Grreta Thunberg's Speech to World Leaders at UN

bcglorf says...

@newtboy,

"Stupid to use all these differing sets, that only adds confusion to an already technical and confusing topic."

I'm just glad they stick to metric, with sea level rise you don't even get that .

"No matter what, it's incontrovertible that every iteration of the IPCC reports has drastically raised their damage estimates (temp, sea level) and sped up the timetable from the previous report."

At least temperature wise the AR1 report had higher temperatures, and definitely higher worst case projection scenarios for temp than the latest. I can't say I checked their sea level projections, though typically they're other projections have followed on using their temps as the baseline for the other stuff and thus they track together. That is to say, if you can point me a source that reliably claims otherwise I might go check, but currently what I have checked tells me otherwise.

"I'll take the less conservative NOAA estimates and go farther to assume they over estimate humanity and underestimate feedback loops and unknowns and believe we are bound to make it worse than they imagine."

Which is fine, I only object if that gets characterized as the factually scientific 'right' approach.

"The NOAA .83C number was compared to average annual global temperatures 1901-2000...and oddly enough is lower than 2017's measurements."

Which is yet another source and calibration period from what I found. The 1901-2000 very, very roughly speaking can be thought of as centered on 1950, so in that fuzzy feeling sense not surprising it's 0C is colder than the IPCC centered on the nineties.

The source on current instrumental I went against is below:
https://climate.nasa.gov/vital-signs/global-temperature/

As for 2018 being cooler than 2017, that's pretty normal. 1996/1997 were the hottest years on record for a pretty long time before things swung back up. It's entirely possible we stay below the recent high years for another bunch of years before continuing to creep up. Same as a particularly cold day isn't 'evidence', the decadal and even century averages are where the signal comes out of the noise.

A Scary Time

ChaosEngine says...

"You give the woman a victim hood mentality ."

First, sexual assault happens to both men and women.
Second, yes, because I am specifically talking about VICTIMS of sexual assault.

"What about the guy? He too carries this to his grave. He too sufferer a life of pain of a un erasable false accusation. "

Yes, a false accusation of rape is awful. I've said so multiple times now. But it's still not as bad as being raped. I don't want to break my arm, but I'll take it over being shot in the chest. See how too things can be bad, but one is worse than the other?

Plus, at least, with a false accusation of rape, there's a chance you will get your name cleared.

"The difference The man carries a tag on his back for all to see and discriminate against.
The woman carries internal pain. Which is hurt most?"

Easy. The rape victim.

"this does not give society the obligation to take her at her word just because she is a woman."

Which is exactly why I never said that. What I said is that anyone who makes a claim of sexual assault is "entitled to be taken seriously", i.e. have said claim investigated. Due process still applies.

"Even is false hoods are 1% - that is too much, if it is you. Just think today if a work colleague told your boss that you grabbed he upper spots? Not even rape. You would loose your job. Then what How do you explain this at the next job? No one would hire you , just to be on the safe side. You are black listed."

Can you please try using a spell checker? That is really hard to read. What the hell is "you grabbed he upper spots" supposed to mean?

Anyway, assuming you're talking about sexual harassment in the workplace, I would expect not to be fired until an investigation had proved I was in the wrong.

Again, false accusations are bad, and yeah, it would totally suck if it happened to you.

But it's just not that common. The numbers don't support your case at all. Rape far out numbers false accusations, and that's not even getting into other forms of sexual assault, like groping or catcalling, most of which isn't even reported.

Newsflash: most women don't WANT to be perceived as a victim of sexual assault.

"Trump has nothing to do with this."
Yeah, he does. He (and you) contributes to the culture that is more worried about a tiny percentage of false accusations than the NINETY FUCKING THOUSAND RAPES THAT OCCUR EVERY YEAR IN THE US.

Largest Turboprop in the world Antonov AN 22 Manchester

radx says...

Counter-rotating propellers sparked my curiosity when I first saw them on a British Seafire Mk46 at a flight show in the early nineties.

So my amateur's answer would be that it's about the problem of turning the engine's power into thrust. With increasing power, you can either increase the propeller's RPM or its area. So you either a) spin it faster, b) increase its diameter, c) use a more favourable blade geometry, d) add more blades.

a) and b) both lead to blade tips moving faster, and once they approach the speed of sound, wave drag sets in and ruins your day. b) also runs into issues in terms of ground clearance. Thus the Kim Jong-un blades on planes like the An-70: short and fat.

c) is rather difficult to do in terms of manufacture -- that's why more pronounced blade shapes are a relatively recent development.

d) on a single propeller decreases the efficiency of each blade as it passes through the previous blade's vortex. That's why, for instance, German planes in WW2 almost exclusively relied on 3-bladed propellers with increasing blade size, whereas Supermarine went to four and even 5 blades rather quickly. You can work the issue to a certain degree by modifying the blade geometry, thus the 8 blade props on a modern A400M.

