comment Is there a power of 2 that, written backward, is a power of 5?
seems somewhat similar to a conjecture of Erdős and Graham that the base 3 expansion of $2^n$ avoids the digit “2” for infinitely many $n$, see also some analysis by RJLipton

comment How to determine the number of directed/undirected graphs?
it is possible the homework is asking for the answer of number of "random graphs" disregarding identical graphs, a simpler answer using the powerset of combinatorial C(n,2). a correct answer involves graph isomorphism.

comment Mathematical concept for formal languages
there are many applications of formal languages & its a very broad question in CS....

comment Are problems about finding the next term of a sequence mathematical?
yes and no! at some level this is a very deep question studied in philosophy called "the problem of induction" and in other sciences also (but havent come across nice survey). eg see Popperian theories about falsifiability. in general no finite set of samples can ever define an infinite rule. it also shows up in statistics, machine learning, theorem proving etc!

comment Interesting mathematical problems for 1st year university students
very disappointed this hot question got closed. can it be moved to meta?

comment Why do mathematicians sometimes assume famous conjectures in their research?
conjectures are something like "theoretical hubs" and math is a large graph of conditional/"if/then" statements connecting them. if many conditional statements can be connected to a hub, that is an "interesting" and "significant" node either way whether true or false.

comment Application of computers in higher mathematics
see eg following related essays with many leads/refs/se Q/As, great moments in empirical/experimental math & adventures/commotions in automated theorem proving. the main challenge of computerized math intelligence is undecidability (discovery dating to Godel) but it is not inconceivable there could be major advances

comment Are mathematical articles on Wikipedia reliable?
see also elementary mathematics on wikipedia by prof Riskin with similar biting criticism

comment Are mathematical articles on Wikipedia reliable?
they might be generally reliable but are they understandable? unf a case can be made that style is challenging in collaboratively edited documents, and imho many wikipedia math articles often tend to be difficult to follow compared to similar book accts based on minimal exposition and heavy technical/formal emphasis.... & feel they tend not to define math terms well before using them etc.... many misc/prominent issues related to comprehensibility! similar complaints on misc net forums eg reddit

comment algorithm for traversing a fractal in a “maximally ordered” way
addendum: this might be related to pathfinding algorithms eg A*. have they been applied to fractal traversal? (theres a lot of recent research on online versions also)
