I get the feeling that the Professor is the one with the issues. Not the students.
From my experience, it sounds like it is his first time with undergrads.
I have found professors who are fresh out of the trenches often fail to comprehend, the following.
1. These students are taking more than just His class.
2. Chances are the class is required. Meaning most of the students don't have too much interest in the class.
3. The students are filled with other concerns then just that class. Finding a girl/boy friend, trying to keep on on what he should socially be.
4. Because he specialized in that topic for so long, there isn't any empathy on the fact that people just don't get it, the first time.

When students are in such a class, they will collaborate with each other so they can piece together all the stuff they learned, this is often done with homework assignments, this can be considered cheating. Being that these are student, who are paying for an education, if they feel like they are being bullied by the professor they will talk back, to defend themselves.

Why bother converting it at all?
Americans who have even a passing interests in real science knows about the metric system of measurement.
Are able to do at least rough conversions enough to get the idea of scale.
A Meter is about a Year.
A Kilometer is about 6/10 of a mile.
A Centimeter is about 1/2 inch

For understanding science stories this level of rough accuracy is good enough for them to get an understanding of scale.
Of course if you are using real science.
A. You wouldn't use Discovery News as a source.
B. You would think in terms of metric for all measurement.

I think it was suppose to be 200 meters.
As the earths crust is only 30 miles thick.

The current dogma is that memorization is bad. Educators learn in college that memorization is the worst tool for students, and will cripple their minds. Mental math requires memorization of multiplication tables, which has long been established in educational dogma as bad. Learning to memorize facts has been established as incorrect and harmful in educational theory.

The theory is wrong.

CustomerP are generally too cash poor to be good customers. They are going to nickel and dime you for any project that you do for them because they are either too cheap to invest in newer technology or too poor to do so.

Latest statistics indicate that Internet Explorer has less then 15-20% of market share, with versions older then IE 10 being just 2.5% of the market. Looks like IE 6 is under 1% now.

It was similar arguments that massively hampered the adoption of Linux, Netscape/Firefox, .... Too few users, too cheap, expecting too much frree stuff. No money to spend.

It's one of the reasons general adoption took - and is still taking - so long.

It's also one of the reasons that companies that DID support them ended up with an edge on their competition, becoming some of the big-name companies in their markets.

Becoming market-dominant and ubiquitus includes not dropping substantial chunks of customers because you perceive them as "marginal". If you support 90+ percent of the market and your competition supports 70%, you keep getting little extra advantages. The outcome of competition is driven by tiny margins.

The brain in the jar being fed false/artificial stimulus has been around for much longer.
However we have no way of testing that you are just a brain in a jar, or an actual person. Because it comes down to what our senses tell us.

I guarantee you more wheat will have more nutritional value. It's going to be more because it has more calories. If you're banking on micronutrients in wheat... your diet is wrong; even brown whole wheat and brown rice are not significant sources of anything, with brown rice containing like 0.005%DV iron and white rice containing 0%DV (so you'd need 12,000,000 kcal from brown rice to hit 100%DV iron).

Plants don't store up nutrients for your benefit. Potassium deficiency in the soil will stunt plant growth; plants store calcium, magnesium, and potassium because they need it to grow. Blueberry foliage turns red when the soil is cold because blueberries cannot effectively migrate potassium from the soil, and so cannot produce sugars via photosynthesis. Most plants will fail to grow without potassium content in the leaves. Magnesium deficiency will prevent the development of chlorophyll. All kinds of processes require all kinds of metals and vitamins and enzymes.

If it grows, it's full of trace elements.

65-pound dog can die from 3g. A husky weighs 35-50 pounds. Toxicity at higher doses occurs in the canine liver; at low doses, a massive insulin reaction occurs, causing a blood sugar level drop resulting in effective starvation.

A 12oz bottle of soda has 30-60g of sugar in it (I've drunk sodas with 61g in a 12oz serving). That would be 15-30g of Xylitol, potentially as high as 1g/oz. Small and miniature dogs are currently in vogue, and would quickly die from as little as half a gram (a few laps); a medium-size dog could lap up enough soda for a fatal dose in 3-5 seconds.

Dogs are popular pets.

Any energy source comes with a trade off.
The problem is we don't have leadership that will accept this fact and say we must sacrifice this to get that.
Right now when ever there is an issue, our elected officials will just throw the baby out with the bath water.

I mean if you are going to take a 75% cut, well then you can afford to spend the fucking time curating your shit. If they are going to charge that kind of cut, they can afford to have people review the content. Given that they are taking a much larger cut than the dev, it should stand to reason that goes to paying for some work on their part.

Have it where you submit a form to Valve with what your mod is, what it does, etc. They screen it to make sure it sounds like a reasonable idea, and then send you stuff to sign where you declare that this is your work, you aren't violating copyright, you've paid commercial licenses for software used on it, etc. Once they have that, mod gets submitted and then it goes off to Bethesda for QA. They test it to make sure that it does what it says, doesn't crash the game, and so on. Maybe even help fix bugs possibly. If that's all good Valve does a final check to make sure they don't see any copyright violation (maybe an automated system that flags and then a human checks i there are flags to see if it is legit) and it then gets posted.

If they were doing something like that, then ok maybe there's some justification of the price. Ya there's a big cut getting taken, which means higher prices, but you are getting something more along the lines of paid DLC. QA like that might be worth it.

However they were just letting anything and everything get posted. They were treating it with the same indifference as the rest of Steam, which is just not ok.

At first glance, all of these technologies are implemented solely for the purpose for bring in more money to the government.

But I'm sure I'm not being at all cynical enough and probably a bit of Tin Foil Hat theory wouldn't be inappropriate.

We have cut and cut and cut. Some kids are "gifted", and get to take Calculus; algebra is no longer standard curriculum. English grammar has been cut back. Latin and Greek are too hard for the less-special of us.

The school system is targeting "success", in that "we can all succeed", by lowering the fucking bar.

Aspartame has problems for some people (like my wife and brother-in-law) and not for others (like me).

Sucralose has problems for some people (like me) and not for others (like my wife).

Seems to me the thing for Pepsi to do is to bring out another formula - with a different name - using Sucralose, put them in the stores side-by-side (they get a LOT of shelf space to play with), and let the customers decide.

Changing the formula of an existing brand strikes me as a stupid move. I suspect Pepsi is about to have it's "New Coke!" moment...

Oh well, Diet Coke is still better anyways.

The radio story where I first heard about this claimed that Coke was considering doing the same to Diet Coke.

The bit you're apparently not grasping is something called a spatial light modulator. ... Couple it with a microwave radar or ultrasound sonar, and you can track individual raindrops and then cast shadows on them.

Then construct an object that appears to the system to be raindrops and you can put an invisible obstacle in the road. B-b
