SpaceX, and the people in this thread, are comparing the vehicle cost to fuel cost, which is kinda cheating. It's not the cost of the fuel that matters, it's the cost of building the vehicle larger to hold that fuel -- and the fuel needed to launch that fuel -- that matters. So let's do the math!

Most data taken from http://spaceflight101.com/spac...
Basic info:
Stage 1: 23 tonnes structure, 400 tonnes fuel
Stage 2: 4 tonnes structure, 93 tonnes fuel
Payload: 13 tonnes

When launching, the first stage burns all 9 engines at full thrust for two and a half minutes. The re-entry burn and landing happen on a single engine, and from eyeballing the videos (including this one that shows the re-entry burn) appear to take about 30 seconds total. Assuming all burns are near full thrust (which is the best way to do it), that means the landing burn takes about (1/9) * (0:30 / 2:30) = 2% of the first stage fuel. Let's double that to 4% to provide a generous safety margin: that works out to about 400 * 0.04 = 16 tons more fuel.

This fuel is carried up to the moment that the second stage separates, so it subtracts from the mass of the second stage. Second stage plus payload weighs 110 tonnes: without the landing fuel, you could have scaled that up to 126 tonnes, a 15% increase.

So, landing the first stage reduces the payload SpaceX can launch, and thus the money they earn, by about 15%. In exchange, they recover about 75% of the cost of the launch hardware. So it's worth doing, even after you subtract off the cost of recovery and refurbishing. Maybe not the game-changer Elon Musk wants it to be, but it's a win.

Wait....isn't it climate change now?

It's been climate change for a while now. https://www.youtube.com/watch?...

4 It is a cover story for military aviation R&D.

Bingo. USAF even admitted as much, back before they took this off their website.

People really do see lights in the sky that seem to move in ways our aircraft can't. They're just projections. And please ignore the Chinese demonstrations of such tech. It's clearly not a militarized version of this.

Whatever you do, don't look up "blue beam", it's clearly 100% infeasible. There's no plan to stage an alien invasion.... even though a presidential candidate in TFA is currently setting up the pitch. Plans may have changed, but the PSYOPS tech remains the same.

Imagine getting blown back into the stone age... In a few short generations all the tech we have will be gone it will become like today's rumored legends of wizardry. Then those powerful few who secreted away tech and retained control of the skies can safely re-emerge, even more powerful than before. Any sufficiently advanced technology is indistinguishable from magic. So, to become Gods, elites just need to reduce the relative tech level of the populace...

Oh, come on, that's just a silly theory. There's no global effort to manufacture consent for population reduction on the grounds of climate / pollution fear-mongering. It's not like there's an Agenda 21 nor Agenda 2030 to dictate global policy that aligns with such (you haven't read them, have you? Of course not, you're a member of the slave class). Keep in mind that whites are less than 10% of the population of earth, and their birth rates are in decline. That means it's brown people who are the "population problem"... Nah, couldn't be. It goes against all liberal sensibilities to think that way. Of course bigger government can only lead to "social" benefits, never harm. Corruption is a fairy tale. Panama has no papers, and Emperors wear no clothes (in the Bohemian Grove).

Beware of all claims of the existence of extraterrestrials. It could just be our secret space program. I wonder what they're hiding behind that projection covering the moon?

The world needs to wake up and stand united against the U.S and their proxy wars and illegal invasions.

Or, just acknowledge the game at hand and play along. If the places US wants to invade simply pretend to be decimated and invaded, etc. via propaganda, then we can avoid all this bloodshed and still manipulate the people of earth into a New World Order (link includes top politicians using this term). Either way the outcome will be the same. Oh, and in case you haven't been paying attention. USA = Muscle. UK = Finance. Vatican = Ideology. Libya, then Syria, next is Iran on the chopping block whether anyone wants it or not. Fact is, it's not beholden to the internationalist bankers, and its ideology is counter to the Vatican's, so the US will muscle them up after tricking them into getting a nuke (or planting evidence thereof).

