Engineer: The glass is twice as big as it needs to be.

[–] flamingo_pinyata@sopuli.xyz 79 points 2 weeks ago (2 children)

Bad Engineer: The glass is twice as big as it needs to be.
Good Engineer: The glass is 66% full with a 25% safety margin.

[–] MyTurtleSwimsUpsideDown@fedia.io 45 points 2 weeks ago (1 children)

This glass has a safety factor of 2

Re: good engineer: this is the thing that frustrates me amount marketing/labeling for travel mugs or cookware; the listed capacity is the absolute brim capacity not the practical capacity. Want to put 16 oz in a 16 oz mug you’re gonna have to sip 3 ounces out first in order to put the lid on. Want to serve 2 qt soup? Gotta use the 3 qt pot.

Yes!! So unbelievably annoying. Okay. Thank you. The total volume of this cylinder is 473ml. What the fuck can I use this for?! What I want you to tell me: total volume and total practical volume. Dumb af

Real engineer: it's full. Approximately 50% water, and the rest air.

"The glass was built to the wrong specifications"

Glass functioning as intended. Any deficiencies that arise are due to the failure of the customer to provide appropriate design parameters.

[–] phdepressed@sh.itjust.works 6 points 2 weeks ago

Not if you need to stir it.

My mother in-law is a lab scientist. She says this is accurate.

You don't even know the half of it

The beaker is always full, when it's half full of water, it is also at the same time half full of air. THE GLASS IS ALWAYS FULL

[–] dvlsg@lemmy.world 13 points 2 weeks ago (3 children)

But what if I pour vacuum into the beaker?

I'd like a bagel with everything

Opportunistic Lab Intern:

“While you’re all debating if it’s half full or half empty I drank it. Now it’s empty.”

Ah, it's this time of the year again. linked-list (version 3)

[–] wise_pancake@lemmy.ca 4 points 2 weeks ago (2 children)

Does this work?

If you looped it or created a doubly linked list what would happen?

[–] zalgotext@sh.itjust.works 15 points 2 weeks ago

Either perpetual motion, or a very wet desk, no in-between

[–] reinei@lemmy.world 9 points 2 weeks ago (1 children)

This particular version wouldn't work because the exit point is not lower than the entry point so after a possible initial splash from the first glass the outside air would rush in from the top of the straw and thus push down the water to its own level again...

So sadly no singly linked lists without stairs!

My lab is pretty easy to guess, it's either 18 MΩ water, 100% EtOH, or 16M HNO3. 66% chance it's not acutely dangerous, not bad for a lab!

[–] Rubisco@slrpnk.net 6 points 2 weeks ago

Sticky, Silky, and Danger Syrup! Sounds like a cool lab.

[–] MataVatnik@lemmy.world 4 points 2 weeks ago (1 children)

16M HNO3? Wouldn't that be fuming?

[–] Kroxx@lemm.ee 8 points 2 weeks ago

It's technically like 15.7M , it's the highest concentration you can get before you hit fuming (~70wt% iirc). Although anything you do with it after makes it fume like crazy anyway.

[–] VivianRixia@piefed.social 12 points 2 weeks ago

Scientist Russian Roulette: Drink the mystery breaker. They all have water, except for one that's hydroflouric acid.

[–] FatTony@lemm.ee 9 points 2 weeks ago (1 children)

I thought the half full, half empty thing. Was about the flow of water. If you're emptying the glass, at some point the glass will be half empty. If you fill the glass, at one point the glass will be half full.

Ahh found that label!:

99.985% Pure.

Nitrogen (N₂): 39%

Oxygen (O₂): 10.5%

Argon (Ar): 0.465%

Carbon dioxide (CO₂): 0.02%

Water (H₂O): 50%

After a long romp, a fairly new g/f went into my kitchen, grabbed a 1 gal bottle of white vinegar from the fridge, poured herself a glass and tried to chugged it while I was still in bed recovering. -She had the nerve to think I tried to poison her (for half a minute)!

Read and use labels. lol

[–] oxideseven@lemmy.ca 10 points 2 weeks ago (1 children)

Why do you keep vinegar in the fridge? I keep the gallon jug in a cupboard and smaller container just on the counter

[–] marcos@lemmy.world 6 points 2 weeks ago (2 children)

Why do you keep vinegar in the fridge?

Imagine the trouble if it rots!

How much vinegar do you use????

[–] madthumbs@lemmy.world 8 points 2 weeks ago (2 children)

It's good for toilet bowl cleaner, weed killer (including poison ivy), wiping down a large cutting board (not used for meat), fruit and veg wash, descaling / removing water marks, rainbow stains or chrome / nickel residue in pans, it softens fabrics if added to laundry, is used for mayonnaise, salad dressings, sticky rice, deodorizing, and combined with baking soda has been the only thing that worked for a clogged drain. It's also cheap in the gallon size and practically free for people on SNAP. (a lot)

[–] zalgotext@sh.itjust.works 9 points 2 weeks ago (1 children)

That's a lot of good reasons for keeping a large quantity of vinegar, but I think we're still mystified as to why you keep it in the fridge

[–] madthumbs@lemmy.world 7 points 2 weeks ago (1 children)

I don't anymore, but.. I liked it cold for some applications like canned spinach (cools that steaming pile of mushy green down). If I were to make things like mayonnaise with it, it keeps the ingredients in the safe temperature zone or gets them there faster.

That beaker does not look half full to me. Many like 1/3rd full, or at least somewhere between that and half full.

100% Full with 50% volume occupied by Dihydrogen monoxide molecules and 50% volume occupied by a mixture of molecules in gas form, colloquially refer as "air", which contains, according to the statistical data recorded by analyzing the gas molecules in the air in the Earth's Atmosphere, 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other trace gases.

Scientific paper writer

Engineer: the glass is underutilized/over-sized

Management: Lets hire a consultant to investigate the value proposition of downsizing glasses and discuss the results over a company expensed dinner.

[–] mexicancartel@lemmy.dbzer0.com 5 points 2 weeks ago

I just watched this so i have to post here https://youtu.be/0EytSWiKrFg

[–] CascadianGiraffe@lemmy.world 4 points 2 weeks ago

It's not 'is the glass half full or half empty'.

The question is 'why is the glass?'

Once you know this, the first question is easy to answer.

[–] hOrni@lemmy.world 4 points 2 weeks ago (1 children)

Realist: Guys, I think this is piss.

[–] MataVatnik@lemmy.world 4 points 2 weeks ago

I keep piss bottles in my solvent cabinet
