This set of panels has two of my favorite things:

Cyclops showing off his ability to navigate and maneuver without sight, even in the most dire circumstances.

Cyclops being able to find common ground and make an alliance with a former enemy for the greater good.

Possibly three 3. Having enough weird sexy mojo to get a lady who hates him entirely to save his life and follow him into a sewer.

I'm sobbing and screaming and throwing up. Where are you, Axiom's End/Noumena series by Lindsay Ellis fans...?? I NEED TO BE IN THE FANDOM BUT I CAN'T FIND IT!! Augh.

[dead-generations]

wow. I am regretting my focus on rocketry and not keeping up with payloadery. because everything going with Vast is amazing! Super exciting stuff, really really smart architecture and scope and planning. focusing on getting a simple single module station in orbit as fast and as cheaply as possible is brilliant and will put them ahead of everyone else, and they can leverage that into developing their real ambition for Haven-2.

Focusing on an externally identical modular scalable system is also so smart, as they can adjust or scale up or down (likely down) their ambitions based on market demand. and no one knows what market demand will be. the focus on minimal on orbit assembly is brilliant.

Very tight design, very realistic goals and read of the market, really intelligent design methodology, and just a brilliant idea to focus on getting something operating ASAP to learn by doing.

And they have done this all so rapidly, in next to no time. The big competitors in Skylab and Orbital Reef have had years more time, millions of NASAbux and direct oversight from NASA and Vast will have a commercial station in orbit and operational before any of them.

Definitely much more realistic and well planned than Orbital Reef - which is basically gaurenteed to both over promise and under deliver to NASA and still be too big for the market as it will exist. it's also moving faster and has a better operational timeline (planning for 3 years between Orbital Reefs launch and becoming operational is nuts. and they don't even have a crew vehicle to get to OR). I'm not sure Orbital Reef can win a contract realistically, it just costs too much and is too big and too ambitious and too slow, but Bezos is really good at winning contracts via lobbying and lawsuits

I still love skylabs 1 launch 1 station approach and I love that they're utilizing the era of big fairings we are in to maximise what you get from one launch. I can see ESA being keen on the design and if it is easy to manufacture they could provide bespoke stations just for ESA, JAXA or USSF. Haven-1 or 2 could also do this for cheaper but less space, which might suite JAXA and USSF quite well.

Axioms End Ampersand…. Save me Axioms end ampersand….. Save me!!!

[marigold-22]

I actually like this post in concept , I promise I’m not trying to be a hater but most of these proofs don’t work.

1.) does work and also shows the fact that 1+1=2 basically just by definition.

2.) doesn’t work because you defined addition wrong. I’ll give a similar albeit different way of proving 1+1=2 via set theory. First we define the natural numbers exactly as stated in your post, ie 0={} and S(n)=S(n-1) U {S(n-1)} then we say that a set X has cardinality(size) n if we have a bijection from X->S(n-1), a bijection is a mapping of elements from X to elements of S(n-1) such that no two elements of X are mapped to the same element of S(n-1) and every element of S(n-1) is mapped by some element of X. Then we may define addition of n,m by the cardinality of X U Y where X has cardinality n, Y has cardinality m and, this is important and what you missed, X and Y are disjoint meaning they have no elements in common. Then {🍎} has cardinality 1 via the bijection f(🍎)={} and so does {{}} via the identity map. Then since {🍎} doesn’t contain {} and {{}} doesn’t contain 🍎 we have {🍎} U {{}}={🍎,{}} has cardinality 1+1 then via the bijection g(🍎)={} and g({})={{}} we have {🍎,{}} has cardinality 2 thus 1+1=2.

3.) first off N has a monoid structure not a group structure and second off your proof isn’t really a proof, we can equip the set of natural numbers with many, many different monoidal structures in most of which 1+1 doesn’t equal 2, in order to equip the naturals with addition you have to define addition which means that you define 1+1 as 2 which makes the proof self referential. You can’t really give a proof that 1+1=2 via abstract algebra(although if someone can come up with one please tell me I would love to hear it)

4.) not a proof, intuition doesn’t constitute a proof

5.) in the base case of induction you assume 1+1=2 proofs can not be self referential.

