NMNH Cetacean Collection

Posted on August 25, 2014 by geek

Friday I got the incredible opportunity to take a behind the scenes tour of Smithsonian Institute’s National Museum of Natural History. They let a small group of people take a tour of the cetacean collection stored in an offsite location. NMNH has the largest marine mammal collection in the world, and it is awesome. [More properly said, the people of the USA have this amazing collection, and NMNH has been endowed to take care of it.] Most of their specimens are not on display to the public but are stored offsite and in a manner where they can easily be studied. Charley Potter and Nick Pyenson, scientists at NMNH, showed us many of the cetacean specimens, talked about what they do, and answered our questions. I want to thank NMNH and their staff, especially Hilary-Morgan Watt, Katie Sabella, and Trish Mace, for letting us take this amazing tour. Also, thank you to Steve Thornton, a visiting researcher, who gave us a detailed description of how dolphins use their nasal passages to make noises, which at least in my humble opinion is fascinatingly and amazingly complicated. Also, I would like to thank them for having their specimen collection online. I missed some of the species names of specimens we looked at, but because the specimen number was visible in some of my photos, I was able to look up information about the specimen through their website. This is an incredible resource.

They had two bottlenose dolphin skulls out sitting side by side. One was from a coastal bottlenose dolphin, and one was from an offshore one. When sitting side by side, it was easy to see how much smaller the coastal one was than the offshore one. The morphological differences relate to their different eating habits, as the offshore ones feed on larger animals.

They had part of a forelimb bone from a right whale. The fungal like growth on it was bone that had grown around something on which it had been entangled.

There was a drawer filled with narwhal tusks. Only males have the tusks, and most twist in the same direction. Most have a polished end. Up close they really pretty and have interesting texturing. They are hollow with varying diameters.

In the same cabinet as the narwhal tusks are pieces of baleen. Baleen can be used to distinguish different types of whales and is fast growing like hair. Examining the baleen can give information about the trophic feeding level of the whale and can give up to 40 years worth of information on the whale and water conditions, by analyzing it along different points along its length. Before plastics and fiberglass was invented, baleen was split into rods and used in such things as umbrella skeletons, of which they have one.

Baleen, Charley Potter is holding one piece. In box in drawer is an umbrella skeleton made from baleen.

They have an amazing collection of skulls. There are skulls upon skulls filling up shelves. The skulls are placed side by side by species and thus can compared easily. There were numerous Baird’s beaked whale skulls that had various shades of white and off white depending on the conditions in which they were found.

The Blainville’s beaked whale skulls were really interesting. The males have two giant, erupted, modified teeth on their jaw, which are used for combat. The beaked whale skulls are the only skulls which can be sexed. The males have very dense skulls and thus are quite heavy when compared to the female skulls that were approximately the same size. They let us life each one by the beak, and the difference was really obvious.

They were still processing some specimens. There was a pilot whale skull out that had a lot dried soft tissue attached to it.

There was another skull sitting next to the pilot whale skull that was some type of beaked whale. I was completely fascinated by the porousness of the bone.

There was also a bag full of vertebrae. I don’t know what species it was from, but the pattern on the vertebrae was really interesting.

In an adjoining building they had the bones from the really large whales. The building was complete with a giant garage type door through which to bring the specimens. There were shelves filled entire vertebral columns from various whales. On the floor was the skeleton of a right whale.

Right whale bones

All the skulls were propped up on metal carts. They were placed vertical for easy study. Because of the way a Sei whale skull was placed vertical, the radiating lines on the palette could be easily seen. All baleen whales have these lines, and the lines house blood vessels and nerves that feed the baleen.

There were several gray whale skulls all sitting next to each other. The skulls were collected from various years and includes one from pre-1850s. The genetic makeup of the whales before and after the whaling industry can be compared, and it will give information about the genetic bottleneck that occurred due to whaling and the diminished population.

Gray whale skulls

They also had a blue whale jaw bone that is not only the largest blue whale jaw bone ever collected, it is also the largest single bone ever collected from any creature that has lived on Earth.

Finally there was a North Atlantic blue whale skull, which was just amazing to view. It completed dwarfed us when we gathered for a group photo in front of it.

Bad Restroom Design Example

Posted on August 17, 2014 by geek

Some time ago, I wrote about female public restroom design basics. I am so tired of walking into badly designed female restrooms, and I wanted to give a primer to what women in need in a public restroom. We don’t need fancy. We need functional. Based on the comments to my post and also one of the most hilarious Twitter discussions I have ever had, men’s restrooms are badly designed also.

Last month one day, I was working in an office building that was not the one in which I normally work. It was an older building. I won’t say which office building it was, but it was in Washington, D.C. It was the perfect example of bad public restroom design. It was the perfect example of not updating elements that could be easily updated. Thus, of course, I had to take photos and share with everyone why it is a perfect example of bad restroom design.

Toilet stall so short, one must climb on the the toilet to close the door

First, it had toilet stalls so short, a woman has to either stand on the toilet or squeezed in between the toilet and the stall wall to close the door. I still don’t understand how the original designers just can’t understand door swing distance and the area of a human footprint needed to be in stall length calculations.

