Springtime in Oregon

People are roasting this person for asking a dumb question. But I think this is a valid query and the answer is actually pretty cool.

Unfortunately, you usually get a response like this.

This is accurate. But not very explanatory. "It's how light works" just feels a bit condescending.

We need to Bill Nye this shit.

The first thing you need to know is that light competes with light. And the brightest light is always the victor.

And this phenomenon is not specific to cameras. Our eyeballs also play in the light vs light competition.

Every person with a mobile phone has already seen this effect. What happens when you look at your phone on a really sunny day?

You can't see shit.

The sun is so overwhelmingly bright that it is reflecting light off the screen that is much brighter than the light being emitted from the phone.

However, newer phones are starting to have screens that are extremely bright. Up to 3000 nits in some cases. They are able to emit light brighter than the sun's reflection.

What happens to our eyes when we go outside on a sunny day?

Our pupils get as small as they possibly can. Smaller pupils let in a lot less light. And when they are that contracted, we can only register really really bright things.

But if we are in the dark, our pupils get super big. They allow in a bunch more light. And after we adjust to the dark, we can see really really dim things.

If our pupils stayed contracted and we looked at a starry sky, it would be as blank as the phone screen on a sunny day. You can even test this with an eye patch. Go into a very bright room and keep one eye covered for about 20 minutes. Then go outside and look at the sky with each eye. One eye will see stars and the other will not.

And this should give you a clue as to how light pollution works. Light bounces off stuff in the atmosphere. And when a city shoots a bunch of light upward, that light reflects back down and is much brighter than the stars.

The brightest light always wins.

Most stars are just incredibly dim. You need to be in a very dark environment in order to see them shine. You need them bigass pupils fully activated. And cameras need either a very large aperture (lens pupils), or a very long time interval to see them.

The sun is so so soooo bright. Many thousands of times brighter than distant stars. And the moon is also very bright. Especially if you are on or near the surface. The properties of moon dust, the regolith, are a near perfect diffuse reflector. Which is why astronauts struggled to see and photograph stars during their moon excursions.

If they opened up their camera apertures and did a long exposure, they'd just get a blank white frame.

There are dozens of photos in which that exact thing happened.

This is exactly what happens if you accidentally shine a flashlight directly into your eyes.

But it is a really cool ancient myth from one of Aristotle's essays written 2400 years ago.

And I think it is kind of neat that intellectuals from back then were trying to understand and figure out how light works. And it is impressive that a myth has lasted this long.

The problem is that the sky is a giant light source. A pretty bright one, in fact. People often forget that the sky is a giant hemisphere of scattered light because the sun is so overwhelming in comparison. It's just so much dimmer than the sun, it gets outshone on sunny days.

But you can see the sky being a light source on snowy days. If you look at photos of snow, you'll notice all the shadows are tinted blue.

That's the sky getting into the nooks and crannies where the sun don't shine.

So if you were deep in a well, you'd just see the blue sky.

HOWEVER, if you were to create a deep hole on the moon during lunar daytime, you could totally see stars. You'd be in a dark environment, your pupils would open up, there is no atmosphere to scatter light from the sun, and the glare of the surface wouldn't compete with the starlight.

Naomi is an anti-vaxx dipshit and not a great person.

But I think this question was asked in good faith and is also a perfectly valid query.

Moon nomenclature can be a bit confusing. People will reference the far side of the Moon and the dark side of the Moon and conflate the two.

From our perspective, there is a near side and a far side. The "near side" is always facing Earth. And people sometimes think the side facing away from us is also the "dark" side of the Moon.

But the far side is not always in darkness. Only when we see a full moon is it dark.

Astronomers have tried to update the terminology to lunar day and lunar night, but that hasn't really caught on as popular vernacular. It's hard to undo Pink Floyd's influence.

All of this is to say, it is easy for people to get confused about the far side of the Moon being illuminated by the Sun. It's quite common to imagine it as in perpetual darkness.

But lunar night is not completely in a void of darkness. The light from the universe does very dimly illuminate the lunar backside. And while traditional optics aren't easily able to see the Moon's butt, NASA does have a special UV camera that surveys the lunar night.

It's called the "Lyman-Alpha Mapping Project."

They love their clever acronyms.

I've seen people also confused about the lighting in this photo.

The Sun is directly behind the Moon, yet the left side seems to have light wrapping around to the lunar night side.

And the reason for this makes my light-loving heart full. Because light is light and it works the same way in space as it does in my studio.

This phenomenon is called "Da Vinci glow" or earthshine. The Sun is bouncing light off the Earth, and it is reflecting onto the side of the Moon. And even though it is usually too dim to see without a very long exposure, this eclipse was able to reveal it.

Here is what earthshine looks like to human eyes adjusted for darkness.

And here is a brightened, long exposure example.

It's literally just this on a cosmic scale...

There is also moonshine, which is more than just a legally dubious beverage.

You may have already seen an example.

The left is exposed as our eyeballs would see it. And the right is brightened with long exposure and a high gain setting.

The Sun is behind the Earth, but it is shining light off the Moon and giving very dim illumination to the night side.

