What?! Why not?!

user228700

Wow, that's way too...fortunate then, that I got just an adapter.

John Rennie

I was just too late to cancel.

user228700

Oh :-( Thank God I only got the adapter.

John Rennie

When I cancelled the order I got a message saying something like "We will attempt to cancel but the order might have already shipped".

user228700

Ohh :-/

Kenshin

10:01 AM

oh well, it's only money

John Rennie

@Kaumudi.H But seriously, when I said it was what I could earn in one minute that's really true.

Kenshin

@JohnRennie but what about saving for retirement?

John Rennie

(Though only when doing the nuclear power stuff)

user228700

That's...wow.

John Rennie

@Kenshin 259 rupees won't seriously dent my retirement fund :-)

Kenshin

10:02 AM

is that alot @Kaumudi.H?

apparently the big current thing for doing distribution products in QFT these days isn't generalized function but microlocal analysis

user116211

Rs. 250 is the price of Fermi Thermodynamics of Dover.

user228700

Yeah, that's a lot. If u worked there full time, @JohnRennie: U'd be making roughly 14.5 lakh rupees a month. (Yeah, I calculated :-P)

John Rennie

user228700

Exactly x'D

John Rennie

10:05 AM

@Kaumudi.H that would be nice :-) Sadly I only do a few hours per month for them.

Anyway, I'm pleased the laptop is no longer electrocuting you.

user228700

That's still quite a lot :-)

user228700

@JohnRennie Yeah, lol :-P

John Rennie

So basically it's all up and running fine then?

Yep! :-D

Q: Is it possible to cook meat using starlight and multiple magnifying glasses

So you can burn a piece of paper with magnifying glass and sunlight. Light from stars are similar to that emitted by the sun, just much, much weaker. Theoretically, is it possible to cook a thinly sliced piece of meat using powerful magnifying glasses, with gigantic diameter to converge light...

user116211

$\uparrow$ why would one want to cook that hard way?

user228700

@JohnRennie x'D

Kenshin

@Kaumudi.H how many lakh a month is rich there?

@Kenshin The more, the more.

Lunch vs. setting up a hotspot

Kenshin

set up hotspot

user228700

Wokay, but I'm clueless, tired and hungry :-/ I need to set it up so I can use the laptop, @johnr

Kenshin

@JohnRennie do you know hacking?

will you teach me?

John Rennie

10:13 AM

@Kaumudi.H have lunch, chill and we can talk about the hotspot :-)

Kenshin

@JohnRennie is the existence of superhacking a hollywood myth ?

user116211

@Kenshin Yahoo was hacked earlier this Novermber; don't know if that counts.

Kenshin

I dunno depends on how it was hacked and the effort involved

I mean DDOS hacks don't count

and social exploitation doesn't count

(e.g. Phishing for passwords etc.)

user228700

Actually, I was able to do it :-)

Kenshin

you hacked CIA?

how tho

user228700

10:18 AM

x'D Dude, hotspot I meant

Kenshin

oh gud dat's the 1st step

John Rennie

@Kaumudi.H you've set up a hotspot on your phone so the laptop can connect through your phone?

user116211

@JohnRennie, this edit? newtonian-mechanics and energy-conservation aren't required here?

Kenshin

@Kaumudi.H i thought you had internet at home already tho?

user228700

@JohnRennie Yep. We do have wifi but it's incredibly slow and including me, that's three computers using it so yeah.

Kenshin

10:19 AM

3 computers?

John thought your household had 0 computers

user228700

No, my mom and dad, their office computers...I told u guys about it

John Rennie

@Kaumudi.H Cool :-) But bear in mind that the laptop will use a lot of data. It would be worth checking the data allowance on your phone contract to make sure the laptop doesn't gobble it all up.

Kenshin

yeah for sure

what John said

I'm suprised ur phone is better than ur wifi

user228700

@JohnRennie How much data are we talking about? I've got 1 GB per day.

user228700

...at least till March.

Kenshin

10:21 AM

wow tha'ts a lot

user228700

Yeah :-P I study from my phone so I need to watch loads of videos and everything, so yeah...

