Hi everyone! Sorry that this week’s entry is a little late; work was rough this week. I had a problem set (we just call them sets for short) due for a class called EE114 on Monday. EE114 is an analog circuit design class (you can find the course description here ). It’s taught by that wonderful man on the right side of the page, Dr. Ali Hajimiri. Professor Hajimiri is easily one of the best professors I have had at Caltech, and as you would expect his class is very well taught. Unfortunately, his class is also very difficult. Last weekend, our class’s problem set was worse than usual. Due to my other responsibilities and time spent avoiding them, I didn’t really get to start on the set until Sunday at about noon. I finished the set on Monday at 4:30pm (30 minutes before the due time). In that 28 hour period, I got less than an hour of sleep and was able to eat about two meals. That sounds really bad, but there is a positive side. For one, I wasn’t alone–we had something like ten to fifteen students working on this set together in Sherman Fairchild Library, and there’s some sort of bonding experience that accompanies a grueling set like this one. I still remember our collective groans as the sun began to peek through the library windows, with the end of our sets nowhere in sight. Another positive was that the set was reasonably interesting and challenging; it wasn’t mindless grunge work. Even knowing this, you might still wonder why I do it.
