Why Is (Almost) All Bioluminescence in the Ocean?

newtboy says...

My guess is terrestrial animals use fluorescence more often than bioluminescence as a simpler, less energy intensive, easier to evolve way to glow. Deep sea animals aren’t exposed to very much uv light to make them fluoresce (many shallow water sea creatures do fluoresce, like most coral) so need to produce their own light. Not so with most terrestrial animals.
That could partially explain the difference in frequency.

Murdering Cops Murder Cyclist For Crossing The Street

newtboy jokingly says...

Trump said on live tv that we should inject bleach and UV light into our bodies to fight covid.

Trump stared directly into the sun and fried his brain just like Jimmy Wichard on live tv. (Although if you’re dumb enough to stare into the sun, your brain is probably already fried….kind of a chicken or the egg thing).

A look back: Donny D.A., COVID & the crab of reason

newtboy says...

Absolutely…the little word flubs are funny, especially seeing how much the right makes of Biden’s diagnosed stutter that he’s all but overcome, but it’s the batshit crazy ideas that are the problem and clearly indicate breaks with reality severe enough for involuntary commitment.

Airplanes/airports….that’s semantics. A game I love, but inconsequential.

Thinking Washington fought with a modern mechanized army…seriously suggesting people should inject disinfectant and swallow uv lights, that’s a dangerous level of insanity or unbelievable stupidity and ignorance, as is ignoring such signs from leaders.

Stuck repeating “oranges”…that needs diagnosis…maybe sundowning? (I don’t know if that’s a medical term, but I mean when early onset dementia patients are almost normal until evening when they break down into full dementia.)


I think I’m going to need to watch that movie again, it’s been decades.

luxintenebris said:

yup. also never said to drink bleach - believe it was something about ingesting disinfectant and exposing internal body surfaces to UV - but the idea was almost the same. (Vader never said "Luke I am your father"; Bogart "Play it again"...)

he did talk about oranges.

odd as he is/was there were six separate occasions where i had to check various sources to conceive myself that the reports were genuine.

the one about the oranges...the cabinet meeting where they took turns praising him...sharpie-gate...NRA/gun nuts assassinating Hillary...drinking bleach...and not knowing Pearl Habor's history.

couldn't be.

'tho the orange thing is just too odd. kept thinking about the strawberries...

Midterm uphill battle for Democcrats

newtboy says...

Lol, and he said we should try injecting disinfectants or internal uv light against covid not vaccinating, he stared directly into the sun on live tv, and said the favorite thing he has in common with Ivanka is sex.

New York Nuclear PSA what to do in case of an attack

StukaFox says...

A car would be a perfect place to shelter:

1. The windscreen blocks UV light.
2. A car isn't going to collapse on you.
3. The car has actual shock absorbers to absorb the ground shock.
4. The car isn't innately flammable and even has a thermal barrier in the paint, metal and insulation.
5. The car has a radio.
6. The car is mobile and can (to whatever degree roads are passable) get you out of danger.
7. The car has a trunk to hold containers of water safely (double-safely if they're inside an ice chest inside the trunk)
8. You can sleep in a car.
9. In any circumstance in which a car was destroyed by the blast/heat, you were fucked anyway.

Monsanto, America's Monster

newtboy says...

In first world countries....yes, or close to that much. Agreed. Not world wide.

Mechanized harvest is accepted in "natural" old school farming. Agreed, it would fall under the "industrial farming" methods, but is one of the least damaging.
>1000 acre farms do not count as "family farms" in my eyes, even if they are owned by a single family. So is Walmart, but it's not a mom and pop or family store.

Again, mechanization is not the same as industrialization, but does still do damage by over plowing, etc. I'm talking about monoculture crops, over application of man made fertilizers, herbicides, and pesticides. Grain was farmed "by hand" since farming existed with few problems, but more work involved. The work it takes to rehab a river system because industrial farming runoff contaminated and killed it is FAR more work than the extra work involved in farming using old school methods (which does not mean everything is done with hands, tools and machines have been in use for eons).

Roundup doesn't "break down" completely, and doesn't break down at all if it's washed into river systems and out of the UV light.

Once again, machines aren't all of "industrial farming", they are one of the least damaging facets, and they are not unknown in old school, smaller farming techniques. BUT....overuse of heavy equipment either over packs the soil, making it produce far less, or over plows the soil, making it run off and blow away (see the dust bowl). If it was ONLY about machinery, and ONLY industrial farming used machines, you would have a point, but neither is true.

No, actually overproducing on a piece of land like that makes it unusable quickly and new farm land is needed to replace it while it recuperates (if it ever can). Chemical fertilizers add salts that kill beneficial bacteria, "killing" the soil, sometimes permanently. producing double or triple the amount of food on the same land is beneficial in the extreme short term, and disastrous in the barely long term. (See 'dust bowl')

Man power is far less damaging to the environment than fossil fuels for the same amount of energy. Also, the people would use no more resources because they're in the field than they would anywhere else, so there's NO net gain to the energy used or demand on the environment if they farm instead of sit at a desk, but machines don't use energy when idle, so there is a net loss to the energy required if you replace them with pre-existing people.

Yes, you quoted it directly, buy your characterization of what that meant was insane. You claim they said Monsanto worked on the project (and other things) because they're evil and want to do evil and harm. The video actually said they do these things without much care for the negative consequences to others, and that makes them evil. I hope you can comprehend the distinct difference in those statements, and that your portrayal of what they said is not honest.

I really want to do some UV night diving. It looks amazingly like Avatar to me.

Why are blueprints blue? - Big Questions - (Ep. 206)

oritteropo says...

I actually made a cyanotype print in high school chem class (a long time ago!). The process is that you make the solution, paint it on the paper, let it dry in the dark, put the object or negative on top, expose to sunlight (or UV light), and then rinse it in water to fix the print.

I also found this set of instructions which confirmed what I remembered

3D printing 100X faster and inspired by the Terminator movie

HugeJerk says...

The filament style of 3d Printers are cheap to operate and can be made to nearly any size.

A resin printer needs a photopolymer, something that solidifies when exposed to UV light. They also need a fairly strong projector and lens, which limits their build area.

A filament printer can use a lot of various materials, the most common being PLA (a bioplastic made from renewable plant materials) and ABS. There are many other materials, some are specialty that have an almost rubber like flexibility to them, to a filament that is made from wood and a binder, which results in an printed object that can be sanded and stained. And, since you are moving a print head, the only limitation to the build size is how big you have made your printer.

SFOGuy said:

I did not know that; so---why did the deposition 3Ds come into being? Was that about cost of materials, even though they are apparently 100X slower?
This is quite educational for me.

Real-Time Face Tracking & Projection Mapping

newtboy says...

Pretty neat, but can they do it without the white dots all over the face? Couldn't they make the tracking dots only visible in UV light, so the camera can track them but they don't interfere with the projected image? That would look so much better.

This Is What You Look Like In Ultraviolet

jimnms says...

@moonsammy At 1:52 and 2:42 you can see it's just an off the shelf Canon DSLR. I'm assuming it has some sort of filter that only allows UV light through.

@jmd I don't think those are hot pixels. Notice the spots aren't always in the same place, and in some scenes aren't there at all. In the last scene the spot only shows up as the UV filter slides over, so it's possibly dust on the lens, filter or sensor.
