Is a PhD in engineering worth 5 years careerwise? I'm assuming nobody actually pays money for a PhD
6 posts and 1 images submitted.

>>9121717
Academia and government research wants PhDs. If you want to go into industry then it completely depends on the sub-field. Example: companies implementing CFD solutions desperately need PhD's because only they understand the state of the art and it proper applications. A code monkey with a BS isn't going to be able to integrate new RANS methods without fucking it up.

Im working in industry now and the upper echelon of engineers at my company all have PhDs. Many go into academia because it's a far easier job and lifestyle

Really? Are they non-tenure track? Because getting tenure and basically working on commission (salary a function of grant money pulled) seemed hella time consuming for my profs.

Is that Ithkuil?
https://en.wikipedia.org/wiki/Ithkuil
http://www.ithkuil.net/
>Ithkuil is an experimental constructed language created by John Quijada,[1] designed to express deeper levels of human cognition briefly yet overtly and clearly, particularly with regard to human categorization. Presented as a cross between an a priori philosophical and a logical language striving to minimize the ambiguities and semantic vagueness found in natural human languages,[2] Ithkuil is notable for its grammatical complexity and extensive phoneme inventory, the latter being simplified in the final version of the language.
>>
>>9121198
I would say very slow since it has a too complex structure (phonology, grammar & writing system).
The letters also have too similar shapes, so they can be easily be mistaken/confused.
>>
Yeah, I thought about trying to learn it, but I don't really know where to start. It seems pretty daunting just to say one sentence.

So I was exploring in a game called Space Engine, and I found a planet that has life. I was wondering with all the data it tells me, could humans live on this planet without the need of a space suit or breather? I'm not to well read on breathable atmosphere, but I think they could.

CO2 is the molecule which the body's chemoreceptors monitor to determine whether or not the body is suffocating

ignoring the other physiological problems from that much CO2, no, you cannot breathe on this planet

>>9120469
>"not well read"
>has a level of knowledge worse than a middle schooler
>>
>>9120477

i'm this anon. continuing reasons why you can't breathe on this planet: at 1 atm of pressure, you need an air composition that's at least 19.5% O2 to not start having any physical impairments during day-to-day activities. the O2 on this planet is insufficient as such.

also, that trace of SO2? NIOSH says 100 ppm of SO2 is an immediate danger (1: it's a toxic gas, 2: it smells fucking awful)

so yeah. this planet smells like shit and you start choking to death the moment you breathe in. however, the pressure is very tolerable. you could probably survive if you just wear a face mask and SCBA

I'm going to use three pairs of sunglasses to view the final phase of the solar eclipse. There will be 15% of the Sun still showing when this occurs because shitty location + university. Will I go blind? (2 minute duration)
11 posts and 1 images submitted.
>>
yes, you will go blind. your sunglasses will cut the light down by about 15-fold. you need a filter that cuts the light down by 500,000-fold.

enjoy your legal blindness
>>
>>9119219
Hey OP here, this is not the reaffirming answer that I desired.
>>
>>9119230
You need a filter that cuts out 99.997% of incoming light. You risk burning out the cells in your fovea. You might wake up tomorrow being able to see nothing but broad fuzzy shapes.

Do. Not. Fuck. Around. With. The. Sun.

I've been irresponsible in the past welding just with sunglasses and all I got was a terrible case of arc eye for a few days why should watching the eclipse with sunglasses be any different?

Not even trolling.

its not different until the eclipse is 100% then its like looking at a full moon

At least for games, go cold turkey. When you want to reinstall a game, think of how much time you used to spend and what you got in real life when you stoppped(i.e. nothing), maybe just some (You)s on /vg/. And just don't do it. No exceptions.

>>9118742
Being addicted to games is real. I spent thousands of hours on paradox autism simulators, that I won't get back.
>>
>>9118758
You act as if those hours could have been spent doing more. People have their hobbies. Would you say someone interested in music wasted thousands of hours they wont get back on studying music. No you wouldn't. What seperates the two hobbies?

You shouldn't drink raw blood for the same reason you shouldn't eat raw meat. You're likely to get foodborn illness.

Cannibals have reported that human flesh tastes like veal so maybe try to get some calve blood.

Panspermia (from Greek πᾶν (pan), meaning 'all', and σπέρμα (sperma), meaning 'seed') is the hypothesis that life exists throughout the Universe, distributed by meteoroids, asteroids, comets,[1] planetoids,[2] and also by spacecraft in the form of unintended contamination by microorganisms.[3][4]

The closer ecosystems are, the more probable it becomes, imo.
I'm not convinced about the universal "pan" stuff, though.
>>
>>9118323
It makes a lot of sense to me: the initial steps of life, like getting some simple self-replicating protein are fairly unlikely, so the huge surface area of space dust helps that along, then the dust plants these proteins on Earth (or some other planet) where they then evolve into complex life. That is much more likely than proteins themselves appearing on Earth.
>>
Panspermia merely delays the question of where life comes from. Even if it's found microscopically throughout the universe, that still doesn't doesn't tell us WHERE it comes from.

Going to bed slightly hungry vs eating something light (let's say a banana or a yoghurt) before bed, which is better?

Better how? It depends on what you want to acheive
>>
>>9118280
Hungry. Don't eat anything within the 5 hours before you go to bed. Only liquid should be water.
>>
>>9118300
Better for quality of sleep and/or time it takes to fall asleep.
