If smoking is really that bad for you, why is it that despite the nearly 9 decades of anti-tobacco research and the government's non-stop assault on the users, not a single scientist has been able to prove that tobacco causes cancer or COPD in even a single animal or randomized epidemiological study, thus forcing the entire consensus to rely on self-selected epidemiological data without controls for extraneous factors (and even then of course the evidence is weak at best, compare Japanese or Greek lung cancer or COPD rates to the very anti-smoking USA). Curious thing.

Hey eggheads, how much energy would it take to keep artificial beach like this warm and bright in polar night in, let's say, Antarctic region?

>> No.10392062

At least as much as the equivalent black body radiation for the temperature/surface, increased by a factor depending on quality of insulation.
At 300K black body radiation is about 500W/m^2.

Would be better to built it in space: good insulation and facing the sun you could get it as warm as you needed.

The entire reason why 4chan is unique to discussing with intelligent people IRL is the anonymous nature. It means you don't have to take ego into consideration or be worried about what the other person thinks about you and therefor your arguments can include a lot of topics and depth that they wouldn't be able to IRL.

Try discussing the difference in neuron count in mammals between female and males of their species and it would be a very awkward discussion due to all kinds of assumptions and implications.

Have that discussion on something like /sci/ and as long as you ignore poltards it can actually be interesting. That's just one example of course.

Why are the chimpanzees and bonobos considered different species?

and am I on the correct board[/spoilers]

>> No.10391962

Because you touch yourself at night.

>> No.10391995

Before the 1930s, bonobos were considered a subspecies of chimp as well and were called pygmy chimps, but researchers decided based on physical differences that these smaller apes are distinctive enough to warrant separate species status.

>> No.10392021

Species are mostly a subjective concept. For example polar bears and brown bears can produce fertile completely healthy offspring yet we consider these to be completely separate species.

Same with humanity. We aren't even a real singular species but a hybrid species of homo sapiens+neandethals+denisovans+erectus and a lot of other unproven ones. Races are determined by the mixture of these homo genes.

I had a lot of problems coming to terms with this when I was younger. But the earlier you start to understand that it's just purely subjective labels and not really based on a stable definition the easier it'll be for you.

Bonobos and Chimpanzees are largely the same species but we have subjectively decided to make them different. Neaderthals, Erectus and denisovans never went extinct but instead created a singular mixed species we now know as humans. We aren't homo sapiens unless you are a pureblood aboriginal.

If you have the tool that recognizes fakery, you could build a bot that can fool the tool.
An easy way to hide tampering is to save the edited image at a lower resolution/quality.

You still need to have the skills to make a fake that respects the light source.
If the light sources don't appear to come from the same place or have the same color, it won't look real.

An interesting idea for phone camera makers would be to implement some sort of steganography that encodes information in the least significant bit of each pixel.
They could hide metadata that would tell them device, owner, time of picture, gps location, short audio clip at the time of picture, etc. along with a hash value that would detect tampering.

it literally isn't. There are cameras that have a very specific sensor pattern which, if the output image is disrupted by tampering, can be easily used to reveal a fake. And even without any knowledge of camera intrinsics, you can make use of basic geometry of lights and shadows as
>>10391838
mentioned. For example, the line from every identifiable point to the shadow it casts must converge on the same vanishing point if it's illuminated by a parallel light source like the sun.

It was supposed to be viable here, all you'd really have to do is connect two densely populated zones (or even semi-sparse zones like suburbs to the main cities). The best place for this was California, but corruption, lawsuits, and good old fashioned "good enough for government" work killed it. They really should have just connected San Francisco and Sacramento or San Francisco and somewhere halfway to LA as the first stretch; not that retarded route they decided on in the Central Valley. That alone would have alleviated some of the problems of urban sprawl and high cost of living in the area. But no, we can't have that here. Did you know that we got offers from European and Japanese railways to help, but they got turned down because of laws requiring a certain percentage of American contracts? There was even a private funding plan from a French company.

I don't really give a shit anymore, let people be retarded. It's all going to burn down and I'm just going to spend my money preparing and enjoying my muscle cars. Either people get fed up and push hard enough to clear the corruption or we slowly decay further into a backwater where every project just serves to bloat some political donor's wallet.

OK good. you sound knowledgeable.

Spark/Ark/recombination. If it would be enough to ignite a CH4 gas leak then that is a problem.

I'm not sure what you mean. Keep in mind a 9 volt battery can drive a 100,000 volt stun gun. So yes even small voltages stepped up can create an arc big enough to cause an explosion. Very low voltages are unlikely to do it. Every gas has their own particular break down voltage, but it doesn't take much for methane (CH4)and O2 to go.

>> No.10391822

>>10391805
yes a stun gun powers a 9 V battery coz it steps it up. You could power a stun gun with enough pieces of copper, zinc and lemons.

What I mean is, if someone said
"I'll pay you $1M to stand in this chamber filled with CH4 and air at a correct flammability mixture (you can have your own independent breathing supply) and then short out a 12V battery with a spanner, would you do it? How confident the air/CH4 wouldnt explode from the sparks caused when you short the car battery.

Now, same question but make the battery 6V

Same again, make the battery 3V, 2V, or 1V

At what voltage would there definately not be a spark capable of ingiting the mixture??!?!?!?
