Escape velocity is to leave the Earth-moon system. What they're trying to do is get into orbit. Guess if RTFA you would know who they were.
The goal is to build a slingatron big enough to fire a projectile at 7 km/s (15,600 mph, 25,000 km/h), which is enough to put it into orbit.
My response was to the individual who was talking about traveling 7,000 miles/second into LEO. Actually, I did RTFA, but I found their concept lacking and lost interest. There are much better ways (e.g., magnetic catapults) to launch objects that are much more practical. That said, I'm sure you're right about the velocities mentioned in TFA. Thanks.
I'd much rather read an article containing "because acceleration is inversely proportional to mass" than one containing "because F=ma"
Why do you imagine those have to be mutually exclusive? Explaining that "acceleration is inversely proportional to mass" and then using F=ma with a concrete example would demonstrate the concept much more clearly, no?
Without math, it's impossible to convey what you're trying to convey. The press is way too dumbed down already, and many times I've read science stories that are just plain misleading as they try to simplify the message.
Putting equations into news stories means that some people won't understand them, but most importantly it will encourage some of those people to investigate further, and learn how to read equations. If there's no math in the popular press in the first place, then there's no incentive for people to improve themselves.
Exactly. So what if everyone doesn't get the equations? As long as there is some explanatory context around them, that should be plenty. And some folks might even decide (as mentioned above) to investigate and learn something new.
Mathematics is the only way to accurately describe the universe and everything in it. As such, *everyone* should have a keen interest. Heinlein was a bit tongue-in-cheek, but I think he had it mostly right: Anyone who cannot cope with mathematics is not fully human. At best, he is a tolerable subhuman who has learned to wear his shoes, bathe, and not make messes in the house.” --Robert A. Heinlein
... this is about silencing dissent, nothing else...
You can guarantee that all the rape 'threats' were made up by JEW rabble rousers, so that we can 'think of the children' and report anything that anybody says, if the JEWS don't like it...
You know, little problems like the homicidal gas chambers being a myth... little lies like that...
The issue isn't that some folks said some unflattering things. The issue is that some folks threatened violence (rape and murder are violence) and some even tried (but apparently failed) to post the home address of this person. That's not just disagreeing or being a jerk on the Interwebs. Death/rape threats and attempts to track down the threatened is not just harmless fun for the trolls. I'm all for free speech (although this is in the UK, where they don't have guarantees of free speech) even when that speech is nasty or mean. However, threatening life and limb is something else altogether, IMHO.
When the projectile is moving at about 7,000 miles per second.. is it not going to heat up and vaporise when it encounters friction from the atmosphere and the slingatron? How hot will it get, and if the contour changes are irregular, will the projectile not deviate off its expected path? I think it makes more sense to build a super gun on Mount Everest, or use a stratospheric aircraft to provide a lifting platform to get a rocket out of dense atmosphere.
[Emphasis Added]
.037c? That seems rather excessive when trying to get to LEO. Then again, it will get you to the moon in 34 seconds and to Mars in less than six hours -- assuming you don't want to stop and look around -- then you'll need to decelerate.
I assume you mean 7 miles per second (escape velocity on a body the size of the earth is ~25,000 miles/hour) or are in a *really* big hurry.
What I don't understand is why NASA wants to reinvent the wheel for missions further out into space. Why does the NASA mission have to start from the ground with a new launcher for astronauts?
Or tell them an asteroid is the natural platform for manufacture and launch of kinetic weapons. Scary like a nuke (though not remotely as powerful) without the unpleasant radiation afterwards.
We need to start facing reality and figuring out how to deal with it. The faith that every racial group is exactly the same except for appearance was necessary for getting rid of Jim Crow and its associated evils. But now it has come to be a problem because it keeps us from finding how to deal with reality in a fair way.
I do too. If the neighborhood is all-white, I don't want to live there. I am a Caucasian. I decided early on that I want a more diverse area for raising my kids. It has worked out very well. E pluribus unum.
I used to say that too, but then it took a few break ins before I realized you can't always tell the difference between "diversity" and "ghetto" until you live there. Multa adversus paucos.
I've lived in a majority hispanic neighborhood for the past 17 years and it's been quite nice. Lots of families and children and the neighborhood is quite diverse (I live a few blocks from a major university). I suspect that you are confusing poor neighborhoods with neighborhoods with people of color. They are not necessarily the same thing. I've been to places which are lily white and very poor, where the crime is just out of control. The issue is poverty and hopelessness, not the amount of melanin in the skin of the residents.
But, what happens when students go to college and take out loans to do so, then cannot find adequate work to pay back said loans? The rest of us taxpayers will be on the hook to bail them out. I wouldn't say that is good for the economy, either. Not to mention it is a waste of someone's talent/skills/training.
That's not true. While student loans are generally guaranteed by the government, they cannot be discharged in bankruptcy. This creates a semi-permanent debtor class who *need* high wages to pay back the loans that allowed them to get the degree that they hope will get them a good job. It's just one more nail in the coffin of our economy.
There have been several reports that the outage is causing hosted DNS to fail, leading to a number of unresolvable websites.
Confirmed here. DNS resolution was down for about an hour this morning for our domains registered with Network Solutions, no problems with domains registered elsewhere.
As I mentioned above, DNS resolution is *still* spotty for my domains.
DNS name resolution from Network Solutions' DNS servers seems to be functional for 50-60% of requests based on a small sample (resolution of hosts in domains I manage). The Website is back up.
I don't agree with raiding a company for providing subtitles; that said do you really think anything more than a tiny fraction of users are putting the subtitles against legally owned material?
I have no idea. I'm a stereotypical American. I don't think. I just consume way out of proportion to the rest of the world and complain when my super-size fries are missing a few greasy morsels. What is more, I'm barely literate so subtitles aren't really useful to me. I prefer the "news" crawl on the "truth" TV network, Fox News. I can't read it, but it comforts me to know that there's so much truth there that they have to augment my favorite talking heads with it..
I was asking a leading, hypothetical question. Whether it reflects reality is irrelevant. If you don't get the obvious point, you're probably a stereotypical American like me. As I understand it, most movies are released first in English (and possibly French and Spanish as well) first, with long delays before crappy subtitles and overdubs become available in other languages. This is done simply to create more profit for the distributors by releasing multiple versions and manipulating prices.
Nothing he said was trolling.
Nothing he said was BS.
Nothing he said was pro-RIAA/MPAA.
A producer, or creator or author or whatever you want to call him, has a fundamental right to profit off his created work (his "goods and services") the same as any other. Merely supporting that right is not the same as supporting the MPAA, nor is it BS.
And so if I legally purchase a movie and then use sub-titles created by someone else so I can understand the dialogue, I'm ripping off the creator of the work? Please explain how that is.
I doubt that's true. In Pennsylvania a horny prosecutor (his motivations were suspect, and he ran a bad girls boot camp) tried to go after a teen for sending a picture to a boy, the judge sided with the teens. Unless you find an example of the contrary I'm calling bullshit.
Besides, this is America. We're allowed to believe in any crazy thing we want.
The USA is so enormous, and so numerous are its schools, colleges and
religious seminaries, many devoted to special religious beliefs ranging
from the unorthodox to the dotty, that we can hardly wonder at its
yielding a more bounteous harvest of gobbledygook than the rest of the
world put together.

