With the discovery of sound waves in the CMB, we have
entered a new era of precision cosmology in which we can begin to talk
with certainty about the origin of structure and the content of matter
and energy in the universe–Wayne Hu
I quoted myself below with regard to Matt Strassler’s two articles, because it is of interest to me to say how we might make use of the matters around us. As well, too point out the Layman I am. I appreciate what is being put out there in terms of the science so as to help one progress in their own studies.
Yes most interesting for sure.
Orbitals integration….most important.
Just a few points for consideration in terms of the energy valuations in terms of the Matter construct as energy configurations….right from molecules to proton nucleus(powers of ten). Bohr’s Model
As well Seaborg’s contributions, as a precursor to elemental table construction. Quite early, Law of Octaves looking at the historical perspective.
As a Law of Octave(historically), this also makes for some interesting comparisons in my mind to a string theorist’s mind, as a particle interpretation energy valuation description, or, would that be an unfair comparison?? Another way perhaps, in which to perceive the “Pythagorean sound” as weight with water suspended in gourds while plucking strings?:)
In this sense I am speaking in terms of the history of the way on which a mind can perceive being open too, as to what it is we select to form the realities around us. These are constructive ways in which we may apply a schematic drawing and building up of, to form the structure of the reality as it is measure and perceived by us. In his answer, Matt openly addresses the “tent model” by one of his commentators. and says,”Your tent fabric analogy is an interesting one.”
This is part of who I am as to my inquiring into the diverse nature of our measures, which help to develop the perspective around the elements and how we make use of them. Why I may look to astrophysical sources to help me point toward the reductionist versions of the data we are gaining from measures. Which helps ascertain the aspects of the reality building we are doing.
Also too, I have revealed my own bias to “the sound” as a sensory revelation of sorts. How one may say measure is of this reality, and is spoken too. In this sense while their is a whole pluralistic need for mathematical ascertains to say one is a string theorist, I would say on a most fundamental level without such structure around me, I may be interpreted “as ignorant” while suggesting the garb and cloak I wear is based on this theatrical disguise.
For consideration by Lumo perhaps then?:)
Now, Aidan says that the electron is not spinning because it’s
pointlike. Even if we adopt the usual definitions that were developed in
the classical framework, this statement by Aidan is wrong at both
levels. First, it’s not true that the electron is strictly point-like.
Before the Planck scale, all particles have to have an internal
structure because quantum gravity doesn’t allow distances shorter than
the Planck length to be resolved. The internal architecture of particles
therefore can’t be “strictly and sharply point-like”. In all
perturbative string vacua, the electrons are vibrating strings
(occupying space comparable to the string length, a few orders of
magnitude longer than the Planck length) and indeed, the spin may be
understood as coming from some internal degrees of freedom that are
localized at an extended object.
In fact, the stringy picture of the spin tells us exactly where the
reasoning that pointlike or tiny objects can’t carry a nonzero or rather
large angular momentum breaks down. The string is locally a very heavy
object – the tension or the linear mass density of the fundamental
string in string theory is huge – and the motion of this string just a
string length away from the center of mass has a big,
Planck’s-constant-sized impact on the angular momentum. On the other
hand, the overall rest mass of the resulting particle may be small or
even zero because of various cancellations, including the fact that the
sum of integers is equal to
which is the primary identity guaranteeing that some stringy vibration
modes remain exactly massless (and others’ masses only arise from some
much smaller corrections).The electron is spinning, after all
But yes, I gaze star-ward as well, as to include in my vision of the reality around us a fundamental make-up requirement, so as to say, the LHC is a corresponding feature of the reality coordination as a microscopic understanding of a macroscopic world.
The last major changes to the periodic table was done in
the middle of the 20th Century. Glenn Seaborg is given the credit for
it. Starting with his discovery of plutonium in 1940, he discovered all
the transuranic elements from 94 to 102. He reconfigured the periodic
table by placing the actinide series below the lanthanide series. In
1951, Seaborg was awarded the Noble prize in chemistry for his work.
Element 106 has been named seaborgium (Sg) in his honor.A BRIEF HISTORY OF THE DEVELOPMENT OF PERIODIC TABLE
