It's a common misconception that you'd need a "higher" dimension (four spatial dimensions) for a a 3D universe to "curve into". All you need is a universe that does not adhere to Euclidean rules of geometry, but is rather non-Euclidean. While non-Euclidean geometry is often modeled as a plane projected onto a surface of a sphere or other 3D object, that's not what is "really" happening. This is just a way for us to more easily visualize Non-Euclidean geometry. Here is an animation I did that gives a way to visualize the trampoline example in 3D: That being said, we do live in a 4D universe. Space-time is three spatial and one time dimension.

It does answer your question, depending upon what you define as human nature. If you take a newborn human baby and toss him into the wild, what will he become (aside from food for an animal) without other humans to teach him? That's what human nature is as I'm defining it. What we teach our children is what makes them civilized, and capable of social interaction. On the alternate end of the spectrum, we can also teach our children to be monsters via neglect and abuse. And to restate, I don't think human nature is in that respect is inherently good or bad. But being living creatures, we do have certain built-in survival instincts (what I define as our nature) that may not always produce good results in a group environment. That's where shame comes in. Over time, we've gotten better at producing a more civilized society as a result of it, and more enlightened philosophies emerging that changed the ideals of society. To wit, if no one was ashamed to own slaves, we'd still probably have slavery.

Here’s another that was hard programmed for improved experience many years ago: https://www.scienceforums.net/discover/15/

Which page, specifically? If it’s easier, you can just share the source material / citation the author used in support of this claim you say they made: … so that way I may review the original source material directly myself. “Go read this book” isn’t good enough here. Alternatively, perhaps we can BOTH save some time by acknowledging that this book you keep spam pimping across various posts maybe has nothing to do with the conversation we are having about whether human nature is good or bad. We can maybe acknowledge it’s unhelpful as a response to my question regarding how many positive examples it would take to change your mind and convince you you’re taking too grim a view by concluding human nature is fundamentally bad.

Maybe I misunderstood. I thought you offered to provide evidence your assertion was correct. It now seems you expect me to provide evidence regarding your assertion. Getting snippy with me just continues your downward slide all because of a simple request for further information. I hope you lose this chip on your shoulder before you are shown the exit.

Yes. I think that such demonstration, as well as visiting art exhibits, music concerts, ballet performances, travel to different countries, etc., broaden their horizons. I don't think that they specifically increase their interest in science.

And there's me thinking that his works were of great length! 🙂

Here’s a link I shared earlier in the other thread. It discusses possible biological and social influences https://en.m.wikipedia.org/wiki/Causes_of_gender_incongruence

As someone with extensive time in rural settings, I have encountered a fair number of people who still find the bolt action rifle quite sufficient. And would view the assault style AR15 as unsuitable for a sporting hunt. A well-aimed shot from Grandpa's rifle will bring down a mule deer more effectively than an AR15. The rifle will shoot more precisely and will usually have a round that works on larger game, like a 30-06, while the .223 round that most AR series weapons use is not as good. (though its report is fine for scaring off cougars) Most pests were scared off, in my and my wife's family history of ranching and farming, by banging kitchen pots together, which saves ammunition and decreases chances of a stray round sailing through your herd...or your neighbor's kitchen a half mile away. 😀 So the computer chip analogy might need work.

As your desire seems to be elevating negative views over positive examples, tell me how many positive examples it would take to convince you otherwise, specifically regarding the idea that human nature tends daily and in aggregate to be far more good than bad.

This little hospital has 16 rooms connected as shown in the picture. There is one patient in each room. The patients in the rooms 2 to 16 are bedridden, but the patient in room 1 is fine and ready to go home. This patient wants to meet every other patient once, and only once, and then to exit the hospital from the room 16, as shown. How can it be done?

Next time, explain that there are passive and active USB hubs. A passive USB hub may cause more power problems.. USB v2.x has max current 1 A, with 5 V, it is 5 W. USB v3.x has max current higher.. https://en.wikipedia.org/wiki/USB_3.0 With USB-C, it is even 3A. There are special USB multimeters: https://www.google.com/search?q=usb+multimeter which you connect to a USB port and connect another USB device to it. You can check how much current, voltage and power the USB device is consuming.

Hi! My name is Azzie, Im a writer and artist with a lifelong hyper-fixation on all things science! Funny how that didnt translate to career choices huh? Im always looking to expand my awareness and sharpen my knowledge and I hope to find that here. Even if I don't find that I certainly miss forums as a space, especially in the increasingly draining online spaces of today. ;~; Some of my other interests are: music, photography, folklore, channeling my inner rodent to collect shiny things, and cooking. (Im also very fond of animals)(*￣∇￣)ノ

