What shit tier class was this? Also don't expect the first week to have anything useful, don't expect year 1 to be any more than highschool 2.0 unless you actually attend a good university with good programs

>>9941572
maybe you should have thought about that before you entered the women's studies program at femlib university you dumb shitposter.

Calculate the safe are
Calculate the not-safe area
If sa > n-sa you toss the coin

>>9941516
But payback in 9x the loss so you can still get a good return even if the safe area is small, it would just be more work to calculate what that limit is

>>9941510
Expected value is positive, which is probably what your homework expects you to say.

>>9941516
lol how is the Riemann hypothesis even hard dude just figure out where the zeroes are

I don't bother because winning 90 cents is not worth bothering with.

Now I DO buy lottery tickets from time to time. The odds are, og course, terrible -- but what I put at risk, I'll never miss, and if I DO happen to win it'll be life-changing.

Matter IS energy, though.

It's all relative to your needs. The biggest issue with these kinds of things is not that they are inherently unhealthy, but that people discount them as being so healthy that they've earned the right to make other unhealthy choices as if this somehow balances out as neutral.

>>9941419
I get that, but I'm saying is it healthy to drink? The sugar content is high, but since it's natural fruit sugar, does that make it ok despite it being 64 grams? Or should I avoid it?
>>9941426
So you're saying I should probably avoid it?

>>9941426
I think it might help if we go back to the core reason why sugars are considered unhealthy.

They make you fat because of high calories, they rot your teeth, and they can cause diabetes. Fruit smoothies can do all of those things just as easily with it's "natural" sugar as a coke can with it's added sugar

>>9941431
my point is that there's no difference. Sugar is sugar is sugar. Sure there are some slight differences between fructose and sucrose but they're pretty much indistinguishable in your body.

A healthy diet can contain sugars but just be aware that these fruit smoothies are pretty much the same thing as a milkshake

>>9941431
>The sugar content is high, but since it's natural fruit sugar, does that make it ok
No, fruit is okay because it's packed with so much stuff that your body needs to break down, which is not the case in smoothies or fruit juice.
Even then, fruit isn't all that healthy: it's got lots of nutrients, but it's so sweet that its consumption should be somewhat limited.

Top 5 reasons we are not going to be alright:
1: Climate change 2: Peak oil 3: getting close to super intelligent AI 4: Interstellar travel will never be feasable, so humanity will be stuck on this rock forever 5: tfw no gf

i do not give a shit, i would be pleased if either people survive or AI. complete desolation would be meh but thats probably it. thats science for you brahs xddddddddddddddddd

no

I will

no boomers, AI, climate change, degenerates, etc.

the american healthcare system was designed to wring as much money as possible from insurance companies. Any other side effects, like curing the patient, are just incidental.

I find it hard to believe actual MDs use 4chan. Maybe med students but even then, doubtful.

Believe it, the future is now, soon enough as this generation ages, no matter how many NEETs and incels that includes, they will take over political offices and government jobs, much the same way memes became mainstream because 12 year olds started to grow up

1. No demand. No, nerds who watched to much scifi are not a market
2. Dangerous to other people when used in populated areas. No way they will be allowed near cities or villages, we do not even allow drones over a certain size in cities because they can kill people if they crash or lose parts.

Same reasons why we do not have flying cars: It's not that we can't have them, we just don't need them.

>>9941489

It's the basis for ion engines which NASA uses in space. They aren't really usable in atmosphere due to the lack of a suitable power source.

>>9941536

First of all it's hard to know exactly how efficient nuclear would be since attempts to examine this in depth were ended in the mid-70s. Secondly the raw power density of uranium is greater than jet fuel, giving a theoretically larger electrical power source which could drive turbines or propellers (or ion engines) at higher speeds than their fossil fuel counterparts.

>>9941562

We don't have flying cars because there's no place to park them since getting a legal urban helipad built is a massive bitch and requires a lot of paperwork. The FAA's stringent pilot licensing program (including mandatory health checks) does not help. If getting a helicopter license only cost $100 and could be done in a few weekends, more people would get one.

