Itโ€™s very tedious having to mute all the accounts posting over saturated photos.
Pretty much this:

My handwriting is getting worse. How difficult is using a Shavian keyboard layout?

Really enjoyed this, and working through Beggsโ€™ book now.

Perhaps dynamical systems theory, and/or the critical point hypothesis, etc.will help at least better define the shadows.

Some time ago during my research I had the thought that all the measures we have of brain activity, and the research we do, are based on shadows cast upon the walls by the systems that are really of interest.
I think this is why, e.g. using EEG to detect seizure activity is so challenging. 1/n

I discovered the Shavian alphabet today. Fascinating.
Thanks @shavian.info for all the info on your website!

Enjoying the show; havenโ€™t read the books. I agree the episodes are a bit short, IIRC, 28 minutes including the intro and recap.
I would like to watch Sanctuary Moon. Maybe theyโ€™ll do a spin-off.

โ€œโ€ฆ I want to say in my defense that I often ask questions where I think I know the answer, as a way of checking my understanding without leading too strongly.โ€

I do this /all/ the time.
Definitions and foundations are /so/ important. That coupled with our brainsโ€™ tendency to โ€œfill in the gapsโ€ 1/n

There is beauty and control in your graceful movements that are nicely juxtaposed with the powerful woman in the picture behind you.
I feel that pic could be a large backdrop for your performance. โ€œWhile I rage, I am in control.โ€
Not trying to put words in your mouth, just really moving to me.

Is there any comprehensible explanation about how time is affected?
I know โ€œspacetimeโ€; one and the same. Maybe I just donโ€™t have the background to understand.
