This is a photo I took 13 years ago of Jupiter and 4 of its moons (top). As a reference the image below is the simulated position at that same time.

You ever wonder why the small band of spectrum we can see (called visible light) is special? I mean almost all animals see in light ranges are are somewhere around here. I mean sure some can see a little farther into IR or UV but in general all animals see roughly around this same narrow band of frequencies in an otherwise infinite spectrum... So what is so special?

Its actually a quantum thing. Everything roughly around visible light and higher interacts with material by electrons jumping energy levels. However IR energy is absorbed by the bonds between molecules instead, which is why IR represents heat.

Basically visible light is right where these two modes intersect. Essentially they are the lowest energy part of the spectrum that is still high enough energy to interact primarily through changing energy levels of electrons. Essentially any more energy and it wont really get through the atmosphere as extreme UV is cut off.. any lower and it wouldnt be very effecieient cause most of the energy goes to heating the eye rather than seeing... So its right in that sweet spot.

LOL another bhlock due to an opinion expressed respectfully... man people have some issues if they cant even hold a conversation...

But yea apparently pointing out the terrorism of Israel is appalling **in addition** to the terrorism of the hamas is being a terrorist sympathizer now...

People just make up hyperbolic shit like it doesnt make them look like a fool... sorry it does.

Darnell Clayton :verified:  
@freemo Again with the false equivalence. I suggest we part ways, as I am not a fan of people who sympathize with terrorist groups, especially usin...

I just released a new version of Fedipage (a static site generator with full ActivityPub support).

Excited, the new version fixes a major bug and adds a few nice new features!

UPDATE: We tried something dead simple, and it worked.
1 golden potato
1 small onion
1 egg
1 tsp corn starch
a dash of kosher salt

Shredded the potato and the onion, then wrung the liquid out with a cheesecloth. Stirred in the other stuff, made flat patties, pan fried 'em.


No, seriously. The result was good enough that we might consider *tweaking* the recipe, but won't make big changes.

Sadly, all further refinements will have to wait until we have potatoes again. Whoops.

So apparently Musk is going to require **all** users pay to use twitter, no more free accounts of any kind.

Assuming this eliminates ads, might be the first move Elon made with Twitter that will make my personal experience better... not so sure about all the people who cant afford it though....

The MANDATORY FAILURE Kickstarter launched this morning, and funded in about four hours and twenty minutes.

I'm sorry I didn't post updates here, but I keep losing track of my various socials.

The printing is a teency bit off-square on some of the cards, but I'm not going to complain. Once the picture is in place nobody but me and maybe the hardcore #comics collectors will notice, and they often LIKE to see minor misprints. Also at 20 cents per card they're as cheap as free.

Fellow artists! I'm reporting in on the sketch card blanks I ordered (uprinting-dot-com):

1) Copic pigment liners are quickly colorfast (no smearing!)
2) Copic markers look good on them
3) the printing is is good.

$21 + nominal shipping charge, turned it around in about two weeks.

Almost a month ago, we asked our community for their opinions on moving the wiki away from Fandom.

Today we wanted to update you on what had happened since and what are our current plans. (1/4)

The most frequently asked question that I get about #JWST images is: "Why do the stars look like that?". In other words: why are the stars "spikey"?

The answer has to do with both the wave nature of light, the shape of the telescope's primary mirror, and the position of the struts that hold up the secondary mirror.

Attention! Today is World Pi Day, 22/7 or 3.14285, closer to the real value of Pi than American Pi (3.14). Please do not boost this as it confuses and annoys Americans.

I guess I should do a #introductorypost

I'm Ellie, a trans woman from the UK clinging onto the last few weeks of her 20s. My pronouns are she/her. I'm queer and autistic, so it's no surprise I'm always tired.

Outside of work, I spend most of my time playing, watching, talking or thinking about trading card games. Primarily
#yugioh and #pokemontcg, but I've been known to dabble in others.

I also:
* get very geeky about
* read a lot of
#fantasy (but never read as much as I wish I did)
* play a hell of a lot of modded

I don't really have any expectations for how I'll be using the fediverse; I'm usually more of a lurker than an active participant on social media. I can only wait and see!

The news isnโ€™t free.

And you get what you pay for: low quality opinion driven posts on social media for clout; or ad-driven commercial media in big organizations.

Or through the subscriber model, where Iโ€™m directly accountable to you.

We do posting on social media as a service to our followers!

But it ultimately will not be sustainable if we donโ€™t get subscribers who sign up to pay.

Does that a little more sense?

Have been blown away by the response here.

The advice: use apps to automate hashtags and posting; shorter threads longer individual posts; vary posting times. #Ukraine #counteroffensive

Also RTs are more important here because in an algorithm-less platform, no one will see us beyond our followers otherwise.

Any more advice?

Will you RT the first toot in this thread?

I used the phrase, "Social Consensus" to distinguish from "Workgroup Task Consensus." This is not a phrase you used.

By "small group of people" are you referring to an elite group, a "global cabal" directing the affairs of humanity? "Agency for people in general" to set policy? You mean voting and other civic involvement? If this is to what you refer, then you are in the realm of Chomsky's "Manufacturing Consent." If not, then I am unclear what you mean by "rational way to determine what society should look like" or what "utopic ideals" would have to do with wondering if this "needs to be in everything, no matter how small?"
