Engineer: The glass is twice as big as it needs to be.
- 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.
  
  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.
  
  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.
- Backyard tinkerer and wannabe Engineer: I'll just use this glass jar I used to drain some gas as the thing to drink my water now ..... this is water right?
- Not if you need to stir it.
- a true engineer gets a mindworm and precisely calculates and trials the minimum size of glass needed to contain the liquid without spilling
- Mechanic: The glass is not leaking. Returned to service.

My mother in-law is a lab scientist. She says this is accurate.
- You don't even know the half of it
  
  I think they do know 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
- But what if I pour vacuum into the beaker?
  
  I'd like a bagel with everything
  
  Then it would be full of dust bunnies
  
  Full of vacuum
- Hopefully, otherwise it may end bad: https://what-if.xkcd.com/6/
- for some reason that was never acceptable answer when I gave it. i think they were just jealous they didn't think 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
  Pedant
  
  technically correct, which is the best kind of correct

Realist: who’s cleaning all these glasses?
- Fucking real

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.
(version 3)
- Does this work?
  If you looped it or created a doubly linked list what would happen?
  
  Either perpetual motion, or a very wet desk, no in-between
  
  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!

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

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!
- Sticky, Silky, and Danger Syrup! Sounds like a cool lab.
- 16M HNO3? Wouldn't that be fuming?
  
  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.

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.

(I have no idea what I'm saying lol)
- Scientific paper writer

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%

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.
- It's a thought experiment with a static partly filled glass of water, it isn't in a process. It is intended to show the different ways of describing the amount of water.

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
- Why do you keep vinegar in the fridge? I keep the gallon jug in a cupboard and smaller container just on the counter
  
  Why do you keep vinegar in the fridge?
  Imagine the trouble if it rots!
- Loool, and do you keep sodium cyanide in your spice cabinet too?
  
  Probably a good idea for the winter since fresh apricot seeds would be scarcer. j/k
- How much vinegar do you use????
  
  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)

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

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.

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

Topologist: that is a plate

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.

Engineer: the glass is twice as big as in needs to be.

Realist: Guys, I think this is piss.
- I keep piss bottles in my solvent cabinet

Turns out it was FOOF.

People who call themselves realist tend to be pessimists.

Literalist: The volume of the container is ~50% water.
- What's in the uncharacterized volume?
- There's no approximation in literalism! If that glass isn't a beaker, you find the nearest means to measure and.go to town. I'll accept 1 thumb length of water to ait at 1 thumb length minus the thickness of a bank card and driver's licence..
