So, I want to make some lactic acid, but I'm not sure where to start.
I was thinking of buying a bunch of yakult, and just mix it with a bunch of sugar.
I'm not sure if it would work.
Can anyone here give me some tips?

Just buy it online?

if you want to create a fully random system you 'must' eliminate all initial states to avoid predicted occurrences but then how to use a word like ""create"", to initialize a system like this. cause 'create' implies that there is a something has to begin and then the whole randomness would collapse or wouldn't so the 'event' that would initialize the system is the main key to know are the sequence of fellow events would be predictable or random. but i assumed here that random implies ""unpredictable sequence of events that have initiated from [unmeasurable/can't be fit into common pattern] 'created' event"".

in my opinion, bigbang is an 'created' event that initiated sequence of unpredictable events then by the time it's entropy lessen till it come to a state of wich it can be predictable and that allows us to deduce patterns[i mean maths]

but i think we can define time in terms of randomness getting less and less, but it's converse logical deduction because i used randomness to define time and time to define randomness :3

any thoughts, especially from chaos theorists?

Post ideas you've acquired from others or came to by yourself that seem incontrovertibly true.

For me it's the idea that life is like occurrences such as tornadoes and thunderstorms in the sense that these events are the product of requite physical conditions.

Life and by extension humans are just something that's occurring.

despite my disbelief in free will it seems amazing to me.

Strange ideas thread?
Close enough.
Whenever I think of anything remotely interesting I type it in my notes on my phone and usually forget about it. Here's one:
>(((We're))) all just fourth dimensional beings passing through the third dimension.
>Fifth dimensionals using fourth dimension as catalyst to pass through third?
>Fourth spacial dimensionals using time dimension as catalyst to pass through third spacial dimensions?
Excuse the crudeness. I've never used any substances for recreational, Incase you're wondering.

That is one of the most semantically vacuous sentences I have ever read.
>>
>>8723198
When you see a tornado spinning and ripping apart things on land do you not look at it as something that is simply occurring due to the right physical conditions?

I never looked at humans and myself and my behavior the same way i looked these occurrences.

But on a fundamental level we're simply occurring, like the different types of weather, due to the right physical conditions just like the weather.

How many tampons would it take to absorb all the ocean water?
10 posts and 3 images submitted.
>>
>>8723126
as many as there are in your mother's medicine cabinet
>>
The average tampon holds roughly 5 mL

There is roughly 1,335,000,000 cubic kilometers of water in all oceans on Earth.

That means there are roughly 1.335x10^24 mL in the oceans

so in the end you would need 2.67x10^23 or 267,000,000,000,000,000,000,000 tampons to soak up the oceans

Would we be able to send data into the past? Specifically, memories?
7 posts and 2 images submitted.
>>
>>8723053
Have you considered the fact that the concept of past is meaningless in physics?
Even the concept of time itself is going to have less value as time goes (pun intended) and research shows that time is linked to quantum-gravity, you can think about it as the amount of the vibrations of small particles, this explains the relation between space-time in some manner.
Also, our world is thermodynamical by definition, so the process of time, even if it was something which worths time (pun intended), would be irreversible.

Just need help with a quick math question relating to a video game I play, overwatch. One of the characters passive ability reduces damage they take by 35%. Another character can INCREASE the damage a character takes by 30%. If the charcter reduces incoming damage by 35% but then gets 30% more damage taken how much damage are they actually taking?

After that they're thinking of changing to to only 20% damage reduction. How much extra damage are they taking with the 30% increase in damage taken?

84.5%

4%
>>
>>8722966
It depends on the game mechanics. A lot of games take the percentage of the original value.

Using your example if they reduced it by 35% and increased by 30% it would end up taking 5% reduced. That's how most game do it.

But if you reduced by 35% and then increased by 30% you would actually end up with an overall reduction of 15.5%.

I suspect the game uses the first mechanic, but I really have no idea.
>>
>>8722972
so in the first 35% 30% he's taking 84.5% of the damage

in the 2nd 20% 30% he's taking 4% extra damage? Only 4? Thought it would be more. Alright thank you.

Everyone knows how to interpret a slope coefficient.

Many statistical models make assumptions about the data, such as linearity, because the models that don't make such assumptions are more difficult to compute.

Did you guys know that Newton plagiarized from Leibniz? The Eternal Anglo's rewrote history so well that Leibniz and Calculus are not even synonymous in the minds of the average college student.

Leibniz's calculus notation is the one that's used today, not Newton's. So yeah, I think he won.
But for the record, Newton definitely came up with it first, even though Leibnitz posted it earlier. Don't get me wrong, Newton was a crazy asshole and he treated Leibnitz like shit, but eventually he was right.

Plagiarism is only applicable if he was too ignorant to appreciate people who chose to help him.
Everyone has built upon what has been before. Others ignore the past to learn and die ignorant.

>Heat is essentially kinetic energy on an atomic level

How correct is this statement?
7 posts and 1 images submitted.
>>
>>8722452
If you are in high school, it's very incorrect because classic thermodynamics is concerned only with macroscopic descriptions energy transfer. The statement makes no sense because thermodynamics is independent of atomic theory

If you are asking because you are curious/a brainlet wandering wikipedia click this link https://en.wikipedia.org/wiki/Statistical_mechanics
>>
>>8722502
I read your link and it didn't give me any insight on the OP question. Heat is energy is it not? Where is the energy stored, if not in the atomic level movement?
>>
An einsteinian solid stores energy in 3 dimensional lattice vibrations, 'heat' is the mechanism that transfers energy between these objects. t thermodynamics pro
