Morocco

In December I went to Morocco with Kathy, Ric and Rachel. We visited Tangier, Tetuan and Chefchaouen (The Blue City). I enjoyed it so much, I was happy when Laura found a package tour to Morocco for Spanish language students (which we both are, since we are enrolled at affiliated Spanish language schools). We booked it and left for a 2.5 day trip to Morocco on Fri. We caught the tour bus about a 10 min walk from the flat Fri morning around 9am. As expected, the trip was largely populated by American college students in Sevilla for their study abroad semester. The majority had been in Sevilla only about 6 weeks. We were definitely the oldest in the group, but since we've both been teaching at the college level our whole professional lives, the generation gap was easily overcome.

We drove south for about 2 hours to La Línea de la Concepción, a Spanish town that abuts the "British Overseas Territory of Gibraltar". In the bus station I had to take a picture of this vending machine that not only had the usual soft drinks, but also a row of beer. I didn't see any way to prevent vending to the under aged, so local kids must love this place, haha:


Walking out of the bus station, you can see the "rock of Gibraltar" peaking out from behind the buildings:


The park in front of the bus station was cute:


We walked to the border with Gibraltar, waved our passports and got on buses to go out to the tip of the peninsula of Gibraltar. The weather was clear, but windy. The mosque at the point is lovely:


I liked this sign, not only for its information, but for its distinctly British sounding title, "Some of our more regular seabirds":

Situated at the mouth of the Mediterranean Sea, this lighthouse serves one of the busiest shipping lanes in the world as ships move back and forth from the Atlantic to the Mediterranean:


The rock of Gibraltar is a massive limestone outcropping. The caves of St. Michael are garishly lit, but impressive:


Outside the caves, Barbary macaques abound. These monkeys are all over this part of the rock. They have no fear of tourists. Indeed, despite being told by the bus drivers and tour guides to not interact with them, this bus drive coaxed one of the monkeys onto the shoulder of one of the students in our group:


Here's a monkey on the other side of an iron fence. That worked for me:


In the town of Gibraltar, Laura and I watched some glass blowers make a collection of beautiful crystal vases:


In a small space, you have to make use of every square inch. Here the sidewalk went across the tarmac of the only airport--literally across the runway. When planes landed, traffic signals and gates blocked cars and pedestrians from crossing. After they taxied out of the way, the road would open up again:


Back on the Spanish side, we took a ferry across the Mediterranean to the Spanish town of Cueta which is on the African continent. We even took our tour bus with us:


Here is Gibraltar as we sailed by it on the ferry in the dusk:


Once in Cueta, we got back on our bus and traversed the Moroccan border (which took a looonnngggg time, 2.5 hours) and drove to our hotel in Tetuan (only about 35 km from the ferry port). Here's the view from our room. There was a major road construction project happening right outside the window:


On Saturday, after a hotel breakfast we left around 8am and headed to the city of Tangier. We drove through it, but didn't really stop. Instead, we went to the Atlantic beach and rode camels on the beach. It was pretty cool. The best part is that the kneel down for you, you climb on relatively easily and the stand up:



Me and "my" camel:


Near the same location, we stopped at Cap Spartel, this is the point where the Mediterranean and the Atlantic meet. Not surprisingly, there's a lighthouse here too:


Here's Laura jawing with some of the students in our group:

 From Cap Spartel, took our bus to Chefchaouen (The Blue City). Here's a picture of one of the many market squares in the medina. The mountains looming behind the city are beautiful:


It's called The Blue City for a reason:




The sunset was beautiful:


After Chefchaouen, we took our bus back to Tetuan for a dinner for the whole group. It included some traditional music, dancing and other entertainment. The dining room was quite ornate. The food was really good:



After dinner, we went back to the same hotel in Tetuan.

This morning we  woke to cool clear weather in Tetuan. We were guided through the Medina of Tetuan:


The medina is a maze of stalls, markets, homes and people. Our guide pointed out this double row of bricks at one point during our walk. He said that two rows means your on a commercial street, one row means residential/dead end, three rows means it leads to one of the seven exit gates of the medina wall:


While interesting, I don't think it really helped me to navigate the city any better, haha.

We stopped at a "farmacia" where the proprietor pitched a variety of spices, oils, perfumes etc to our group. After a while, I left the presentation and hung out on the street with our Moroccan guide. I also snapped this picture of the "convenience store" across the street:


The stall sold a lot of the same kinds of percussive instruments that we observed at our dinner show the previous evening:


Here are a couple of the students we were friendly with during the trip:


These are the hills of Morocco as we drove out of Tetuan and back to the ferry port:


There are public restrooms at the border crossing. The lines of cars are so long and slow that there's plenty of time to jump out and go to the bathrrom. This is a unisex urinal. I've never seen one before, but, according to female students on the bus, they stood on the foot spots and squatted over the hole. When I used it, I just aimed for the hole:


Back on the ferry, we were both pretty wiped:


The bus ride home was uneventful and we made it back to the flat around 8pm. A busy few days, but a fun way to see Morocco.

