Question to our resident physicist about that first one: Is that really true? Do idealized waves have the shape of a cycloid?

I love these.

I feel like this is less "how the world works" and more "some almost entirely unexplained videos of stuff working"

#1 could be looping perfectly but it's not

What is this sorcery? It loops perfectly in the album itself, but not when I check it out when hovering over the #1 link in your comment...

#10 seems wrong. Atria don't leak into ventricles as they fill, unless you've got a valvular defect.
GoldTeef4ErrBody
And sorry they do, the job of the atria is literally to fill the ventricles
JMegadethJ
Yes but not at the same time they themselves are being filled. Watch the animation closer to see what darklordpotter is referencing.
wizdum
I'm assuming goldteef is a dentist ;)
CertifiedAgreer
And the flaps only close due when the ventricles contract right?
GoldTeef4ErrBody
Yes because of blood pressure and why high/low blood pressure can be so bad for you

I think it's more to show the mechanism and relationship between sinoatrial node, atrioventricular node and purkinje fibres

It's a representation of light waves and their frequencies

No, its about music and rhythm and octaves and stuff something like a 3 to 2 ratio will align every 6 cycles

I wonder if that person will go the "I was being sarcastic" route?

I mean they were obviously being sarcastic. Whether they knew what it was or not is something completely different

I actually had no idea what #14 was representing, so I assumed it was just dots and boxes walking and singing along.

#8 Intel has never heard of Beowulf clusters I guess. Or even better: the 25-GPU cluster. Imagine a beowulf cluster of 25-GPU clusters? Rekt

Mind you, they are probably talking about their lowest-end product currently still in production. GPU > CPU for calculations.

What's happening in #12 ?
PancakeFaker
Applying labels for something similiar to a Pringles can.
perrenekton
Just ... What is #1 ?
addiced
It shows how a single water molecule moves in the context of the whole wave.
memequisition
It's how the moon affects tides.
perrenekton
Oooooh neat
Neptuneflyer
No, I'm pretty sure it's just showing how individual particles move in a wave, and has nothing to do with the moon.
DrSparken
It is, and it's a simplified model since waves usually aren't that precise and tidy, but is the most dominant mode of movement.
MisterR4Z0R
It's depicting the movement of water.

It seems like most places won't let your password be longer than 8 characters!
Trecares
Or more annoyingly, accept 20+ length on registration, but their login only handles 15 or so it fails and you have to reset the password.

What is going on in #6?
vman2000
I've seen videos of DNA replication, and I always wonder what is causing all those proteins and little parts to move around like that.
whenyourescrewinotherwomenthinkofme
1/2 It has to do with attraction of different proteins and chemical messengers to eachother due to certain affinities determined by shape,
whenyourescrewinotherwomenthinkofme
2/2 size, and charge and the ensuing reactions
MechaNinja
DNA replication or something.
TheCarolingian
It doesn't look like mitochondria. Which is the powerhouse of the cell.
Trexcalibur
I wasn't taught how to look after my health, but mitochondria is the powerhouse of the cell!
MohammedMandourah24
DNA replication
SaltyInternetPirate
I'd be wondering, too, if I hadn't seen it before in a video. As others have pointed-out, it's the copying of DNA molecules.
blzrdphoto
What's cray cray is that video is real time how fast it actually happens in your cells. Amazing!

Glad you asked I was wondering too. DNA replication: https://www.youtube.com/watch?v=F4epSBaPtN0

Darkfoxblade
Weird though . Got a root canal a couple years back and they put the cap or whatever on the tooth but it broke leaving the fillings exposed.
MarisaTomei
Was it a temporary filling? Or did they give you a new post, core and then a porcelain cap?
Darkfoxblade
Can't remember but probably temporary
OpticRocky
Just got a root canal, they give me a temporary crown a couple weeks after the initial root canal and had me come back two weeks later for
OpticRocky
A permanent crown, what broke was probably a temporary cap.
Darkfoxblade
As a person with trypophobia. Feeling the fillings was a living hell. Trypophobia as far as plants? Don't care. In the body though? Hell nah
TheWeeShmeal
#3 is the Falkirk Wheel. It's basically a giant canal lock. It works as a giant wheel to move boats to a different height.
Sakkura
#6 is DNA replication. Helicase splits the double helix, then one strand is easily replicated at the bottom. 1/2
Sakkura
The other loops because DNA can only be replicated in one direction (and the two strands in a double helix run in opposite directions) 2/2

I'm glad someone explained this. I was gonna step in otherwise. Take your updoot sir and/or madam!

Leading and lagging strand...
krewann
I got an explanation of the first one. Which is actually a cut off of something crazy cool. So it's a sort of simulation of water 1/
krewann
Particles movement in waves. So the thing here is, that all particles are actually just moving in circles around the same center. This is 2/
krewann
Opposed to the normal belief that water moves, like when a wave comes in, it consists of 'new' water.
krewann
http://faculty.gvsu.edu/videticp/waves.html this is a short scientific article about it.. 4/4

Well, the hexagon has the longest legs, so it takes the biggest steps.
CanadianFurr
I think it has something to do with colour wavelength.

