what I’d like to sponsor at my church. I want to sponsor the new toilets. I want a plaque next to a toilet that reads “This toilet donated in glory of God by GGE.” As much as the vast majority of people don’t want to think about toilets, when there are not enough, or they are not working, they are all you think about. I speak for all women when I say public places never have enough of them, and we spend too much time in line to use one. [More of my Opinions on public restroom design.] We have all sorts of euphemisms to avoid having to say the word toilet, and God forbid someone should mention the words urine or feces or urination or defecation in polite company. I’ve spent years in the lab analyzing urine and spent part of my career in wastewater treatment and conveyance. I could speak for hours on bodily human waste.

The truth is the toilet is one of the greatest inventions of all times. It effectively and efficiently takes human waste away to where it can be treated and not spread disease. Toilets prevent smelly and dangerous gases from the waste from coming inside. Humans no longer walk outside avoiding streams of human waste and falls from above from people emptying their chamber pots. Because of toilets and sanitary sewers and treatment plants, most of us do not have to worry about cholera, typhoid, Guinea worm, and many other diseases.

Be thankful that you have a toilet. When my church’s renovations are over, I know all the members of the parish will be grateful we have more of them.

“These toilets given to the glory of God and in appreciation of the past, present, and future people who ensure bodily human waste is removed from this premises and properly treated, by an environmental engineer who understands a toilet’s importance.”

Preparing to Brief Top Boss

I’ve been working on this project at work for over a year now that seems to keep getting more and more important because of the effects of it. Recently I learned that Top Boss wants a briefing on it, and my presence is requested at the briefing. Top Boss would be the head person where I work. I work at a large place with somewhere on the order of 15,000 employees. I have become the subject matter expert on this project. Thus I need to be there because if Top Boss asks any technical questions, I will probably be the one who needs to know the answer. When I first learned that I would need to be at Top Boss’s briefing, I wasn’t nervous about it. If no technical questions are asked, I will happily sit quietly in the back as management talks. If technical questions are asked, I know my stuff. I’ll have my notes, and I feel confident I can sufficiently answer whatever might be asked. I don’t know if I should feel excited to brief Top Boss because I never thought I would end up in a meeting with Top Boss. Honestly thought it just feels like another management briefing. I am hopeful that this briefing will at least allow us to get some documents out that we have been trying to get out for a while now.

No, my first thought when learning I would need to be there was, crap, I hope I am not supposed to wear a suit for this because I don’t own a suit. I immediately looked around for a coworker who might know the dress code to brief Top Boss. The first coworker I see happens to be a straight male soil scientist, whom I called Dave. This may seem like an absurd choice, but I put Dave at the middle to high end of straight male scientist and engineer dress spectrum. Unlike some I have worked with, his clothes fit him properly and are appropriate business casual, and I have never seen him in a tie that makes you wonder if he lost a bet. However, I don’t remember ever seeing him in a tie. Dave however is kind of an appropriate choice in that Dave and I constantly seem to show up to work in similar outfits. There are two other scientists who also seems to constantly dress similar to both of us. We all show up to work in khaki pants and and a green top, or black pants and a blue top. You get the idea. We are not adventurous dressers. I wear more jewelry and other accessories than any of them though. Dave and I also shop for clothes similarly. I go to Costco, find a pair of colored denim pants, and once I determine they fit me well, I go back and buy them in several more colors. Same for tops, but those normally come from Kohl’s. I have the same short sleeve top in six colors and similar for long sleeve version and my sweaters also. My few unique pieces generally come from a thrift store or flea market. I will admit to having too many scarves and pashminas, but they are all unique, sometimes come from my travels, and keep my warm in the always cold office building.

I don’t know enough soil scientists to know if Dave is a typically dresser for a soil scientist. Geologists seem to have an unnatural obsession with Hawaiian shirts. Male engineers tend to wear neural suit pants and a white top. They then have two or three ties hanging on a hook in their office. If there is a third tie, there is a good chance it will involve Snoopy or some other cartoon. In any event, Dave assures me that office casual should be fine. However he also said he has never been in a meeting with Top Boss. I may seek a second opinion just to be sure. I will probably ask my boss. He is a good dresser. He has a science background, but he is also Italian. More importantly, I think he used to work as an advisor to upper management before, so he probably knows what is normal dress.

I’ve heard that you should dress for the job you want, not the job you have. I have the job I want. I suppose if I was really to dress for the job I want I would wear a hard hat, gloves, jeans, and a t-shirt that I don’t mind getting covered in dirt, or I might wear a lab coat, goggles, gloves, and have a pipetter on my hip. I am fairly sure these outfits will not work to brief Top Boss.

Brooklyn Navy Yard

As part of Open House New York, I got to wander around the Brooklyn Navy Yard. The old navy shipyard is being redeveloped for commercial use. There are several dry docks, and one dry dock is still operational. There is also many green features includes renewable power. However, the site is quite simply a really cool place to photograph.

Brooklyn Army Terminal

As part of Open House New York, I toured the Brooklyn Army Terminal. It was built at the end of World War I and was a huge military base that was used to transfer people and materials from land to sea. It was built in an entirely utilitarian design and in the incredibly short time of 17 months. However, its utilitarian design is what I find incredibly interesting. Building B has this huge atrium with two sets of railroad tracks. Trains would travel directly into the building where material would be off and on loaded from various levels. There are several bridges connecting several buildings so that material could be moved between buildings on vehicles without interfering with the train traffic below. The atrium is dramatic, and I love that the concrete pour lines are visible.
