Brainlets, unite.

Im 24 years old who never really studied math. Now Im learning Prealgebra from scratch, and studying about 5 hours per day. Its not easy because I never memorized the multiplication tables, but Im really enjoying the study, its so satisfactory when you see the progress.

My goal is to get good at Calculus until the end of the year.

how is cantor's diagonal argument constructive? applying it to an enumeration of all algebraic numbers does produce a transcendental number, but it's easy to give an enumeration of the reals that contains infinitely many transcendental numbers.

>>11711560
Cantor already knew this. It doesn’t matter because what matters is that there’s a bijection between the set of reals and the set of infinity binary sequences (or equivalently the set of sets of natural numbers), so proving that the latter is bigger than the set of natural numbers suffices for the former.

Also, the post you linked to is an April fool’s joke.

>>11711555

It does, so long as you're careful to deal with the subtlety that >>11711560
mentions (which Cantor did).

>>11711571

>>11711560
Decimal expansions are unique up to a terminal infinite string of 9's (which equals another expansion with terminal 0's). Likewise, a base n expansion is unique up to a terminal infinite string of (n-1). This is easy to prove by analyzing the first digit in which two decimal expansions differ.
Therefore, as long as you demand that any terminal-9 expansion is expressed in terminal-0 form, decimal expansions are unique.
>>
>>11711560
How's that argument properly refuted?
By the fact that R isn't captured by digit expansions?

Got some scientific questions regarding a Last Airbender fanfic I am writing, apologies for bringing my brainletism here but I can’t find everything on the internet.

My current understanding is that if you have easy access to 100% purity heavy water it would be pretty cheap to produce Pu-239 at the right isotopic purity for weapons. So right there you could be making fission bombs pretty easy if you had the explosives and electronics technology to get a prompt criticality. You could even do some fusion boosting the deuterium you get from electrolysis on the heavy water Is there a step in this process I am missing where effectively unlimited heavy water wouldn’t make the whole process relatively easy. As far as I could tell you would only need lithium 6 production to start making boosted weapons after this. Is there anything about this that’s retarded, don’t wanna write shit to find out the whole basis was wrong.

Anyway idea for story was that generations after aang took down ozai, the technological advancement happening in the fire nation continued throughout the world. Fearful of the fire nation the water tribes use their bending to make nukes really easily and the fire nation responds by starting a space program to harness fire bending (which is shown to be capable of thrust in the show) for spaceflight in order to put up rods-from-gods system. Then they do cold-war shit and it’s military/political drama in avatar with the cast composed of original series’ descendants.

So yeah how retarded is this?

Blessed thread.

So, thought about it for a while, and seeing the qysea recently made me curious.

Is there an issue with using a thin long wire (shielded) to extended an antenna’s placement? Since it should be low current anyway

ie: a drone with 2.4ghz and 5.4ghz antenna normally, but separate the antenna to a spool of wire with shielded thin wire connecting it to the receiver and video transmitter

It’d be neat to make something to put my gopro on - I already have radios, receiver, video transmitter etc and all that from building a drone and fpv plane
>>
>>11713132
If you mean put the antenna on a float, yeah you can do that, but coaxial cable's not that flexible. There will be loss, but as long as it's not more than a couple meters it shouldn't be too bad.
>>
>>11713167
Float might too, but a spool back at base would be good so it can be reeled In, so a lot longer than 5m

The pic related qysea drone does it.
>>
>>11713172
coaxial cable is hard to spool. And if you're not using a floating antenna why bother making it wireless at all?
>>
>>11713184
Because the receivers, and transmitters for both radio and video are already wireless, how would I plug them directly into the fpv goggles and radio controller? It’d take different hardware and would be more annoying anyway
>>
>>11713132

Just to make extra sure that you cannot hide in water when the terminators come.

Jesus never used parables that are an obvious contradiction of blatant common sense. Plants can't survive millions of years without the sun. The person who wrote that book knew that. Why would he get something so simple totally backwards? The story is not a parable of evolution. There is no way to rectify it so that you can interpret it as such...

>so yes
No, fossilization happened on many thousands of specimens with only geology being a limiting factor (and time is a factor for many aspects of fossils on top of geology) but they were not preserved or "stayed intact" as well as this unique specimen.
The evidence dictates theres another factor involved that limits a fossils ability to be preserved this well, and that factor was clearly absent in this case.

We don't know the full answer to your question OP. Don't worry too much about it. If reincarnation is real then you'll be taken care of and your body and soul will be reorganized to another part of the universe. If our existence is infinite there is a good reason why we have forgotten who or what we really are. Or death could be the end of perception. Enjoy your life while you can.

If time is infinite then our exact atomic structure has to replicate at some point in the timeline after our death right?
