Are viruses alive?
Can they reproduce with eachother, can we distinctly tell them from bacteria and do they have a mega structure they use to reproduce

Do viruses really been far even as decided to use even go want to do look more like? You've got to be kidding me. Viruses have been further even more decided to use even go need to do look more as anyone can. Can "alive" really be far even as decided half as much to use go wish for that?

Yes. Viruses are subject to evolution by natural selection. This is a property that all living things have and that that all non-living things do not have.

He mentioned already having the lab.

Then again, define hybrid, do you mean a person with a sunflower growing on their head? I can do that in a day or two.

They might lose a lot of brain function, but I just need to install a planter pot in their skull.

He was an expert in mathematics not only in logic. How does one git good like Godel? Most undergraduate programs don't even teach logic outside of basic "intro to proofs". The logic taught in those courses will get you no where close to the serious mathematical logic research Godel was into.

Plus Godel wasn't just a mathematical logician. He was supreme in general. How does one become a solid mathematician like him? I feel like most mathematicians alive today aren't nearly as smart as he was.

Same applies for Turing. He was apparently working in other areas of math like Lie Algebra

The scientific method has existed since prehistory, whether it was widely applied or not.

What the fuck this notation is so good, why is it not wildly used ? Do you think it has a flaw I can't think of ?

you have to draw a triangle when normal notation works fine anyways

Does it work with squares?

>>8641878
That argument is not acceptable, the proposed notation is objectively faster and clearer for every equality shown in the video and any equality I can think of.
If you can't find a case where this notation is inferior to the default one, it need to be changed.

ok so I was going to reply to an internet argument about addiction but thought I'd check my sources first, googled a bit about rat park and apparently theres some kind of vague dispute going on despite the study being older than I am.

so what the fuck is it? is there a credible argument for addiction being mind control magic after all?
7 posts and 1 images submitted.
>>
>>8641850

Yeah, addiction is physiological. When I had been presented with the rat park experiment, my professor explained that, given a healthy lifestyle, the appeal of drugs would not be that strong.

But, after getting addicted, you do develop physiological dependencies on drugs.
>>
>>8641892
nice complete lack of sources you fuckface

OP already knows the experiment and it takes 2 seconds to Google.

Don't be lazy...

Here is the wiki anyway,

Here, the matrix we use to represent [math]P[/math] depends on the linear order of [math]\mathbb{N}[/math] and on how [math]f[/math] is defined.
>>
>>8641757
>what?
I don't know whether there is a name for it.
Since [math]\leq \subset P^{2}[/math] and finite, we can place its points on a grid.
I'm going to write down what I have left on paper now.

Let's make a hypothetical scenario.

Light travels with light speed. If something is bright and one light year away, it'd take one year for the light to travel between the star and the earth.
When we look at the sun, it's about 15 light minutes away. So if you look at it, you'll see the sun as it was 15 minutes ago. If the sun exploded right now, you'd only see it in 15 minutes!
Now let's say, we have a ship and a huge telescope. We travel a couple light years and then stop. Now we look through the telescope, looking directly at the earth.
The earth is, say 10 light years, away. Since light has to travel 10 years to reach us—are we looking at the earth as it was 10 years ago?
What exactly are we seeing then? If we zoom in enough, are we actually gonna see things as they were in 2007? If we traveled enough, would we be able to see 80 years ago, looking at Hitler giving a speech for example?

I don't know anything about physics, but wouldn't you be looking at a Future Earth since light travels faster than your ship?

I dunno but in my scenario I decided that we don't travel with any speed, we just teleport ourselves to a certain place which is 10 or 80 light years away from earth.

Difficult and often costly, very hard to get good airflow, ground water becomes polluted, smoke from all the lights you need is very hard on the lungs, also apparently very noisy.

- 5 points of methamphetamine per day (smoked in a glass pipe)- so glass pipes (they don't last)
- bic lighters
- tailor made cigarettes

Keeping the rest a secret, though i am happy to discuss more with anyone willing to sponsor.

Then i will quit methamphetamine after 14 weeks, and need nothing.
