The Moiré Effect Lights That Guide Ships Home

Sagemind says...

Hi Tom, I'm a merchant navy officer who used to work around there, although I never came across this particular light... Sector Lights and Leading lights (parallax) are the internationally recognised marine signals for this sort of use (white light centre, with red and green lights either side to guide you to a safe channel, which i'm sure you've researched and are aware of), but one thing that doesn't come up too often is lines to specifically avoid, and as such there isn't an internationally recognised means of transmitting this with lights. The signal is pointing towards the danger, which is unusual in maritime practice, but it's certainly not a common light and isn't in the IALA buoyage system used for identifying marine hazards.

If it's in a marina, which i think you mentioned, it'll be specifically to stop boats dropping anchor on the submerged cable within the marina's jurisdiction, and it'll be specifically referenced in the marina's or the solent by-laws as an anomalous regulation. (I don't have time to go and hunt it down, but it'll be there as a local reg.) As far as i'm aware, that's the only possible reason for it. It's an unusual solution to an unusual problem. I could of course be wrong...i bring no hard evidence to the table!
Hope it helps

Largest Turboprop in the world Antonov AN 22 Manchester

moonsammy says...

A few years ago I had lunch at a restaurant with my extended family for some event (can't recall specifically), and as we were standing around talking in the parking lot afterwards, the AN-225 flew over us. We were pretty close to the airport and it was either landing or taking off, so it was quite low to the ground and surprised the hell out of us. We didn't have the slightest idea what it was, but the configurations of the landing gears and six jets made it clear it was damned unusual. Found out later that the beast was one-of-a-kind and a bunch of people were at the airport watching for it, which made it clear how lucky we were to randomly catch that.

I had no idea there was a propeller-based counterpart. 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.

First Interstellar Asteroid Wows Scientists

bremnet says...

Uh, what? Nobody said that at all. It is neither a "classic example" nor an assumption. The trajectory has been tracked since it was discovered, which is hyperbolic around the sun, and the speed of the object is such that there is no way it could have accelerated to its current velocity due to the gravity of our sun alone, hence it has to be interstellar, picking up kinetic energy from another system outside of our own. The orbit is not improbable, it is unusual compared to trajectories of asteroids that exist within our own solar system. Sharpen your crayon there bud, and stop trying to impress people with your new thesaurus for hipsters (come on, "undergird"?? Really?)

shinyblurry said:

They said they believe it is interstellar because of its improbable orbit. This is a classic example of the assumptions that undergird much of modern cosmology

The Amazon’s Boiling River Kills Anything That Enters

oritteropo says...

You might be disappointed, I'm pretty sure that this is the video where he gives the explanation, which is fault line geothermal heating. In the TED talk he says that it's a really unusual type of geothermal heating that's not found anywhere else. Most hot springs are volcanic, but not here.

Here is an article which shows the various fault lines in and around Peru, including one close to Pucallpa - http://temblor.net/earthquake-insights/ecuador-peru-and-colombia-faults-hint-where-large-earthquakes-could-strike-2128/

I'm really disappointed that this short video didn't explain why the water is so hot. Not even a hint at an explanation.

Guess I'll have to watch the TED Talk now.

Stranger Aliens

ChaosEngine says...

Devil's advocate:

First up, If we're looking for "something we can't imagine", by definition we are unable to search for it.

Second, there's every possibility that aliens ARE very similar to us. There's a principle known as the Mediocrity Principle that states that if you pick a thing at random from a set, it's more likely to common than unusual. In this case, we are picking from the (hypothetical) set of life-sustaining planets, and using the only example we're aware of: Earth.

It's not unreasonable to assume that Earth is typical of life-sustaining planets. There doesn't appear to be anything particularly special about it.... it's a rocky planet in the "Goldilocks zone" where water is liquid. We've found plenty of those.

So there's actually a good possibility that life on other planets could face the same evolutionary pressures and arrive at the same solutions.

Aliens might not be that different at all.

Irish People Taste Test American Rum

oritteropo says...



I don't think it's that unusual to describe drinks by their origin. Cuban rum for instance is very much a thing, as is American Whiskey vs Scotch Whisky vs Irish Whiskey (or the highly regarded Japanese).

I wouldn't know one way or the other for the Thanksgiving vid. Scalloped potatoes are a thing here though I had some last night.

eric3579 said:

It's entertaining and fun to see the reactions. My issue is they say "American" rum as if it's somethings different than other rum. They just can't say Irish people drink rum, because nothing about that is interesting. I recall the Thanksgiving video when the food they chose was so not typical American thanksgiving food. To the point id never heard of some of it. I just think they are willing (imo) to fudge a bit just to make a video. Anyway im just bitchin and moaning for no particularly good reason

Climate Change: What Do Scientists Say?

newtboy says...

