@Bohemianrelativist Ah. It's a personal pet peeve of mine when people say "do <something>, everything will be fine". They never understand that things don't just work like that, and especially sleeping can help some things like a headache but not months to years of feelings of isolation. That just doesn't make sense.

Yeah, I wouldn't expect him to necessarily be able to help you. But if he can't then like you said, why bother asking if it'll just make them feel worse? Anyway, that's too bad. It's good that some in-person classes are coming back though - sucks that you don't get to enjoy it much but hopefully it is a good sign and a step in the right direction.

@Bohemianrelativist Haha, no. I just came up with that because I was interested in particle physics. Never knew much about it though, and I'm in school for CS right now anyway and don't plan on going into physics. It's just a username, not much else to it :P

hyper, codegolf.stackexchange.com/questions/237983/… is a question after my own heart although i would love to see more answers in languages that didn't natively support matrix operations.

i mention this only because it popped up on a list of recommended posts, and you're a code golfer.

otherwise it's like, matlab, 5 bytes, IsThisABasis( ), but cool. hope to see x86 assembly.

amwhy, where are we on "WHOOSHED"? is it a word?

"Whoosh!" is the name of an album. If we turn a noun into a verb, we can make it past tense. I am whooshed, I have whooshed, I was whooshed, I have been whooshed.

The question is whether we accept turning nouns into verbs.

Verbing is a time-honored way of etymologically converting nouns into new words, as old as Shakespeare.

Others consider it a crime against the language.

i'm seeing uses of it from at least the 19th century. i think we're safe.

i don't know how people sorted this out before google. now you can just run a few searches and see if you're in good company.

why is it considered a crime? @Mast

some people just feel it's crude.

i used 'determinant' as a verb the other day in the math chat. i probably wouldn't do that while teaching, it might confuse people, and a big part of learning math is getting the new words straight in one's head. but among chatters with enough knowledge, why not?

I still don't get it

dictionaries usually list a word as noun first, then a verb (depending on common usage)

Is that^ crude

no, it's specifically the process of using a noun directly as a verb that some consider crude

using the example leslie gave, "determinant" is a noun but if one were to say "determinant the matrix" it would be reasonable to assume they used it as a verb to mean "to take the determinant of"

yes, context is king

the "king" is not crude :-)

i do like how english makes it so easy

saves time in talking about determinants, too, especially matrix minors. i think that's where it came up

that thing you determinanted to compute the minor

if you want a challenge, try explaining what contrast means without using the word comparison

i prefer as few challenges in life as possible

Grace me no grace, nor uncle me no uncle.

Richard II

i've never seen richard ii

that's something of a shakespearean 'deep cut'

The problem reduces down to the impossibly of explaining what "unlike" means without using the word "like"

i'll quiz my daughter on this tomorrow and see if she can do it

she's at an age where she makes all kinds of connections that we don't think to make when we're older

great, ill look forward to the results :-)

please ping me!

she has different hand signs for the number three and what she calls "lowercase three"

will do, if she says anything interesting. :)

I would guess lower case three is 2.999...

lowercase three is your middle, ring, and pinkie finger

three is either index/middle/ring or thumb/index/middle

coolio

she's very insistent about this, and it has persisted for weeks

i'd love to know how the mind works at that age

i'd gone over 40 years without thinking about lowercase three

the pinkie is the lowering idea 💡

try it with her toes

Index, middle and ring is Roman three AFAIK.

...and, as we all know, they never had a zero

0️⃣

they never thought about variables because X was always ten :D

I'm not sure whether that joke is great, awful or both.

@hyper-neutrino because of that issue, I cannot continue here.

@hyper-neutrino I think he is just lazy to think about the solution - solving human affair can be as complicated as solving a math or scientific question in that it requires profound strategies - so he said that.

@Bohemianrelativist Very well, then. I wish you well. Good bye.

@hyper-neutrino Determinant the Matrix is a lazy replacement for "Find the determinant of the matrix." I sure wouldn't want "set the elements a, b, c, d" in elementary set theory!

Especially on an international site, where proof is often used to mean "prove"!

Sorry I'm late to the party!!

@amWhy I have to look for other position.

but the hostel is so bad for studying and looking for research positions.

so you can see how important that issue is.

@Mast Indeed. Counting: one is forefinger alone, two is forefinger and middle finger, three is forefinger, middle finger and ring finger, four are the four fingers minus the thumb. Five is all five "digits" from one hand. But I do not no if this is the case in sign-language!