There are USB ports v1.x. v2.x, v3.x, v4.x They have different maximum properties. You should ask the customer what kind of hardware they have (mobo model number, on Windows via remote RDP you can do that by using Start > dxdiag). Do they have USB v3.x or older v2.x (not likely v1.x, the hardware would have to be > 10 years old). Check out how they differ on Wikipedia's USB page: https://en.wikipedia.org/wiki/USB Passive and active hubs are available. A passive hub uses the power supplied by the computer. In this way, the maximum specifications are divided into several ports! An active hub can have an optional external power source connected. Each of them is very cheap: https://www.google.com/search?q=active+usb+hub (doubtful it is checkable by RDP) Connecting a power-hungry USB device to a passive USB hub with too many other devices will cause problems.. Especially power-hungry USB devices are: external HDD (old-style) drive (used as storage for backups, for example), and external CD/DVD drive (used by people who have no built-in CD/DVD - like my laptops over here) Laptop docking stations have extra USB ports. If the laptop is connected to the docking station, but the external power supply does not power the docking station, the USB ports may not receive enough power (everything goes directly from the mobo). If the software runs slowly, the hardware (processor and memory) may be insufficient. You can check what kind of processor the client has by using the previously mentioned dxdiag (on Windows). Then enter the processor model at https://www.cpubenchmark.net/ Compare dxdiag results with minimum software requirements. If the software is running slowly, the real-time CPU, disk and network usage when the client is using the software will give you an idea of the type of problem.

I'm not so lazy that I'd be opposed to starting a new topic on the subject either way 😀

Here's a start. When George awoke, he felt better than he had for days. The next thing that struck him was how quiet it was; the hospital had always been such a busy place. Now, the only thing he could hear was the oxygen concentrator humming away by his bedside. He remembered the doctor saying "With luck you might not need that tomorrow morning; you had a nasty brush with death , getting poisoned like that- but your lungs are healing well." He also remembered his wife telling the doctor that he had been a professional racing cyclist in Rwanda. - the jokes about why anyone would choose it and the answers; not much competition, and the natural "altitude training" you get from a country that starts at about 950 metres above sea level, and only goes up. The doctor asked if his genetics had helped. He wasn't sure if the guy know that his dad was from Bhutan and his mother Peruvian. He knew that without those lucky strikes, the chlorine leak at the swimming pool would have killed him, like it did all others there. The next thing he noticed was two flickering lights in his darkened hospital room. One was a "low oxygen" warning on the machine and the other was more threatening...

More specifically it is the nitrogen in the air. This is why to dive deeper, where there is greater pressure, special gas mixtures without nitrogen are used. Endy does have the right idea about expansion being the cause of the the trouble so to answer your query more fully, you need to know two things. As pressure increases more gas dissolves in a liquid (water, blood, cellular fluid etc). Dissolved gas is no longer a gas but part of the fluid. If the pressure is then reduced the additional dissolved gas returns to being a gas, as Endy says. All the fluids in you body have to be at the same pressure as the water at any particular depth or they would be squashed into a smaller space. This is not like a submarine where there is a rigid (metal) shell to resist the difference between the external water pressure and the air pressure inside the shell. So the air you breath when diving is at higher pressure than in the open atmosphere. So more of the gas dissolves in your blood stream. As you return towards the surface the pressure regulator in your air supply reduces the air pressure to match that of the surrounding water at your depth (obviously it also increases the air pressure as you dive deeper - this is all automatic) So on return some of the gas emerges in your bloodstream as bubbles, nitrogen being the particular problem. Your body can only clear these bubbles at a limited rate so if you ascend too fast they build up. The Bends occur when uncleared bubbles start to acumulate within the rest of the body, particularly around the joints in the skeleton. This is why you ascend slowly and in stages if you have dived to any significant depth. Does this help? Feel free to ask for amplification of any point.

At present, they are not but it isn't impossible to make transit systems self contained.

They might be more willing to listen to scientists, given that scientists created them. OTOH, there's also the nightmare scenario of Far Right coalitions that have AIs and feed them garbage data, the old GIGO problem. Or SkyNet scenarios, where the AIs develop very different priorities from human ones. A bit late to the party here, so I'll spare you my usual rant against profit-centered medicine. Others have pointed this out, and the gory details covered nicely. I continue to devour vegetables and walk miles every day, in hopes of depriving our healthcare system the pleasure of sinking its poisoned talons into me. Cheers.

There is something more, though. One party and their news sources actively pushed back against the science of masking and immunization. Some still are. Those folks died and suffered in far higher numbers. And due to reasons of fragile ego and selfishness / inability to concern oneself with others, Trump was kind enough to take it one farther and spread the virus to the key leaders in his administration and everyone at Justice Amy C Barrett’s coronation ceremony. Last study I saw said almost 900,000 lives saved by masks and something like 2M more which could’ve been saved were it not for that desire to willfully spread ignorance and disinform people as another tribal wedge strategy. It’s not like humans were totally powerless to change the spread. We just concerned ourselves more with hollow notions of freedom than we did with the ability of our neighbors to continue living and how massive a role we each as individuals play in that as a society together. The funny part is that a real capitalist would realize government funded universal healthcare is both cheaper AND more effective than the disgusting grifter filled sludge of a healthcare system the US has today.