What do real scientists say?
...the one's he worked with all said Lindzen is totally wrong, and his views are not held by the vast, VAST majority of other scientists that actually work in climatology. He's a political shill now, working for 'conservative think tanks' to deny climate change.

https://insideclimatenews.org/news/06032017/climate-change-denial-scientists-richard-lindzen-mit-donald-trump

Note, his graph at the beginning that appears to show no significant rise because as usual they start in late 97-98, a super hot El Nino year (the hottest on record) typically used as a starting point to pretend that temperatures aren't rising as fast as they are. Start at any other time to see how different the results are. This graph contains the hottest 15 years in recorded history over a period of the last 19 years. That's pretty telling by itself.

1)the climate is always changing-but according to natural cycles, we should be in a cooling period, not a warming period.
2)so at least in his mind, everyone agrees CO2 is a greenhouse gas that causes warming...that's better than most deniers.
3)"little ice age"-During the period 1645–1715, in the middle of the Little Ice Age, there was a period of low solar activity known as the Maunder Minimum. The Spörer Minimum has also been identified with a significant cooling period between 1460 and 1550 (it was not caused by low CO2 levels), and CO2 is produced more in warmer temperatures than cold, so starting shortly after then you can claim the CO2 levels have been rising since well before the industrial revolution...which cherry picked like that may be technically true but is again misleading by starting at an unusually low level following a low level solar period, but the level of that rise has consistently risen since the industrial revolution, and is incredibly higher than any natural mass releases besides rare massive super volcano eruptions that caused mass extinction events.
4) just plain not true, and not agreed on by scientists.
5)What they actually said-
Improve methods to quantify uncertainties of climate projections and scenarios, including development and exploration of long-term ensemble simulations using complex models. The climate system is a coupled non-linear chaotic system, and therefore the long-term prediction of future climate states is not possible. Rather the focus must be upon the prediction of the probability distribution of the system�s future possible states by the generation of ensembles of model solutions. Addressing adequately the statistical nature of climate is computationally intensive and requires the application of new methods of model diagnosis, but such statistical information is essential.

Confident prediction of future weather is not possible, weather predictions are based on statistical probabilities too. Because they aren't perfect doesn't mean they're wrong, useless, or should be ignored until they're 100% right every time. More funding for more study will improve the predictions consistently, but we are intentionally defunding them instead.

Religion channel? As in the religion of climate change denial? That's not what that channel is.
Philosophy channel? What?
Learn channel, only if the viewer looks into his BS elsewhere to learn the truth.
Lies, yep...controversy, yep....politics, yep....conspiracy,OK. His ilk are steeped in those, but you left out money, the driving force for all the deniers controversial, political lies and crazy conspiracy theories. ;-)

Its a fuckin emu!

Why It's Almost Impossible to Run a Two-Hour Marathon

oritteropo says...

You mean apart from the explanation that the speed required to run a marathon is close to a flat-out sprint for most people, and that the maximum speed that you can sustain over two hours depends on the three factors that they explained in the video? It was discussed around 2:10 in the vid.

The handful of people have physiology that gives them unusually high oxygen uptake, lactate thresholds, and running efficiency.

It's slightly clickbaity because Nike... and despite serious cheating their attempt on the sub-2 hour marathon to sell shoes failed by 26 seconds.

p.s. The Grauniad had an article on what the rest of us can learn from these elite runners https://www.theguardian.com/lifeandstyle/2017/may/06/secrets-two-hour-marathon-men-alter-running

dannym3141 said:

At no point in the video was there an explanation that came close to answering why it is almost impossible to run a two hour marathon. Or why only a handful of people could ever come close to it.

In fact, a lot of parts seem like they were created in a rush. At one point he says that mid 60s is "nowhere near" 70 or 80. When the average is 40? Is the scale logarithmic? If so it wasn't mentioned.

I'm very grateful for the information i did learn in the video, it was a nice little bit of info about running and runners. But it fell far short of investigating the 2 hour mile or answering the questions it posed. I wish videosift will not become a home for clickbait.

Thor: Ragnarok Teaser Trailer

moonsammy says...

That does look quite excellent. I may be unusual in having quite enjoyed the first two Thor movies, and have also like what Waitit's done to date. Don't think I'll watch any more clips of this so as to not spoil anything else...

Trigger Happy Cop Attacks Private Investigator

cosmovitelli says...

Thing is people are simple, and they go by what seems normal based on their norms. A serious dude who acts unusual and confident is terrifying for a noob cop who knows he can get shot by a serious gangster facing a multi life term in a nighmare profit prison if he blinks. The whole situation in the US seems to now be terrified men pointing guns at each other with shaking hands. When I visit I'm just glad to get out alive.
