What is /sci/s opinions on flying cars? I think it's a good idea because driving across a major city takes like an hour when it's just 20 miles which you could have flown in 10 minutes. If I had a flying car I could have applied to more universities than one. Also in places like the Amazon where there are no roads your choice is a week of battling through mud and crocodiles or a £300,000 helicopter and the £30 an hour pilot to fly it. Imagine if you could just hop into a £10,000 flying car and have it fly itself to your destination?

I mean, there's a lot less to crash into in the sky.

That is, of course, until it's filled with idiots flying in cars.

As I see it the hardest thing would be not being able to restrict people's movement in the way roads do, leading to a potential shitfest and danger for all.

How come eugenics didn't work out?
As far as I know it has been practiced earlier and way more intensely in the United States than in Nazi Germany, yet (no offense) Americans don't seem that much smarter or overall more superior. And in case someone will come with the argument that minorities are driving down the average scores of the country, even if you single out white Americans they aren't really that smart alone either. European countries where eugenics haven't been practiced like Finland, Netherlands or Switzerland have a higher average IQ than the US.
Yet again, no offence.

Aha.. This has nothing to do with eugenics
>>
>>8121476
beat me to it.

Although this meeting isn't about eugenics, it's only a matter of time before we start up on eugenics programs again. Unfortunately, thanks to Hitler's stupidity, he set back projects like these lots of years back for the West. The Chinese will make it first.

The reason eugenics didn't work out is because crossing smart people doesn't guarantee the offspring will be smart, because of variation, and because of nurture. IQ is malleable, and the way someone grows up greatly affects how you score.

Remember me /sci/? I said that I did some undergraduate research in my own time but I threw an autistic fit because the professors weren't interested at all so I got disillusioned and quit pure science. I know now that my tantrum was wrong however /sci said I never came up with anything because I was just a first year student and I couldn't even give the derivation which I claimed was due to me throwing away the document.

Microsoft has decided to keep my deleted documents in the cloud against my will so consequently I just found it by chance now while trying to email somebody something. Here's page 12 matching it to experimental values

Look, I'm not trying to prove anything, I've just always wanted to know if it was bullshit or if there was something to it. My beef with the professors wasn't that they dismissed it, it was that they never even looked at it so I don't know if they would have dismissed it or not. It's basically Heim Theory; derivations appear to be total bullshit yet oddly it gets the right answers. Now with Heim Theory what happened was that he encoded the empirical constants in from the beginning which is why the equations reduced to it and people thought anti-gravity was real. Maybe I did something similar? I dunno I hope /sci/ can do what it does best by ripping it apart so I finally know.

If enough people are interested I'll post the rest of it.

In short it's an equation of state.
https://en.wikipedia.org/wiki/Equation_of_state

It can predict a range of gas characteristics such as:

Critical temperature
https://en.wikipedia.org/wiki/Critical_point_(thermodynamics)

and Boyle temperature
https://en.wikipedia.org/wiki/Boyle_temperature

from only one experimental value (the intermolecular potential energy well depth). In comparison all other equations of state such as the Van der Waals Equation
https://en.wikipedia.org/wiki/Van_der_Waals_equation
need at least three variables and are still less accurate. I don't really know why my equation works though and no-one has ever offered to analyze it.

No. This evolution stuff is bullshit. Not even 6 billion years would be a long enough time line for creatures to evolve to where they are today

According to what? Can you not grasp how long 6 billion years is?
>>
>>8123023

It's not /even/ 6 billion years. Life didn't start on this planet until billions of years after it was created.

And no, it's still not long enough for all these random "microevolution" mutations to add up. It's highly improbable.

Is this even controversial?

If a mad scientist injected you with nanomachines that slowly, in real time, destroyed your brain cells and replaced them with mechanical duplicates, then there would never be a point where you could be said to suddenly stop being conscious.

I've got a question /sci/

First time visiter here and I assumed this is the best place to ask.

Is there any connection or relation between Absolute Zero and the Speed of Light?

My reasoning is movement is in a way, heat.
Yet at absolute zero, this is when things stop moving entirely if we could reach it.

So if absolute zero is when movement stops and the speed of light is the fastest that movement can go, is there a connection? I came to this question when thinking about the idea of an "absolute hot"

Not that we know of.

For more information get a PhD in Theoretical Physics.
>>
I think Kelvin just extrapolated the ideal gas law back to where pressure is zero to determine absolute zero (originally). Not sure how this would relate to the speed of light though.
>>
>>8124709
kind of like asking whether there is a connection between light and shadow.

One is the absence of the other. Absolute zero is the absence of (heat) energy

We still don't know much about evolution. Most of it remains hypothetical / speculative, mostly due to the fact that macroevolution cannot be reproduced in experiments.

Mendelian genetics, Discovery of DNA etc...
>>
>>8121463
Where to start?

We discovered how inheritance actually works (Mendel).

We developed mathematical/statistical models how inheritance and evolution interact (Fisher et al).

We discovered the biochemical mechanics of inheritance and how it interacts with the cellular workings (all the stuff in the wake of Watson/Cricks’s discovery of DNA).

We learned that DNA isn’t so much a blue-print but some kind of baking recipe, and that the constraints of development of a fertilized egg put restraints on evolution (the whole new field of Evo-Devo).

We discovered that lateral gene transfer is surprisingly common.

We learned more about the importance of neutral genetic drift.

We learned much more about the actual natural history of evolution, both due to immensely more fossils and genetic comparisons.

And we now have some preliminary ideas why sex might exist.

How is it possible for the galaxies in the front of the picture to seem so close to each other when in reality the distance between galaxies can be 10x or even 100x a galaxy's size.
