NASA Tests Hypersonic Blackswift

dijkstra writes "Blackswift was previously rumored to be a super secret hypersonic scramjet-based aircraft co-named HTV-3X, essentially a 21st century version of the SR-71. Today NASA has unveiled the real Blackswift (video link), which uses pulse detonation engines (PDEs). A PDE is essentially a modern version of the old V-1 buzz bomb engine. This engine requires significantly fewer moving parts and achieves much higher efficiency than a turbofan, and is technically able to go hypersonic without any kind of 'dual-stage' engine."

I'm somewhat confused as to what has been "unveiled".
Everything I've read so far says that this plane is still in the "sketches and mock-ups" stage.

Though I guess someone found the time to do a slick render.
Maybe the PR push is an attempt to keep Congress from cutting their funding.

The alarming thing is not that Fox News readers do not reflect upon the standard of intelligence at Fox News Studios, rather, it reflects upon the intelligence of the American Public in general. After all, this is a free market, and Fox News is only delivering the quality that people are demanding in that free market.

From my extensive corporate background, I can tell you that if somebody that has been hired acts dumb, he's usually dumber than he seems; all a matter of cost efficiency, a smart guy acting dumb would cost between twice and three times as much, and you'd risk him saying clever things once in a while anyway.

I dunno though. I used to post on politics where people used to post things like

"Everything I needed to know about the Middle East I learned on 9/12 when I listed to Jackyl's song 'Open Invitation' and got drunk on Budweiser with my buddies"

(fuck yeah, BTW)

But when I went to meet up with some of them they were all expert internet trolls and quite well read. None of them would dream of drinking Budweiser or listening to Jackyl. All of them had gone to college.

And it's quite possible that Fox just exists to make liberals rage and conservatives laugh. The head of Fox said that the "Fair and balanced" slogan was adopted because "it drives liberals wild".

The fact is that liberals have control of the networks - I saw poll that showed essentially all journalists at CNN, ABC, CBS etc vote for the Democrats.

So a right wing troll minority network trolling the majority was pretty much inevitable.

Re:I feel dirty

[Anonymous Coward]

I don't think liberals would care if

1) They knew that it was an intentional troll
2) They were sure no-one (outside of a mental institution) was watching it and actually taking it seriously.

The problem with such trolling on such an epic scale is that America is a democracy (and has a democratic mindset) - so that people who believe trolls actually affect us at the polls, and in every other facet of public life that's based on democratic principles (from flooding various companies with angry calls, to NOT getting outraged when someone in a position of power abuses it - whatever that may be). This also applies to the "liberal media", but for whatever reason, Fox News seems to be by far the worst offender of fabricating bias, inappropriately inserting emotives, and misquoting science/facts to suit their own bias (maybe because there are more science factions/studies biased to liberal viewpoints, maybe because reality itself is liberal, who knows?).

Apart from anything, if people did believe even only half of what they saw, it's terrifying to think how much power the newsmedia holds. It's amazing to think that it's potentially several orders of magnitude more destructive than even the most dangerous illegal weapon someone could obtain - sure a bomb may kill a buildings' worth of people, but can it change an election?

Re:I feel dirty

[ppanon]

The fact is that liberals have control of the networks - I saw poll that showed essentially all journalists at CNN, ABC, CBS etc vote for the Democrats.

Uh, no it was that around 90% of journalists that make campaign contributions contribute to the Democrats. But the number of journalists making campaign contributions was around 10%. So you can only say for certain that <10% of those journalists support Democrats. The party orientation of those who donate doesn't necessarily match those who don't. I could conceive of a scenario where those who don't donate are greedy and figure they're sufficiently supporting the Republican party through biased news worth far in excess of the monetary contribution of their Democratic-donating counterparts. Not saying that's the case, just that the data that's available could be consistent with either scenario.

Now, most contemporary journalists are also pretty scientifically illiterate, which make them an easy target of ridicule in the technical community. And their understanding of economics and far too much else is often not much better. However, that Fox talking head in the linked video seems like a particularly egregious example. Fox News appears bad to anybody who isn't blind since they seem to insist on giving equal or more time to the emperor and his tailors than to the small child and his observations.