The sinks: 3 sinks with separate hot and cold water faucets and 2 working soap dispensers at the ends

Then it had three sinks with only two soap dispensers, both of which were on the far ends of the sink areas. Thus, a person who uses the middle sink needs to either go to the end or reach across another sink to get soap. In defense of the original design, each sink did originally have a soap dispenser above each, but those are now non-functional. Instead of replacing the non-functional soap dispensers, they just put new ones at the end. It should be noted that by either changing the mirror or finding a smaller soap dispenser, the middle sink could have its own soap dispenser. Thus, the renovators of this bathroom do not get an excuse for the soap dispenser stupidness.

Next, also shown in the above photo, there are separate cold and hot water faucets. I am not sure if separate faucets originated before mixing valves were created, but that is the only reason I can think for their existence. However mixing valves exist now, and thus there is no point to the continued existence of separate hot and cold water faucets in a public restroom sink where a person is never going to be filling the sink with water to then wash their hands in the water filled sink. While it would obviously require taking out the sink and faucets, to change the plumbing to include a mixing valve, it could be done. Depending on the piping, it is possible it would require taking out some tile to change the plumbing, but it could be done, and it is not a massive renovation, and it would make the sinks so much more functional.

The inexplicable couch

Finally, the restroom had a couch. Old buildings always seem to have couches in the female restrooms. Because women often get the vapors and need a lie down while we clutch our pearls until some savior arrives with smelling salts. Or something like that. Could you lie down on most of these couches? No, they are generally love seats. Would I lie down on any of these couches? No, I would never even touch most of these couches. But it fills the space, which seems to be only point of these couches.

Montreal

Posted on August 10, 2014 by geek

While we spent a good portion of our Montreal visit in Old Montreal, we did spend some time wandering around other parts of the city. (Also, see previous Parc du Mont-Royal post.) The Montreal Plateau could probably be considered the original suburbs and has beautiful townhouses and various ethnic areas. Downtown (Centre-Ville) has a lovely mix of old and new buildings and some nice parks that give much needed green space.

Basilique Notre-Dame de Montréal

Posted on August 9, 2014 by geek

While visiting Old Montreal, we visited the Basilique Notre-Dame de Montréal (Notre-Dame Basilica). In my opinion, while the outside is pretty, the outside is somewhat deceptively plain compared to the beauty inside. The inside is gorgeous. There is just amazingly detailed decoration everywhere. There is beautiful wood, gilding, colors, paintings, stained glass, statues, and more. You name it; it is there. Much of the detailed decoration on the walls and ceilings is really well done trompe l’oeil. Then behind the church is the chapel, which has a sort of gilded modern decoration. While the church is bathed in a blue light, the chapel is bathed in a gold light. The builders and artists who built and decorated the basilica really did any amazing job.

Old Montreal

Posted on August 8, 2014 by geek

I spent much of my short visit to Montreal just wandering around Old Montreal (Vieux-Montréal). I love old buildings, and Old Montreal certainly has plenty of them. It has lots of charm, cobblestone streets, cafes, and shops. It sits right on the St. Lawrence River, and there is a wonderful linear park that separates the river and its quais (wharfs) from the main part of Old Montreal. It is just a lovely place to visit and walk around.

Sleeping Ferdinand

Posted on August 7, 2014 by geek

I finally got a video of Ferdinand sleeping where he is making some of his weird noises. I am still trying to get one of him when he is doing his muffled barking. He isn’t snoring in this one, just weird air blowing or something. I wonder if he is dreaming, and if so, what about.

When an engineer gets to comment on building maintenance

Posted on August 6, 2014 by geek

One nice thing about where I work is that we get to fill out surveys about how we like the building we work in and comment on it. I have my doubts about how much they act on the survey results, or how much they pay attention to the comments if an employee bothers to give comments, but hey, it’s a great place to vent. I actually for the most part like my building. It is relatively new and doesn’t have the problems that many older buildings that my employer has has. It is kept clean and and looks nice. One big problem I have with it is the same that I have with almost every other office building: the temperature is set at a temperature that is comfortable for men not women. By about 11 am, once the HVAC has fully gotten the ambient air to the set point (as opposed to earlier in the day when it is ramping up after having been off during the night), the vast majority of women are walking around in sweaters, jackets, or blankets that all of us keep at our desk. [Spoiler: When I rule the world, I will dictate two things. Office buildings will be set at temperatures that are comfortable to women, not men. Also, public restrooms will be designed better. In particular, the stalls will be longer so that women don’t have to climb on the toilet to close the stall door. Truthfully there are many things that need to be improved in public restrooms, most of which I and many other people have covered is this somewhat comical, somewhat serious past blog post.] However, the building I work in has some of the worst plumbing issues I have ever seen, especially for a building that is less than ten years old. Ironically it has LEED certification, but whoever certifies it appears to ignore the obvious water wasting issues it has, as I detail below. I’ve decided to share below the comments I gave in the building survey, not because it will really accomplish anything, just as a way to vent and possibly to serve as a warning why if you let an engineer comment on a building with design and maintenance issues, you may get more than you wanted. Thus, my full comments are as follows.

