Quantum Foam and Discrete Measures

Physicists would dearly love to study this foam but there’s a
problem. Spacetime only becomes foam-like on the tiniest scale, at
so-called Planck lengths of 10^-35 metres or so. See: How to Measure Quantum Foam With a Tabletop Experiment

An ongoing question was raised by Bee of Backreaction and thoughts I have had as to the applicability of it’s experimental design.

 

 

It’s difficult to see that while seeing the larger view of a Lagrangian of the universe is to see such an experiment located “as part and parcel of the variance in determination of the strength and weaknesses of that Lagrangian.” So you drive the focus down to the microscopic, and then to ask, in what case has the photon‘s journey been of value in the ascertaining the distance and time, of that photon’s journey? Just trying to orientate perspective in the case of Lagrange,  yet we see on the macroscopic that it works.

It is to orientate the thought experiment in the direction of a determination of value when  assigned to Lagrangian and its limits at minimal length. A phenomenological question then about that environment with this application.

 

 

On another note then being respective of the drive toward understanding using  Higg’s,”The solution is to make the equations more complicated and introduce a
Higgs field, which, once it is non-zero on average, can give the electron its mass without messing up the workings of the weak nuclear force

1.Why the Higgs Field is Necessary

It is difficult then to ascertain Higgs field at zero, yet I want to count?

Abell 399 and Abell 401, connected by a bridge of hot gas

This image shows galaxy clusters Abell 399, lower center, and Abell 401
connected by a bridge of hot gas (ESA Planck Collaboration / STScI
Digitized Sky Survey)

 Planck’s primary task is to capture the most ancient light of the
cosmos. If this faint light interacts with the hot gas permeating
different types of space structures including galaxies and galaxy
clusters, its energy distribution is modified in a characteristic way, a
phenomenon known as the Sunyaev-Zel’dovich (SZ) effect.

NASA’s newest observatory, the Gamma-ray Large Area Space Telescope, or GLAST, has begun its mission of exploring the universe in high-energy gamma rays. The spacecraft and its revolutionary instruments passed their orbital checkout with flying colors.

NASA announced August 26 that GLAST has been renamed the Fermi Gamma-ray Space Telescope. The new name honors Prof. Enrico Fermi (1901-1954), a pioneer in high-energy physics.

Olfactory Experience

 

If you sprinkle fine sand uniformly over a drumhead and then make it vibrate, the grains of sand will collect in characteristic spots and figures, called Chladni patterns. These patterns reveal much information about the size and the shape of the drum and the elasticity of its membrane. In particular, the distribution of spots depends not only on the way the drum vibrated initially but also on the global shape of the drum, because the waves will be reflected differently according to whether the edge of the drumhead is a circle, an ellipse, a square, or some other shape.

In cosmology, the early Universe was crossed by real acoustic waves generated soon after Big Bang. Such vibrations left their imprints 300 000 years later as tiny density fluctuations in the primordial plasma. Hot and cold spots in the present-day 2.7 K CMB radiation reveal those density fluctuations. Thus the CMB temperature fluctuations look like Chaldni patterns resulting from a complicated three-dimensional drumhead that

How we make use of our senses? Does one not wonder about the effect of our memory retention how on how well we can call up memories?

The Vibration theory of smell proposes that a molecule’s smell character is due to its vibrational frequency in the infrared range. The theory is opposed to the more widely accepted shape theory of olfaction, which proposes that a molecule’s smell character is due to its shape.

I expose myself to a bias in my thinking that seems natural to me with regard to the subject of vibratory reductionism. So the idea of Vibration theory of olfaction is interesting in the sense that we may use a ancient part of our physiological makeup to access memories, that are correlated with this sense as a marker.

 The Shape theory of smell states that a molecule’s particular smell is due to a ‘lock and key’ mechanism by which a scent molecule fits into olfactory receptors in the nasal epithelium.

Would we say that this is a more potent way of remembrance that we may have underestimated the nature and the way that memory induction employed not just in terms of this neurological connection of the time there in association, but as a feature of the biological presences that we muster as matter beings.

That the spectrum of sight is much finer then the matter states of consideration in terms of a waffling of a breeze that carries the scent of let’s say mom’s apple pie? So we see this impression is made not only in the retention of the memory, but is further compacted, with this “emotional significant association.”

This “emotional impact”  is significant? Not just in the smell, but of the vibratory experience we correlate with let’s say music here, so as to retain and impress upon our youth and vigor,  the choices made then.

So memory is vital in the sense that olfactory experience is important in the retention of these memories. Thus to an understanding and constructive creative schematic of defining our experiences in terms of how well such “other sense are used” to impress upon and recount experience.

Big Ideas presents Seth Lloyd of the Massachusetts Institute for Technology on Quantum Life, how organisms have evolved to make use of quantum effects.

Observational Gravitational-Wave Astronomy.

Observational Gravitational-Wave Astronomy.

Figure 1: Gravitational wave strain and strain sensitivity for a 5 year observation with PTAs. The red dashed line is the approximate strain sensitivity for current PTAs (11), and the green dashed line shows the previous estimate for the stochastic signal strength that is currently in standard use for PTA analyses (13, 14). The dark blue solid line corresponds to our mean estimate for the stochastic signal strength, with the blue shaded region bound by thin solid blue lines showing our 95% confidence interval for this estimate, based on the observational uncertainties of our model parameters. The light blue (△ACD) and cyan (△ABE) shaded regions show the area corresponding to the square root of the 2 integrand, to be integrated over logarithmic frequency intervals as in Eq. (3), for our expected SNR of 8, and the SNR of 2 expected from previous estimates (13, 14), respectively.

TEDxCambridge – Jeff Lieberman on science and spirituality

Jeff Lieberman, an MIT-trained artist, scientist and engineer, makes a scientific argument for mystical experience. He asks us to challenge our perception of what we are, our relationship to the universe, and our relationship to one another. Our minds are “thought-generating machines.” What we would happen if we could turn off the machine? If we could transcend our individual experience of the world?