Kenshin

i think 1 GB per day is probably ok then in my opinion lol

John Rennie

@Kaumudi.H I'm not sure. Assuming your phone uses standard Android you can check the data traffic in the settings.

user228700

@JohnRennie 1 GB ought to be enough, no? (Assuming I don't do much on my phone)

John Rennie

@Kaumudi.H I honestly don't know. Check the traffic in the phone settings. Also note that acting as a hotspot uses a lot of power so I'd leave the phone on a charger while you do it or the battery won't last long.

user228700

10:24 AM

Ohh, okay...

user228700

It's okay tho, I can use my Wifi after 2 in the afternoon...hopefully, the data on my phone lasts till then.

John Rennie

Web sites generally have a mobile and desktop version, and the mobile version is streamlined to use less data. So even just browsing the sites you usually do will use more data.

But how much more data I can't say. You'll need to try it and see.

user228700

Yeah, okay...

user228700

I'll try it for today and see...

user228700

Okay, so that's one thing off my to-do list. Gots to eat lunch before I stop feeling hungry.

John Rennie

10:27 AM

Though having just got the laptop you'll be wanting to play with it all day. Today's usage may not be typical :-)

user228700

@JohnRennie :-P Yes, true.

Kenshin

@Kaumudi.H what background are you going to choose, light grey?

user228700

Okay, I'm gonna leave it to transfer all my files while I go have lunch. Phew, all I've had in 8 hours is a very small glass of chocolate milkshake

user228700

@Kenshin I was thinking this:

user116211

11:38 AM

@JohnRennie, Did you listen to the Deck the Halls? It sounds nice.

user116211

Deck the Halls

"Deck the Halls" or "Deck the Hall" (which is the original version of the lyrics) is a traditional Christmas, yuletide, and New Years' carol. The melody is Welsh dating back to the sixteenth century, and belongs to a winter carol, "Nos Galan", while the English lyrics date to 1862. == Lyrics == The English lyrics were written by the Scottish musician Thomas Oliphant. They first appeared in 1862, in volume 2 of Welsh Melodies, a set of four volumes authored by John Thomas, including Welsh words by John Jones (Talhaiarn) and English words by Oliphant. The repeated "fa la la" goes back to the earlier...

John Rennie

The trouble with Christmas carols is that we get bombarded with them as children and we quickly get sick of them and go and listen to grunge or death metal instead :-)

2

user116211

Ahh! got it ;P

John Rennie

Christmas carols are good fun to sing in four part harmony. I've been in various choirs singing carols and enjoyed it. But they're only good fun to sing. I wouldn't sit and listen to them!

@JohnRennie: I swear, I'll stop updating you every now and then after today, but something disastrous just happened. I deleted the "Desktop" folder in the Admin folder and lost the desktop :-P

user228700

I restored it from the recycle bin of course. I told u I suck :-P

John Rennie

@Kaumudi.H Admin folder?

user228700

@JohnRennie The "Kaumudi H" folder...

John Rennie

user228700

@Kenshin :-) Won't.

John Rennie

11:51 AM

Like so?

user228700

Yep.

user228700

Didn't know that I wasn't supposed to just delete that. It seemed useless so... :-P

Kenshin

@Kaumudi.H why would you delete the desktop folderfor?

John Rennie

It wouldn't have done any serious harm. The Desktop contains the icons and stuff that appear on the desktop, but you can recreate them.

user228700

@Kenshin Dude, I didn't know that I wasn't s'posed to!

Kenshin

11:53 AM

lol k

i'm sure u probably don't need to delete anything that was on it when u go tit

user228700

@JohnRennie I refreshed the desktop and it kept telling me something along the lines of "The desktop doesn't exist" :-P

Kenshin

lol

I think u need a new laptop

user228700

x'D I restored it from the recycle bin, dude.

Kenshin

jks

John Rennie

I suspect that if you rebooted it would recreate the desktop. If not you easily recreate it yourself.

Kenshin

11:54 AM

I hope

user228700

@JohnRennie Ah, I see.

