Also, Pythagoras was ~2500 years ago, before this thing.

Exactly, by the time this book existed 2100 years ago, the idea should have been traveling all over the place anyway. It's not like ancient civilizations were not connected at all.

Yes, people travelled a lot, specially merchants, that is also how Alexandria got many of its manuscripts.

The biggest difference was that nothing was assured about the safety of the travel.

Couldn't have said it better myself. I think about this stuff a lot, how much ancient and modern overlap, how much Eastern and western overlap, yet how people still want to divide everything. "The intuitive mind is a sacred gift and the rational mind is a faithful servant. We have created a society that honors the servant and has forgotten the gift." - Albert Einstein "The people in the Indian countryside don’t use t…

These divisions are very important. As long as mystical beliefs towards Eastern thought are used to cause real harm through herbal remedies and supplements, the public must be taught to give it less importance. Among critical thinkers, it is valuable to look for similarities in scientific histories.

anecdotal but had chronic sinusitis , allopathy mentioned only surgery as last option and that would also comeback after 5 to 6 years added sleep apnea. 3 months of regular Ayurveda and 12 days intense treatment. No issues now and very happy.

The GP is talking about the straight-faced lie that the PRC peddles in international circles that Taiwan is a province of the mainland government. It is the international equivalent of putting their hands on their ears and shouting "LA LA LA I CAN'T HEAR YOU!", and about as legitimate as Mexico's claim to Texas.

I've ended dates over this with Chinese girls. Inevitably they condescend to me about how "I'm just an American" that "can't understand the complicated situation," but that I should rest assured that "Taiwan is not a country, it is a Chinese province." Never mind the fact that I lived there, documented the sunflower protests, speak the language... As opposed to these girls that hadn't even visited the nation. Because…

I've just told older Chinese that the Taiwanese don't want to be a part of China and they tend to give it another thought.

You have not addressed my counter-argument. I'm not interested in defending "meat-based diets". I'm simply attacking your pseudo-medicine. > We have a society whose delusions cause diseases and destruction around the world. If I was wrong, there wouldn't be so many brilliant scientists, doctors, artists, and entrepreneurs on this same train of thought. Argumentum ad populum. > Yoga, meditation, plant-based diet have…

"Your pseudo-medicine"? lol. I never claimed anything as mine and last I checked Indians are very involved in the medical field. I'm not interested in discussing this with you, I have work to do. Things don't have to be this or that, they can be both. You obviously are looking for an argument because you missed my original points in the original comment. You obviously don't know your Bay Area history. ;)

"Your" as in "the one you brought up".

What does history or the Bay Area have to do with this discussion?

Last I checked homeopathy was western. i think your bias towards eastern medicine would be better founded if you were to say faith healing rather than eastern. Within eastern medicine one also finds people who used early forms of experimentation to derive working cures. Examples of working medical cures include boswellia used to treat bursitis, artemisin used to treat malaria. Also both Chinese and Indians had developed anaesthetic before Europeans. Similarly the procedure of rhinoplasty was developed in India. When the British came in western surgeons studied the technique and took it back to Europe. In fact hygiene was a critical part of the ayurvedic surgeons life well before Europeans realized the importance of hygiene in surgery. Of course there are a lot bogus stuff in eastern cures as well but in the west you have stuff like homeopathy. I think the key take away is that you cannot divide by east and west. We are after all human and each culture has their own contribution to the face of the earth.