TLDR: there are 2 maybe 3 proofs that 1+1=2(that are distinct enough to call different proofs) this post gives 1 of them and attempts 4 more all of which are incorrect.

PS: please keep making these sorts of posts, even if they are wrong sometimes, they’re fun to read

5 Ways to Prove that 1 + 1 = 2

1. The Peano Axioms (aka The Fancy Pants Proof)

According to this system, we start with 0 and define the successor function S(x), which means the "next" number after x. So:

0 is a number.

If x is a number, then S(x) is also a number.

Now, to prove 1 + 1 = 2, we define:

1 = S(0) (the successor of 0).

2 = S(S(0)) (the successor of the successor of 0).

Now, to compute 1 + 1, we use the addition operation defined as:

x + 0 = x

x + S(y) = S(x + y)

Thus:

1 + 1 = S(0) + S(0) = S(S(0)) = 2

So, we’ve just proven 1 + 1 = 2 using the Peano Axioms. 🧐

2. Set Theory (aka The “We’re Just Counting Stuff” Proof)

Let’s take a more "set-theoretic" approach. Set theory is the foundation of most modern mathematics, so here we go:

Consider the set {0}, which contains one element (zero). The successor of a set A is defined as S(A) = A ∪ {A}.

Let’s do it step by step:

0 = { } (the empty set).

1 = S(0) = { { } } (the set containing the empty set).

2 = S(1) = { { }, { { } } } (the set containing the empty set and the set containing the empty set).

Now, 1 + 1 is the union of two sets, so:

1 + 1 = S(0) ∪ S(0) = { { } } ∪ { { } } = { { }, { { } } } = 2

Look at that. Set theory is so neat, it just counts the things and boom, 1 + 1 = 2.

3. Abstract Algebra (aka The “We Can Make This Complicated” Proof)

Let’s prove it algebraically with some abstract structures! Consider the group Z2, the set of integers modulo 2. So, Z2 = {0, 1}, and addition in this group is:

1 + 1 = 0 (mod 2)

Wait, that’s not the right proof. Whoops.

Let’s try again with the addition of natural numbers. We know 1 and 2 exist in the set of natural numbers N. So by the basic group structure of natural numbers under addition, we literally just have:

1 + 1 = 2

In other words, we just used the closure property of N. Let’s move on, before we get lost in algebraic loopholes. 😂

4. Intuition (aka The “Common Sense” Proof)

You can also prove 1 + 1 = 2 the most intuitive way ever. Think about it like this:

If you have one apple 🍎 and you add one more apple 🍎, you’re just holding two apples 🍎🍎. How many apples? Oh, look at that—two. Simple as pie. 🍏

So, 1 apple + 1 apple = 2 apples. Seems legit, right? ✨

5. Proof by Induction (aka The “Math Loves Repetition” Proof)

Alright, get ready for a bit of mathematical recursion. Proof by induction is a powerful technique where we prove a statement is true by showing it works for the base case and then showing it holds for every subsequent case.

So let’s define 1 + 1 = 2 using induction:

Base Case: We know that 1 + 1 = 2 is true for n = 1 because, well... it’s true. 😅

Inductive Step: Now, assume that for some number n, we have n + 1 = n + 1 (this is the step where we take our assumption). We then prove that (n + 1) + 1 = n + 2, which holds by simple arithmetic.

Since both steps hold, by the principle of induction, 1 + 1 = 2 is true for all natural numbers!

So there you have it, folks: 5 ways to prove that 1 + 1 = 2. You’ve got your formal, set-theoretic, algebraic, intuitive, and recursive methods. Math can be rigorous, but it’s also pretty darn fun when you get creative.

Axiom 1: The world is a cosmic engine driven by suffering

Axiom 3: God allows suffering to drive us to worship.

