I was today's years old when I realised that "we" give developers an object called the Advanced Encryption Standard which is not an encryption algorithm (but a pseudorandom permutation) and then we are shocked when we encounter yet another ECB mode in the wild. 🙃

Cryptographers don't gossip, they exchange side-channel information.

Me upon arriving in Germany:

-I don't want to be like those people who only hang out with foreigners. I'll primarily seek out Germans and make German friends.

Me one year later:

-Where is the next international people event in Germany?

The word "inequality" is now blacklisted by the NSF. Mathematicians in shambles.

The most important mathematical tool is perseverance. A thing math teachers are paid to erode.

The second most important mathematical tool is creativity. A thing you are forbidden from doing until you have committed to the subject.

Hey #MathSky, I have questions:

1. WHAT are these little buttons for?
2. Have you EVER actually used them?
3. Have you ever seen ANYBODY use them?
4. WHY are they still around?
5. In what year do you think they will finally go away?
6. What other things in life are like this? (I can think of a few)
