A group of friends and I were chatting the other day about our “AH HA” moments. A shot where something clicked. I can clearly point out a few of these in my career, but this one comes to mind first. I was STRUGGLING with CG, big time. In fact before getting to Disney I had decided to give it up and try my hand at storyboarding. Then I was accepted into Talent Development as a CG Animator and decided to give it one last shot. I spent 6 months in Tal Dev and there were some clicks but I still had a hard time using the graph and a lot of the other tools. Here’s an embarrassing fact…I went through all of “Frozen” not knowing how to switch between IK & FK and not knowing what constraints were. I just brute force everything. A lot of frame by framing. After Frozen I was asked to work on a water projection show for Disneyland called World of Color. This is the shot. I Finally understood the graph and how to benefit from it. I had been using CG for about a year at this point and finally started to get comfortable with the tools. Which means, I started to enjoy the process more. All this to say, stick with it. Persistence and patience is key. We all learn at different paces, so just keep at it if you’re struggling and you’ll have your “clicks”. I still have them all the time, sometimes for a technical hurdle, sometimes in drawing, sometimes for body mechanics or animation principles. It means we’re growing, so keep at it!

Machines are admirable and tyrannize only with the user’s consent…. Where, then, is the enemy? Not where the machine gives relief from drudgery but where human judgment abdicates…. The smoothest machine-made product of the age is the organization man, for even the best organizing principle tends to corrupt, and the mechanical principle corrupts absolutely.

Introduction to Hegel’s “Force and the Understanding” - Reader’s Guide

Welcome to the most difficult section of Hegel’s Phenomenology of Spirit!

So you’re not alone in you’re confusion, most people find this section completely impenetrable, but I happen to have spent some time working on it and writing about it, so I can definitely help point you in the right direction.

So there’s no real way to explain this without interpreting every piece of this chapter line-by-line, but I can point you in the right direction as far as making sense of “what Hegel’s talking about” goes. He’s talking about Leibniz and Newton, mainly, but with a bunch of other physics thrown into the mix.


Before doing anything, it’s important to understand the results of the previous chapter. The previous chapter gave birth to the “Unconditioned Universal.” This represents the resolution of “being in-itself” with “being for-another,” basically Hegel’s answer to the Kantian thing in-itself. With the Unconditioned Universal, both the “untruth of the subject” (the falsification of reality through consciousness) and the “untruth of the object” (the thing in-itself that evades us) have been aufgehoben. So any claim we make about things for-us will also have to be shown to be in-itself, otherwise the chapter will fail, and we will return to the stage of Perception where we’re still not sure if we’re somehow falsifying the thing with our knowledge.

The chapter can roughly be divided into two sections. Like the previous chapters in the Phenomenology, the first part takes things as they are as objects and the second part examines the role of the subject.

1. Sections 132-141: Leibnizian Dynamics: Active and Passive Forces & Solicitation

“The fascination of the electro-magnetic theory of light, advanced by Maxwell and subsequently experimentally investigated by Hertz, was so great that even now, although controverted, the scientific minds are under its sway. This theory supposed the existence of a medium which was solid, yet permitted bodies to pass through it without resistance; tenuous beyond conception, and yet, according to some, one thousand times denser than platinum. According to our conceptions of mechanical principles and ages of experience, such a medium was absolutely impossible. Nevertheless, light was considered essentially a phenomenon bound up in that kind of a medium; namely, one capable of transmitting transverse vibrations like a solid.

“It is true that many scientific minds envisaged the theory of a gaseous ether, but it was rejected again and again because in such a medium longitudinal waves would be propagated with infinite velocity. Lord Kelvin conceived the so-called contractile ether, possessing properties which would result in a finite velocity of longitudinal waves. In 1885, however, an academic dissertation was published by Prof. De Volson Wood, an American, at a Hoboken institution, which dealt with a gaseous ether in which the elasticity, density and specific heat were determined with rare academic elegance. But, so far, everything pertaining to the subject was purely theoretical.”

“What, then, can light be if it is not a transverse vibration?

“I consider this extremely important. Light cannot be anything else but a longitudinal disturbance in the ether, involving alternate compressions and rarefactions. In other words, light can be nothing else than a sound wave in the ether.

“This appears clearly if it is first realized that, there being no Maxwellian ether, there can be no transverse oscillation in the medium.”