Tomarrymort Starter Pack: 10 Recs for Getting Started in Tomarrymort

I've compiled a list of 10 medium to longfic recs that I think represent a great on-ramp to the Tomarrymort ship, as inspired by @sitp-recs’ Drarry for Beginners rec list. These are the fics that I would use to on-board people to the ship — gorgeous writing, superb characterization, and just as enjoyable on the first read as the 20th reread. 

As always, I am stunned by the talent in this ship! I tried to pick a good mix of different themes/tropes/settings, with a focus on elements that make for a good introductory work: the characters are recognizable; the setting skews more recognizable; both characters in the ship are a meaningful part of the story; the ship is central to the story; and the fics are for the most part complete (or updated within the last year). 

(Standard rec list disclaimers apply: please mind all tags and warnings on AO3 before reading; this blog abides by the age-old fandom axiom of don’t like; don’t read; recs are in alphabetical order by title.)

This is Part 1 of a 3-part series — I also have an Intermediate reading list and Advanced reading list coming up for readers who have been with the ship for a longer time.

For now, please enjoy these 1.3 million words of absolutely brilliant Tomarrymort reads that I hope will keep you hooked until the very last word:

Tomarrymort Starter Pack Recs

A Dangerous Game by @cybrid (E, 284k, WIP)

Setting: Canon Divergence – Book 5 Premise: If Tom’s diary horcrux gains a body at the end of Harry’s 5th year (instead of his 2nd), and then promptly kidnaps Harry and holds him captive over the summer. Lots of smut ensues. Why I rec it: The characterization is truly stunning — Tom Riddle is undoubtedly a psychopath — manipulative, thrill-seeking, kind of an irredeemable shithead — but he’s also dazzlingly charming when he chooses to be, someone whose presence Harry quickly grows addicted to. Their relationship can get incredibly toxic and fucked-up at times, but Harry has top-notch instincts and can hold his own against Tom. The plot is absolutely gripping, with the threat of (the main) Voldemort, who has set his sights on reclaiming his wayward horcrux, looming in the background. 

A Future Without a Face by @dividawrites (E, 115k, complete)

Setting: Time-Travel (1940s) Premise: If Harry travels back in time to Tom’s 5th year at Hogwarts, and Tom becomes obsessed with the new transfer student and wants nothing more than to possess him every way. Why I rec it: A 1940s time travel fic told entirely from Tom Riddle POV! Divida absolutely nails psychopath Tom — how he quickly gets singlemindedly focused on Harry, how the idea of possessing Harry consumes him, how he has no compunctions about doing completely fucked-up and destructive things to achieve his goals. There is so much tension between them from the start, so there’s not much of a wait to see some hot Harry & Tom action — and the conflict and tension only continues to build and build in dramatic fashion throughout the rest of the fic.

Either must die at the hand of the other by @metalomagnetic (E, 260k, complete)

Setting: Post-Canon Premise: If Voldemort survives the Battle of Hogwarts and is initially kept prisoner in Azkaban, until Harry takes him into Grimmauld Place under house arrest. Why I rec it: This fic is an incredible exploration of Voldemort at his most terrifying. Even if he starts off the fic with his magic temporarily blocked, he is no less powerful without his magic. The force of his personality is powerful enough for him to chip away at Harry’s initial resistance — @metalomagnetic manages to write one of the most charismatic, brilliantly manipulative, and psychologically devastating versions of Voldemort I’ve ever read. Harry ends up in a good place by the end of the fic, but the journey to get there is a roller-coaster of emotions that have permanently imprinted onto my soul.

In Somno Veritas by ladyoflilacs and @lordansketil (M, 158k, complete)

Setting: Canon Divergence – Book 6 Premise: If Harry starts appearing in Voldemort’s nightly dreams during Book 6, and Voldemort becomes obsessed with Harry after realizing he’s his horcrux. Why I rec it: This is one of the most unique fics I’ve ever read in this ship! Every scene is told in alternating POV between Harry’s POV and Voldemort’s POV, so you get to see how every scene unfolds from both of their perspectives. Voldemort is so intense and just as terrible as he is in canon, so his character is not at all sugarcoated, and Harry has so much compassion and heart and manages to fall in love with Voldemort anyway. The writing style is gorgeous, with richly detailed and emotionally-laden prose. Also, one thing that pleasantly surprised me is how funny their banter is! There were definitely a number of times where I laughed out loud in the middle of an otherwise really intense scene. Bonus content: also comes with a lovely sequel that made me melt.

