The 8th Day of Christmas





"This release features a composite image of a cluster of young stars looking decidedly like a cosmic Christmas tree! The cluster, known as NGC 2264, is in our Milky Way Galaxy, about 2,500 light-years from Earth. Some of the stars in the cluster are relatively small, and some are relatively large, ranging from one tenth to seven times the mass of our Sun."

The End of Physics As We Know It...?


Perhaps, things are looking up!



"The stakes now could not be higher. This summer, the LHC began its second phase of operation with an energy almost double what we achieved in the first run. What particle physicists are all desperately hoping for are signs of new particles, micro black holes, or maybe something totally unexpected emerging from the violent collisions at the Large Hadron Collider. If so, then we can continue this long journey that began 100 years ago with Albert Einstein towards an ever deeper understanding of the laws of nature.

But if, in two or three years' time, when the LHC switches off again for a second long shutdown, we've found nothing but the Higgs boson, then we may be entering a new era in physics: an era where there are weird features of the universe that we cannot explain; an era where we have hints that we live in a multiverse that lies frustratingly forever beyond our reach; an era where we will never be able to answer the question, "Why is there something rather than nothing?"

- Harry Cliff, from the TED Talk interactive transcript.

Okay, call me optimistic (or stupidly hopeful), but for a transdimensionalist, this is actually good news.

I came upon the above article earlier in the week, but, for obvious reasons (see previous 2 posts), wasn't up to posting any notice about it. Meanwhile, Paul Kimball beat me to it, and posted the TED video here.

While there isn't anything new about a physicist's inability to answer The Big Question, what is new is the admission that there might be a vastly unknowable X-Factor involved.

Might there be a ghost in the machine, after all?

We do so love a good ghost story! ;-)

Pendulum Waves and Hidden Symmetries





David Peeples sent me a view of the video (above) today - thanks, David - featuring a ball pendulum, which takes on interesting patterns when viewed from the side. Technical aspects of this "wave" effect can be found on this Harvard page.

Interestingly, the symmetries we see above are not the same ones we see below - the same variety of experiment now viewed from the front (and above) of a similar pendulum.
