It’s Okay To Be Smart explains how and why soap is still our best germ fighter.

One of the most effective things you can do to protect yourself from catching a germ and becoming a statistic, whether it’s a global pandemic like COVID-19 or just every single other day of your life, is something that people have been trying to get you to do since you were like 2.

Wash your hands. With good ol’ soap. And do it the right way. That’s it.

Here’s the science of handwashing!

Why is it that we can see these multiple histories play out on the quantum scale, and why do lose sight of them on our macroscopic scale?

Many physicists believe that the answer lies in a process known as quantum decoherence.

Does conscious observation of a quantum system cause the wavefunction to collapse? The upshot is that more and more physicists think that consciousness – and even measurement – doesn’t directly cause wavefunction collapse.

In fact probably there IS no clear Heisenberg cut. The collapse itself may be an illusion, and the alternate histories that the wavefunction represents may continue forever. The question then becomes: why is it that we can see these multiple histories play out on the quantum scale, and why do lose sight of them on our macroscopic scale? Many physicists believe that the answer lies in a process known as quantum decoherence. 

It’s not surprising that the profound weirdness of the quantum world has inspired some outlandish explanations – nor that these have strayed into the realm of what we might call mysticism.

One particularly pervasive notion is the idea that consciousness can directly influence quantum systems – and so influence reality.

PBS Space Time examines where this idea comes from, and whether quantum theory really supports it. 

If you’re in the AI space, you’ve likely already have heard of Deep Fakes, a highly realistic generated video powered by GANs. This week, they are the subject of a House Intelligence Committee hearing on Thursday. As Miles O’Brien reports in the slightly panic-mongering news segment, the accelerating speed of computers and advances in machine learning make deep fakes ever more difficult to detect, among growing fears of their weaponization.
