Pictures of the MSW Robotics Team at the 2012 Maryland State FLL Tournament

The MSW robotics team is in red shirts. In some pictures, you see them from the back, with "MSW" printed on the shirts. In the first picture, you can't really see the team, but they are standing on the upper level, in the back, underneath the two yellow and black signs.

This is a movie that Fox45 took of the last regular match of the tournament. Partway through, a team mate is interviewed. After that, the MSW robot is shown knocking over some little purple Legos. After that, you can see the MSW team cheering.

Sunscreens from 2011

I'm staring at the sun blocks that are left over from the summer. I want to remember which ones are left because we bought new bottles at the end of the season, and which ones are left because we forgot to throw them away.

Sun block testing strategies included using right before getting in an outdoor pool, using right before getting in the car to go swimming, using after swimming 10 minutes and with wet skin, and occasionally remembering to re-apply after 2 or 3 hours. Some testers swam with sunscreen on for 1-4 hours. Other testers sat in the shade or stood by the pool for 1 to 3 hours. Generally, these products did not cover well on wet skin. Most have a faintly white color which will release onto the black car interior. Sun burns mostly resulted from not applying sunscreen to an area. There were very few sun burns after using sunscreen, even though it was rarely reapplied.

Sun block sprays were rejected because they were costly and wasteful, and they made testers cough.

Products were always chosen with an eye toward a higher SPF, and ingredients that protect against UVA rays (titanium dioxide, zinc oxide, avobenzone).

Products did well when they smoothed on skin easily, were easy to use on all exposed skin, didn't hurt the eyes, didn't feel strange, didn't smell horrible, and were easy to put on by younger testers. Keep in mind that a lot of products will hurt the eyes if they've been opened for a while. Once last summer's bottle has been opened, it may hurt the eyes next summer.

The best sun screens we tried last summer were (drumroll, please):

No-Ad, big orange bottle, sport lotion with a claim to water and sweat resistance. This lotion is currently replaced by their big blue bottle, which has a higher SPF. Key ingredient protecting against UVA rays: Avobenzone. I know this ingredient has been associated with an increase in free radicals, but this product smoothes on easily and stays on a long time. It didn't hurt anyone's eyes, and it is pretty cheap.

Close second: Banana Boat lotion in the big orange bottle. Another sport product that is supposed to be water and sweat resistant. Key ingredient is also avobenzone. This works just as well as No-Ad, but it is more expensive.

Best face sun screen for the extra-sensitive person: Ocean Potion's Face 45 SPF Potion. Key ingredient: zinc oxide. This cream is easy to put on and provides good coverage. It was initially rejected in favor of a stick formula, until the tester concluded that the sun block sticks didn't go on the skin as well. This cream did not hurt the eyes. The container is Recycle #7, so it may not be recyclable.

Second place finisher in the face sun block category: Banana Boat's face sun block sticks. These were easily applied and had a clear finish. Younger testers can put this on by themselves, with just a check from an older person for coverage. Key ingredient: I don't remember, probably avobenzone. Container not recyclable.

The losers?

Neutrogena Pure & Free Baby. This sun block stick probably works fine, but it has a white finish when it is applied, which some testers hated. I have two of these sticks left. I should probably just toss them because nobody will want to use them.

Aveeno Baby Natural Protection Mineral Block SPF 30. This lotion works pretty well, but it has a slightly gritty texture. You will be disappointed if you use this as a hand lotion. It is only slightly irritating to the eyes. Key ingredient: titanium dioxide. This product does not come in a recyclable container and it is a moderate to expensive drugstore product.

Biggest loser: Coppertone Water Babies Pure & Simple SPF 50. I had high hopes for this product, but when it is applied the lotion tends to stick to where it is first applied so it is hard to use quickly. It has a gritty feel, so don't use it as a hand lotion. Key ingredient: zinc oxide. Waterproof.

Note for next year: find a lotion that is inexpensive, does not contain avobenzone, and that is not irritating.

A Recipe for Rye Bread

This is the recipe I used for my rye bread last weekend, taken from the book Recipes: The Cooking of Scandinavia, published as part of the Foods of the World series by Time-Life Books, 1974.

