Our University’s former Safety-Office-in-Chief, who retired about ten years ago, had a line in horror stories while presenting training lectures.  One of his “things” was always radiation checking a new piece of equipment before releasing it for use.

One of the disappointments experienced by most mathematics students is that they never get a course in mathematics. They get courses in calculus, algebra, topology, and so on, but the division of labor in teaching seems to prevent these different topics from being combined into a whole. In fact, some of the most important and natural questions are stifled because they fall on the wrong side of topic boundary lines. Algebraists do not discuss the fundamental theorem of algebra because “that’s analysis” and analysts do not discuss Riemann surfaces because “that’s topology,” for example.

Well, who exactly is DORIS?  “She” is actually the first Doppel-Ring-Speicher (which translates neatly into English as “Double-Ring Storage”) at DESY, the Deutsches Elektronen Synchrotron in Hamburg.  It’s not the only one; the more recent PETRA (Positron-Elektron-Tandem-Ring-Anlage) and HERA (Hadron-Elektron-Ring-Anlage) are both storage rings.  
 

Brain damage at birth is a horrible thing to happen to a baby.  Brain cells are very vulnerable to hypoxic / ischemic damage (the latter term referring to restricted blood supply), which makes birth a dangerous time.  Therefore, it was cheering to read a BBC news item

First baby given xenon gas to prevent brain injury

which led me to the Bristol University press release First newborn receives xenon gas in bid to prevent brain injury which begins

I have just returned from over a week working at DESY (das Deutsches Elektronen Synchrotron) at Hamburg, and when I am not so tired I hope to write up some more synchrotron stuff for you all.  We were working over the Easter holiday, and while the DESY Bistro provided a magnificent brunch over that four-day period, on Sunday and Monday the only place within walking distance where we could find something to eat in the evening was Burger King (very appropriate for Hamburg, don’t you think?)
