flow dynamics

We’re used to radiation being invisible. With a Geiger counter, it gets turned into audible clicks. What you see above, though, is radiation’s effects made visible in a cloud chamber. In the center hangs a chunk of radioactive uranium, spitting out alpha and beta particles. The chamber also has a reservoir of alcohol and a floor cooled to -40 degrees Celsius. This generates a supersaturated cloud of alcohol vapor. When the uranium spits out a particle, it zips through the vapor, colliding with atoms and ionizing them. Those now-charged ions serve as nuclei for the vapor, which condenses into droplets that reveal the path of the particle. The characteristics of the trails are distinct to the type of decay particle that created them. In fact, both the positron and muon were first discovered in cloud chambers!

by any chance could you do a lil tutorial/process of how you draw limbs in different poses? esp. legs/thighs, your legs always look so jaunty and charming i love it but i never know what to, ,, ,,, do with mine, like where to put them so

Okay! I’m going to try to answer this best I can, but before I do, please remember I am just a humble animation student and by no means a professional artist or a seasoned expert, so this might not be the correct way to do things or be extremely accurate. This is just how I do it, and a couple tips I’ve picked up from teachers at school.

First of all, getting familiar with the anatomy of legs helps a lot! (I know this is the dreaded answer to every art question) I don’t know too much about the muscles of the legs other than the basics, so I don’t talk about them here because I don’t want to look like an idiot. They’re very worth studying though, especially the muscles that form the inside of the thigh and back of the calf.

Those are some leg studies I did from life in class last year, with the key parts labelled.

Chances are you’ve tried to draw legs and??

Unless you’re going for a certain style, legs that look like straight tubes or 90 degree angles are gonna look a bit weird.

As you can see with the life drawings above, legs have certain natural curves and rhythms to them! None of the bones in the legs are straight or tubular, so your legs should not be either.

Sorry for the really mediocre pelvis it’s not my strong suit oh god. It’s easy to characterize the legs as something like this:

Remembering that the knee is a hinge joint and that it has a sort of curved offset from the upper leg to the lower leg really helps.

So when you keep that offset in mind and apply some curves over the muscle and fat layered on top of those BEAUTIFULLY RHYTHMIC bones, you get dynamic flow in your legs. The hip (trochanter), kneecap (patella) and ankle (fibula/tibia malleolus) are good landmarks to keep in mind.

So by applying some curves, you get a softer/more dynamic/rhythmic feel to the legs that makes your figure look a lot less static even if they are standing entirely still. It’s also worth noting most people shift their weight onto one hip or another, position their feet weirdly, etc etc.

Hope that helps!


oof, this took a while. 

I’m not so good at comics but I was high-key inspired by @cerasi-nalamine‘s fic, “Make My Body Say” which I could go on and on about. My favorite thing about the fic, though, is how much subtlety gets packed into Monoma and Shinsou’s communication, like in their first conversation that I tried to draw here.

anonymous asked:

You know, I can EASILY imagine Nightwing becoming an Avenger???

Imagin the dynamic of DC and Marvel combining, my friend. 

Now I’m not saying the Justice League and Avengers need to become one team, but what if they worked together from time to time like the Avengers do with the X-men, a sort of partnership where they share information and help each other when necessary. 

But…but, the kids, well they don’t see the need for segregation. 

  • Peter and Dick hit it off on a joint mission over in Europe, they were both some of the youngest in hero-work and they seemed to have a lot in common. 
  • Both Iron Man and Batman weren’t too happy about the relationship because neither of them liked each other very much and they didn’t want their prodigies to associate with one another. 
  • Like that was gonna stop Dick and Peter in the slightest. 
  • There were fewer child-heroes at the time, so Dick and Peter got pretty close. Dick would end up at the Avengers Tower, and Peter at the Watchtower. 
  • And damn it, Tony really didn’t want to like this Robin boy…but he’s a great kid and everyone at the Tower has fallen in love with him…freakin traitors. 
  • Bruce won’t admit it, but this Peter boy has been really good for Dick, and they get along in both aspects of their lives. Diana and Clark were right…damn it. 
  • Clint and Dick bond over their old circus days. 
    Dick decides that Thor feels safe just like Clark does. 
    Natasha shows him even more defensive moves. 
    And meeting Captain America was almost as nerve-wracking as meeting Superman for the first time.
  • Peter and Barry hit it off, both a bit nerdy and hyper. 
    Diana is wonderful and Peter loves her with all of his heart. 
    Captain Marvel will do just about anything with Peter which he loves.
    And meeting Superman was almost as nerve-wracking as meeting Captain America for the first time. 
  • After about a year other younger heroes start showing up- Kid Flash, Human Torch, Raven, Beast Boy, Nova, ect. And they form a sort of team, The Young Titans. 
  • At first, the adults aren’t very happy with the idea, but the teenagers are persistent. 
  • And that is how by the time Tim Drake becomes Robin and Miles Morales becomes Spider-Man the dozens of teenage heroes are sprinkled around, from the Watchtower, to the Baxter Building, to the Avengers Compound. 
  • It’s a little crazy, having three different generations of heroes and different teams all mixing together, but somehow it works. 

Flow Visualizations

Spread across the world are a legion facilities that allow the creation of artificial oceans ( wave tanks ) which are used for experimenting with surface waves. From testing simple parts for behavior to comprehension of complex flow phenomenon in oceans and seas, wave tanks are freaking awesome!

And how they work is simple:

At one end of the tank an actuator ( those giant hands that are moving in unison ) generates waves; the other end usually has a wave-absorbing surface.