>>9941564
>getting my hopes up with shitty ion wind lifters

I thought there was an actual development in that field or some shit.

Maybe one day we can brute force it.

>>9941272
>>9941319
>>9941328
>>9941338
It barely does anything simply because there's not enough power or power density to lift enough weight or produce enough force to properly maneuver in the ways needed for it to be useful. This is because it is horrifically inefficient in its design. Why? Because people want a "hoverbike" design for some tarded reason.

>>9941562
>Same reasons why we do not have flying cars

We have them. They are called, "helicopters," and, "aeroplanes".

Were you doing anything while drinking?
Where were you drinking? at a party? With a friend? Alone?
How much did you drink? Just a buzz, or did you get pissed? Somewhere in between?
What was your depressive state before drinking, compared to days after when the depression returned? Better? Worse?
Are you inclined to drink more to numb the pain? (This can very easily lead to alcoholism as your body develops a tolerance to it.)

Everyone knows about alcohol. It doesn't make you feel better, it just makes you feel nothing.

>>9941233
>Were you doing anything while drinking?
I was just chilling with a friend and watching TV in my relatives small apartment.

>How much did you drink?

Quite a lot(dangerous to stand without concentration), a beer more would've been too much and unenjoyable.

>What was your depressive state before drinking compared to days after when the depression returned?

Before drinking I was at 3/10 (lower=worse). The week and a half following I was at a steady 8.5/10. Now I am at a stable 3.5-4/10 so slightly better than before drinking but only slightly.

>Are you more inclined to drink more to numb the pain?

No.

>Everybody knows about alcohol. It doesn't make you feel better, it just makes you feel nothing.

Going to strongly disagree on that one. I'm not 100% that the alcohol eleviated my depression but assuming it did this is what happened in more detail.

Pre: No interests, no enthusiasm, extremely low drive, bad sleep, social isolation, extreme apathy with the only prevalant feeling is ocassional (1-3 times a week) emptiness.

After: Enthusiasm, started to work out again, started studying, much less apathy, feeling of wanting to talk to friends again, return of interests. A sense of ability to feel and care.

Appreciate your contribution to the discussion Anon.

Not OP but I have a bad habit of taking my work home with me every night unless I have something to drink and I'm really trying to avoid drinking daily but the benefits are excellent and I'm still able to have enough self control that I don't get fucked every night, 3 drinks max. A couple years ago I got fit because lots of people say the exercise helps you drink less but all I found is I still want to drink but also I'm in shape now, so I guess that's a plus, but it didn't really help. Now that I'm in grad school my anxiety is getting worse because I'm in a good lab that publishes a lot and I'm under pressure to get results. Was good for awhile, two pubs, but my current projects I don't even enjoy anymore so it's making it more difficult.

>>9941260
In that case, so long as you enjoy it responsibly and in moderation, there's nothing wrong with it.

I will suggest that, if you do start drinking regularly, take time off once in a while, both to avoid becoming dependent and to see how it's affecting you over the long run. If you barely feel different abstaining, you're good. If life becomes absolutely horrible without it, that's a problem. As bad as you think depression is (from one who knows), alcoholism is far, FAR worse.

>>9941286
Thank you again for the participation as this is very helpful for me.

If I do start drinking I'll probably only need(assuming the same length of efficacy) to drink once a week or even once every two weeks but I am still concerned with the health effects as I am still young.

With that being said the effects of depression are far worse than the effects of occasionally drinks from an academic stand point which is critical to me this year.

Do you think there is any scientific reason for this happening or if this is only coincidental? As I said before, I know ethanol fucks with NMDA but not sure how.

Sound doesn't "move" it creates perturbations what's already there. There is no "wave" aspect to a sound "wave", it's compressions and rarefactions.

>>9941181
there's some possibility it's genetic
that said sleep apnea/discomfort can make sleep more fitful so you need more of it
you can try exercise
jerking off or eating too much seems to make you sleep more too
chronic sleep deprivation will just make you stupid, speaking from personal experience

it's genetic; my biological clock has 4-5 hours of sleepy time and I haven't done anything to induce that

>>9941181