Get on board with the NWO or get turned into rubble. The choice is yours. I don't like it either, but them's the breaks. What are you going to do about it? Start WWIII? That's exactly the end game these elites want...

Shut it down!

You're out of touch with reality. Currently the #2 best selling laptop on Amazon is a Chromebook. In fact, Chromebooks have been best sellers on Amazon for a long time now.

When is the last time you saw a TV commercial for Linux or Chromebox or anything besides Windows? (for desktops, we're not talking about phones here).

Actually, I was thinking of the New Riders...

I'm sure Nye (Cocteau) is right, the Millennials have been taught/conditioned to believe anything a person in position of authority says. It's really quite sad. Skeptics are needed and necessary. https://www.youtube.com/watch?...

Of course the western news reports I saw talking about the Panama papers with slick background images showing Putin and Assad, despite them not being named in the documents. Yeah, that's not conspiring anti-Russian / anti-Syrian propaganda at all. Nope. Nothing to see here.

WE SLEEP. THEY LIVE. Sweet dreams.

I'm telling you that it will be four way encryption and what you want still won't work. As in, I use 2 Live Crew approved encryption on top of the Comey Approved encryption.

That or I just make sure any device I own isn't running Comey Approved encryption in the first place if at all possible. And if not, make sure anything I want kept private is only running 2 Live Crew Approved crypto.

Really?? We are supposed to respect the opinions of a bunch of whimpering babies that can't stand the sight of a Trump sticker on their campus without running in fear?? People who have signed petitions to ban the first amendment??

I suppose if Mr. Nye is desperate enough to look anywhere for support, he'll turn to anyone. Even the chronically clueless...

He acts like the government is doing some kind of favour to the citizens by providing protection and that somehow the citizens are obligated to give up their liberties as payment.

It's the government's FUCKING JOB to protect its citizens. They don't get to have any kind of special credit for it and they certainly don't get to have any kind of special payment (ie. private data) for it.

This reminds me of a bit that Chris Rock did a long time ago about niggers trying to take credit for shit that they are supposed to do.

Chris Rock: "You're SUPPOSED to you dumb motherfucker!"

Automated refueling tech

Just the other day I had a conversation with an 11th grade student and a science teacher about global warming. Turns out, the students were doing a research essay on the subject, one page, and the teacher accepts every paper that's backed up with good sources. And they have a good conversation even evaluating some of the sources. He openly tells students that he firmly believes global warming is real, but it's an open dialog with students.

Not every school discourages open conversation regarding climate change. And I'm equally frustrated that there's just as much closed-minded fervor from both sides of the conversation.

In my study of the topic, I've concluded that climate change is happening, and humans are partially responsible for the change. But the Earth has ways of compensating for the change, though some of these compensations will necessitate either adaptations or extensions from all walks of human life. We humans have had such success in adapting to our environment that we should have no troubles adjusting, but ironically, we resist change. In order to adapt, we need to talk about the changes taking place and how to respond to them accordingly. That's becoming incredibly difficult; climate-change believers are so self-righteous, they feel humans need to take full responsibility for its existence and pretentiously claim we have to "undo" it all; and climate-change deniers don't want to accept any responsibility at all, especially due to the costs.

Climate is changing every moment of every day, and the complete calculus that is climate is so complex, it's nothing short of arrogance to think we alone are at fault. Milankovich cycles. Volcanic vents. Solar output. Water vapor. Not to mention butterflies, methane emissions from cattle (and don't forget buffalo), forest fires, surface volcanic eruptions, and who knows what else. The only explanation I have for taking a ~30 year warming trend within the billions of years of our planet's existence and constituting it as a global crisis is because we humans like to imagine that we're in control of this world. But we're not.

It angers me even further that, just because there's so much in this world that we do not and cannot control, there's no good reason -not- to do what we can to clean up our planet. Until we can find another one to take its place, and find a way to get a subset of the human population there, this is the only one we have. So let's not fuck it up.

dozens of movies have done this.

