This sounds frustrating, but I'm a bit concerned how hostile you seem towards a foster child.

I think you're going to need to enlist the help of some psychiatrists, councillors, doctors, etc. that particularly specialize in childhood development. I think trying to get a kid with severe ADHD to "shut the hell up" is not the right approach and could have some very negative consequences in terms of their development and could even backfire in terms of acquiring the social skills you wish for them to have.

"I felt overwhelmed and would take ages to leave the house"

I identify with this so strongly and my friends and family have commented on it as well...

Unfortunately I don't have an iPhone. I would love to try it if you ported it to a web app though!

You can't actually "see" DNA itself because it is smaller than the wavelength of light. Those groves are 50nm and the wavelength of blue light is about 480nm.

So how then are the images generated?

It uses a technique called Fluorescence Microscopy: https://en.wikipedia.org/wiki/Fluorescence_microscope

You essentially stick some special molecules on the DNA that absorb light in one frequency and then they emit light in another frequency. So you blast the molecules with light of one frequency and then use a dichroic mirror to filter that light out and you only see the emissions and thus you see where the DNA is, but you don't "see" the DNA itself.

Like STM itself what we mean when we "see" something at those length scales is interesting. Scanning Tunnelling Microscopy is like a blind man reading braille - not really "seeing" anything but getting enough info to describe the picture.

All of those mentioned in the article were not just attendees but community organizers. Do some drake equation style math on the back of an envelope:

What percentage of young people will die in a given year?

What percentage of those will happen to be community organizers?

What percentage of those will die by being shot in the head in a car that was then set on fire to annihilate forensic evidence?

Doesn't take too many steps out to get into the realm of zero percent probability that this is random chance

Many organizers of protests in Furguson, peaceful or otherwise, have since been found murdered in ways that suggest they were literally hunted down and killed for their involvement. Multiple have been found shot through the head in burned out cars to destroy all evidence. If they broke the law it still does not merit being executed in the street. (https://www.nbcnews.com/news/us-news/puzzling-number-men-tie...)

In a situation where police feel justified to kill extra-judicially over a possibly fake 20 dollar bill, what hope do we have that protesters won't be targeted in unfair ways? Or worse, that organizers won't be hunted down like animals and murdered like in Furguson? It would be unethical to not do everything in your power to protect those in this position.

secondly how do you plan to identify violent vs non-violent protesters from a static image? How would you find their identity afterwards? There is overwhelming evidence to suggest these methods are at best ineffective and at worst racist, and in either case will lead to innocent people being charged.
