Leslie Lamport revolutionized how computers talk to each other. The Turing Award-winning computer scientist pioneered the field of distributed systems, where multiple components on different networks coordinate to achieve a common objective. (Internet searches, cloud computing and artificial intelligence all involve orchestrating legions of powerful computing machines to work together.) In the early 1980s, Lamport also created LaTeX, a document preparation system that provides sophisticated ways to typeset complex formulas and format scientific documents. In 1989, Lamport invented Paxos, a “consensus algorithm” that allows multiple computers to execute complex tasks; without it, modern computing could not exist. He’s also brought more attention to a handful of problems, giving them distinctive names like the bakery algorithm and the Byzantine Generals Problem. Lamport’s work since the 1990s has focused on “formal verification,” the use of mathematical proofs to verify the correctness of software and hardware systems. Notably, he created a “specification language” called TLA+ (for Temporal Logic of Actions), which employs the precise language of mathematics to prevent bugs and avoid design flaws.

The field of computer science summarised. Learn more at this video's sponsor

Computer science is the subject that studies what computers can do and investigates the best ways you can solve the problems of the world with them. It is a huge field overlapping pure mathematics, engineering and many other scientific disciplines. In this video I summarise as much of the subject as I can and show how the areas are related to each other.

#computer #science #domainofscience you can buy this poster here:
North America:
Everywhere else:
French Version:
Spanish Version:
Get all my other posters here:

A couple of notes on this video:
1. Some people have commented that I should have included computer security alongside hacking, and I completely agree, that was an oversight on my part. Apologies to all the computer security professionals, and thanks for all the hard work!
2. I also failed to mention interpreters alongside compilers in the complier section. Again, I’m kicking myself because of course this is an important concept for people to hear about. Also the layers of languages being compiled to other languages is overly convoluted, in practice it is more simple than this. I guess I should have picked one simple example.
3. NP-complete problems are possible to solve, they just become very difficult to solve very quickly as they get bigger. When I said NP-complete and then "impossible to solve", I meant that the large NP-complete problems that industry is interested in solving were thought to be practically impossible to solve.

And free downloadable versions of this and the other posters here. If you want to print them out for educational purposes please do!

🔍 In this video, we unravel the layers of AI, Machine Learning, Deep Learning, and their applications in tools like #chatgpt and Google #bard we first go through how AI is a broad field of study that encompasses #machinelearning as a sub-field.

We then break down Machine Learning into supervised and unsupervised models, using real-world examples to illustrate their functions and differences.

We move deeper into Deep Learning: Learn about artificial neural networks and the power of semi-supervised learning in applications like fraud detection in banking.

Then we delve into Generative AI, differentiating it from discriminative models and demonstrating its capabilities in creating new, innovative outputs.

Finally we walk through Large Language Models (LLMs) and uncover the significance of LLMs in AI, their pre-training processes, and their customization for specific industry applications

Want to support my work? You can sign up for a paid subscription to my newsletter and YouTube channel here - this video we cover enhanced geothermal and the role it could play in decarbonizing the world's electric grid.Recently there have been a series of breakthroughs in enhanced geothermal systems, an advanced method of generating electricity from the Earth’s heat. If these developments continue, geothermal could generate between 10 and 20 percent of the country’s electricity in the coming decades, according to recent studies from the Department of Energy and Princeton.Enhanced geothermal could also solve one of clean energy’s biggest problems: intermittency. Unlike solar and wind, geothermal power plants can operate at all hours of the day, no matter the weather or time of year. In this story, I’ll cover the past, present, and future of enhanced geothermal and look at what needs to happen in order for the technology to play a large role in decarbonizing America’s power sector.All sources can be found in my article on the same topic here: #technology #sustainability #geothermal #energy

LG Prada Predated the Iphone. LG Prada was released announced December 12th 2006 and sales started in May 2007.

5:43 Most smartphones use a pentile subpixel layout which is 2x Green for 1x Red and 1x Blue.

7:25 1Pixel = 1G+1B or 1G + 1R. Thus the latest phones are closer to 6.67Million itty bitty lights.

Have you ever wondered how video game graphics have become incredibly realistic? How can GPUs and graphics cards render such incredibly detailed scenes? Well, in this video we're going to explore how just a bunch of data in your computer gets turned into realistic graphics. Additionally, we'll take a quick look into Ray Tracing, DLSS or Deep Learning Super Sampling, and many other complicated aspects of video game graphics.

We at Branch Education love to play video games, so this video has been one of our favorite ones to make thus far. It's kind of like getting to look under the hood of your childhood car. Also, it was surprising that practically all video games use similar basic steps to render each frame. Furthermore, as a fun fact, to create this video our team used 1x 3090ti, 3x 3090s, and the model that we tore down was a 3090.

There are just sooooo many topics in the realm of computer graphics that we couldn't cover. If you're interested in part 2 where we'll cover things like UVs, Normal Maps, Shadows, Reflections, Specular Reflections, and much more, tell us in the comments.

99% of all internet traffic – from this video to your Pokemon Go account to your family WhatsApp group – runs on a hidden network of undersea cables. Why should you care? Because modern life is increasingly dependent on those slinky subaquatic wires. And they get attacked by sharks from time to time.
