Practical Physics

Downtown had its head in the clouds, it rained pretty much all day: time for LEGO. Instead of relying solely on a solid state gyroscope, I wanted to develop a better intuitive grasp of the physics involved. So, I built a test rig with an actual spinning flywheel. It flew apart, leaving my electronic robot… Continue reading Practical Physics

No Lines

As usual our Sunday morning walk took us across Boom Island. Workers were busy tearing down after a two-day music festival, the Basilica Block Party. There was visual evidence this had been a large event.

Concrete Calm

Cycled through this calm place on my random steamy ride. Industrial areas like this one in St. Paul are best explored on weekends, away from the hustle of weekday truck traffic.

Sixty Shades of Green

We’re saving this lone ripe tomato from our balcony plant for a ceremonial tasting at dinner. About sixty others are still green. We did this mostly for fun; we also have herbs in pots, which are far more practical all summer.

School’s Out

After last night’s imagined English Language Learning classroom, I stepped into a real one today for the final day of summer school. School starts again early September when I’ll continue working with the same teacher. I enjoy working with her: she prepares thoroughly, she uses my time well, and the students love her.

Exploring Who We Are

Tonight at the Guthrie: English, set entirely in an English Language Learning classroom in Tehran. I couldn’t help comparing with my own experience–the teacher was overcorrecting and there was a level of emotional intensity I’d be uncomfortable with in a classroom–but that was missing the point. Ultimately it was about identity, and that felt authentic.

DQ, Practically Breakfast

10:00 a.m. A leisurely catch-up with friends over ice cream. I usually go cycling with one of them, but he’d broken his fibula in a bicycle accident and is getting a plate inserted on Thursday. DQ offered a flat, accessible path from the car to our outdoor table. His wife also broke a bone earlier… Continue reading DQ, Practically Breakfast

Balancing Act

Built a self-balancing two-wheeled robot, a copy of a design I found on the Internet. It wanders around autonomously ‘seeing’ with an ultrasonic sensor and maintaining balance using a gyro sensor. After about ten minutes the robot suddenly accelerates and falls over, hence the carpet. I need to slow down and understand the algorithm from… Continue reading Balancing Act

Fast-Forward to Fireworks

Aquatennial fireworks from our balcony capped off an evening of Olympic action. We’ve splashed out $15 for NBC’s (proud as a…) Peacock service for commercial-free on-demand access to every event. Paris is 7 hours ahead, so we can fast-forward through the boring bits.
