Are jetpacks actually fucking real now? Is the future happening?

Jetpacks have existed for decades. They just have always sucked. They're likely to continue sucking for the foreseeable future.
>>7655220
I don't know why they're claiming it's the "world's only," rocket packs have been around since the late '50s and even the turbine-powered pack has been done before (Jet Pack International has/had a prototype and was trying to bring it to market for quite some time).
Those look like JetCat model jet engines.
Why does butter take less time to solidify in a refridgerator than it does to liquify at room temperature?
You should read about statistical mechanics.
>>7655167
A basic rule of physics is that temperature is related to how fast molecules are moving. In gas state they're highly erratic, solid they're pretty much stationary. Colder temperatures mean the molecules move around less, therefore are more willing to stay in a solid state.
>>7655222
I didnt ask why a refridgerator makes butter solid
Is it worth getting a flu shot? And how can you better protect yourself against a flu?
-Washing hands
-Dress warm
-Avoid proximity near sick people
Anything else?
Dont rub your eyes. The eyes are the biggest entry point for infection.
The flu this season is mild, but lasts long and is very infectious. Its worth getting a shot if you havent already.
Over here in europe only old/sick people get flu shot.
>>7655158
>Is it worth getting a flu shot?
Yes.
>And how can you better protect yourself against a flu?
See above.
if it was discovered somehow that every electron was a conscious life form and that using them in our electronics was committing genocide of that life form, would it be ethical to continue to use electronics?
Morally, would we all need to become Amish?
>>7655014
When you metabolize, electron transfer occurs
So you'd need to stop metabolizing
Kill yourself

We feed or we are fed upon. There is nothing else.

i just received one of the things in picture in the mail and i noticed something strange. when i touch it, and those bendy rays go towards my finger, my tinnitus changes frequency. when i untouch it, the normal frequency returns. what's happening?
>>7654982
smell your fingers after you touch it
>>7654984
this didnt make me any wiser
>>7654991
what did it smell like?
Can somebody tell me the difference between a lake and a swamp
Swamps are big areas with poor drainage that kind of collect stagnant puddles forever. Lakes are distinct deep bodies of water.
... Is there really a place named titicaca?
>>7654944
>is there really a place named titicaca?
It's one of the biggest, if not the biggest lake in South America, m8
>>7654973
is there any similarly named lake?
I think everyone on /sci/ is retarded.
I believe this to be so due to the inconstant consensus which seems to be built upon a solid base of memes and prejudice.
Some time ago I was looking for a good calculus book when I came to /sci/ for a recommendation.
I had already done online research into the best book and the best option seemed to be a $14 Spivak.
Various anons informed me that the text was high quality but I'd have to be autistic if it were my first time looking into calculus.
I though "oh goodie, I am indeed thoroughly autistic", so I purchased the book along with Modern Calculus and Analytic Geometry by Silverman and Phisics I and II by Halliday and Resnick 3rd Edition.
I am very pleased with my purchases.
A few weeks later I come back onto /sci/ and everyone is in unanimous agreement that Spivak is inferior to both the formerly despised Baby Rudin and Apostol I and II.
I am willing to bet that only 20% have at least a Bsc and the rest of you are just posturing faggots.
I don't have a Bsc myself but, even I can tell that the level of expertise and knowledge here is desperate mimicry at best.

>"oh goodie, I am indeed thoroughly autistic"
It shows.
>>7654895
is that matlab back when it was free?
>>7654898
Why should I?
20yo junior in undergrad working my way to a PhD in bio, eventually. What are the other biologists of /sci/ up to?
>>7654885
are you in the okc area? or is that museum a bigger deal than i think? i'm not smart or anything i don't even belong on this board so i have nothing to share
Sort of. I just took a pic because Halloween, and it's the most biological picture on my phone.
>>7654885
>over 300 skellingtons on display
Wayyy2spokky4me m8
Also, biology is for women and gays
I know this is by no means objective but what might be the evolutionary reason for wanting to cuddle with a member of the opposite sex in this room so badly?
Cold so you'd want body heat, opposite sex because sex, good vantage point while protected on most sides so can relax.
>>7654855
we should have a seperate board for "evolutionary reason" speculation
>>7654862
what is the evolutionary reason for seperate boards for shitposting?
What do you guys think about flat earthers?
https://www.youtube.com/watch?v=h5i_iDyUTCg
This is the video all of them post when cornered and desperately want to convert someone to their religious cult.
>>7654852
Shit thread.
>>7654852
I was cringing at 30 seconds in
I think the only way to show them the curvature of the Earth is to actually stick them in an aircraft and fly high enough but that's be really expensive and they'd probably say that it was a clever simulation or something.
Not really much point arguing with them, there's a huge amount of evidence they're already ignoring so we may as well let them be deluded in their own corner as long as they don't try and convince others that the earth is flat
>>7654852
flat earthers are really just trolls. the whole flat earth thing is a 'debate society' front.
How would you go about calculating the number (approx) of miles of road in
i] Any given city
ii] All cities on the planet?
>>7654830
1/find a way to extract the roads from your picture and represent them with the same width
2/count all the road pixels
3/use scale of map to determine the whole length
>>7654839
Unworkable.
>>7654830
look it up in your handy dandy table of road lengths.

queen on d7 then either advance the pawn or get rid of the knight depending on what black does
black because i just reported you

How do you explain the fact that out of endless possibilities of combinations of arbitrary parameters all of which would lead to nothing in particular, the specific combination of arbitrary parameters that constitute our physical world led to us and all this?
>>7654778
In whatever kind of wasteland exists outside of our universe, there are no physical laws (e.g. of conservation of mass/energy) to bar universes like ours from popping into existence. Of these universes, only the ones which are stable survive, and of these stable universes, only the ones that can support complex intelligent life give rise to the question of their own existence.
>>7654918
>le fancy re-statement of le weak anthropic principle xD
The first sentence is a novel addition however.
>>7654778
Because if it didn't, we wouldn't be here to talk about it. If we're here, it had to be this "combination"
Can someone explain to me what genetics tell us about Europeans and especially Germanic people? I'm not a stormfag by the way
That they are a unique genetic clustering that should be preserved and protected rather than thrown onto the alter of globalism to satisfy some transient neo-Marxist political wetdream.
It tells us Indo-european speakers came to Europe from the mountains of the middle east as picrelated is the distribution of the R1b which is ancestral to all western European R1b.
>>7654782
Is there anything mentionable about people with green eyes? ie, people from around the eurasian mountainous area?

You can't represent the whole of Japanese art with the Edo period alone. Least that's probably when it's from without bothering to look it up.
