Scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) in Berlin combined state-of-the-art experiments and to test a fundamental assumption underlying strong-field physics. Their results refine our understanding of strong-field processes such as high harmonic generation (HHG) and laser-induced electron diffraction (LIED).

Strong can extract an electron from a molecule (ionization), accelerate it away into free space, then turn it around (propagation), and finally collide it with the molecule (recollision). This is the widely used three-step model of strong-field physics. In the recollision step, the electron may, for example, recombine with the parent ion, giving rise to high harmonic generation, or scatter elastically, giving rise to laser-induced electron diffraction.

One of the commonly used assumptions underlying attosecond is that, in the propagation step, the initial structure of the ionized electron is “washed out”, thus losing the information on the originating orbital. So far, this assumption was not experimentally verified in molecular systems.

The scene in a normally quiet neighborhood on Hawaii’s Big Island is like something out of an overwrought disaster movie: volcanic fissures have opened up, spraying smoke and hot lava in the air where just last week there was a road and people’s backyards.

On Friday morning, Hawaii County Mayor Harry Kim told reporters that two homes have been destroyed by the lava.

Eruptions began in the rift zone to the east of the Kilauea volcano Thursday, prompting evacuations of the Leilani Estates and Lanipuna Gardens subdivisions in Puna on the island’s southeastern corner.

A new study published by researchers at Western University and Lawson Health Research Institute has shown a link between the gut microbiome and atherosclerosis.

During the study, the team examined blood levels of metabolic products in the gut microbiomes of 316 people from three groups: those with regular levels of plaque for their age, those who had low levels of plaque despite being at high risk, and those who had unusually high levels of plaque.

They discovered that in the patients with unusually high levels of plaque, there were significantly higher blood levels of harmful metabolic products. Specifically, these were the metabolites TMAO, p-cresyl sulfate, p-cresyl glucuronide, and phenylacetylglutamine, which are created by gut bacteria. They also assessed the development of plaques in the arteries via carotid ultrasound.

Ironically, my more popular posts are ones furthest from my passion and core interests. They are larks—never intended to go viral. This is about one of them…

Apart from family, I typically steer clear of religious topics. I identify with a mainstream religion, but it is completely beside the purpose of Lifeboat Foundation, and it is a personal affair.[1]

Yet, here we discuss a religious topic, after all. Let’s get started…

Question

Do atheists agree that the fact that we can’t understand
quantum physics is at least somewhat evidence of Allah?

An Objective Answer

Do you assert that a failure to understand something is evidence of God?

I don’t fully understand a triple-Lutz (ice skating) or the Jessica stitch (needlepoint)—and I certainly don’t get why an electric dryer leaves moisture on light weight linens, when a gas dryer gets them bone-dry before the plush towels.

Is my inability to solve these mysteries evidence of Allah (or Yahweh, haShem or Y’Shewa)? Of course, not! It has nothing to do with God or religion. The fact that I don’t quite grasp every complex task or unexplained science is not evidence of God, it is evidence of my own ignorance.

On the other hand, I am fortunate to understand quantum physics—both academically and from an innate perspective. That is, behavior of waves and matter on a subatomic scale make perfect sense to me.

You would be correct to point out that certain quantum behavior seems to violate common sense:

Earthquakes continue to shake the east side of the Big Island and at 10:30 a.m. on Thursday, May 3, 2018, a 4.6-magnitude earthquake struck the Volcano area of the island.

The Pacific Tsunami Warning Center reported that the earthquake was not large enough to cause a tsunami for the island of Hawai’i.

Preliminary data indicates that the earthquake measuring a magnitude of 4.6 was centered in the vicinity of the south flank of Kīlauea Volcano.

New research from North Carolina State University and the University of Colorado Boulder finds that steep declines in the use of coal for power generation over the past decade were caused largely by less expensive natural gas and the availability of wind energy – not by environmental regulations.

“From 2008 to 2013, coal dropped from about 50 percent of U.S. to around 30 percent,” says Harrison Fell, an associate professor of resource economics at NC State and co-lead author of a paper on the work.

“Coal boosters blamed stiffer regulations, calling it a ‘war on coal.’ But that same time period saw a steep drop in the cost of natural gas and an increase in wind . We wanted to know how big a role each of these factors played in driving down the demand for coal.”

A membrane made up of block polymers has the customizable and uniform pore sizes needed for filtering or recovering particular substances from wastewater, researchers say in a review published in npj Clean Water.

Some parts of the world have an increasing need to generate drinkable water from wastewater due to excessive chemical discharge into typical water sources or lack of rainfall. Researchers from Purdue University and the University of Notre Dame believe that a block membrane could not only improve desalination and filtration of wastewater, but could also be used in forthcoming hybrid water treatment processes that simultaneously recover substances for other purposes.

“Current nanofiltration membranes used for desalination tend to separate things based on size and electrostatic interactions, but not chemical identity,” said Bryan Boudouris, Purdue’s Robert and Sally Weist Associate Professor of Chemical Engineering. “If we tailor the right membrane to the right application to begin with, then less energy is used.”

NASA’s next Red Planet explorer has arrived at Vandenberg Air Force Base in California — a big step forward in the countdown to T-zero. The spacecraft is called InSight — short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport — and it’s being tested, fueled and encapsulated for launch aboard the powerful United Launch Alliance Atlas V rocket. The upcoming liftoff will mark the first time an interplanetary mission has launched from the West Coast.