The Newtonian theory is in error, because it fails entirely in not being able to explain how a small candle can project particles with the same speed as the blazing sun, which has an immensely higher temperature. We have made sure by experiment that light propagates with the same velocity irrespective of the character of the source. Such constancy of velocity can only be explained by assuming that it is dependent solely on the physical properties of the medium, especially density and elastic force.”

Equation #11: Heisenberg’s Uncertainty Principle

Anyone who is not shocked by Quantum Mechanics has not quite understood it”-Niels Bohr

I agree Mr. Bohr, QM does blow your mind. The uncertainty principle is one of those things that prove that our perception of the world is limited. Anything in the universe can be both wave and particle at the same time and that puts a limit to how accurate our measurements can be.
What that means in our context is that, if you try to measure the velocity(or momentum) of a particle as well as its position at the same instant, you cannot have exact values of both. If you measure position accurately, the value of velocity will have some uncertainty associated with it and vice a versa. 

The reason we don’t observe this phenomenon in everyday life is is that the uncertainty values are very, very tiny. A person moving with a velocity of say, 5 km/hr (+or - 0.05 km/hr) and weighing 60 kg will have the uncertainty in position = 1.8 * 10^-35 meters! That’s smaller than the radius of an atomic nucleus. However, when you go into the realm of lightweight, superfast entities(like subatomic particles), the uncertainties get larger and can have a significant effect on the macroscopic properties of an object. 

The uncertainty principle applies to a number of pair of observables other than momentum and position. Most common example is that of energy-time which explains the working of Strong force, according to some theories.

It is important to understand that this fundamental limit is not due to experimental errors, rather a phenomenon of nature itself.

You cannot predict, even theoretically, the exact values of two so called “incompatible” quantities simultaneously.

why I can't count "The Day of The Doctor" as canon, explained with temporal mechanics

1. The Principle of Infinite Temporal Flux states that all of Time is constantly in motion, allowing for changes in the past to radically change the future.

2. The Principle of the Fixed Point in Time states that there are Fixed Points which, if changed, they will cause cataclysmic damage to the future and the fabric of reality itself.

3. Time is made up of particles called chronons.

3a. Time travel results in time travellers having artron energy in higher amounts than their species usually has artron energy.

4. The Principle of the Blinovitch Limitation Effect states two things: (a) that a time traveller cannot redo anything he/she/xe has already done and (b) a dangerous energy discharge will result if two temporal versions of the same person come into contact.

4a. This energy discharge is most likely related to the unbalanced amounts of artron energy in the two different temporal versions.

5. Because the regulatory force of the watchful Time Lords was gone, paradox monsters known as Reapers destroy anything contained within the radius of the paradox.

Once the Doctor left the point in the timeline where he puts Gallifrey in a Time Lock, he locked that event into place because you don’t get a redo (4). The changes have taken effect and cannot be changed by the same time traveller once you’ve “locked” them in (4). Change to the Time War’s end is cataclysmic (2), impossible (4), and would kill all of the Doctors (4) with an explosion of artron energy. And then the Reapers would show up and destroy everything else (5).

Other unnoticed violations of the Blinovitch Limitation Effect include Martha’s offhand comment about seeing the moon landing 4 times (“Blink”, Series 3, written by Moffat); the short Good Night” had Amy Pond giving her younger self an ice cream cone (written by Moffat); similarly, the shorts “Space” and “Time” feature no ill effects when Rory, Amy, and the Doctor come into contact with Rory, Amy, and the Doctor (written by Moffat). The last of these could be explained by the fact that it took place in the TARDIS, which apparently can sustain paradoxes.

anonymous asked:

The universe is super funky but do particles pop in and out of existence in empty space & if so how would that even work/ where would they originate & how would they dissipate?

They do! This is simply the strangeness of quantum mechanics. The uncertainty principle allows for weird, counter-intuitive phenomenon we just have to accept. Essentially, the uncertainty principle states we can never be 100% certain about exactly how much energy is contained within a given region of space. If particles didn’t randomly pop in and out of existence, then we could be 100% certain that the energy in a vacuum would be exactly zero, which is not allowed.

So, there isn’t an actual “mechanism” that causes particles to appear and vanish at random, it’s just a weird property space must have to preserve uncertainty. Thanks for asking!


White Dwarfs and Neutron Stars

What happens to a star after it dies depends entirely on the mass it contains. If the star has a low to medium mass (anything less than 8 solar masses) then at the end of its life it will transform into a white dwarf. If a star is massive (8-20 solar masses) then it will turn into a neutron star.