Inevitabilities by @shadow-of-the-eclipse (T, 103k, complete)

Setting: Same-Age AU Premise: If Harry and Tom attend Hogwarts together and go traveling around the world after they graduate. A betrayal leads to their break-up, but after many years, Harry returns to find Tom in Britain, and the two of them are drawn back together again. Why I rec it: An excellent same-age AU with unhinged dark Harry and just-as-unhinged Tom. Their relationship starts out quite dark and twisted and unhealthy — and only devolves from there. The fic ends with the two of them as equals — utterly devoted to each other — but in an incredibly fucked-up way: “He loves Tom like a forest fire; wild and all-consuming, he wants to devour Tom, to claim him, to mark him, break him.” Isn’t that absolutely breathtaking?

love is touching souls (surely you touched mine) by @toast-ranger-to-a-stranger (M, 34k, complete)

Setting: Time-Travel (1940s) Premise: If Harry gets thrown back into the mid-1940s and meets Tom Riddle as a young man just graduated from Hogwarts working at Borgin and Burkes. Why I rec it: When Harry accidentally travels back in time and chances upon Tom Riddle as a fresh graduate, he realizes this is his chance to make a difference. While Harry is only in the past for a brief interlude, he leaves enough of an impression to change the trajectory of Tom’s life. The dynamic between Harry and Tom is rife with tension and witty dialogue, and the story is set during Christmastime, which lends a very festive and heartwarming atmosphere for falling in love with each other.

No Glory by @obsidianpen (E, 254k, WIP)

Setting: Voldemort Wins AU  Premise: If Voldemort figures out Harry is his horcrux when Harry surrenders in the Forbidden Forest, and decides to keep Harry instead of killing him.  Why I rec it: This fic showcases the absolute, terrifying genius side of Voldemort, in a universe where he wins the war and captures Harry at the end of book 7. I am stunned at how skillfully @obsidianpen portrays Voldemort as a brilliant political strategist — the courtroom scene where he manipulates the story and the audience so well stands out as a top 10 fanfic moment in my mind. Harry and Voldemort’s relationship is chilling from the very start, and grows even more unhealthy as Voldemort gets addicted to Harry’s touch due to the presence of the horcrux, but Harry later learns to turn that to his advantage.

The Fire, Burning by @parsimmony (E, 35k, complete)

Setting: Canon Divergence – Book 6 Premise: If Voldemort discovers Harry is his horcrux after Book 6, and kidnaps him to keep him captive by his side in his bed, inside of a lovely greenhouse setting full of friendly snakes on the grounds of Malfoy Manor. Why I rec it: The prose!! I am swooning over the prose! Harry is Voldemort’s captive in this fic, but he is so much more than that — and the emotions that gradually blossom between them have so much richness and depth and are utterly moving that I’m still drowning in the depths of intimacy that were portrayed. Their relationship unfolds in such a gorgeous and unrushed way, and the setting is so unique too — a lush and overgrown greenhouse that’s exploding with exotic plants and friendly snakes around every corner that imbues the fic with a very romantic, dreamy quality.

the pleasure, the privilege by @being-luminous (M, 20k, complete)

Setting: Canon Divergence – Book 6 Premise: If Voldemort is doused with Amortentia keyed to Harry, and starts sending Harry bizarre and gruesome courting gifts, like the bodies of the Dursleys.  Why I rec it: Breathtaking prose! Voldemort somehow ends up more terrifying when he’s trying to woo Harry than when he’s trying to kill him. Every single sentence had me on the edge of my seat, as Voldemort’s ‘gifts’ become more elaborate and devastatingly dramatic, until Harry basically has no choice but to respond to his overtures. The ending is incredibly clever in how it parallels certain plot elements of book 6, with an added Harrymort twist. 

