Nature isn't healing

Let's say a a two-ton car is travelling at 60 mph and hits a brick wall. The kinetic energy of the car can be calculated by multiplying the weight by the velocity squared and dividing by two. How would you calculate the force of the initial impact? How do you calculate what goes on in impacts?

Why didn't great apes, particularly homo sapiens, retain their tails? If imagine they'd be useful for balance once we moved to walking on two legs

I know they’re coming here to make friends with the human race

I want to meet them and to greet them and to join them on their flying ships

what do you do if you have horrifical hand-eye coordination and motor skills buy you like building things or engineering shit?

I would like to be able to reopen my brain's critical period of synaptic plasticity for just a short period of time, perform a specific learning task, and then restore it to normal (or not?). Something like taking an autism pill, if you like.
So before even going further, can anyone point me in a sensible direction for this enquiry?
I think studying autism may hold the key to this; I've gotten to know some high functioning autistics / borderline autistics, and what they can do is amazing.
I'm currently reading through a superb article: Autism: A “Critical Period” Disorder? by Jocelyn J. LeBlanc and Michela Fagiolini
http://www.hindawi.c...np/2011/921680/
Although it is centred around autism, the first part is purely about the critical period of plasticity, and documents different ways to extend it. I would like to post sections here (annotated by myself), in the hope that the community may connect the various described critical-period-extension-mechanisms with their relevant nootropic compounds.
The paper says that an animal goes through a critical learning phase at the start of its life, in order to create low-level circuits. Then this critical phase is turned off, so that these low-level circuits are stabilised/fixed, and higher-level circuits can make reliable use of them.
It points out that in autistic individuals, this mechanism doesn't kick in. And so they retain low-level plasticity, at the expense of not being able to develop high-level circuits. This simultaneously accounts for their Savant capabilities, and higher-functioning (e.g. emotional) disabilities.

How likely is it there can exist a disease more dangerous than COVID-19? Isn't COVID-19 the most devastating pathogen ever? Not in terms of deaths, but in terms of how much it affected the world.

Tomorrow I'm taking the informatics olympiad, it's the county stage so the problems won't be very very very very hard but they'll still be very very hard. I am barely any good at solving them, I know some algorithms but can't figure out how to make the best of them. I'm 11th grade so all I need to know are graphs, backtracking and greedy method. Any lasy-day tips?
