A group of physicists are questioning our understanding of how quarks — a type of elementary particle — arrange themselves under extreme conditions. And their quest is revealing that elements beyond the edge of the periodic table might be fair weirder than we thought.
Deep in the depths of the periodic table there are monsters made of a unique arrangement of subatomic particles. As far as elements go, they come no bigger than oganesson – a behemoth that contains 118 protons and has an atomic mass of just under 300.
That’s not to say protons and neutrons can’t be arranged into even bigger clumps and still remain somewhat stable for longer than an eye blink. But for all practical purposes, nobody has discovered it yet.

We don’t actually have a lot to be afraid of when it comes to asteroids. Sure, they might come pretty close from time to time, but they tend to buzz harmlessly by — after all, Earth is a pretty tiny target in the vastness of space.
That doesn’t mean we shouldn’t be prepared, though — and NASA, along with several other US federal agencies, has been putting together a contingency plan.
They’ve called the collective the Interagency Working Group for Detecting and Mitigating the Impact of Earth-bound Near-Earth Objects, or DAMIEN, which isn’t ominous at all, and released a 20-page document that outlines the asteroid — or near-Earth object (NEO) — plans for the next decade.

Today we will be taking a look at some of the stories people tell themselves to help them pretend aging is not a problem.
If you ask most people what they think about aging, they will shrug their shoulders and say that it is a natural process. With complete tranquility on their faces, they will agree that, yes, in old age, we are haunted by many diseases, but nothing can be done about it, so it makes no sense to worry about it while you are young and healthy. Just live your life.
Then, the conversation will turn towards an even stranger direction: they will start looking for something good about aging – for example, that it ensures a change of generations, prevents society from becoming stuck in obsolete ideas, and, in general, is the engine of evolution. They’ll explain that the notion of death gives meaning to life and makes us accomplish as much as possible in the little time we have.
Here’s the intriguing part. If you ask the same people what they felt when they first encountered the concept of aging and death from old age, they remember that they were frightened. They were not happy with the answers to “Mom, are you gonna get old and die?” and “Will I die too?” Many people remember that they cried bitterly after this conversation and were filled with sorrow for several days.

This video is the eighth in a multi-part series discussing computing and the first discussing non-classical computing. In this video, we’ll be discussing what optical computing is and the impact it will have on the field of computing.
[0:27–6:03] Starting off we’ll discuss, what optical computing/photonic computing is. More specifically, how this paradigm shift is different from typical classical (electron-based computers) and the benefits it will bring to computational performance and efficiency!
[6:03–10:25] Following that we’ll look at, current optical computing initiatives including: optical co-processors, optical RAM, optoelectronic devices, silicon photonics and more!
