Lol.😂
Reality really tries to bring you back down. Where are my beyond-advanced-calculus peeps at??🤣💜
📐The Calculus of Falling Bodies
How can math explain motion under gravity?
This week's newsletter explores velocity, displacement, quadratic equations, and the domain of a falling body's height function.

Old friends are the best friends. Jensen rocks.
The Star Mind computer being co-engineered by SpaceX and Nvidia is far better than almost anyone expects and will reach volume production next year.
Working with the incredibly talented Nvidia engineering team is pure joy!
Jensen Huang says he loves working with Elon Musk, and reveals their engineering teams are designing a new type of server to put data centers in space
“I’m delighted that I love working with Elon. He’s using our technology for his own AI in training models and such, deploying models, of course."
"Grok Bot is super cool. The demand for Grok Bot, the consumption for Grok Bot is really skyrocketing. And then, of course, he rents it."
"And so the combination of these three things, he’s fairly unique in doing that. I guess Google does that. That would be yet another example."
"And so I think he also has the advantage that he loves the intersection between computing and the physical buildouts. He loves that whole area. Nobody knows more about energy than he does."
"One particular new market that we’re going to go explore together is putting data centers out in space. Our two engineering teams are working super closely together to create a new type of server, a new type of architecture that might be super good in space and on Earth.”
Congrats on next year’s innovation! Collaboration like this is how we move the world forward. Here’s to a smarter, better future!🌎

Remember this: The pain is all in your head.
If you want to evolve, you need to go where the problems and the pain are. By confronting the pain, you will see more clearly the paradoxes and problems you face. Reflecting on them and resolving them will give you wisdom.
The harder the pain and the challenge, the better. #principleoftheday
This week:
Finding a function’s domain and range. I use a square-root example to identify the allowed inputs, bound the outputs, and prove every value in the range is reached. One step closer to calculus.♾️

How do you compute the derivative of x^x?
We use logarithms. Specifically, the natural logarithm.
Notice in the image that the domain is x∈(0, ∞), due to the properties of ln(x).♾️
News today:
In Athens, Rubio invoked the fierce individuality, ambition and spirit of discovery that helped shape the West. Greece’s democracy reminds us that power belongs with the people, not just a few. Greece and America are true allies.
World peace, not world terror.✌️🇺🇸🇬🇷

Formation of conic sections ✍️
Circle: When the cutting plane is perpendicular to the axis of the cone, the cross-section is a circle.
Ellipse: When the plane is angled, but still cuts through only one cone (without being parallel to the side of the cone), the result is an ellipse.
Parabola: If the plane is parallel to the side (slant) of the cone, it creates a parabola.
Hyperbola: If the plane cuts both halves of the double cone, it forms a hyperbola - two separate curves.
Imagine a world confined to one of these planes. Its inhabitants would experience the curve where their world intersects the cone:
A circle, ellipse, parabola, or hyperbola.
Some might take that curve as all of reality. Others might wonder what larger structure gives rise to it.

The curve y = ∛(x²) + 0.9 sin(kx)√(3 − x²) is a sine wave on |x| ≤ √3, carried by the cusp ∛(x²) and scaled by a semicircle.
Since |sin(kx)| ≤ 1, it never leaves the band between ∛(x²) − 0.9√(3 − x²) and ∛(x²) + 0.9√(3 − x²). Those two envelopes are the heart: lobes peaking at 2.27 near x = ±1.03, a point at −0.9√3 ≈ −1.56 on the axis.
Raising k only packs the wave tighter. At k = 100 it crosses the band about 110 times.
How do you find the highest and lowest values of a nonlinear function? This week’s newsletter walks through critical points, the second derivative test, and endpoint checks with a worked example.
