Lifeboat Front Flip

charliem says...

How is that a fail? It did exactly as designed....entered the water and made itself upright.
These boats have 5 point harnesses on the seats for exactly this reason, you strap in real tight and go for a joy ride

Confident motorcyclist escapes in front of police motorcycle

sillma says...

The kid was driving a moped, which is legally allowed to go around 28mph. I suspect he's stopping the kid to check if the moped's been tuned(which it obviously has).

Transcript:
(I'll skip the repeated greetings)
Cop:
"From the police, good day. Follow that moped."
Kid:
"ok." proceeds to try to run away like the tard he is.

after the chase:
Cop:
"Get on the ground!"
Kid:
"fuuuu"
Cop:
"God damn this stuff, these *unclear* can't god damn keep upright. They don't know how to drive, fuck. Are you all...are you really that fucking poor at driving? Turn that camera off --"

Competition is for Losers: Natural Monopolies Aren't Forced

newtboy says...

Just wow. No competition is how you get advancement, but competition stifles it by making you too busy?!? Maybe in utopia where business act like the most upright and benevolent of people and always act properly and altruistically with their customers coming first, but that's not how it works on the planet I live on.

Evolution's shortcoming is Intelligent Design's Downfall

criticalthud says...

we're pretty dumb when it comes to our own neurology.

a more obvious and better example is perhaps our continuing struggles to stand upright in gravity, with our inherent asymmetry.

She Failed Science

SpaceDude says...

I don't think she stepped forward, she would have been leaning back a bit to keep balanced while holding the ball. As soon as she released the ball she had to stand upright to remain balanced. Hence when it came back it smacked her in the face. The prof should have thought of that. If he had held the ball instead it would have been better.

Also did you notice the smirk on his face when she got hit? He doesn't seem to care at all.

Last Week Tonight with John Oliver: Climate Change Debate

coolhund says...

Very funny. Its always "scientists" who bring that up and who first brought that up. Do you even read those reports? Scientists and their studies (more like very flawed simulations) are always quoted. First they said (Mojib Latif and others) that there wont be any hard winters anymore due to AGW. After it became evident that those utterings were utter bullshit, they said that hard winters will be very often due to AGW (PIK and others) and after we got a normal winter again, they said that this is typical for AGW too (PIK and others again).
If it wasnt for them, this hype wouldnt be nearly where it is.

They just say what is convenient and what fits into their agenda. Its all about money and personal security. Nothing more nothing less, they just think its something different due to their indoctrination. AGW has become a huge self-sustaining (thanks to those corrupt "scientists") economic booster where insurances, scientists, politicians and many many companies (even oil companies - yes, check the global warming lobby) and their lobbies are benefiting from. Its simply not possible to talk about it objectively anymore. And if you try, people like you will come up and defend it like a religion, and prove this fact very quickly. Just look at "bio" fuels. Its a HUGE part of economy already, but it simply isnt eco-friendly at all. Instead people are starving because mono cultures are used instead of different plants for food, so much water is used for producing bio fuels that people have to suffer. The rain forest and others are cleared to be able to put more mono cultures up. Companies like Monsanto are becoming more and more powerful because of it and studies that bio fuels are bad for lots of engines are being censored or simply not funded since even car manufacturers profit from it when engines blow up sooner.

More extreme weather? Bullshit aswell. Thats simply not true, as quite a few (ignored by the "consensus") studies have shown. Its just the reports about even the tiniest things that have bloated up in the globalized and interconnected world of today and untold truths that are fooling you and of course the agendas that need to be kept upright with even the tiniest happenings that fit into it. Next time when you see a report, ask yourself if something like that would have been mentioned globally 20 or 30 years ago.

Take the flood in Pakistan for example. Oh, it was soooo bad and soooo AGW caused, oh the horror, we will all see the same thing and worse in our own countries if we continue to sin in the face of our go-- err scientists!
No, it wasnt. It was as normal as all the very common floods there before. It just wasnt mentioned that since the 70s Pakistans population has tripled and the vast majority of those people have settled down on the fertile lands around the (straightened!!!) rivers.

