Hold on a minute, if graphene is 100 times stronger than steel and 2 atomic layers can be "bulletproof" then that would mean a sheet of steel 200 atoms thick would be equally bulletproof? That would be 1000 times thinner than aluminium foil, what sort of weedy bullets are they using?

@newtboy said: "a 3' rise, which is all but guaranteed by 2100 under the most optimistic current projections."

Lies.

The most recent IPCC report(AR5) has their section on sea level rise here:
https://www.ipcc.ch/site/assets/uploads/2018/02/WG1AR5_Chapter13_FINAL.pdf

In the summary for policy makers section under projections they note: " For the period 2081–2100, compared to 1986–2005, global mean sea level rise is likely (medium confidence) to be in the 5 to 95% range of projections from process based models, which give 0.26 to 0.55 m for RCP2.6, 0.32 to 0.63 m for RCP4.5, 0.33 to 0.63 m for RCP6.0, and 0.45 to 0.82 m for RCP8.5. For RCP8.5, the rise by 2100 is 0.52 to 0.98 m"

And to give you maximum benefit of doubt they also comment on possible(unlikely) exceeding of stated estimates:" Based on current understanding, only the collapse of marine-based sectors of the Antarctic ice sheet, if initiated, could cause global mean sea level to rise substantially above the likely range during the 21st century. This potential additional contribution cannot be precisely quantified but there is medium confidence that it would not exceed several tenths of a meter of sea level rise during the 21st century. "

So, to summarize that, the worst case emissions scenario the IPCC ran(8.5), has in itself a worst case sea level rise ranging 0.5-1.0m, so 1.5 to 3ft. They do note a potential allowance for another few tenths of a meter if unexpected collapse of antarctic ice also occurs.

Let me quote you again: "3' rise, which is all but guaranteed by 2100 under the most optimistic current projections"

and yet the most recent collaborative summary from the scientific community states under their most pessimistic projections have a 3 ft as the extreme upper limit...

You also did however state "IPCC (again, known for overly conservative estimates)", so it does seem you almost do admit having low opinion of the scientific consensus and prefer cherry picking the most extreme scenarios you can find anywhere and claiming them as the absolute golden standard...

I'm not impressed. She has the sheet music right in front of her.

Oh, I was so hoping for a giant sheet of glass right at the end.

Because it's meant to replace a human. If it's wheeled, or something, then it can't go up stairs effectively.

I mean, it's already shitty enough at the job. Seems to take a long time even with the edits in there, not to mention it seems incapable of installing anything other than full sheets on a perfectly flat wall made specifically to dimensions it was pre-programmed for. It'll be a long time before anything like this is actually taking jobs away in significant numbers.

I disagree. Pinpointing the problem isn't very hard if you have some idea of where to look.

As someone who was 'coming of age' in my profession when No Child Left Behind (NCLB) and its successor the Every Student Succeeds Act (ESSA), I can provide some insight into how these policies have been enacted and how both have been detrimental to the public education system as a whole. The former is a GWBush policy, and the latter is an Obama policy meant to mend the original law, so both liberals and conservatives are to blame to some degree, but both are based on the same philosophy of education and teacher-accountability.

There are some other mitigating factors and outside influences at work that should be noted: gun violence, the rise & ubiquity of the internet, and universal cell phone availability, all mostly concentrated in the past 10 years that play a large role. Cell phones, for example, are probably the worst thing to happen to education ever. They distract, they assist in cheating, they perpetuate arguments which can lead to physical altercations, and parents themselves advocate for their use "what if there's an emergency?!?!"

The idea of "teacher accountability" is the biggest culprit though.

Anecdotally, I've caught people cheating on papers. A girl in my honors English class basically plagiarised her entire final paper that we worked on for close to a month. The zero tanked her grade, which was already floundering, and the parent wanted to meet. I'd rather not go into detail to protect both the girl and my own anonymity, but suffice to say, all of the blame for this was aimed directly at me. How? Well I (apparently) "should have caught this sooner and intervened." Now, the final in that class is 8 pages long, I have ~125 students all working on it at the same time. but my ability to check something like that and my workload are beside the point. I'M NOT THE ONE WHO COPY PASTED A WIKIPEDIA ARTICLE AND DOCTORED IT UP SO IT COULD SQUEAK BY THE PLAGIARISM DETECTOR (shows she knew what she was doing, IMHO). Yet, I'm still the one being told that I was responsible for what happened.

