where can I get the book?
Who or what inspired Thomas Edison?
Thanks for making these every week! They are really informative.
How is the new NASA telescope able to take pictures of such a wide area?
There should be a showing for the new telescope where the people can watch it launch.
Dr. Billings, it’s amazing how inventions that supposedly had no promise ended up being something we use a lot today.
i love r-51! cant wait for christmas and wish you a happy new year!
The solution for the iPhone keyboard was very interesting, I never would’ve come up with making the boxes bigger based on what it thinks you’re typing.
Dr. Tobias, why did they name it Project Purple? Was the name symbolic in any way?
I was just asking my mom who invented the light bulb!
Dr. John, with the new telescope, will they be able to see heat and measure temperatures on other planets?
Thomas Edison was one smart guy!
science live is the greatest
I am wondering how people invented the floppy disk!
I really thought Edison invented the light bulb.
Dr. Billings, R51…if anything, you were mentored by Dr. Billings!
Dr. Tobias, who did Steve do the demo for? Was it the public or other business people?
Dr. John, will scientists be able to tell water from land on the exoplanets with the new telescope?
The new telescope’s new resolution is going to be able to capture more things to study.
Amazing Science Live, happy holidays!
I love r. 51!

I never realized that Thomas Edison did not invent the lightbulb but instead he was the first to make a practical one.
Cell phones looked weird . I’m glad the engineer figured out the keyboard and we have iPhones and iPads now.

The chemistry joke was funny. I learned that Thomas Edison didn’t create the lightbulb but he was apparently the first to make one that was practical and affordable.
I really enjoyed this video! Science live is the best!!
Really enjoyed this breakdown of the Edison Effect it’s fascinating to see how Edison’s observation of electron emission from a heated filament laid the groundwork for vacuum tubes and modern electronics. It’s a great reminder that even small, curious experiments can lead to huge technological leaps
Hi i love acellus and science live im 8 you are so pretty pajet monet
I like that Christmas song “O Chemistry, O Chemistry. Oh how I adore thee. Lol
Edison is the most impressive inventor ever.
