Writing on public park grass fields? Anonymous 21/12/30(Thu)11:37 No. 17991 ID: 706068 [Reply]

What is the best way to write on a public park grass field? (I'm not thinking about proper lawns nor meadows for grazing.)

Methods that I won't even consider is plant-killer chemicals, burning or even cutting the grass. So what's left is planting flowers and/or fertilizing the field.

So what's the best seeds, fertilizer and deliver method?

I think people have done similar shit with moss. I have no idea how you would go about growing moss as they don't even have seeds.

And moss grows slowly and only on lichens. But maybe some kind of fertilizer and seed mix? I want the seeds to sprout so quick that birds doesn't have time to eat them.

Thanks to Harvard we are now allowed to talk about how certain people from India will fire you because you are not in their caste. Look at your company org chart and you will mostly see managers from india only seem to hire other people from india that are in their caste. There are some smart people from India but this racist behavior has to go. tps://www.nbcnews.com/news/asian-america/harvard-adds-caste-bias-protections-graduate-student-workers-rcna7279

Self-contradiction. It was about dalits.

You can be both smart and a castist.

Just as Cantor's theorem shows there is no set of all sets, there is also no set containing all truths.

Or to put it another way: it's a truth that all truths can't be collected up into a totality.

No wait, I might have misspoken my second part:

That being said, I still stand by my point that I wouldn't want to work in any set theory without a set of functions between any two sets.

I don't buy this argument
consider a finite set {1,2}
then 1 is in {1} {1,2} and not in {2} {null}
and 2 is in {2} {1,2} and not in {1} {null}
The powersets are generated by the elements of the set.
This is like saying that there is no vector space basis of primes (2,0...)x1+(0,3,...)x2+(0,0,5,...)x3+... = v = (2,3,5,7,...)

You mean technical schematics, sorry but those are classified.

after the understanding of pemdas. the best thing you can do is MEMORIZE identities/ where identities are coins, the coins being equations, and the faces the sides. these dualities can exist in flux while the parts are in place. after you memorize these you must cement them in your mind... for they are the math you seek to understand.

its unpleasant but math is a language of intuition. and probably the hardest to grasp.

Why is the racial intelligence gap so taboo?

You even mention that 70,000 years of evolutionary divergence in separate environments MIGHT have played a role in differing powers of intellect and reason and you're basically blackballed.

>IQ is used as a measure of intelligence by psychiatrists and clinical psychologists across all ages
Considering it has zero purpose but to classify and label people (you can't improve your IQ), knowing it doesn't help adults do anything. It would be like saying that a person's fingerprints are "used" by psychiatrists and psychologists. They are not, and IQ is not.

It helps inform public policy decisions, and may be used by high IQs to interact with low IQs in such a way that they benefit from the exchange.
It is far easier to push oppressive policies on a segment of the population that literally lacks the capability for coherent thought.

A major unresolved issue when dealing with the origin of life is that prebiotic syntheses invariably generate very heterogeneous solutions of organic compounds. This makes it impossible to imagine how ordered linear polymers, amino acids and nucleotides could be assembled. Prebiotic chemistry could produce a wealth of biomolecules from nonliving precursors. But the wealth would become overwhelming in the prebiotic soup and one cannot fathom how organized chemical processes could emerge from such a mess. At the heart of this problem is a dreary and vicious circle: what would be the selective force behind the evolution of the extremely complex translation system before there were functional proteins? There could be no proteins without a sufficiently effective translation system. How a random collection of proteins would assemble themselves into some kind of proto-cell capable of primitive replication is not even remotely answered. Modern cells require hundreds of proteins carrying out specific tasks when assembling a new protein molecule and if only a small portion of them were crudely made it is impossible to manufacture a new cell. The cells translational system is highly dependent on accurately made proteins and a faulty translational system is by default a biochemical paradox in evolutionary terms. A primitive cell is faced with an impossible task: in order to develop a more accurate translational system is has to translate more accurately. Each imperfect cycle introduces further errors and the cyclical nature of self-replication in the cell means that imperfections lead to autodestruction. A complex system like a cell cannot be gradually achieved because of its many complex and perfectly coadapted proteins.
