Is he right /sci/?
>tfw no aliens after all
All the sensible people already knew there were no ayylmaos in KIC. its just the /x/tards around posted pop-sci links that try so hard to make it look like aliens with zero scientific reasoning.

Hey /sci/ I honesty have a legit question. It might have a simple answer, but anyhow.
>what space, does the Universe occupy? You could answer with space, but the next question would be.
But that would lead to more questions!
>>7792906
Theres no way of knowing if the universe occupies any space. Your question is based on an unproven assumption
there are no types of space retard. theres just THE space that the universe sits in.
>>7792907
Anon I was just thinking, I wasn't trying to make assumptions. That's why I'm asking you guys.
It's just mind blowing to think that the "universe" or infinity, was somehow contained inside space!
What would happen if an organization put something into LEO in the ionosphere and keep it in geosynchronous orbit with a receiver to beam a laser to the location for wireless power transmission? Could an optical tether be built between the two that would allow for high-efficiency energy transfer?
The energy it would be capable of producing would rely on its surface area relative to its tangential velocity. Cost would be whatever unit of cabling versus budget of making it micrometeor resistant.
So wait, when hydrogen fuses to form helium, where do the neutrons come from?
>>7792682
My ass
>>7792682
Does the energy released from the fusion create the neutrons?
>>7792695
don't you mean absorbed? how would it form from energy being released?
how does an electron avoid colliding with the proton given they're opposite charges? this is my current understanding. sorry for the bad handwriting, and knowledge, and understanding. i'm so sorry.

https://en.m.wikipedia.org/wiki/Uncertainty_principle
I'm not a physics major but it seems that it's because of the uncertainty principle.
The product of the standard deviations of position and momentum are greater than or equal to h bar over 2. So the more precise you know the location the less precise you know the momentum. If the electron was in the proton it would have 0 momentum and you would know its position, this is impossible.
It's to do with the wave nature of matter, something about the position and momentum are fourier transforms of each other so this causes the inequality
>>7792698
so it has nothing to do with potential gaps or the pauli exclusion principle? damn i was far off.
it makes sense though, i was aware that position and momentum can't be measured without influencing one another, but i didn't know fourier transforms actually came into play. that's pretty damn fascinating.

The universe doesn't give a fuck about what some mouthbreathing monkey shits know, fuck you and your shitty fucking principle.

Underrated and obscured by corporatism or overrated by fan boys?
What is up with teslas death ray? That shit is cool, i wish it was real.
>>7792035
>obscured by corporatism
He's not obscure though. There's an SI unit named for him and he's huge in popular culture. He didn't get rich and famous like Edison, but there's only a handful of scientists and engineers who get that kind of success.
There's also over-inflation of his accomplishments. He did not invent DC power. DC power grids existed before he was even born.
>>7792051
Do you think he was smarter than Edison?
Is silicon-based life a legit possibility?
pic unrelated
>>7790908
Not really, silicon ionizes too easily to maintain large covalent systems.
Organic (carbon) chemistry is extremely diverse. Silicon is tetravalent like carbon but doesn't produce such rich chemistry, as far as we know. This limits the complexity of any life-form expected to emerge from silicon chemistry. It might also limit the means by which chemical automata could form under moderate conditions, or abiogenesis.
The Milky Way is about 4600 ppm carbon and 650 ppm silicon, so carbon also wins in abundance. I suppose it's unlikely that the silicon fraction would often be concentrated either.
Probably possible, but unlikely and limited.
Silicon isn't anywhere near as compound-forming like Carbon is. It's been noted that over 90% of the compounds you commonly run across as a living organism, contain Carbon. Carbon's versatility in forming compounds makes it a primary organic element. Combined with Hydrogen, Oxygen and Nitrogen, you end up with a CHON biosphere, probably in all instances where biospheres form.
How clinically-useful is the rectal exam in asymptomatic patients, or as a regular screening tool? The guidelines keep reducing its recommended usage. Have doctors been needlessly fingering people's asses for decades?

>How clinically-useful is the rectal exam in asymptomatic patients
Quite small in asymptomatic younger patients.
In older patients ~50% of rectal cancers can be palpated. Also prostate cancers can be palpated.

Is there a generic formula for performing a modulus operation on a number that is in base 'n'? If not, what's the best way of performing a modulus on a very large number that is not in base 10?

if its negative, times by -1

Yes (https://en.wikipedia.org/wiki/Nuclear_power).
In fact, it has been shown that background levels of radiation are lower around nuclear power plants than elsewhere.

Mods are napping. Post algorithms you've programmed.
More languages the better.
Why would the mods care about algorithms?
Starting off very simple, GCD of two numbers.
Euclid method.
Math enthusiasts welcome, post some hardcore algorithms.
Programming enthusiasts welcome, post some hardcore algorithmic code.
Still keeping it simple, square root function, more python jargon however.
Newtonian method if I'm not mistaken.
The conditional statements [if statements] are there just for error handling, and do not really play a part into the algorithm.
Three things appear to exist: Location, directionality, and speed. Relative motion necessitates the existence of an absolute.
Humans are machines. Inside each of us various particles are moving around, changing their arrangement, being gained, lost. We're on a planet. That planet is rotating. It's also revolving around the sun. The sun and our solar system is being pulled around by nearby systems, which are all moving within the gravity well of the supermassive black hole at the center of the galaxy. The galaxy as a whole is being pulled around by other galaxies. Etc.
Given a means, I can move around. I am not everywhere, therefore, I can change the "somewhere" that I'm presently occupying. However, given all of the above, if I move even a few feet where am I really moving? What is my actual motion through space when tethered to something that itself is undergoing such a large amount of motion? What is my absolute location and how is it changing? This would require a perspective that encompasses the whole of all things, but clearly, an absolute must exist.
Therefore, somewhere, there might be a stationary object. An object that is not moving in any regard. Unlike all else, it is stationary. Only by knowing and being everything could you realize it's you who's moving, and not this object. The universe is probably binary. Either something is or is not moving. If it is moving, "speed" is actually a localized distortion of time. Distance isn't actually contracting, the object moving is subject to fewer ticks per any given interval, so as far as it can be aware, distances are shorter. The stationary object would exist in realtime, and would be undergoing the most rapid change.
I like this idea, but all forces act on both sides, hence making an unmoving object impossible since it would be influenced through the stuff it is influencing
>>7777872
It would need to be in some sort of system that nets out into an equilibrium state, even if only briefly.
the stationary object you're looking for is called the observer.
how do jellyfish live
they have good life and less depression than the average humen i think
they're an amalgamation of a simplified peripheral nervous system with no sign of central cognition or spinal relaying. they have asexual reproductive cycles and are able to fend off adverse aging effects via some sort of DNA enzyme they can produce but we can't which allows for higher amount mitosis before corrupted RNA is displayed. they also have an efficient metabolism given their ambient body temperature regulated in the water with high level of consistency, and have good defense measures with their small hooks which can inject strong neuropathic compounds into its prey or predator, rendering them immobile.
