Catching prey using Vortices

I was reading about Vortices and after hours of research online, out of the blue I stumbled upon this amazing bird. This is the Red Necked Phalarope and from the looks of it seems to have put vortices to a really productive use - catching its prey.

By rotating around ~60-80 times a minute, it produces an upward vortex that sucks out insects/bugs/crustaceans from the water, which it swiftly picks up with its beak and eats. ( This one would have aced the Fluids class for sure :D)

This is analogous to tornadoes sweeping up cars and houses along its way in an upward swirl.

Mind Blown!

** The actual dynamics of vortices of course is waay more complicated. ;)

*** There are three species of phalarope (red-necked, red/grey, and Wilson’s), and they can all feed like that.            

7 Best Omegaverse Mangas

Abarenbo Honey ~  STATUS:ONGOING

Like many mangas this story has the main couple a side story couple. Personally, I like the main couple most (cause the main omega kills me❤️😂) Vol 1: Abarenbo Honey 1-4) Abarenbo Honey Takuma is a badass Omega delinquent more preoccupied with constant fights for his turf than with being cautious and taking his heat suppressing medicines. One day, when he challenges his archrival Hachi, something strange starts to happen with his body! 5-6) Kakurenbo Honey Stoic Yakuza Hanasaki Mitsuro was always able to suppress and hide his Omega side. But what will happen to him after ending up on secluded Island with a young Alpha master without the access to the medicines? 

(2) Jappa no Amane ~ STATUS:COMPLETED

I like this one because it’s so different. And it comes with a side of Mpreg(sorta) A college student named Mitsuko works at his uncle’s hostel. On his way from an errand, he finds an unconscious yokai, Tenshi. When Tenshi wakes up he acts ferocious and arrogant. To express his gratitude to Mitsuko for saving his life, he also becomes a guest at the hostel on his own accord until Mitsuko decides what he wants. After being acquainted with Tenshi, gradually he opens his heart to Mitsuko. Suddenly Tenshi’s body transforms into an adult-like appearance and harasses Mitsuko! 

(3) kashikomarimashita destiny ~ STATUS:COMPLETE 

The story tells of a stubborn young master and his loyal servant. Because of their statuses, their love story is at the mercy of fate. Aoi is the heir to his family, but due to some discord between him and his stepmother, he is forced to leave the house. And there to support him is his childhood butler, Miyauchi. After living his days being doted on and served, Aoi finds his position reversed, where he has to work all day. And what has supported him throughout this lifestyle is his unrequited love of 5 years for Jirou, the heir to the Saionji family, a leading automobile maker.

(5) Pendulum ( and Remnant): Kemonohito Omegaverse 

pendulum ~ STATUS:COMPLETE

This is an omegaverse where manbeasts and humans co-exist.

Manbeasts can only be born from an omega (Ω) human. Kai is a young Ω abandoned by his parents. He was picked up by Luard (α), the head of the Siegfried family, the most powerful manbeast clan in the country, to bear their children.

Up until then, he was treated as a nuisance by those around him, so he was drawn to Luard who treated him as a human being. Before he knew it, now he dreams of becoming a pair with Luard…

However, he learns that the Siegried family doesn’t form pairs and goes through multiple omegas to leave more descendants…And the destiny of an omega in heat is to go with multiple manbeast partners as well…

remnant ~ STATUS:ONGOING

There wasn’t a good description of found so here’s mine… 

Takes place after Pendulum, with the side couple as the main one. Fluff and smut ensue… 

(6) Totsugimasen Kara! ~ STATUS:COMPLETE

Itsuki a fresh high graduate was ordered by his mother to work as a servant under the Tenmei family.

Little does he know, that he was actually one of the candidates into becoming the bride of Tenmei’s young master named Jin.

But competition proves to be fierce as the contenders are all male Omega from well known families while he was only from an ordinary household. (basically the cutest short omegaverse story you’ll ever read.)

(7) unmei no kisu wa oazuke ~ STATUS:ONGOING

Nanao, an omega, is working the nightlife but he hates arrogant Alphas.


Arisaka is a serious Alpha that was brought by his co-worker into Nanao’s workplace.

