| It doesn't matter what universe you're in. All of mathematics depends only on the axioms of set theory and logic. These would be the same in any universe and do not depend on physics. Does every universe have the Axiom of Choice? How about Banach-Tarski? :) What I'm saying is that mathematical laws... |

| The relevance of academic papers exists only if you're in a job where the impact points system actually counts but you probably won't be. Don't spend too much time on your papers and thesis. The primary focus of a PhD program is on research so I am not sure why you would say that your papers and th... |

| It's not hard to get a good score on the GRE provided you are willing to put in the effort and have a decent memory. (A few months should be more than enough time.) Just take a few practice tests and if your scores are too low then use practice workbooks/software (the free software the GRE testing c... |

| ... Your "theories" don't seem to agree with much of what is known about physics. I'd really suggest learning more about what is known before you just dismiss it in favor of your own theories. Widely accepted physical theories are not to be dismissed lightly. Although they are sometimes not a compl... |

| ...if you have a mutable like a list, assignment will change the value of the object itself, unless the expression on the right of "=" is just simply a variable. You can prove this with the following bit of code: a = [1,2] b = a a = [5,6] print(b) (this will print [5,6])... No, actually it won't (t... |

| Being a proficient programmer requires a basic knowledge of mathematics no matter what language you use. It might be slightly less in some languages but often basic math is inherent to the problem you are trying to solve. In these cases, you can't avoid it by using a different language. Also, if yo... |

I think you'll need to learn a lot more before you can make any meaningful progress on this. |

| You could do that in C (I don't know if it's still legal in C11) but not in C++. I believe that's a relic of the B language? It appears so. Hopefully it will be removed eventually. Besides going through various projects on Arduinos site, I do hope to give them an important lesson. “The language C, ... |

You can omit the return type of a function (this causes it to default to int) but it's poor coding practice so fortunately it's almost never used. |

It is the same security that Auto Desk use for their laptops so I should think it is pretty secure. You c... |
