complex numbers are just numbers in a plane instead of a line. saying you don’t believe in i is like saying you don’t believe in “up”

For that matter, the real numbers are fake as fuck. “Ah yes, let’s just throw in uncountably many non-computable numbers.” They have played us for absolute fools.

Yeah TREE(3) is so big, how can you possibly know that there are that many evens??

cpw,

The set of all rational numbers has zero size in the real numbers. And yet, they’re fucking dense, meaning you can find a rational arbitrarily close to any real number. I mean, what the fuck?

joneskind,

The fact that you can’t solve any real life electro-magnetism problem without them kinda put an end to that complex shaming nonsense.

Yet there are still people to miss the absolute poetry of their story.

In 1545, an Italian genius called Gerolamo Cardano was pissed he couldn’t solve square root of negative number.

« Fine! I’ll make it myself » he said, before sending everyone to hell.

He then invented an imaginary number i whose square would be -1.

It wasn’t until centuries later that another famous genius named Leonhard Euler found a practical use of those numbers.

Without those numbers we would still be living like 1800´s peons.

Iirc, it was while trying to solve cubic polynomials, that he found out that accepting the existence of sqrt(-1) let him solve them.

Mathematics is the only branch of science that will continue long after the universe ends.:-)

DarkenLM,

Pretty sure that when humanity dies, math dies with it, and the universe won't give two fucks about it and continue on it's merry way.

morrowind,
@morrowind@lemmy.ml avatar

Think e meant in the sense that math is true regardless of the universe (or some people believe)

MossyFeathers,

Math is literally made up. There is no physical basis for math. Math is just another language used to describe things. The universe doesn’t care whether there’s “2 particles” or “1 particle and another particle” or “1 particle + 1 particle”. It doesn’t make these distinctions. Math only exists as long as there is an intelligent species which uses it. If there are no intelligent brains capable of using math and with a knowledge that it exists, math stops existing.

anzich,

Technically true but most math is motivated by nature

girl, (edited )

Except there is math in nature, such as fractals, the Fibonacci sequence, and the wave behavior or sound and light. Sure nature doesn’t have any awareness of doing math, but it is there. Not all math is made up just for our understanding.

MossyFeathers,

That’s kinda the point though. Math is a language inspired by reality. It describes the logical relationships between things in an abstract format. Physical sciences like physics or chemistry build off it by adding rules and units to more accurately describe or predict real-world relationships, but at the end of the day, it’s all made up. Nature isn’t doing math to create a fractal any more than you’re doing math when you move your fingers or toes. Math doesn’t create a fractal, it describes it! You can then use that description to create a fractal, but the fractal isn’t math.

frunch,

This conversation reminds me of the first couple times i surfed Reddit over a decade ago. It was so cool to be in a place where intelligent and interesting discussion was happening… Wish i could contribute something useful to it, but i just want to thank you all for carrying that kind of energy into the '20s 🥂

MonkderZweite, (edited )

And it has an awkward syntax. That i can have this opinion at all is already proof of it being made up. Which is applied logic btw.

blanketswithsmallpox,

Math isn’t really made up. It’s an innate property of the universe at minimum being interpreted by humans as numbers and equations.

It can also literally be what the universe is made of.

PBS Spacetime www.youtube.com/watch?v=F__elfR3w8c

MonkderZweite,

You mean logic. Math is describing this in formulas. Some even make up nonsense with formulas. Wasn’t there a scientific ‘proof of god’ with flawed logic years ago?

MossyFeathers,

I like the extended version, though I’m almost certain I saw an even more expanded version somewhere, though I haven’t been able to find it again.

Pulptastic,

That’s tough to swallow. Philosophy almost belongs at both ends.

MossyFeathers,

No, I mean, I remember there being a further expanded version that adds more steps between social sciences and philosophy. I haven’t been able to find it though.

BluJay320, in Remove all barriers in the way of science
@BluJay320@lemmy.blahaj.zone avatar

Well, I wouldn’t say all barriers…

Ethical matters, such as experimentation on animals and especially humans, need barriers in place. We don’t need another Josef Mengele

But I agree with the intended sentiment

Tar_alcaran,

Also, we need barriers related to quality, otherwise you get shit like Andrew Wakefield trying to sell his alternative vaccine, and in the process creating the modern antivax movement

ourplnt.com/earth-without-water/

The original is a exaggerated estimate (projection) based on a assumed sphere, probably WGS84, because a lot of the global satellite data is formatted as such.

en.wikipedia.org/wiki/List_of_map_projections?wpr…

Eheran,

“reality” as in extremely exaggerated deviations from the ellipsoid. Otherwise it would just look like a smooth sphere. Earth has 12’700 km diameter. From the shallowest point to mount everest are just about 20 km. That is a 0.15 % change. You would see nothing.

