I never realized that older digital keyboards try to improve typing sensitivities based on predictions! Maybe I could test that with modern devices.
I did not know Thomas Edison created the vacuum. He must have invented a lot of things.

I am most definitely taking ASL as of course because that’s just so fascinating to me and I’ve always wanted to learn sign language and I just feel like that’s very important to learn and that’s something that every child should be learning because that’s actually considered a life skill because you never know who you’re going to come across.
How does heating and cooling elements work? I didn’t know that Thomas Edison created the vacuum! That was so cool!
Learning about Thomas Edison is such an interesting thing to do, I learn something new every time!
