I'm an idiot, so take my idea with a grain of salt, but I've played with magnets before and if you hold them in just the right position they will be forced away from each other.
Why not make a "road and floating car" where they have these opposing magnets that force the car to stay floating off of the ground? From there, propelling a floating car that isn't being affected by its own weight or friction. Hell, you could still even use wheels and it would be more efficient since most of the weight of the car would be nullified by the magnets pushing... Comment too long.

>>7637298 I've heard that fusion power could run on seawater, using heavy water as fuel. It would only create helium (a useful resource in itself), and could last for a very long time (thousands of years, I think; long enough to find a replacement or leave the planet). Is this reasonable, assuming we can get fusion to work, or is the an oversimplification?
>>7637314 That's the gist of it really - the main assumption there is that we can get a working commercial reactor at all. But if we can, it's effectively a renewable resource (I think that it's more than just thousands of years, but don't quote me on that).
1: Anyone here join Mensa, or a similar high IQ club? is it worth it? make good friends, or is it just an ego thing?
2: School was always easy for me, I didn't continue studying maths at uni, but I did some advanced stats (factor analysis, multilevel regression etc.) I noticed that in the last few years of high school a lot of people who were "good" at maths suddenly weren't; calculus, and higher level probability seemed somehow qualitatively different to the maths they did earlier. I am curious if anyone who studied maths further... Comment too long. Click here to view the full text.
>1.) Mensa is just a circle-jerking waste of time. If you have a high enough IQ (not equivalent to being smart), why would you waste your time with it? I think they do offer some scholarships and other small benefits for members though. If you have the time to kill and think you'll get in and enjoy it, go for it I guess. Just be prepared for the real life equivalent of /sci/ shitposters and popsci fans. And I'm not just mad and biased here. I don't know my IQ but it was high enough in grade school to be admitted to the gifted... Comment too long. Click here to view the full text.
Why does the wiki for photons say it has mass when photons are considered a massless particle. How could a particle without mass even exist in the first place? If photons truly are massless, then how can certain frequencies of photons interact with electrons in metal? How can photons from a heat lamp " generate " heat if they are massless? Something that travels at the speed of light cannot have mass, but something without mass cannot interact with something that does have mass right?
Neuroscientist here. I'm on my phone right now, so I'll keep it short. It has to do with their general wellbeing. A bunch of experiments on mice showed a lack of addiction when their environment was stimulating. Other mice developed addiction when confined to a cage lacking in stimulation. The same effect has been observed in humans, people develop addiction when they "need" the drug for stimulation. Obviously I missed a bunch of details here, but that's the general idea
I think they do sometimes. But seeing as it would be a serious liability the doctors must take steps to avoid it. Environment and the way a drug is administered could be important too. A person compartmentalizes things that happen in the hospital, you know? The habit of finding the drug yourself and injecting it yourself requires an almost seperate conditioning process.
>>7636900 I'll start off flat surface can only provide a perpendicular counter force right? second question is this picture, I'm supposed to find the angle of the bar at which this construction is in balance but I can't seem to find the right equations to do this
Could anybody explain to me why running up a hill is harder than running on level ground? I imagine it has something to do with overcoming gravity's pull? But gravity is present everywhere, yes? Is the steepness a factor?
>>7636582 You're increasing your potential energy, thus doing more work. In principle on a flat frictionless surface going round the Earth you would basically be able to keep moving forever once you started, moving uphill this is not so.
For science fiction writings, I want to accurately portray railguns and the math behind them. Could I get layman explanations of electrical terms and measurements? Volts, amps, joules, etc. Joules, if I understand correctly, are equivalent to kinetic energy, but everything else I don't understand at all.
>>7636532 Imagine that electricity is water or some other incompressible fluid, flowing down a pipe. The water molecules are actually electrons.
Voltage, measured in Volts, is the pressure in the pipe. The voltage difference between two points is a measure of how much energy it would take to move a charged object between those points - or how much energy would be released by letting it move the other way. (Moving an electron across a voltage of 1 Volt takes exactly one electron-Volt (eV) of energy, for instance).

Hello, i need your /g/elp. I'm looking for a logical circuit that follows the table from the image. 'I' stands for Input and 'O' for Output. The 2 botton rows are practically impossible. Thanks to all :D
