Which Vax?

Quoted By: >>14245481

Everyone keep telling me to get the vax including my family so I decided to do it as if I even died by covid at least no one blames themselve for not forcing me to take the vaxx so maybe I'd lived (dumb argument but it is what it is).
What we have here is Pfizer,AZN and Sinopharm
which one is the least harmful for the body?

OP here,I got it too
took about 7 days :/
but in all seriousness the vaxx does not stop the spread so vaxx worshippers can btfo
question is does it turn a hard covid to a mild one?
or it's a meme too?
if you have any statistics on this please do share.

Or maybe another possibility is that electric fields could still exist. Functionally I think all matter would still fall apart however two possible things could happen: Either all electrons will suddenly rush into equilibrium in a giant matter dissolving lightning strike. Or without the accompanying magnetic fields, electrons effectively become waves and the universe just bathes in random electrical oscillations for the rest of eternity.

Is the abatraction to much if we take natural neural networks and put the principles into computers? I.e. assign 3D coordinated to neurons and assign links to each neuron with a certain length etc.

Was there a QRD on the Starship presentation? I was watching but Musk was retreading the same multiplanetary/self sustaining talking points again and it was incredibly boring.

Someone asked a question about E2E starship and musk didn’t seem very confident saying there’s potential for cargo flights. Is passenger E2E officially dead?

For any differentiable function
$f'(x) \\ = \frac{1}{2} f'(x) + \frac{1}{2} f'(x) \\ = \frac{1}{2} \lim_{h \to 0}\frac{f(x+h) - f(x)}{h} + \frac{1}{2} \lim_{h \to 0} \frac{f(x+(-h)) - f(x)}{(-h)} \\ = \lim_{h \to 0}\frac{f(x+h) - f(x)}{2h} - \lim_{h \to 0} \frac{f(x-h) - f(x)}{2h} \\ = \lim_{h \to 0}\frac{f(x+h) - f(x-h)}{2h} $
The advantage of the symmetric differential quotient is that it converges much faster than the one-sided differential quotient.

Here's a pretty easy solution I found. I'm skipping steps, but here's the sketch.

Group the first and the third terms to form (a^2+c^2)(b^2+c^2). Writing b=2-a shows that on the interval [0,2] the maximum value of the expression is when a = 0 or a = 2, giving a maximum value of c^2(c^2+4). Similarly, the second and last terms have a maximum value of d^2(d^2+4). So, the entire expression is at most c^2(c^2+4)d^2(d^2+4).

Writing d = 2-c and using some basic derivatives shows that there is a local maximum at c=d=1 on the interval [0,2]. This maximum gives a value of 25. Done.
