nice blog post

When talking about dreams just describe the feelings, the content is pretty useless.

Your nightmares as a kid might have been terrifying but i had the same thing while awake, lasting hours and persisting after i left my bed from fear. I only say this because those same nightmares wouldn't scare me today, despite the complete lack of control i felt, today i would cope by realizing that it is not real, i have more life experience that would anchor me to reality unless of course it was a psychotic episode.

I also want to add that the dreams i have today that terrify me aren't nightmares. They are bizzare, exploit some fear i have about life, existential, social, or personal. They are just scary enough to not wake me up but when i do wake up i feel "bad" and remember the dream in a dysphoric sense.

What this tells me is that dreams have real implications for current personal feelings, but determining what that means is entirely up to you.

Personally i dont think you are a good person. i think you should consider the possibility you are a psychopath and maybe even a sexual deviant. Do not reproduce

I've started to look at dreams as training in a simulation.

My problem is that I usually recognize that I'm dreaming then wake up.

What's weird is that if my "real" body is in the presence of external stimuli while I'm sleeping, these stimuli are seamlessly incorporated into my dream. I can feel/hear my fan in my dream. If my "real" body is too warm or cold, I have these sensations while dreaming (usually a warm or cold setting in the dream).

I've also woken up in the middle of a dream to experience sleep paralysis. I could only move my eyes to look around my room. Shit was scary as fuck. I just closed my eyes and went back to sleep like 10 seconds later.

Also if my alarm wakes me up in the middle of a dream, sometimes I can hit the snooze button and go back to sleep and continue where I left off in the dream.

I can't help you with either of those pleb-tier sciences, but I can explain this with semiotics.
When you where a child the cheesy Native American motifs at the strip mall seemed legitimate to you because you, as a naive child had not yet learned to recognize them from legitimate Native American architecture. When you saw teepees and the geometric patterns, these are the representamines you identified from the object(the strip mall) all the cheesy parts of the mall you had not yet learned to recognize, so while part of the object they were not representamines, this is how you got the interpertant "relic of the past, filled with tribal native motifs, watch towers, and tee-pee settlements, which was no doubt created by skilled Native American craftsmen long long ago" from the object "shitty brown strip mall with zigzaps on the walls, with a couple fake plastic tee-pees on the roof"
There is a lot more you do not see, for example people who are not taught to recognize the color blue, cannot see the color blue, it's just meaningless background information to them. Everything you interpret is constructed from meaning. There is nothing more than what you know.

You pretty much have to be a grammar nazi when it comes to constructing a proof.

There are 2 barriers you face when writing the proof.
1) Is it a correct proof?
2) Is it communicated in an understandable manner?

It's like programming, to an extent.

Make sure you include all of the necessary dependencies (all of the mathematical machinery you are using).

Make sure your notation is adequately defined (many people use the same symbols for different things and different symbols for the same thing).

Sometimes small "toy" examples are useful for illustrating your construction by showing how the machinery works together.

Aim for zero ambiguity in the words you use. Prefer latin words over Germanic ones (assuming you write in English). Never write anything in the first person. Don't use parentheses (use commas instead, or footnotes in extreme cases). Use "iff" when giving a definition instead of "if." Use quantifiers ([math]\forall \exists[/math]) only when the symbols you are introducing will not be used outside the formula using them. Put quantifiers on the beginning of formulas to keep them consistent with left-to-right reading. Use [math]\cdots[/math] as rarely as possible. [math]\Rightarrow [/math] meas "if ... then" and not "then" which must be written in plain letters. Don't fallback to [math]\left( \varepsilon,\, \delta \right)[/math] when you have theorems that can avoid introducing new symbols (it starts getting confusing above seven symbols). Write numbers in plain letters unless they are considered as mathematical objects or measures.

*25% anglo-franco in the second option

>>9103827
that's not a genetics question.
but the answer is 25% italian + 25% italian + 25% english + 25% french = 50% italian, 25% english, and 25% french.

>>9103834
But the punnet square would have the second option as the answer. Also, what if Italian is a dominant trait? then the offspring would be 75% italian

That's a nice 50% efficiency rate, but the current applied use makes me laugh my ass off.
>"These self-cannibalising machines would feed off their own structures, then self-destruct after mission completion."
What the fuck. I mean, it isn't too bad of an idea I guess, but it's just a weird thing to picture. Drones just self destructing and eating themselves. I suppose this could be used to make structures out of materials that actually are useful upon recycling though. It seems like it would just be better off being used in commerical vehicular Fuel Cells as an actually practical use.

Multiplication isn't commutative.
I guess you're losing track of the comma during working and tacking it on at the end. Keep track of where it is, it should be in the same column all the way down.

Jesus, I must have suffered an actual stroke while going through this, I can't comprehend how I forgot 3rd grade math. Thanks.

The goat should have laid its egg already. If it hasn't yet that means the egg is stuck and will have to be squeezed out.
Simply compress the middle of the goat until objects start emerging from it. Continue until the egg appears, then return any non-egg objects or fluids to the interior of the goat.

Totally got me there, they did not.
The theory proposed by some scholars is that it's observed in abnormal people and it indicates a defective mind. But I'm guessing it manifests in "normal" people as well. I remember having it from a young age, and I have almost no suicidal thoughts. What do you think it could be?

>>9103706
Time and size (length), as quantities are connected by speed, as a quantity. Assuming a conscious being with a brain that works roughly the same as a human's, but much smaller at size, then the communication between its neurons (its thoughts) should be faster.
Also, this random guy called Einstein, or something has some theory about relativity, I heard. It concerns space and time and everything...

The /sci guide on Google guides provides alright info, also read on high school grade books as they cover most topics.

If you do not have a Ph.D. in Pure Mathematics then you are a brainlet. This has always been the accepted definition.