The Untouchable by @treacleteacups (M, 75k, complete)

Setting: Canon Rewrite (Books 1-7) Premise: If Harry starts out his first year a little bit more suspicious and a little less wide-eyed and guileless, and subsequently gets sorted into Slytherin. He has many of the same encounters with Voldemort along the way as he does in canon, but his interactions with Voldemort will end up leading him down quite a different path. Why I rec it: A snappy, fast-paced full canon rewrite that still manages to fit in all the essential Tomarrymort plot points, between Horcruxes and Hallows and the major events of books 1-7, in a compact 75k words that doesn’t at all feel rushed. It’s a delightful journey following Harry’s character evolution from an overlooked, peculiar child who relies on wishy-washy wish magic to a confident (and still endearingly peculiar) young man who can challenge and hold his own against the great Lord Voldemort. Voldemort’s obsession with Harry deepens with every encounter that they have, as he finds ways to continually insinuate himself in Harry’s life and his mind and his dreams.

The Swastika Symbol 卍 The Buddhist swastika is called "manji" (卍) in Japanese, and it is known as "wan" (卍, 万)" in Chinese. In Sanskrit, it is referred to as "svastika" (स्वस्तिक), which means "conducive to well-being," derived from "su-" (good, auspicious) and "asti" (to be, to exist).

Meaning & Symbolism in Buddhism

In Buddhist tradition, the manji (swastika) is a sacred and auspicious symbol representing harmony, eternity, and the interconnectedness of all things. Its arms, usually turning to the left (counterclockwise, 卍) in East Asian Buddhism or to the right (clockwise, 卐) in Indian traditions, symbolize the revolving forces of Dharma and the eternal cycle of life, death, and rebirth (Samsara).

Deeper Symbolism

Cosmic Harmony – It represents the balance of opposites (like yin and yang in Taoism), reflecting the unity of all phenomena. Buddha’s Heart and Footprint – In many Buddhist iconographies, the swastika is found on the chest or palms of statues of the Buddha, signifying his infinite wisdom and compassion. The Wheel of Dharma (Dharmachakra) – The swastika is a geometric simplification of the eight-spoked Dharma Wheel, showing the ever-moving cosmic order of the universe. Four Cardinal Directions – It extends to the fourfold nature of existence (North, South, East, West), linking it to space and the infinite expanse of reality.

Esoteric Buddhist Perspectives

In Vajrayāna Buddhism, the swastika often appears in mandalas and yantras as a gateway to higher consciousness. It is also associated with certain Bodhisattvas, particularly Maitreya, the future Buddha.

In Japanese Esoteric Buddhism (Shingon), the manji is a symbol of the primordial truth and the cosmic reality of Mahāvairocana Buddha (Dainichi Nyorai)—the central deity in many tantric practices.

Connection to Other Traditions

In Jainism, it represents the four states of existence: gods, humans, animals, and hell-beings. In Hinduism, it is a solar symbol linked to Surya (the Sun), Vishnu, and Ganesha. In Western Esotericism, the swastika has been used as a solar, alchemical, and Hermetic emblem, predating its later misappropriations.

The Buddhist Swastika (Manji) in Western Hermeticism and Qabalah

The manji (卍 / 卐) in Buddhist symbolism aligns deeply with principles found in Western Hermetic Qabalah, Alchemy, and Tarot, especially when understood as a rotating force of cosmic balance, evolution, and divine will.

1. The Swastika as the Rotating Cross of the Elements (Tetragrammaton & Tiphareth)

In the Western Hermetic tradition, the cross (☩) is a foundational symbol, representing the four elements, the four directions, and the divine tetragrammaton (יהוה - Yod-Heh-Vav-Heh). The swastika, being a rotating cross, adds the idea of motion, transformation, and the eternal turning of the cosmos.