The password one bothers me because no matter how true it might be those numbers are just baffling
Fitzman
It's exponential bruh
RickieBaker
XKCD has a really good comic on passwords: https://xkcd.com/936/
gaidinbdj
They're also way off. And don't solve the underlying problem of memorizing complex passwords.
[deleted]
[deleted]
gaidinbdj
Something like "Compl3xity" would take minutes, not years.
CanadianFurr
not necessarily. if it was "Complexity", then yes, it would take a matter of minutes, if not seconds, to crack it using a dictioary attack.
BecozImBatman
Numbers will depend on many factors... So this might b a possibility
cantfindmelol
Why do you think the numbers are way off?
gaidinbdj
A password like "Coml3xity" would cracked in a matter of minutes, not years. After basic dictionary cracks, simple substitutions are tried.
cantfindmelol
Yes... But I would assume they're showing numbers for brute forcing at a certain processor speed so their numbers aren't really 'way off'...
OneGoogleSearchAway
When doing pure brute force(no rainbow tables/wordlists) with no masking(assumptions based on common passwords), the figures seem realistic.
CanadianFurr
I read that 8 characters (using upper/lowercase, numbers and symbols) would take a couple days. I guess it's gotten a lot faster now.
OneGoogleSearchAway
Yeah 8 chars you could crack with a decent gpu and hashcatOCL at home. The 14 char DoD minimum length w/ complexity increases exponentially

#9 - that projectile won't fly well, all deformed like that.
Mavgurian

Radiorifle
I think it is just the 'cutout' section of the barrel making it look odd when loaded in. Thought the same thing initially.

yeah... I was (failing at) making a joke. sigh. :~)

Yeeaahh.. Saw your other comment and figured I would just leave this one here to help other dumb people like me XD
WisconsinCentral2714
what do you mean? naval shells fly pretty damn well from a 16" gun, and that is basically their shape
onefaller
the "cutaway" makes it look like the shell get mushed.

ok, I see it now
delpharseven
Full explanation of #8: https://www.grc.com/haystack.htm Read it all carefully, especially the part about commonly used passwords.
JackSkellington59
Doot for later use
Wurstinator
The important part is the "final note". Complexity is just as important as length.
delpharseven
Complexity protects you from the initial dictionary attack, length protects you from the latter brute force guessing attack.
c0dengo
It doesn't say that. The whole point of that article is that length is more important than complexity. The final note says not to put dots..
ViperSoldier
One suggestion I have heard is to use 5 or 6 words that are not very frequent as a password
ViperSoldier
Not exactly. Most password cracking tools will already make known substitutions (0 for o). You want a longer password, not a complex one
Mavgurian
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
ViperSoldier
That would probably work, a brute force attack would try every character in every place, so it would take a while to crack
Mavgurian
A system vulnerable to brute force attacks - no forced delay that gets longer, no lock after x failed tries etc. - is not safe anyway.
Wurstinator
DogDogDogDogDogDogDogDogDog. This is a long password but can be cracked rather fast, as its effective length is only 9 words.
ViperSoldier
Right, but who is going to guess that your password is the word dog 9 times over instead of a 10 character password?
Wurstinator
Password cracking using dictionaries software will do that.
DrSparken
It's an unusual password to assume; if you don't assume repetition, but know it's a sequence of up to 9 common words, that's still about 1/
DrSparken
ten million times harder to guess than four less common random words. (Assuming "simple" is dictionary size 1000, less common is a 2/

#14 So THAT'S how the world works.
ConstantTacos
I think it's about colour wavelengths
Remainder
harmonics, yeah
csillagvihar
I think it's supposed to somehow visualize how all colors of light move the same speed but with different wavelengths or something.
Smudgee
I'm not sure if it's just because of my job, but it looks like it could be a representation of subdivisions in rhythm.
xKeiserSozex
For some reason I thought it was depiction of how sound waves work to make a chord.
CthulhusGreasyBallsack
it's all of these, nature's laws span many different schools of though.
xKeiserSozex
Very true!
DaweDoo
Yes, as infrared has a long wavelength and ultraviolet a short
djsdkdjsk
visible is orange right? whats green is green microwave?
MeowsInSpanish
All colours we can see are in the visible spectrum. Microwave doesn't have an associated colour, bc its wavelenght is above the visible.
djsdkdjsk
i mean in the animation, i mean so the orange line is visible and the green is microwave? am i right? i know visible has all colors we 1/2
krewann
I think he/she meant in the animation :))

#8 I changed my password to 'mypenis' but it wasn't long enough. So I tried 'mypeniswhenerect' but it wasn't hard enough.
