In Chemistry, Physics, Space & Astronomy, Weekly Roundup

Cuddly quarks

Maybe I’m just a big nerdy kid, but it seems I just can’t resist plush versions of scientific concepts. Earlier this year we had internal organs, and now this week I came across The Particle Zoo. It’s all your friends from the standard model of physics, and more! My favourite has to be the incredibly devious looking tachyon:

Time for a new table?

The periodic table has been in use for nearly 150 years, ever since its invention by Dmitri Mendeleev in 1869. Is it time for chemists to rearrange the furniture and bring in something a little more…round? Mohd Abubakr of Microsoft India seems to think so, and presents his own version:

The circular periodic table
The circular periodic table

One advantage is that the 7 rings represent the 7 electron shells of an atom. Another is that the elements get larger as you move out from the center. As the Physics arXiv blog points out though, it’s hard to read a circular table without rotating it – which unlike the regular table, doesn’t make for a great wall poster!

Obama, the astronomical President

Colin provided me with this final roundup item, so I’ll hand over to him:

What a week it has been for President Barack Obama. On Friday morning he was woken up at 6am by his aides who broke the news that he had (rather controversially) won this year’s Nobel Peace Prize.

With such news his diary commitments on Wednesday evening have largely been overlooked. Yet on that evening he and 150 local school children took to the South Lawn for Astronomy Night at The Whitehouse with guests including the second man on the Moon, Buzz Aldrin.

But what really captured the imagination was his opening speech. It was a rallying cry for a change in education, an eloquent rendition of just why science matters and a piece of science communication par excellence. Take a look for yourself:


  1. One Comment

  2. We have the entire collection of the particle zoo here at the CERN press office – they’re awesome! They’re also weighted according to mass which is kinda cool – so the beauty (bottom) quark weighs more than the strange quark which weighs more than the down quark :)
