Request for elucidation on claims about Islamic technological superiority

I met someone called SipahiWarrior123 on a German history forum, he has proven himself particularly by a display of profound knowledge on archeology of America as well as culture and mythology of Native Americans. Despite his expertise, he sometimes makes some doubtable claims, like the origin of the Native Americans from shipwrecked Turks, could you give evidence for or against the following claims or put them in a historical context.

1.) Knighthood originated from Islamic countries.

2.) There was technology inside the watches made by Muslims, which are being used in modern aviation and space travel.

3.) The ship type in which Columbus sailed to the Americas was adopted by the Spanish from an Arabic vessel.

4.) When black powder was adopted from the Chinese, it had no much use for firearms. It was not until Muslims developed 27 of the 29 different black powder types and therefore improved it, that it could be applied for military purpose.

5.) Although the irrigation systems of the Muslims were hundreds of years old, they were technologically modern until the 20th century.

6.) Muslims invented torpedoes.

7.) The Muslims invented siege weapons, comparable to modern tanks, wherein they were safe from stones, arrows and flammable pitch.

8.) The Osman had the best artillery.

9.) The impact of the Osman cannon balls are comparable to the impact of modern 120mm tank cannon, even though weighting only 1-3 Kg.

10.) At the time of the besiege of Constantinopel, the Muslim Osman had the biggest cannon ever built, it could fire a cannon ball of 600 Kg weight.

11.) The Muslims were leading in Medicine, while the Christian Europeans only got from them medical books which have been already outdated for 800 years.

12.) It has been discovered, that Galileo and DaVinci didn't invent anything themselves, they only translated the Muslim sources containing the technologies wrongly claimed by them.

13.) At the time of peace negotiations between the Muslims and Europeans, a science centre was built in Sicily where the Muslims shared their knowledge, but the Church considered it devil's work.

14.) The tolerance of the Osman empire was the reason for its demise. They allowed non-muslims to take political posts and replaced the original muslim Sipahi with the mainly non-muslim Janitshars. This led to the undercut of the power and the Sultan became nothing but a Marionette of the Non-believers and therefore the Osman empire declined.

That's a lot of points, but I hope some of you can share their knowledge to give evidence for or against some of the claims or but them into a bigger context.

What was no-mans-land like between the Union capital in Washington, SC and the Confederate capital of Richmond, VA?

The distance is fairly small, given the size of the US at the time.

  • What were fortifications and defenses like?
  • Did people live in between the two capitals? Were there settlements or towns?
  • How often did efforts take place to infiltrate or assault an opposing capital?

What affects did the Russian winter have on the Wehrmacht during Barbarossa and did it really destroy the offensive capabilities of the Germans as much as it is suggested?

When reading basic WW2 history, particularly in things like Middle and High school textbooks, I recall reading about how the Russian winter was one of the major reasons for the failure of the USSR. But is that really true? I know that the Russian winters are very cold, but did they really stop the German army in its tracks? If so, what was the problem? Lack of winter equipment? The inability of German tanks and vehicles to progress amongst the snow? And if the Russian winter wasn't as massive a factor in the German failure as suggested, how big was its impact?

I'm taking a class on the history of India and South Asia which has a large paper component. I'm going to do mine (hopefully) on the development and spread of Hinduism throughout Asia. That said, I will probably narrow it down as I work towards it, as I have several months. I would find it very helpful if people could recommend good overviews to get me started and a few more specific books for later on.

Public reactions to executions in the medieval period

Many modern depictions of executions show a cheering, laughing, jubilant crowd, who find pleasure and satisfaction from the execution. Is this depiction backed up by any historical evidence? Is this historical evidence trustworthy? (As in it isn't embellished by the executioners soas to make the person seem more hated than they actually were). Was it universal, or were they only really happy when killing people that everyone hated such as murderers and such?

Why is it that a powerful Russian state based out of Kiev never re-emerged after the collapse of the Mongol empire despite having been the most prominent Rus' city prior to that?

Also why it is that Kiev was sacked during the Mongol conquest and yet other large cities such as Moscow and Novgorod managed to escape that fate?

Why exactly did the gunpowder to cannonball weight ratio in cannons drop by the 18th century?

So, in some works i was browsing recently i found references to 17th century works showing preferred shot-powder ratios for cannons. Here is an one image (for ants) of a table showing it, but there are other instances where you can find similar tables and ratio values.

It seems the weight ratio of shot to powder weight for lower calibres was at that point 1:1 while for higher calibers it rarely goes below half a pound of powder for each pound of cannonball.
E.g. from the table above, the 32-pounder cannon takes 18lbs of powder - more then half its weight in powder. The 24 pounder cannon takes around 14lbs of powder. Smaller calibres are sometimes even have more powder then shot like Falcons of 2-3 pounders who take 3-4 lbs of powder

I then found by browsing the internets that by the 1700s gunners used to have a ratio that appears to be one third of powder to the weight of cannonball, sometimes even one fourth. Like this page gives examples of a 32pounder taking 10.6 lbs of powder and 24pounder taking 8lbs, while this page says later 24-pounders had used 6 pounds of powder. Obviously substantially lower amount of powder then previously.