Kenshin

ah so it's all working

user228700

Of course it's working!

I can't believe this is like... mine :-o

John Rennie

@Kaumudi.H I have got a backup of the laptop if anything disastrous happens to it, though obviously it would be a few days if I had to post it to you.

Kenshin

11:57 AM

@Kaumudi.H just be careful what you look up though, as @JohnRennie has installed a keylogger on it, and tracks everything u do

user228700

@JohnRennie Now that you know exactly how much I suck, I request you to please please hold on to it.

user228700

@Kenshin No, he wouldn't. I mean, it's useless, rigging this laptop-I don't do anything fancy. Doing that to the laptop of someone rich and famous. Now that would probably be fun :-P

John Rennie

I generally keep backups of any laptops I set up for people as they have a habit of breaking them and needing to be restored :-)

user228700

@JohnRennie U see, not everybody is as awesome as you :-)

user228700

This keyboard is a whole lot smaller than the one I'm used to and some of the keys are in weird places... I'm getting used to it :-)

Kenshin

12:00 PM

@JohnRennie

is enthalpy of vaporisation always greater than enthalpy of fusion?

or are there some exceptions?

user116211

@Kaumudi.H You'd get acclimatised with it; initially I had problems too; but now I can even type blind-folded.

Kenshin

@Kaumudi.H the keyboard is smaller than an iphone?

John Rennie

@Kenshin generally yes, which makes sense because you separate the atoms/molecules much farther in vapouristaion than in melting.

user228700

Awesome, I've transferred all my files...and that's about it. I only have to download VLC media player and I'm done "playing" with it.

user228700

@Kenshin x'D No. My mom's dying computer.

user228700

12:02 PM

@MAFIA36790 Yeah :-)

John Rennie

@Kaumudi.H do you use Google Drive for backing up your files?

user228700

@JohnRennie Yep. For the most part...

Kenshin

@Kaumudi.H perhaps you can send your mum's dying computer to @JohnRennie who can fix it

user228700

But I have way too many files to transfer them all to Google Drive.

user228700

@Kenshin Honestly, our experience with TNT has left me a bit scarred to try anything else anytime soon :-P

user228700

12:05 PM

Oh, yeah, @Johnr last question...I hope.

John Rennie

@Kaumudi.H Yes?

user228700

What's the buttony thing (oh, isn't my vocabulary just out of this world? :-P) below the volume toggle buttons on the keyboard?

user228700

Actually, there are loads of holes...and I dunno what they do, except for the USB port and...wait, is that an HDMI port or whatever?

John Rennie

There are three buttons on the right hand side, vol up, vol down and mute. Is that what you mean?

user228700

No, below that.

John Rennie

12:10 PM

Ah, the horizontal bar?

user228700

Yeah, that.

John Rennie

That's a fingerprint scanner. However it doesn't really work so no-one ever uses it.

user228700

@JohnRennie :-P Good to know.

John Rennie

It won't do anything useful, or indeed anything at all. I don't think I enabled it.

user228700

12:11 PM

What is it with this weird joystick mouse? It's almost completely useless.

John Rennie

The joystick mouse is missing the rubber button that normally goes on it.

user228700

Yeah, but it still works and seriously, who uses this?

John Rennie

So it won't work as well as it should. But anyway no-one ever uses the joystick mouse as it's pretty rubbish.

user228700

Agreed. Idc, I'm not using it anyway :-)

John Rennie

Some people really don't like touchpads, and for them I guess the joystick mouse is the best option. I doubt many people use it though.

user228700

12:12 PM

Oh, wow! There's a mobile version even for the laptop!

John Rennie

Mobile version of the PSE site?

user228700

Yep! The chatrooms in particular.

John Rennie

Yes, you just use a different URL. But I find the full version is a lot nicer to use. I guess the mobile version will be better if you find you're running up against the data limit.

user228700

Yeah, the full version is definitely a lot easier on the eyes.

user228700

Wow, I am so glad to be typing this fast again :-D

John Rennie

12:15 PM

The small keyboard does take a bit of getting used to, but it is a very nice keyboard on the Dells.

user228700

It looks beautiful, the whole thing :-)

John Rennie

The later Dells switched to a chiclet keyboard and I don't like the feel of those keyboards as much as the older keyboards.

user228700

Oh, I see...

