First encounter with an 88-foot loon

Rode the LRT to St. Paul’s Midway neighborhood, then walked to get a haircut. Along the way, encountered a loon (our state bird) with an 88-foot wingspan in front of the Minnesota United soccer stadium. This was unexpected. I learned it was designed by an artist from Scotland, a country devoid of loons.

By the dawn’s early light, self-evident truths

Looked up at these simple truths as I waited this morning for the bus to a school where immigrants, regardless of their legal status, are highly motivated to learn. In my first class, I worked with learners preparing to become certified nursing assistants, addressing a critical need in Minnesota.

Snowbird prep: keeping houseplants happy

The outside temperature this morning was -18°F, meaning another day indoors. Made use of the exercise room and daydreamed about our upcoming six-week trip to a warmer climate. Our large deionized water tank won’t be enough, so I connected a second tank–usually reserved for outdoor plants on the balcony–to our system. A pump transfers water from the smaller tank to the larger one.

A day off from the world

It was a day for isolating ourselves from the world: the weather was still too frigid to go outside, plus we declared a no-news day. I prototyped a LEGO pneumatic AND gate that functions significantly better than the gates I built yesterday. However, I won’t be building a pneumatic adder any time soon because I don’t have enough pistons.

Stalled by joint play in a LEGO mechanical computer

All logic functions can be constructed using AND and NOT logic gates. Modern smartphones contain billions of logic gates. However, the LEGO machine I constructed today only has four AND and four NOT gates to perform binary addition on two single-bit binary numbers. As the signal propagates from the inputs on the left to the outputs on the right, the cumulative effect of joint play leads to unreliable output movements. I need to redesign the machine.

A winter’s night with Nordic composers

Drove from heated garage to heated garage for a Minnesota Orchestra concert of music by Nordic composers. There were nods to hygge, which was fitting with temperatures staying in negative territory for a few days. We’re not leaving our building again until Wednesday.

Getting my shots

It was almost balmy weather for January in Minnesota (in the thirties) as I walked to the University for a consultation and medication top-ups (injections). With temperatures expected to drop below zero for the next few days, I’m anticipating a period of hibernation. This appointment was therefore well timed.

Saving a classroom plant

Over tonkotsu ramen, Dwight and I compared notes about our day–he in the greenhouse, me in the classroom. I showed him photos of a sad-looking plant in the classroom. He suspected overwatering and advised deionized water would be better than tap. He also suggested the plant needed to climb and might benefit from fertilizer after its dormant period. I’d previously used Google Lens on the plant, and it had led to similar advice.

Tonight: The Heart Sellers at the Guthrie

Walked over to the Guthrie to see The Heart Sellers, a play that plays on the title of the 1965 Hart-Celler Act. This landmark legislation opened up immigration to non-Europeans and gave priority to immigrants with STEM skills. In the bittersweet play, set on Thanksgiving 1973, two immigrant women, one Filipino and the other Korean, yearn for a sense of belonging.
