If you are a chess aficionado or know people who like this game, please help me to spread a word about my project: chessheaven.com

The girl on the picture has no connection to me (it was randomly selected).

This is just a test to see how many people will access my profile. On the 28-th of February before posting this picture there were 930 who checked my profile in 2 years and 2 month.

Please do not be disappointed with this test, rather upvote my answers if you like the joke :-).

comment Very tough inequality I cannot prove
How is this very tough? A person who learned quadratic equation (fifth/sixth - grade) is fully capable of solving it. Just substitute x^x = y and solve solve it.

comment Why is every answer of $5^k - 2^k$ divisible by 3?
Look for instance at this answer math.stackexchange.com/a/373514/50804 . Ask yourself how hard is it to type 2^3000 in any program and copy an answer? For me this will take 30 seconds in python. How much help for you is the answer? No explanation how to achieve it, but lots of upvotes.Or look at this one math.stackexchange.com/q/349806/50804 - it is hard and no one would try to do it, because why should I if I can get 50 upvotes for nothing. I afraid that in such a way a site which is supposed to be for mathematics will become a homework-solver for schoolchildren.

comment Why is every answer of $5^k - 2^k$ divisible by 3?
the thing is that a question which can be answered by any properly educated 8-class schoolchild and gives the possibility of getting huge number of points makes it reluctant for people to answer harder questions that requires some knowledge and can not be answered in 3 minutes. As @DanNeely correctly pointed, this is everywhere on SE and in my opinion this might hurt the site in the future

it is so sad that questions which are really easy and understandable are getting so many upvotes, but questions that really requires understanding are staying in a shadow. This is one of the examples....

comment How can one prove that integral can not be solved in transcendental functions?
@sdcvvc thanks, the first answer is actually a really good answer, but, rather a complicated one. About the second - this is what I have mentioned in the part about Liouville theorem.
