I’ve been mulling over this topic for a while, but a pair of blog posts this week has finally prompted me to write about it. One of them, entitled “Why I won’t be studying physics at A-level” appeared yesterday in the education section of the Guardian newspaper. In it, the anonymous female author lists a number of reasons why she is leaving physics, including a lack of female teachers and an “uninspiring” GCSE physics syllabus that “seemed out of touch compared with the stem cells and glucoregulation we were studying in biology”. There’s plenty to debate there already, but to me, the following paragraph was the most striking:
“I don’t dislike physics; neither do I find it boring or particularly difficult. But I do enjoy my other subjects more, so when it came to choosing between physics and geography for my fourth AS-level I opted for the latter. I thought it would be good to take a humanities subject to balance out the sciences.”

Most of us want everything in life right here, right now. From fast food to fast cars, none of us can be bothered to hang about any longer than absolutely necessary. Where’s your reply to my e-mail I sent five minutes ago? Why haven’t you responded to my Tweet? Do you really expect me to read that 500-page novel for fun?
It was perhaps as an antidote to the ever-faster pace of life that so much has been made of two physics experiments that recently produced new data for the first time in years. I’m talking, of course, about the “pitch-drop” experiments at Trinity College Dublin in Ireland and the University of Queensland, Australia, which both consist of a glass funnel of sticky tar-like substance. A drop from the Trinity experiment finally fell last July, with a video of the event quickly going viral, while the Queensland set-up dripped this April for the first time in 13 years. (For more on why both experiments proved so popular, check out our great feature by Shane D Bergin, Stefan Hutzler and Denis Weaire from Trinity.)
But if you can’t be bothered to hang around for 10 years or more, you’ll be pleased to hear that physicists at Queen Mary University of London – led by Kostya Trachenko – have now set up a new pitch-drop experiment to explore the difference between solid and liquids on the much shorter timescale of just a few months.

In case you haven’t seen it yet, I do encourage you to read our feature article from the May issue of Physics World about the now-famous pitch-drop experiment at Trinity College Dublin. This simple funnel of pitch shot to fame last year after a drop from it was finally observed falling for the first time – with a video of the dripping drop having so far been viewed more than two million times on YouTube.
Although it was the first time that a drop had been seen to drip from the Dublin funnel, it’s thought that other drops would have fallen about once a decade since the apparatus was set up in 1944. Be that as it may, Trevor Cawthorne from Queen Elizabeth’s Grammar School in Horncastle, Lincolnshire, UK, e-mailed me this morning, pointing out – quite rightly – that “10 years is a long time to wait for the results of an experiment”.

Having flown almost half-way round the world from Bristol to Rio, you might think there is little in common between Physics World‘s home city and the Brazilian metropolis.
But on my trip to the Brazilian Centre for Physics Research (CBPF) in Rio today, it soon became clear from the statistical physicist Constantino Tsallis, who hosted my visit, that there is indeed a link between the two cities. That connection lies with the Brazilian physicist César Lattes, who was the founding director of the CBPF.
