As a mathematics educator at a community college I fully agree with your sentiment. However, faculty tend to dislike the use of smartphones or tablets as calculators since one can have notes on the device and use the internet. I personall

Your response is excellent. I do however have one nitpick. Social Security is not a budget expense. I know it's listed as one but it shouldn't be. Social Security is an actuarially sound self-funded pension system. There is a

I don't understand the point of your question. Can you elaborate? It is certainly true that the games were held in Nazi Germany. I don't know what pointing this out has to do with whether or not it can be morally wrong to hold t

Perhaps that is the point of the games from the original organizers' perspective but it certainly isn't the true goal of the present organizers. I do not share your view and consider it fine for someone to advocate for a boycott.

We all know that nothing, ultimately is free. However, the colloquial usage of the term means free means that the person receiving a free service means they don't fork over money specifically for that service. Free healthcare means,

There are many examples of employers (corporations) that are subsidized. Record profits, declining real wages over the last ten years for average employees, and massive increase in pay for management over the last 30 years suggest that empl

It wouldn't change that and this is a good thing. Part of being in a society is shared responsibilities. I subsidize the education of other peoples' children by paying taxes that fund k-12 education. I have no children of my own

Your view of Iraq's military capabilities and of it's military potential in 2000 is badly wrong. Iraq, by 2000, was a shell of its former self militarily speaking. The sanctions, no fly zones, and complete domination of its military in th

The GDP of the U.S. grows, generously, at 3% per year. Wealth is a zero sum game in that the 3% gain must be distributed amongst the 300 million people in the country. When wealth is concentrated in too few people it does take away from ot

Visiting North Korea as a tourist is immoral. North Korea is one of the most brutal, repressive regimes in the history of the world. Inhumane conditions abound for the average North Korean and supporting such a vile regime is disgusting.

It is grammatically correct in English to say, "I'm taking classes to perfect my English." It is more common to say, "I'm taking classes to improve my English." To me, in English, saying that you are doing something to perfect a skill imp

Why were you in North Korea? As a tourist? North Korea is probably the most evil regime in the world. Going there as a tourist supports this regime and as such is profoundly immoral.

Indeed. No mention of global warming and this omission makes me think that it was written with a specific goal in mind. That is, to justify some program or policy that powerful people are behind.

I have strong opinions on whether or not the U.S. should go to war with country A. My opinion counts as far as voting goes. I have opinions on tactics involved in fighting a battle. My opinion counts for very little because I am wholly i

There seem to be quite a few people who want to do away with tenure and seniority rules as a means of fixing a broken system. Is there any evidence that doing this would fix the system or make it better? Academic freedom, tenure, and senio

My experience working on a Ph.D. in mathematics was that the people who say, "I don't know." without any embarrassment are the smart people. They are the ones who know their stuff. My experiences since graduate have enforced this belief o

I understood your first comment to be in relation to governmental spying and neighbors (the whole world) spying. I agree the former is a serious problem and will likely have radical consequences but the latter I think won't be a problem.

We've always been social creatures and when we came out of the trees did we really have anonymity and privacy? Village life has been the norm for most of your history and I believe that anonymity and privacy aren't the norm in village life

Additive inverses are unique in any ring. The subtle things I skipped over because of the technicalities involved is how do I know the distributive property holds for negative integers. Indeed, what is a negative integer? How does one get

Note that 2575.97 also has the property that raised to the ith power gives i. There are infinitely many such numbers.

This is of course much trickier because to define z^w for complex numbers requires that one choose a complex logarithmic function. There are infinitely many choices for this. Everyone has decided to use the principle logarithm but it coul

Shoot. I lost sight of the goal. Sorry. a·0 = 0 for all numbers a Thus it is true that –1·0 = 0 Replace 0 on left hand side with (–1 + 1) to get –1·(–1+1) = 0 Now use the distributive property –1·(–1) + (–1)·1 = 0 Keeping in mind that 1·a

A lot of people are surprised that you don't use a dishwasher. This I find surprising. I don't use a dishwasher either but for a different reason. I do dishes as a fitness hack. No, you don't expend a lot of energy doing dishes. But doi

It is very interesting and worth pointing out that in the beginning of the essay says So, just in case it does any good, let me clarify that I'm not writing here about Java (which I have never used) but about hacker's radar (which I have t

I hadn't heard about a travel ban on those who owe back taxes. The articles I read after looking this up aren't as bad as it appears. The idea was to ban people who owe more than $50,000 in back taxes from traveling overseas. But that's

Let's apply your comment to a law against murder. Doesn't have much relevance does it? Your comment isn't germane. Laws always apply to the people to whom they are written to apply to. It is true that some people don't follow some laws.

Prime applies to objects in any commutative algebraic system that can't be further decomposed. I don't want to get too technical so I'm speaking in very loose terms. x^2+1 is prime over the integers but not over the complex numbers. I don

Indeed, college algebra students typically struggle when trying to tie in the concepts of factoring, x-intercepts, remainder theorem, and zeros of a polynomial. Lots of gnashing of teeth in this chapter.
