LearnHarness is an open-source AI agent that first finds your exact knowledge gaps, then builds a custom learning path and teaches one reasoning step at a time.
It turns AI agents into a personal tutor that:
- Probes your current understanding
- Maps the shortest path to your goal
- Teaches step-by-step with checks
- Stores concepts in a knowledge graph
It also saves everything as a knowledge graph so you can pick up exactly where you left off.
Math, ML, physics, programming, philosophy, papers, exams it works.
Most AI tutors just explain.LearnHarness diagnoses what you don’t understand, plans the path, forces you to think, then builds a persistent knowledge graph.

"MCMC from Scratch — Practical Introduction to Markov Chain Monte Carlo" — available at amzn.to/4bgEeSY
From the Back Cover:
"This textbook explains the fundamentals of Markov Chain Monte Carlo (MCMC) without assuming advanced knowledge of mathematics and programming. MCMC is a powerful technique that can be used to integrate complicated functions or to handle complicated probability distributions. MCMC is frequently used in diverse fields where statistical methods are important – e.g. Bayesian statistics, quantum physics, machine learning, computer science, computational biology, and mathematical economics. This book aims to equip readers with a sound understanding of MCMC and enable them to write simulation codes by themselves."
"The content consists of six chapters. Following Chapter 2, which introduces readers to the Monte Carlo algorithm and highlights the advantages of MCMC, Chapter 3 presents the general aspects of MCMC. Chapter 4 illustrates the essence of MCMC through the simple example of the Metropolis algorithm. In turn, Chapter 5 explains the HMC algorithm, Gibbs sampling algorithm and Metropolis-Hastings algorithm, discussing their pros, cons and pitfalls. Lastly, Chapter 6 presents several applications of MCMC. Including a wealth of examples and exercises with solutions, as well as sample codes and further math topics in the Appendix, this book offers a valuable asset for students and beginners in various fields."

most people think mathematics is about being good with numbers. it isn’t.
mathematics is the discipline of seeing patterns.
• patterns in change.
• patterns in structure.
• patterns in logic.
• patterns in uncertainty.
build a mathematical mind by Albert rutherford argues that mathematical thinking is a skill, not a talent.
you develop it by asking:
• what stays the same?
• what changes?
• what repeats?
• what constrains the system?
• what is the simplest rule that explains this?
that is why mathematics reaches so far beyond the classroom.
the same pattern-recognition machinery powers engineering, programming, physics, finance, and science.
a mathematical mind doesn’t memorize formulas.
it learns to compress complexity into structure.

physics feels hard because most people learn it as equations floating in air.
but physics is really about state, change, functions, and constraints.
that is why functional programming fits physics so well.
Scott N. Walck’s Learn Physics with Functional Programming is interesting because it forces you to think like this:
→ a particle has a state
→ forces transform that state
→ time evolves the system
→ equations become executable models
→ abstract laws become simulations
haskell is not just “another programming language” here.
it trains your brain to think in pure transformations.
no messy mutation.
no hidden state.
no hand-wavy intuition.
just:
input → function → output
which is basically how much of physics wants to be understood.
you stop treating formulas as things to memorize.
you start treating them as machines.
gravity becomes a function.
velocity becomes a derivative.
energy becomes a conserved structure.
motion becomes an update rule.
fields become mappings over space.
this is the real benefit of coding physics.
not “learning programming.”
but forcing your intuition to become precise enough that a machine can execute it.
that is where real understanding starts.

BREAKING NEWS: SOME ANC MEMBERS CALL FOR THABO MBEKI'S RETURN AS PARTY PRESIDENT AMID DECLINE IN SUPPORT
JOHANNESBURG - Some ANC members are calling for the return of Thabo Mbeki as the President of the ANC to revive the party following its declining support in both the 2026 Local Government Elections and the 2024 National Elections.
The calls come after the party's devastating showing in Wednesday's local government elections, which has deepened concerns about its future. Supporters of the ANC argue that Mbeki's leadership could restore discipline, credibility and voter confidence. The ANC is yet to respond to the calls.

Kenneth Copeland is a preacher reportedly worth up to $760 million. He owns three private jets, and he says regular passengers are the reason he can’t fly commercial.
In the video below, a reporter catches him in his car and asks him about it.
In an old video with another preacher, Copeland explained why he won’t fly with ordinary people. He said he didn’t want to get into “a long tube with a bunch of demons.”
His ministry’s 1,500-acre campus near Dallas–Fort Worth has its own airstrip and hangar. One of his jets is a Gulfstream he bought from Tyler Perry.
When Inside Edition asked how much he paid for it, he said that was none of her business. Then he denied ever calling people demons.
His followers are mostly ordinary people who send donations to his ministry. Most of them have never been on a private jet.
Would you still give money to a pastor who calls people like you demons, or would that be the moment you walk out?

“So this person who’s wearing an ANC T-shirt, who’s carrying a big ANC title is not ANC. It’s a person who was infiltrated by the old order into the ANC and their task is to repeat what their handlers tell them to repeat.” - President Thabo Mbeki on ANC being infiltrated by reactionaries, apartheid spies and policy askaris. 🖤💚💛
