The Biggest Ideas in the Universe | 2. Change

The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #2, "Change." Which is a less-threatening way of saying "Calculus," which is the mathematics of continuous change.

Great. Carroll is entering his Feynman lectures stage of his career where he helps us all understand what is going on, but during his lunch break. Thanks Sean.

"figure-outable" is definitely my word of the day :) Thanks for the light-heartedness of conveying these ideas

[@smith5796]

The sound of Sean Carroll's writing and the way it appears on the screen is really nice.

[@BladeRunner-td8be]

Sean is a great communicator. The tenor and pace at which he speaks combined with the simplicity, enthusiasm and energy he puts forth are about as good as I've seen. And that cat is pretty darn big and definitely well cared for.

[@thoel1]

Sean Carroll is honoring us by coming down to the basics, in order to clarify us the implementations of abstracted (thought to be) mathematics in research of the Newtonian properties of nature. Until now such lessons were either too advanced to clearly understand, or too flat in the shake of public simplification. He manages to bridge these aspects and this is great! Thank you Sean!

[@deansundquist9601]

Titling this ‘Change’ is a smart move by a brilliant professor to drop the c word two minutes in. Loving the videos!

[@randytighe7150]

Hi Sean, Love that you're sharing your knowledge with those of us who are fascinated with physics but may not have the depth of mathematical knowledge required for the full mathematical treatment of the subject. At the same time you're giving us a glimpse of the math and inspiring us to delve further. You seem to truly respect your audience here. Thanks for doing this.

[@ralphhebgen7067]

One thing that has always impressed me about Sean is his eloquence. I do not think he reads off a teleprompt, and yet his language is lucid, eloquent, rich in vocabulary, nuanced, and fluent. His statements are not interrupted by interjections like “erm”, he does not even use qualifiers like “sort of”, and his videos appear to be entirely unedited. Also his presentations appear entirely natural, they are not polished in a way a public speaker might deliberately design an address to be impactful. The result is a lecture that is easy to follow, and the listener can use all of their attention to focus on the topic Sean is discussing. Top marks from me! I love this series.

[@TXDomer]

I hope I'm not the only one, but I really look forward to these video releases given the situation going on around me. Thank you so much Sean for sharing your knowledge, especially during this time. Keep up the great work!!!

[@willnzsurf]

What'd you do during lockdown? Learn Calculus!

It is pure enjoyment to be allowed in to your home and be educated in such a pleasant way. And the cat is just adorable.

[@shaun906]

sean is so good at explaining this stuff! Considering how advanced his work and teaching is sean takes the same time and effort for all levels of learning. big fan

[@seancarroll]

Questions [based on the video] left here over the next day or two will have a chance of being addressed in an upcoming Q&A video!

[@anmolmehrotra923]

@SeanCarroll is there an absolute time? Like if we say that speed of light is an absolute speed, can we talk about absolute time. Or is there no absolute time as everything is relative to one another and 'think's' that their time is absolute? #Q&A #QandA

[@SuperemeRed]

@SeanCarroll As a graphics artist loving your stuff, the white background is a bit tiresome to look at, especially as the rest of your video is primarily dark-ish. Does the app you are drawing in have to possibility to set a color close to dark chalk board with white chalk for text? It would be easier on they eyes and thematically fit well :) I made a mockup, something like this: imgur.com/WMLhxci

[@derekallen4568]

People give Pascal a bad rap for coming up with Pascals wager. Pascal said pressure on a liquid is equal in all directions, no matter where it is measured. Force is pressure x area. He is the father of modern hydraulics.

“You can run for President with the motto, ‘change’ but no one is gonna run for President with the motto, ‘calculus’. LOL superb.

[@MissEviscerator]

I am so grateful that you have taken the time to make these videos (and so many others). You really have changed my life and made physics accessible to me in a way that no one else has. My apparent inability to comprehend the physical world has always haunted me and I can't put into words how good it feels to finally overcome that! This affects me not only on a personal level but a professional one too: I am researching molecular pathology, and learning physical theory helps me to think in a far more logical manner than I did before! Thank you so much - you're an incredible teacher.

[@squatchymcsquatchsquatch3015]

I love your use of the term, "figure-outtable." Definitely why you're one of my faves

I think one of my favorite things about your lectures are how you can insert your (very dry) humor without it distracting from the material. Really appreciate you doing these lectures!

[@biancapiccoli5588]

Just listening to these lectures walking to my physics class is giving me so much vibes and confidence that I don't know what I'll do when this series will end (sorry for my poor grammar, haven't checked it)

[@Epoch11]

Sad when you learn in one hour what a bad teacher can't get across in an entire YEAR! Damn Corona Virus had to happen 20 years too late!

[@tomsemo8186]

Absolutely brilliant.. With my teenagers home, mandatory video. And thay love it. much discussion after. Good stuff.

