@user36790 thanks

@user36790 Never. That's one thing stackoverflow taught me, people rather ask something and look dumb than to just google it

@user36790 I googled "google" and it says page not found :(

amzn.com/0764544209

@BernardMeurer Google is not for "dummies"

@user36790 The only good thing about dummies is they ask questions easy enough for me to answer

@BernardMeurer Are you the "actual" Ninja?

@user36790 I'm aware! I learned C++ with a for dummies book

@user36790 Tsc, that game is too difficult for me

@HariPrasad Yes I am a ninja

@user36790 Zerg Rush ate my search results. WTF?

Or a monkey, it's arguable

@user36790 126 I think

Okay, what the heck is ;/ supposed to convey?

@ACuriousMind A stroke

@ACuriousMind haha same here

You keep using that and I keep parsing it as a sad wink, which doesn't make any sense whatsoever

@ACuriousMind it does.

It's a stroke dude, google "stroke face" it's the same

@user36790 ;)

@BernardMeurer Googling "stroke face" gives me many things, but no emoticons

@ACuriousMind I need a good read, any recommendations?

@ACuriousMind true

@ACuriousMind The face people get when they stroke is ;/

@BernardMeurer Anything by Pratchett

@user36790 Some philosophy or something of the kind, I just finished In Defense of Lost Causes

@user36790 What? He's been dead for about a year now

@user36790

@user36790 Oh please I've read that communist nonsense

@BernardMeurer Oh, you want non-fiction

@ACuriousMind Preferably, never been much for fiction

@BernardMeurer you can read "The jungle book"

@HariPrasad I'm pretty sure that's a movie for children

@BernardMeurer I'm not reading much these days, but I almost exclusively read fantasy and sci-fi, never been much for anything else, so I don't think I can help you

@ACuriousMind Darn it, thanks tho <3

@BernardMeurer you can read "Bansenshukai - A book of Ninja"

@user36790 That looks pretty awesome

I've added on my to-read list; but it's far too big

@user36790 The point is I need something to read between now and august or so :p

@BernardMeurer that might interest you

@HariPrasad Why would that interest me?

@BernardMeurer you are a Ninja

@user36790 Damn, just realized I've never read Tolstoy, good call

Author, book, or both?

@BernardMeurer My favourite: "Moby Dick by Herman Melville"

@user36790 Are yous sure you don't mean The Death of Ivan Ilyich?

@user36790 lol

If by favorite you mean by most impacting "The Horrors and Absurdities of Religion" is by far my favorite

@user36790 Can't find that one then :/

@user36790 //know this? : "The Invisible Man" XD

I've googled it already

@user36790 : are you trying to make fun of me?

:28242524 yes? haha

@user36790 : so what's with the How I am still alive ;/ ?

@user36790 Nope

The E=hf photon is a wave. The particle is a wave. Ditto for the electron.

I understand sarcasm.

@user36790 That I haven't read nor plan to read

@JohnDuffield Are we waves?

@user36790 amzn.com/1560727047

Price's a bit salty

Rs being indian rupee?

@HariPrasad : you are made of molecules. Those molecules are made of atoms. Those atoms are made of electrons, protons, and neutrons. We can diffract electrons, protons, and neutrons, because such particles are waves. That's what the wave nature of matter is all about. So you could reasonably say we are "made of waves". But IMHO it would be going too far to say we are waves.

@user36790 I don't like Gandhi, he nuked my capital in Civilization V a while back. I'm still salty

@JohnDuffield So you mean we may be subjected to diffraction.

@Slereah That asshat

@HariPrasad : no. You can diffract an electron, but you cannot diffract a man.

@JohnDuffield Is that a challenge?

@JohnDuffield really? I don't think so!

kotaku.com/…

@user36790 They are both in the "quantum" sense

@user36790 they are all fields !

@user36790 And maybe "strings"

I think you mean rays of a Hilbert space

@user36790 They are not? The generic electron state (like in an orbital) is pretty delocalized, which justifies calling it "smeared out"

@HariPrasad No, they are not. They may be states generated by a quantum field, but a state is not the field itself.

All electron states are delocalized

@user36790 : electrons are waves. You diffract electrons. In atomic orbitals electrons exist as standing waves. See for example Ehrenberg and Siday's The Refractive Index in Electron Optics and the Principles of Dynamics.

@user36790 It's an electron state. It's as close to something that you might justifiably call "being an electron" as you will come in quantum mechanics.

@JohnDuffield We all love JD

@user36790 star it

@user36790 : the electron is smeared out. It's an extended entity. It isn't some point-particle that has a field. Its field is what it is. Standing wave, standing field.

@JohnDuffield You are really great. Thanks!

Please keep it civil here, everyone is free to talk to other users, or not to talk to them.

Do we need to consider work-energy theorem when considering motion of a block on circular track?

Just my advice

@Slereah Any new songs?

Try that on for size

:28243023 : I'm talking physics, backed by references. And those waves are real waves. Electron diffraction is not some some probability construct:

"This phenomenon is commonly known as wave–particle duality, which states that a particle of matter (in this case the incident electron) can be described as a wave. For this reason, an electron can be regarded as a wave much like sound or water waves. This technique is similar to X-ray and neutron diffraction."

@Slereah It's unkind to say. Note that Stack Exchange's "be nice" policy applies network-wide, including in chat.

people...I just asked a question

dont have fun here

@HariPrasad Darude Sandstorm

@manshu What do you mean "do we need to consider"? What would you want to consider it for?

@manshu Are you from the past?

@ACuriousMind I was having the practice question...in which the block is on the circular track which goes up...

@Slereah Cool stuff

@HariPrasad Yup...In my days time travel was possible

That swedish?

Not a clue

@BernardMeurer Do you have some kind of Swedish fetish? :D

It is, just googled

@ACuriousMind I have a scandinavian fetish

@ACuriousMind just bcz it was a practice question doesn't mean you can't mention the concept behind the question.

Hello!

@manshu Well, but unless you tell us what you want to know about the motion of the block, how are we supposed to tell you if you have to consider the work-energy theorem?

Also, I'm not the best one to talk about the "work-energy theorem" because I still don't see what about it is not just conservation of energy. I've never needed the concept of "work-energy theorem"

Mass of 2m is kept on a smooth circular track of mass m which is kept on a smooth horizontal surace. The circular track is given a horizontal velocity of (2gR)^1/2 towards left. Find the maximum height reached by 2m.

@ACuriousMind this is the question

It's pretty easy comparing to your standards

@user36790 : I'm sorry, but there's crystal-clear unequivocal hard scientific evidence for the wave nature of matter. See for example the Davisson–Germer experiment. Perhaps you should ask a question on the stack exchange about this? Don't forget that the E=hc\λ photon has a wavelength, and we make electrons and positrons out of photons in pair production.

Is necessary free path of atom to calculate cross section of collison?

Good.

@user36790 My name is Albert Einstein and i think light is a particle. :P

happy b'day albert einstein