We don't name our toes that way, big toe, perhaps, or pinky toe. Why is the thumb, called thumb, and not "big finger"?

Y'all are still wondering who let the dogs out?

@quid depends, u got the ans?

@Arjun you look suspicious.

If not I'll blame the room owner.

:-)

@quid did it look like that?

i am maybe

Yes.

i've been trying to print a few papers for hours now

paper mismatch-__-

i am using the same paper as always

@Arjun Manually select the printer paper/drawer in the printer.

It's not actually looking at your paper, it's seeing a difference between the papersize selected in the printjob and the drawer selected.

@Mast i actually did that too

something's broken ig

maybe it's a new innovation in printer technology. we've seen the ones where they won't print black and white if one of the color cartridges is empty. maybe this one won't print in one size unless loaded with paper of all sizes.

or perhaps it's offering aesthetic advice and thinks you are using the wrong size of paper for your paper.

i have another printer somewhere, gonna look for it tomorrow

it's cool that you still have a printer. the last time i needed one i had to go to a shop. it was cheap, but inconvenient.

I got transferred to another office location last year. When I print something in office, sometimes old printer gets selected and the printouts come out in old office, which is about 10 km from the new office.

hahaha

printer is so important for doing scientific research. I have had the problem of eyestrain due to reading on monitor from time to time.

i have access to one at my office, but i'm almost never there because it's still closed for the pandemic. and it is a 30 minute drive away. there is a print shop about 5 minutes from here. the inconvenience keeps me from printing out 'non-essential' things :)

Did I miss The @quid ?

@amWhy did you? :-)

@quid Hello!

Hello

WHO SCOOPED THE CAT'S LITTERBOX?

Now we have an A and an I!

i did. oh wait, you mean letters.

I have been deprived of my office, so have no access to a printer now. They cheated me a person would soon arrive to occupy that office and hurried to take the key to that office from me. But yesterday I found that office has no new occupier and it's just my name was removed from the office tag.

Hello!

@soupless Hi there!

Is it okay to ask questions about math here?

soupless, I think that’s okay because we are regulars here. amWhy said so once. :)

Oh, okay. I will keep this in mind.

I just want to confirm since I didn't even think about it in the first place. If the terminal side of an angle is the x-axis, it's said to be in its standard position. What if the terminal side is not the x-axis, is there a name for it?

hi

I have a basic doubt

if anyone could help

hlo????????

@SamyakMarathe You may continue :)

x/x is discontinuous at 0 right?

this idea always confuse me, because LHL=RHL, although it is undefined at 0

under the usual conventions of function algebra, x/x is not the same thing as the constant function 1, and is indeed discontinuous at 0 by virtue of failing to be defined there.

the math.se chatroom could use these questions, instead of endless repetition of a question that has been there for almost 12 hours now :D

I think that Pakistan math student only wants to have trivial conversation with me.

When I last time showed my anger to him by saying if you cannot help with this, then what else can you help? Linear algebra? He said:“dear, I don't have time now. I have a lot of work to do. I used to have have more time.better to watch YouTube to learn linear algebra."

Then l said:"I really don't need to study pure linear algebra, but I just want to ask some questions l see in Wikipedia when I study tensor network." Then he did not reply me.

Then I put my WhatsApp demonstrated message as "l only want meaningful conversations."

Then after a period, he asked me my things again.

I didn't reply. Then after a period, he asked something like how are you again.

Obviously he just wants trivial brainless conversations.

Yesterday I messaged him:"don't call me back if you don't have time for me."

He seems not understand me as he said: is this what the landlord replied you?

I said:"I will see who's really sincere."

Then he doesn't reply.

I hope he won't ask how is everything some time later, like he does not know l have been angry at him.

I used to think math students should be serious people, but he destroys my impression completely. He seems to be a flippant person.

I think you are angry and sarcastic in what you say, and he may be confused by you. You are making many judgments about him in talking here, like you're reading his mind, but your responses to him are not straightforward, like your second comment in that block. He's hearing what you say, but it's like you expect him to read your mind. You seem to be giving him very mixed signals. He can read your mind.

I'd love to assist, but it seems the more you vent about this person, the more you're upset. So I'm not sure it's helping you.

