"But the IRS determined that it would restart the clock on [tax] credits if a wind farm “repowered” its turbines—replacing equipment with newer parts. So, despite the expected two-decade lifespan for turbine blades, wind farms began replacing many that remained in good shape years early."

America, where no perverse incentive can be allowed to be left unexploited :(

There's a lot of talk about how A.I. can be used as individual language tutors on a large scale.

Is there any reason why this could not work for mathematics too ?

The PLATO system for so-called "programmed instruction" was available in the 1970s, IIRC. Meanwhile, math pedagogy, AFAIK, tends to more rigorous reference to "scope and sequence". These seem compatible even without AI, and if only to better identify gaps.

I lucked out and took these courses in order:

1. Algebra-based "just apply the formula" d=vt, y=v_0*t+gt^2/2.

2. Calc I, where the previous formulas now made complete sense and served as mnemonics.

3. Calc-based stats, calc-based physics.

I'd recommend this to anyone.

Referring to an algebra-based physics class?

Now also move the notion "include the units and they must work out" back to intro algebra classes, and kids could have a superpower in solving word problems.

There's only so much you can blame the pandemic for. You can say that you weren't given proper instruction, but that excuse does not go very far when you have the internet available to you. I've seen the resources available, and even the most popular are good enough to get you through any 'college' level course. You hardly even need to be an expert at evaluating quality to get there either.

But really, universities should grow a spine and reject students who do not meet their supposed 'high bar'.

I do find it really strange for someone to ace "honors physics" to then fail qualifications for intro calculus. Seems that credit is highly suspect.

Famously, there can be "plug in the numbers" physics. Zero conceptual understanding required, And then all you need to know about fractions is to "divide" that entry on the calculator.

For example, in a PSSC high-school physics course, I remember adding four or five terms when analyzing a calorimetry experiment, with no awareness of adding compatible (same units) energy-related terms.

In some ways a high-school student might be better served in a conceptual physics course, if competently taught.

Oh I know. There is an easy solution to this. Just sell the information for Bitcoin and use Bitcoin as a store of value and then in the future buy the information back using the store of value feature of Bitcoin.

(Cough, someone still has to store the information.)

So the DSN has some properties of cooperative multitasking ... what could go wrong?

pro-kythera commented on Why do shared hospital rooms not violate HIPAA?   law.stackexchange.com/que... · Posted by u/oatmeal1

How does HIPAA compare to FERPA?

My understanding is that FERPA is similar to HIPAA, except for college scores and enrollment information instead of medical records.

But there’s a rule in FERPA where you explicitly can’t leave a stack of exams and let students pick them, because it exposes students to others’ scores. Another rule is that you can’t associate a students exam with their student ID even if it’s a sequence of numbers, because the id is public information, but you wouldn’t expect someone to remember someone else’s id.

(I specifically remember some professors not following the exam rule, probably because they didn’t know or perhaps it didn’t exist yet. I don’t know if anything happened to them but I suspect if anything, they were simply asked to not do that in the future.)

As a comparison, at my Uni in the 1970s individual grades were posted along with corresponding social security numbers.