MoonManKipper,

Bang on, the Pacific is not 250 miles deep…

kn0wmad1c,
@kn0wmad1c@programming.dev avatar

To put in perspective how shallow a 0.15% change is, a dimple on a golf ball is roughly 4 times deeper than that (0.60% of a difference in depth).

Zoboomafoo,
@Zoboomafoo@lemmy.world avatar

“Smoother and rounder than a bowling ball” is my usual comparison

Eheran,

I think that would be too much. A bowling ball is really smooth. It would not roll as well with such deviations all over the place.

At a diameter of 22 cm, the roughness would have to be in the order of 0.3 mm, which would not just be visible due to the distorted reflections, it would even be audible while rolling.

nucleative,

Rodeo,

This is what happens when people have a basic knowledge of history and basic background knowledge of their field of expertise.

That’s not to minimize their intelligence and competence; that’s to say that it is expected that astronomers would know the names and histories of major nearby celestial bodies.

lemillionsocks, in linguistics
@lemillionsocks@beehaw.org avatar

I find people who actually study language are more tolerant toward different pronunciations and informal speech and colloquialisms and less likely to be grammar nazis.

SuiXi3D,
@SuiXi3D@kbin.social avatar

Probably because they understand that all language is made up and they all change constantly. There’s no hard and fast rules.

bdonvr,

Language science/grammar/etc are all just observations of a natural phenomena, they are not laws to dictate.

DroneRights,

Antitheism is colonial white people shit and it sucks

macaroni1556,

What do you mean?

DroneRights,

You know that joke atheists tell Christians where they say “We both agree that most gods don’t exist, I just believe in one less than you. You and I aren’t so different.”? Well, that joke is more accurate than the atheists realise. The monotheism of the pre-roman Christians and Jews is very different to the monotheism of today.

Ancient Christians and Jews believed in the gods of every culture, but they only worshipped one. That’s how every culture treated foreign gods, back then. The Romans transformed the world forever when they used religion as a tool of cultural genocide through syncretism. As Roman polytheism was replaced by Roman Christianity, it became the custom to deny the gods of foreign religions. This was a new thing, back then.

Anyone who studies history knows that Europeans have been copying Rome ever since Rome fell. The colonisers of the new worlds copied Roman techniques of cultural genocide, by denying not just the power or worthiness of indigenous gods, but their very existence.

White modern atheism exists in the wasteland left in the wake of Christianity. The difference between a Christian coloniser and a white antitheist is one god. That’s insignificant. The antitheists are simply carrying on the traditions of Christianity, rather than attempting to actually move beyond a roman Christian worldview and learn from the way human thought worked before Christian genocide.

weker01,

How does Islam fit into your frankly absurd worldview?

DroneRights,

My absurd worldview? I guess you think the Encyclopedia Brittanica is absurd too

www.britannica.com/summary/monotheism

The monotheism that characterizes Judaism began in ancient Israel with the adoption of Yahweh as the single object of worship and the rejection of the gods of other tribes and nations without, initially, denying their existence.

Oh, and Stanford

plato.stanford.edu/entries/monotheism/

Most mainstream Old Testament scholars believe that the religion of the early Israelites was neither monotheistic nor polytheistic but “monolatrous.” While the existence of other gods was not denied, Israel was to worship no god but Yahweh.

Maybe just read some encylopedias if you want to know more about the history of monotheism

weker01, (edited )

No they don’t claim antitheism is colonial white people stuff.

First your own cited sources contradict you: you said that ancient Christians believed also in other gods but ancient Judaism was before that. Also in those sources you find that this happend in ancient Israel.

I don’t think the people there would be described as white.

DroneRights,

You should try reading instead of skimming

weker01,

You should try discussing instead of resorting to ad hominem attacks.

Frankly you never stated how the behavior of Islam (that is also a monotheistic religion that denies all other gods) fits with the idea that antitheism is colonial white people stuff.

DroneRights,

Islam is a religion derived from and influenced by Christianity

pruwybn,

I think you meant estimable (worthy of great respect), not inestimable (too great to calculate), although I guess they both work.

Inestimable also means “of great value”
