https://youtu.be/s86-Z-CbaHA The Banach–Tarski Paradox: According to it mathematically it is possible to split a real physical object into multiple parts.. and combine them to obtain 2 copies of the original object!! No loss of mass, no loss of matter! simply speaking 1 + 1 = 1 This is not possible in our world though coz maybe we lack the technology to do it? dont know.. But theoretically it SHOULD BE POSSIBLE! Such interesting things can only happen in maths >.>

Lishifu @hakutaku Math: the world of logic and rationality :D.

. @vezax but the world doesn't just run on pure logic and rationality that humans know (proven by quantum mechanics and relativity) #ENTP lol

Lishifu @hakutaku Our parents also tend to force kids to go to a cramming school to learn Mathematical Olympiad...I found their solutions to a problem is way too complicated..There are easier, quicker ways to work out the right answer..

. @vezax Yes here also everyone are forced to join cramming schools for olympiad and entrance. .. Totally agreed, there are easier and quicker ways to solve them, infact there are more than one to solve maths always! Some times when there are really good teachers in the cram schools they teach short tricks XD most of the times u have to figure it out urself :p

http://a.nime.me/0116/3369/img_6577.png ^this question was really difficult ^^ Finding the upper limit was very easy, where i got stuck was finding the lower limit.. and its no wonder i got stuck there as i needed a derivative identity this time which i didnt know and had to work that out from scratch -_- it was still fun XD the answer is all numbers from range of e to 7.. (e being the lower limit and 7 the upper limit)

. @vezax range (e,7)

. @vezax i took around 15 mins solving that, coz i had to work out the derivative from scratch >.>

Lishifu @hakutaku ! Right answer! Sugoi!

. @vezax thankyou :3 SUGOOOOOIIII

Lishifu @hakutaku I will make a post about our conversation about math on my Chinese social media （＾＿－）...Later....

. @vezax lol i will become famous in china XD waitt.. chinese have a seperate social media?

. @vezax is it restricted for non-chinese to use?? or is it some facebook group?

Lishifu @hakutaku only my schoolmates heh....Only Chinese...I think most will be indifferent....

. @vezax i see...

Lishifu @hakutaku I simply know one math personwho is doing his master degree in the university of Tokyo in person...Other acquaintances dislike math ..

. @vezax u also dislike maths i presume? >.> maths is amazing when u get to know all the possible physical applications it can make! moreover its a giant puzzle :3

. @vezax And there is soo much imagination possible in maths which cannot be applied in real world! So that makes it like a fantasy too... eg. The Banach–Tarski Paradox! i will say about it later :3

Lishifu @hakutaku （＾＿－）I disliked math because of many factors...Perhaps I hated being ridiculed by a math teacher in front of 50 students and this case led me to be bullied when I was in middle school...I failed to do well in math since then...

Lishifu @hakutaku Math is also a universal language hah

. @vezax yes maths is a universal language, all biological and human functions also follow maths.. I am sorry to hear that :/ But u raised from there and won over ur obstacles, So that makes u amazing :P maths teachers are the worst.. tbh

. @vezax i mean not all the math teachers, the ones i met in my 11-12th.. they have too much pride and ridicule students who don't get the answers.. i never liked that.

http://a.nime.me/0116/2967/img_6573.png ^Just saw your translation few mins back XD it was a cool question, but next time give the necessary trignometric identities and the sine/cosin laws along with it :V i didnt have practice so took a time finding these identities and laws necessary for it :P THE MINIMUM VALUE OF CosC is (√6/4)-(1/2√2)

. @vezax can also be written as ( √6-√2)/4

Lishifu @hakutaku ・㉨・Amazing! How much time did it take you to work out the answer?

Lishifu @hakutaku Do you want more?

. @vezax few mins, not sure... within 5 mins for sure XD actually if i remove the time taken to find the identities then 2 minutes :P

. @vezax i would'nt mind more.. its a good excercise XD

. @vezax just dont put the time limit.. it puts psychological pressure on me haha

Lishifu @hakutaku Sugoi!

. @vezax SUGGGOOOOOII

Our bread is not that hard I promise ^^. Maybe the swedes just need to make better knives you know. And have the correct attitude to cut it.

I will say "Who are you? " I used to come across estranged relatives who said that as well. https://wx1.sinaimg.cn/mw690/87d788b2gy1fsbsxygp97j20kr0req5g.jpg