Adding more blades by adding another propeller gets around d), although the aft prop still loses efficiency compared to the front prop. On the other hand, counter-rotating props massively reduces problems with torque, which can be rather horrendous for single engine prop planes. The Bf 109, for instance, is (in)famous for being difficult during take-off as it pulls to the side quite violently.

I don't know enough about aerodynamics to understand how stacking the propellers like that makes any sense, so I'm just going to assume it's some sort of Soviet technomagic.

The cops could be doing ninety miles an hour down city streets while running over random pedestrians, shooting at little old ladies and doing coke off a hookers ass and the department would still feel that their officers did nothing wrong.

Roger Waters Performs On The Late Show with Stephen Colbert

eric3579 says...

If I had been God
I would have rearranged the veins in the face to make them more resistant to alcohol and less prone to ageing
If I had been God
I would have sired many sons and I would not have suffered the Romans to kill even one of them
If I had been God
With my staff and my rod
If I had been given the nod
I believe I could have done a better job

If I were a drone
Patrolling foreign skies
With my electronic eyes for guidance
And the element of surprise
I would be afraid to find someone home
Maybe a woman at a stove
Baking bread, making rice, or just boiling down some bones
If I were a drone

The temple's in ruins
The bankers get fat
The buffalo's gone
And the mountain top's flat
The trout in the streams are all hermaphrodites
You lean to the left but you vote to the right

And it feels like déjà vu
The sun goes down and I'm still missing you
Counting the cost of love that got lost
And under my Gulf Stream, in circular balls
There's ninety-nine cents worth of drunkards and fools

My Life with the Thrill Kill Kult - Sex On Wheels

WeedandWeirdness says...

YES!! I freaking love this song, and loved dancing to it at the little goth hole in the wall club Ground Zero in Boulder. Of course this video just screams the nineties, but I can't help but *promote the viewing of crazy shit from that decade!!

Dr. Steven Brule predicts new planet years before Caltech

AeroMechanical says...

Yeah, there was that whole "Planet X" thing in the early nineties, and the assumption was that it was a planet with a highly eccentric orbit. I think I did a report on it in the second grade.

I don't recall what the evidence for it was, though, and that would make a difference. I don't think they had anything like the data we have now on the orbits of trans-Neptunian objects so it must have been based on something else, and I suppose that would make this "Planet IX" a different theory from "Planet X."

dannym3141 said:

I'm sure i've been hearing for years that it was likely there was a large planet far out in the solar system. Maybe i'm getting mixed up between guesswork and/or findings that were later disproved, but the media seem to find this a lot more of a revelation than the astronomers i know.

Pixels review - he really didn't like this movie..

Djevel says...

Kinda feel the same way ninety seconds into this review as the gentleman stated he felt after ninety minutes into the film in question. I would wager to guess that this is his shtick and his other reviews tend to run in a similar, vitriolic vein.

ZX14 Kawasaki motorbike bursts into flames at 400km/h

AeroMechanical says...

247mph isn't too ridiculous (though still insane). Pretty much all sports bikes are electronically limited to 299km/h (186mph), which is sort of an unofficial industry agreed standard arrived at in the earlyto mid nineties when the marketing was dominated by top speeds and it was getting out of hand. It's not something that someone determined couldn't bypass relatively easily though (and probably doesn't apply at all to track bikes).

Bosch self-drive car demo

MilkmanDan says...

Ten percent Devil's advocate here and ninety percent real: I'd be interested in the opposite of this. Driving in town (especially here in Thailand where drivers are completely insane, but really anywhere) annoys me / raises my blood pressure. But highway roadtrips are actually rather fun, nice scenery and fun roads. So a whole lot of the time, if I had to choose one or the other, I'd take the highway bits and let the auto-drive handle traffic and stop lights.

The progress shown here is impressive, but overall I think that things will only get really useful when the car can handle as much (or as little) of the drive as you want it to, all the way on up to driving 100% of the way from driveway to parking at the destination.

Wrestling - it's about the story

gorillaman says...

Is it too much to ask that they now recap all of professional wrestling from the early nineties to the present day in the same style, but greater detail? Match by match, ideally.

ABC News Bobbles Dismiss Obama's Funeral Selfie

chingalera says...

Well, the spin for me is making light of his actions at a state funeral using a non-journalistic idiot nobody as a skyped commentator-Major news corps are owned by those who placed him in power-I have no respect for this president whatsoever anyway, and watching him behave like a middle-school girl is to me, about as ridiculous as letting a schizophrenic African within 5 feet of him on worldwide television.


I agree that it's a complete nothing news item, ninety percent of so-called news is non-news anyhow-It's programming gullible minds to believe everything they hear.

A tank shell with your name on it

morelenmir says...

APFSDS - Armour Piercing, Fin Stabilized, Discarding Sabot. The American Abrams tankers used to call them 'Silver Bullets' back in the early nineties; maybe they still do. They were made largely out of natural or depleted uranium and they combusted slightly when shot through the air, leaving a faint glowing silvery trail behind. You could see it best at night obviously.
