Get ready for a #MathAdventure! Ever stumbled upon Fermat's Last Theorem? It's a 358-year-old riddle that kept even the most brilliant minds guessing. Today, let's unravel this enigmatic tale of numbers, and celebrate the genius who solved it - Sir Andrew Wiles.
Pierre de Fermat was an amateur mathematician. In his book, he made a bold claim: No three positive integers a, b, and c can satisfy the equation aⁿ + bⁿ = cⁿ for any integer value of n greater than 2. (2/16)
But here's the kicker. Fermat added, "I have discovered a truly marvellous proof of this, which this margin is too narrow to contain." And just like that, he left the world pondering. What was this elusive proof?(3/16)
Go is a programming language that comes with a rich standard library containing many useful packages and modules. In this, I provide an overview of the standard library modules in Go.

If you're struggling to become a data scientist...

There's a 95% chance you are doing it wrong.

Master these 5 things to escape career boredom (and make 6-figures).🧵

#datascience #career
Would you believe me if I told you it took me 5 years to become a data scientist?

I've consulted for S&P Global, MRM McCann, and 3 more Fortune 500 companies.
But I made 5 critical mistakes that I want to teach you how to fix.

1. I was too focused on #DataScience

2. I couldn't relate it to the business

3. I struggled to communicate the value
“I am convinced that the reason the John Nunn never became world champion is that he is too clever for that. He has so incredibly much in his head. Simply too much. His enormous powers of understanding & his constant thirst for knowledge distracted him from chess”
Magnus Carlsen
Dr. John Nunn: at just 15, he began his journey in mathematics at Oxford & became the youngest student in 500 years. By 23, he earned a PhD in algebraic topology. Nunn went on to become a world-renowned chess grandmaster, dominating for almost 2 decades.

#Chess #oxford #Math
GM Nunn is recognized as one of the leading chess problem solvers, won 3 world championships in this field. He represented the British team in various solving competitions. In 1985, he published a book entitled "Solving in Style," which delves into this subject in greater depth.
Awesome article! And: take just about every single thing written about the coaching and learning of sports here, and hit ‘find/replace’ for math, and you have more of the full picture of what’s going on with #math instruction.
I’ll elaborate some parallels here: “Strict, militaristic discipline and authoritarian power with frequent outbursts of screaming and cursing” — “Strict, “get it right the first time” focus, authoritarian pedagogies with direct and indirect messages that demoralize students
“Winning at all costs” — increasing test scores at all costs
Another Fed Meeting, another decision based on flawed metrics. One of them is the new CPI. Or shall I say the *New New CPI*?

Because the calculation has been sneakily adjusted again recently, and yes, it matters. Why and how?

Time for an inflation 🧵👇
🧐 Current CPI

First, for those who are new to the whole Fed Shell Game, or if you need a little refresher, a quick review of CPI:

The Consumer Price Index, also known as CPI, is the benchmark for U.S. inflation as calculated by the Bureau of Labor Statistics (the BLS).
You may have noticed recent controversy about the accuracy of the CPI and whether the BLS is understating inflation

People ask every time a new CPI reading is released: how can the prices of groceries, cars, houses, be so inflated, yet the CPI rises only a fraction of that?
In addition to Alan Turing developing the first modern computers, he also ventured in the realm of mathematical biology.
Turing patterns explain how patterns can emerge from seemingly homogeneous or random systems. See next (1/3)
#Science #Math #Biology
By solving Reaction–diffusion equations, he showed how patterns in nature can arise, such as stripes, spots, and spirals. Turing patterns have been observed in the formation of the coat patterns of animals such as zebras, leopards, and many more! (2/3)

Machine Learning is hard.

I felt like quitting whenever I get baffled by the amount of information to learn.

But I followed the path to learning from Math for ML.

Here are the 5 critical reasons why you should start with Math concepts for ML

🤔 Why Math for ML:
**********************
📌 Machine learning algorithms rely on mathematical calculations to make predictions and decisions
📌 Many machine learning techniques, such as neural networks and deep learning, are based on linear algebra and calculus
The interesting part about the numbers in the square of Saturn is the grid.

3x3 > 33

Or every number if you like mathematics like me.
Every result is 15 in square 4+9+2 = 15

15th prime is 47° the masonic compass.

Saturn is alot at the moment will add alot to this thread just about math and geometry.
And why and how.

Interesting part here > grid is 3x3 this fits 3 times in the grid just by the numbers.
WTF Is...#DeFi

🏦 Finance penetrates all areas of our lives, but traditional finance (TradiFI) often lacks transparency, accessibility and accountability.

🌐 Decentralised Finance or simply 'DeFi' aims to solve these and other issues...but WTF exactly is DeFi? 👇
In Traditional Finance today, people are forced to keep their money in banks and other centralized institutions, having very little control over how those assets are actually custodied and managed.

Enter #DeFi:
• True digital ownership
DeFi uses #blockchain technology to make sure there is no single party in control and no single point of failure.

Additionally, everyone with a device connected to the internet can interact with #DeFi 24/7 from any point of the world.

