It’s nice to know I’m not the only person who sometimes gets flustered while speaking
I didn’t realize infrared was discovered in the 1800s
hi from Indana just joined the r-15 club
Hello! Im from GA
Hello from Texas. This is my 3rd week doing power
Are we not just gonna talk bout that Humongous cellus bot!!
i Loved the part of infrared it was very cool!
Hey from Florida!!!
hey from GA
I think that the Aluminum Tube theing (Don’t Know what they would be called) Would be good to for making boats and buoys. (By the way Dr. John, I absolutely LOVE your new course!!!! )
Why can’t inferred light go through glass?
Hi everyone! Joining from Texas!
I really Dr. John’s part about The Hydro phobic metal and stuff like that. It’s pretty cool.
Hi from ohio!
Why is the Acellus dancing robot on the table?
I think the idea of being “socional” is really important because science doesn’t happen alone. It helps turn curiosity into progress.
We love and appreciate you both!!
Hello from small rural town in Illinois
Can we make an app called Socianal? Love y’all🌈

hi from TN
Hello from FL
Hi from LA. It is an honor to here at my first LIVE Science Live Dr. Roger Billings.

Make a noise and call it a word? That’s how you invent language.

HI from MT
Love the humor in every episode! Science live is interesting and engaging in every way!
hi from GA
Dr. John needs some love, because he is the best teacher
Hi, from Brasil.
I may not be a big fan of spiders, but the waterproof spider is on a whole other level of fascinating.
What I find fascinating about infrared cameras is that it can pick up the slightest thing with a fairly high temperature, such as gases being released into the air. I wonder if it could pick up gases like carbon monoxide, an odorless, toxic gas we can’t really see from the naked eye.
i loved the social emotion class it was great.
I want to get a prism and try out that experiment and see how hot all the colors are.
Hello im watching this from Alabama, and I would like to say that I love science live and it’s very inspirational!
Hi from Brazil
Amazing live

It’s interesting that infrared is a word Latin, although I realize now that there are a lot of science words that are Latin, so it isn’t that surprising that it is. Anyways, happy science live everyone!