Teacher-accountability SOUNDS like the right thing to do, but consider the following analogies

--Students are earning poor grades, therefore teachers should be demoted; put on probationary programs; lose some of their salaries; and if they do not improve their test scores, grades, and attendance; be terminated from their positions.

as to

--Impoverished people have poor oral hygiene/health, therefore their dentists should be forced to take pay cuts from insurance companies. If the patients continue to develop cavities and the like, the dentist should be forced to go for further training, and possibly lose his practice.

I have no control over attendance.
I have no control over their home life.
I have no control over children coming to school with holes in their shoes, having not eaten breakfast.

@Mordhaus the part about money grubbing could not be further from the truth.

I'll be brief b/c I know this is already too long for this forum, but Houton Mifflin, McGraw Hill, Etc. Book Company is facing a shortfall of sales in light of the digital age. It may be difficult to blame one entity, but that's a good place to start. They don't sell as many books, but guess who produces and distributes the standardized tests and practice materials? Those same companies who used to sell textbooks by the boatload.

When a student does poorly, they have to retest in order to recieve a diploma. $$$ if they fail again, they retest again and again there is a charge for taking the test and accompanying pretest materials. Each of which has its own fees that go straight to the former textbook companies. See: https://www.pbs.org/wgbh/pages/frontline/shows/schools/testing/companies.html

In short, there is an incentive for these companies to lobby for an environment where tests are taken and retaken as much as possible. Each time a student has to retest that's more $ in their pocket.

How can they create an enviorment that faccilitates more testing? Put all the blame on the educators rather than the students.

That sounds a little tin-foil-hat conspiracy theory-ish, but the lobbying they do is very real: https://www.washingtonpost.com/news/answer-sheet/wp/2015/03/30/report-big-education-firms-spend-millions-lobbying-for-pro-testing-policies/?utm_term=.
9af18f0d2064

That, combined with exceptions for charter/private schools where students have the option to opt-out of said testing is skewing the numbers in favor of all of these for-profit companies: http://sanchezcharter.org/state-testing-parent-opt-out/ << one example (you can't opt-out in a public school, at least in my state)

@bobknight33 idk if i'd call business-minded for-profit policies "liberal"

No, it's a thing where people water their windows to make a sheet of ice they can break through that looks like a window...but you need to roll the glass down before sticking your head through...unless you're as hard headed as I am.

And what is that other paw doing under the sheets?

A different type, but yeah, they can be found under just about every pot these days. Every somewhat covered crevice seems to harbour some, really.

I had only seen singular examples in damp corners until maybe 3 or 4 years ago when they started popping up in ever increasing numbers. Nowadays, go outside and lift any pot, you'll find 5+ of them scrambling. When I pulled up the edge of an old sheet of rolled roofing the other day, there were dozens of them.

Just from a quick goggle search. First thing i came across, and that is all you will get as it's already better then someone saying something is fact without the willingness to back it up. Although i assume you got that stat somewhere and would be interested to see where from.

"As the National Center for Women and Policing noted in a heavily footnoted information sheet, "Two studies have found that at least 40 percent of police officer families experience domestic violence, in contrast to 10 percent of families in the general population. A third study of older and more experienced officers found a rate of 24 percent, indicating that domestic violence is two to four times more common among police families than American families in general." "

The info sheet they reference http://womenandpolicing.com/violenceFS.asp#notes

I find it much more sad that people are willing to delude themselves with placating mythos that can't stand the slightest critical examinations than I find the fact that there's almost certainly no god(s) by any definition. Lack of a supreme being is not a scary thing to me in the least, but a capricious, judgmental, incomprehensible, vengeful god ready to cast immortal souls into hell for eternity over small rule infractions is horrifying.

Reality is scary. I get why people would hide their heads under the safety blanket of religion(s), I just disagree that it's any more useful against reality than hiding under a sheet is against home invaders. It might make you feel better because you can't see them, but that's all (unless they are as dumb as the bugblatter beast of Traal, who thinks if you can't see it, it can't see you).

I feel bad for your uncle, who it sounds like believes in god out of a fear instilled in him as a child. Consciously, it sounds like he understands it's an irrational belief, but fear makes people do irrational things all the time. Fear is the mind killer.
