THIS CROW FUCKING UNDERSTANDS WATER DISPLACEMENT. WHY THE FUCK DO I HAVE TO BE TOLD EVERY YEAR BY A TEACHER HOW WATER DISPLACEMENT WORKS. DO THEY THINK I’M LESS INTELLIGENT THAN A FUCKING CROW? FUCKING DONE.


Crows discovered the principle of displacement in the third century BC, when the philosopher Awkimedes, upon noticing the level of his bird bath rose in proportion with the amount of his body that was submerged, reportedly exclaimed “EURECAW!” and flew through the streets of Athens shouting his discovery.

Science, then, is not like the onion in the often used analogy of stripping away layer after layer to get at some core, central, fundamental truth. Rather it’s like the magic well: no matter how many buckets of water you remove, there’s always another one to be had. Or even better, it’s like the widening ripples on the surface of a pond, the ever larger circumference in touch with more and more of what’s outside the circle, the unknown. This growing forefront is where science occurs… It is a mistake to bob around in the circle of facts instead of riding the wave to the great expanse lying outside the circle.

Stuart Firestein, from Ignorance: How It Drives Science

I was reminded of this quote, which sums up the driving force of the scientific process better than just about anything I’ve ever read, today after watching the latest Vlogbrothers video, in which Hank Green channels his inner Socrates:

"I know one thing, that I know nothing."

Watch Hank admit to being a towering mountain of ignorance (something we should all admit) below…

HOW NOT TO DRAW ARCHERY: AN ART TUTORIAL.

eschergirls:

badarcherart:

katieispainting:

DISCLAIMER: I was going to make this “how to draw archery”, but that would probably have taken the rest of my life. This is all stuff I’ve learned from practicing archery in the past, and the tips I’ve given should translate to many, if not all styles of archery. If you take issue with any of the information given here please contact me, as I’m aware I’m not an expert!

Okay, I’ve seen too many bad drawings of archery online. Most of the time I can overlook it, but I’ve made this guide to address drawings where a) the character would hurt/maim themselves if they shot like that, or b) if you tried to shoot like that, the arrow would just make a sad trajectory to the ground, the aerodynamic equivalent of a “WAH-WAH” on a trumpet.

With this in mind:

POINT ONE: WHY IS YOUR ARM LIKE THAT

If successful archery is about one thing, it is about consistency - being able to make your body take exactly the same stance over and over and over again. Your body is a key part of the weapon, and just as you wouldn’t want a gun that had components that wobbled and shifted, you don’t want your body to.

With this in mind, characters shooting, particularly at full draw (this is when the arm pulling the string is stretched all the way back), should have the arm that is holding the bow straight. Not locked - I’ll get into that - but straight. A straight arm is easy to replicate - a bent arm could be at a different angle each time. Simple as that.

image

POINT TWO: DON’T SHOOT YOUR TIT OFF

See this diagram

image

the dotted line is the path the string will take. The string is extremely tight - it has to be for the bow to work. It will therefore move extremely fast. Do you want any part of your body to be in the way of that.

image

if you have any part of your body (elbows and breasts/pectoral muscles tend to be the worst offenders) in the line of the string, they will get hit. And this will hurt. A LOT. Google “archery bruise” to see how. Yikes. Furthermore, if your arm or chest gets in the way, it’ll knock the arrow off course, and in addition to having sliced your nipple off you’ll have missed your shot too. So KEEP STUFF OUT OF THE PATH OF THE STRING.

side note: this is where the myth of amazons chopping their boobs off came from. Also, why archers sometimes wear chest-guards - this looks like a one-cupped unisex bra. Stylish. Also why archers often wear protective gear called a bracer. This goes on the tender inside of the arm and wrist that might get clipped by the string, not the outside that is nowhere near it.

image

POINT THREE: WHAT ARE YOU DOING WITH YOUR FINGERS STOP THAT

Okay I keep seeing this

image

Having the fingers clasping the arrow like this makes it highly likely that the pressure from them will send the arrow off-course.

Many modern bows have an arrow rest so you needn’t rest the arrow on your hand at all. If that isn’t the case, it works better to rest the arrow on the first knuckle of the index finger (where it meets the hand). If it’s just being used as a platform, the finger shouldn’t be able to exert enough pressure to make the shot go all over the place. Also you won’t end up shredding your fingers with the fletchings.

image

Talking of that…

POINT FOUR: DON’T SLICE YOUR FINGERS OFF

remember what I said earlier about how incredibly taut bowstrings are

imagine pulling that back with your soft fleshy fingers

it is basically like cheesewire through…soft fleshy fingers.

Use protection. Illustrated below are the tab and archery glove, or just go to google or something, stop the madness.

image

POINT FIVE: PHYSICS DOESN’T WORK LIKE THAT

A strung bow is taut. The body of the bow is pulled by the (very tight) string, making a D shape. An unstrung bow will be straighter.

The tension in the string means a string should always be a straight line. If the bow is drawn, it’s two straight lines. 

image

image

If there is any curve in the string, the arrow will probably fall limply to the floor.

ALSO. When the string is drawn back, it exerts more pressure on the bow, creating that really exaggerated curve. This is where the power comes from. (I think. I am not physics). Basically, if you’re drawing a character at full draw, the string should be straight and the bow should be curved. If the opposite is true something very wrong has happened and you should be sad.

image


OKAY! I hope this has been helpful, if you have any questions or concerns let me know. And if in doubt, doctor google will help you - look at olympic or professional archers, and see how they’re standing and how their bows behave.

GOOD LUCK DRAWING!

Very important!

As a note, number one can sometimes be correct if you don’t have an armguard, but you only bend it just enough that the string won’t his your arm and give you rope-burn. And you really shouldn’t be shooting without safety gear, anyway.

Since archery shows up an inordinate amount on this blog, I thought this tutorial was relevant and people might find it useful. :)

One thing I want to point out-it is very possible to shoot without a tab/glove. It hurts, but it’s possible, and you won’t immediately shred your fingers.