#DeFi banks the unbanked.

THE MISGUIDED BELIEF BELOW IS THE #1 MOST DANGEROUS RISK TO YOUR WEALTH. THE ASSUMPTION THAT AN UP 20-60% YEAR AFTER A DOWN 20-60% YEAR LEAVES YOU WITH THE SAME AMOUNT OF MONEY IS THE MOST OFFENSIVE ASSUMPTION TO BASIC #MATH EVER. “VOLATILITY DRAG” IS REAL!

WHY IS NOBODYYYY TALKINGG ABOUT THHHHIISS?
You know why Powell keeps getting letters?
It's not about the coming unemployment, it's because he's in process of blowing up the Federal budget as interest on debt is heading towards over \$1 trillion a year in a freakin' hurry.
#math
Interest on debt is now the same size as the annual US military budget, which is by far the largest item in the US discretionary budget. And it's only going to get larger.
Let that sink in.
In this thread we are going, finally, to implement Navier-Stokes simulation in Niagara. We should obtain something like in the gif below. #ue5 #niagara #vfx #gamedev #math
Following the steps in Stam's Stable Fluids paper, let's split our original problem into smaller ones. Basically, we solve the momentum equation (apply forces, advect velocity and diffuse it) and after that we force that computed velocity to be divergence-free using the pressure.
We know how to solve (from the previous thread...more or less) all the elements of last picture, except maybe the "advection" step. Luckily, it can easily solve using a method called "Semi-Lagrangian scheme". Again, I recommend you take a look to @nvidia GPU Gems blog.
It's time to solve some fluid dynamics equations! These are the well-known Navier-Stokes Equations which describe the motion of a viscous fluid. #ue5 #niagara #gamedev #techart #houdini #math
There are three or four unknows in this system of equations, depending on whether we are in 2D or 3D case. The main unknows are: the velocity (two or three components) and the pressure.
The first equations, one for each component of the velocity, are called "momentum equations" and are basically Newton's F=ma applied to a little fluid element. The last equation is the "continuity equation" and it means that the flow is incompressible, i.e., density constant.
Ever wondered what a fake journal in #mathematics looks like? Follow me down the rabbit hole. I'll show you one that slipped on the slippery slope of #goldOA. #openScience #math #fakeJournal #openAccess. 👇🧵
Let me introduce you to ejpam.com/index.php/ejpa…, the European Journal of Pure and Applied Mathematics (EJPAM).

1/ Just read @paradigm's blog on GOO: @artgobblers & its inflationary token Goo.

Some interesting game theory & neat #MATH tricks just fit together in the design.

Anyways, here's how you can earn the highest Goo emission rate. 🧵👇
2/ If you don't alr know what Goo is, just read this thread by @_Dave__White_.
3/ To get the highest Goo emission rate, first we need to understand that Goo emission is based on:
- Each Gobbler's multiplier
- Goo amount allocated to each gobbler (can be different)

The Goo emission rate will then be `sqrt(m*a)` , where m=multiplier and a=allocation of Goo.
What if, and just go with me here, @AndrewYang, there were more effective ways to change the system than launching a third party named after your book with you as the figurehead?
Like, maybe the biggest problem with the system isn’t two parties, it’s the fact that all American voters don’t have an equal representation in their federal gov’t and that’s if they can register at all while one party actively tries to reduce the number of eligible voters who do
And again, @AndrewYang, these two slides do not show what you keep arguing they do. They show that 60% of the country is left of the moderates AND Republicans have consistently gamed state legislatures to prevent that from showing up in federal elections.
The US debt spiral, a thread...

US Tax revenue \$4T
minus: Entitlements \$2.8T
minus: Defense \$0.8T
leaves: \$0.4T

Annual interest exp is \$400B (at historic low coupons)

Interest coverage ratio is 1X (solid CCC ratio for corps)

/2
The debt spiral accelerates as new debt is issued at HIGHER coupon.

Ex: \$30T in outstanding debt x 3.2% coupon is \$1T in annual expense...(an increase of \$600B/yr)

This is BEFORE any new deficits and a reduction in revs due to lower capital gains

/3
So the debt spiral grows organically even in the absence of new spending.

How does the treasury fund the debt spiral?

QE infinity. Pure #math.

Unless: IMF financial repression model >> YCC plus hot inflation to grow GDP faster than coupon

Either way, ALL PATHS LEAD TO #BTC

Some fun #math and #btc (thread)

5yr CDS on the USA is 20bps (20k/yr to insure 10MM of debt against default)

Total federal debt for USA is \$30T funded plus \$160T unfunded

20yr CDS equiv is 80bps so:

\$190T debt x .8%p/a = \$1.52T premium

#btc mkt cap of \$375B

/2
/2 #btc can be considered default insurance on a basket of Fiats,

#btc has a value of LESS than one third the total premium for the USA,

thus you are getting CHEAP protection on the USA AND protection on ALL other Fiats for FREE...w/ no counterparty risk nor time decay.

Wow.
