To try everything Brilliant has to offer-free-for a full 30 days, visit brilliant.org/FoolishChemist. You’ll also get 20% off an annual premium subscription. In this video, we "derive" (or rather, intuitively explain) the formula for line integrals over vector fields and describe how to evaluate them with some examples. Then, we use that knowledge to build up to the fundamental theorem of line ...

What Does the First Law of Thermodynamics Really Say? | ChemWalks-001
Просмотров 5453 месяца назад
ChemWalks-001: A detailed description of the formula associated with the first law of thermodynamics-dU = q - w. This video spends time discussing what internal energy (U), change in internal energy (dU), heat (q), and work (w) really mean for a system, and how they all fit into this equation. Nuance with writing q - w vs q w is also touched on. ChemWalks is a new video series I'm starting wher...
Introduction | ChemWalks-000
Просмотров 1423 месяца назад
ChemWalks: a new video series I'm starting where I candidly explain concepts in chemistry, math, and physics in on-the-go. The goal of this series is to focus on sharing intuition rather that getting too deep into the details, and just see the big picture. In the real world, having intuition for concepts can often be more valuable than remembering a formula or a procedure. By making these video...

All of Multivariable Calculus in One Formula
Просмотров 148 тыс.Год назад
In this video, I describe how all of the different theorems of multivariable calculus (the Fundamental Theorem of Line Integrals, Green's Theorem, Stokes' Theorem, and the Divergence Theorem, plus also the original Fundamental Theorem of Calculus in one dimension) are actually the same thing in higher math. I present this by going through each theorem conceptually step by step (no formal proofs...

In this video, I use a crystal making kit which I won from Dave and Busters to make a green glow-in-the-dark crystal. The chemical I used to make the crystals was ammonium phosphate. The basic process, if you would like to try it at home, is as follows: 1. Heat up some water (greater than 70 degrees Celsius) 2. Dissolve a lot of ammonium phosphate completely in the water 3. Allow the water to c...

Gabriel's Horn - Breakthrough Junior Challenge 2022
This is crazy stuff...... Blown up my mind
I worked for a bank where savings account interest was compounded continuously. I used both Euler’s Number e and natural log ln quite frequently. Your explanation made sense to me. Next time you are talking to a banker ask for a proof of how your savings interest (Annual Percentage Yield) was determined. I bet no one in the bank can do the calculation let alone explain it.
Too much complicated
Fail.
The fact, that the language of the Math is not comprehensive to me, makes me sad.
scalability of large numbers by a factor, decimal converter? Used highly in diff eq, the visual helps, thanks, now how to upscale control theory into life?
Up until your discovery of constant-variable lambda I felt I was with you. From that point on I would need much more graduation. Very unfortunately I lost you from that point on. David Lixenberg
Tipical american: all about money.
Isn't dr/ds the unit tangent vector, whilst dr/dt the actual tangent vector ?
Hot Tip: (1.0000000001)^⁹ = e This is the smallest number taken to the exponent of its decimal place which is e, or 2.718.... Just add more zeros between the ones and take it to a higher exponent to get "e" with more decimal places.

Great video explaining e. I never thought e can be describe as "the self referential growth or decay" of itself. Nice!!!
Trancedental number like pi and square root of not perfect square
I'm sorry, but to ignore calculus in a video trying to give an intuition for e is a somewhat baffling move, since what makes e significant is its use in calculus (specifically for taking the derivative or anti-derivative of an exponential). Walking through how solving f'(x) = f(x) naturally leads to an exponential, and further showing that the base of that exponential is an exact constant, also gives an intuition on why it matters in chemistry and physics, after perhaps explaining why exponential equations are used to model how certain kinds of systems evolve (and how the past of them can be predicted) based only on some constants of the system and the current state.
This video is incredible. Keep up the good work!
Thanks for making this video sir, really helpful
very helpful!
No fire:(
I really wish the rest of this playkist was out my midterm is on Wednesday and this is so much more helpful AND ENTERTAINING than the explanations I've seen so far. SO MANY PEOPLE MAKE MATH BORING, you do not, thank you
This is extremely good
I think the basic line integral is a weighted sum of infinitesimal vectors. The result is again a vector. Taking the length of ds complicates matters, and generates a big discrepancy with line integrals in the complex analysis.

1:06 nor is pi. Pi is irrational and cant be expressed as a ratio of two numbers.
Of two integers, no…but there’s no guarantee that the circumference and diameter of a circle will both be integers (therefore it is still a ratio of two numbers). In fact, pi being irrational tells us that that’s impossible!
@FoolishChemist so it can be expressed as a ratio of two irrational numbers?
@@michaelcolbourn6719 Doesn't even have to be two irrational numbers. In fact most of the time it's one irrational and one rational. It just can't be two integers!
Pi is the ratio of Circumference:diameter We aint talking about numbers here.
Yet another rehashed bad way to teach e. Not knocking Foolish Chemist. It’s a good math video. We tend to teach math by backing into concepts from an historical perspective. Instead we should relegate the arduous path to discovery of things like e and i to a math history class. Now that we have a better understanding of these concepts we should start with a modern perspective.
E is a letter that represents a number of
So Euler's number is the same as natural log. 2.718281828459 ?
A natural logarithm is a logarithm with base e, so ln e = 1.
This is exactly how my tutor explained e
wtf is h
Plancks constant!
You seem to have accidentally given one of the great argument for why τ (the ratio of a circle's circumference to its radius) is more practical than π (τ/2), right at 18:31 !
Ahhh, a good point! I didn’t even think about this lol
😞 Someday, I'd be smart enough to understand this.
If you don't understand, then it's not taught right for you.
Here is e in one sentence: The only value where the derivative of a^x = a^x
a=0
@@fullfungo except 0
@@fullfungo You need for a^x to be defined for all x, and since 0^0 is undefined (I know taking the limit implies it should be 1, but that still requires a limit) you can immediately rule out 0 as a possible value for a.

Good video on euler's number
Hi, can you please provide link for website you used to generate the vector fields
How long mixture last, can you make the mixture and store it for future use will it still be effective.?
Nicely explained though It was difficult to understand why you were applying the lambda exponentials.
The most popular definitions for e: The one in this video: e = lim(n to inf) of (1 + 1/n)^n The infinite sum of 1/n! starting at 0 (n! = 1*2*3*4*.....*n) e is base for the natural logarithm e is the base for the exponential function exp(x) where the derivative of that function is also exp(x) so f(x) = f'(x)
or the solution to the ivp y'=y, y(0)=1
you can also change that limit to the form e=lim u->1 of u^(1/u-1), which is a lot easier to compute
The reason we choose 100%(100% = 100/100 = 1) is because 1 is the multiplicative identity over the real numbers(and all of the numbers you will ever use)
doodoo kaka
@Yunahsky wtb modular arithmetic, for example 6 is a multiplicative identity mod 5
@paridhaxholli 6 = 1 mod 5.
"It's the constant of self-similar change" is my best pre-video attempt at distilling e in one sentence.
had this exact thought as well
just a clown
