Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Default Re: Jellyfish Lasers Are Revolutionizing Quantum Physics

So, what will the name be, a Jel laser? Here's more:


New Kind of laser created from jellyfish proteins - http://www.affairscloud.com/new-kind...yfish-proteins

By Current Affairs Team - August 22, 2016

For the first time scientists have developed laser from fluorescent jellyfish proteins that were grown in bacteria. These lasers have the potential to be far more efficient and compact than conventional ones and could open up research avenues in quantum physics and optical computing, researchers said. The breakthrough represents a major advance in so-called polariton lasers.

Gather turned to an unusual solution:

Barrel-shaped fluorescent proteins engineered from jellyfish DNA. Each protein’s cylindrical shell encloses a component that emits light, and keeps those molecules from getting too cozy and interfering with one another.

To build their laser, Gather and his colleagues sandwiched a thin film of the fluorescent protein between two mirrors. Activating the light-emitting molecules with a pulse of blue light from an external laser successfully coaxed laser light from the proteins.

The researchers filled optical microcavities with this protein before subjecting them to “optical pumping,” where nanosecond flashes of light are used to bring the system up to the required energy to create laser light.

Gather and colleagues from the University of Wurzburg and Dresden University of Technology in Germany, genetically engineered E coli bacteria to produce enhanced green fluorescent protein (eGFP).

To make the new laser

The researchers grew enhanced green fluorescent protein from jellyfish in E. coli cells because prior research suggested they were capable of producing polaritons (quasi particles that are able to carry excitations with them).

The protein was fashioned into a very thin (500 nanometer) film that was set between two mirrors. To create a laser beam, all the researchers had to do was shine a blue light into the device, which excited the proteins to the point of producing polaritons – soon thereafter, they spontaneously synchronized, producing a laser beam that was emitted out of the device. Fluorescent proteins can already be embedded inside living tissue for this reason, but they emit such a broad range of wavelengths that they can differentiate fewer than 10 cell types.

Because a laser emits such a narrow spectrum of light, fluorescent protein lasers could be used to mark thousands of different cells and a fluorescent protein laser would be safer than embedding lasers with conventional semiconductors, which can be poisonous.

It is noted that there are a few more challenges to overcome before the jellyfish-based laser is ready for everyday use, says Stéphane Kéna-Cohenat École Polytechnique de Montréal in Canada and still, the idea that a polariton laser made out of material derived from nature can work just as well as one with a traditional, highly engineered semiconductor crystal is interesting and surprising phenomenon.

The researchers filled optical micro cavities with this protein before subjecting them to “optical pumping,” where nanosecond flashes of light are used to bring the system up to the required energy to create laser light.

Natures lessons are in so much that we build, aircraft come to mind as one example, we have come so far and still have so much further to go, I hope to see a lot in my time alive here.

In the future there will be very little that man can't do, matter and energy will be converted back and forth to suit our needs, man wouldn't it be awesome to be able to peek a few thousand years ahead.

WARNING, out loud thought ahead.

Humanity rebuilds from the ashes of war, and we remember learned lessons about how things work, such as how to forge alloys, but the lessons regarding how our minds work and how to teach our young to reward innovation and co exist while encouraging productiveness are the most difficult challenges, if we could learn to be far sighted in our thinking and learn to maintain a balance between our individuality and our unity then we could apply the logical evolution of our scientific advances based on what works to our human evolvement.

Sadly even now our leaders fall way short giving in to greed and we allow it to continue, but the problem starts with how and what our children are taught, in order to evolve we must start at the beginning and empower better people with common values that we can all agree upon, yet we must have the fortitude to eradicate the snakes who can't be taught the basics and don't have the ability to learn empathy, and it's not even the misshapen lumps of clay who were taught murder and intolerance, it's their teachers and those who control them who are to blame, and ultimately us for allowing it as it is not something that we can just ignore.
Because often those leaders do know how our minds work and they use that knowledge to gain control/power/greed.

It's not a simple thing, but the more knowledge possessed by the more people the better off we all will be, but the trick is in sharing the truth and weeding out the misinformation, because those in control don't always want the masses to understand any more than is needed.

Apathy is Greeds seemingly softer sister, but she is just as destructive as apathy empowers greed to succeed, and a small amount of greed we all feel we need, it's not a simple thing and there is not a simple single answer, I suppose a constantly adjusting balance prevails, but the more people who know more, the less distance the pendulum will swing before correction of direction, the tricky part is both ways seem right from either extreme.

Technical/mechanical things are more of a balance between quality and economy, and less of a question of what works, science advances based on what works quickly while humanity has to slowly ratchet ahead with lessons relearned again and again, because knowledge is power and greed means some things we have to learn for ourselves over time, and as we have seen it can be worse when teachers teach their opinion rather than the facts and the history.....funny I never enjoyed history in school or even thought it to be useful, but now I want to learn as much as I can and what has been re-written.

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Useless troll fighting.
