new prof for my undergraduate mat sci class actually spent half the lecture going over basic periodic table things

legorhin Aug 25, 2020 2:42 PM general

no chem prereq?

legorhin Aug 25, 2020 2:42 PM general

or just review because its very important as a basis?

Lute Aug 25, 2020 2:43 PM general

I think he's just new and is trying to review but doesn't really know what needs to be reviewed

Lute Aug 25, 2020 2:44 PM general

it's a core class for my major so anyone taking it has already had basic chem classes

Spooky Phijkchu Aug 25, 2020 2:44 PM general

Senior level class, learning the periodic table

Spooky Phijkchu Aug 25, 2020 2:44 PM general

amazing

Lute Aug 25, 2020 2:44 PM general

oh hey it's new stuff

legorhin Aug 25, 2020 2:47 PM general

was it covering atomic masses and what the columns mean?

Lute Aug 25, 2020 2:47 PM general

it was kinda just like ehat all the numbers mean

Lute Aug 25, 2020 2:48 PM general

like defining ionization energy

Lute Aug 25, 2020 2:48 PM general

atomic mass

Lute Aug 25, 2020 2:48 PM general

number

Lute Aug 25, 2020 2:48 PM general

that kind of thing

legorhin Aug 25, 2020 2:48 PM general

so sophomore high school chem stuff

Lute Aug 25, 2020 2:48 PM general

he pointed out some things about certain elements too

Dolfin Aug 25, 2020 2:49 PM general

10th grade they said hydrogen was 1.01 g

Dolfin Aug 25, 2020 2:49 PM general

12th in ap chem they told me it was actually 1.008

Dolfin Aug 25, 2020 2:49 PM general

Now they tell me it’s actually 1.00794

Dolfin Aug 25, 2020 2:49 PM general

How do I know that’s the real truth

Dolfin Aug 25, 2020 2:50 PM general

The government is hiding hydrogen mass from us

legorhin Aug 25, 2020 2:50 PM general

the trick is all are correct

Lute Aug 25, 2020 2:50 PM general

the true mass of hydrogen is 2

legorhin Aug 25, 2020 2:50 PM general

deuterium pog

Lute Aug 25, 2020 2:51 PM general

can hydrogen have 2 neutrons, I can't remember

legorhin Aug 25, 2020 2:51 PM general

tritium

Lute Aug 25, 2020 2:51 PM general

doubt it's very stable

legorhin Aug 25, 2020 2:51 PM general

its just extremely rare

Dolfin Aug 25, 2020 2:53 PM general

I love that no one in my college cares about in up stair wells and down stair wells

legorhin Aug 25, 2020 2:53 PM general

why does the chem e not know the hydrogen isotopes?

Dolfin Aug 25, 2020 2:53 PM general

Hydrogen is a lie made up by the Jews

Dolfin Aug 25, 2020 2:53 PM general

It’s actually chaidrogen

Lute Aug 25, 2020 2:54 PM general

I remember deuterium being brought up, we just haven't talked much about it or tritium

legorhin Aug 25, 2020 2:55 PM general

bopit do you know about the 15 different types of water ice?

Dolfin Aug 25, 2020 2:55 PM general

Who cares

legorhin Aug 25, 2020 2:55 PM general

its cool chemistry

Dolfin Aug 25, 2020 2:55 PM general

Ha cool chemistry

Dolfin Aug 25, 2020 2:55 PM general

Ice

Dolfin Aug 25, 2020 2:55 PM general

Cool

Dolfin Aug 25, 2020 2:55 PM general

Funny

Dolfin Aug 25, 2020 2:55 PM general

Meme

legorhin Aug 25, 2020 2:55 PM general

oh its actually 18

Dolfin Aug 25, 2020 2:56 PM general

ITS LEGAL

Dolfin Aug 25, 2020 2:56 PM general

POGGERS

Lute Aug 25, 2020 2:56 PM general

crystaline phases? no not really

legorhin Aug 25, 2020 2:56 PM general

https://en.m.wikipedia.org/wiki/Ice#Physical_properties

Ice

Ice is water frozen into a solid state. Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Su...

Lute Aug 25, 2020 2:56 PM general

if I was going to learn anything about crystal structure it would have been in inorganic probably

legorhin Aug 25, 2020 2:57 PM general

i think i learned of this stuff in thermo

Lute Aug 25, 2020 2:57 PM general

and my inorganic prof was a useless individual

legorhin Aug 25, 2020 2:58 PM general

so you didnt see the phase diagram of water in thermodynamics with some of the different ice types marked on it

Lute Aug 25, 2020 2:59 PM general

Lute Aug 25, 2020 3:00 PM general

this is what our phase diagram looked like

legorhin Aug 25, 2020 3:00 PM general

Lute Aug 25, 2020 3:01 PM general

yes that one too

Lute Aug 25, 2020 3:01 PM general

never talked about the 15-18 different ices

Lute Aug 25, 2020 3:02 PM general

we mostly cared about liquids and gases

legorhin Aug 25, 2020 3:03 PM general

because all thermo cares about is carnot cycles

Lute Aug 25, 2020 3:04 PM general

yeah we did a lot of cycles in thermo

Lute Aug 25, 2020 3:04 PM general

dunno if it was just the carnot cycle

Lute Aug 25, 2020 3:04 PM general

can't remember the name

legorhin Aug 25, 2020 3:04 PM general

there are a bunch but carnot is the basic one iirc

Lute Aug 25, 2020 3:05 PM general

might have been the rankine cycle

Lute Aug 25, 2020 3:05 PM general

also did whatever the refrigerator cycle is a bit

Phijkchu_Pikachu Aug 25, 2020 3:08 PM general

my favorite phase diagram for water is the one that includes all the different ways ice forms

Lute Aug 25, 2020 3:14 PM general

I'm a statistic pog

Spooky Phijkchu Aug 25, 2020 3:38 PM general

Well, RIP my AskFM account

Spooky Phijkchu Aug 25, 2020 3:38 PM general

I guess Pasword123 wasn't secure

Spooky Phijkchu Aug 25, 2020 3:38 PM general

lmao

Spooky Phijkchu Aug 25, 2020 3:39 PM general

welp... goodbye AskFM I guess

Dolfin Aug 25, 2020 3:39 PM general

why would someone know all of those off hand

Dolfin Aug 25, 2020 3:39 PM general

at least 1 and 4

Spooky Phijkchu Aug 25, 2020 3:39 PM general

all of them honestly

Dolfin Aug 25, 2020 3:40 PM general

the one i would know is email

Dolfin Aug 25, 2020 3:40 PM general

thats it

Spooky Phijkchu Aug 25, 2020 3:40 PM general

idk, I can't say for sure if this email is what I even created it with

Spooky Phijkchu Aug 25, 2020 3:40 PM general

or if I changed it at some point

Spooky Phijkchu Aug 25, 2020 3:40 PM general

not like I've used it in the last 5 years

Spooky Phijkchu Aug 25, 2020 3:40 PM general

it's just funny
