How one NASA image tells dozens of stories

spawnflagger says...

interesting video, but many of his same examples were in this 2012 NASA video: https://youtu.be/Q3YYwIsMHzw

Also, not to detract it's usefulness (and cool factor), but many people seeing this photo think that's how the Earth actually looks at night - it isn't. That composite uses satellite data from Suomi NPP's VIIRS sensor, which can detect much dimmer light than the human eye, and part of the compositing process was to normalize brightness of individual pixels (so dim lights get brighter, and bright lights don't washout adjacent pixels). More details here:
https://www.nasa.gov/mission_pages/NPP/news/earth-at-night.html

Even some cool night-time videos from ISS (example: https://youtu.be/FG0fTKAqZ5g ) are made using still photos with long exposure time (1+ seconds) See FAQ.

This did lead me to a live webcam from ISS that I didn't know existed: https://eol.jsc.nasa.gov/ESRS/HDEV/

PFAS: Last Week Tonight with John Oliver (HBO)

newtboy says...

Nonsense. Pre industrial agriculture wasn’t very damaging in most cases…and when it was it was on a minuscule scale compared to industrial agriculture.
Pre industrial building wasn’t excessively environmentally damaging in most cases, certainly not to the point where it endangered the planet or it’s atmosphere.

It's utterly ridiculous hyperbole to say we have to be cavemen to not destroy our environment. We don't even have to revert to pre industrial methods, we just have to be responsible with our actions and lower the population massively. With minor exceptions, pre industrial farming caused little to no permanent damage, and it was almost all easily repairable damage. (With a few exceptions like Rapa Nui that may not have been over farming but cultural damage, we aren't exactly certain what happened there).

I eat berries now, don't you? I grow raspberries, blackberries, black raspberries, blueberries, strawberries, and Tay berries myself. People would be healthier if they ate berries, and they're tasty too. What?!

Yes, around 7 billion need to die (without procreating first). Better than all 9 billion.

There’s a huge difference between being occasionally deadly and so insanely toxic we destroy our own planet in under 200 years to the point where our own existence is seriously threatened.
Edit: toxicity levels matter as much as exposure levels. Cavemen impacted their environment at levels well below sustainability (mostly….the idea they killed the mammoths or mastodons off by hunting is, I believe, a myth….natural environmental changes seem much more likely to be the major influence in their extinction.). Per capita, modern humans have a much larger, more detrimental footprint than premodern humans, exponentially larger….and there’s like a hundred thousand times as many of us (or more) too. We need to reverse both those trends drastically if we are to survive long term.

Yes, progress includes risk, but risk can be managed, minimized, and not taken when it’s a risk of total destruction. We totally ignore risk if there’s profit involved.

This is a night time comedy show, not a science class. I think you expect WAY too much. It points out that there is a problem, it doesn’t have the time, or the audience to delve into the intricate chemical processes involved in the manufacture, use, and disposal of them. It touched on them, and more importantly pointed out how they’ve been flushed into the environment Willy nilly by almost everyone who manufacturers with them.

By that logic, Newt, its back to caves and eating berries for everyone. And 7 billion people need to die to make planet Earth sustainable.

Everything civilization does is toxic in some way. Even living in caves was deadly, ask the Mammoths.

I like how youre taking everything responsibly but in this case you might be lumping too many things into one problem. If we strive for any progress at all we have to take risks.

Maybe the consensus will be that we cant handle the production problems and need to ban the poly stuff, but this video was not the compelling analysis that would even push me in that direction.

Trump Lashes Out Over Report He Insulted Fallen Soldiers

newtboy says...

Like the fake story about him knowing personally how deadly and transmissible Covid is in January but telling people it wasn't deadly or a danger that he's admitted now that the tapes are public but denied for 6 months?

Too bad for you you're just parroting another right wing media lie, Bobby. That's why you can't find it reported anywhere besides right wing opinion "news".

What he said is....
"Goldberg then conceded that questions about anonymous sources were “reasonable” to raise, adding that he thought it was fine to “ask why people who have had direct exposure to Donald Trump, who know what Donald Trump has said, who know what Donald Trump has done, but won’t simply come out and say it.”"

The reason is obvious, they don't want their families threatened and attacked by rabid right wing terrorists like others have been.

You have no problem repeating anonymous lies Trump tells you he heard someone is saying on the internet, you know, like vaccines are made from alien DNA, hydroxy is safe and works against Covid, and illness is caused by demon jizz, but when literally dozens of current and former high ranking officials and military all confirm the stories, the fact that they rightly fear retaliation from Trump and the Trumptards only shows they're paying attention. He and your ilk have threatened and attacked every whistleblower he could find....and their families. Remaining anonymous is smart and reasonable....and protected by law.

