Today’s lesson was interesting, thank you Dr. Billings!
Happy Holidays!
I love that were gonna get a new telescope that takes better pictures and has better view!
Happy holidays everyone from Owen in Reno!
Edison’s perseverance was impressive.
That was so cool! And the ending was funny haha!
Today live what neat to learn about apples keyboard and how they were able to fix the issue and find a solution. I really liked learning about the Edison Effect and about the filament in the bulb temperature being 2,700 degrees Fahrenheit. Also the vacuum diode which was a one way flow of electrons in a vacuum. Merry CHRISTMAS to everyone.
Steve Jobs was really ahead of his time.
My second comment tonight:)
How awesome that not only do you help us with tuition when we watch these awesome episodes, but next year we will be receiving Science credits!!!! Yay!! So cool:) Thank you!!
I enjoyed learning the history behind the first iPhone. Also enjoyed the photos from the Hubble telescope. R-51 cracks me up.
R-51 is so funny
I love looking at the pictures from the hubble telescope online, I can wait to see the new images and videos this new one produces!
I love learning through Science Live!
I thought it was awesome that you talked about Washington State University (Go Cougs!) because my sister graduated from there and I have been there many times!!!
Happy holidays! and love all the info!
So excited about the ASL course!!! Thank you:) Happy Holidays to all:)
Thank you for this opportunity and everyone stay safe and have a wonderful holiday.
I love hearing about space telescopes and how we are continually advancing to get better and clearer images. Merry Christmas.
I’m so happy that they made ASL 2❤️.
What made you so interested in hydrogen?
I’m very excited for the new class.
Science live is amazing. I love learning from all of you.

oh chemistry, oh chemistry! thank you Dr. bilings.
Happy Holidays from Texas!
Hello from Washington
thanks Dr billings
happy holidays everyone!
Wow! I’m so excited for the new ASL class. I’m currently in the first ASL course.
What are the operational costs of the new telescope?
Dr. Tobias is talking about how the first iPhone was made but, how big was the first iPhone?
Happy holidays, Acellus family! My family and I love watching Science Live. I am hoping they will post the pictures with the telescope; this is so exciting. I was really intrigued by The Edison Effect. Thank you for sharing with us!
What are some other uses for Hydrogen?
I’m happy about the new ASL course. Happy holidays!
The Edison Effect sounds amazing! Are there more inventions that Thomas Edison made that he isn’t as well known for?
It’s hilarious that R51 called Thomas Edison from the past and told him he was his student abut Edison completely denied it.
The Morse code was amazing and the 8 ft Nancy Grace Roman telescope was interesting! I learned a lot from this video.
I loved learning about phones. And r51 is always one of my favorite parts.
Its always interesting to learn about the origins of cell phone technology and development.
My family and I like to look at images from the Hubble telescope. I hope they post images from this new and improved telescope.
Love seeing R-51, happy holidays.
It so cool that there is a new sign language course! looking forward to taking that course!
It was a breakthrough when Dr. Roger Billings started Acellus.
Now I know that NASA is creating a new telescope using different technology to search for new planets.
I’m currently doing ASL, just started it a few weeks ago and I’m doing pretty well. I just want to say… R51, even if no one else likes you, I do lol. And Merry Christmas everyone!!
Science live is fun. And there’s always a lot of cool facts.
Hope everyone has a happy holidays!
I really like it and my kitty likes it too. He was snuggling with me. I really like it. You did a really good job.
Happy holidays from El Paso
I’m so excited for the new ASL class with Ms. Donnie, it’s so funny because earlier this week I was thinking how I really wish I could just finish up connecting all of my vocabulary so that I can be more fluent! Very excited for a new year of science live I have been working so hard in my studies recently and it’s really been paying off! I got almost perfect scores in 2 of my midterms, and did good in last year’s state testing. Thank you Acellus for all you do if science live hadn’t of been created I wouldn’t get to do a lot of the things I enjoy doing because of the flexibility. Merry Christmas, and Happy new years Acellus team!!