The two had an argument but as soon as Nanao touch him, his heat suddenly came up.

When you are in the combat zone, agility of a fighter jet is of utmost importance. But as an engineer, if you have already fiddled around with the wing structure your next option would be to fiddle around with the direction of the thrust.

Thrust Vectoring

Thrust vectoring is primarily used for directional control in rockets and jets. And one achieves this by manipulating the direction of thrust .

This generates the necessary moments (and forces) that enable the directional control of the aircraft. 

An aircraft traditionally has three “degrees of freedom” in aerodynamic maneuverability; pitch, yaw and roll. **

The number of “dimensions” of thrust vectoring relates directly to how many degrees of freedom can be manipulated using only the vectored engine thrust.

Therefore, 2D vectoring allows control over two degrees of freedom (typically pitch plus either roll or yaw) while 3D controls all three.



Lockheed Martin F35B

The F-35B short takeoff/vertical landing (STOVL) variant is the world’s first supersonic STOVL stealth aircraft.

It achieves STOVL by swiveling its engine 90 degrees and directing its thrust downward during take off/lvertical landing mode.

In the following gif you can witness the transition from a 90 degree tilted engine towards a forward thrust engine during flying.

Unlike other variants of the Lockheed Martin F-35 the F-35B has no landing hook. And as a result, witnessing its landing is rather pretty special.

But nevertheless, this is one of those posts which addresses a topic that has been a gold mine for research. If this sort of thing fascinated you, there have been a lot of research conducted by NASA do check them out.

Have a great day!

The Revered Omega

I am a sucker for the headcanon / AU of a Revered Omega where the Omega is seen as some delgacy and should be treated like royalty.

  • These AU’s tend to have a low precentage of Omegas in their world.
  • Omegas would never be allowed to go anywehre without a Beta or Alpha accompanying them.
  • They tend to not be allowed jobs unless it’s family related.
  • Being mated to an Omega is an honor!
  • Suiters would shower them with gifts.
  • Parents tend to arrange their Omega child’s marriage.
  • These Omegas are usually not allowed to do any sports.
  • They probably tend private schools or are home schooled.
  • Their life is usually controlled by a parent figure.
  • These Omegas tend to be shy and soft spoken.
  • They can also be undeceive or uncaring of what to decide when given choices. Like, “Why should it matter? You’ll end up making the final decision anyways.”


But, I also like the idea of a Reverd Omega who is outspoken and a handful

  • They would always be running off to go see what is in a shop’s window.
  • Their Beta or Alpha care-taker is always sighing. Their job isn’t boring.
  • These Omega are always making new friends, no matter the dynamic.
  • They don’t like their dynamic stop them from wanting to work or doing activities that make them break a sweat.
  • Totally the type to sneak out of the house with their friends. Then they get grounded for two weeks.
  • They beg their parent’s to go to a public school.
  • They dress themselves, they start trends.
  • Some Alphas or Betas see this Omega as un-mate-able because this Omega is outspoken and not stereotypically submissive.
  • Arranged marriage? They think not!

A trick of tether dynamics: If you drop a metal ring down a straight chain loop, rather than falling straight off it’ll catch itself into a loop, because a travelling wave moves down the chain. The whiplash of the wave kicks the end of the chain upwards. The ring falls into the hole and gets stuck. Try it yourself!

my projectile/relative motion test was 2 days ago and we are moving on to dynamics. not particularly confident about the test though, because it had such a small denominator (not much room for little mistakes) and I’m not fully clear with relative motion so I only have my fingers to cross.

in other news, hurray that it’s officially fall season (even though it’s going to snow next week) I’m ready for the beanies, baggy sweaters, and black boots.

I hope you’ve all been feeling well, treating yo selves, and loving yo selves, and if you’re not then it’s okay because I think you’re pretty rad ♡

Omegaverse Headcanons!

This is my first time writing out headcanons so I’m sorry if they’re messy and hard to understand! I wanted to do omegas courting.

