I know that the end product of a master's thesis can be not only a scientific finding, such as the relationship found between certain variables, but also the business plan, or even a concept for a new product or service.  What can be the end product of my PhD dissertation? My idea is to actually to carry out a research project, in other words, to have some 100-200 interviews, collect some qualitative data etc. But can a business plan / model be my actual finding? Can I make a business case, develop that something [and later sell it as a finished product], but still call this everything a PhD by turning the idea into a scientific problem, and having a product as a result / finding?  Can a PhD be an applied research?  Working title: Development of an innovative marketing product (or service) for tourism industry, and understanding a demand for such a product (or service).   Field of study: Marketing / Innovation / Tourism
Few days back while attending a thesis defense, one Professor was asking the defender why does he think, he deserves the degree. I was wondering since then, is there really any general answer for that? or the answer should be given describing my own work and then emphasis them how it is important for research field?  I asked the question here to know your opinion about it and to list down what could be the possible answers to this question.
How to prove $x^{n}$ is not uniformly continuous How to prove $x^{n}$ is not uniformly continuous on the interval $[0, +\infty)$? I found this pretty good small research, but I am still concerned about "regular usage" in life, say, when I am talking in the office, especially because of this comment:     To me: Stone is something you can pick up with one hand (for   throwing). A rock takes two hands. Can the Surface Area of a Sphere be found without using Integration? When we were in school they told us that the Surface Area of a sphere = $4\pi r^2$  Now, when I try to derive it using only high school level mathematics, I am unable to do so. Please help.

A (highfalutin) word for a highfalutin word? To illustrate the question, badroit used the word "meretricious" meretriciously.   Is there an English word that describes highfalutin words like "meretricious" that are (gratuitously) used in place of better-understood words like "garish"?  The word may or may not be self-describing. Calculate difference between two dates (number of days)?

Take into consideration the list: [{'name':'Homer', 'age':39}, {'name':'Bart', 'age':10}]  When sorted by name, it should become: [{'name':'Bart', 'age':10}, {'name':'Homer', 'age':39}] What is a substitute for red or white wine in a recipe?

Transforms moving around the 3D cursor? I think I accidentally pressed something to make it like this:    See how the XYZ arrows are at the 3D cursor instead of those vertexes I've selected?  How do I fix that? Whenever I select on a vertex or something, those blue, red, green arrows would always be where I selected, now it just keeps going to the 3D cursor. why ls reports a huge file and du does not? I'm using Ubuntu 17.10 with GNOME 3. How can I show all open windows of a certain application using the sidebar (aka Ubuntu Dock)?

Proving that $\lim_{n \rightarrow\infty} \int_{0}^{\frac{\pi}{2}} \sin(t^n) dt =0$ It is clear that $\lim_{n \rightarrow\infty} \int_{0}^{1} \sin(t^n) dt =0$. (which is not what is to be proved here)  I don't know how to proceed with the remaining part of the integral ie $\lim_{n \rightarrow\infty} \int_{1}^{\frac{\pi}{2}} \sin(t^n) dt$ (I tried substitution and partial integration).  Can anybody give me a hint ? How can we prove that a binomial coefficient $n\choose m$is divisible by the ratio of $n$ and $\gcd(n,m)$? How should I structure my URLs for both SEO and localization?

Splitting lines with points while maintaining other dissolved lines? I am on ArcGIS Desktop 10.2. I have a line feature class of a stream network. I also have a point feature class along the main stream (line) where a catchment enters that stream. I have dissolved my whole streams layer into one line feature and want to split this feature at the points.    However, when I use the  tool, the lines that don't have a point splitting them are still being split at the intersection of two streams.    Why did this line not stay as one feature with the other lines on that side of the splitting node and how can I prevent this from happening?
