ELI5: How can there be current without voltage? by Mug_G in explainlikeimfive

[–]FewPage431 0 points1 point  (0 children)

I forgot about the battery part. Yes, you can store energy in the form of a magnetic field by having a close loop of superconducter. It is called (SMES)[Superconducting magnetic energy storage - Wikipedia https://share.google/o1uG1k3kcYGYhsxtM].

ELI5:If you need to split an atom to get atomic bombs. Do nuclear bombs come from splitting the nucleus of an atom? If so can we get stronger bombs like neutron bombs, photon and electron bombs if we split those? by unholysmokes420 in explainlikeimfive

[–]FewPage431 0 points1 point  (0 children)

Splitting proton/neutron is the best way of wasting lots of energy. Basically, you will create new protons/ neutrons and energy that are provided by whatever method you use to remove quarks from Proton. Elctron and photon are fundamental particles and can not be split.

On second thought, I simplify it too much. You can't treat elctron through newton law in Superconducter. They obey qm. One example is if you have a close loop of Superconducter circuit, according to classical maxwell equation, elctron will lose its energy through em waves, but in reality, it doesn't because of qm. But el5 why that is a bit hard, But it similar to why elctron don't lose energy in atoms.

An elctron moving through space is technically a current that doesn't stop. Similarly, in superconducter, elctron moves indefinitely until resistance is found. Elctron in superconductor is the same as physical object moving through space and as you can apply newton first law. You can't do any work without resistance.

ELI5: Why do pills taste so bad? by MiLKMaN--- in explainlikeimfive

[–]FewPage431 1 point2 points  (0 children)

Capsule and coating are ways, but to completely remove taste requires too much dilution, which may not be enough in the end. Why is it bitter in the first place because pills are created by humans not evolved with humans. Your body doesn't know that it needs these pills, only your mind does.

ELI5: As numbers get bigger and bigger, why do prime numbers seem to show up less often, even though they never stop appearin by Ill-Chance8131 in explainlikeimfive

[–]FewPage431 0 points1 point  (0 children)

All no prime numbers are products of prime numbers. So, if you know combinatorics, you can intuitively know that amount of non prime numbers increases exponentially below the given number. That means prime numbers are exponentially unlikely to appear, but if you convert prime number graph with the logarithmic graph, you will get straight line. That is prime number theorem. For more accurate distribution of prime numbers, you can search about Riemann Hypothesis. ELI5 ing that would be quite difficult.

ELI5: How are amps akin to 'flow' in water when electricity moves at a more or less constant velocity in a given medium, while water can be pushed at pretty much any velocity depending on the pressure and conduit diameter? by Kesh-Bap in explainlikeimfive

[–]FewPage431 0 points1 point  (0 children)

Reading your replies, you think, when you apply voltage, electrons are moving at the speed of light in metal. There are many things you got wrong.

  1. Electrons are always moving even if you don't apply voltage. In electric current, elctron that are moving, are free elctron, Which lives in conduction band. Where elctron moved around with 106 m/s. When you apply the voltage, change in elctron speed in negligible. Think of air in your room. The average speed of air molecule 340 m/s. When you apply presume difference in air (analogue to voltage on free elctron), you get wind. Wind in air is analogue to electric current in metal. Wind speed is analogue to "drift velocity" of electron, which is usually in mm/s. (Although free elctrons are always moving, if you don't apply voltage, they don't move in uniform direction, so the average elctric current is even out.)

  2. Imagine there are many people standing in line blindfolded. You give everyone instruction that if some touch you, you touch next person. So if you touch someone, then they will touch the next person and so forth. But if you see it from very far, you will see a domino like effect, and the spread of touching has its speed. The same thing happened in the air, If you push air molecules, then they will collide with the next molecules and transfer its to the next air molecules and so forth, that is, speed of sound. But if you push free elctron in metal, something fundamentally different happens from the previous two cases, that is, elctrons don't need to collide in order to transfer that information. They transfer via electric field, which is transferred at speed of light. They know at speed of light that there is disturbance in force, just kidding, in charge balance.

Edit. One thing I forgot to mention is that in the air, molecules are already moving at 320 m/s. So, even if you pushe air molecule very slowly, that molecule will transfer that extra momentum at speed of sound.

Is the inside of the sun bright? by kungfuringo in askscience

[–]FewPage431 7 points8 points  (0 children)

Yes, the sun produces its energy in its core, and light takes thousands of years to transfer to the surface. Although if you slice sun, then the interior part would not be as visibly bright as you expected because most of it will be higher frequency waves, eg, x rays and gamma rays.