When a red giant starts to fuse helium to carbon and oxygen but lacks the mass to generate the core temperatures required to fuse carbon, an inert mass of carbon and oxygen will build up at the core. Towards the end of the stars nuclear fusion stage, it will shed its outer layers in the form of ionized gas forming a planetary nebula. The core that is left behind is the white dwarf typically about the size of earth. This is made up of electron degenerate matter which forms because the white dwarf lacks its previous ability to create an internal pressure meaning gravity squashes the mass much closer together. The reason this is happens is because under normal circumstances electrons with the same spin can’t occupy the same energy level, and there’s only two ways an electron can spin (this is known as the Pauli Exclusion Principle). In a normal gas this isn’t a problem because there aren’t enough electrons to fill the energy levels. In a “degenerate” gas however, all its energy levels filled. For a white dwarf to be forced smaller by gravity, it would have to make electrons go where they couldn’t go thus white dwarfs survive through quantum mechanical principles that prevent their collapse further. There are other unusual properties as well, white dwarfs with greater masses are actually smaller because gravity has to force the electrons closer together to maintain the outward pressure. However the limit to how much mass they can have is about 1.4 solar masses.

Neutron stars are incredibly dense (and one of my favourite things ever) with a typical one being about 20km and containing 1.4 solar masses. A teaspoon would weigh about a billion tonnes on a neutron star, that’s how dense they are. They are also composed entirely of neutrons as the force of gravity is so great that it has caused the electrons and protons to fuse into neutrons. The power from the resulting supernova that created the star causes it to spin up to 43,000 times a minute, gradually slowing over time. The neutron stars which are still spinning emit electromagnetic radiation that we can detect when it’s pointing towards earth (much like a lighthouse). These are known as pulsars. The magnetic axis of a pulsar is what determines the direction the beam will fire off in. However this is not necessarily the same as the rotational axis and this misalignment is what causes some to appear to pulse. There are currently three different types of pulsars that astronomers are aware of. The first is rotation powered pulsars which the radiation given off is caused by a slowing down of the rotation of the star. Accretion powered pulsars occur when the gravitational potential energy that falls onto the neutron star causes X-Ray’s that can be received from Earth. Finally there is magnetars where the radiation is caused by an extremely strong magnetic field losing energy.

Uncertainty principle - Why do we still pay fines then. Quantum mechanics

I’m gonna be a bit INTP and write about this quantum mechanics principle I found very interesting.

This principle says you can’t determine two properties (A and B) at the same time.

So, according to this, police can’t know my exact location (A) and velocity (B) in a certain moment.
Well, police can still detect it because that principle doesn’t have importance regarding radars. In fact, they can detect velocity with a precision of 0.5 m/s. Why it doesn’t matter? Because of this equation:

ΔR . ΔP ≥ h / 4π

ΔR is the variability of location detected by the radar, which is 1 meter. Aka: a radar can detect where I am with a precision of one meter more or one meter less than the one given and in any direction.

P is the multiplication of mass (in this case the car, 1 tn=1000kg) and the velocity. So ΔP = 1000kg . ΔV (v=velocity)

Therefore, if i want to calculate ΔV:

ΔV= h / 4π . 1000kg. 1m

h (Plank’s constant) is 6.62x10^-34 (freakin small number)
So ΔV=0.52x10^-31 m/s.

For the ΔV to matter it should be MUCH higher. That number represents the limit so if i had to rest my actual velocity minus this number 0.52x10^-31 m/s which is almost 0 the result would practically be the same as my actual velocity. So no matter the limit of the equation, it can’t save me from the police knowing my velocity.

Although it can’t help you for breaking the law it does have an importance on quantum level. And this is much more interesting. It’s impossible to know the exact location and moment of an electron at the same time because of the limit. But you can know the velocity and location independently. Now the laws of nature are taking place.

Joseph-Louis Lagrange, born on 25 January 1736, was an Italian Enlightenment Era mathematician and astronomer. He made significant contributions to the fields of analysis, number theory, and both classical and celestial mechanics.