  • An omega staying up for half the night, googling ‘what to get the alpha you like’ and staying on sites like pinterest for hours until they give up or find what they wanted
  • Constantly hearing the omega curse or cry out when they prick their fingers with the needle while trying to make a gift for the one they like 
  • Messy scarves with bad sewn in happy faces but they still love it and wear it anyway
  • Gifting their favorite book along with a bookmark they used all the time
  • ignoring when their friends or family say that they should be the ones receiving gifts and being courted 
  • The alpha being surprised when the omega pops up out of nowhere with this bright smile along with a wrapped box
  • Initiating hand holding 10/10
  • Hitting up every single craft store they can find only to go back a few hours later since they messed up 
  • Taking the time to scent the small plush items they decided to buy for the other
  • The alphas friends snickering at how cute the omega was when handing over the gift and the alpha’s shy reaction
  • Giving them sweaters/hoodies that they know they can steal and wear later if the courting goes successfully

Feel free to send me in things you want headcanons written on! Thank you so much!!

Science Busts The Biggest Myth Ever About Why Bridges Collapse

“Just four months later, under the right wind conditions, the bridge was driven at its resonant frequency, causing it to oscillate and twist uncontrollably. After undulating for over an hour, the middle section collapsed, and the bridge was destroyed. It was a testimony to the power of resonance, and has been used as a classic example in physics and engineering classes across the country ever since. Unfortunately, the story is a complete myth.”

If you’ve only ever seen one bridge collapse ever, it was probably the Tacoma Narrows Bridge. On November 7th, 1940, high, sustained winds sent the bridge from an up-and-down undulation into a twisting, rocking pattern that led to the eventual collapse of the structure. It’s been used as a classic example of resonance at work, similar to how a wine glass will shatter when exposed to the right frequency pitch. While the shattering of glass is due to resonance, and it is a real phenomenon, the numbers just don’t add up for the bridge. Instead, it’s a much more intricate phenomenon that caused that infamous bridge collapse, known as flutter. If you’ve heard the resonance explanation, you’re not alone: it’s probably the most common misconception in all of physics and engineering!

Don’t be fooled any longer. Come get the full – and correct – story today!

Badass Omega Lance?

So I was thinking an AU with a/b/o dynamics

Lance is an omega but he hates society’s views on them so he says fuck alphas and most betas and he riots a lot and is hardcore asf and carry’s around this Beretta gun like its his baby and is VERY trigger happy and like Idk thats what I’m thinking for Lance.

Shiro however is Alpha prime but hates the role he’s designated in (he’s like some senate alpha or some shit that makes decisions), he doesn’t want to treat omegas bad and although he’s very dominate he’s like really kind and docile and he and Lance cross paths and he’s immediately smitten with Lance and chases him around trying to court him and Lance isn’t having any of that at first so he rejects Shiro a lot.

Basically like a revolutionary/crime au with a/b/o dynamics and its kickass with lots of knowledgeable things and smut.

Cause smut is great

*Bonus if it has like real world events
incorporated in it,👍

Alpha Headcanons

As promised, here are headcanons I keep for Alphas

~Alphas aren’t the most possessive (it’s Omegas) they just have the most physical and loud reaction
~ Alphas are very territorial though, so they don’t usually get defensive unless they feel someone is encroaching
~ Alphas loose their rational side when their omega is in heat. Though if they plug up their nose it helps if they need to get home
~ Alphas usually have more Beta friends than anything. Because they will subconsciously (or consciously) compete with Alphas. And an Omega mate doesn’t like their Alpha with Omegas friends
~ Alphas are normally less social than Omegas, nobody really knows why.
~ Female Alphas cannot have kids (like a male omega can’t get someone preggers)
~ Female Alphas are usually just as tall as males
~ Alphas (all mates) cannot abused or neglect a mate, because their mates scent requires them to protect and provide.
~ Alphas love ‘Take your kid to work day’ if you think new omega moms show off their kids, you ain’t ever seen a proud papa
~ Alphas naturally take on leadership rolls, like in a crisis they will be able to step up and get things done the most naturally. Not to say betas and omegas can’t, it just comes more naturally to an Alpha
~ Contrary to what Alphas in HS tell you they don’t sleep around, it’s considered a horrible offense and their destined mate could potentially reject them.

That’s all I got for rn, hope y'all enjoy 😊