Nevertheless, you might also want to consider that many journalists get to see and hear about the raw information before it gets massaged by editorial boards that are selected by corporatist management. So when it comes to coming to conclusions that only require facts and common sense, not technical knowledge, like the general state of the country and how various political parties influence it, they're likely to be better informed than you.

In any other country there would be a real left wing and something close to your democrats or republicans as right wing or ultra right wing.

Bill Hemmer is probably one of the dumbest they've got too. Not all of them are quite so bad, but he is really a bubble headed empty suited talking head.

If I happen to have Fox on when Hemmer starts yapping, I change the channel. He is one of the most annoying talking heads on ANY network.

Re:I feel dirty

[DrLang21]

This assumes that the political/social interests and standards in the US match those of the rest of the world, which they most certainly do not. You do make a valid point though that the Democratic and Republicans parties are not nearly as different in practice as they would like us all to believe.

Re:I feel dirty

[Shihar]

It is all about context. When we say left and right on a US centric site (and yes, Slashdot has a disproportionate number of America readers), they are talking about the American system of politics. It is true that it is a large mistake to think that the American system has ANYTHING to do rest of the world's "left" and "right", but that doesn't mean that it isn't internally consistent.

The entire left/right scale is a tad silly simply because it stuffs a whole bunch of utterly unrelated ideals into a binary system. You can have a free market capitalist who believes in gay marriage, abortions, and a lack of sex and drug regulation. You can also have someone who advocates socialist economics want to outlaw those very same things.

Tossing American parties on a European left/right scale is pointless. The American right is absolutely nothing like the European right or ultra-right. The European ultra-right would likely be quickly slapped with a label of fascist or crazy ass ultra nationalist label in the US. The American right doesn't have the ultra-nationalistic tendencies that the European far right has. Le Penn and other such ultra-nationalist would get the cold shoulder in the US for their frantic obsession over immigration. Other European ultra-right parties would get the cold shoulder for being viewed as being far to socialistic in terms of economic issues.

My point? You are better off trying to understand parties, both in the US and Europe, as they are, not trying to slap them on a left-right scale. American and European parties don't belong on the same binary scale together. What makes Republican's "ultra right" in European eyes is that they are not left and not that they have any commonality to European ultra right parties.

If you desperately want to plot them on the same scale, I would suggest looking at the libertarians favorite scale, the two axis "social liberty" and "economic liberty" scale. The American right will appear in the right corner, the American left and European right in the center, the European left on the left, and the European ultra-right on the bottom.

Since you aren't from America, you might have a skewed view on how the cable networks operate here. Just about any cable channel can survive due to the channels being sold in packages, thus everyone gets a nickle, even if nobody is watching. Also, with such a diverse number of backgrounds and sheer magnitude of population, just about any network can get enough viewers to look popular.

What I find scary, other countries broadcast this same crap network to their citizens. If the average American hates Fox (just look at the thread or ask the next American you meet), why would anyone from another country even consider tuning in?

To clarify for those who don't know: Fox News is cable-only. It's not a broadcast channel, nor could it survive as one.

Re:I feel dirty

[ArcherB]

Those people will hire people who are likely to promote the same viewpoint.

They hire people who make them money. They are big business corporations, after all.

I would believe that if the "liberal" run networks had more viewers. But that's not the case. In cable news, Fox gets more viewers than all the other cable news networks combined. So, if their job were to get more viewers (and thus more money), then they would have followed Fox's example years ago.

Re:Air Force != NASA

Actually it's neither NASA, nor the Air Force developing this. It's a DARPA program and the Skunk Works is the primary contractor. The contract doesn't officially begin until September of this year. The footage shown in the video is also not real--artists conceptions at best. Furthermore, the vehicle doesn't employ pulsed detonation engines for hypersonic flight. The so-called NASA analyst in the video just saw a request for money in the 2009 budget, stole some artist conception used for market assist, and tried to put the pieces together--poorly I might add.