Lagrange was one of the creators of the calculus of variations, deriving the Euler–Lagrange equations for extrema of functionals. He also extended the method to take into account possible constraints, arriving at the method of Lagrange multipliers. Lagrange invented the method of solving differential equations known as variation of parameters, applied differential calculus to the theory of probabilities and attained notable work on the solution of equations. He proved that every natural number is a sum of four squares. His treatise “Theorie des fonctions analytiques” laid some of the foundations of group theory, anticipating Galois. In calculus, Lagrange developed a novel approach to interpolation and Taylor series. He studied the three-body problem for the Earth, Sun and Moon (1764) and the movement of Jupiter’s satellites (1766), and in 1772 found the special-case solutions to this problem that yield what are now known as Lagrangian points. Also, he has transformed Newtonian mechanics into a branch of analysis, Lagrangian mechanics as it is now called, and presented the so-called mechanical “principles” as simple results of the variational calculus.

The Steven Universe “Opposites Attract” theory.

Alright guys and gals, I don’t know if anyone else has noted this pattern and seen the subtext- I don’t know if there has been anyone bigger or more important than myself who asserted this theory but I hope you will allot me a few moments of your time to, hopefully, blow your mind! I warn you, this theory will be talking primarily about the various ships within the Steven Universe series but all ships are respected and all ships are viable. This theory is simply an attempt to chart and predict the most likely romantic ships that will occur in SU- if any besides Ruby and Sapphire occur at all. If you are not caught up with SU up to the end of the Latest Stevenbomb episode “Log Date 7 15 2″ there will be spoilers and you have been warned!

Alright, so the basic premise of this theory for the shipping mechanic centers around one principle I’m more than sure you have heard once or twice in your lifetime

“Opposites attract”

Now before you grill me because this is way too simplistic to truly apply to any schema of life. I’m not talking about 100%, complete, night and day different people because their are limits to differences. When I think about opposites attract I don’t think night and day I think of a balance scale, both parties in the relationship bring different things to the table that total and balance out everything as a whole. The two sides can have similarities but it is not in their similarities that they find their love, it is in the way their differences counteract with each other and even each other out to make something better. Before talking about all of the possible ships this idea an theory could bring about, let me talk about all of the ships and pairings this principle is HEAVILY apparent in.

Ruby and Sapphire

Originally posted by qpoca

Now it might seem like I am contradicting myself when I said no night and day examples exist, but I still hold true to what I said because although these two are probably the most different individually in the series but complete opposites hardly. Sure she’s ice and she’s fire. She’s emotion driven and she’s logic driven but despite their differences they still hold key principles together that make this dynamic work, they both had the option to abandon the other at some point or give in to their homeworld’s culture etc, etc. Just because they formed this:

Does not mean that Sapphire had to save Ruby from being broken or that Ruby had to help Sapphire prior. They both genuinely care and have the capacity to operate beyond the norms of their homeworld culture because they are similar enough within core values, but different when painting a full picture. These two are sort of the mascots for my theory because they are a wonderful example of how two very different beings found something special in each other beyond what separates them and makes them different.

Can you guess the second pair I have in mind?

Greg and Rose

Now we move on to our second and so far only canonical couple in the series to date, Greg Universe and Rose Quartz!

Originally posted by songs-and-ships

Ah yes! The differences between a human man and a technically sexless (but not genderless) space rock lady who originally came to invade the planet- surely these two are like night and day right? Still not correct even though these two are a close second if not the number one most opposite pairing in the series or out of the possible pairings I will describe momentarily. Now, why are these two significant? Well not only do their two respective cultures put these two both literally and metaphorically worlds apart but their very existences are nearly polarizing. She is an ancient gem warrior who has been alive thousands of years and is still constantly fighting in order to protect those she loves and make them happy. Greg is an entertainer who aims to make people he cares about happy through his music, and for all intents and purposes he is a pacifist, he never solves his problems with fighting or really any form of violence as long as he can muster it- the only instance of this being ramming the Lapis clone of Steven as it was drowning Connie and Steven. Point being, Rose is a warrior and Greg is an entertainer. Rose is a gem and Greg is a human. Rose is not opposed to fighting to solve a problem and Greg is pretty much a pacifist but they are both genuine, compassionate beings who aim to make the people around them happy. The differences they share are what undoubtedly made this pairing so sweet and what finally made Rose actually fall in love with a human besides simply loving other humans like before. Rose saw something so much more different in Rose that she willingly gave up her physical form so she could share something special with Greg, Steven. 

Both of these pairings are different but it is because they are different that they found, for a lack of better phrasing, their better half. Now the real topic of discussion, how would this predict FUTURE pairings and what would those pairings be?

