One thing I like about physics, is that I can do work anytime I like. When I'm in a bus stop freezing my butt off while waiting for the no. 113, I can keep myself occupied by thinking about problems. I think that when I'm stuck with something, actually staring at the piece of paper strewn with equations can be a hindrance rather than a help. Maybe it's something to do with a mindset...when I'm sitting right there, I'm forcing myself to solve the problem, and if it isn't obvious, I do get frustrated and angry very quickly. When I'm doing something else, the answers somehow start to seep into my brain subconsciously, or if I'm really bored, thinking about problem free-hand is surprisingly effective.

I was a bit pissed of about a derivation that I had to do for particle physics in the afternoon.... it was an integration that looked rather scary (but then, the emotion that pops up in my whenever I see long equations is fear....), and I was getting frustrated as I kept hitting a brick wall. Part of the frustration was a bit more general, as I reflected on my inferior mathematical ability. I decided to go grocery shopping and get an early dinner...while I was walking along in the shopping centre, and steps to get the integration seemed to flow into my head without thinking.

After I came back, I sat down and did the derivation in 5 minutes flat (OK, I got the wrong sign, but I'm not going to be too fussy...). The human brain works in mysterious ways....

Some of you might know that I was in Paris for a conference last week. It was the UNESCO's launch of the World Year of Physics, 2005, to commemorate Einstein's miracle year in 1905 when he wrote 3 papers that changed the world. Unfortunately, my New Year's resolution is to become a workaholic, so I can't spare the time to write in detail.

However, here's a report that I wrote to the Institute of Physics student newsletter to whet your appetites:

It was appropriate that the launch conference for the United Nations World Year of Physics was held virtually in the shadow of the Eiffel Tower in Paris, France. Constructed in 1889, the Eiffel Tower embodied the anticipated scientific and technological advancements of the coming 20^th century. In 1905, this spirit was turned into reality by an unknown Swiss patent clerk in Bern, doing theoretical physics in his spare time.

A hundred years later, the global physics community and the UN have decided to recognise 2005 as the World Year of Physics (WYP) in homage to Albert Einstein’s annus mirabilis. Jointly organised by UNESCO and the European Physical Society, the launch conference for WYP 2005 was held at the UNESCO headquarters located several blocks from the Eiffel Tower. Nearly 1300 delegates from all over the world were gathered for this event, which was held from 13-15 January. In view of Einstein’s youth when he published his seminal papers, it was fitting that half of the delegates were students at various levels, from high school to post-graduate studies.

The conference consisted of a non-stop schedule of talks and discussion sessions held over the three days. In following with the broad theme of ‘Physics for Tomorrow’ chosen for WYP 2005, the talks addressed of the challenges facing physicists in the 21^st century. These were presented by a distinguished panel of speakers composed largely of research physicists, including several Nobel laureates. They presented a fascinating mosaic of the unanswered questions and possibilities open to the physicist of the near future, when research will become increasingly cross-disciplinary and the boundary between fields will blur. However, the future challenges for physics extend well beyond the merely scientific.

Several of the talks and discussion sessions talked about physics in its context of its socio-economic challenges. And these are massive challenges: the increasing disparity between developed and developing countries, declining levels in the public understanding and support of science, difficulties in recruiting young people into physics, and others. The diversity of the delegates ensured that there were representative points of view from across different genders, nationalities, faiths and age groups.

As an aside from the formal sessions, there was a book exposition from various scientific publishers and a very popular showcase of interesting table-top experiments organised by a group of Danish physicists. Of course, there was the opportunity to meet other physicists and students from all over the globe, from countries as far flung as the United States and Ghana. Language was but an easily surmountable barrier in the presence of the uniting passion towards physics and science in everyone. The conference culminated in a formal banquet at the French Senate in the Palais du Luxembourg on the evening of the 14^th.

The general mood at the conference was one of optimism. Maybe it was due to the energy of the younger delegates, but there was a sense of eagerness to take on the challenges that lie ahead, and overcome them. A century ago, a 26 year-old young man profoundly changed the face of his world. His modern-day counterparts are now preparing themselves to do the same.