With all the dual flush toilets, only one flush button actually works. With some toilets it is the half flush button, with some the full flush button. However whether or not the working button is actually whichever button it appears to be is unclear, or if they have possibly all been disabled and all converted to full flush. They constantly run. Almost every time I enter a restroom, I have to push the flush button on at least one toilet to get it to stop running. The restroom auto soap and water sinks are like sink roulette. Which sink will give me soap? Which sink will not continuously squirt soap at me? Which sink will give me water? It takes forever to get repairs done on issues in the pantry/kitchens. It took them two weeks or so to put a new aerator in the sink faucet. A part that can be bought at any time at Home Depot. It is not special. Maintenance blames pantry sink issues on reasons that are not the problem. On numerous occasions, water has come bubbling up from the drain pipes into the sink. Sometimes so much water has bubbled up that the sink has overflowed with disgusting brown wastewater. Then maintenance posts signs saying not to put coffee grounds down the drain as that caused issue. While coffee grounds will cause a sink with a bad garbage disposal to not allow the sink to drain (and putting coffee grounds down the drain is a bad idea), it will not cause water to flow up from pipes below. (I’m a chemical engineer I can prove this with fluid dynamics equations!) There is obviously some issue with the drain pipes below our floor, which any competent plumber or chemical engineer could tell you.

While there was no place to attach photos or videos, below is a photo of the backed up kitchen sink and video of it overflowing.

Parc du Mont-Royal

Posted on August 3, 2014 by geek

After spending some time enjoying the tam-tams, I went further into Parc du Mont-Royal to do a little hiking and to visit the overlooks that I had read have amazing views of the city. The park is on part of a mountain, so the overlooks have wonderful views of the city below on the plain. The Camillien-Houde lookout gives views of the northern half of Montreal Island, and the Kondiaronk lookout gives views from the northeast and southwest including downtown Montreal. I wished I had had more time to hike as much of the park is a dense forest. It is a wonderful park and oasis, akin to New York’s Central Park.

Montreal Tam-tams

Posted on August 2, 2014 by geek

After my week in Burlington, I made a short, first visit to Montreal. I must admit, I had a few preconceptions about Montreal. I don’t know if my preconceptions were because Montreal is the largest city in Quebec, and I associate French speaking with more cosmopolitan or because of some of the history and politics of Canada and Quebec. In any event, I’ve been to Toronto, Vancouver, Victoria, Halifax, and a few other places in Canada, but I wasn’t sure if I would like Montreal as much as I have liked the other places. All my preconceptions about Montreal pretty much flew out the window mainly due to the fact that one of the first things we visited on the first day of sightseeing was the Sunday afternoon Tam-Tams in Parc du Mont-Royal. I had read about the Tam-tams in Lonely Planet, and they are sort of scheduled spontaneity of drumming and a few other musical instruments. People just come and start making lovely music, and then other people come and start dancing to the music. It seemed like a bit of a hippie-fest, and that characterization is not meant to be derogatory. I had no idea so many hippies lived in Montreal. It was really fun to watch, and if you are ever in Montreal on a summer Sunday afternoon, I encourage you to go to George-Étienne Cartier Monument in Parc du Mont-Royal. Just don’t blame me if you start dancing around like a nut.

This child was watching the adult dance with clear curiosity.

Adults brought little drums out of nowhere to try to get these kids to drum. The kids were not clear on what they were supposed to be doing.

I loved his mobile drumming setup, complete with bicycle wheel and I think frying pan.

This guy seemed like a very serious drummer.

There seemed to be a “main” group of drummers on the benches and then “back up” drummers sitting on the wall.

I assume he did not cart the drums because people were throwing trash in the drums, but this guy was the epitome of a cool drummer.

Yes, there was cowbell.

The “main” band.

Also, the tam-tam was not the only activity occurring in that area. There were people walking on a tightrope (attached to two trees) and a group of people doing some sort of yoga, gymnastic, balancing thing. Also, there was a guy creating very large bubbles.

Burlington Uniqueness

Posted on July 28, 2014 by geek

I have already written how nice a town Burlington, Vermont is and how much I love its colorful houses. I just had to add one more post with a few photos of some of fun, arty, and unique things that I saw there that help to make it a cute town.

First, on Church Street, there is this water fountain which is probably one of the most unique and beautiful public water fountains that I have ever seen.

Then there is this box on Church Street where you can put donations for the less fortunate, and it is of course designed to look like Champ, the famous monster of Lake Champlain.

Donation box that looks like a very cute Champ

Then there are these paintings on a commercial building that are by far the best way to incorporate electrical boxes into the exterior design of a building that I have ever seen.

Then finally there is this sign that I spotted several copies of on Church Street. I have no idea if the second part is actually written into the Burlington ordinance, but it would be awesome if it was.
