I’d been swimming in a luxurious, long, deep pool in the San Fernando Valley at. 83° by a thermometer in the water while 100°+ in the air.

Sitting in the Sun, feet dangling in the water, I could see the light’s refracted patterns (Snell’s law) from it’s surface along the bottom of the pool.

I’d seen video documentary mock-ups to show how existence “looks” at or near the Planck Scale. Yet here and now was an example even clearer.

Envisioning part of the pool bottom as a slice of “quantum” space, filaments fleeted into existence, each having been created by that gone before and out of them. And bits of brightness, (again, reflections of the Sun along the surface, cast on the bottom and sides) would move along the length of each segment, intersecting with their ends, such “strings” quickly dissipating here, and reappearing there with each such interaction.

Moreover, from my calves and feet, there would enter waves of interference that would yield to the “strings” an even greater sense of overall excitation. This too might be seen as a representation of the “Uncertainty Principle” where at the quantum level, “virtual” entities come into and go out of existence, yet perhaps summing to an “actualization” of reality, which however even billions of years hence, may as likely decay and zap back into the void from whence they came.

And I’d bet too that this could all be worked out mathematically.

But, as I said, it’s merely a representation of such conditions, which is all that can ever be achieved at the Planck Scale anyway. So as this lazy day’s imaginings gave rise to other waxings, into the water I went, even in that second of submergence, to childhood again.

Is dark energy lurking in hidden spatial dimensions?

[snip] To get the same amount of acceleration seen by astronomers, Greene and Levin calculate that the extra dimensions should have a scale of about 0.01 millimetre. Dark energy would be hiding less than a hair’s breadth away... Eric Adelberger and his team at the University of Washington in Seattle, US, have run a series of experiments using a twisting pendulum to measure the short-range strength of gravity, and they have already ruled out extra dimensions larger than a 0.1 millimetre.

In an effort to further cement their dominance, Google has introduce two new refinements to its search engine as of March 24, 2009.London - Google's search engine is already the dominant player in the internet query business, with over 70% of all search engine hits beginning there, according to seoconsultants.com. In an effort to further cement their dominance, Google has introduce two new refinements to its search engine as of March 24, 2009. Both of these improvements are related to the use of searches with longer strings of keywords.

Google has now added a "searches relate to:" selection at the bottom of a search's results page. These are, in effect, searches that relate keywords in a query to completely different keywords that have a semantic connection. For example, a search for "physics theories" will return a suggestion to search for "string theory," "quantum mechanics," and "newton's laws."

The second improvement is the addition of longer snippets from each website returned by a query. These text descriptions have any and all keywords highlighted, so that a searcher can more quickly determine if a given website does indeed contain that for which they're looking. The longer the search query, the more context Google will return for each site found.

Both of these improvements should help Google retain its dominance in the internet search engine field.

Hi — I’ve just gone through all the ping lists (just finished that process) to clean out the ex-FReepers. In that connection, I’ve removed you from the String Theory ping list.