Tiphareth (תפארת), the Solar Sephirah in Qabalah, aligns perfectly with the swastika’s solar connotations, particularly in Hindu and Buddhist traditions. The Golden Dawn viewed the swastika as a rotating force that could symbolize either constructive (deasil, clockwise) or destructive (widdershins, counterclockwise) currents, akin to the alchemical cycles of dissolution and coagulation.

This movement mirrors the Hermetic axiom: "As above, so below"—the continual unfolding and refolding of divine patterns in the physical world.

2. Tarot and the Breath of the Swastika (Manji)

If we think of Tarot as a breath cycle, the swastika represents the continuous inhale and exhale of divine energy through the suits and elements.

The Four Arms of the Swastika = The Four Suits of the Minor Arcana Wands (Fire) – Creative motion, the Will in action Cups (Water) – Emotional currents, the inner spiral of the soul Swords (Air) – Thought’s dynamic process, movement in mind Disks (Earth) – The physical realization of spiritual laws

Thus, the swastika aligns with The Wheel of Fortune (X) in the Major Arcana, which reflects the perpetual turning of karma, dharma, and cosmic cycles.

3. The Swastika and the Qabalistic Lightning Flash

In Hermetic Qabalah, the Lightning Flash of Creation, which descends from Kether to Malkuth (forming the path of divine emanation), has a rotational counterpart: the return ascent of consciousness—aligning with the swastika’s cyclical motion.

The descent (clockwise, 卐) aligns with the involution of divine force into matter The ascent (counterclockwise, 卍) represents spiritual return, enlightenment, and Nirvana

This matches the Buddhist idea that the swastika embodies the eternal path of awakening—a journey from illusion (Malkuth) back to divine unity (Kether).

4. Esoteric Alchemy: The Swastika as the Prima Materia

In Alchemy, the swastika symbolizes the dynamic transformation of the Prima Materia (first matter) into the Philosopher’s Stone.

The turning arms represent the alchemical process: Calcination (Fire), Dissolution (Water), Separation (Air), and Conjunction (Earth). In this sense, the manji is a glyph of transmutation—the constant reworking of base consciousness into divine gold.

This echoes Vajrayāna Buddhist teachings, which treat the mundane world as raw material for enlightenment, just as an alchemist transmutes lead into gold.

5. The Swastika as the Key to Magickal Motion (Chokmah’s Whirlwind)

Chokmah (חכמה) in Qabalah is associated with the whirlwind of divine motion—it is not static wisdom but active, living force, the archetypal "Will to Evolve."

In this sense, the swastika is a glyph of Chokmah’s energy descending into creation (Yod, the first spark) The rotation signifies the primal whirlwind, the storm of existence, which eventually crystallizes into form (Binah, structure).

Thus, the manji is a cosmic yantra of divine will in perpetual movement—never fixed, always flowing. Final Synthesis: Manji as the Breath of the Divine

The Buddhist swastika is a universal expression of the Hermetic Great Work:

1.It shows the interplay of creation and dissolution, much like the Tree of Life and the Lightning Flash. 2.It is a breath—inhale (form), exhale (transformation)—mirroring the cycle of Tarot and Qabalah. 3.It represents the eternal journey of the soul, the Wheel of Fortune turning through Samsara toward ultimate enlightenment. -Tarot of Eli

[shinosarna]

The only distinction that would make sense is that Vania is for game with focus on RPG elements (i.e. numerical statistics that you increment by playing and not just by exploration) and Metroid is for gamnes that don't.

Because let's face it, "Metroidvania" is not actually named after Metroid and Castlevania - it's named specifically after Super Metroid and Castlevania: Symphony of the Night. And SotN being an action RPG is easily it's largest difference from SM.

do you prefer the metroid or vania side of metroidvania

I don't think it's useful to taxonomise them that way. I've never seen anyone produce a definition of what the distinction between "metroid" and "vania" is that didn't end up with at least one actual Metroid or Castlevania game on the "wrong" side of the dividing line, much less one that could fruitfully be applied to the genre as a whole.
