no science teacher would ever say that.

Light travels in a straight line, plenty of crystals, linear erosion, many trees evolved to be as straight as possible...

and to be esoteric, every object path, even when gravity affects them (they travel in a perfectly straight line, but it is spacetime that is curved).

Careful with those absolute statements there buddy. I was told the same by a teacher, who challenged the class to come up with natural examples of either straight lines or perfect circles. He talked about how such things cannot exist because at high enough resolution/magnification there will always be interruptions.

Your own example of light traveling in straight lines doesn't account for the fact that photons are waves and absolutely do not travel in straight lines.

What about the fact that light bends around corners? Notably the interference pattern when shining light through a slit?

Ah, sorry for the confusion, I was referring to the single-slit experiment, I wasn't giving light a choice.

I don’t think that’s right because they are affected by gravity, even if ever so slightly

But isn't the gravity bending the space, so the light itself is travelling straight but seems curved to the observer?

Hmm, I’m not actually sure. Are we also ignoring refraction and reflection because the path is straight between those? If we’re talking discrete photons, you may be correct about each segment in its path being perfectly straight, but I’m not a theoretical physicist.

gravity isn't a force, it's the curvature of space-time itself.

light follows a perfectly straight line through vacuum. the space itself isn't straight.

like drawing a straight line on a flat paper, if you roll the paper, that line is still straight within it's medium.

Newtonian gravity has been replaced by General relativity, and has been proven to be the correct model (at least more correct than Newtonian gravity).

It travels in a straight line, just not in every dimension. Look at a waveform from above, it's a straight line.

Oh sure, bring evidence into it 🙄 lol. Um, how about sound waves?

2
sh.itjust.works

Sound waves are compressive waves, they radiate spherically (in principle, turbulence in the medium is going to make them slightly irregular)

2

Photons are both particles and waves, not only waves (that's because of the wave-particle duality discovered by/after Einstein's theories).

I work in public education. That's a pretty innocuous statement compared to some of the shit I've heard. Some teachers get so complacent in their lessons that they forget to apply it in their critical-thinking. Then, they have some crazy logical lapse, say something ridiculous out loud, and then some other kid from that class repeats that same shit to their own students when they grow up. These are mistakes that could easily be rectified with an apology or deliberate correction, but teachers are pushed so hard to prioritize being an authority figure that they sometimes forget to just be a teacher.

We can say that spatially, the summation of the photons movement is linear, but everything in the universe is waves and curves and we all know that to be true

if by straight you mean a perfect eucledian line, then there's no such thing as a perfect line in nature or reality.

as that might violate the Eisenberg Uncertainty principle. because if I know two points position or or if I know the direction and one point I'll know the position and direction of every point.

but then that's too esoteric.

You are clearly full of shit and have no idea what you're talking about, and your flip-flopping between positions

it's a meme channel, it's a stupid question, you get stupid answers.

I'm not putting my name in a paper saying definitely of straight exist in nature.

lemmy.world

If straight didn't exist in nature, it would just be gays and nothing would ever procreate.

2

Memes like this are so dumb. Laugh tracks for the internet.

4

It's useful as a navigational aid, if you're lost in the woods keeping an eye open for straight lines, especially horizontal, is a good way of finding man made structures and potentially a way out. Beyond that, on a micro scale nature loves perfect geometry.

4

Yeah, it's a very stupid concept made into a very stupid meme to make dumb people feel dopamine over the concept of scientists being allegedly dumber than them.

I really hate our species sometimes.

Worked as a physicist for 30 years, nobody talks like that. Everyone else in the room is to smart, and will slap you down for using absolutes.

would it be more grammatically correct if he said "with enough derogation"?

2

Yes, but I think that playing with the grammar is part of the joke, as if derogatory is quantifiable.

You didn't notice they used to but meant too?

Anyway they said they worked as a physicist not a linguist

Think you'd rather catch an art teacher saying that than a scientist tbh.

Most scientists won't say that there are no straight lines in nature, it's so obviously and provably wrong. I think it's more of a thing philosophically said when talking about how modern life is so different and unnatural compared to the lives of ancient people or animals.

I wonder if there's any animals who see crystals in nature and think "wow that's a really cool rock".

Birds definitely think this. My local Magpies have definitely attempted bribery with cool rocks and shiny discarded human objects

Tbh, I've only ever heard it when talking about camouflage. And tbf in that context it is somewhat true, you're harder to see if you break up those straight lines.

what is 'natural' life, being a sustenance farmer, and dying of starvation if you have a bad harvest?

Noobnarskireply
lemmy.world

Agriculture is already somewhat unnatural, so I guess a "natural" life would be hunter gatherers.

Are you trying to say that we don't follow the laws of nature? That our activities are supernatural?

I'd say this device I hold in my hands is the natural result of a social species who gained enough intelligence to mostly master their environment enough to spread globally, but still has the social need to stay connected to the tribe wherever they are.

1

Somewhat yes, nature usually tries to adapt to the environment, we are adapting the environment to us.

I haven't seen any other animal building roads and factories and cities.

2
lemmy.world

oh I see, so if you aren't a roving band of stone age people, then it's unnatural?

and are these societies also matriarchal or something too, because you know the patriarchy is unnatural as well?

0

Kind of, humans were hunter gatherers for so long that we evolved to be good at it, so I guess that's what would be natural for us.

Agriculture and our current life hasn't been around long enough for us to properly adapt to it.

I have no idea if those societies were patriarchal or matriarchal, I would imagine both happened or maybe even some sort of equality, if you want to know more about this go ask an expert in the field.

But in the end I don't care what you do, I just continued your argument.

Straight line and sharp corners in almost all crystals.

Nice eg. in Ireland

No need to go that far, I have one set of sharp corners sitting right on my lap. Also help, I'm trapped. :(

Your lap has been chosen! You cannot move until you are allowed to move.

And this is why absolute statements are generally bad arguments. It only takes one example to disprove them.

The dual is kinda the exact opposite, by definition. From an orthogonal perspective, cube is the wrongest possible word.
