So the asteroids that landed in the ocean were likely cycled into the mantle, while asteroids that struck land left metals there. I'm not sure why having mostly oceans makes a difference here.
Honestly, I don't know if meteorites had a significant impact in the number of heavy metal deposits on the crust in the past 4 billion years. But I haven't seen anything to indicate that this couldn't be the case. Certainly most heavy metals prior to the crust forming sunk to the core. So meteorites are a plausible theory to me at this point.
Not really. Most modern cratons (where you're likely to find heavy metals) are at least 2.8 billion years old, which is easily old enough for an argument of where heavy metal deposits come from.
I'm not sure what you mean by "amount of land has been growing over time". The amount of area above sea level at any given time varies significantly in both directions due to several factors.
But you implied it. Rather, huge portions of continents are never recycled, and these are where you are likely to mine for less common heavy elements. This lends significant credibility to the previous authors argument that heavy elements came primarily from asteroids.
Perhaps you didn't stop to consider that a significant portion of asteroids are basically lumps of iron?
It's important to remember that these people were essentially some of the most physically fit people available at the time, and they're geniuses to boot. If someone is likely to live a long time, it would be them.
My parents had tubes put in also, and everyone loves them. As BLKBGK mentions, don't put them in bedrooms or anywhere else you want to be able to darken during the day for sleep.
That means things like cinder-block walls (painted with heavy duty marine paint), tough, thin, carpet and so on. No it is not the peak of aesthetics but it does the job well. It takes abuse and hardly shows it. The high schools in my home town were like that and they aged very well. Sure it did have a "prison" look to it I guess but it held up to the students.
It's possible to have both with minimal increases in cost. I recently saw a long-term building built with cinderblocks in the 1970s get renovated to make it more aesthetically appealing. The biggest thing they did was basically cover the cinderblocks with a plaster to give it the same smooth looks as drywall. You still can't put a fist through it, and if you chip it the plaster takes minutes to fill in, sand, and paint.
The building looks really nice now, is almost as durable, and didn't cost much to make that way.
Most people don't know that the LAUSD has been building schools at a completely insane pace. For the 15 years from 1997-2012, there has been an average of one new school opened every month! Sure, schools were neglected in the past, but there are tons of brand-new public schools in LA now.
Let me guess, you didn't read the article did you. Opening a new school every month isn't the problem. Wasting hundreds of millions of dollars, causing a budget shortfall, and having to lay off thousands of teachers while trying to open a new school every month is the problem. There are over 10 million people in L.A. County, so the school district and population are big enough to handle the number of schools.
Yes, the reasons behind the score differences need to be evaluate. What if one teacher turned a blind eye to cheating, while the other teacher strictly enforced the no cheating rules? On standardized testing, the cheaters win.
It's pretty easy to control for that and other variables by simply following the progress of students as they move from class to class through the years. This also controls for teachers that just teach basic skills for standardized tests, and those that teach more broadly.
If the average score of students that are taught by one teacher is 20% higher than other students in following years, then that teacher apparently taught the kids something important and/or inspired them. Alternatively, if the average score of students that are taught by one teacher is 20% lower than other students in following years, then we need to get rid of that teacher.
Of course, this only works in larger schools where there are always multiple teachers teaching the same class.
A straight Blu-Ray rip is often 25GB+ for 1.5 hours. Although, for sake of argument, a Blu-Ray has a maximum bitrate of 36Mbps, or 4.5MB/s. That limit is reached pretty easily when using DTS-HD audio. So, a maximum bitrate video with a maximum of 2.7TB, would be ~600,000 seconds of video, or 167 hours. Over 30 days, that would mean 5-6 hours of watching videos per night. If it's a household with different people wanting to watch different videos, it's certainly doable (although those people would probably need to get outside more).
I think they filter the water before distilling, to reduce the amount of particulate buildup. The specifics could be a bit mixed up for me though as it was several years ago, and I'm entirely too lazy to do a Google search.
I grew up in a place with extremely good tasting water, and unfortunately am now a bit picky about my water. I will drink most water, but always note how good or bad it tastes. And some places, like the city I work in, have tap water that is just too difficult to swallow, so I've tried a lot of varieties of bottled water.
Most store brands of bottled water taste pretty crappy to me. Dasani is certainly my favorite. I don't know who they got to design the flavor of their water, but I'd love to shake their hand. One interesting thing I noticed about SmartWater is it doesn't seem to go through your system as quickly as other waters, which I always assumed was due to whatever included salts.
One thing that also affects the taste of water is the container it is stored in. Essentially all plastics are going to bleed various bits into the water which will alter the flavor slightly. A similar thing happens with metal cans. Unless you are using all glass containers, minerals in your water are the only thing affecting flavor and healthiness.
