19:41 UTC Revision 1 . . . . Marcin Borkowski – No, I will not write about the famous book by Lakatos. I will write about proofs, or rather “proofs”, since what we see in math journals are often not really proofs. This week I read two texts by two different people, which confirm what I’ve been thinking for some time already. I have to say that reading through papers in math journals can be pretty frustrating. And it’s not because I’m stupid and can’t understand the proofs (well, this, too, sometimes), but the main reason is that there are so many published papers with errors.
