How computer memory works? Why NAND, NOR latches? This video series shares insights by circuit building from scratch step by step.
In this video we will talk in detail about about how to build SRAM for high speed computing. We started with a simplest case: SR And Or latch. This simple example will help us understand the crucial feedback technique used in circuit technologies. The weakness of this simple model will give us hints on how to build more practical memory models in the future.

#FlipFlop#ComputerMemory#SRAM#LatchA pre-Calculus journey of Trigonometry-Lecture1.1: IntroductionLearning0to12024-01-13 | This course explores trigonometry through the methods used in the pre-Calculus era. It’s a spin-off from our bigger project to understand Calculus. We think it’s a meaningful experience to see how different pieces of elementary math are combined together towards a central goal of constructing a sine table. It will help us to truly appreciate the difference between elementary math and higher math later on. In this lecture we will talk about the steps needed to construct sine table.

In this video I explored a bit the topic, trying to interpret the paradoxes around it in my own way.Geometric Series and limitLearning0to12022-06-18 | As I am working on the infinite series, I realized that geometric series can be understood from the perspective of number base. Each series can be deemed as a particular decimal representation from the corresponding number base. This new way of thinking can help us understand e later.Binomial Theorem - an intuitive approachLearning0to12022-05-22 | As we are developing new courses on math, we constantly bump into interesting math topics. So we will share any topics we find interesting and useful on a stand-alone basis. But due to our resource limitation, we will focus more on the ideas instead of animations. This video is about binomial theorem, a theory useful when deriving derivative of polynomials and also finding the limit of e. This video aims to derive the theorem from scratch, rather than using existing formula without explanation.
This video series discusses the instruction set that make a computer a computer. This video talks about the second part of implementing the jump condition instruction allowing users to get out of the loop: jump condition instruction that uses the conditions set by CMP instruction. It’s a critical tool behind the looping function of any computer programming.

Ever curious about how computers REALLY work? Tired of the mumbo-jumbo on the internet? These video series might be for you. These videos aim at explaining the Scott CPU from an excellent book: But How Do it Know
There are three series. Series 1 focuses on the fundamentals like binary numbers, transistors, adders and memory. Series 2 focuses on computer architecture like Bus, sequencer, memory grid, decoders and instruction cycles. Series 3 focuses on wiring the instruction sets, it’s currently work-in-progress.

How computer memory works? Why NAND, NOR latches? This video series shares insights by circuit building from scratch step by step.
Gated And-Or Latch, this second video improves on the previous SR-And-Or latch. It provides valuable insights in helping us understand the more popular latches coming in the next video.
Why computers use 0 and 1? Why electricity is number? What is a transistor? What are Logic Gates ? How do Computers Compute ? Lots of us are curious about how computers work. But most online sources keep parroting the clichés of `0s and 1s, binary, switches' without shedding much light, leaving people more confused. Authors of this video experienced the same tortures and decided to take a non-traditional approach in tackling the issue.
Part 1 aims at a thorough understanding of binary numbers and number representations in computers.
Part 2 focuses on EXACTLY how to wire the computing circuits to build the computing engine.
