>If we really went to the moon in 1969

What the fuck are you talking about?

1. I was born in 1993. Sure as hell haven't made any trips in 1969.
2. Do you have any idea how much traveling to the Moon costs? A poor student like me can only dream of such things.
3. I'm pretty sure you and I have never met each other, and hence we can't have been on a trip together.

Check your medication.

It is not the first time an American agency is doing this. The CIA, for example, spreads flat earth propaganda (source https://www.youtube.com/watch?v=tBguu3khYhk). Therefore, I agree with >>8765841 on not having visited the Moon.

I'm not very clever /sci/, and I don't understand why 0 raised to the power 0 is 1.

It's easy to show how any number greater or equal to 1 produces 1 when raised to the power 0, take for example 2.

[math] 1 = \frac{2}{2} = \frac{2^1}{2^1} = 2^{1-1} = 2^0 [/math]

This obviously cannot work if we want to show that 0 to the power 0 is 1, since it's false that

[math] 1 = \frac{0}{0} [/math]

How can it be shown that

[math] 1 = 0^0 [/math]
19 posts and 2 images submitted.
>>
0^0 = x implies log (0^0)=log x

but log (0^0)=0*log(0)=0

so log x=0
so x=1
>>
You can't prove it. [math] 0^0 [/math] is not defined. However [math]\displaystyle \lim_{x\rightarrow 0} x^x [/math] can be shown to be 1.
>>
>>8769169
this implies, first, that you can take the log of 0^0, second that 0*log0=0, assuming, again, that log0 is defined.

This is the proper way:

let x>0, x^x=y>0. Then log(x^x)=log(y). So xlogx=logy. Take the limit x to 0. Since polynomial decrease is faster than logarithmic decrease (can show this via Taylor series, well known result), then the limit is 0. Hence logy=0 so e^0=y=1.
Q.E.D.

not a /sci/entist but i got a question:

we experience time in a forward motion. but according to the laws of physics, nothing prevents us from reversing the velocity. what does this mean in relation to free will seeing as spacetime is relative in the eye of the beholder?

i'm confused

>>8768628
i mean theoretically, according to this fella:

>>
>>8768624
The law of entropy mandates a forward flow of time.

with science and math would it be possible to legit finally weaponize ants more specifically fire ants for that matter?

yes this is a very important scientific research question I am asking here because I want to know what it would take to create such a thing.

Why would we weaponise ants? Have you ever seen the scene from the 200 hit classic starring Ben Stiller, where Ben Stiller, also known in the movie as Larry Daley in the movie, gets hit with small arrows shot at him by miniature people? The movie was innovative when it came out. Fairly uninteresting plot, but a fun concept. The characters were so-so, but all in all, I'd see the movie in cinema again if I had the chance.
5/7, I would see it again.

Sup /sci/

I'll pay somebody $5-$10 dollars via Paypal if they can help communicate how my tortilla chip warmer invention could work, in detail:

https://docs.google.com/document/d/14cT4ORjnItAb7gNHMZXX9oiFGrOkuOjKGdbkcc_PAP8/edit?usp=sharing

>
The device would be an upright tube with a heated bottom. The consumer would open the lid, pour the chips inside, and press a single on/off button to activate underneath heated coils as well as a fan underneath them. The fan would blow wind underneath the heated coils, in turn blowing hot hair to warm the chips atop. Once the set heat temperature is reached, the temperature will drop to a very subtle low-baking temperature - this will allow the consumer to leisurely pick up the chips at a relaxed pace, rather than immediately grabbing them upon being heated.

Does anyone else get spammed to fucking death by rogue open access journals?

Pic related (also pretty /sci// related in general). I get at least 10 of these a day.

These journals often perform little to no peer review, and charge a lot for publications. This is the flip side of open access: it provides the wrong incentive to publishers. Instead of selecting articles for quality, they are incentivized to accept everything, and as quickly as possible, because that's the source of income (rather than subscriptions).

Discuss.

yeah me too. it started after I signed in at a huge conference some years ago. I guess they sold my data to those cheap rat shops. sucks really really bad.
>>
>>8766205
That's pretty bad, pretty sure you could sue them for that. It's also possible that your email address got listed on their website somewhere, I'm pretty sure these rogue journals use web crawlers to find email addresses.

For me it started after publishing a high impact paper, where my email address is listed as the address of correspondence.
>>
Everyone who has ever published a paper or conference presentation gets spammed by open access journals on the email address printed on the paper. Deal with it.

Just read about Nikodem Poplawski and his "in every black hole is a universe and universes are nested in each other through black holes" thesis. This shit is so cash, honestly. It feels like taking drugs the more you read stuff from him and you more you think about it. It feels like reality is like a wonder world, a world created with the phantasy of a child where magic can happen. And he even things one can transmit information into the universes in the black holes, meaning theoretically, if there was intelligent life in our parent universe, they could have sent us messages or could even currently be sending messages. Of course the probability for this is very low but the theoretical possibility is there if he is right. Just remember his name and give him a few more years to work on it. At some point he will be regarded as the new Einstein.

Does anyone know any good and factual stuff on this subject and any legitimate and factual sources? No, I'm not doing College work on this, I'm actually just curious since when I google it, most results talking about are unfactual and misleading websites. And I do mean for averages, since you can of course have a messed up face and still be above average.

Humans developed cooking so food was easier to chew, the result was less investment into the muscles and mandibles and more investment into the brain.

So people with large jaws and small foreheads are brainlets basically.
