The self-healing car!

Posted by in categories: business, transportation

Watch what happens when I scratch Brent Rivera ‘s car…! It heals itself because of the SunTek Window Film Paint Protection Film it has on it. Highly recommend these guys! They use 3D scanning tech and also have the biggest film in the business which means no seam lines. Hit them up if you want your car to look like new for years and years… SunTekfilm & Envious Detailing.

The first observation of a stable torus of fluid’s resonance frequencies

Posted by in category: biotech/medical

A team of researchers at Laroche Laboratory, Université Paris Diderot and Université de Lyon has recently collected the first measurements of the resonance frequencies of a stable torus of fluid. The method they used to collect these observations, outlined in a paper published in Physical Review Letters, could enable the modeling of a variety of large-scale structures that transiently arise in vortex rings.

Vortex rings are torus-shaped vortexes that can appear in both liquids and gases in a variety of settings. In nature, there are several examples of these vortex rings, including underwater bubble rings produced by divers or dolphins, smoke rings, and blood rings in the human heart.

“Although it has been shown that the dynamics of a vortex ring are dominated by large-scale structures at its periphery, the mechanisms governing their appearance are not well understood, reflecting to a large extent the experimental difficulties in generating a stable liquid torus under well-controlled conditions,” Eric Falcon, one of the researchers who carried out the recent study, told “It is in this context that we wanted to make a fluid ring stable.”

Using an optical tweezer array of laser-cooled molecules to observe ground state collisions

Posted by in category: particle physics

A team of researchers from Harvard University and Massachusetts Institute of Technology has found that they could use an optical tweezer array of laser-cooled molecules to observe ground state collisions between individual molecules. In their paper published in the journal Science, the group describes their work with cooled calcium monofluoride molecules trapped by optical tweezers, and what they learned from their experiments. Svetlana Kotochigova, with Temple University, has published a Perspective piece in the same journal issue outlining the work—she also gives an overview of the work being done with arrays of optical tweezers to better understand molecules in general.

As Kotochigova notes, the development of optical tweezers in the 1970s has led to groundbreaking science because it allows for studying atoms and at an unprecedented level of detail. Their work involves using to create a force that can hold extremely tiny objects in place as they are being studied. In more recent times, have grown in sophistication—they can now be used to manipulate arrays of molecules, which allows researchers to see what happens when they interact under very controlled conditions. As the researchers note, such arrays are typically chilled to keep their activity at a minimum as the molecules are being studied. In this new effort, the researchers chose to study arrays of cooled calcium monofluoride molecules because they have what the team describes as nearly diagonal Franck-Condon factors, which means they can be electronically excited by firing a laser at them, and then revert to an after emission.

In their work, the researchers created arrays of by diffracting a single beam into many smaller beams, each of which could be rearranged to suit their purposes in real time. In the initial state, an unknown number of molecules were trapped in the array. The team then used light to force collisions between the molecules, pushing some of them out of the array until they had the desired number in each tweezer. They report that in instances where there were just two molecules present, they were able to observe natural ultracold collisions—allowing a clear view of the action.

Testing quantum mechanics in a non-inertial reference frame using a rotating interferometer

Posted by in categories: electronics, quantum physics

A team of researchers from the University of Glasgow and the University of Southampton has devised a novel way to test quantum mechanics in a non-inertial reference frame by using a rotating interferometer. In their paper published in the journal Physical Review Letters, the group describes studying the Hong-Ou-Mandel interference using fiber coils on a rotating disk, and what they found.

As physicists struggle with the problem of uniting and , they devise new ways to both. In this new effort, the researchers noted that the two theories are consistent under some conditions—such as when gravity is very weak, or when modest acceleration is involved. In their experiment, they chose to test the Hong-Ou-Mandel interference, in which entangled photons are sent on different paths along a circular track—one clockwise, the other counterclockwise. Theory suggests that when such entangled photons are reunited, they should bunch together and move toward one detector or the other. Conversely, non-entangled photons should travel toward either detector randomly.

In their experiment, the researchers set fiber cables on a rotating disk along with sensors for reading where the photons went after passing through the cables. They then sent a stream of entangled photons through the fiber cables (one clockwise, the other counterclockwise) and noted how they behaved as the disk was rotated—a means of applying a non-inertial reference frame. The researchers report that, as expected, the entangled photons did, indeed, bunch up and march off to a sensor together after being reunited with a beam splitter. More importantly, they noted that applying a non-inertial reference frame resulted in one of a pair of photons arriving a little later than the other, which in turn had an impact on the bunching signals the team recorded.

Healthy Life Extension / Physical Immortality – The Mass Possibility

Posted by in categories: alien life, life extension

‘Healthy Life Extension / Physical Immortality – the mass possibility ‘is presented as ’a symphony of voices’.


Throughout the ages, pioneers have been questioning the accepted belief systems of the populace, and producing major evolutionary leaps: “The Earth is the centre of the Universe” gave way to the understanding that the earth revolves around the sun. “The Earth is flat” fell away when Columbus did not fall over the edge. The Wright Brothers also flew us into another reality as have countless others. I will be suggesting in the words to follow that the belief system “physical death is inevitable” may have a similar fate.