As I see it, this change can be result of three things:

  1. better and stronger powder, either by using a new imporved formula or just better manufacturing process (but the little i looked I don't see anything indicating this. EDIT: also to clarify I am well familiar with corned gunwpoder. The case is, corning was in use since 16th century, so, on surface level, there shouldn't be much difference between cannons used in 1600s and 1700s as both should use corned gunwpoder. yet as shown above they use different powder ratio)
  2. better cannon and cannonball design and manufacturing, to have barrels and spherical shots closer to tolerances and with less imperfections for better flight

and finally

  1. just from experience or experimentation realizing they don't lose much by reducing the gunpowder weight, or perhaps it is even better, or deciding they can sacrifice range and power (which i am supposing come with more powder) and still do more then enough damage

What would be the real reason for this?

Was there an ideological "Communist Physics" advanced in countries like the USSR or China?

I know that Nazi Germany had a 'German Physics', which rejected certain advances, especially those considered "Jewish Physics", which of course meant a number of fairly important advances such as Einstein and relativity, but was there a similar movement in any Communist countries during the 20th century to reject "Capitalist Physics" and advance an ideological pseudoscience within the field?

What accident happened in 1937 that caused the Soviet government to execute 72 railway officials?

I was reading an article from the the always-fun Douglas Museum of Unusual Locomotives, which ended with this quote:

I feel compelled at this point to recount an event which may give some flavour of railway operations in Soviet Russia. In March 1937 a railway accident occurred in Siberia; the details of the event are so far obscure, and may always remain so, but what is known is that 72 railway officials were held responsible and all were executed. As Peter Semmens put it: "One's mind boggles at trying to imagine the circumstances whereby that number of individuals could have actually had a hand in causing an accident."

Does anyone know what this accident was? Were there any other incidences (aside from the purges of army officers) of massacres of a specific professional group perpetrated by Stalin?

Thanks!

What was the long term plan of the plotters behind the 1991 coup attempt in Moscow once they had seized power?

I've read much about the preparations for the coup and how it unfolded, but very little on what would have followed once it had been successful. It's quite interesting, as the coup leaders would have had to deal with a variety of problems such a ethnic conflicts, a collapsing economic system that they would have struggled to fix, and a restive population that rejected their communist ideology whole-heartedly and would certainly reject them. I've been reading a lot about the collapse of the soviet union as until recently I thought it was mostly peaceful and didn't realise the number deaths involved. Thanks in advance

What consequences did Reagan's huge tax cuts have? Positive or negative?

I remeber learning in high school about reaganomics and his big cuts on taxes, especially for the wealthiest. Republicans adore him and most (such as hannity, just heard him say this on his show) say it created thousands of jobs, led to actually having more money to spend and all that. Democrats hate him and say he led to massive debt and the future bankruptcy of social security. In a neutral, non party-affiliated point of view, an economic pov perhaps, were reaganomics postive or negative for the US economy? What long term and short term consequences did they have?

Can someone help me track down this online source regarding Confederate justifications for seceding from the Union?

Hi all,

I hope this doesn't violate the rules of the subreddit, as I know this isn't a direct question, but I am looking for help from good historians for a source I once came across in this subreddit. I will try to describe it best I can.

I remember seeing it in a discussion about the Confederate states' reasons for secession. Basically it was a table of each state and their own independent declarations of secession. More importantly, it highlighted the specific bits where slavery was explicitly mentioned as a reason for secession, helping to support the notion that the Civil War was about slavery. The source was online (a website somewhere, not a journal or book).

If you're familiar with this source, or something similar, please provide it. Thank you.

Why do some historians completely dismiss the Iliad and Homeric epics as having any historical basis?

If the Trojan War happened it would have occurred in about 1200 BC which would only place it about 400 or 450 years before it was written down by Homer in the 8th century. That’s not very long at all. That’s only about the distance from us to Hernan Cortes or Henry VIII which we still clearly “remember” as a society and no one questions that the Romans had a roughly accurate recollection of their early history hundreds of years before it was written down. Even the Old Testament of the Bible is generally accepted as having some historical basis.

Why then do I often read historians who seem totally convinced that even the rough outline of the Iliad as documenting a long and costly war between the Mycenaeans and Trojans is not “historical evidence” that it happened? The Homeric epics seem like such a vast and complex and specific collection of stories (even to the point of listing a bunch of specific genealogies) that I don’t see how they could have simply come from nothing.