@Bohemianrelativist Please focus on what you can do to improve your housing situation, and find another position, and move forward. We can support those efforts. It seems you've been through a lot; but dwelling on it will keep you stuck in resentment, which will ultimately only hurt your efforts. Take the time to take care of yourself, so you can move forward again. We care, we really do! But let us help you take care of you, and to move

forward.

@quid >:{

Hello, @AlexanderGruber. But your mobile phone might have signed you in so your not here. At least a hello is harmless.

@amWhy hi there. Really me this time.

@AlexanderGruber :-)

catching up on this chat history. Looks like we've got some new people here?

i don't believe it. i think his phone has developed a sense of humor.

@leslietownes Hah!

@AlexanderGruber Recently, yes.

maybe it picked one up from its manufacturer, who certainly designed a joke of a phone

@AlexanderGruber Hahaha!

Any of you read of the school shooting in Michigan?

yes

Not to mention the concern about omicron.

@leslietownes What was up with the parents? They are now arrested as well.

@amWhy Heard about that. Pretty awful situation overall.

i don't know. weird to see that they're apparently being prosecuted.

@AlexanderGruber Indeed. I learned today that the school brought the parents in for a conference with them, the school, and the shooter, earlier on the same day of the shooting, given ample concern from the staff at the school;

this is incredibly rare, despite so much of the usual rhetoric being about the so called 'responsible gun owner'

@leslietownes Did you read that they bought the gun for their son as an early Christmas present, and when the student was found searching for information on information, by a teacher, and parents were called, the mother responded "I'm not mad, honey" to the son. "You just need to learn how to hide such things better". And after being brought to school for a conference, the morning of the shooting, refused to authorize search of his backpack, or to take him home and get him help! So he remained

at school, went to the bathroom, and came out to kill other students.

Indeed, this is a rare charge. No doubt.

"for information on ammunition for his gun"...

@leslie It seems to me that at the very least, the parents were incredibly negligent and/or in denial. Don't know if it's involuntary manslaughter.

By the way, I hate the term manslaughter. What about womanslaughter, or childslaughter? That term needs to go.

yes, everyone should be included in the slaughter.

Everyone is free to speak, @leslie, @AlexanderGruber. I did not intend to dominate here.

@leslietownes ;P

it would be enough to call it homicide, or unintentional homicide. although i imagine some are so prescriptive that even "homicide" is seen as impermissible.

i think the model penal code, which is not law anywhere but is sometimes adopted in part by the states, still uses 'manslaughter,' which is a little weird. it tends to be more modern than the states.

whoever wants to change this has a good up-to-50-state legislative project ahead of them. good luck.

Indeed.

Why Omicron? We haven't yet had a Gamma variant, etc., etc. Or there were but they died off quickly

@amWhy I think the kid was shopping for ammunition on his phone, which is what she told him not to get caught about. What worries me more is she texted him "don't do it" or something like that around the time of the shooting which makes me think she knew what he was planning and sent him back anyhow.

@AlexanderGruber Yes. That happened the day before the shooting, searching for ammunition, but the following day, a teacher found a drawing of a gun, with a victim bleeding on his desk, which precipitated the parent conference with student at the school.

i assume the prosecutors know what they're doing. a lot of states have something resembling criminal negligence, which you can charge even if there's no death at all. i don't know michigan law on this.

@AlexanderGruber But yes, the parents dropped the ball on this.

whatever the standard is, very rare to see any form of criminal liability potentially extend to parents.

empirically speaking.

@leslietownes might be a good precedent to set

@leslietownes I understand.

@AlexanderGruber Indeed.

yeah, i'm fine with this.

i think this type of legislation would actually be palatable for at least some people in the gun lobby. gun nuts always imagine that they're the responsible ones, and see the problem as bad apples ruining it for everybody. some of them would be fine with high penalties for stuff like this.

@leslietownes True.

@AlexanderGruber I haven't had a chance to talk with you about the Christmas Parade in a "suburb of Milwaukee WI" which is Waukesha, the town I grew up in, in WI.

I won't go into details, just that a man in an SUV crashed through barricades for the "Christmas Parade" route, to kill five participants in the parade, on scene, injuring 50. One of the critically injured, a 5 year-old boy, later died from his injuries.

But, now perhaps I should focus on good news? Any good news immediately coming to one's mind?

@leslie Now's the time to boast about the weather in CA! :-)

Chris Cuomo has been fired from CNN, due to his involvement in supporting and advising his brother (former gov of NY). Just caught that.