Suomalaisleipä - Finnish Bread

To make 1 loaf

4 packages active dry yeast (I used 3 tablespoons of yeast from a jar)

3 teaspoons dark brown sugar

1 and 1/4 cups lukewarm water

1 tablespoon melted butter

1 and 1/2 teaspoons salt

2 cups all-purpose flour

1 and 1/2 cups rye flour

1 tablespoon soft butter

Sprinkle the yeast and 1 teaspoon of the brown sugar over 1/2 cup of the lukewarm water in the bowl where you will prepare the dough. Be absolutely sure that the water is lukewarm - neither too hot nor too cool to the touch. Let the mixture stand for 2 or 3 minutes, then stir it to dissolve the yeast completely. Set the cup aside in a warm, draft-free spot for 5 to 7 minutes or until the mixture has begun to bubble and has doubled in volume.

Add the remaining 3/4 cup of lukewarm water, and, with a wooden spoon, mix in the remaining 2 teaspoons of dark brown sugar, the melted butter, salt, all-purpose flour, and 1 cup of the rye flour. When the mixture forms a smooth dough, cover the bowl loosely with plastic wrap and let it rest at room temperature for 10 minutes.

Knead the dough until it is elastic and smooth. I like to do this in my standing mixer with the dough hook. Kneading by hand works too. Butter the inside bottom of the bowl, or pour melted butter, cooled slightly, into it, then put the dough in, then flip the dough over so all sides of the dough are buttered. Let the dough rest this way, with the bowl loosely covered with plastic wrap. Put it in a warm, draft-free place for 45 minutes or until the dough doubles in volume and no longer springs back when poked with a finger.

Preheat the oven to 375F. Lightly butter a cookie sheet and then sprinkle the cookie sheet with rye flour, turning the cookie sheet over to knock off any excess flour. Shape the dough into a round, flat loaf, 9 or 10 inches in diameter, and set it on the cookie sheet. Bake 1 hour, or until the bread has a dark brown crust and a toothpick or skewer comes out dry and clean. Remove to a cake rack to cool, and serve, if possible, while the bread is still warm.

Review of a bit of Michel de Montaigne

Last night the book club discussed four essays by Michel de Montaigne, who published the first edition of his essays in 1580. As his name suggests, Montaigne was French; we read an English translation.

Of Cannibals

Of Cruelty

Of Repentance

Of Experience

Montaigne writes about himself, rather than about any single topic. He even says so. He says that although he isn’t an expert about anything else, there is one topic of which he is the supreme master: Michel de Montaigne.

Although the barriers of time, culture, and translation make it challenging to begin reading Montaigne, he writes about the same issues we talk about today: the law, virtue, cruelty, xenophobia, finding the right path through life. In fact, just when I said to myself, This topic is as fresh today as it was in 1580, Montaigne would add a quote from Seneca, who lived 4BCE--65AD. There is a huge advantage in recognizing the eternal nature of our problems. Montaigne probably admired Stoicism because of its focus on virtue, but our reading did not show him to think he was a perfectly virtuous man.

Montaigne does not initiate a topic, describe it fully, explain the advantages and disadvantages, and prescribe a solution. Instead, reading his essays is like listening to a good friend after dinner. He might give an anecdote related to the topic, as in “Of Cannibals,” and then just begin writing. Recent experience, old experience, stories he’s heard, people he’s met, all become part of the story. He explains that strangers have strange customs. If they were people we knew, their customs would seem ordinary and proper. We are also distracted by unimportant details. If a person from a strange land has lots of virtues which we respect, we may still point and say, But he’s not wearing any pants!

Of Cruelty is mostly about defining virtue, although Montaigne does give several examples of cruel punishments. He suggests that cruel punishments are enacted for the benefit of the crowd watching, not for the prisoner. It would be better to torture the body of a criminal after death, than before, because torturing a person, even a criminal, only underlines the cruelty of the punisher and the crowd.

Montaigne contends that virtue is not virtue unless it has been tested. If you live a quiet life at home and have everything your own way, how can you call yourself virtuous? A person needs temptation and trial to show virtue.

