"They feed each other."

I'm not deeply educated on farming (my father in law is a farmer, but that's him). But this is a serious red flag. The nutrient structures come from the soil, with synthesis energy supplied by the sun. When the crop is harvested, the atomic structure in those harvests leave the fields. Ultimately, it came from and leaves the soil and must be replaced. I am sure there is useful coexistence between plants, but that cannot in principle solve the soil nutrient regeneration issue. The idea that plants somehow "feed each other" is an agricultural perpetual motion machine.

In my experience working with students, not a single person in the world has trouble with Calculus. The problem is students stop using basic math skills and reach for a calculator until they lose any number sense. Once the number sense is gone, algebra and trig become impenetrable. And Calculus is almost all algebra and trig, so out goes any hope of Calculus. I remember grading Calculus papers for a professor years ago and over half the class couldn't get even basic arithmetic right (and they were allowed to use a calculator!) Over half dropped, and it was not the professor's fault.

Calculus isn't hard if a person understands how numbers, algebra, and trig work. Calculus is a living hell otherwise. What these articles show is how poorly some college students understand basic algebra, trig, and arithmetic. And that is really what Calculus is "weeding."

I have students that can't divide 12 by 3 or subtract 7 from 6 (it's -1). It is an absolute nightmare to teach a kid basic manipulation of algebraic expressions, like combing like terms, when they can't do basic arithmetic without a calculator.

When it gets to that point, they can't even spot obvious errors with data entry. I've had students try to convert 2/5 to a decimal and write down 2.5. They lack the basic number sense to realize splitting two pizzas between five people could not possibly result in everyone getting 2.5 pizzas. It makes learning (and teaching) algebra a nightmare for everyone.

So the solution for some is to teach n-solve. So then I end up with Geometry students who can't handle basic algebra but managed to get an A in algebra 1. I used to grade Calculus papers as an undergraduate assistant, and I recall that half the class couldn't do basic algebra (and ultimately dropped). When I talked to the professor about my astonishment, the professor said that calculators are all curse and no blessing.

An issue with education is it's easy to have an opinion with what sounds like a good argument, but just doesn't line up with reality.

On numerous occasions I have seen a rather contradictory juxtaposition of beliefs:

1. The death penalty is immoral, and part of the reason is it's impossible to find a painless way to execute a prisoner.
2. Assisted suicide is highly moral, because it allows a painless death instead of suffering.

Anytime I see an article like this, it comes to mind. On a more on-topic note, I wonder about the ethics of marketing in the context of assisted suicide. Afterall, death-pod-corporation stands to profit from increasing suicides.

Years ago my dad went on a stock exchange kick. He thought he would invest in the "next big thing" and hit it rich. When he would take about the latest "promising news" from a company it slowly started to occur to me that it was a sham intended to lure penny stock investors. My dad ended up losing about $30,000 in the long run, because inevitably all of the "amazing break throughs" didn't pan out. I highly doubt TAE has found anything other than a break through in robbing middle aged men having a mid life crises.

I'm not sure if you're serious.

First, Maxewell's Equations are differential equations. As in, algebraic equations with Calculus thrown in. And if you want to study differential equations, you'll probably want to extract eigenvalues or eigenvectors from the Jacobian computed at a fixed point, which is a generalization of the derivative. And I really don't want to tell you what a phase space is. No really, what do you think those arrows are? And any actual use of a manifold (aside a 101 introduction for laymen) is going to involve continuous transformations. "Continuous," as in, that thing from Calculus again, because "open sets pullback to open sets" implies an epsilon-delta can be found in the real variable case.

You're like a deep sea fish that doesn't believe in the ocean. A true marine marvel.

More realistically, he didn't have a good grasp of algebra going into the class.

It's not the Calculus that people struggle with, it's the algebra and trigonometry. I think a nurse could get by without understanding how to get a line of best fit using derivatives, or how u-substitution accounts for the empirical rule, but without a good grasp of algebra it's impossible to understand probability and statistics.

I partially agree. Instead though, I started buying into consoles later in their life-cycle. At that point, the popular launch titles are cheaper and used games are more abundant. I haven't bought a brand-new AAA title in years, though, because $60.00 is just too pricey for my income level.

Or Apple could have them sent to secret iPhone manufacturing facilities to have their organs converted into the latest "Samsung supplied OLED screens."

Conspiracy, or FACT?

I don't care about computer illiterate, I personally don't feel like having "another thing to do." I'm constantly hassled with software updates that switch up my routine, and at this point I'm starting to just prefer paper. After all, it isn't "just" Google that wants to dream up the next great paradigm to force everyone else to learn. I'm tired and busy, and installing some stupid update and re-learning it is ANOTHER piece of crap I have to deal with. It feels like every so often, I launch an app and am greeted with an "easy" 5-step tutorial to the "new exciting changes" that moved all my buttons around AGAIN.

Actually, it's free to set up HTTPS if you use letsencrypt.org. It takes roughly an hour of research to get it working, give or take depending on your current server setup. There are only a couple of gotchas: one, you have to make a certificate signing request file, .csr, which is easier on Linux than Windows. IIRC you can do it with Docker on a Windows machine. The second catch is, there are actually two files you have to put on your webserver, one is the private key, but the other is some "security key history" file that says where the security key came from. I can't for the life of me remember how that was setup, but it gave me some ugly unexplained "not secure" error in Chrome until some furious Googling surfaced the issue.

Oh, and the third catch is, try to make the links embedded in your site use https, since an http frame embedded in an https frame isn't secure by virtue of the parent frame. Anyway, if you take the dive, expect a few headaches and unexplained "this page is not secure" experiences before you hammer out the bugs. But it's doable in a single weekend for free, and you get a nice professional looking https bar as a bonus.

Also, some managed cloud services can turn on https for you with the push of a button, so it could be worth digging around in your settings if you're using a high level CMS / cloud host.

Statistical analysis by unbiased machine learning systems, derived via data on social media platforms including Twitter, that Trump would win. The difference between the correct and wrong predictive systems is that one was just left-wing echo chambers regurgitating Hillary propaganda, the other was a genuine unbiased prediction engine. All these departure protests are is more left-wing bullying to manipulate social media into promoting their bull crap.

    "You seem to be confusing solar energy (as you put it) with solar power generation equipment."

Here I was thinking we had electric lines between the United States and China to give us their solar power exports. Boy I sure am enlightened now.

  "Your equivalence is false"

No it isn't. Existing equipment requires continual maintenance and replacement, and new installations are frequently needed to account for growing energy demands in the population. More than that, ramping up nation-state scale production of equipment isn't something that can be done overnight. Being cutoff from OPEC would have similar consequences as being cutoff from renewable energy for dependent nations without their own production.

The predominate exporter of solar energy is China. Now I don't care if you want green energy or not, the net effect is the relocation of U.S. energy dependence from OPEC to China. Now, given Saudi Arabia has basically crapped all over human rights with zero international challenge as a result of their control of energy, it should be clear to everyone the dangers of such a situation. And what we see is a long line of Chinese donations to the political party which keeps shipping U.S. energy to China "in the name of the environment" and "free trade": These aren't new claims, e.g. from 1998: http://www.nytimes.com/1998/05... What's fantastic is when Republicans point this out, they're just labeled "science deniers."
