Why would a Southern European even consider a holiday in Briton? Do they really crave bad weather?

Sunny days are overrated.

Ever thought, oh wow, particle wave, wonder what that would look like?

They look like this! Here is an actual electron microscope photo...

There is a link that somewhat explains the methodology, more than I can follow, for sure. I get some of it. I'm totally lost as to why they are doping the silver wire?

As far as the picture (top part, 3D) it looks somewhat how I conceptualized in imaginanation. It is more or less constant in frequency. It cycles sine every 90 or 180 degrees, so this matches theory as it switches from magnetic to electric to magnetic etc. I can't tell which direction is phase and which is frequency, I wish I could puzzle that out. In a sense both are phase, both are frequency, depending on whether you are considering it as magnetic or electrical? lololol electromagnetics. I'm guessing that the purple, of larger amplitude, is closer to the source of emmission, i.e. more energetic, and diminishing by inverts with distance.

The bottom just looks like a 2D rendition of the top, sort of like a topographic map.

Fisher Price fridge magnets and their effect on synesthesia.

The standard theory is that synesthesia results from random over-wiring between brain areas—in this case, between regions that process letters and those that process color. This model of random connectivity predicts that each synesthete’s color associations will be different: Sue might have a yellow “B” while Tom’s “B” is red.

However, a suspicion about the standard model arose in 2006, when two Stanford scientists, Drs. Nathan Witthoft and Jonathan Winawer, found a synesthete whose colors had a distinctive pattern, cycling through red, orange, yellow, green and blue. When asked about the pattern, the synesthete pointed out that her colors matched those on the popular Fisher Price magnet set she had as a child—in which A is red, B is orange, C is yellow, D is green, and so on. By 2013, Winawer and Witthoft had found 10 more synesthetes whose colors echoed the Fisher Price magnet set.

First Warm-Blooded Fish Found

No matter how deep they dive, however, their body temperature stays about 9 degrees Fahrenheit (5 degrees Celsius) warmer than the surrounding water. Fat deposits around the gills and muscles help insulate the fish, the researchers found

I automatically thought it would maintain a temperature in a fairly narrow range the way we do, but it just maintains a bias above ambient condition. It's still pretty cool, as new discoveries go.

Looks like it would taste good.

That article's a bit misleading. We've known for decades that some large fishes (e.g. Great White Sharks) can heat their bodies to several degrees above the surrounding water.

Similarly, we've known for decades that many of the thunniform fishes (tunas and their relatives) have specialized adaptations to heat some of their body tissues to well above the temperature of the surrounding water -- thus improving their swimming speeds, vision, reaction times, and digestive efficiency.


So it's neither true nor useful to say that the opah is the first fish known to be "warm-blooded." What makes this species unique is that it uses a countercurrent heat-exchange mechanism in order to do so, and that it can heat its entire body, despite its relatively small size. (Some really big fishes are mass endotherms -- their very bulk means that they're sufficiently well-insulated that they can retain body heat even in cold water, and so maintain body temperatures well above that of the surrounding water.)




But then, as I've argued before, there's a reason that biologists tend to dislike the terms "warm-blooded" and "cold-blooded." They're so vague as to be all but useless.

Specifically, the vast majority of people, when they hear the term "warm-blooded," think that it's describing an animal that is an endothermic homeotherm -- that is, an animal that generates a significant amount of body heat and uses it to maintain a warm (roughly 37 - 40 degrees C) and near-constant body temperature. This is true of most [though not all] birds and mammals.

By contrast, the vast majority of people, when they hear the term "cold-blooded," think that it's describing an animal that is an ectothermic poikilotherm -- that is, an animal that doesn't generate a significant amount of body heat, and so whose temperature fluctuates according to the temperature of its surroundings. This is true of most reptiles, for example (and fishes, for that matter).


The opah is an endothermic poikilotherm. It can generate enough body heat to be significantly warmer than its surroundings, thus it's an endotherm -- but it cannot generate and retain enough body heat to get its temperature up to that of a bird or a mammal unless it's in water that's already quite warm. It's not a homeotherm, because it can't maintain a more or less constant body temperature the way that a typical bird or mammal can -- its body temperature still fluctuates according to the temperature of the surrounding water, just as is true of practically all fishes.

What is Dark Matter and Dark Energy? - YouTube

It's boggling to try and imagine how something crops up from nothing and still can't be observed or measured because it's nothing and when it's done spawning from nothing maybe goes back to being nothing. Dark Matter/Energy be trippin, y'all.

Maybe when space expands it creates new space to fill in the gaps.

HOW CAN THERE BE GAPS IN SPACE?