Pearlmethyst (PearlxAmethyst)

Originally posted by pearlmethystoftheday

I don’t think I need to even really discuss how these two are different. It seemed like for the greater part of Season 1 up until “On the Run” these two being at each other’s throats might as well have been as commonplace as the air we breathe. But I believe the main difference that destines these two for a possible future pairing is this poignant difference: Pearl is from homeworld where as Amethyst is an Earth born gem. Why is this different important, it directly reflects every other aspect of their personality and basically makes them who they are. The reason Amethyst is they way she is because she is the most human gem, so to speak where as Pearl is the most “gem” gem because she almost never indulges in human pleasures much unlike Amethyst who consistently indulges in them. So far, out of all of the possible pairing options, this paring is the closest to being canonical mostly based on my theory. Their differences are making the other not only closer, but it is making them into better more well adjusted people. Noticed how considerate and generally less obtuse but still very much herself Amethyst has been, all the way since “Reformed” really? Notice how calmed and generally more relaxed Pearl has been in recent times? I mean Pearl hardly freaked out when she thought one of homeworld’s leaders was about to learn everything about the CG’s and Earth when before it only took an infestation in Rose’s fountain to send her into a panic attack. These two have been subtly changing in ways that don’t compromise who they are while allowing Pearl and Amethyst to gain a sense of closeness to where they are able to form Opal ALMOST as seamlessly as Ruby and Sapphire form Garnet, which is incredible to note considering where they came from. These opposites in these two make the other a better person while still allowing the other to be themselves, they show that two different cultures and walks of life ( Homeworld and Earth) are able to be something greater. Pearlmethyst is the bridge between homeworld and Earth.

next on the list is Lapidot

Originally posted by timehuntress

Now, a lot of the criticism that this ship gets is that these two characters have never had any onscreen interaction so why on Earth are people shipping these two so intensely? Well, I agree these two have not shared much screen time, but just because they haven’t doesn’t mean they can’t and if you ask me- I believe their pairing is the most likely to occur withing canon because of the major difference that would bond these two in a unique way much like all of our other parings. The pairing of Lapidot would be the ship that connects the past and the future. lapis lazuli is clearly an old gem, much, much older than Peridot and possibly as old if not a little younger than the like of Rose Quartz, Ruby, Sapphire and Pearl. Lapis is old enough to know what and who the crystal gems are while Peridot is initially baffled by the CG’s, maybe having read the name in the long but in no way demonstrating any prior knowledge to having personally known or been involved in this conflict at all. Lapis Lazuli is utterly clueless about the future while Peridot is mostly unsure about the past. Lapis can’t connect wit the new homeworld and Peri can’t relate the much without it (initially). Once again, vastly different personality wise but one thing they share in common- they both know literally nothing about Earth or at least not anything about the Earth we have now. For lapis, Earth is more advanced, for Peri Earth is primitive but both are different and will be hard to understand for the other. I believe these two will find that their different approaches and perspectives how to approach their new, strange world will make it a hella ton easier for each other in the long run and in this they will find how truly much they care for each. I believe the ship Lapidot will be canonical because it will be the ship that bridges the differences between the future and the past.

Admittedly those two were the main two ships this is for, I mean Stevonnie (the ship not the fusion) is another potent example of my opposites attract theory because it is a much more powerful, and extreme example of bridging gem kind and human kind- which was Rose and Greg initially but now Steven and Connie took on the mantle. Jasper unfortunately doesn’t have a direct link opposite like the other three ships because although she varies from each gem mentioned, I don’t believe she varies in a way that is impactful or meaningful enough within the realms of my theory. Plus I don’t think Jasper could really let go in order to care for someone in that way. She is more of a warrior bond, protect you with muscle kind of deal. However in the spirit is letting Jasper be happy, I believe her warrior nature would be a great counter for Greg’s pacifist nature. So Gasper maybe fits. Like I said all ships are welcome and loved these two are just he ships I believe most likely to be canonical due to a pattern I’ve seen in the show. I’d be remissed not to mention two more ships honorary style: Amedot and Lapearl.

Amedot is good for a lot of reasons Pearlmethyst is, except with the added bonus of Amethyst being able to guide Peridot through earth culture and life on earth in the most earth way a gem can! I really love this ship and a main reason I ship Pearlmethyst just a little bit more is because if Amedot was cannon then Pearl and Lapis would not have anyone to connect to with in an incredible, meaningfully like all of the ones I mainly transcribed, though that makes it no less valid than any other ship!

