Once upon a time, not long ago, the math world fell in love ... with a chalk. But not just any chalk! This was Hagoromo: a Japanese brand so smooth, so perfect that some wondered if it was made from the tears of angels. Pencils down, please, as we tell the tale of a writing implement so irreplaceable, professors stockpiled it.

Tune in and experience his deeper side live from Audio San Francisco The performance showcased the new direction of his sound, integrating analog technology into his deep progressive house. With minimal visual distractions, the focus lays directly on the music. As the site of one of his favorite past Mixmag events, Le Youth felt Audio would be the perfect place to exhibit this new experience. Inspired by artists like Eric Prydz, Lane 8, Joris Voorn, and Stephan Bodzin, his sound continues to develop. His latest track, ‘Obvious’ delivered a collaboration with Adam Rom that blended orchestral notes with dance-pop. The instrumental ‘Aquiver’ EP was released last year on Lane 8’s This Never Happened label which Le Youth has said is his “best work to date”.

This slow death is what allows for change: take control of it, encourage it. Murder yourself to make room for yourself.

Spend time prototyping your app on paper and really working on the human interaction before you write a line of code. Identify the audience and the story and story board your app just as someone might sketch out scenes in an animated feature.

A pause...and then I saw him pop up on my screen, eyes warm and crinkling, smiling widely. “Ahhhhh, there you are!” he beamed, clearly thrilled to see me. It made me happy. He was right: it didn’t feel like a proper reunion until we saw each others' faces. ​ My internet friendships look a lot like my IRL friendships, but they lack corporeality, are impossible for me to get my fingers around. When we hang out in person, our offline interactions look a lot like our online ones: talking, analyzing, processing, thinking out loud, asking questions, reflecting, words, words, words. Our brains are directly wired into one another. Our bodily expressions are confined to heart-eyes, wow, angery, cry, or whichever limited faces our messaging apps allow us to make. We blow blue bubbles at each other. We convey our emotions through slang and punctuation, express our love through memes. ​ Robin talks about making a messaging app for his family, with a grand total of four users, and the joy of building things just for yourself, much like a home cook as opposed to a professional chef.

It is one thing for a proof to be correct; quite another, for a proof to be comprehensible.

Speaker: Tom Leinster (University of Glasgow) Title: An introduction to n-categories Event: Categories, Logic and Foundations of Physics IV (January 2009, Imperial College London) Abstract: I will give an beginners' introduction to n-categories. First I'll explain roughly what an n-category is, and talk about some of the dreams that first led people to want to develop a theory of n-categories. Then I'll go into more detail, leading up to a description of the state of the art and of some of the difficulties involved in trying to make those dreams come true. This is a completely introductory talk, for those who know nothing about n-categories. Experts will be bored senseless.

It’s easy but disorienting, and it makes the home into a very strange space. Until the 20th century, one had to leave the house for almost anything: to work, to eat or shop, to entertain yourself, to see other people. For decades, a family might have a single radio, then a few radios and a single television set. The possibilities available outside the home were far greater than those within its walls. But now, it’s not merely possible to do almost anything from home—it’s also the easiest option. Our forebears’ problem has been inverted: Now home is a prison of convenience that we need special help to escape.

To understand what it means to be self-compassionate, think about what it means to treat another person compassionately, and then turn that same orientation toward oneself. Viewing one’s problems through the lens of common humanity also lowers the sense of isolation people sometimes experience when they are suffering. It helps to remember that we’re all in this together. ​ Getting older brings undesired changes, many of which involve lapses or failures, as when people can’t remember things or have trouble performing everyday tasks. Even though they would treat their friends’ struggles with kindness and compassion, many older people become intolerant and angry, criticising themselves and bemoaning their inability to function as they once did. Others, meanwhile, seem to take ageing more in their stride, accepting their lapses, and treating themselves especially nicely when they have particularly bad days.

Try to ask one question at as many seminars as possible, either during the talk, or privately afterwards. The act of trying to formulating an interesting question (for you, not the speaker!) is a worthwhile exercise, and can focus the mind. ​ The reason for this phenomenon is that mathematics is so rich and infinite that it is impossible to learn it systematically, and if you wait to master one topic before moving on to the next, you'll never get anywhere.

If you truly love doing something, it’s always day one. There is no time or place you’ll ever feel you've arrived except in moments. What matters is not your ability, your talent, your achievements (or lack thereof), but that you keep on going and keep serving what you love.
