05/16 International Day of Light

May 19, 2018 sunrise 6:25AM

~~~       sunrise_051918

The word light is probably most often used in the sense of visible light, or illumination, or concepts of that ilk where it is not meant to be the opposite of "heavy".  "Light", whatever it may be, is a chunk of the electromagnetic spectrum, which includes radio, TV, radar, microwaves, and hard radiation.  Beyond that, Schrödinger's wave equation extends it to particles, so it is somewhat universal and foundational.  Where light or other emf falls on the spectrum is determined by its frequency (f) or wavelength (λ), which are related by the formula λ = c/f where c is the "speed of light".  The visible spectrum typically runs from about 700 nanometers (RED) to around 380 nanometers (VIOLET).

So, why do we have an International Day of Light?  Damnfino.  Perhaps because the future appears so dark and bleak as to ecology, climate, poverty and all things socio-political?  Perhaps on the theory that shining a light into the dark corners will expose corruption and deceit, something unlikely in these times of unbridled censorship, even before the creation of MiniTruth, brought to us by those who gave us babies being tossed out of incubators, the Tonkin Gulf Incident, Weapons of Mass Destruction, and untold numbers of other fabulous tales and fictions.  Perhaps it is supposed to remind us of the light at the end of the tunnel, always there and ever receding, like Ahab, beckoning us to follow it?
 

On this day in 1918 1918 – The Sedition Act of 1918 was passed by the U.S. Congress, making criticism of the government during wartime an imprisonable offense. It was repealed less than two years later and then more recently gradually reinstated through various laws and edicts like the "Patriot Act" and section 1021 of the 2012 NDAA and the like and then even extended to include assassination of those living abroad.  Of course, probably the biggest change is that we somewhere along the way transitioned to an evidence free reality, where accusations and assertions, sometimes called "assessments" are deemed to be an adequate substitute for actual facts supported by actual evidence.

I like Newton's colorful prism experiment with light.

I mean there's light and then there's light. Plants are picky about it...

Me, I use LED's primarily when inside.

Thanks for the OT and light conversation!

great photosynthesis graphic. We mostly use LED's indoors though a few fixtures are still running CFLs which have refused to burn out.

I have several WYZE color bulbs which are internally programmable to have routines, turning themselves on and off according to programmed schedules and tunable as to frequency. I have some in the garage which illuminate a large tray of pea-sprouts one tuned to my best approximation of that blue/purple peak in the photosynthesis chart and one tuned to the red peak. (No sense wasting wattage on green(ish) hues, which will simply be reflected.) This was an experimental set up from which I have harvested 3 cuttings of shoots and the survivors are destined to be transplanted in the hopes of growing pea plants. I put 5 in one of my hanging planters yesterday and intend to do more over the next couple of days so that I can plant more seeds for shoots.

be well and have a good one

"shoots" - anywhere from 3 to 6 inches tall, then harvest. I [ut them in a variety of dishes, as does my wife; soups, stews, sandwiches, salads, omelettes, etc. I also yoss them with pasta. After about three cuttings they start to get woody and then my current plan is to transplant them outside in the hopes of getting a pea crop either to eat or to use as seeds. There are videos and other instructions on the whole process - look for "pea shoots".

be well and have a good one.

After all, it’s the light they don’t use — “waste light,” like the waste substances that animals excrete because they have no use for them?

On the other hand, green plants like actual animal waste because it makes good fertilizer. So a plant calling something “shit” might be a compliment?

Hi EL, Hope it's all good, for all!

Django, Liberace, and Fripp!?! Big day for heavies. Love 'em all. Masters amongst the masters.

In coral world 440 is where its at man. If you keep corals you will first have to fall in love with 440 brother. Actinic (ak-tin-ik) blue. Das is de majik holy wavelength. I was already into a 4x0 thing (before it was called that of course), so 440 came easy for me.

When the sun is not high in the sky, as in the first and last two hours or so of the day, most of the light getting any distance below the surface, such as down to corals is actinic blue, about 440nm. Proper reef tanks have (now LED and programmed) a couple hours of blue light (actinic) to start and end the bright photoperiod. I still have a half-dozen 4' actinic fluor. tubes. Now it is all LED.

The other majik coral number was 6500. This the kelvin of the sun at the equator at high noon. These two numbers were the silver bullet breakthrough in the 1980's that allowed coral keeping, and even indoor aquaculture of them. Learning about the 6500 kelvin and 440 nanometer actinic blue. In order to keep the photosynthetic alga that lives in and feeds the coral, alive. 440 man. If you fall a little short and just make it to 420, that will work too. Wink

Mrs. dysto just spotted a male Mourning Warbler at the birdbath which took a full monty spa treatment.

be well all!

@dystopian

Thanks also for all the info on coral world and 440. 440 is indeed the magic frequency, it is the "A" that everybody tunes to, 440 hz audio. More coincidental majik is that the 440 was my favorite distance in high school, a quarter mile and pretty much a straight sprint for the kid I was then.

today after the Buffalo mass shooting, apparently carried out by a teen with racist views using an assault rifle which was legal but was later illegally modified.

A major Supreme Court ruling is due soon which could further make things unsafe for the public, or depending on your pov give expanded muscle to alleged individual 2A rights. Regards a NY state law limiting conceal and carry permits. Court could rule that such "show justification" statutes are unconstitutional as they infringe on a person's right to carry concealed for the purpose of self-defense which purpose could reasonably be in most situations outside the home.

The Court in Heller (2013) improperly interpreted the 2A, imo, in seeing it as being about individual rights. The first part of the second amendment clearly states it is about guns in the context of a well-regulated militia.

But it's one of those poorly-worded amendments that in a better country would have been repealed long ago. It's just crazy that in most states, it's not illegal to purchase an assault rifle.

@wokkamile The shooter wore a black sun NAZI symbol that has become common among white supremacists internationally. The insignia of the Azov Battalion (our heroic allies in Ukraine) is a wolfsangel over a black sun, combining two NAZI symbols in case one was not enough.

go into podiatry to take care of all those foot shooters we can expect. I don't know what to think or say. But, looks like nothing will change before people themselves do, and I don't have a ton of hope for that.
