How did you know? Yes, I am 27 lol

@PeterCordes I accepted that answer becose it looked best to me, I dont understand anything so its not surprising that more knowledgeable people like you disagree with my choice. If I knew your opinion sooner I would pick probably something else so other people who will read this in future will read the best answer, I just didnt knew what a good answer was supposed to look like since I am total noob and have no knowledge about this topic.

Is it that instruction set what limits how much stuff can one core do at same time?

Make the 1 core have more transistors so it can do more stuff per clock.

Amybody knows if piezo materials change just shape or do they also change volume/density? I want a piezo material that expands in one direction but doesnt get thinner in any other direction.

Thank you Blue

I just have one question,what should I do if I used to login with facebook but will delete facebook today? How will I keep the ability to login in future after my facebook account no longer exist?

Anybody "home"?

Hello

Does anybody know Italian language?

Poise law anybody?

When that Poiseuille law calculator says flow is 1 m/s and pipe cross section is 10 cm2,is that liter per second or is that flow velocity only inside center of pipe where the flow is fastest....

Becose flow velocity is not uniform inside pipe due to viscosity/skin drag/boundary layer

endmemo.com/physics/poiseuille.php

I am using this Poise law calculator and it gives result for mass flow rate in velocity number,like meters per second.My question is,if the pipe have 10 cm2 cross section,and it say s volumetric flow rate is 1 m/s,does that ,mean that 1 liter per second flows through?

Hello everybody!

I believe you... I have only experience with DSP so thats where I know that word from.I dont have any idea where else.and how much is it used

Thank you Senpai Rennie <3

Oh yes!

For example if you have sinewave fuction,and you end it abruptly,so called that word,its not decimation,its that other word

Its word that is used extremly often in DSP,and I thinj in mathematics too.... for example if you have some "spiky" geometric object,like dodecahedron,and you "crop" the protruding spikes,they dont call that cutting or cropping,they have specific word for that

Yes

Do you know that word that DSP and mathematician guys use to describe cutting some fuction or geometric shape?

.Do you know any picture with realistic redshifted hydrogen?

I want to ask,where can I see how does redshifted hydrogen glow looks like? I saw hydrogen glow in glow discharge plasma tube,it had beautiful color.I did small search on internet and it seems that when looking at hydrogen glow from other galaxy,the 4 visible hydrogen wavelenghts get shifted by about 5%... I found graph that shows how the individual lines get shifted,but I didnt found anywhere how it looks to human eye where all these wavelenghts are combined.

Hello everybody!

lol ok well anyway,thanks for helping me,and others for free,thats rare activity in this world,live long and prosper

I was thinking you are young becose you look young in your avatar photo.... I guess its old one.

Retired? How old are you?

What are you doing in real life John Rennie? Are you teacher or student or scientist? I always wonder why would someone spend significant amounts of time in Stack exchange helping random people on internet for free

Thanks for explanation John Rennie

It looks to me like superposition of longitudinal and shear waves that travel at same speed in same direction

shesr = shear

When longitudinal and shesr waves meet,does it create Rayleigh wave where they coexist?

Thank you John Rennie.... when you say Rayleigh wave depends on shear modulus,do you claim that Rayleigh wave is not combination of longitudinal and shear wave?

The Rayleight and Love waves arent pure shear waves

You was describing shear wave now right? Anyway,I just found website that says Ryleight aka Surfacs waves are indeed superposition of longitudinal and shear wave

Hi John Rennie... do you know the Rayleigh wave? Isnt it just combination of longitudinal and shear aka transversal waves?

Hello,anybody home?

Well,bon apetit bro,thanks for explanation,I hope that I understood it correctly

You repeat and repeat that you said what it means, I just wanted single confirmation that I understood you correctly,when every time i i ask if thats right,you write that you already explained it,then I dont know if I am wrong or right

It says how many molecules of ozone we need to absorb 100% of incoming light if we spread all these molecules evenly in 1 cm2 area

Thats true,but I belive that graph is not about specific absorbtion in certain place on earth with certain effective thickness of ozone per certain surface area,its intrinsic absorbtivity of ozone

Why should they? By your explanation,no thickness information is needed

So if it says on absorbtion vs wavelenght graph that at 255 nm its 10-17 per cm2.... that means each molecule will act as black hole where one side have surface area of 1000 square picometer

I am confused,if I understand your explanation correctly,that is each molecule will absorb all incoming light in surface area of certain size,then I dont need any information about thickness to make usr of that graph

That graph is supposed to show intrinsic absorbtion characteristic of ozone as substance,there is no mention of thickness anywhere

I found no mention of thickness,I just found that graph in google images... do I need to have knowledge of thickness of the ozone to make use of that graph? I was thinking that graph can be used alone,without any aditional information concerning thickness

You mean that graph? I dont know,I just randomly found it in google images

If only 100 000 000 000 000 then 0.1% gets absorbed
