I REALLY enjoyed watching the protégés! I can’t chose between the 2 of them!!
I really need to set a reminder for all the space news, always disappointed to learn i’ve missed seeing a supermoon or something! Thanks Science live!
hi from Michigan!!!! I really love to watch old science live videos!!!! science is what we use every single day all day!!! 10 out of 10 I say!!!
I loved this episode!!!!!
How can you tell what is a comet compared to a shooting star? What differences do they have or are they the same thing?
What else do people need to know about integrated circuits
Thank you for taking the time to make this video, it’s always fun learning something new.
I loved learning about comets
Watching from Ohio
I did not know circuits worked this way!!woow!!
I enjoyed learning about the comets in this episode. Space is so interesting!
The comets!!!
Traveling 190 feet in one second is incredible. From 6 hours ro 2 1/2 hour.. so cool!. Great video!
I love these videos! They teach me so much.
This was a fun one, funny how his assistant got shrunk😂
6 or 7 days…? I love the proteges, they’re so funny xD

Integrated circuits are tiny chips that help computers work. so cool and fun to learn.
What are the three main tiny electronic parts found inside a circuit chip?
I enjoy R-51’s experiments because it’s a lot better to comprehend sometimes.
Why were integrated circuits so important in reducing the size of computers?
I think the comment should be called the dream comment ☄️
AGREED!
Do you still have all the elements on the periodic table memorised?
All those tubes you had to watch like you having to babysit them so if something happen you could fix it.

There is a comet brighter than the sun
So cool how fast the bullet train goes. Really enjoy watching and learning from the science live videos
I also loved seeing Dr.Billings.
I learned about the bullet train in my geography class. One day I would like to ride on it.
The live video was very interesting. I love the part where the 5 contestants made a integrated circuit and the last one won. I was very nice meeting Dr.B
If you look at the original pictures, the reason why they changed the design was because the people who lived by the tunnels that were built complained about the noise the trains would make when they came out of the tunnels so they changed the nose design in order to prevent that.
You are one of my biggest insparations Dr John!
Comets are cool
The comet part was really interesting.
The integrated circuits were fun to learn about.
this is great! i look forward to watching these
