I like the don’t touch me plant, and the microcontroller.
GO ACELLUS WOOOO YOUR THE BEST!!!!!!
I do push-ups every day!
Learning about the aurdino was cool thanks to Dr.Tobias.
Hello from Florida
I can’t wait for the next Science Live!
I love learning new things every week. Happy anniversary…. Hello from South Carolina
The inventioneers were hilarious.
Great Science Live this week!
That is a very cool plant!!!! 🌱 🪴
Hydro power for the win!
The touch-me-not plant is so interesting! I’m excited to learn more about it as more and more research is completed!
Acellus is so easy to work with!🫶🏼
Didn’t expect to see Legos here today. Epic live ep lol.
Science Live is a good start to my day!!
I would love to see a hydrogen vehicle. We drive a Tesla, it’s awesome!
LETS GO ACELLUS!!!
Microcontrollers are really interesting!
I loved the proteges!
I love science live, it truly is the best.
Acellus is the best curriculum ever!!
hello from Alaska I loved todays episode it was the best and the proteges were great I loved learning about the Arduino and I think you should call the board the Acellus board or the science board or maybe the billings board.
Hello from Iowa!! Thanks for the awesome video!
Acellus is really good and I enjoy it.
Hello from Arkansas!🤗🤗🤗🤗
I am very curious to learn more about the new Pre Calculus course. I wonder how many units there are and what exact topics will be covered, is it for middle and high school students?
How come the plant closed when it was touched?
I enjoyed my first science live. I like the ideas they where suggesting. I hope these amazing since live videos can give me motivation to crate my on ideas. I hope Acellus will help me gain my right education, and help me follow my dreams.
This video was a fun one. I love marvel legos.
I’m excited for the new Acellus course! I love calculus. I thought it was interesting that a plant can close up when you touch it. I enjoyed hearing Tabias talk about Massimo Banzi.
My favorite part was the arduino part
I liked the Building Challenge!
Fascinated by tech
I Love Science Live!!!
Did the the proteges catch any fish?
I will be sad the day that I have to stop watching these. 🙁
The robot arm destroying the cupid castle was funny
The counting plant was very interesting.
i liked when they talked about the touch me not plant
I give a good luck to all from Georgia! Knowing about different science curriculums really gets the brain in gear and drives my curiosity!
I think it is a wonderful idea to add it to the acellus store, that would be what I would work hard for.
I love SCIENCE LIVE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I like the plant that closes when you touch it
Where even is Acellus world?!
Hi Dr. B, could you do a segment on how to actually code the Arduino? Is it block code or is it text based?
Acellus has changed my child’s life! Let’s get it!
The touch me not plant reminds me of how a venus fly trap reacts when an insect lands on it.
My pappy bought a small Arduino board just for fun and we made connections that were just with lights and buttons, and we have a new mechanical arm project to work on too.
I love the sound effects in Caleb and David’s bit.
I love r-51
i think that knowing that roller coasters need math to work is really cool
Is there any science behind plants growing better when you talk to them, or is this just a coincidence?
That was fun to watch! The one with the pigs was funny 😄
yay i love r-51
This was a good Science Live. R51 Rocks!!!!! Caleb and David always teach me so much, and they ALWAYS make me laugh. I ca’nt wait for next weeks Science Live. The best part about Acellus is Science Live.
Plants are so interesting!
yes, yes, yes!!!!! put the billings board on the acellus store!!
Acellus is fun
Hello from Alabama!!!
I really like the area 51 part!
I like the Arduino idea, but I do want to call it the billings board
I love Acellus!
THIS WAS SO COOL!!!!
those plants are crazy how they work.
I loved learning about the arduno
I enjoyed learning about Massimo Banzi.
Is the aviation course still a possibility
When is the new course coming out?
I love it when the Inventioneers are on! I need to do more research on the microcontroller.
How do roller coasters not fall off when they go upsidedown are their magnets under the track??
Hi I am from Round Rock, TX and science live is cool ! I always learn something new
I think the new math class will be fun and I think calculus will be fun
Science live is the best!!!!
I love Acellus
It’s so cool!! It’s cool that the microcontroller is used for multiple things, like controlling a washing machines temperature or controllimg drone monitors!
Hi ! From Gardnerville .
thank you for this platform🙏.
Has the 555 been used for light bulbs?
Thank you Acellus.
What are the positives and negatives to using a Microcontroller?
Can you use the bored to automatically make a bedroom door open by using sensors, or open you door from your bed by pulling a lever? I would really like to see that! And you should name the new bored your making “BBB” [ Better Billings Bored]
AYYYY GREAT VIDEO GUYS! I HOPE TO VISIT THE ACELLUS HEADQUARTERS ONE DAY 🤩
The prodigies have a mix of funny and educational and I love it!
Hi from texas, I enjoyed the live!
The science live was amazing this week!!!!
Girl power! So glad her house stood up the longest.
Another great episode of science live I love science so much
MEE LETS DO IT!!! Amazing video by the way!!
I love Acellus so much. It is so fun.
I LOVE watching these science lives every week!! I always look forward to Wednesday!!
I really do very much like and appreciate the amount of education in these episodes
Canadian bacon is awessomeeee
I thought that the touch me not plant was interesting.
i like the robot that picks up stuff
Hi from NJ thank you so much for doing these.
I loved watching the inventioneer towers.
hello from Montana ! -Luna R.
I learned about Calculus. There are 2 types of calculus: Integral and Differential. Differential Calculus is the study of change. Integral Calculus mainly deals with areas and volume.
Science Live Rules!
Entertaining as usual!