Pretty cool eh?

Finally got all of these together for my first little tutorial/walkthrough! Hope it’s helpful or entertaining for you people. :D I apologize for the length. I really just wanted to include each step.

So for almost all of my fusion art I use my Samsung Tab A with S pen and the Premium version of Art Flow for android. This can be done with most digital art programs and pen tablets though. :)

After I open my template I’ll begin doing a rough sketch of the pokemon on a new layer. I usually do a second darker sketch to refine the shapes a little bit more, and once I’m happy with that I move onto the line art.

I generally do the lineart with a hard round brush with size dynamics on and flow dynamic off which allows me to get good line variation. The brush is usually set around 11-15 px for the majority of the lines in the picture and usually 6 px for small details like the spots. There really is no special trick to how I do the lineart. I just go over the lines of the sketch in a new layer. For this particular pokemon I opted for a dark purple for the lines. I do this with some and not with others. It just gives it a softer look.

For the colouring I use a hard round brush. In this case I used one with size and flow dynamics off to get the smooth lines. In some of my others I turn flow dynamics on to achieve more blended shading. On a new layer I lay down the darkest or middle shade of the color and then layer on the lighter color.I don’t focus on staying in the lines as much as I do making sure the shading and colors inside the line looks correct. Once it is to my liking I clean up around the edges. I did this with all of the different coloured parts of the pokemon. each different color is done on a different layer. Once they are all complete I merge the color layers together.

Usually at this point it’s done, but this one I needed to add the ghosty part. I added the color over the feet and ghost limbs and played around with the layer settings. I believe I settled on overlay with the opacity reduced a little bit.

That’s pretty much it. It’s a fairly simple process. :) These usually take anywhere from 45 minutes to an hour and a half. I’ll be happy to answer any questions you might have just send over a message! Happy training !

If you want to see more posts like this in the future shoot me a message! I love hearing from you guys and would love to know what you want to see more of! :D I’ll be posting some of your requests soon, so stay tuned.

The Houses + Water


- A hot-water bath at the end of a long day
- Filling scent of rain on pavement or grass
- Fish, life forms living in aquatic habitats
- Enduring the rain if it means training/working harder


- Noise and intensity of pouring rain
- Ferociousness of crashing waves
- Clapping and laughter of a brook on stones
- Rain-bathing for fun despite all the reasons not to


- Water so clear it’s hardly visible
- Glassy lakes and bodies of water
- Smooth, mirror-like reflections
- Cool sips of water in between reading


- Swift, dynamic flow of a river
- Smooth gliding of water when swimming laps
- Trail of waves and foam when a boat speeds on water
- Movement and a glint in the darkness of deep water

ok but conversations with other people with adhd can be so freeing because ok, it won’t go anywhere and the topic will swerve randomly about 3000 times by the time the conversation is done, but there isn’t that stress of having to explain yourself each time you do a triple back flip in the conversation because the other person has also just randomly done a double somersault and doesn’t consider your divergence rude and somehow, even though you’re not even talking about the same thing, you manage to have three parallel conversations at the same time and understand each other without anyone getting frustrated.

So today was very much an “organized chaos” kind of day, and I loved it!! I really have to remember that all the posturing and neatness really isn’t what drives me and compels me to work, but rather it’s the actual work, done without filter or restraint, that I enjoy. I did a lot more significant work than I have in the past, and have a fair amount of confidence about the questions that I’ve been doing, since they’re going not super smoothly, but okay, and since they’re the first set of questions I’ve started, that’s perfectly fine! I worked on molecular reaction dynamics and flow chemistry, two of my more neglected subjects, so doing well on them feels great!

Anyways, I’m just really happy because I enjoyed working again. It’s a heady feeling, and one that I forget as soon as it fades. I really need to remember these study highs, and figure out how to work towards them. 

Often our atmosphere’s transparency masks the beautiful flows around us. This spectacular image shows a flight landing in Munich just after sunrise. Low-hanging clouds get sliced by the airplane’s passage and curl into its wake. The swirls are a result of the plane’s wingtip vortices, which wrap from the high-pressure underside of the wing toward the low-pressure upperside. The vortices stretch behind in the plane’s wake, creating turbulence that can be dangerous to following planes. In fact, these vortices are a major determining factor in the frequency of take-off and landing on a given runway. The larger a plane, the larger its wingtip vortices and the more time it takes for the turbulence of its passage to dissipate to a safe level for the next aircraft. (Image credit: T.

A computational paradigm

I was posed a question by an anonymous follower whether the following animation could be easily simulated on a computer. 

In today’s world, lots of research are being aided by using numerical methods. But it is quintessential to note that computational methods alone are not enough to dictate behavior of the natural world. It is with the amalgamation of experiments that it’s beauty exemplifies.

The butterfly effect

One of the many reasons its hard to predict behavior ( say the weather for instance ) is primarily because of the errors that are induced whilst recording it. 

And these errors evolve with time. Let’s take the trivial example of a double pendulum.

Notice how a slight variation in initial angle with horizontal axis of the blue pendulum causes a huge aberration in the result.

Flow past a cylinder

When experiments are carried out under controlled conditions, it is possible to observe and simulate phenomenon.

But like it was pointed out before,the simulation per se is proportional to the accuracy of the instruments used to make the measurements themselves.

So, yeah it is possible to simulate a system such as the one asked, considering crucial boundary conditions are known to us with considerable precision.

And as the complexity of the problem evolves, the computation time and power required also increases exponentially.

Thanks for asking, Have a great day!