Fox's "America's Newsroom" shares a timeslot with shows like Good Morning America (ABC), Today (NBC), and The Early Show (CBS).

Islam was the pinnacle of science and technology (9-14th centuries) until the Ash'ari movement became popular.

Because that's the main demographic of morning shows like America's Newsroom.

http://en.wikipedia.org/wiki/Breakfast_television

Breakfast television programs normally feature regular news briefs and information reports on business and the stock market, and weather and commuter travel (traffic in North American usage)--particularly in the 'early half', when the bulk of the workforce demographic is still home. Later in the program, programming will shift to more homemaker-oriented entertainment programming, to reflect a dominantly female demographic.

Personally, I'd say it's somewhat insulting how the programming turns lightweight and airy once the menfolk have gone off to work, but that seems to be what the morning viewers are interested in, even accounting for their political/religious/philosophical bent.

So while it must feel nice to rant about Fox and the "segment of society that distrusts education, knowledge and science" which watches them, what you just saw is pretty much par for the course during the 9:00-10:59 AM time slot.

Re:Awful

[Jafafa Hots]

Bullshit. Yes scientists don't know everything, they're the first to admit that - which is why they search the truth and science progresses.

Whereas those who reject science say "science doesn't know everything" and so they reject science and instead embrace the thing that starts out with NO knowledge, insists it knows EVERYTHING, the ultimate truth, and thus makes no further effort to learn, makes no progress for centuries. Religion.

And its complete BULLSHIT that intellectuals have been behind the genocides and murders.

Intellectuals, scientists discovered evolution... and through sequencing the genome have discovered that there is NO SUCH THING AS RACE. Scientists have found that if you take a white frenchman, a black nigerian, and a white englishman, sequence their genes, you're just as likely to find that the frenchman is more closely related to the nigerian than the englishman as vice versa.

It's the anti-intellectuals who distorted this. Just like they do with their bible, they rejected the parts they didn't like (we came from apes) and distorted the parts the suited them (social darwinism.)

It's not SCIENCE that said that blacks were created inferior to whites, it's religion. It's not SCIENCE that divides people and tells the to slaughter the "others," it's religion.

Religion was behind the "blacks are inferior" thing, the preachers were preaching against interracial marriage, now they're preaching against gay marriage.

It's not scientists and intellectuals who are behind this "fight against islamofacism."

And ya know what Stalin and Hitler did with intellectuals? They KILLED them. Slaughtered them ny the thousands, felt they were a threat. (Which of course they were, a threat to fascism.)

Hitler used religion, and Stalin eliminated religion not to replace it with intellectualism (ever hear of Lysenko?) but rather to replace the power of religion with his own.

[Eponymous Bastard]

Notice that it's not just when the "menfolk" go to work. It's when working people go to work. The only ones left at home are pre-preschoolers and career housewives.

There are plenty of women who would be insulted by this talking down, but a large percentage of them go off to work too. Some are left at home, women who choose to take care of their family instead of a career, but I bet the morning crowd is dominated by non-college educated, artsy, low-ambition types.

So it's not necessarily sexism going on but a reflection of the demographics of the society.

Re:Could this be the Aurora

It might be. I seem to recall the aerospace media calling it Aurora. There were a number of sonic booms over the LA area that were attributed to it that weren't traced to known military planes. And I seem to recall the Brits took a picture of a pulse trail of something attributed to Aurora

It could easily be that Blackswift is the military name for Aurora. It would be kind of like the stealth 'fighter' from a number of years back. I believe it flew for about seven or eight years before the Air Force admitted that it existed. And the Air Force name for the project was definitely not what the aerospace media called it. (Nor was it shaped anything like the Revelle model that was created representing a stealth fighter.)

Not even in the same class as the SR-71

[paganizer]

now, don't get me wrong. this is a cool bird. but I wouldn't say it was cooler than the SR-71.

It's probably designed to be the replacement for the "blackstar" program, which doesn't exist, but is hands-down the very coolest thing out there, the only thing cooler would be a functioning Orion spacecraft.

