I'm pretty sure Tasker could handle it. You could probably also limit it to just playing notifications for a single app, or only when connected to one specific BT device, if that's what you're after.

My understanding is that "the speed of light in a vacuum" isn't really about light itself, but rather about the speed limit of cause and effect, or "information", in our universe. Light just happens to move at that maximum speed.

In quantum mechanics, even if you can have an entangled pair (separated by long distance) collapse instantaneously, that system still couldn't be used for instantaneous communication that exceeds the speed of light in a vacuum. (At least, that is what I have previously understood.)

I read all three articles, and didn't find an answer to this question:

When they say "quantum teleportation of information" - The speed of that teleportation itself is still limited to C, right?

I tried to post this video directly, but it got removed. So, here is how to make your own sound-dampening baffle box for a home server:

To be clear, it's not that they shoot laser beams from their feathers as some sort of mating ritual or defense mechanism (which, honestly, is probably how I would have used my own laser feathers, if I had them), but that there are strikingly identical nano structures that can reflect back a little bit of laser light, under laboratory conditions:

After staining the feathers with a common dye and pumping them with soft pulses of light, they used laboratory instruments to detect beams of yellow-green laser light that were too faint to see with the naked eye. They emerged from the feathers’ eyespots, at two distinct wavelengths.

From what I understood of the article, it's not just the size (which you can get from merging previous black holes), but the combination of size, speed, and angle that are raising eyebrows.

Smash two random black holes together, and the odds are, they're spinning at different random angles. Do that a bunch of times, and unless their angles all happened to be lined up just right, the the resulting spin will be a lot slower than the maximum speed a black hole of that size can spin. But these were spinning at 80% and 90% of their max speed.

Okay, so maybe they were both "normal sized" black holes that gobbled up a lot of matter around a galactic nucleus? That might work, except then you'd expect them to both be spinning in the same direction - but they weren't.

So, none of the scientists' predictions are really matching what they actually observed. Maybe it was one of those things, maybe those models are off a bit, or maybe there's another model to explain these kinds of black holes that we just haven't thought of yet.

TiddlyWiki might be a good option.

From the research paper:

(Glowing red spider silk strands

a) Comparison of wt and mRFP-modified major ampullate silk fibers rolled on a capillary glass (scale bars: 550 µm).

b) Strong red fluorescence can also be seen in the major ampullate gland (scale bar: 277 µm).

c i) The genomic implementation of mRFP into the major ampullate silk was confirmed by amplifying the mRFP DNA sequence extracted from the spider's leg. Only those spiders with red fluorescent silk (scale bar: 138 µm) showed the mRFP sequence-derived signal in the agarose gel.

C ii) Total-RNA was extracted from the glands, reverse-transcribed, and subjected to R-TqPCR and a melting curve analysis showing a peak at 83°C and 87°C based on a small and a large, amplified fragment.

I think it's 100% a didgeridoo, but one that has been molded into a shape superficially resembling a saxophone.

As a longtime didg player, I can tell you that the thing that makes this absolutely worth every penny is not how light it is, the paint job, etc, but the fact that it can hit so many "hoot" notes (what they call "trumpets"), and that each hoot note is tuned to be in the same scale as the main drone.

Most didgeridoos have only one, or maybe two hoot notes, but I watched some other videos of these things being played, and I'm seeing four or five hoot notes, in addition to the main drone.

At that point, it's starting to grow beyond the realm of wind percussion instrument, into something that can play melodies.

I think you actually nailed the point perfectly. Part of the social contract is that an employer will provide enough money to meet the basic needs of the employees. When the employer fails to do that, employees can feel like "wage slaves", or prisoners, who are being mistreated.

I recently produced a radio drama on what life was life before we had child labor laws, and how they came about. If you're interested, it's called "Florence Kelley, The Children's Champion."

I think it's more accurate to say that a brain refusing to bring up a certain memory, is what makes it a repressed memory. "Recovering" a repressed memory can happen as part of trauma therapy, or it might happen by itself years later.

Trauma itself causes incredible changes in the brain, in some very non-intuitive ways. The brain has a number of different strategies for protecting the person, the "self", from unnecessary suffering, and it doesn't let go of those defense mechanisms until "it" feels safe to do so.

Honestly, out of all of the ways that the brain can respond to trauma, repressed memories is one of the simplest and easiest things to understand.

The fact that false memories can also be demonstrably created... Well, that muddies the waters a bit, it makes things more complicated to sort through, but it's entirely reasonable to assume that there is a mechanism for memory repression, and there's also a mechanism for creating false memories.

Ooohhh! You know what, I learned something new today! Thank you so much for taking the time to explain it in a way that made sense to me.