Of Repentance is about finding the right model to follow for living your life, but it also makes a curious statement that has been borne out time and again: “Natural inclinations gain assistance and strength from education; but they are scarcely to be changed and overcome.”

Of Experience starts off by comparing reason with experience, in the pursuit of knowledge. Reason is better, but experience is what we use when reason leaves us high and dry. Then the essay moves on to complain about the system of justice that has too many laws, and the system of following legal precedent which ignores the fact that no two incidences are truly the same.

Australia trip 4

November 20th. I snorkeled twice this morning, from Taka. I had thought I would do a “discovery dive” with an instructor, the second time. In the end, though, I snorkeled. I have seen LOTS of fish. Potato cod, trumpet fish, parrot fish, clown fish, red snapper, butterflyfish, shark, giant clam, nurse shark, bannerfish. I swam with Nick, then with Matt. At the end of the cod feed, Hiro brought the feed box up so the potato cod came nearly to surface, where I could see it. Yea! Now I am sunbathing. None of us should be sunbathing, of course. Bad for the skin.

Afternoon snorkeling was shorter, the Lighthouse Bommie, south of where we were in the morning. I saw a sea turtle! It was a hawksbill turtle. First I saw it gliding along the edge of the bommie. Then I cleared my goggles, and it was beginning to rise closer to me. I saw it surface a couple of times before swimming away from me. I practiced diving while snorkeling. I’m really bad at it, but it was fun. Snorkeling here while others scuba’d, was like playing in the bathtub instead of swimming.

I saw Nemo, 2 Nemos, early on, but then they disappeared. I saw a large school of narrow, silver-white fish with narrow orange stripes along the dorsal ridge (2 or 3). I saw another large school of yellowtail fusilliers, blue fish whose yellow tails resembled less-than or greater-than signs. After we were done at Lighthouse Bommie, the guests watched the crew put the dive ladders away. We saw a young hawksbill turtle and an olive sea snake surface next to our boat. Wahoo!

Australia trip 3

Wednesday, November 17th. Today began with rain, like Monday did. We had arranged to go on a guided hike, but the tour guide was late picking us up. When he arrived, he assured us that, by the time we got to the trail head, the weather would clear. It did. Yea! We had a 3-4 hour hike in and out of the Grand Canyon in Australia’s Blue Mountains. John, with Wildframe, was a terrific tour guide. His area of study is biology, and his hobby is raising orchids, plus he takes tour groups through this canyon more than once a week. He knows about most of the plants and animals there, and is humble enough to say “I don’t know” when confronted with a new species. Truly, the difference between taking the train to the summit and hiking on our own, and using John, was that John drove us from the hostel, he shared greatly of his knowledge of the area, and he was friendly and kind.

There are several canyons that all seem to meet in the middle, and there is an area where mountains give way to table lands. We walked down below the cliffs, which were at about 3,000 feet. I don’t know how deep this Grand Canyon is, but it took us about 2 and a half hours to walk to the bottom of it, stopping frequently to ask questions and take pictures. I wish I could show a picture of one of the orange crawfish we saw. Unfortunately, I couldn’t get close enough to get a good picture. We learned the difference in the appearance of the tree fern and the king fern. We learned what iron stone is. We found out that where iron stone forms a layer between layers of sandstone, sometimes a swamp forms above, and then beautiful waterfalls appear below. We saw lots and lots of eucalyptus trees, different kinds, and we learned about how eucalyptus responds to forest fires. We saw different kinds of acacia, and also banxia. We saw parrots and cockatoos, and carrawongs, and Australian crows--which sounded just like cats.

Thursday evening, November 18th. We’re at the Cairns Central YHA, waiting for Pizza Hut to arrive with 30 pizzas. It’s $5 pizza night! Lots of hungry young men and women’s hopes for an early dinner were dashed when the receptionist announced that Pizza Hut was one hour behind schedule. 30 pizzas!

Tomorrow, at 5pm, we will leave for Cod Hole and the Coral Sea (Osprey Reef). Brad will scuba dive, and I will snorkel or laze about on the boat. We’ll be gone until Tuesday at 2:30pm, and we probably won’t have internet access. Have a lovely weekend!