We also can’t spend time shopping around for which providers offers the lowest cost and best care after having a heart attack or getting hit by a bus. “Sorry, Ambulance Driver. I know we’re sort of in a hurry here, but let me first please check the ratings of the 27% of doctors nearby who actually accept my brand of insurance as a valid form of payment. I’ll tell you which one to drive me to here momentarily so long as I don’t bleed out first.” Several steps away and there’s neither ladder nor staircase nearby to climb. That’s not a market. That’s a sham.

Why? Autonomous mass transit is perfectly feasible. The autonomous trucks don't need any more roads; there are way too many roads already. Of course I know what you're fretting about. You think the only way to be free is the Davy Crockett way. Well, he was an ass. Having a constitution ought to mean that laws are based on the welfare of the entire polity, not that some people run off with a fragment of text and do whatever the hell thy like, because they have a powerful lobby and craven, corrupt politicians. if I'm emotional, it's about people exercising their gun rights school-children. I have no designs on their doors, nor on their houses, or whatever other property you're worried about. Just the guns. That's not negotiable. And be warned: I'll be demilitarizing the police next. Yep. Pretty soon, I'll demand to see those kids who have not been gunned down in their classroom properly fed and given adequate medical care, even if their parents are poor. Catastrophe is sure to follow. He's an ass, too.

Oh Word! Good to know. Now if I can build a better reputation I'll be alright. haha

Hardly. These observations have been standard stuff for most of my lifetime (I'm 68). That's why you find the better run economies in Europe tend to practice a form of mixed economy, sometimes referred to as social democracy. In short, people have learnt what to take from the ideals of socialism and blend those with regulated market economic mechanisms to get the necessary feedback from consumer to producer. What has become equally clear over the last couple of decades is that inadequately regulated market mechanisms can also fail to deliver for citizens. The water and railway companies in Britain are examples, as is the health system in the USA. What we are also now seeing, with the new transnational IT entities such as Amazon, or Zuckerberg's empire, is that it is becoming a struggle to prevent the development of international monopolies which hand an unacceptable degree of control to producers, while disempowering consumers, just as much as any state-planned enterprise in the old USSR. It seems to me issues like these are the real food for thought nowadays.

I suspect distaste for homosexuality is inborn in many of us. Given that we have a drive to be attracted to the opposite sex, we find the idea of sex with someone of the same sex a big turn-off. Consequently we may find the idea of a sexual approach from somebody of our own sex rather disturbing. If that is homophobia, then I am a homophobe. It seems to me that the blanket term "homophobia" is thrown around too easily. One needs to draw a distinction between personal sexual taste and the attempts by some to condemn different (minority) tastes in others. It is the latter that society should refrain from.

LIGO detects gravitational waves, since 2016. Gravitational waves are very low frequencies < 7000 Hz, well below the visible range. Thus the waves are detectable while the black hole is not visible. The statement ‘even light can’t escape’ is referring to the range detectable by humans. Pound-Rebka did an experiment demonstrating light (em radiation) gains energy moving in the direction of a g-field, and loses energy moving in the opposite direction. This is in agreement with gravitational red shift.

! Moderator Note Then find the material and link to it. This is unacceptable in a scientific discussion. ! Moderator Note This and the first statement are also unacceptable Rule 2.12 We expect arguments to be made in good faith. Honest discussions, backed up by evidence when necessary. Example of tactics that are not in good faith include misrepresentation, arguments based on distraction, attempts to omit or ignore information, advancing an ideology or agenda at the expense of the science being discussed, general appeals to science being flawed or dogmatic, conspiracies, and trolling. Specifically, a claim that you can make the models say anything, and that NASA/GISS are manipulating data. You want to believe this things? That's your business. But you don't get to claim that here without having the receipts.

Any thoughts about the rest of what I wrote, or do you prefer to be pedantic?

He wasn't questioning the specific experiment; if he was, he did so poorly by his choice of text to quote. In any case, his follow-up indicated, he questioned that science experiments at all would get kids "interested". All this because of a faulty, and utterly ridiculous inference that I meant every child would be interested in science as a result of observing science experiments. A difference without a distinction, sir. That's one opinion, but in the real world we teach children things that are grossly oversimplified all the time, just to instill a basic understanding of a topic. Just how accurate do you think elementary school history lessons are, exactly?

So, just let men play the women, so long as they claim female gender? There's a lot of money at stake, it would be well worth it. Wimbledon, US open, women's events won by second grade men claiming female gender? I don't think it would go down too well.

On an individual basis, perhaps not. In the aggregate, some kids are going to find science experiments pretty cool, and want to learn more. If that’s something you can’t agree with, clearly you don’t know many kids.

Did you read his post? He's asking for evidence to support a pretty easy to read statement that anyone with a basic grasp of the English language can understand. That's being deliberately obtuse, and if that's the kind of behavior you wish to defend as a moderator, I'm done here.

Are you seriously demanding evidence that performing science demonstrations / experiments for kids will tend to increase their interest in science? Buzz off. Thanks for the thought!