If that wasnt enough, people like you even completely ignore the fact, even if all their claims were true, that warm periods were ALWAYS much much better for this planet and its inhabitants than cold ones and colder ones than we have right now (we live in an ice age after all) were always bad, if not catastrophic.

And because of that fact I wont be that stupid and waste my time here with more replies, since you guys have made it very obvious already where you are coming from.

Just one little thing to think about for you guys (yeah I still have hope, though its prolly not very realistic), since the rest of my posts will get marginalized by your ignorance anyway:
Just because most scientists are pro-AGW doesnt prove crap. It was always only very few if not only a single scientist who tried to prove many other scientists wrong in their assumptions and most scientists were wrong and very arrogant, especially if they formed something like a society. But like before, there are thankfully still a few of them left who treat science as science and not as their religion or extension of their ego.

ChaosEngine said:

I missed this earlier, but I think you'll find that there are almost no climate scientists who will say that for any given weather event "it's climate changes fault".

The media like to bring this up whenever there's a big storm or heatwave, because they know that extreme weather event + AGW "controversy" = ratings. And they go talk to someone (possibly wearing a bow tie) and ask "is climate change causing this?"

At which point, most scientists will respond that while no single incident can be taken as definitive proof, increasing frequency of extreme weather events does fit within the predicted model, and if AGW continues we can expect it to be hotter in summer and also see more storms etc.

Wait, that was a SAFETY video?

Picking up a Hammer on the Moon

Chairman_woo says...

That's almost exactly what I just said 17-18kg in earth terms. Do you think laid on your back you could easily throw a 17kg object 1.5-2m upwards?

He's not doing a push up he's trying to jump upright. Launching nearly 20kg of weight far enough to get to your feet would take some doing that way I'd say. Just lifting 20kg with the arms alone is an effort never mind throwing it which is effectively what's happening here.

This is part of the reason I defaulted to thinking in terms of rocketry as it's not as simple as just someone trying to lift something, they are trying to propel themselves 1-2m upwards with only a thrust from the arms. Much better to wiggle around/push up to get to your knees so one could bring one's legs muscles to bear (made very difficult by hard to bend suit).

Frankly I think it would be a total pain in the arse getting back upright. If it weren't for the suit you could easily push up to your knees and then straighten your legs but the inflation is going to make that very hard work (but doable after a struggle to one knee as other video footage proves).

The alternative however which sparked this whole argument i.e. lay on your front and push off with your arms. That I think would be considerably harder than you are making out. Throwing a 17kg weight with only your arms over 1m in height is not what I'd call effortless.

My old CRT monitor probably weighs about 20kg, it'd take everything I had to throw that over 1m up into the air. Without the power of your thigh muscles and the rigidity of your spine 20kg is quite a lot really.

How high can you "jump" with only your arms? (like those super push-ups where you clap your hands in between to show off) maybe a foot or two if your really really strong? So with the extra weight of a suit and reduced gravity multiplying the result by 6 under lunar gravity, 6feet is probably just about attainable for someone in peak physical shape. But it's defiantly not what I'd call easy!


Re: conspiracies The only one I really take at all seriously any more is the idea that 2001 (esp the book) was perhaps (very) loosely based on actual events. I have time for it simply because of Arthur C. Clarke himself who was going to give an interview (which he rarely does) on Project Camelot of all things but died about 2 weeks before it happened. If you know anything about project camelot you'll know whatever he had to say was going to be mental but then again he was very old and eccentric and plenty other people involved in the space program have "jumped the shark" so to speak. (Edgar Mitchell talks about aliens on a regualr basis, Buzz Aldrin has spoken about monoliths on Phobos, pilots being followed by "Foofighters" in WW2 etc. etc.)

But it's basically wishful thinking on my part, the story and implications are remarkably plausible for what they are but that is all they are. Combined with the whole Jack Parsons/Alastair Crowley connection to the JPL my creative juices start flowing. However the obvious counter argument i.e. that the world is largely run by genuine lunatics is never far from my mind either (look at the whole "men who stare at goats" thing).