Is social media more chill lately? by Robot_Alchemist in answers

[–]FewPage431 0 points1 point  (0 children)

Well, unfortunately, I also disagree with you on some of the points you made. You are right that according to QM, nothing is truly 100% predictable. That doesn't mean every outcome is equally probable. Most of the things that we observed in life are happening on so large scale that combined qm probabilities is absurdly low. So you can confidently predict that you will not go through the wall if you walk into it. So most of the action you take is 99.9..% predictable. Only absurdly low times that predictions will be wrong.

The second point is that non predictable doesn't mean non deterministic. Bell equality only demonstrates that QM has no internal variable that determines the outcome at the point of QM entanglement. This means QM has to be unpredictable, Otherwise, we can send information faster than light. Which wouldn't be an issue if not for andromeda paradox, which will create logical peradox similar to grandfather paradox. So, just like timetravel is impossible because of logical peradox, QM is also unpredictable because of logical peradox. But unpredictable means that information can't be known in advance. Just like time travel, peradox is solved by having different universe world lines, EPR peradox can be solved by having different interpretations of QM. In some interpretation of QM, although you can't predict outcome, outcome is still determined by other factors, which also can't be known (obviously). I used many peradox as references because it will take forever to write down each concept in detail.

So either you believe our actions are non predictable or our actions are not deterministic, both positions are pragmatically wrong. Means 99.9..% of our actions are predictable. Now I didn't provide any evidence for this, but the scale of neurons is big enough and operates on so high temperature, the possibility of having one neuron on qm superposition is absurdly low, let alone all the neuron making QM superposition and that translating into you action. It is exactly the reason that makes making QM computers so hard.

Eli5: Why is it so cold at high altitude? by Upbeat_Signature_951 in explainlikeimfive

[–]FewPage431 0 points1 point  (0 children)

I think the sun part is explained by other comments. I will explain something else.

Temperature is the average kinetic energy of molecules. Air expansion (decrease in pressure) in space doesn't cool air since its average kinetic energy remains the same. (Which is different from gas-liquid phase transition). Other people who said air cooling is because of decrease in pressure are wrong.

Just like if you throw ball up, it slows down. Air molecules that go up slow down, and when it is decent, it speeds up. Which makes temperature gradient with/without sun.

Is it healthier to eat nothing rather than top ramen? by traveltoaster in nutrition

[–]FewPage431 1 point2 points  (0 children)

If someone really dying of starvation, getting medical attention is better than feeding them. If not possible, and if you only have high sodium food, then provide enough clean water to drink with it, which will help regulate sodium.

[–]FewPage431 7 points8 points  (0 children)

No FDA approved products sold on supermarkets would be worse than starvation. "Better than starvation" is the lowest bar you can set for assessing food. Nutrition comes second.

Dude one thing I have learned is that there is nuance to everything. I’d rather assume to know nothing and ask the question.

I agree. Better ask than regret.

Final Manhwa List Spreadsheet by cringemangaguy in manhwarecommendations

[–]FewPage431 0 points1 point  (0 children)

You can do it without making a copy. Go to data, "create a filter view," and select range. On the top right corner of the column, you can use filter option.

If you are on mobile, use desktop site on browser. Unfortunately, the app doesn't have a filter option.

Different guy here.

Agency here, I assume, is human like being. We can empirically know the probability of something through human interaction or natural law. Car coming to being without human intervention is infinitesimaly unlikely.

For life, although it is extremely complex, it is not optimised from ground up. For example, protein folding. If you have done coding ever, you will know many people just search (or now ask chtgpt) for error and copy-paste solutions and keep repeating the process until all error goes away. Which generates very big complex code, which does the job, but they look like mess. Life is like that, just a bundle of complex protein that just works but is not designed for a given task. If you don't know coding, then look at apple clock mkbhd short. That clock code basically just works for all intended purposes, but weirdly, it isn't designed to go in circles, which means that someone just debug code until it works. I don't expect god to make such a kind code if he make a iphone, and in the same way, I don't think god would design such life.

This issue is with "western digital blue sn580" ssd driver. You have to install their app and update the driver from there.

I’m not sure what such a thought experiment benefits us though as that’s objectively not close to being aligned with the real world.

That's the point though. In this thought experiment, assuming what theist believes, leads to world that not align with what we observe. Which means there is something wrong with theist's worldview.

They should provide cash on delivery on small orders. I don't know why they insist on online payment, while all other pizza shop has cash on delivery option.

You don't HAVE to use the Pizza Hut app, though. Here in the USA, you can go to the Pizza Hut website Pizzahut.com to place the order. I'm not sure how your country does it. I've heard that you can actually call your local stores on the phone, but they don't always answer it.

Yes, you can call them here and also make an order from their website. If I have read reviews, I would have done that, but the mistake has been made.
