astro picture for the day

I found it!  This is not the Trantulla nebula of the large magellanic cloud(one our galaxies irregular satellite galaxy); this one is even bigger; it has to be; it's in a galaxy three million light years away!  This is a Hubble picture that I think probably will be forgotten(already has).

-----------------------------------Mechanical Universe extra for the day!

Isaac Newton's derivation of Kepler's laws from his inverse square law and his three fundamental laws of physics was one of the first such great syntheses in mathematical science.  Another would be quantum mechanics deriving all of the chemistry properties of the previous hundred years!  Another would be General Relavity making Newtonian mechanics a low speed special case.  Maxwell's deriving of previous laws of electricity and magnetism.  I've seen but would have to review that they've done such vast generalisations in thermodynamics; i think it was combining Newton's dynamical laws with thermodynamics by a Pierre Dunham. 

When new theories take in old theories as general cases, they are able to establish the old facts much more directly.  All theories are established indirectly at first(with the discovery of the sun centered solar system being the classic example), and then when Isaac Newton's come around to derive the old theorems by means of vaster generalisations, well, the old stuff is made much more systematic.

from qubits to  . . . drumroll . . . superqubits!  Supersymmetric generalisation of qubits!