John Rennie

@Kaumudi.H The Latitude E6x30 range were released about four years ago, but i think they represent something of a high spot in Dell's business laptops.

The more recent laptops are lighter but I don't think they look and feel as good.

user228700

Ah, I see. I don't mind that this is heavy. I kinda like that it is, for some reason :-P

John Rennie

12:18 PM

I have several of these Dell laptops for my own use and it will be a sad day when they eventually die of old age.

user228700

@JohnRennie Why dyou need multiple laptops?

user116211

@JohnRennie You should put them in eBay auction.

user228700

@JohnRennie Wow, I see.

John Rennie

Laptops are cheap these days. For example look at this one.

@JohnRennie: When you're done using 'em, dyou shut them down or dyou put them on hibernate?

Kenshin

@JohnRennie, Have you used Laptops other than of Dell like HP?

John Rennie

That's a really awesome laptop, and for £199! I'm seriously, seriously tempted. But ... well .. I really don't need any more laptops :-)

user228700

Since I suck so much, I googled all this and found that for an SSD, the hibernate mode will work a lot better than shutting it down completely...what does the Guru recommend?

Q: Why north-south pole are very cold?

I know in this regions sunlight barely fall & sometimes wont fall at all. If sunlight doesn't fall very long time it doesn't mean that whole region should become very cold. for suppose: if i leave a hot cup after some time it becomes cold because of heat exchange with surroundings. Earth havin...

John Rennie

Or this one. Not quite as powerful but even cheaper.

@MAFIA36790 that has to be a duplicate, surely?

@Kaumudi.H I always shut down my laptops when I'm finished for the day. It I've only stopped for lunch I'd probably just hibernate them.

Ah, okay, thanks! :-) I'll leave you alone now.

user228700

Ooh, btw, that case is so good! Thanks for just "throwing it in"! :-D

John Rennie

Actually I think I bookmarked that page. Look in the bookmarks on Chrome and/or Internet explorer and see if that page is there.

The case doesn't quite fit as it's intended for a slightly smaller laptop. It's a bit of a stretch getting the laptop into it.

user228700

@JohnRennie Oh, I haven't tried yet :-P

John Rennie

But if you need to carry the laptop to college in a backpack the case will do a good job of stopping it from being scratched.

no chrome is the best

Kyle Kanos

@Kenshin If you're okay with internally-built spyware, sure.

John Rennie

@Kaumudi.H Yes, though I don't add permanent bookmarks much.

Don't you guys know about Opera? Huh?

John Rennie

12:44 PM

@Kaumudi.H When I want a temporary bookmark I just drag the URL to the desktop, then delete the icon a few days later or when I no longer need it.

@MAFIA36790 Sadly, Opera is just loaded with bloated code which make it a huge waste of space

user228700

@KyleKanos Wow, that sucks. His/Her answers were pretty great.

John Rennie

12:46 PM

Kenshin

@KyleKanos Ah, that explains why Doeromon's gone as well.

hi @Kaumudi.H

Ramanujan

@Kenshin lol

user116211

@KyleKanos, there is spoiler-free review in Movies&TV coming; if you want.

Kyle Kanos

@MAFIA36790 Negative. I want no reviews. I've watched only the first of the trailers and nothing since

Kenshin

what movie?

Kyle Kanos

@Kenshin There are other movies worth ignoring the world over than Star Wars?

Kenshin

12:58 PM

oh yeah rogue one is pretty gud

user116211

@KyleKanos okayish.

Ramanujan

This is not movies chat room : go here chat.stackexchange.com/rooms/1888/the-screening-room

ACuriousMind

If you find yourself deleting every message you write, maybe think a bit more before writing :P

@Kenshin "competing"? Chat is not a competition.

user116211

One can discuss anything here (exc. politics).

Kyle Kanos

There's like 1000 chat rooms out there

Ramanujan

1:02 PM

@ACuriousMind so we can discuss anything here?