Lapearl I like because it can offer an interesting dichotomy to the old Rose/Greg/Pearl triangle, instead make it Steven/lapis/Pearl. Lapis feels for Steven in a manner similar to pearl for Rose but Steven, like his mother, chooses the human over the gem. Pearl having been through this before is able to off Lapis the shoulder she never felt like she had. Although this dichotomy is interesting, it is not greatly significant or as impactful as many of the other ships I’ve discussed before because this doesn’t really off the characters to grow, instead it brings Pearl back into her past and Lapis only a small fraction of development I feel she would get from Lapidot.

A major theme in the show is the acceptance of everyone despite their differences. and I will go further to say that these differences are important because they allow all of us to be greater people in the end of the day!

End theory

Nerves move to avoid damage

New data presented by Marinko Rade in his doctoral thesis can help explain the insurgence of widespread syndromes such as Carpal Tunnel Syndrome or Sciatica. He showed that neural movements can be measured using non-invasive techniques, also applicable in diagnostics and rehabilitation planning.

For the results published as part of his thesis, he has been awarded the “Young Scientist Award 2013” by the Finnish Spine Society, and the “2014 Young Investigator Award” by the world top-rated scientific journal Spine.

Work or hobbies can put a strain on nerves

Daily motions can be extremely various in terms of movements of peripheral nerves. Office workers can be writing for hours on computer keyboards, repeatedly compressing the median nerve in its pathway into the carpal tunnel, but not all of them will develop carpal tunnel syndrome. Water polo and handball players are vulnerable for stretching of the median nerve around the glenohumeral joint and in front of the elbow during the preparation for a shoot, but not all of them will become symptomatic and develop peripheral neuritis. Auto mechanics are prone for compression of the median nerve in the carpal tunnel in a similar way as keyboard workers do but not all of them will eventually need medical help. Marinko Rade’s doctoral thesis helps us better understand the reasons behind all this.

Nerves move, this is why

It has been widely showed on cadavers that nerves move. But why should nerves move within the body in the first place? It is believed they move in order to avoid potentially harmful mechanical forces such as tension and compression. So nerves slide longitudinally to avoid tensile forces and transversally within our body to avoid compression. However, it has not been known whether the direction and magnitude of such movements can be measured and predicted in patients. Marinko Rade showed in his dissertation that neural movements can indeed be quantified and also predicted, and moreover, using non-invasive techniques.

His research offered new data on the subject, particularly in aspects that have not been studied before, namely spinal cord movement and muscular protective effects during limb movements that produce excursion of nerve tissues. Research on living patients now being possible, cadavers may be a thing of the past.

More individual rehabilitation planning

In the first part of his doctoral thesis Marinko Rade explored the use of magnetic resonance imaging to investigate the neural movements into the thoraco-lumbar vertebral canal of in-vivo and structurally intact asymptomatic human subjects. He showed that those movements can be predicted and used in clinical practice to perform diagnosis and plan a very specific rehabilitation process.

In the second part of his doctoral thesis he focused on electrophysiological methods to quantify the muscular reactions in response to neural stress following the hypothesis that the muscles may be reflexively activated in order to protect the peripheral nerves in the most logical way; by shortening their pathway and opposing the harmful body movement. From the results it seems that it is indeed like that.

“In order to explore the normal neural adaptation mechanisms, the principle of no-harm has to be respected, that is, the investigation methodologies have to be non-invasive,” Marinko Rade says.

He adds that the aim of his dissertation is not only to present plain data, but to try to shift the clinician’s concept of nerves passively enclosed in tunnels delimited by bones, ligaments and muscles,  to the concept of nerves sliding and moving freely in those tunnels in order to avoid potentially harmful mechanical forces as tension and compression arising from interfacing structures, and increase the awareness of the fact that those movements can be measured, understood, predicted and also possibly used at our advantage in our everyday clinical practice.

“It is theorized that the preservation of a free sliding of the neural structures in the anatomical tunnels might be the conditio sine qua non for maintaining an asymptomatic situation. If this will be achieved, then this thesis will have served its purpose.”

This is definitely not something I’d usually paint but the music is very inspired  by the sound of 80’s synth music which very often had covers with paintings of spaceships or other kinds of science fiction.
