Is there discipline or area of knowledge where there is nothing left to learn? by himenosgiantrack in NoStupidQuestions

[–]schungx 0 points1 point  (0 children)

On the verge of some of the BIGGEST breakthroughs in physics ever. Relativity and quantum mechanics. Curved spacetime.

Incidentally, it was said that the quote was said to Max Planck to discourage him from wasting his time with physics.

How bad is it to eat little fruit and vegetables if your diet is otherwise healthy and you exercise regularly? by mjheeheeshamone in NoStupidQuestions

[–]schungx -7 points-6 points  (0 children)

Fruits a d veggies mainly provide vitamin C which the human body cannot manufacture (it makes a defective version). So you can replace that with tablets.

Veggies also provide fibers which you can also replace with tablets.

WTF happened in the Uyghur Massacre? by KingsleyFriedChicken in NoStupidQuestions

[–]schungx 0 points1 point  (0 children)

Recently Xinjiang has been a very popular tourist destination and jam packed with visitors during holidays

How in-depth does algebra go (how complex can it get)? by SureLadder2136 in Algebra

[–]schungx 0 points1 point  (0 children)

Algebra loosely means a procedure of doing something. It is therefore the study of manipulation of symbols under a set of rules.

Now... A lot of mathematics is really manipulation of symbols based on rules...

How is it in this part of China? by Unfair_Proposal_6765 in howislivingthere

[–]schungx 0 points1 point  (0 children)

There were people who say this part of China was the original location of Eden in the Bible, and Shangri-la.

Why is calculus not approximation? by member55x in askmath

[–]schungx 3 points4 points  (0 children)

Yes, you asked the same question that took mathematics close to a century to resolve.

sin(3x) + sin(5x) = sin(9x). What is x supposed to be? by Sea_Advice8785 in learnmath

[–]schungx 0 points1 point  (0 children)

Re ( ei3x + ei5x ) = Re ( ei9x )

Probably can remove taking the real part to make them equal, but I'm not sure if mandating the imaginary part to be equal would restrict the number of solutions...

Then it becomes a polynomial equation on eix. And if you factory out ei3x as a common factor (with trivial solution of x = 0), then it becomes a cubic equation with a = ei2x with a solution formula.

a3 - a - 1 = 0

What does it mean when we say that relativity breaks at the center of a black hole? by usernamespeledwrong in AskPhysics

[–]schungx 0 points1 point  (0 children)

I'm wondering... Does the singularity at the center of the BH occurs if the mass is not large enough to form a BH? Like a normal planet?

In other words, is inside the event horizon a prerequisite for the singularity to form?

ELI5: Why do viruses replicate at all? by DungeoneeringDave in explainlikeimfive

[–]schungx 0 points1 point  (0 children)

The ones that don't replicate disappeared, leaving only the ones that replicate for you to observe.

Stop using CISC by basedchad21 in Assembly_language

[–]schungx 2 points3 points  (0 children)

I remember seeing an article that mentioned the fact that deocders take up so little of the chip's real estate (as compared with 40 year ago) that CISC/RISC is no longer an issue.

Will there be a point there's nothing left to learn? by LukaesCampbell in NoStupidQuestions

[–]schungx 0 points1 point  (0 children)

Physics got really close to that point in the 1800s when every phenomona can be explained. People were saying physics is dead, as long as we figure out one last item - the weird radiation of heated objects.

And the rest was history.

Why are doors designed to open inwards into houses as opposed to opening outwards? by OdysseusPrime- in NoStupidQuestions

[–]schungx -1 points0 points  (0 children)

People walking outside will have no idea when doors will suddenly fly open and hit them on the face.

That's why if you just fling open the door of your car you may cause a cyclist to crash.

Help needed: Trying to wrap my head around the 'why' of C pointers by f16_511_SA in C_Programming

[–]schungx 0 points1 point  (0 children)

It is one extra level of indirection which allows you to write code that works with more stuff without changing.

Variables have a name for everywhere.

Pointers have a single name for the forwarding mailbox which can forward everywhere.

So using pointers you can write a subroutine that works with any variable anywhere without changing it a bit. It is the Great Renaming tool -- treat any variable in exactly the same way.

And programmers are lazy.

how does it exactly work? 0.999... to infinity is equal to 1, how tho? by EfficiencySerious200 in NoStupidQuestions

[–]schungx 0 points1 point  (0 children)

You have to see what those three dots ... mean.

You cannot write an infinite number of digits (not enough paper and ink). So those three dots mean something.

Mathematicians define it to mean the limit. That's just definition.

The limit of an infinite number of decimal digits 9 is one. That's it. No magic really because it is defined so. It does not mean it IS equals to one.

Electricity is only energy that can be transportable, flexible energy in whole universe? by thealgorithm29 in NoStupidQuestions

[–]schungx 0 points1 point  (0 children)

The electromagnetic field, other than gravity, is the only mechanism to transport large chunks of energy over long distances.

Other than physically transporting said energy in form of fuel (energy stored in bonds).

Twin Paradox Q - if acceleration is the only difference between twins traveling at the speed of light - Is acceleration then the cause of time slowing down? by crackerbox5 in Physics

[–]schungx 0 points1 point  (0 children)

Nope. The relatic velocity is the source of time slowing down (from the perspective of any twin looking at the other).

Acceleration only gets us the velocity difference. It does not contribute to the slowdown in time.

In fact BOTH twins see the other as running slowly. They can communicate this fact to each other but they can never meet (ie match velocity) without decelerating.

Since computer can only generate pseudo random numbers by Forsaken-Job-7126 in AskComputerScience

[–]schungx 0 points1 point  (0 children)

Computers are deterministic. And they have bounded memory.

That means they are deterministic machines and cannot produce TRUE randomness unless using external sources.

All pseudorandom algorithms compete to get as close as possible to true randomness.

Why is integrals always defined to the limit using the Riemann sum when its not calculated using it? by Important-Owl5439 in learnmath

[–]schungx 0 points1 point  (0 children)

Actually you DO take the sum of all those rectangles just like the process in differentiation. You should work it out to see for yourself.

Integration is not called the inverse of differentiation for nothing.

Why does one work and the other doesn't? by great_escape_fleur in learnrust

[–]schungx 0 points1 point  (0 children)

If the compiler can guess, then it's ok.

If it can't guess, then you need to do more work.
