I love sign language so much. I have learned so many cool things. And that is amazing that a 15 year old girl wrote such an amazing book
It always amazes me by how people are so talented and creative and have the ability to create amazing inventions from ideas that they believe is impossible at first.
I’m definitely gonna try the new sign language class!

Wow! I didn’t know there was another telescope being launched!
I’m interested in the new ASL class. I loved the last one.
It was so much fun learning about Edison and the vacuum tube. I also appreciated the clarification that he did not invent the light bulb, but made it better and more affordable.

Thomas Edison Mentored Roger Billings Mentor?!?! That’s Crazy!
While the touch screen keyboard is pretty great I wonder if we could make it a little more accessable? My grandpa has large hands and fingers and has a hard time typing on a tiny little screen keyboard. The new telescope sounds amazing, covering that much sky taking pictures is going to be revolutionary. I’m very glad to be on winter break, but I’ll miss science live till it comes back!
My favorite parts of Science LIVE is R-51 and Technology. Great live! Happy Holidays!