Not surprisingly, yesterday he was bragging about how he spends his day working so hard for you....9 hours watching Faux opinion tv a day which barely leaves enough time to tweet 200 times before night night time. When does he take the time to lead? Saving that for his next term I suppose.

To bad another fake story.

The editor of the Atlantic just stated well they might be wrong.

"Call to a member function query() on null" errors. (Wtf Talk Post)

ant says...

Yep, v2.48 and visiting video web pages. It seems to happen after submitting my videos when I access their web pages too. I haven't seen it happened again during the daytime today. I guess it only happened at night time? Check the logs?

dag said:

Quote hidden because you are ignoring dag. (show it anyway)

Hmm, weird. I haven't experienced it. Is it just on submitting or on other places too? Ant are you still on Seamonkey? Eric - I'm assuming Chrome?

Straight is the new gay - Steve Hughes

newtboy says...

I could use the same argument to try to outlaw cars.
When someone complains about smokers outdoors, I ask them if they drove there to complain, then offer a deal. They sit in their car with the exhaust plumbed into the window, I'll sit in a box smoking a fat cigar, last one breathing wins the debate.
Oddly, no one ever takes me up on that, but at least they all sheepishly drop their complaints.

As to banning it in private homes, this is a terribly slippery slope that gives power to others to decide what's dangerous to you....now consider getting too little sleep has proven to be harmful, so why not a legally enforced bed time based on the youngest or oldest person on your block? Your second hand noise might keep them up, harming them, so night night time is now 6pm. Consider all the food issues you mentioned as second hand groceries, because children have little option but to eat what parents supply, so no more sugar, salt, or processed foods in the stores because they might buy them.

The questions about health and safety vs freedom to be unhealthy are not simple ones to resolve, and it's impossible to fully safeguard both.

Daylight Saving Time 101

Nico Rosberg training at the PETRONAS towers, Malaysia

dannym3141 says...

I'm pretty sure you do need fitness to drive an F1 race, if not muscle strength to resist the forces you're undergoing then at least to reduce body weight. However this video is not in the remotest bit impressive as a feat of fitness for a number of reasons. He was walking in many of the shots, the video is edited a number of times so we don't know whether he was resting or not between, and his headband is gone in the final shot which means there was at least a small period of rest before the final moment at the top. It's also night time when he reaches the top but evening when he's at the bottom, so we can at least assume that it didn't take a small amount of time.

The fact that he doesn't look puffed at the top is wholly unremarkable.

Problems with French Numbers - Numberphile

Sagemind says...

Apparently you, sir, have never tried to explain to anyone who is French, that they are wrong. I believe that too is another word they choose to ignore in the French language. (the word, wrong)

My Mother in Law was French and being correct was the only option - ever. Which led to my wife explaining to me that "I" needed to be the one to let it go. Something that is very hard when you know the facts and they do not.

Things like "No it's okay to cross the white line and drive on the shoulder of the road, that's why they pave it. (the line is just a guide) It's up to pedestrians to to stay clear of the shoulder and never walk on it because that's just for cars!"
(That's a little one) Now, telling me it's daytime when it's clearly night time was an argument I'd rather not relive

PS: I know you were being sarcastic and facicious and all that. But I'm not -It's still a sore spot with me

gorillaman said:

Can't someone explain to France that they're doing it wrong?

French is just a terrible language in general; the sooner everyone's speaking English exclusively the better for humanity.

Tommy Edison - What Blind People Fear

Inglewood Police Chase (Wait for it..)

ivianson says...

Nope not a good place I live less than an hour away and right when you start to enter Inglewood you see nothing but houses and apartments with bars on the windows. Place looks decent during the day but night time is not a good time the hood rats come out of the wood work.

I noticed that too, hahaha. Probably not the best neighborhood in town.

VideoSift 5.0 Launch! (Sift Talk Post)

This Is Not Yellow (by Vsauce)

robbersdog49 says...

>> ^WaterDweller:

2:50 - Four hour exposure? Seriously? Surely, ten minutes in the darkest of nights would overexpose any image unless you used a really narrow aperture (and possibly even then)?


I wish. Night time photography would be a hell of a lot easier if this were true.

It's not. Four hours on a dark night seems reasonable to me. Depends on the camera settings used, of course, but if you keep the ISO low and use a reasonable aperture for good depth of field four hours sounds reasonable. The main problem with this is sensor bloom from the heat of the batteries and circuit boards in the camera itself.