But this looks like it might have the capability of taking the place of the blackstar "mothership", although I bet with less performance & payload; as this isn't designed to be a Mach 3+ cruise nuclear bomber, that's understandable. but those cold-war birds have got to be tired by now, and looking forward to retirement. i think one would look great in my driveway as a static display.

I do wonder what they are going to use to replace the orbital component, which was probably based on the X-20. Maybe a NASP? The X-43?

UFO over Yakima Wa. in the 90's

I always figured it was some spook project.

Build your own jet

[loic_2003]

The V1 flying bomb used a pulse jet engine rather than a pulse detonation engine - the difference being that a PDE burns at a supersonic rate whereas a regular PJ wouldn't be able to get to those speeds.

His website is here.

Let's put it like this

[Moraelin]

The difference is that they're very very different kinds of engines really. Sorta like the difference between a turbofan and a piston engine in an aircraft. Both suck in fuel and use a propeller to push the air towards the back, but they're very different engines anyway.

A scramjet is, sorta, an afterburner without the turbojet in front of it. Think just a de Laval nozzle, sorta, where the airplane's own speed shoves the air from the front, and you inject the fuel and light it in the back. It can only operate at hypersonic speeds, because it does need the air coming in really hard and fast, and it burns fuel continuously. There is no need for pulses or detonations.

A pulsejet, well, think a pipe with a valve in front. Sorta like this, with "front" being downwards:

|.|
|.|
|.|
|T|
+.+

The T is the valve.

Air comes in, you inject the fuel, and ignite it. The pressure closes the valve, so the only way the burnt gasses can go is backwards, pushing your aircraft forward. Then the pressure equalises, the valve opens again, and the cycle starts all over again.

This one can _only_ operate in pulses. On the up side, it can operate at subsonic speeds too. It's also a very simple and robust engine. The V1's pulsejet could be riddled with holes and still generate most of the thrust. The RAF found it easier to just tip it over, with the tip of the fighter's wing pushing the V1's wing upwards, than shoot them.

Downside, also generates massive vibrations. The buzz of the V1s could be heard from the ground. It's a bit like flying a jackhammer. Which is one reason it never got too popular for manned aircraft, or aircraft which were supposed to fly more than once.

Well, that's the simple explanation anyway. There are more modern designs which, for example, do away with the valve and essentially just choke the flow via a nozzle to achieve the same effect. But that's the general gist of it.

Re:Let's put it like this

[ZonkerWilliam]

Actually the Pulse Detonation engine, I've made a small one for testing, can use fuels such as kerosene and oxidizers like hydrogen peroxide (above 50%), most fuels deflagrate, in other words burn rather slowly, ICE (Internal combustion engines), as in cars, tend to deflagrate, they do not detonate. Detonations are hypersonic burning of fuel basically. A PDE needs to go from deflagrate to detonation typically. This is done using a long tube which retains the fuel long enough to go speed up the burn, the tube length also needs to resonate with the detonations or time to burn. PDE's are very efficient as the fuel burns mostly completely and is converted into thrust.

Re:Pulse detonation engines AKA piston engine

[BigBuckHunter]

Pulse detonation engines: This used to be called "piston engine"

Correct, except these don't have the pistons, rods, flywheel, or cam shaft(s).

It's more like a bunch of PVC potatoe guns duct-taped together, sans potatoes, hooked up to a distributer cap and battery.

There, I just dumbed it down enough for FOX news.

I thought the idea was to put them against the wall and then shoot them. But sealing them inside a wall and then flying a plane against it might work too. However I don't think they will be doing much apoligizing afterwarts.
In conclusion: I like your plan, but I suggest letting them apoligize first.

Surely the correct response would have been 'no, that was an artist's impression.'

The news anchor may be employed to use baby-talk, but there's no excuse for a supposedly informed correspondent to go along with the idiocy. The pride in ignorance is obviously annoying him, why doesn't he challenge it?

Equally when asked to explain in 'English, not science-talk,' perhaps he should have said 'Yes, perfectly possible. Let me explain' and delved into some of the simpler theory of reciprocating engines, turbojets, high and low bypass fans and scramjets. When challenged he could then say, "what with words less than 3rd grade level? Ah, no sorry, not possible.'

"How can a human cope with going that fast?"

What is this, 1850? The scientist didn't explain very well that you only feel any force under acceleration admittedly, maybe he thought that when the guy said 'going fast' he meant 'accelerating fast'. But OMFG, some people obviously just don't think... don't notice that travelling at 500mph on a plane feels no different to being at a 'standstill' (ignoring the earth/galaxy's rotation), it's only the acceleration that stresses the body. Later on he was saying "Surely they need some kind of special equipment?" :/ sure, they need a hypersonic plane..

sekrit planes!

[jollyreaper]

I really do wonder what they're dicking around with out there. The two bits of evidence I heard of supporting the idea of a fancy post-SR-71 wonderplane were the donuts-on-a-rope contrails (which the link says can be produced by conventional aircraft under the right conditions) and linear earthquakes picked up on seismographs that do not follow any existing fault line that seemingly originate in the atmosphere. I've seen that "fact" mentioned before but have no idea how accurate it is.

http://tinwiki.org/wiki/Aurora#Contrail

I have no proof one way or the other, I just think it would be surprising for the government to retire something as valuable as the Blackbird without having an even better replacement in the works. Then again, using logic to explain government decisions is often a losing proposition.

Re:sekrit planes!

[R2.0]

"I have no proof one way or the other, I just think it would be surprising for the government to retire something as valuable as the Blackbird without having an even better replacement in the works. Then again, using logic to explain government decisions is often a losing proposition."

The unofficial/official line was that the government DID have something better - satellites with resolution much better than previously available.

That being said, I'm with you and think Aurora is real - hell, the SR-71 "didn't exist" for a long time.

I'm glad to finally find out what that is

[n9hmg]

At least this propulsion system has been flying since at least 2005 (I don't remember the season). It sort of sounds like a piston engine, but leaves a contrail of "puffs" and appears to be very fast.
I heard what I thought was a strange-sounding small plane. Found the contrail, and the head growing far ahead of where the sound was coming from, and I couldn't see the contrail source. Maybe 20 seconds from hearing the sound from the north to seeing the head of the contrail disappear to the south. It was flying down the Front Range of the Rockies. I was just north of Gunbarrel, Colorado.

I googled around and found conspiracy nut sites talking about "Aurora", which fit my observations well. Since then, I've just been waiting for it to finally be revealed. I guess the research has gone on far enough to start production.

Now I don't know much about weapons and planes, but I do know that excepting a few dowdy old school journalism institutions, whenever the media reports on something I do know about, the inaccuracies make my skin crawl. Given that is probably true for the knowledgeable in any field, it follows that most news stories make their readers or viewers more ignorant than they were before.

Uncanny valley

[hey!]

It isn't just that they act dumb. It might be just me, but those Fox newsreaders give me the creeps. It's their eyes. Their body language and facial expression are so animated, but their eyes are so lifeless.

I may be politically biased against the network, but there is something in the flawless but soulless choreography of Fox news that stinks of evil. The effect reminds me of C.S. Lewis' novel That Hideous Strength, in which a government think tank called NICE manipulates its members using their ambitions and insecurities. As their ambition drives them toward the coveted membership in the inner circle, their fear drives them further into themselves. By the time they make it into the inner circle, there's nothing outwardly left of their humanity to enjoy it. They can pass superficial inspection, but the closer you look, the more obviously robotic they are.

What makes That Hideous Strength such an effective story of the supernatural is that the mechanisms of damnation are so psychologically plausible. Anybody with sufficient money could actually put the NICE methods for turning people into passive tools to the test.

I don't know about the people on the screen, but Fox definitely plays this game with its viewers. It appeals to greed and fear.

Re:Slick reporting

[DrLang21]

Religion is easy. It is obsurd to think that the car came into existance through millions of random design mutations that somehow did not cause it to blow up. The only reasonable explanation for the existance of the car is that it was designed and created by some intelligent being. Therefore God exists. QED.

This news item is misleading and wrong in several ways: Blackswift is a DARPA proposal so it is a paper design and no prototype has been built, it does not use PDE, but ramjets and scramjets, it has turbojets to get it to ramjet speed.

Only example I know of something flying with PDE is Long-EZ and the technology still has a ways to go.

Re:Slick reporting

[R2.0]

In fairness, humans DO have a problem with high speeds, but it's biological, not physical. A person's reaction time has a lower limit, and it is quite possible to exceed that limit and cause problems with a person's control of a vehicle regardless of gee forces. If this were not the case, then all it would take to be a race car driver would be an extra capacity bladder.

That being said, I'm pretty sure the anchor meant "wouldn't they be crushed?" Given that the main viewers of morning news programs are soccer moms killing time after their spawn have gone off to what passes for education in this country, I'm sure tat was their interpretation as well.

Re:Slick reporting

[R2.0]

"I don't think it's reaction times that matter so much as perhaps just brazen balls out fearlessness. Fast reaction times are useful when you overstep the limit or someone ahead blows a tyre out or something like that, but most of the time I don't think it's the defining factor in what makes a good race-driver. For most types of racing I'm of the opinion that anyone could do it with a bit of tuition and cash."

Perhaps - but "overstepping the limits" or "someone ahead blows a tire out" happens ALL THE TIME in racing; while anyone may be able to turn competitive times on a racecourse, that's different than an actual race. Joe Blow may last one or 2 races, but without getting his reaction times up to speed he will either lose miserably or crash - either way his racing career is likely to be quite short.

It's like saying because Ray Charles could be a perfectly good driver, because he drove a Mercedes out in the middle of the Mojave; sure, he operated the controls competently, but lets not call him a "driver".

Likewise, comparing lap times for professional racers in a "reasonably priced car" to the average guy is ridiculous; drop them both in an F1 car and see what happens - I mean, the only difference is that one is faster than the other, right?

Let's make it even simpler - American style drag racing. Simplest automotive sport in the world - go 1/4 mile as fast as possible. No turns; pure acceleration. Now, lets put Tony Schumacher in a Honda Accord next to me in my identical car and race. We will probably get to the finish line within .400 seconds of each other - .400 being the difference between when he reacts to the starting light and when I do. We will both finish in about 15 seconds with a top speed around 90 miles per hour. AWESOME - that means I'm competitive with a 5 time National Champion - racing just can't be that hard.

Now, put us in his car - a top fuel dragster. A competitive car will travel the 1/4 mile in under 5 seconds, and finish at well over 320 miles per hour. Are you really going to say that I will still be competitive in that car? Assuming I actually survive the trip?

That's the problem with egalitarianism - some people really ARE better than others.

Videos like http://www.youtube.com/watch?v=GeMhxvYq1Ww really don't help :p

http://www.youtube.com/watch?v=pGmesn5WXeE is another hilarious but sad one. My impression is that the general american public just isn't very well educated as to geography and cultures outside of the US. Most people in the world understand american culture (even if it is a skewed version) because of all the stuff that comes out of america - movies, music, fast food places, etc. So when people visit America they generally know what's going on, but I doubt it's the same when your standard American visits, say, China.

I admit that I'm not very well versed on American geography of course - I could name a lot of the states but I couldn't point out where they were on a blank map or what most of the capitals were, I tend to just think of the US as a big blob, just as I think of Russia and China mostly as big blobs and don't know much of the internal geography of each, but I know roughly where most countries in the world are on a map. I reckon that's how most people in the US think about the rest of the world though.. just a big blob of non-American-ness that they don't really need to know about (which is fair enough as long as they aren't wanting to go to war against countries they know nothing about).

Not meaning this to be a troll or anything, it's just how I see it. I've met some dumb Americans, and I've also met some highly intelligent ones (mostly over here to study). I also dated a Canadian, I'm not sure what that says about me. I used to regard Canadians as generally smarter than Americans, but now I just think of them as weird selfish bitches *cough*

Mach 10/Hypersonic Skyhook = Cheap Access to Space

[StCredZero]

If we have the technology to build a plane that can fly at Mach 10, then we can build Zubrin's Hyersonic Skyhook without nanotube cables or any kind of unobtanium. This would give us Space Elevator priced access to space!

Basically, you build a beanstalk that doesn't go all the way to geosynch, and doesn't go all the way to the ground. It's a lot less massive and doesn't require the same stupendous tensile strength as a Space Elevator. A Mach 10 hypersonic plane could deliver cargoes to the bottom end, perhaps with the help of a small booster rocket on the cargo pod. After the cargo is attached, you winch it up and use ion engines or interaction with the earth's magnetic field to accelerate the skyhook. (Which would be cheaper, since ion engines have huge delta-V, and magnetic interaction requires power and no fuel.)

Too simplistic

[kbahey]

This view is overly simplistic.

The Ashari school of thought came in early, and gained a lot of support perhaps from the 10th century onwards.

At the time, the other schools of thoughts, which are not "sects", within the majority Sunni Islam were as follows:

a) the Mu'tazili, which were supposed to a rationalist theological branch. They had followers among the elite, but very little among the majority. They managed to be the "state religion" under Al-Ma'moun. This caused severe oppression of the traditionalists, going to extremes, such as crucifying leaders of opposing sects, making them more popular among the public at large, and refusing to pay ransom for Muslim prisoners of war of Byzantium who were tested for their creed and did not confirm to Mu'tazilism. They are touted today by some factions in the West as an alternative to the literalist Hanbalis, forgetting that they were so oppressive when in power. Their school of thought lived on among a few scholars and elite, but faded from existence. Some of their thought got absorbed into other schools, for example the Shi'a Twelvers of today.

b) the Hanbalis (traditionalists), which have a literalist legalistic interpretation of theology based mainly on scripture and tradition. Their thought lives on within the contemorary Salafi/Wahhabi, which is not necessarily militant, although Al-Qaeda subscribes to that thought.

c) the Asharis, which sought to merge aspects of the above two in theology, retaining both tradition and reason. This was the majority thought from the 10th century on. One famous Ash'ari scholar was Al Ghazali of Persia in the late 1000s. He sought to refute many of the theology of the philosophers, and was also a Sufi. He is incorrectly blamed for the decline in scientific thought.

d) the Sufis (mystics), with a whole spectrum ranging from just "I am not interested in materialism" to "I get my revelation directly from God". They were mainly interested in ethics, conduct and sometimes esoteric practices (like the Whirling Dervishs), and there were Sufi strains within sects, e.g. Shi'a. It is important to note that Sufis were very prevalent in the 18th to early 20th century. Many anti-colonial leaders of "Jihad" were Sufis, such as Omar Al Mukhtar in Libya, Abdul Qadi in Algeria, the Mad Mullah in Somalia, Al Mahdi in Sudan, and Shamil in the Caucasus. Again, some in the West advocate Sufism as a replacement for the literalist Hanbali, forgetting that Sufis were the main religious opposing force, to the extent that Russia outlawed all the Sufi orders!

e) the philosophers, who were really a few, but had a lot of influence. They went beyond Mu'tazilis and wrote commentaries on Aristotle and Plato's work. The adherents to those were mainly medical doctors who were polymaths, such as Ibn Sina (Avicenna), Al Farabi, Ibn Rushd (Averroes), and others. They were often close to rulers, but did not seek to make their thought a mass thing like the Mu'tazilis did.

f) the Zahiri (literalist jurists), which never gained popularity, apart from the famed debates of Ibn Hazm of Cordova. Although literal in Sharia, they were not so in matters of theology, more of a mix between Mu'tazilis and Ash'aris.

The golden age of science under Muslim rule between 900s and 1200s, and carried over to the 1400s in some areaas. Ash'aris were well established during that time, with most rulers and the public being Ash'aris.

Read the articles of Dr. George Saliba of Columbia University sometime. They detail how scientific thought continued well into the 15th century.