Very cool learning more about Thomas Edison’s inventions and how you are connected to him.
You are very smart R *
Happy holidays and New Year everyone!!!
The new ASL course looks so fun! My mom took ASL in Highschool as her foreign language!
Amazing! I loved the story Tobias told, the way he told it made me want to listen more.
Thomas Edison is so cool! It was so interesting to learn about all of the things that he did. I’m so glad he never gave up!
Thank you Dr Billings for caring about all of us students.
I love watching theese videos every week!
ASL is so awesome! I finished it and now I can talk to deaf people! One of my moms friend has a deaf kid, and now we’re friends because we can talk to each other!
R-51 is the coolest! Happy holidays to everyone!
I love Acellus live!
Happy holidays to everyone!
As always I never get enough of these lives they are very interesting to watch
My twelve year old sister is currently taking ASL classes!
I love watching this video on Edison’s discovery with my mom
I loved learning that Thomas Edison created the first affordable lightbulb.
The first touch screens needed a stylus pen and used pressure to select the letters being typed.
It was interesting learning about the vacuum tube.
I am so excited for the new ASL course!
I never knew that about the keyboard on the iphone!
A new telescope is so exciting!
Happy Holidays!
R51 is funny
Where does the interference in space for the telescope actually come from?
now I will not be able to get this song out of my head
The one way flow of electrons is very interesting.
Area51 thinks he can go back in time and so funny because he thinks he was Thomas Edison’s favorite student and he didn’t even know him. 😂
I like Morse code and big telescope! This is very cool video.
Thomas Edison is really smart and fun to learn about! Merry Christmas everyone!
I am so excited for an ASL class, happy holidays.
This Science Live this week was pretty interesting. Congratulations to Lorelei Fox on publishing a book at such a young age; that is truly amazing! I can’t wait to see what Science Live bring in 2026. Happy Holidays to you all!
I can’t wait to take ASL 2!
Happy Holidays! The making of phones is so interesting!
Happy holidays everyone! I love watching these science lives
Do LED lightbulbs use the same technology as Thomas Edison’s lightbulb did?
How did Thomas Edison create a vacuum in the light bulb?
Thank you for the new knowledge!
Love these videos!! And happy holidays.
Happy Holidays I love Science live
R-51 always cracks me up! Happy holidays!
r-51 is so cool! and happy holidays to those who celebrate!!
I didn’t even know that there were little areas of sensitivity on phone keyboards. It really shows that you can take a “failed” idea and make it into something even better than a new idea!
Happy Holidays, I love science live! Thank you Dr. Billings.
Happy Holiday’s to the Science Live team!!
love R-51. Happy Holidays !
How did Edison manage to stay motivated through all his failed experiments?
Learning about how they made the iphone we know today was really fascinating! can’t wait for the new year of science live!!
Happy holiday to all science live!!! So fun to learn about things!
While trying to create different inventions, how is one supposed to focus on each individual one?
We are grateful for “Project Purple” from Apple!
I am so excited for ASL II !!! Thank you.
That telescope that NASA is gonna launch sounds pretty cool! Too bad we have to wait till next year…
Happy Holidays to the teachers, the students, everyone!
Happy Holidays I love watching science live.
I love this “oh chemistry, oh chemistry.” is iconic and the Area 51! Merry Christmas everyone.
The history of the iphone keyboard was interesting, I didn’t know that.
My mom always likes to use Thomas Edison as an example of how to persevere when things don’t go right the first time.
I never knew chemists had their own holiday song. Wonder what biologists sing. Maybe, Oh Biology, Oh biology… Looking forward to this Science live!
Roger billings is the GOAT
Amazing to see how far the lightbulb has gone, from being small and inefficient to being so common that we color them and put them in our Christmas trees. Merry Christmas everyone!!
Really enjoyed this episode
Happy Holiday everyone! Can’t wait to see you all in 2026.
I’m excited about the new ASL, but will there be a Spanish 3 as well?
I love Science live! I can’t wait to watch this episode
I believe Thomas Edison knows you, R 51
