@jahnke One here. we are working lately on finite spaces.

@jahnke Yours seems really nice also! Though I must admit I am not really a partial differential equation guy...

I am a French PhD student located in the Paris area. That's my third year! (PhDs are shorter here than in some other places, so it might also be my last year...)

OMG, those little wheels will be deadly in any cracks in the pavement. Saw a lot of tourists renting them in Lisbon, and we had to keep an eye up and stay off their way on the sidewalks sometimes.

I almost wiped out on my fully loaded touring bike there, on a slick marble curb - right in front of the beautiful river Tejo.

Glad I didn't fall, it was heavy and the pavement was all granite.

@design_RG @freemo @jahnke I electric scoot... and for some reason especially attracted to holes and tall curbs, so had a few unpleasant falls... after my spinal surgery ._.

@freemo @jahnke Nice folding bike, specially in Stealth Black. I like it.

Into cycling myself too, although if I wanted to ride today/tonight, I would need a Fat Bike, we got about 15 cm of snow fall today.

I do bicycle touring as well, although it's been a while since the last trip. Love getting to new places.

@jahnke I used to bike a lot before my spinal surgery

#Biking in #Vienna

I usually enjoy #cycling in the #rain but today, in addition to a persistent precipitation, there was a blustery #wind #gusting up to about 70 km/h from the #south. There were a couple of moments on my ride home where I felt a little unsafe and unstable in the saddle at higher speeds. On a side note, I ought to add that #waterproof #overtrousers are an absolutely brilliant invention.

Hi writing.exchange, I'm Apple! I'm a writer trying to reach out to fellow writers, and am new to Mastodon. Anyone wanna show me the ropes of this instance? #introduction #writingcommunity

So I’ve heard about Mastodon, have no idea how it works but I’ll give it a go. Basically interested in most things scientific, particularly as they relate to climate change, the environment etc. That and general intelligent chat, if such a thing exists online. #introduction

@freemo @khird @jahnke I guess to make it less inflammatory or context dependent the message can be distilled down to "ambidexterity should be encouraged and rewarded (more)". I for one am often inconvenienced by finding myself with one tired/worn and another weak/fumbley hands, not even sure which one to consider "crippled" at that point... if not both.

@khird

Writing is a bit of a unique case. While it doesnt translate hand to hand it also isnt a x2 effort. LEarning a new script with one hand takes a fraction of the time to learn with the other hand if it already is capable of fine motor skills. But the movements are fairly different so there is some relearning.

In the case of handwriting by nature of the fact english is left-to-right writing I tend to recommend learning to use your right hand for that. Only time you'd need to learn the left hand is if you do a right to left script too.

Though its good to learn despite the usefulness due to just training your brain in general.