The Moon is a big retroreflector. You have seen a different form of retroreflection when you are driving at night and the highway signs light up as you pass. Your headlights are shining directly back at you.

The special properties of Moon dust give it a near-perfect diffuse matte reflection. And when the Sun is in the right position, it acts similarly to our car headlights and the light shines back in our direction.

A studio reflector needs to be angled just right to shine the light exactly where you want it. The angle of the light is like a bumper shot in billiards.

The Moon scatters light in all directions like a typical matte surface.

However, a non-retroreflective matte reflection on a sphere typically has a bright center and then graduates into darkness around the edges. But the Moon's super matte retroreflection maintains brightness across almost the entire surface area.

So even though the Moon is quite small compared to the Earth, its regolith creates a powerful reflection of the Sun's light. You'd think a full moon would be twice as bright as a half moon, but this retroreflective surge makes the Moon roughly 10 times brighter.

They're not only beautiful green spaces but excellent public displays of history and art history, and if you care to look closely you can find out a lot just by studying stones.

For example- notice how few modern headstones are dedicated to young children versus the ones erected before vaccines were widespread.

The cemetery near here has the state's largest silver maple crowning its grounds. Many of the trees in older cemeteries are some of the largest and oldest trees in an area.

Cemeteries are for the living, not the dead. Enjoy them. Go birdwatching in them. Don't be stupid in them sure but don't be too afraid to touch them either.

Hans Christian Andersen's the Little Mermaid: Part II.

For Mermay this year, I picked up where I left off adapting the original Little Mermaid fairytale last year. The world below the water is painted like black & white shadow puppets, while the world above the water is painted like stained glass. The shadow puppets call back to old fairytale storytelling traditions and the work of Lotte Reiniger, while the stained glass imagery reflects how the original story associates the world on land with churches and holiness and the question of who gets to have a "human soul."

Typing this from Graphene now, in fact. But, both of those take the Android Open Source Project, without all the bloatware--and largely de-Google the whole thing. They give you much more control over privacy and what the apps you choose to install can do and access on your phone.

I know Graphene sandboxes everything, including the optionally installed Google Play Services which a lot of apps unfortunately require to run. (Lineage uses an alternative to Play Services instead.) So, you can install what would normally be unacceptably intrusive apps and just lock them away from pulling any funny shit with your data, or phoning home. Including the couple of Google things I do still keep around.

I also prefer running much more transparent, privacy-respecting open source apps where possible. Besides the transparency, I'd rather avoid the shitty tech corps entirely where I can. There are pretty good alternatives available for a lot of the usual suspects.

Needed a clean graphic for a project, and figured while I was vectoring I would put sex and magic back in.

The above is a video shared by smrchildsadness on Twitter, showing a person participating in a pride parade exchanging a pride flag with a person standing on his (am using his pronoun based on the TikToks/Tweets of what happened) doorway who had a Portuguese flag. There are sounds of cheers and crying and the two people hug each other as they exchange the flags. The man at the doorway then waved kisses to the crowd within the pride parade.

The Tweet says: "NO YOU DONT UNDERSTAND HE WAS WAVING THE PORTUGUESE FLAG BECAUSE HE DIDN'T HAVE A PRIDE FLAG AND THEY TRADED FLAGS AND HE'S SO EMOTIONAL TO GET HIS OWN PRIDE FLAG I'M EMOTIONALLY RUINED"

For context, apparently they were worried that maybe he's a nationalist because he was waving the Portuguese flag and some nationalists opposing the pride march were waving that flag. But upon interacting with him, it turns out he didn't have have a pride flag and he wanted to wave *a* flag in support of the pride march. So they had an exchange and now he has his own pride flag 😭🥹.

The image above is a Tweet by kunwara_ladkaa that says "I'm crying so much right now (Image taken by Manuel Fernando Araújo/Lusa)". The image shows the same man from the pride parade crying as he hugs his new pride flag.

The above image is a Tweet by dudz_zZzz that says "ainda não parei de pensar nele," which according to Google translate from Portuguese to English is "I still haven't stopped thinking about him." The image is a drawing of the person from the pride parade, crying as he hugs his new pride flag.

The largest and deepest sinkhole in the world is Xiaozhai Tiankeng, in Fengjie, China. Its name means something like "well of heaven" or "heavenly."

With its 662 meters deep, 626 meters long and 537 meters wide, it is one of the most impressive natural attractions on Earth.

it's just a phase

Hello everyone!

Last year I started designing a series of Coat of Arms, themed in the spirit of Pride Month and using different mythological creatures as heraldic animals. I now aim to turn these designs into wearable pins and will be running a Kickstarter in July to fund this endeavor! I have found a very trustworthy local manufacturer, who has already shown the quality of their craftsmanship with the first batch of test pins I received, just look at the detail they were able to produce!

Since I try to support local manufacturers, which produce pins with fair wages and are more ethical than outside of Europe, the pins are more expensive to create than through the usual pipeline via Asia.

I therefore seek to crowdfund the expenses since they would be more than I can afford. If you are interested and look forward to support this little endeavor, please follow the link below to sign up for a mailing list. People who signed up on the email list and pledged during the campaign will receive an exclusive sticker set by the end of a successful launch consisting of the following designs:
