The Rotary Engine is Dead - Here's Why.

MilkmanDan says...

***update -- I was wrong about P-47 having a rotary engine, confused *radial* with rotary. Other than noting that mistake here, I'll leave my original comment unedited below (in which I draw erroneous conclusions based on that brain fart):

@eric3579 and @newtboy -

I was also quite interested in the "advantages" question. My grandfather was an armorer on P-47 "Thunderbolt" aircraft in WW2, and I knew that rotary engines were used in those.

Both of your answers tie in to the strengths of P-47s during the war. They were considered very reliable and resistant to damage (sorta like a WW2-era A-10; they could take a beating and make it back home). And of course, in internal combustion powered aircraft, power to weight ratio is even more important than in automobiles.

So, I'm sure that some of those strengths were at least partially due to the use of a radial engine. Not entirely, because other things in the design played a big role also -- like the fact that the P-47 engine was air cooled, so it didn't need a radiator system. As I understand it, comparatively light damage to a liquid-cooled aircraft like a P-51 that happened to damage the cooling system could disable or force them down for repairs... Not to knock the amazing piece of engineering that the Mustang was, but for sheer ability to take a beating and stay in the air, the Thunderbolt may have been the best US fighter in the war.

In the comments the project writes:

We are very passionate about our mission of rescuing as many images as possible before they're all gone. we have over 5,000 images in the archive currently and hundreds of rolls in the backlog waiting to be processed.


They also say that if you have any rescued films to donate, http://www.rescuedfilm.com/#!contribute-film/c1n4x

The photos on their web site are quite interesting too - http://www.rescuedfilm.com/#!rescuedarchive/c4si

trn-greg palast-summers secret banking crisis memos revealed

oritteropo says...

There was a tv series called the Ascent of Money with Niall Ferguson which featured the U.S. banking deregulation in one episode, and the tape of the senate hearing around the turn of the century was quite interesting. They realised that deregulating was trusting the bankers to do the right thing or the whole system could implode, and the bankers basically just laughed and said of course you can trust us...

A typical Bulgarian wedding dance

chingalera says...

Hey, that was one passionate couple of months of protest in 2013-Up until then Bulgaria was relatively quiet!
I did find this Bulgarian wedding ring quite interesting though...

rebuilder said:

@chingalera: Yes, fit, healthy people setting themselves on fire in the streets because their lives seem so hopeless!

OK, OK, that's an outlier, but Bulgaria isn't exactly paradise, either. They do seem to know a thing or two about weddings, though!

TEDTalks | Eleanor Longden: The voices in my head

Procrastinatron says...

Great comment! You raised many interesting points.

One important thing to note that the modern human mind is essentially like an advanced piece of software which runs on antiquated hardware (sort of like running Skyrim on an N64). As many as 7% (though I don't currently have a source for this at hand) of the general population are estimated to experience auditory hallucinations, and surprisingly enough, most of those people aren't psychotically structured. This is why auditory hallucinations are seen as a secondary, rather than primary, symptom of schizophrenia.

Rather, what is actually happening is that the antiquated hardware, for whatever reason, is showing its faults. The primitive responses which tend to stay dormant for most people are finding their way to the surface.

In other words, the truth of schizophrenia is that it isn't so much an illness as it is a regression to a more primitive version of the human mind. And as both you an Eleanor pointed out, this can have both pros and cons. Another example of a broken system which can produce contextually positive results is eidetic memory, which causes a person to be unable to forget.

And this is also something that I find to be quite interesting, because what it means is that mental illnesses are, in fact, contextual illnesses. A schizophrenic person is essentially "sick" because he/she has a bug in his/her software and as a result is unable to download patches from the rest of society. Go back 3000 years and it is entirely possible that auditory hallucination would have been the norm.

The reason for the stigma being so harmful is that it simply focuses on the wrong thing. It takes a secondary symptom, i.e. hearing voices, and makes it seem like the actual disease. In truth, the auditory hallucination is just an externalized version of a process which is actually internal. Where most of us simply have thoughts, the schizophrenic might instead hear a voice. To turn stigmatize those auditory hallucinations is to potentially cripple the sufferer's ability to perform basic maintenance on themselves.

This was amazing!

Many mental 'illnesses' can lead to sensory hallucinations, and it's likely that everyone knows someone with some such condition. There are neuroscientific reasons for these hallucinations, where sensory information is cross-linking with different portions of the brain. A person experiencing this is certainly abnormal, though the result can be harnessed as advantageous for a person to gain superhuman powers. A person who hallucinates halos of color around numbers gains an extra pneumonic for remembering them, a person who perceives a halo of color around people gains insight towards some of their own hidden feelings toward that person.

Many of us have problems dealing with traumatic events, or finding a healthy way to emotionally cope with problems. Some of us find healthy ways, and many of us don't, though it's an internal struggle for all of us. In her case, her condition let's her have an EXTERNAL struggle with her problems, which she uses as a tool to help her cope with otherwise unmanageable emotional issues.

Kudos to her for helping to remove some of the stigma for some of these mental disorders! I wish she could expand her horizon to people with other disorders, to help them achieve the same level of understanding and benefit.

Thanks for the warm welcome!

And y'know, so far the community here seems to be very warm, mature and honestly, quite interesting as well. With the sort of response I've gotten thus far, I would be surprised by myself if I didn't keep coming back for more, because intelligent and mature discussion is one of the things I live for.

So thanks again for the welcome, and for the offer of guidance! I may yet take you and pumpkinandstorm up on that offer.

Where Do Deleted Files Go?

dirkdeagler7 says...

I suppose you could consider it going on a tangent but I think it's more escalating the topic to the point of being interesting. Anyone who has been around computers for a long time knows how file deletion works and all of us have seen video or movies about people piecing together shredded documents.

The connection to life and information is quite relevant to the topic of deletion. In fact I believe even Stephen Hawking concerned himself with the concept of information loss (deletion) with regards to blackholes and the problems with conservation of energy (energy in the form of entropy). The resolution he came to involved the outer edge of a blackhole maintaining a version of this information forever.

If you expand the scope of the definition of information to be a specific state of the universe at a point in time, including its complex members (ie us and our consciousness), and remove the temporal importance of "now" then we are all information about states of the universe at varying points in its existence.

The point at which even that basic information (the current unique state of the universe) becomes erased or irrelevant (ie heat death when there is a perfectly homogenous distribution of energy throughout the universe) is quite interesting and depressing. At that point any record of the past and the ability to discern one moment of time from the next is gone. With no variation in the universe even time itself becomes impossible to measure unless your an objective viewer of the universe (God?).

The Most Profound 9 Year Old I've Ever Heard

brycewi19 says...

OK. Fair warning - the really good stuff really ends at the 3:08 mark.

But the baseball bat kid talk was actually quite interesting too, I found. His sensory perception between color and sounds tells me he thinks in non-traditional ways that are quite valuable.