Kenshin

@Ramanujan excluding politics

and excluding gender differences

Kyle Kanos

We can talk about how GR is wrong and we need to re-think SR too

ACuriousMind

@Ramanujan Sure, as long as you stay within the Be Nice policy. This room has never had a topic restriction, although you might be asked to take unrelated discussion elsewhere if you're interrupting a physics conversation

Ramanujan

Any one play 8 ball pool here? :p

Kenshin

no

I prefer studying the law of reflection theoretically

Kyle Kanos

1:04 PM

I have in the past, but not regularly ever

ACuriousMind

@KyleKanos Pretty accurate, I see 54 pages with 20 rooms each.

Ramanujan

Someone here to challenge me now in 8 ball pool game?

Kyle Kanos

No

That would require me leaving my wife & kids

Ramanujan

@KyleKanos why so?

Kyle Kanos

Well, leaving them for the day at least

Ramanujan

1:08 PM

@KyleKanos I mean this game play.google.com/store/apps/…

Kyle Kanos

Oh.

Ramanujan

Any body?

Kyle Kanos

I'm gonna pass. My wife thinks I spend enough time playing my two brothers in chess on the phones (we really make a move or two each per day). I imagine this would driver her over the edge

Ramanujan

@KyleKanos lol,really one move per day?

Kyle Kanos

Well, on days off we can squeeze in more. But yes, I try to do work at work

And I work 12-ish hours per day, Mon $\to$ Fri

ACuriousMind

1:13 PM

@Ramanujan You realize that "8 ball pool" has been an actual game played by actual people at actual tables for much longer than those computer games have existed, right?

I.e. when you ask someone if they "play 8 pool ball", most will take that to mean that you asked them whether they play the physical game regularly.

Kyle Kanos

@ACuriousMind All I can think of now is the line We have a pool!? from Wall-E

Ramanujan

Try playing rapid chess

@ACuriousMind I don't even know how to play physical game,but I enjoy playing it virtually and it's easy

Kenshin

@ACuriousMind I think this would depend on culture and country

I connect in my home (220V) in series circuit two lightbulbs. The first lightbulb is 15W and the second is of 150W. I calculated that the electric current through the 15W lightbulb is much more lower than the one in 150W. Why would the first lightbulb illuminate almost it's normal light, and the 150W would illuminate almost anything?

Kenshin

2:08 PM

@PichiWuana if they are in series, the current should be the same

DHMO

In the [photoelectric effect](https://en.wikipedia.org/wiki/Photoelectric_effect), when we fix the intensity and the frequency of the light, and only vary the potential difference between the metal plate and the collector, we can observe the effect of saturation current.

My textbook claims that it is because at the saturated current, all photoelectrons can reach the collector.

However, I am confused, as the p.d. is positive, which should promote every electron to the collector. Then, how could some electrons fail to reach the collector?

ACuriousMind

@DHMO not all electrons are emitted in the direction of your detector/the electric field, i.e. they might have velocity components pointing away from it. For them to hit the detector, the electric field must be sufficiently strong in the direction of the detector, not merely pointing towards it.

DHMO

@ACuriousMind the voltage that corresponds to saturation, is it exactly the opposite of the stopping potential?

ACuriousMind

@DHMO It should roughly be, yes. But we can't determine saturation as well as "no current", so we prefer to use the stopping potential.

DHMO

@ACuriousMind I don't understand the middle sentence

the "as well as no current" part

ACuriousMind

2:16 PM

It's easier to determine when the current is zero than it is to determine when it is saturated

So we usually use the "stopping potential" and not the "saturation potential" as the quantity we measure for the photoelectric effect.

DHMO

oh, the "as well as" was not idiomatic

ACuriousMind

Yeah, I see how that was confusing wording, sorry about that

DHMO

I think this contradicts with the hypothesis

ACuriousMind

It does; if that picture is right my idea of what the saturation current is is wrong.

DHMO

but I don't think your idea is wrong

and I urge you not to trust the graphs on the internet

because I've seen more ridiculous graphs
