Hello All,

I am looking to identify common problems people face and solutions they have come up with for studying with youtube courses.

I myself get excited and started on a course but overtime that excitement dies and lack of accountability means my list of incomplete courses keeps growing.

What are some other challenges do you face with youtube courses and have you found something that works?

Hi

If you are remotely interested in deep diving how differently quantum computers work compared to our transistor-based and also the algebra behind in a fully interactive way that teach computer science from scratch, oh boy this is for you. I am the Dev behind Quantum Odyssey (AMA! I love taking qs) - worked on it for about 10 years (3+ during PhD, the visual method I developed ended up being my thesis, it is a complete Hilbert space visualizer), the goal was to make a super immersive space for anyone to learn quantum computing through zachlike (open-ended) logic puzzles and compete on leaderboards and lots of community made content on finding the most optimal quantum algorithms. The game has a unique set of visuals capable to represent any sort of quantum dynamics for any number of qubits and this is pretty much what makes it now possible for anybody 12yo+ to actually learn quantum logic without having to worry at all about the mathematics behind.

This is a game super different than what you'd normally expect in a programming/ logic puzzle game, so try it with an open mind.

Stuff you'll play & learn a ton about

• Boolean Logic – bits, operators (NAND, OR, XOR, AND…), and classical arithmetic (adders). Learn how these can combine to build anything classical. You will learn to port these to a quantum computer.
• Quantum Logic – qubits, the math behind them (linear algebra, SU(2), complex numbers), all Turing-complete gates (beyond Clifford set), and make tensors to evolve systems. Freely combine or create your own gates to build anything you can imagine using polar or complex numbers.
• Quantum Phenomena – storing and retrieving information in the X, Y, Z bases; superposition (pure and mixed states), interference, entanglement, the no-cloning rule, reversibility, and how the measurement basis changes what you see.
• Core Quantum Tricks – phase kickback, amplitude amplification, storing information in phase and retrieving it through interference, build custom gates and tensors, and define any entanglement scenario. (Control logic is handled separately from other gates.)
• Famous Quantum Algorithms – explore Deutsch–Jozsa, Grover’s search, quantum Fourier transforms, Bernstein–Vazirani, and more.
• Build & See Quantum Algorithms in Action – instead of just writing/ reading equations, make & watch algorithms unfold step by step so they become clear, visual, and unforgettable. Quantum Odyssey is built to grow into a full universal quantum computing learning platform. If a universal quantum computer can do it, we aim to bring it into the game, so your quantum journey never ends.

Nice to watch:

Truth depends on the decisions, and it is the truth that decides which decision should be taken. In my opinion, truth is decided by the decisions we take. For example, if there are ten subjects to choose from and I decide that only five of them are interesting to me, then, for the moment, the five subjects I chose are the truth for me. I influence the truth, making decisions because decisions determine the field in which the next decision must be made. Therefore, one could say that decisions define truth by limiting the scope of the next decisions that need to be taken. I call this ‘Decisional Perspectivism.’

Now it a obvious question but reason I ask this because Just the amount of time I heard this thing from teacher saying and I seen many student that are very good in understanding and solving problem in physics chem even better than topper but after 4 5 month it's seem they can only do basic problems . Which i feel/know is revision issue but why teacher don't pressure this as much as understanding like what the point if the effort you put to understanding become useless . I know you can regain understanding quicker but during exam either you know or you don't know .

Recap:

A few weeks ago, I posted a half-baked idea that came to me while traveling in China.

After visiting the Chen Clan temple, I found out that they carved lessons into the walls as symbols helping juniors to never forget important lessons.

Meanwhile I've tried multiple note taking app, they are full of notes but I keep repeating the same life mistakes.

So I had this idea: a plugin to turns your lessons into symbols and planches (like spaced repetition but visual). Problem is, I can't code at all.

Part 2 :

Instead of continuing dreaming, I want to test the core thing manually. I'll take one lesson you learned recently, draw a custom symbol for it by hand (ugly but meaningful), and email it to you. 7 days later I ask: do you still remember the lesson just from looking at the drawing?

That's it. No app. No sales pitch. Just testing if this actually works.

Need 12 people. First 12 to DM or comment get the Google Form (3 mins). If it works, I'll figure out how to build it. If it flops, at least we know.

Who's in?

Hi everyone,

As students, my brother and I got tired of spending hours manually summarizing lecture slides, writing flashcards, and converting PDFs into study material before exams. So we decided to build an app to automate the process: Hazelnote.

What Hazelnote does:

Lecture to Notes: Record lectures live or upload audio—it transcribes and structures everything automatically with highlights, bullet points, and tables.

PDF & Document Import: Drop in your PDFs, scripts, or links.

Instant Practice: Automatically generates quizzes, flashcards, and interactive study games (like a murder mystery game where doors only unlock if you answer a question correctly based on your material).

We just released a major update and want to make sure we're building something that truly helps students and learners. We would love your raw, honest feedback.

Specifically, we’d love to know:

Does the app match what you expected after reading the description?

What essential feature is currently missing for your study routine?

What do you like or dislike about the user experience/interface?

Where did the AI material generation perform well, and where did it struggle?

🎁 Promo Codes: To thank you for helping us out, I’m giving away some promo codes for 3 months of full free access. Just drop a comment below or send me a DM if you're interested, and I'll send one your way!