How about Terminator 3 - self driving vehicles, controlled by a maniacal bitchbot...

Modern environmentalism is a religion. It has deities, a set dogma, a clergy, heresy and excommunication, and even its own apocalypse (complete with punishment for sins).

But so was a G4 Macintosh.

The first uploaded organism is already done. It's a worm. It actually a composite of several worms - C. elegans has the useful feature of every individual being absolutely identical in cell layout.

Here's the worm having been Matrixed into a simulated body and environment: https://www.youtube.com/watch?...

Interestingly, it swims just fine without neurons. Basic motion seems to be a function of muscle cells alone - the nervous system just determines where to go.

It's more than one high resolution snapshot. It's many cameras and capable of monitoring large areas simultaneously.. It's called the ARGUS-IS and it was featured on Nova and it's been around for several years. Here's a link to the video

Maybe this is what they have been spending years trying to invent the invisible and undetectable dark matter for?

No, silly. Dark Matter is just cold elemental hydrogen, which vibrates at the same temperature as the alleged "cosmic background radiation" that was left over by the "big bang". Dark Energy is just the EM field, which astronomers completely ignore, even though a bar magnet will prove to you that electro magnatism is stronger than gravity.

Every comet we've been to has been a hard dry rock covered with fine dust, not a dirty snowball. Cometary tails are not water vapor, they are formed by the same process as the Aurora Borealis -- it's an electrical discharge event. The sun emits lone protons (H+ ions). This creates an electrical charge gradient in our solar system. Objects, like hard dry comets, which come sailing in from far out have a more neutral charge, but as they approach the sun the difference in relative charge allows electrical discharge to occur, and charged particles begin to glow. If you bombard silica (rock) with H+ ions some of the Oxygen from the SiO2 will break free. Some of those O's bind with H's and become HO (hydroxide), far less some become H2O. This is why we can see some H2O in the spectrogram of a comet's coma and tail, but can not find any vents nor water at the surface of them. The electrical discharge is why comets glow in UV light.

Once you realize that electricity plays a much greater role in the solar system, you'll soon infer that it may play a larger role in the universe. In fact, you'll find that when you account for EM field, you don't need nearly so much dark matter or dark energy to explain how galaxies hold themselves together, in fact some say you'll need none at all. With EM in the picture, filamentary galactic arms of spiral galaxies become simple to explain, just as are the filamentary structures of cometary tails, and of magnetic loops seen erupting from the Sun.

In fact, once you account for the EM field things like "pulsars" with irregular pulses make more sense: Perhaps you're seeing a simple cosmic scale capacitor / resistor discharge event, not a neutron star. And as for those black holes? Well, when you factor in the EM field they don't really need to be so large either. Indeed a galaxy's electromagnetic nexus can explain most of the behavior we're seeing with stars that have tight and fast orbits.

Next time you see an astronomer, ask them: If a small refrigerator magnet can overcome the gravity of our planet, then what of the immense magnetic fields generated by our sun? Ask them why they ignore EM field's contribution to the cosmic model. EM is stronger than gravity, then why do they think gravity is the dominant force? The answer will surprise you, I'm sure. The fact is: They foolishly consider the universe to be electrically neutral meanwhile claiming that a non neutral cosmic background EM field is permeating the universe... The cognitive dissonance is quite scary when you start to look into the issue deeper. It's like they don't want anyone to even consider things mentioned in this post.

If the representative were Named, Shamed and Blamed they might just loose their cushy jobs.

While somewhat off-topic.. Ennnhh.. after the most recent John Oliver episode, I don't think those representatives have quite the cushy job you think they do. They're basically glorified telemarketers, and I don't envy a single one of them.

There's a better way to do it, and it could potentially image the whole brain, all at once. It can image whole brains of mice and other smaller mammals at the neuronal level, and we can tag each type of brain cell automatically.

Once you've got the raw data a simple AI program could map the structure logically by recognizing the tracers and plotting the connections...

