Step inside the strange world of a superfluid, a liquid that can flow endlessly without friction, defying the common-sense ...

Get the essentials on static and kinetic friction forces! This video covers the key differences between these two types of friction, how to calculate them, and real-world examples to help you ...

The weather has suddenly taken a turn, and there's a chilly bite in the air—cue lashings of lip balm on chapped lips, oversized winter coats and hats to keep our ears toasty. The trouble is, as soon ...

Abstract: Cable-driven continuum manipulators exhibit high flexibility and dexterity, leading to their increased popularity in recent years. Friction analysis is a crucial problem for these ...

You probably don’t need more time. By Jancee Dunn When I look back on all the major decisions I’ve dithered over, I could scream. It took me a decade to commit to becoming a parent. I wavered for a ...

So you’ve connected a device to your PC via a USB port — but Windows doesn’t recognize it. What now? Before you assume the product (or your PC port) is broken, there are several USB troubleshooting ...

Frying a computer component with static is one of those things that very rarely ever happens. Yet it can happen, as I found out recently through personal experience — when building a new PC, I made a ...

The machine doesn’t care what it’s making—only that it’s making it fast. Frictionless systems optimize output. But meaning, memory, and margin live in the mess it leaves behind. The great smoothing is ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The nation relies on cyber systems for commerce, critical infrastructure, national security, and most facets of daily life. However, the growing scale and complexity of cyber technologies–coupled with ...