[@kccust]

Carroll's enthusiasm for science is contagious. We are so fortunate to have brilliant people like Sean to inspire.

[@Bronett]

For me, not to get a nervous twitch from the word "calculus" and numb off, is already something - but actually getting a sense of what is (might be) going on, is an absolute pleasure - Thank you so much!

[@waynearrington6727]

The best science communicator and educator I have ever encountered. Really appreciate the flow of words and ideas; the absence of ahhhh, you know and all the other fillers that people use when public speaking.

Such a brilliant description of the concepts behind calculus! I also love the dichotomy of an amazing science educator and physicist showing off their cat and apologizing if they destroy the green screen in the middle of the lecture.

18:50 "here's my version of a car... " , still better than Cyber-Truck

A more heuristic understanding of integral: The odometer is the integral sum of all the speeds. Changing fast at high speed and not at all when stopped. A mathematician will not pick up a hitchhiker because he doesn't want to integrate their weight over distance in fuel.

[@vikranttyagiRN]

Sean Carroll and Brian Greene, two of the greatest physicists of today's times circulating knowledge in these times is hugely applausible

[@timothykeech7394]

I have watched many videos on Physics by eminent scientists and they are fascinating. (I used to teach the subject in High School) but Sean has such an engaging and fluent style of delivery. He is an extraordinarily good communicator and probably doesn't even realise it himself. Thank you Sean for sharing your knowledge and enthusiasm in such an entertaining way.

[@canopus127]

Thank you Sean! You are one of the coolest professors I have ever seen. You explain the stuffs of physics very innocently. Thank you again!

[@vcothur7]

We all got bamboozled into taking a calculas class. Not that I'm complaining.

[@amrabdellatif9956]

[@bobpalka2085]

Would hate to admit the percentage of this lecture I understood, BUT what little I could comprehend was a step up in my education. So much more to learn so little time.

[@miguelrodriguez-ht3ct]

great simple explanation, problably if I'd been taught this way calculus, I would have not suffer so much

[@Artie_D]

Thank you Sean, you are doing a fantastic public service. Lots of people’s are trapped, have plenty time on their hands and unfortunately in many cases lots of doomed & gloomed thoughts in their heads. These lectures help people to distract themselves from those thoughts and learn something they might never had a chance to learn in regular, mundane life. THANK YOU.

[@NalitaQubit]

Thank you Sean for this series. I love your lectures. I haven't touched a physics textbook in 30 years but this is absolutely mesmerizing to me.

[@TheHogan883]

I love these videos. Thank you for making them.

[@badron8846]

I guess the main problem in making physics describe how a river flows or how wind blows, is that their are simply mind boggling amount of particles involved and doing the math on that many objects is basically impossible.

[@mef9327]

[@PaulinaFriedman1974]

Thank you for reminding me why I fell in love with Physics!!! BTW, our Mathematical Analysis professor told us that before he understood Integration, he'd done over 500 integrals, using all the methods he shared with us. I wasn't as bright, it must have been at least a thousand examples. Good times :)

[@radical137]

My new favorite physics teacher, I will watch the whole series playlist. He says he is not going to get into much detail, but he ends up teaching you a metric ton of interesting detail. You should watch in order if you have the time because he refers to previous lectures often.

[@arnoldleaf4521]

Great stuff , thanks Professor . Between u, Professor Green n all the other great scientists producing these great videos , it really helps make this tragedy a little less traumatic. Understanding the world at this time is confusing to say the least ! N getting a chance to learn from such high level teachers on a regular basis really takes the edge off !

[@yellibell6325]

Thanks for these great videos - and thanks for making them free on TouTube! I am enjoying indulging my childhood fantasy of becoming an astrophysicist. During this time of stress and change it is wonderful to take the perspective of the universe for a little while and to take my mind off of the uncertainty by challenging my brain to learn new things.

[@simatbirch]

This is so great.

[@sztaba100]

When I studied calculus I also wondered why integration was so much more difficult than derivation and the answer that I got satisfied me then and still does. When one is working from observation or data points that are plotted on a graph the function is very often not known. In other words we are looking for a formula that might not yet exist and hence the difficulty. Sorry if I've repeated something somebody else has already said.

[@imacds]

Why would that make integration harder than differentiation? Don't you need the function to both integrate and differentiate?

[@gildastigliano7936]

Thanks for doing these Sean. I have an engineering background so I learned a lot of this stuff in my undergrad, but I really enjoy hearing your commentary as you're building up the basics. I'm not sure if you ever do interviews with KZbinrs, but there's an atheist KZbinr I enjoy named TJump who does philosophical debates with theists. he references your work on emergent spacetime models and he definitely shares a lot of your views. I would love to hear the two of you chat if you ever get the opportunity. thanks again!