Of course, this cheap and simple method may not put money in the right pockets. See what I'm thinking?

Bernie Sanders warned us about this back in 2011 or so...

https://www.youtube.com/watch?...

Sanders made a speech on the Senate floor in October of 2011 that warned that a proposed trade agreement with Panama would open the floodgates of American money flowing into off-shore tax havens, a plea that ultimately fell on deaf ears as the agreement was signed by President Barack Obama later that year.

So they were running essentially an automatic version of this guy

Because art is all about the artist attempting to elicit an emotional response from the person experiencing their work, and since no so-called 'AI' has actual emotions, it can't understand art, and therefore can't 'create' art.

Even if I accept your narrow definition of art as "elicits and emotional response", I can't accept your non sequitur: having emotions is not a precondition for eliciting an emotional response. Just consider a flat tire to know that.

CARRIER LOST, or more commonly, NO CARRIER, is a meme originating from the message an over-the-phone modem would send when the connection was dropped.

Now you know.

if you insist a machine cannot create art, then in this case the hand holding the paintbrush is the person(s) who pulled the 'go' switch, and/or the software author(s)

also, humans with complete apathy and/or completely flat affect (the two things laymen could consider "no emotions", normally due to brain damage) can understand and create art

something less clear: does that dog that likes colour combinations and does actually, weirdly, compose paintings[1] - does it count as art? what if it were a chimp?

1. The civil war and the resulting fallout set up the current system where federal law dictates and states obey.
2. Sanctuary cities and pot-is-legal states are breaking federal law.
3. Obama and the current congress are too pussy to send in federal troops to enforce the current federal law. (also, they're OK with it. It's just that they don't dare say so were voters can hear the message loud and clear).
4. That last part, about enforcing the current law, is why Trump is making a big splash and he's right about one thing: either we have laws and we obey them or we don't. Vid kind of related in a funny way

Oh no! It seems that the science isn't quite settled here! It seems that socialization DOES have an effect!
No, it's settled. Boys are more interested in things, girls in people, and this is not due to socialization
https://www.youtube.com/watch?...

Social Justice people like to think that it is extremely hard, if not impossible, to determine to what degree nature and nurture influence behavior, and advocate that we must take the position that we can manipulate everything by socialization, since we can't know for sure wether it's determined by nature, nurture, or a combination of both. It's essentially shifting the burden of evicence.

In fact, it's pretty easy to determine what is innate, and what is learned. All you have to do is look at the variation across cultures. The behavior that varies is socialized, while the behavior that remains constant across cultures is innate. Boys prefer things, and girls prefer people, across all cultures. There are several other such differences we can observe.

Stepping back a bit, based on what we know about sexually reproducing species, we should certainly expect there to be many innate differences. Men and women, like all living things, are optimized for reproductive success. That is, behavior that increases fitness ( read: produces successful offspring ) is selected for.

Thing is, men and women reproduce VASTLY differently. Since womens reproductive potential is capped by biology, she can only grow so many offspring in her lifetime, while mens potential is capped only by access to mating opportunities, it follows that men and women will act differently. Men will display behavior designed to maximize their access to mating opportunities, while women will act in ways that maximize her ability to raise her offspring. Let's remember that a really smart ape is still an ape.

If men acted like women, being more choosy about who they copulate with, that would be detrimental to their reproductive success. Likewise if women acted like men, and tried to have sex with as many men as possible, that would be detrimental to her reproductive success because such behavior will produce less fit offspring. You can point to bonobos, and a couple of other exceptions in nature, but these species evolved in very specific and unusual environments. Bonobos have no natural predators, and have easy access to food, which is a rare luxury in nature. Their sexual behavior is just as much biologically hardwired as chimpanzees'.

These predictions fit perfectly with observations we can make. Men and women do in fact behave this way, in all cultures. There is no culture where these roles are reversed, so claiming that this behavior is "socially constructed" makes no sense.

Everybody sing along ...
