Where is that plane going? A shortcut for plane-spotters

A friend of mine has a curious habit: whenever she sees a plane in the sky, she immediately checks Flightradar24 to find out where it’s headed and where it came from. It turns out (perhaps unsurprisingly for those in the industry) all sorts of things happen in the sky. There are hot-air balloons for tourists, law enforcement aircraft, pilots in training, commercial flights, military planes… and somehow, all of them are tracked on Flightradar24.

About two years ago I bought an AirTag. I usually go days without driving, so I end up not being sure about where my car is parked. The AirTag is a simple solution for this: I left it in my glovebox and now I can check my car’s location, almost live, in my phone.

I started using a Mac back in 2018. My computer, an fairly standard HP laptop I’d bought back in 2013, was beginning to become a source of troubles. The charger wouldn’t charge, the keyboard wouldn’t hold the keys in place, and generally the computer wouldn’t compute. This was a problem, given that I was a destitute student. To my surprise, older MacBooks (the white poylycarbonate MacBooks made back in 2010) where dirt cheap, even when bought from overseas and thus with shipping and custom costs included in the price. I bought one for about 130€. It lacked the Euro (€) key and I couldn’t type words containing an ñ directly, but it felt like a small inconvenience and I quickly found workarounds. That little laptop proved hardy and powerful enough for my daily tasks, and it carried me through a computational physics course during which the rubber in the bottom peeled due to the excessive heat emanating from its dying processor. It was a pretty nice machine.
PAULA: Protein Analysis Using a Least-squares Approach

Last year, I took a physical chemistry class which had to do with the behaviour and analysis of biomolecules (mainly proteins and nucleic acids). It was fun to step outside of my comfort zone and being in a chemistry lab again, and I had a great deal of fun learning about bio-stuff again. The course worked by alternating theory classes (where we learned the formal aspects of the techniques we would later apply) and lab sessions. We were given a small sample of the problem molecule which we wanted to characterise over a period of two-or-so months, which in this case was hen egg-white lysozyme, a cheap and common protein. One goal was to pass polarised ultraviolet light through a sample of this protein, and measure how well the protein is able to twist the plane of the incident light rays. This technique is called far-ultraviolet circular dychroism, and it turns out that learning about the way a protein interacts with these particular wavelengths in this very particular sense yields a great deal of information about its structure!
