Another semester

It's been a while since my last update, and I promise to get to blogging more. Another semester has gone by, though for me it doesn't make a difference as I don't have any classes to take. I did get a lot accomplished this term in the lab though. I'm not close to finishing, but I feel like I made significant progress and I'm very happy about that. I have been able to complete a low noise cryogenic single stage self-biased high frequency amplifier with 18 dB of gain, and am in the process of building a two stage device. Might not sound particularly difficult for those who have been in the microwave business for a while, but for the last two months this was all that I have been working on. It does feel good though to now be able to say I understand what's going on, and more importantly, that I've made a working, functional device. The amplifier certainly feels like my first real accomplishment in the lab, since I essentially put everything together, with everyone's help and guidance.

More picture updates to come as I get to taking more pictures!

Goodbyes

It's hard saying goodbye. A good friend of mine is leaving Duke to return to Paris. He was fed up with the physics program here, and after securing a position in France, decided to return home. It's unfortunate that the department here could not do more to help, as he was genuinely bright; unfortunately he was suffering from depression, probably induced by the stresses of the PhD program as well as the dull boring city of Durham. In general how does one say goodbye? You don't really, especially if you're good friends. You just end up saying hello less often. At least that's my take. Unfortunately, more on goodbyes, it's goodbye to Duke's NCAA hopes for this year. We were outplayed by LSU. Sure the refs were really not entirely fair (from our point of view of course), but they closed our top scorer down. It was a fun run, and I enjoyed watching them play, especially since I thought they played such great team basketball, but it's over. Such a somber posti...

FAO Schwarz!

Found this on Funny Times: What New Toys Did You Get? (compiled by Phil Proctor) Capitalism: He who dies with the most toys, wins. Hari Krishna: He who plays with the most toys, wins. Judaism: He who buys toys at the lowest price, wins. Catholicism: He who denis himself the most toys, wins. Anglican: They were our toys first. Greek Orthodox: No, they were ours first.

John Bardeen

I'm reading the biography of John Bardeen, co-inventor of the transistor and co-author of the BCS theory of superconductivity. He won a Nobel Prize in Physics for each of these discoveries, making him the only person ever to win two Nobels in the same category. The book is "True Genius---The Life and Science of John Bardeen" by Hoddeson and Daitch. He's not as well known to the public as Einstein or Feynman, but his contributions to science are up there with the greats. Here's a quote that I find very wise, from a man not known for saying much. People have said about Bardeen, "he doesn't say much, but when he does say something, you pay attention." "I feel that science cannot provide an answer to the ultimate questions about the meaning and purpose of life. With religion, one can get answers on faith. Most scientists leave them open and perhaps unanswerable, but do abide by a code of moral values. For civilized society to succeed, there must be ...
