I love kernels and images… generally vector spaces are the best. One divided by zero equals infinity. I love using ξ and ζ in proofs, because they’re so easy to draw. Every statement in a proof which contains “clearly” is blatantly obvious to me.
These are just some of the quotes posted on the Facebook page ’Things math students don’t say’. This page (https://www.facebook.com/pages/Things-Maths-Students-Dont-Say/381016922016758?fref=ts), that was created in May of this year seems to perfectly reflect funny thoughts of many mathematicians from around the world. But not only math students can identify with the quotes, as an econometrician you will probably find many recognizable thoughts as well. By now, already more than 7.000 people have liked the page, and this number is still growing. Among these likes seem to be quite some econometricians as well. How could it be otherwise after all those analysis and algebra courses after all?
Besides this page for mathematicians, there are many other interesting similar pages. For example the page “Things Physics students don’t say”, containing quotes as “I think my general relativity exam was relatively easy”. Or the page “Things Biology students don’t say” with quotes like “No, of course I didn’t fail to get into Med School”. The same page for Economics students exists as well with lines such as “The substitution effect is the first thing on my mind when I have to choose between Dominoes and Pizza Hut” and “I tell my boyfriend/girlfriend I don’t want to spend more time with him/her due to the law of diminishing return.” The historians come up with “Ah, shit, I forgot my calculator,” and the chemists with lines such as “I never keep my lab coat on as long as possible to show people how cool I am…”
But besides all these Facebook pages, there are some more interesting subject related websites, for example this one: http://www.pickuplinesgalore.com/math.html. It contains many funny pick up lines related to math. Some great quotes are “I wish I was your derivative so I could lie tangent to your curves”, or “My love for you is like a concave up function because it is always increasing”, or “I don’t know if you’re in my range, but I’d sure like to take you back to my domain.” These lines will probably not help you in any bar, but some students will certainly be really impressed by all these one-liners. Anyway, good luck with them and enjoy exploring more on these pages!
