It's pretty self explanatory isn't it? If there was an "automatic" algorithm for the behaviors we consider human intelligence, emotions, and creativity, AI would already exist.

I don't quite understand how vaccines work, how is it that they inject you with dead virus cells? Virus cells are neither living nor dead so how can they inject you with something that cannot die. Are viruses like the undead?

Also why do vaccines cause pain in the injection site and sleepingess?

I've always wondered does drinking alcohol after a vaccine mess up the vaccine and like kill the things in it?
>>
>>7762883
Viruses have two parts:
1) An outer shell that delivers the payload. This is the part the immune system detects.
2) A DNA payload that instructs the infected cell to make more viruses

Non-working or missing payload = can't replicate = virus is dead.
>>
Living and dead are arbitrary terms when it comes down to it as seen by things considered borderline like viruses. You could say they are inactive if you want but it's just semantics. Though as far as I know most vaccines do not contain inactive viruses so much as weakened viruses that can not reproduce as easily or cause nearly as much damage as a normal virus. Either way, the body easily eliminates the weakened viruses after which the body can then through the use of memory cells, which were formed from B and T cells used to fight the virus, can later be used by the body to quickly detect and eliminate the virus if it reappears.

Is it normal to have this abnormally big (especially the left one) frontal sinuses?

Is it normal to have painful frontal headaches day in day out?

Is it normal to often have continuous rhinorrhea and sneezing lasting up to 10 hours?

Is it normal to have horrendous stabbing headaches that make me discharge mucus with blood from my nasal cavities for a whole week after being on a plane?

Is all that normal? Because that's all I'm getting from the doctors. Everything seems to be normal.

Can someone please explain how using this mixer causes the water to spin in a way where >>7762762
Care to elaborate?
>>
eletrcomagnetic force produced by the crust of the Earth interacts with the ions in undistilled water and creates potential energy that is released when an exit is created at the bottom. That is why if you fill your bath with distilled water and let it drain, it won't create a cyclone.

Can someone tell me if these odds are worth playing? I have a friend who says, theoretically, I can always do this with him.

Pay him 25 cents to play.

Then I get to roll 3 dice.

If I get a 3, he gives me $10. There is a 1/216 or .5% chance of getting this.

If I get a 7, I get my quarter back. There is a 15/216 or 7% chance of getting this.

I get a 13, I get $2. There is a 9.7% chance of getting this.

I get an 18, I get $5. There is 1/216 or a .5% chance of getting this.

Wouldn't the dealer end up losing with these odds? Especially with the 13, at 9.7 paying $2. Also, 25 cents for a .5% chance to win $10 doesn't seem like good house odds to me, but I don't know about this stuff. I suspect he doesn't either.

Simple probability,
[math] expected winnings ($) = \Sigma (probabilities \times winnings) - $0.25[/math]
So your expected winnings is
[math] $10 \times \frac {1}{216} + $0.25 \times \frac {15}{216} + $2 \times \frac {21}{216} + $5 \times \frac{1}{216} - $0.25 [/math]
or $0.03125.

So technically you win 3 cents per round.

I used it for a period of time consistently. Hell, I've even bought the subscription for it and I also got 2 other similar apps and did "games" on them as well. I noticed no tangible benefits after weeks of using them. Though my scores did increase over time.

The conjoined twins were born in Tondo of Miya in Ganjuwa Local Government Area of Bauchi State, Nigeria over the weekend. According to Aminu Bombiyo who shared the photos, the twins were delivered at home before being brought to ATBU Teaching Hospital Bauchi. Their mother, a poor Fulani nomad named Adama Sani is seeking for assistance. See more photos...

how the fuck do you decide what you will study for the next 4-5 years? this is insane. what if you lose interest?

i'm interested in superconductors, CPU architecture, heat exchangers, propulsion systems, chemical explosives, protein synthesis, nonlinear PDEs, energy storage, machine learning/cryptography, lithography/crystallography, electroactive polymers, josephson junctions, multijunction solar arrays, all both in theory and in application. am i fucked? some anon here said do material science, electrical engineering, or physics. pic related.

This might sound like a retarded question.

But how does one gather as much knowledge as possible within like 4 years.

I've got the time, I've got the motivation. But I don't have a plan where to start.

Reading textbooks all day? Watching educational videos on youtube all day?

With knowledge I mean actual knowledge like math, physics, chemestry, biology, history, geography, languages etc., not stuff like "Who is married to Angelina Jolie?"
