Hi @freemo, how are you? Kids already do write with their both hands. That's how keyboards work. :D

Now, being serious, why do you think people should double the efforts to learn to write with their both hands? They already learn many ways to write and to record information: handwriting; keyboard writing; writing using their phones, recording their voices and even video.

My opinion is that their time should be used in a better way, like how to express their thoughts (writing and speaking), how to construct arguments (traditional academic and modern "feeling based" arguments), or just playing around with other kids. :D

Today I am grateful because I learned that "a semisimple Lie subgroup of a simply connected Lie group is always closed [1] pg 615" and I needed it for my research. :D

HI @manav, how are you today?

It's hard to recommend a book without knowing what you need it for. What do you want to do with trigonometry? :D

Wellcome, @manav. =)

Dear @Zyzzyva,

In my opinion, the best book by Vinge is "A Fire Upon the Deep." But it is not short. It is worth reading anyway. On the other hand, Lovecraft has many short stories. You can read most of them online in one short sitting. One of my favorites is "The Cats of Ulthar": http://www.hplovecraft.com/writings/texts/fiction/cu.aspx

About language learning. You can go a long way of studying it passively. Just get some TV shows you are used to watching in English and rewatch it in German. I did it with friends many years ago. First, I watched it in Brazilian Portuguese, then I rewatched it with audio and subtitles in English. This is a great way to learn a lot of vocabulary. Be warned that this ability does not transfer very well to writing or speaking.

@arteteco Anything by Heitor Villa-Lobos is worth listening to, but start here: https://www.youtube.com/watch?v=XUrugDn2g6s

Are there other mathematicians around here? Please, show yourselves! And tell me about what you are working on. :D #math #maths #mathematics

Hi, my name is Max Reinhold Jahnke. I'm 34, and I'm a mathematician from São Carlos, Brazil. The main reason I'm here is to write about my hobbies and connect with new people. I love #mathematics, #reading, #writing, #learning foreign #languages, watching TV shows, and playing video games.

I'm a post-doctoral researcher at the Federal University of São Carlos, and my research field is Partial Differential Equations. I will stop here because I don't want to scare anyone.

I usually read science, fiction, and fantasy. My favorite authors are H.P. Lovecraft, G.R.R. Martin, and V.S. Vinge. Now I'm reading the series The Expansion, and I'm loving it.

As I said, I like to learn foreign languages. Some years ago, I studied a little #Esperanto, but I didn't reach a high level. I can read the Esperanto Wikipedia and some news in Esperanto, but can't speak the language.

I'm always learning. Usually, it is mathematics and languages, but I also like to learn about other cultures, science, and technology. Most recently, I began learning how to bake bread, my main interest is in #baking #sourdough.

@design_RG hi Rob. I just discovered Mastodon. I'm not familiar with it yet. Thank you for sending me this guide.

Hi. I am a mathematician from Brazil. How are you guys?
