I have a system dynamics question! Maybe you could point me in the right direction? If I have the system response to a step input, what is the simplist way to derive the transfer function? I’ve only ever learned how to use a system to do modeling, not how to reverse engineer the model.

Lemmy Shitpost@lemmy.world•Getting told by Lemmy to stop taking drugs
8·4 days agoI loved mushrooms and acid, salvia was terrible. It’s super short and super intense. You may think “well it’s just 5 minutes” but it will not feel like 5 min. If you’re looking to expand your mind, mushrooms and acid are great. If you want to slice your brain in half and put the two halves in two separate dimensions with no personal introspection to speak of, try salvia.
He looks like Creedy from V for Vendetta.

Only smile that matters
Eros Venus now, sasa?
What kind of brick is that?
Ethicists were too preoccupied with whether or not they should, they didn’t stop and think if they could.
Is oldy moldy oldy moldy?
I admit the “don’t be evil” slogan was very effective on me. I fell for it, but never again.
I’ve known a fair amount too and they always over leveraged themselves. As soon as they had enough for another down payment they would purchase another property. It could have been a different strategy or situation than the landlords you know. To the landlords I knew having aapartment vacant for two months was a serious financial issue.
Most are absolutely living month to month, not out of necessity, out of greed. Most have taken out many mortgages and are just passing the monthly rent from tenant to bank. Why pay off a property when you can just use that money as a down payment for a new property?
Just wanted to add some clarity on the term Persian. Persian is an ethnicity, the majority ethnicity in Iran. So one could be Iranian (citizenship) and Persian (ethnicity), or Australian (citizenship) and Persian (ethnicity).

Lemmy Shitpost@lemmy.world•Now that the DOW is below 50,000, are we allowed to care again?
14·2 months agoIt’s a useless metric for the state of the stock market. It’s used because it has been around forever and people hate change.
Why is it useless? It is calculated by tracking 30 companies on the stock market and pretty much adding up their current stock price. This is a meaningless metric because you could have one company that is worth $100 that offers two shares of stock, each worth $50. Another company worth $100 chooses to have 50 shares of stock each worth $2.
The companies are the same value, but their stock price is vastly different. Let’s say they’re both on the DOW list of 30 companies. When the first company doubles in value, so does it’s stock price. Now the company is with $200 and the stock is worth $100. That means the dow increased by 50.
When the second company doubles in value, it’s stock also doubles to $4. Now the DOW increases by a value of 2…
This is why the DOW is useless. It’s intent is to measure the general trend of the stock market, but with the two examples above it clearly fails at doing that. There are many better stock market indexes that provide a more reliable insight intoarket trends, the S&P 500 for example. The DOW is meaningless and anyone who is using it as a reference for the health of the stock market is an idiot.
Anyone using it to talk about the health of the economy overall is out of their gord and should be in the loony bin.

No Stupid Questions@lemmy.world•Why is #FFFFFF white, but mixing red green and blue paint is black?
4·2 months agoThis was a fantastic ELI5. Thank you for your effort in writing this up.
Shorts are unintended low impedance paths.
it’s just an incredibly tiny amount
Indicates you are not describing a short.
Sure, there is technically current flowing, but it is small enough to be considered an open circuit for engineering purposes. There is leakage current for every insulator, we don’t call it a short.
Jupiter’s Trojan asteroids sit at Lagrange points. Material found there is not counted in the ‘clearing the orbit’ criteria. They are in stable orbits caused by the mass of the planet in question, not in lieu of a massive enough body.
You can boil whole grain wheat down into porridge. It’s not the go-to use for wheat now, but the rice cooking method still provides a nutritious meal.
Started on Jeroba, but Thunder just felt more intuitive.
That is the fanciest ping pong paddle satchel I’ve ever seen! It’s also the first.








Excellent write up. Appreciate your time!
