300th episode! I love Science Live!
Favorite show!
3D printers are awesome.
It’s incredible how much computers have evolved throughout such a short period of time!
My great uncle used to tell my grandparents that one day everyone would have a computer in their home. They said that would never be possible. Now today we all carry them in our pockets!
I love science live!
The jellyfish galaxy picture was really cool. I think photos like that are beautiful
Crazy how far tech has come to be able to construct 3D objects!
I enjoy every episode!!!
I like science live
I love science live!!
I’m so glad computers were invented!