I read an article years back about distilling machines (that you fill up jugs with) where they had gone around and tested a bunch. It turned out that on most the filters were never being changed and the machines never cleaned, so the water was full of bacteria/etc well above what was allowed in tap water. Granted, this was years ago and in California, so I have no idea how widespread that problem is today. But it wouldn't surprise me if people using those are getting less mineral, but water that is more dangerous to them.
I feel like I had a point when I started typing, but it's obviously gone way out the window now, so have a good day dgatwood.
Dude, put the pipe down. No one has said anything about how dangerous or destructive one substance or another is. The point was about the relative cultural ingraining and accessibility of various substance that might be prohibited.
First, I can't believe you're seriously trying to compare the proliferation, history, and production of alcohol to marijuana. That's like trying to compare walking with scuba diving. Both may be relatively common compared to deep sea diving, but one is still orders of magnitude more.
Second, the Declaration of Independence is written on parchment. Perhaps drafts were written on paper made from hemp, but no one knows for sure. Although, hemp is almost exclusively made from cannabis strains that can't be smoked. What would be the point?
I agree that this is a candidate for a database. One problem with data bases for researchers is that generally one does not know the right schema before hand ond one is dealing with ad hoc contingencies a lot. Another is portability to machines you don't control or that are not easily networked. A final problem is archival persistence. I can't think of a single data base scheme that has lasted 5 let alone ten years and still function without being maintained. Files can do that.
The article didn't actually ask for a way to organize data, he asked for a way to organize files. He could easily create a database that points to whatever files he wants. Populate the relevant columns, and if he wants to add another type of data to search on, add a column. It's not like you need data in every cell, you simply need data in the cells that you want to find again.
It's worth noting that alcohol prohibition and prohibition of other drugs are very different situations. For thousands of years the percentage of people who consume some alcoholic beverage was relatively high, and is tightly integrated with many cultures. It can also be made just about anywhere with just about anything. Trying to suddenly make that illegal is completely different than, say, meth.
If you really think making meth legal would improve things, then refer to studied in other countries that have legalized similar drugs.
In the US, prison guards typically aren't allowed to carry firearms. People are suppressed with basically hand to hand combat by people in riot gear. This prevents a prisoner from somehow getting a gun and going to town one everyone. Guard towers are often essentially external to the prison for this reason.
For anyone that didn't catch it in the photos, all of the officers keep their faces covered so that they can't be identified. Being linked to something specific like this is a good way to have you or your family taken out.
Somebody mod the parent up. Every time fiber comes up some yahoo mentions just putting everything on wireless. Get it through your thick heads people that wireless is a shared medium and it is simply impossible to provide high bandwidth to many users with it.
Wow, you completely missed the point of the GP. It doesn't matter if you redistribute the data in the house. The simple truth is that a single cell tower is likely to reach hundreds, if not thousands, of people. And that cell tower has to use different frequencies than those immediately surround it to avoid interference. Even if you could arrange things so that you could dump 1Gbps down a single cell, you'd still be sharing that among a hundred other people (not even counting in losses from interference, signal propagation problems, or latency).
Actually, on firmware 3.1.3, the SpiritJB application would jailbreak your iPhone connected over USB in about two seconds after clicking the jailbreak button. After that, all of the time was waiting for the phone to reboot. The website takes maybe two minutes altogether.
I bought an iPhone 4 and so set about prepping my 3G to be sold a few weeks ago. I performed multiple full wipes to various firmware versions (testing jailbreaking and unlocking), and I can assure you that iOS4 is simply slow on the 3G. In the end, I set it to firmware 3.1.3 for sell on Craiglist, jailbroken and unlocked (and managed to sell it for $200, paying for the iPhone 4 upgrade). Nobody wants a 3G on 4.0.1.
To be honest, I have no idea how you'd calculate that. That's well beyond my limited skills, but I have an idea of some factors to consider. The moon is about 30 times the diameter of the Earth from the Earth. It is in a stable orbit, but various forces are acting upon it to slowly slow it down, so that it will eventually slow to the point that it impacts into the Earth. But this will probably take billions of years. So the orbital velocity of the Earth fragments will have the greatest impact on the time it would take for it to reform.

Ah, now that is a much better argument. Although it might help to provide specific numbers regarding the most prominent surface materials of each.

What would be the major sources of radiation in the asteroid belt? The asteroids themselves?

Next up "helping orphans" will end up meaning giving them all rides on Spaceship One.
More accurately, "helping orphans" will mean giving one small group of orphans a ride in Spaceship One, and leaving the rest to roll in filth.