Yes, they both espouse extreme left-wing positions associated with the National Socialist Party (Nazi).
Nazi's were totalitarians and, thus, left-wing.
As were Attila the Hun and Genghis Khan.
The particulars may vary at points but the man thrust is the same.
Right-wing positions are conservatives, some libertarians, anarchists.
ACs are getting dumber by the minute. Sigh. Fascism [e.g., the Nazis] is fundamentally right-wing.

the m they have is meters not miles, so 7km/s.
I'm not sure who the "they" in your post are, but Earth's escape velocity is 11.2km/sec or 6.96Miles/sec. Oh, and I rounded up to 7 miles per second.
I don't know exactly what you're talking about, but thanks for sharing!

Because.

And since they've already set up the secret prison on the moon, we need only wait until the prisoners start 'throwing rocks at us'.

There is only one race. The human race. Homo Sapiens. There most certainly are genetic and cultural differences between individuals and groups within our species. However, classifying intelligence and the potential for success on the amount of melanin in the skin of an individual is foolhardy and is not borne out by the research.
I judge a neighborhood by the number of black and hispanic people in it. Just like the other small-minded, hateful scumbags like me.
There. FTFY.
I do too. If the neighborhood is all-white, I don't want to live there. I am a Caucasian. I decided early on that I want a more diverse area for raising my kids. It has worked out very well. E pluribus unum.

Heinlein, in his adult (not teen) later books assumed widespread acceptance of homosexuality and plural marriage.
At least Lazarus Long's giant freakin' harems of women following him seemed like a plural marriage.
For explicit discussions of plural marriage from Heinlein, see his Hugo winning The Moon Is A Harsh Mistress.

Yep, the state sure profits, why the state makes money running orphanages, paying for the foster system, and operating prisons.
Nobody else is getting rich off that system.
Just the state.
Not sure how you figure it's the *state* making money on this. Actually, it's the Prison/Industrial complex making all the money. Even with the kids.
