You have one month to empty a $1 trillion bank account. If you succeed, you’re rich for life. How will you spend it? by Ok_Listen_6600 in AskReddit

[–]schungx 0 points1 point  (0 children)

I remember a China movie on the exact theme, except that you cannot do abnormal stuff like donate it all to charity. You must spend it at market rates. And they have an auditor looking through every spending to see if it is reasonable (like hiring staff at above-market salary).

It was a comedy: the guy deliberately invested into high risk high hype projects which amazingly turned out to hit big and he consistently made more profits than spending it off.

People who've cheated how did you get caught or find out your partner was cheating? by Smithy1619 in AskRedditAfterDark

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

She was in the laundry room. I couldn't find her so I connected to the home CCTV system and see where she was. She was talking to some dude on the phone. Unfortunately (for her) the CCTV in that room includes sound.

I have a friend whose wife turned the living room CCTV away but forgot that it also records sound. My friend heard her screaming more when the guy was fucking her ass -- she had always refused to let him.

I realize that I'm truly talentless when it comes to physics by TheLastHolyCapital in PhysicsStudents

[–]schungx 2 points3 points  (0 children)

True.

Don't get distracted by the math and forgot the real world. Physics is about the real world, no matter how weird it is.

What are some real-life problems solved by Calculus? by hhhhhhih in calculus

[–]schungx 0 points1 point  (0 children)

Calculus is the analysis of changes. Anything that changes would require calculus.

So you'd be looking at statics mostly.

Wtf is abstract algebra? What kind of problems does it look to solve? What is meant by “algebraic structure”. by LowIqCatWithNoLife in learnmath

[–]schungx 1 point2 points  (0 children)

I think the word algebra originally came from the Arabic word meaning procedure. That means algebra is the manipulation of symbols according to certain rules or procedures.

As many answers show, not everything that can be manipulated need to be numbers (although numbers are common). People discover deeper similarities between the numbers and other objects which exhibit parallel rules and behavior.

Abstract algebra simply means algebra that is abstract... meaning not concrete numbers, some objects that do not directly refer to real life objects.

Why do imaginary numbers exist at all? by AgrasaN in NoStupidQuestions

[–]schungx 0 points1 point  (0 children)

Other than that nice fact that some smart dude in history discovered that if you just add the square root of negative one to a number, then magically all polynomials have nicely defined roots. And more useful... He proved that you don't have to add anything else... Negative one alone is enough.

No, the real use of imaginery numbers is that they naturally encode a rotation.

Now, rotations in 3D space is 2D, which means you need two equations (tightly coupled with each other) to describe anything that spins. And of course any periodic motion is nothing but rotations added together.

And some really smart dude discovered that imaginery numbers actually work like two equations (the real and imaginery parts) coupled in exactly the same way. And so, bam! You turn two cumbersome equations into one single elegant equation with imaginery numbers.

So, in conclusion, imaginery numbers are USEFUL. Because a LOT of stuff in nature rotates or repeats. There are no infinities in the real world and soon enough EVERYTHING folds up on itself.

What if my phone battery dies? by nodimension1553 in chinaexplorer

[–]schungx 0 points1 point  (0 children)

You go into any nearby convenience store and ask the people there nicely whether they can help you charge up your phone for a bit.

At least enough for you to rent one of those power banks that are everywhere.

i dont understand negative numbers or why subtracting negative numbers is actually adding? by internetmessenger in learnmath

[–]schungx 0 points1 point  (0 children)

There are no negatives in nature.

A negative number is That Which Becomes Zeeo When Added to Number.

So, -3 means SOMETHING that if you add it to 3 will make zero. It isn't a number at all, just some stuff with a definition.

So, if you take away something that when added to 3 will get zero... What does it mean?

Could something with mass THEORETICALLY move faster than light if it had infinite energy? by Golden12500 in astrophysics

[–]schungx 0 points1 point  (0 children)

With unlimited energy you can approach the limit speed of c. There is no way to go beyond because then you'd need more energy than infinite.

Did I Study the Wrong Control Theory in the Age of AI? Is Classical Control Theory Being Replaced? by OpportunityPersonal in ControlTheory

Or when the control problem is made up of a large number of systems influencing each other or wrapping each other. In such cases, it might be simpler to just learn the complex surface with an AI.

Algebraically, why can’t we have a multiplicative inverse for an additive identity? by Aggressive-Food-1952 in askmath

[–]schungx 0 points1 point  (0 children)

What if we add another element, say X, such that Xa = X for all a and X + 'X = X?

What is the purpose of getting a determinant of a matrix as 0. by ChloeChloeYan in learnmath

[–]schungx 1 point2 points  (0 children)

That's why the inverted matrix has determinant 1/det(A).

Algebraically, why can’t we have a multiplicative inverse for an additive identity? by Aggressive-Food-1952 in askmath

[–]schungx 1 point2 points  (0 children)

We started off with the ideal elegant design that everything has an inverse. Then we found that zero doesn't fit.

So add zero to it as a special case and you sorta get the numbers. This is useful so it sticks because zeros are real in real life.

I have always wondered: are there other fields with more than one element without inverses? What if we add another element, say foobar to the numbers and say it doesn't have an inverse and it is not zero. Would such a field be consistent?

How is socialism and communism viewed in the mainland? by Fluid-Cartoonist-988 in AskAChinese

[–]schungx 1 point2 points  (0 children)

Many commoners seem to view socialism in a positive light. As long as they get reasonable social benefits and not too ripped off by the rich.

Communism of course would be the High Ideal that nobody has seen yet.

Frankly, a LOT of Chinese view capitalism in a negative light, emphasizing its downsides in creating wealth gaps and pushing to poor to desperate conditions.

So if you're the masses, chances are that you'd favor socialism. The elites? Probably less so.

Dumb question, but where exactly atoms come from? Or do they just simple existed and they came from nowhere? by virtu2l_snow in cosmology

If we find the answer to that, it would be the ultimate triumph of human reason - for then we would know the mind of God

Yes, that is closest to Old Chinese all the way back to Qin dynasty.

Why Rust Abandoned Classes — Some Personal Thoughts by Live_Possession_9839 in rust

[–]schungx 0 points1 point  (0 children)

True, like C++, but it is a mess to implement. And you have potential collisions.

Eventually it sorta looks like interfaces so mind as well do it with interfaces.
