An explanation of Moore’s law, modern computing, and why it’s difficult to make faster chips
(0) | 14/07/2014 | Translate: SciShow explains how SciShow exists — and everything else that’s ever been made or used on a computer — by exploring how transistors work together in circuits to make all computing possible. Like all kinds of science, it has its limitations, but also awesome possibilities.
Read an ancient text written on a papyrus scroll without unrolling it Brent Seales, professor of computer science at the University of Kentucky, discusses his work, spanning two decades, rescuing ancient texts such as the charred scrolls of 'Herculaneum. - The world’s ugliest music | Scott Rickard | TEDxMIA Scott Rickard has degrees in Mathematics, Computer Science, and Electrical Engineering from M.I.T. and MA and PhD degrees in Applied and Computational Mathematics from Princeton University. At University College Dublin, he founded the Complex & Adaptive Systems Laboratory, where biologists, geologists, mathematicians, computer scientists, social scientists and economists work on problems which matter to people. He is passionate about mathematics, music and educating the next generation of scientists and mathematicians.
- How transistors work Modern computers are revolutionizing our lives, performing tasks unimaginable only decades ago. This was made possible by a long series of innovations, but there’s one foundational invention that almost everything else relies upon: the transistor. Gokul J. Krishnan describes what a transistor is and how this small device enables all the amazing things computers can do.
- One day, a computer will fit on a desk (1974) Science fiction writer Arthur C. Clarke makes the bold claim that one day computers will allow people to work from home and access their banking records.
- A glass table suddenly breaks A man is working on a computer when the tempered glass table suddenly breaks.
- Fixing dents on an Audi RS4 Mat left his Audi RS4 to a colleague who had the misfortune to beat him. As Mat Watson is dedicated (among other things) to making videos for Carwow, he decided to take the opportunity to document how the aluminum panels of modern cars are repaired. Aluminum is not as easy to work as steel, since it has no memory effect, and requires expert hands, a lot of eye and patience to be repaired.
- Phase-Functioned Neural Networks for Character Control We present a real-time character control mechanism using a novel neural network architecture called a Phase-Functioned Neural Network. In this network structure, the weights are computed via a cyclic function which uses the phase as an input. Along with the phase, our system takes as input user controls, the previous state of the character, the geometry of the scene, and automatically produces high quality motions that achieve the desired user control. The entire network is trained in an end-to-end fashion on a large dataset composed of locomotion such as walking, running, jumping, and climbing movements fitted into virtual environments. Our system can therefore automatically produce motions where the character adapts to different geometric environments such as walking and running over rough terrain, climbing over large rocks, jumping over obstacles, and crouching under low ceilings. Our network architecture produces higher quality results than time-series autoregressive models such as LSTMs as it deals explicitly with the latent variable of motion relating to the phase. Once trained, our system is also extremely fast and compact, requiring only milliseconds of execution time and a few megabytes of memory, even when trained on gigabytes of motion data. Our work is most appropriate for controlling characters in interactive scenes such as computer games and virtual reality systems.
- Sketchpad – CAD program in 1963 with a graphical user interface This video is a TV show made about the software Ivan Sutherland developed in his 1963 thesis at MIT's Lincoln Labs, "Sketchpad, A Man-Machine Graphical Communication System", described as one of the most influential computer programs ever written. This work was seminal in Human-Computer Interaction, Graphics and Graphical User Interfaces (GUIs), Computer Aided Design (CAD), and contraint/object-oriented programming. While watching this video, remember that the TX-2 computer (built circa 1958) on which the software ran was built from discrete transistors (not integrated circuits -it was room-sized) and contained just 64K of 36-bit words (~272k bytes).
- Modding. Custom case for computer (Battletech/Mech Warrior style). Continue work on computer case in the style of BattleTech (Mech Warrior). A distinctive feature of the Vulture (Mad Dog) have always been two huge missile launchers – in this video we are going to do... Also add a couple of sensors for temperature control on the Arduino and RGB led backlight. Time work took a lot, but I, as usual, tried to cover scope of work in the most compressed form, so as not to bore You)
- Levitate a Magnet with Bismuth Crystals – No Energy Cost, Indefinite Levitation How to levitate a magnet with no batteries, external power, or trickery. It floats on pure SCIENCE! Below are some links you can use to purchase bismuth and the magnets seen in this video, but first a word of warning: Strong magnets can be really dangerous, especially if you have more than one. The 1" cylinder magnet that I use for this project could break bones if you let your hand get between it and another large magnet as they snap together. Smaller magnets that are pulled against a larger one might shatter on impact and fire out sharp chips. I recommend eye protection while working with them. Lastly, don't purchase strong magnets if you live around anyone with a pacemaker. Pacemakers are adjusted magnetically and could malfunction if exposed to strong magnetic fields.
- A Christmas Computer Bug, and the Future of Files In 1987, a German student wrote CHRISTMA EXEC - a virus whose basic mechanisms still work if you port them to today's desktop computers. Why haven't we changed in nearly 30 years? And what could we do instead?
- Lock The Taskbar The 1982 song “Rock The Casbah” is famous for being one of the most commonly misquoted songs of all-time. Some people hear “rock the cat box” or “rock the asphalt” or maybe even “rock the dance floor.” Well, now there’s another way to hear the famous punk anthem by The Clash. You’ll never be able to right-click and lock the taskbar again without singing. It’s a new modern punk anthem for computer nerds. Enjoy having this song stuck in your head for the rest of the day.
- Guy won a car off a scratcher. Then reenact’s it for a news crew and wins something else: ) This guy had an accident at work, had a heart condition, and was near death. Things then turned - he got engaged, a new job, then won a new car on a scratchie ticket...then won money on another scratchie ticket live on camera when asked to re-enact it all! ........(1:04 - She holds the ticket up to the camera, we can't see jack s**t lol) ....... (sorry for the sound at the start)
- How Green Screen Worked Before Computers For those of us who grew up in the age of CGI, green screen is just "a thing that computers do". But how did effects like this work before the age of pixels? With the help of some suitably shiny graphics, here's a quick summary.