I'll listen to anyone and some I'm even prepared to believe on their own terms but I have to defer to actual evidence where it exists (or does not exist). Consequently while I'll listen to someone like John Leer talking about stuff that would seem outlandish even in a science fiction story, people why claim the moon landing was a hoax tend to get the cold shoulder as it's pretty demonstrably not true/hard to believe.

I realise that's kind of backwards but willing suspension of disbelief is a lot easier when there's really no tangible evidence either way. (why I suspect huge incomprehensible delusions like those espoused by many religions get so much traction. It's easier to believe the big lie than the small one)

Jolly entertaining though regardless

MichaelL said:

No need to go through the whole Newtons things... easier to keep it all in kg since that's how we think anyway. So on the moon, astronaut + suit = 100/6 = 17 kg. Only about 40 lbs... So an astronaut should have no problem doing a pushup there.

As I said, probably more to due with the awkward, pressurized suits.

However, the jumping part... well, that's a puzzle to me why they aren't able to jump higher since I don't see any mechanical disadvantage. It's one of the arguments for the 'fake moon landing' thing.

However, if the moon surface were 'spongy' then it would be like trying to jump out of a barrel of mud.

Re: conspiracy thing... Alternative 3 claims that Apollo astronauts went to the moon, but discovered the bases that had already been there and were threatened/sworn to silence. Curiously, Neil Armstrong became a public recluse after his career as an astronaut, rarely giving interviews or talking about his experience.

However, if you believe the 'we never went to the moon at all' version, the claim is that NASA hired Stanley Kubrick to film the fake moon landing thing based on his realistic looking 2001.

Picking up a Hammer on the Moon

MichaelL says...

In this case, it is. Lift a 1 kg(mass) on earth 2 metres and drop it. If will hit the earth with a force of 9.8 Newtons. (F=m x a) That's its weight though we tend to use the kg instead of Newtons to express weight. To lift that mass, you would have to exert 9.8 newtons of force.

On the moon where acceleration due to gravity is 1/6 that of earth, that 1 kg mass would only weigh about 1.8 (9.8/6) Newtons. So it would take correspondingly less force to lift it.

So our astronaut should be able to easily push himself upright in theory.

The real reason he can't do it probably has more to do with the design of the suit (top heavy, not very flexible) and the loosely packed surface composition of the moon. Like trying to right yourself while wearing an inflatable sumo outfit in a McDonald's ballpit.

The high jump answer... when a high jumper clears 7 feet he is really just lifting his centre of gravity about 3-4 feet. He just twists his body horizontal to get his legs and feet over.

On the moon then, he would only lift his CofG about 18-24 feet (plus say 3 feet for his legs). So his record jump would be less impressive than you might intuitively think.

In other terms weight alone isn't the whole story (as I assume you well know).

Picking up a Hammer on the Moon

Chairman_woo says...

Actually I'm about as English as they come but crucially I spent my advanced academic career studying Philosophy and rhetoric (lamentably only to Hons. due to laziness) and consequently have an ingrained habit of arguing around a problem rather than relying on established parameters (not always entirely helpful when discussing more day to day matters as I'm sure you've by now gathered but it is essential to working with advanced epistemological problems and so serves me well none the less). I'm also prone to poor punctuation and odd patterns of grammar when I'm not going back over everything I write with a fine tooth comb which has likely not helped. (A consequence of learning to describe tangent after tangent when trying to thoroughly encapsulate some conceptual problems with language alone)

That said, while I may have gone around the houses so to speak I think my conclusion is entirely compatible with what I now understand your own to be.

I didn't want to describe my original counter-point by simply working with the idea that weight is lower on the moon relative to the earth (though I did not try to refute this either) because that would not illustrate why a 2-300kg man in a space suit still takes some shifting (relatively speaking) even if there were no gravity at all. (Would have been faster to just crunch some numbers but that's not what I specialise in)

Sure you could move anything with any force in 0G (which I do understand is technically relative as every object in the universe with mass exerts gravitational forces proportionately (and inversely proportional to the distance between)) but the resulting velocity is directly proportional to mass vs force applied. Weight here then, can be seen as another competing force in the equation rather than the whole thing which it can be convenient to treat it as for a simple calculation (which is what I think you are doing).