Big Pharm and meat-based diet do a lot more harm to the entire biosphere and individuals than Ayurvedic medicine and yoga. Don't even get me started. I don't know much about Eastern medicine outside of India to be honest. One exception: Chinese people buy tiger bone Viagra, elephant tusk art, rhino horn something, and shark fin soup. I was born Hindu but became closer to Buddhist as I learned more about the scientifi…

Meat is unarguably bad, but the pharmaceuticals industry is the closest thing we have to a miracle factory. It has spared us from the miseries of polio, tuberculosis, smallpox, AIDS, surgery without anaesthetic and a thousand other horrors. Diseases that were once death sentences are now treatable with medications that cost pennies. Countless millions of lives have been saved by vaccination. Ayurvedic medicine clearl…

Not all ayurvedic medicine require heavy metals. There are herbs like boswellia (now also an allopathic drug) that genuinely do what they are supposed to do. Ayurveda, prevented black death in India. Granted there is a lot of bs out there that gets passed of but there are parts that do work. Distilling these parts is important. I think the lack of quality control in eastern medicine is what has given it a bad name. Granted we don't have antibiotics or anti cancer drugs but there were surgical procedures like rhinoplasty that were successfully carried out. Of course any medicine that is 2000 years old is going to be nowhere near what modern medicine is because we have had 2000 years to evolve it. Reason why easterners set store by it is it provided a bit more protection than what the doctors of medieval Europe could do. 1000years is a long time and lots changes, sadly eastern medicine didn't.

From what I understand, the Chinese had often recorded many facts about nature and mathematics very early and accurately. However they never really created much laws. Laws of nature was a western invention. E.g. they observed accurately planetary movements, but never attempted to formulate the laws governing those movements. That sort of thinking was crucial for scientific thinking.

Maybe true. The emphasis was on calculations. For example, there was a heliocentric model in India [1], which was too complicated to come from a "simple" mechanical model, but was quite accurate. But I think we should not be too eager to jump on to "science is only from laws" bandwagon. Courses on the philosophy of science take this dogma to absurd extremes, ignoring how current science is often done. There is enough…

Nice answer, but you eliminated the chance of a reasoned disagreement when you mentioned racism, especially when you created a strawman out of what they said.

"medieval Arab scientists" Ibn_al-Haytham was one of the inventors of the "scientific method". https://en.wikipedia.org/wiki/Ibn_al-Haytham

At least as far as is quoted on that Wikipedia article, he gives a description of basic rigor, not the scientific method.

Exercise in dealing with such "Exhibit A"'s: > Pythagoras' school provided the earliest documented proof of the theorem, but the result was possibly known as early as 3000 BC. Actually there is no known evidence Pythagoras or his school had any relation to the theorem. Much of it is word-of-mouth legend (and even then not particularly informative). It's amusing when the same people accept legends from Europe as canon…

You basically prove my point.

Your "proof" is some admirer claiming this guy discovered it [1] ? You realize, even if this were true, he'd (atleast) be third in the game. Also where pray tell me where is this glorious "proof" you were bandying about earlier ?

"Legend", you might want to look up the word. Or may be words are not quite for the big-mouthed ? ggrks man!

It must be clarified that mainland of China is also part of ROC according to ROC government[1]. In fact, the mainland and taiwan are in war, just like the Union and Confederacy in American civil war, even if there is not military conflicts right now. More interestingly, ROC actually claims larger territory than PRC (for example, part of Mongolia). It is ROC's constitution, not PRC's government, demands taiwan is part…

It would be rather peculiar if during the American Civil War the Confederates had retreated to something like Cuba and remained there to this day.

There's a community of Confederate descendants in Brazil. Most of them have assimilated but a few live in ancestral lands. There's an annual festival and everything.

https://en.wikipedia.org/wiki/Confederados https://www.vice.com/en_us/article/welcome-to-americana-braz...

There were also settlements in Belize and Mexico apparently. None of them lay claim to being independent nations and owning mainland US though.

The ROC as I see it retreated into an enclave of the former whole China and was never fully vanquished from Chinese land. So it's really more like if the Union stopped fighting after the Confederacy was defeated in all but one breakaway state. Even more accurately, since the PRC were the rebels, it'd be like the Confederates took over all the Union states except, say, Pennsylvania and then the war came to a halt. The Pennsylvania redoubt of the US would still be the US and may or may not make claims to the rest of the formerly united United States.

But what do I know about the situation? I'm just an American.