Chair Repair

Mario dropped by this evening and took one of the chairs for repair. Seems like he's going to do one at a time. He lives about a 5 min walk from here, so he just picked up the chair and walked back to his place with it. Since 3 of the 4 need help, I guess we just started about a month-long process, if we're lucky.

***

Speaking of month-long processes, Feb is now coming to a close. Tomorrow begins the final third of our year in Spain. Time flies.

***

Speaking of February, Walla Walla has experienced what is likely the coldest, snowiest Feb on record there. I just keep thinking, glad I missed that!

***

I finished reading Everybody Lies by Seth Stephens-Davidowitz. Pretty good. Moving on to Hello World by Hannah Fry. I'll keep you posted.

***

Today is a holiday here in Andalucia, but only here in this province. It's called, aptly, Day of Andalucia. It essentially commemorates the founding of Andalucia as an autonomous province of Spain in the year 1980. For us it means no language class, less traffic in town, more pedestrians/tourists on the streets. Lovely weather for it though:


***

Packing for a weekend guided trip to Gibraltar and various points in Morocco. Should be fun. Glad Laura's getting a chance to visit the Blue City in Morocco.

Fuzzy Structures

 Tried to prove a conjecture today only to realize that an ortho-convex set might not even be connected. This is something you take for granted with ordinary convexity. I still think my conjecture is true if I add "connected" to my list of assumptions, but you always have to be careful in math. Here's an example of an ortho-convex set that is not connected:


After class, I took a walk towards the fairgrounds that Laura visited yesterday. Along the way, I found this old mosque attractive:


As Laura noted, though the fair isn't until May, the construction on the fairgrounds is well underway. I was struck by this mass of scaffolding that promises to be perhaps the main gate to the grounds when all is completed. It's interesting how, with the scaffolding, the structure almost looks fuzzy:

Expired Registration

About an hour after I went to bed last night, Rachel noted to Laura that the registration on the Honda had expired. Given that the registration is due each June, that would make it really expired. Laura woke me up to let me know. It's weird how you can be 100% sure of something and still be wrong. Well, I was 100% sure I had renewed the registration before we left Walla Walla. I still, even now, seem to have a memory of putting the new sticker on the license plate. However, after searching my records (credit cards, checks etc) in the middle of the night, I was forced to acknowledge that somehow, I didn't renew the registration on the car. So, changing tack, I started figuring out how to renew it. Turns out, it was pretty easy. Just do what I would (and should) have done back in May/June, log on the the registration renewal site and renew the registration. I did that. The registration will go to our house in WW. I gave Halley a heads-up to forward it the Rachel ASAP. And, Rachel will have to cross her fingers that she can make it through another week or so in Miami without getting pulled over by a FL cop for having an expired tag. (Given that she's made it 8 months, there is some reason to hope that she'll make it another week.)

***

Speaking of paying things on line for our WW life. The property tax bill came today (electronically). That one I paid right away, even though it's not due until April. That definitely a bill you don't want to miss. I relayed to Rachel after paying the registration that this was only the second time I'd ever missed a payment. The first time was a missed credit card bill the month that Emily was born. I supposed lots of people go through life never missing a bill, but I guess missing two in a span of 30 years or so of paying bills isn't the end of the world.

***

In a completely unrelated matter, the chairs in our flat our falling apart:


The joints and cushions all do this to one degree or another. Mario intended to get them repaired way back last summer when I pointed it out to him, but I guess it just slipped his mind (and we didn't really pursue it either). Anyway, we started with 4 of them, but at this point, there's only one left that is really safe to use. I finally sent Mario a message this morning about it. He apologetically said that he'd get right on it. I'd be happy to fix them myself, but I just don't have the right tools.

Math History

I spent most of the day reading about the math history of the idea of "center of gravity". I'm hoping to include a nice overview in the paper I'm writing. Turns out the first recorded mathematical treatment is due to Archimedes in the 3rd century BC. Archimedes of  "give me a long enough lever and a place to stand and I can move the earth" fame. Turns out, that has a lot to do with centers of gravity. Folks in the middle ages sort of rediscovered Archimedes and started applying methods of infinitesimals to the problem of finding centers of gravity of solids. Indeed, their methods were important precursors to the discovery of calculus, particularly the work of Leibniz in the 17th century. It's fun to read about these ideas and at the same time routinely encounter buildings here in Sevilla that predate the development of calculus by some 300 years.

***

There were two new students in my Spanish class today. We had a nice time exploring the past tense of verbs like "me gusta". Not sure I could get it right in an extemporaneous conversation, but at least I understand the grammar.

***

Didn't walk/run too much today. Still resting a bit of  a foot injury. That said, the two walks I did do today (about a mile each) were essentially pain free. I'm optimistic that I'm past the injury now.

***

The winter in Walla Walla won't quit. Normally, this time of year, daffodils are blooming and buds are developing on trees. Instead, it just keeps snowing and giving sub-freezing weather. I'm glad I'm missing it.