To put that another way I was applying a different/deeper linguistic/descriptive paradigm to the same objective facts because that's what we philosophers do. Single paradigm approaches to any subject have a dangerous habit of making one believe one possess such a thing as truly objective facts rather than interpretations only (which are all that truly exist).


In other terms weight alone isn't the whole story (as I assume you well know). Overcoming inertia due to mass scales up all by itself, then gravity comes along and complicates matters. This is why rocket scientists measure potential thrust in DeltaV rather than Watts, Joules etc. right? The mass of the object dictates how much velocity a given input/output of energy would equal.

Gravity and thus the force in newtons it induces (weight) in these terms is an additional force which depending upon the direction in which it is acting multiplies the required DeltaV to achieve the same effect. Moreover when concerning a force of inconstant nature (such as pushing up/jumping or a brief burn of an engine) brings duration into play also. (the foundations of why rocket science gets its fearsome reputation for complexity in its calculations)


Man on the moon lies on the ground and pushes off to try and stand back up.
This push must impart enough DeltaV to his body to produce a sufficient velocity and duration to travel the 2 meters or so needed to get upright so he can then balance the downward gravitational force with his legs&back and successfully convert the chemical/kinetic energy from his arms into potential energy as weight (the energy he uses to stand up is the same energy that would drag him down again right?).

One could practically speaking reduce this to a simple calculation of weight and thrust if all one wanted was a number. Weight would be the only number we need here as it incorporates the mass in it's own calculation (weight = mass x gravity)

But where's the fun in that? My way let's one go round all the houses see how the other bits of the paradigm that support this basic isolated equation function and inter-relate.

Plus (and probably more accurately) I've been playing loads of Kerbal Space Programme lately and have ended up conditioning myself to think in terms of rocketry and thus massively overcomplicated everything here for basically my own amusement/fascination.


Basically few things are more verbose and self indulgent than a bored Philosopher, sorry .


Re: Your challenge. (And I'm just guessing here) something to do with your leg muscles not being able to deliver the energy fast/efficiently enough? (as your feet would leave the ground faster/at a lower level of force?). This is the only thing I can think of as it's easier to push away from things underwater and it certainly looks difficult to push away hard from things when people are floating in 0g.

So lower resistance from gravity = less force to push against the floor with?

Warm? Even in the Ballpark? (Regardless I'm really pleased to discover you weren't the nut I originally thought you to be! (though I imagine you now have some idea what a nut I am))


If I got any of that wrong I'd be happy for you to explain to me why and where (assuming you can keep up with my slightly mad approach to syntax in the 1st place). I'm an armchair physicist (not that I haven't studied it in my time but I'm far from PHD) I'm always happy to learn and improve.

MichaelL said:

I have a degree in physics. I'm guessing that English is maybe a 2nd language for you? Your explanation of mass and weight is a little confusing. With regards to our astronaut on the moon, it's the difference in weight that matters. He should be able to (approximately) lift six times the weight he could on earth.
(Sidebar: It's often been said that Olympics on the moon would be fantastic because a man who could high-jump 7 feet high on earth would be able to high-jump 42 feet high (7x6) on the moon. In fact, he would only be able to jump about half that. Do you know why? I'll leave that with you as a challenge.)

Picking up a Hammer on the Moon

Chairman_woo says...

That's not what I was saying at all though perhaps I explained poorly.

So imagine you are in a 0 gravity environment. You have 2 balls (lol) one has a mass of 1 kg the other a mass of 100kg. You throw both equally hard. What happens?

One ball travels away from you at 100x less the velocity of the other. This is intertia, it is an effect of mass not gravity. Gravity is an additional force but it's absence would not change the fact that a big heavy space suit requires a significant force to move at a usefully velocity in the 1st place.