Haha maybe chat GPT is a woman. I love how arduimo has soooo many ways to turn the light on, multi-purposeful!
The funniest episode of the protoges ever.
This is always my favorite part of the day!!!
Writing from Texas!
Amazing episode will be coming back!
I’d love to see the hydrogen car at acellus head quarters!!!
Its really cool that a plant knows how to protect itself.
Billings Board!
I think this just proves Dr. Pajet is from a different planet where ChatGPT is the president 😂 How recently was the plant Dr. John talked about discovered and are there any other plants like it?
science live is always so nice to watch
Hello from Virginia!!
Science Live Rocks!!
Could an arduino be practical for any larger scale projects or is it best only used for smaller projects/tech demos?
Also I’d love to see you guys come out with your own microcontroller.
calculus sounds so cool, and I can’t wait to learn it!!
How cool is that “touch-me-not” plant!!! Never seen anything like it! And counting? Wow..
The plant looks shy.
I love R-51 he’s so funny(:
so cool dr. B
I really like these videos they are very helpful!
Hello from Illinois!
Microcontrollers are very cool.
Hydrogen cars are so cool!
i always like when R-51 does the explain but he does it in a funny way.
I love learning about computers and the way they work! So glad that Acellus embraces it. Love from Texas.
Hello from SC!!! I love science live videos!!
Hi from Utah I love every Wednesday look forward to science live every week.
Great episode. Liked The Protoges section!
I think it would be cool if you added the billings board to the gold credits store. It would be fun if you made it a kit that has instructions on how to use it and also had ideas for stuff to make with it that helps explain how to use it.
I love 💕 Tobias🤣
LOVE Acellus
Hi from Buffalo NY!
I enjoyed learning about the “touch me not” plant and its pulvini, and how it opens and closes to protect itself.
Acellus is the best!
I love Science Live. Every week has a new & exciting topic. I’m glad that Acellus Academy keeps introducing new courses. Calculus seems hard but I’m looking fofrward to taking it when it comes out.
Do you think chat gpt will ever get to 100 percent right?
Science live 🧪is so much fun
Happy anniversary. The concept of plants developing and even being able to adapt in a similar manner to animals is very interesting. I feel like the line between animal and plant is likely thinner than most think.
Can you please show this comment.
I thought this week’s episode was fantastic. My favorite part of the episode was the technology spotlight with Dr. John. Learning that plants can count was extremely interesting. I remember many science lives ago when Dr. John said that plants are actually able to talk in their own way, however, learning that they may be able to count as well is amazing. This experiment was a great idea since it not only showed how fast plants are able to adapt to their environment but also proved that it may have a functioning brain timer. The Science Live yesterday was amazing and I can ‘t wait to see what scientific shenanigans Mr. B and the Science Live will get into next week! (✿◠‿◠)
Hi and Happy 60th Anniversary for your hydrogen car! I like the Arduino:)
This would be a neat idea to invent something on our farm. Example cattle gates.
I wonder what’s there at Acellus world. I hope I can go this time, even if it is a bit of a drive.
The protégé’s and inventioneers were hilarious!
i love Dr.John
Can’t believe Dr John will be gone next week
I enjoyed hearing about the new Calculus class today!
I would love to see the 60th anniversary
Hello from Oklahoma, I LOVE SCIENCE LIVE!!!!!!!!!!!!!
The chat gpt fact is interesting. I have noticed that Chat GPT’s answers to questions change quite often.
I found it interesting how microcontrollers can be used in everyday technology. It really shows how important they are in modern engineering.
I love science love so much!
I did not know how microcontrollers worked.
R51 is getting smarter
I can’t wait to see all of the inventions for the science fair
It was really cool when they built a arm with arduino
The the inventioneers were cool I love lego
AWSOMEEEEEEEE😄😄😄😄😄😄😄
Yes, Arduino in the Acellus Store
This is the best part of Acellus.
I really like R51
i love mr. billings science
I thought that the touch me not plant was really cool because it could count and shut all of its leaves.
Happy anniversary for your hydrogen car!!! Also hello from Iowa. I just want to mention during the Protégés time, I totally have the Rubik’s cube like lamp. Although i guess it is more like a Tetris lamp.
Programming the light to go on and off was awesome
how dare you use a micro controller and not a samarai sword!
Where can i buy the tickle me plant?
How large can a microcontroller be?
Researchers at Washington State University did a study on ChatGPT where they asked it questions about science both true and false. It got around 80% of the questions correct. The researchers were also concerned that sometimes, when asked a question again, ChatGPT would sometimes give a different answer.
Hello from Texas!
R51 is the best. I enjoyed the video today.
sounds like a brilliant idea!!
they should put a microcontroller in the gold store
Are all electronics considered as computers?
That sucks, I love hearing from Dr. John, he is one of my favorite Science Live teachers. Those tickle me leaves look interesting. That’s crazy how those plants fold up all of their leaves after only one of their leaves are touched. Honestly in my opinion, these are the best houses for every lego figure. For Thor, you replicate Asgard, for Harry Potter, you replicate Hogwarts, for Cupid, you replicate Mount Olympus, for Lucy, you replicate Emmet’s Dream House from The Lego Movie 2, for Dr. Suess, you replicate the Goose Creek Tower, (and as a bonus), for Luigi, you replicate either the Gloomy Manor or The Last Resort from the Luigi’s Mansion series, for Batman, you replicate the Batcave, and for Alex, you replicate a house from Minecraft. R51 may not be the best teacher but he is definitely a good comedy show character.
Acellus is literally the best!
It’s really interesting how these simple organisms, like plants, have such complex structures and behaviors. Our world is very interesting!
