Normal ice that occurs on earth floats. At high pressures and low temperatures, that might be expected out there, there are a large number of other allotropes that do not.

The price of diamonds is artificially inflated. Even gem quality stones are not that rare. The diamond industry keeps the supply low to keep the price up.

Not my comment

We are talking about people who are nearly totally disabled. Want to work under those circumstances is a very questionable concept. The lack of empathy to the handicapped that some people show is hard for me to believe.

She could still speak but could not eat. I have no idea what she wanted only what she got.

Hawking was a brilliant physicist. The loss of what he might have accomplished with better health is a loss to us all. My sister was a hospital clerk. Most people's work is something they do to survive nothing more. I am in favor of anything that allows handicapped people to do more, but work is not life.

I have to agree. If he cannot speak is certainly physically disabled in many other ways. ALS is incurable and the life expectancy of someone suffering from it is short and the quality of life is poor. My sister died of it, and she required full-time care for a several years. Fortunately, I was able to afford it for her. Her early death still pains me, but in the end, I have to consider it a release.

Microsoft is disabling this software for which people have paid, because it is too much trouble to update the license certificate? Meanwhile, they keep pushing AI support that I neither want nor need.

Neither can another human being. If you want that information preserved, it has to be done by the original author. The same is true for other forms of information presentation (books, etc.).

Yes. A "Master's Degree" generally means in this regard an MBA. Get one from a big-name university and it will mean something, get one from a local college or degree mill and it will not. In this case, it is not about what you learn (which is probably about the same), but about the contacts you make with other students and the professors. The actual value of what is taught is not significant enough to justify the higher pay that people with the degree expect. Two years of practical job experience are more valuable.

Nobody is that good.

Grade cutoffs are inherently arbitrary. There is no real difference between an A-- and B++. Someone is always going to be the lowest A and the highest B and that is just the way it. I once took a course (a non-major elective at that) where the professor gave a class of about 60, one A, four Bs, and rest Cs and Ds. Needless to say, many people were unhappy so grade deflation can also be a thing.

This is college we are talking about. Homework is not really a concept there. In some courses, you might be asked to write a paper or read and summarize the literature on a subject, but it should not be anything with a set answer. However, too many professors are lazy and give the same tests year after year. Fraternities and similar organizations keep files of old tests, that allow their members to effectively cheat.

Make the questions harder or teach more advanced material. If most of the students are getting 95% either the test is too easy or the course is not challenging.

Interesting. I would have thought that for this sort of project all of the information would be clearly specified before production began and checked and rechecked. After all this subcontractor was apparently chosen because they had an excellent history in this type of work.