It was perhaps misleading to use the example of a fulcrum (lever) but in this context it's quite illustrative. If it was 0 gravity you could apply a tiny force to a massive object and just wait however long it takes to get it where you want (like an infinitely long lever). When gravity becomes a factor duration becomes more and more of a concern (like the fulcrum of the lever gets shorter and shorter).

Concequence: the lower the gravity the easier (less work/deltaV) it is to move an object. However a massive object still requires a proportional large force to move in a useful way (in this case fast enough to overcome 0.16g for long enough to get upright).

I'm not saying gravity has no effect (quite the opposite) I'm saying big heavy thing requires big heavy force to shift even in reduced gravity environments.


As for bases on the moon, mars, stargates, ueo's, void whales, phobos being hollow (phobos is some crazy shit), hexagon on Saturn etc. Etc. I'm not outright dismissive, but to treat it as anything but food for thought/entertainment is a little worrying to say the least. What do you have to go on there other than the testimony of other people who claim to have been involved or whatever?

There's no hard data avaliable to the likes of you and I on such things. Many of these ideas cannot be entirely refuted, but nor can they be confirmed either. That puts us squarely in the realm of superstition and religion.

I'm a part time discordian/khaos magus/git wizard so I do have more time than most for superstition and flights of fantasy but I steer well clear of treating any of that kind of think as objective fact.

The realms of materialism and idealism should stay entirely separate except when they converge and compliment each other e.g. If I can imagine a black swan and then go out and find one (after performing the necessary experiments to disprove any other possible explanations for why it might seem black) then I can tell others that black swans are definitely a real thing. The same cannot be said for say the flying spaghetti monster or the chocolate tea pot orbiting the sun even though believing in such things makes my life more interesting under certain circumstances (and such liberated thought processes can eventually lead to as yet undiscovered ideas which may indeed prove to be "true" or helpful).

"Given all theories of the universe are absurd, it is better to speak in the language of one which Is patently absurd so as to mortify the metaphysical man." -Alaistair Crowley

Praise be to pope Bob!

MichaelL said:

So you're saying on Jupiter or any other super-giant planet, we should have no problem walking about, lifting the usual things such as hammers, etc with no problem because the mass is the same as Earth?
Hmm, didn't think gravity worked like that. I always read in text books that on the moon, you should be able to jump higher because gravity was less than earth... but you say no.
Damn scientists always trying to confuse us...
(Pssst... weight and mass are different things. Weight measures gravitational force... the force that you have to overcome to lift something... less gravity = less force to overcome)

As for the conspiracy thing... you do know we already have bases on the dark side of the moon and Mars right? Look up Alternative 3...

Picking up a Hammer on the Moon

MichaelL says...

Yeah, why wouldn't he just get into the pushup position, grab it then push hard to upright himself. Gravity on the moon is only 1/6 that of earth.

I'll tell you why... cause it's FAKE! He's in a movie studio in a heavy suit so hasn't the strength to be able to push himself upright.

Polish Excavator Fail of Epic Proportions

Intelligent cow knows how to use a hand pump to draw water

poolcleaner says...

Red queen effect: Parasitic humans feed off of the cow, steals the natural flowing water and installs human-centric water holes. In competition with the human parasite the cow is forced to learn to use the water pump. And thus the arms race between cow and human.

Who will win?

My money is that humans destroy themselves and cow survives, finally free of it's parasitic relationship with the upright mammals. They then go on to evolve into upright cow people. Only to encounter the humans again.

They then join with the radioactive green humans (nuclear fallout survivors) and zombie humans (the ones that didn't survive the fallout but were taken over by parasites of their own) to kill the humans, many of whom are dwarves and really small midgets.

Some hippies that bonded with trees are found to have survived, each with their own vision of what it is to be a tree hugger. Some of them join the humans (with their now dominant midget genes) and some of them join the green humans and cow people.

Along the way we discover that in China pandas have evolved into panda people and all along there were werewolves and shit. Including dimensions made entirely of fire with slimes that thrive off of radiation, only to become what is perceived as fire elementals and H.P. Lovecraft's things were real too. Oh and the entire pantheon of all people from all of time.

Society rebuilds itself but war never changes.
