Wrong. The Arab slave trade [1] exceeded the Western one both in scale [2] and in cruelty [3].

I fully agree with your assessment of the reaction (or lack thereof, and its reasons) to 9/11 by the GWB administration. It is well supported by the testimony of Richard Clarke [1] and by the investigations of senator Bob Graham [2] [3] so I don't understand why your comment gets flagged.

My point was limited in scope to the 9/11 attack itself. I think terrorism on that scale can be classified as assymetric warfare.

Warfare predates nation states. Today, most of the world is parceled into nation states. But violent non-state actors never ceased to exist. And therefore we shouldn't limit our definition of warfare only to war between nation states.

I think the idea of "asymmetric warfare" is well established and it fits totally your description.

https://en.wikipedia.org/wiki/Asymmetric_warfare

Sure, there will always be people who think this not "real" war. But that's an irrelevant classification detail to the belligerents or the people caught up in the collateral damage.

bergoid··on Google Engineers Refused to Build Security Tool to Win Military Contracts
Agreed.

It's not too much of a stretch to describe 9/11 as an act of war.

Something similar is happening in Europe. The golden jackal [1], a close relative to the coyote, is expanding its range northward and westward from the Eastern Mediterranean [2]. They are breeding now in Austria [3] and recently an animal was spotted by a camera trap in the Netherlands [4].

A unit of "Moors". Again, Mediterranean looking North Africans. Despite the misleading title.

Of course not. The evidence is so thin it wasn't even up for useful scholarly debate.

> Beard is an expert on the history of the Roman Empire, and says that this is not a misrepresentation.

Her academic credentials are the very reason why she got criticized for what she said. Saying that the BBC school video is accurate is an extraordinary claim. And as a historian you might want to back that up with some evidence.

> She wrote a good article about it here: > https://www.the-tls.co.uk/roman-britain-black-white/

In which she dwells on twitter bullying and provides zero evidence for her claims.

> We have no reliable evidence regarding what proportion of Roman Britain was "black". We have good historical evidence that there were Romans present in Britain who we'd these days describe as black (e.g. an Ethiopian soldier garrisoning Hadrian's wall).

That "evidence" consist of one fleeting mention in a biography about Septimius Severus.

> For 101 reasons, the genetic evidence is not very informative, and certainly can't be used to justify that claim that Africans were a "statistically insignificant subgroup"

The lack of evidence (genetic or historical) puts an upper bound on the proportion of subsaharan Africans in Roman Britain that is several orders of magnitude lower than the BBC animated cartoon suggests.

> As Beard points out, even Norman DNA is not very well represented in the modern population, and we know for sure that plenty of Normans came over as a result of the Norman invasion.

For the presence of the Normans there is plenty of historical evidence. For the presence of subsaharan Africans there is just about nothing. So we should stick to the null hypothesis.

> Taleb isn't painting himself in a very flattering light with these attacks. They're very weird and bitter.

This is his default style as a polemicist and it distracts indeed from the points he is trying to make.

> And I can't tell what his actual point is!

The first 3 bullet points are his actual message. The rest is a reaction to some preceding drama on twitter.

His point is basically that Africans were a statistically insignificant subgroup among Romans in Brittain, and by adding them so prominently in a short animated cartoon for school children (who hardly know anything about antiquity) the BBC is performing historical revisionism.

He also casts doubt on the assumption that these Africans were black, pointing out that Northern Africa was inhabited by Berbers and Phoenicians.

> He furiously complains that the BBC and Mary Beard are "bullshitters" but I can't figure out exactly what corrections he wants made.

He wants scientific rigor to prevail over political correctness.

> These laws not only existed, they where far more stringent, prosecution far easier and the punishment far more severe. Try going back then and discussing the king/queen in a negative way.

True.

Because the subject of his book wasn't covered by these laws.

Neither did Damore. He still got fired.

These HR policies are a sign of the times. The fashion of suppressing rational speech & thought in a misguided attempt to "protect" the minority-du-jour will eventually creep upwards into the laws of countries, as has already happened in Canada:

> "Any communication which is threatening or abusive, and is intended to harass, alarm, or distress someone is forbidden"

Prohibitions like this one are overly broad and smother a lot of legitimate discussion. Exceptions to free speech used to be limited to things like:

* Don't yell "fire" in a crowded theater.

* Don't call for violence.

If we broaden the scope to any speech someone, somewhere might take offense to, then we can no longer have much diversity of thought in public debates.

If these kind of "hate speech" laws existed in England in the 19th century, Charles Darwin would possibly never have published the book "Descent of Man", because saying "You and I both descend from animals" was a very demeaning thing to say to most people at the time, and therefore could have landed him in court. The very idea of biological evolution is still offensive to a lot of people today, BTW.

A stark warning that this concern is not a sterile theoretical exercise came in August this year, when James Damore was fired from Google: https://en.wikipedia.org/wiki/Google%27s_Ideological_Echo_Ch...

So a company that champions and celebrates science to the outside world (like in their many doodles about scientists) and that has control over much of today's human communication, believes at the same time that it is a thoughtcrime to cite the scientific consensus about something as basic as biological differences between men and women.

The Orwellian implications of these definitions are hair-raising. This turns crime into something that is in the eye of the beholder and lies the burden of proof upon the accused.
bergoid··on Asteroid Mining Is Our Best Hope for Colonizing Mars
What advantage does living in the Martian underground have compared to living in a free flying space colony somewhere in the asteroid belt?

With the latter arrangement you have lots of minable resources at hand, only a small delta-v away from you. Ik you are ok with long delivery times, transporting them around doesn't cost you much energy.

Whereas on Mars, everything is much more energy-intensive, both mining raw materials and moving them through your industrial processing chain.

Space-based manufacturing is still an alien concept to us and while it comes with its own challenges, the vacuum and zero-gravity of space offers a lot of advantages too:

bergoid··on Don’t Fall for Babylonian Trigonometry Hype
In mathematics education, I always disliked the way inifinity is shoehorned into the different sets of numbers and treated as "just another number", so that you can write shorthands like: 1/∞=0, instead of the more accurate ∀ε>0, ∃c>0: x>c ⇒ 1/x<ε

Infinity is not a number. It's a limit.

Treating it as a number only confuses real understanding of it.

I think what turned off a lot of people is the transition made by opinion makers from the straight and falsifiable hypothesis "Global Warming" towards the weaselly worded "Climate Change".

Wording matters when it comes to mass communication. Words that were bold and scientific have been replaced by words that are indistinguishable from politics.

> I'm not sure what to put this down to. I usually use terms like feminism and political correctness.

This is sometimes called "cultural marxism". It is in my opinion the dominant ideology that permeates our thinking, our language and our behavior nowadays. That's why it is so hard to put our finger on it. We are like a group of goldfish discussing the concept of "water". Dr. Jordan Peterson of the University of Toronto does a great job at explaining how emancipation movements that were born with the best of intentions can transition gradually into tyranny. Though he uses just the word "marxism".

Of course there's also the fable "Animal Farm" by George Orwell which masterfully describes the cycle of emancipation from tyranny to a new form of tyranny.

bergoid··on Some Funny Things Happened on the Way to the Moon (2002)
A treasure trove of great anecdotes.

Just one example:

A few weeks before the launch, the Navigator Command Module Pilot, Jim Lovell, spent a few hours practicing on the earth-horizon sextant simulator at MIT. He consistently identified the “horizon” about 20 miles above the real horizon. Great! Jim Lovell could be calibrated and his bias number loaded in the flight computer.

In the same vein as this article, I am always deeply moved watching Dr. William Widnall's lecture on Apollo's guidance, navigation, and control:
