ESFP here I love science lol. I like to watch Neil Degrasse (lol its like Degrassi) Tyson videos and drink homogenous mixtures of red bull and jagermeßter. See what I did there? Bazinga!!

psychology is a pseudoscience so yes

The mating patterns of non-human species are developed due to their ecological niches. No other species can develop a good analogy because no other animal has the same ecological niche or breeding pattern as humans. Parallels can be made, but only in closely related species (either directly related, or related mating habits ie large groups living together, pair bonding, etc)

Humans are not lizards and do not follow lizard sex-types for fucks sake.

>>7632860
>>7632868

I'm aware, but parallels can be drawn (with a bit of imagination). Reds remind me of alpha male sorts with strong urges for power and "Hoe's". This is probably due to the nature of testosterone which is present in both species, and more apparent on both human and lizard sides of the parallels.

The blue is the social norm of most civilizations, and the craving for a strong connection is very human.

The orange reminds me a the archetypical dashing romantic man who never could settle down

fuck yes!! i fucking love science!!! haha! everyday I hurry to finish my homework so I can come on /sci/ and talk about bill nye :) I love you OPi
btw I'm a grill

> NASA shows that there is zero global warming
> le science meme guy with vinegar and baking soda disagrees.
Yeah, nah. I think I'll trust NASA before media monkeys.

>>7631962
LOL! You're just upset because Bill Nye is like totally way cooler than you will ever be :P

2: Levitation / Propulsion

In all the Hyperloop designs available out there and the further reports & analyses that cover the original white paper by Elon Musk, the compressor and the subsequent air bearing system is the design imperative. The piston effect which occurs within an enclosed tube is one of the main challenges a train speeding near 1 Mach would face, hence Musk proposes a compressor which sucks in the air that accumulates at the front of the train. This air is passed through a compressor, and thus sent to the air bearings that provide the levitation, the end nozzle that is the propulsion and the life support systems of the passengers inside.

Our proposed solution is to employ a combo magnetic - air bearing system. Air bearings are very experimental and certainly not employed at the speeds of proposed Hyperloop model, while Maglevs are discouraged by Musk for being too expensive. Hence, by utilizing a firm that's been provided by the competition, we're using a cheaper hover engine, that provides levitation, thrust and braking in addition to the air bearing system that comes with the original design.

The air bearing, due to the constraints in the available tube diameter, will be situated around the guidance rail, thus providing attitude support during turns as well, asides allowing the pod to slide over the rail.

3. Chassis

The chassis will be mainly derived from commercially available Maglev structural designs, that have the following structural characteristicL:
>1) as light as possible,
>2) enough degrees of freedom,
>3) special mechanically-braking mode
>4) unique lateral load way
>5) vehicles fall on rail to slide under emergency

The chassis will be fitted with linear braking systems, pressurized air channels for the air bearings, and hover engines.

The track curve can determine the instantaneous position of the bogie, then the relative positions between bogies, bogie and second suspension system and car bodies by connection relationship and the absolute spatial positions of all parts, all of which only involve the deduction of geometric relationships.

thanks based nasa
I had lost hope in them. But now... I'm in love.

>>7628189
anything that focuses purely on innovation and not at all on evidence

Anything that doesn't have an integral in it.

>>7628189
Retarded shit based in speculation without a deep understanding of the concepts behind it.
It is the trivialization of the knowledge, now you can find assholes doing degrees that are more interested in share memes than spend their time in real study.

Duude.. There won't be any news atleast until january why the fuck are you making these threads ? Since there is nothing to talk about, the thread gets populated by /x/ and ayylmaologists

>the thread gets populated by /x/ and ayylmaologists
Shhhhh.... These are containment threads.
It keeps /x/ busy while the real /sci/entists are busy discussing why free will can't exist, whether 0.999... = 1, brain uploads, and order of precedence in 6/3*2.

So that you go to: http://www.planethunters.org/
and contribute to science

You think you're intelligent or something ?

>>7591879
Of course I'm intelligent, I can abstract universals from particular sense data, e.g. I can abstract the universal "chair" from this object appearing in my vision. This requires intelligence.

>>7591905

And a computer can do that too. Egos like this aren't suited for science.

>>7591538
t-test
what confidence?

>>7591547
Sorry, forgot to include: 95% confidence

>>7591538
>>7591547
So t = 46.3-46.5/( (.7)/(sqrt(20))

You get a t-value

Df = 19
and if confidence is 95%

a = .975

If |t|>p value in table, reject the null

Because they are mortal.

Also pesticides

Varroa & neonicotinoids.

Soviet work camps

No where. Nothing Special will.

You would be bitching about space-industrial complex and how we should spend that money on combating terrorists instead.

>>7590977
Fuck that, where's the recipe for that bread OP?

>>7591013
no idea man

Try the library idiot

a bag of sand, a plate and a lithium battery

>>7590946

I know that, but why would those be combined in a fridge?

>>7590937
Sand or fertilizer, potentially a grass-seed (since the bag is green, advertising purposes -- bad screen at the moment so can't get a closer look) and fertilizer mixture. The next is a 1.3 Ah, Lithium battery on top of what appears to be a cheap ceramic plate.

Never tested it, but I heard you can get rid of a N.A.R.B (no apparent reason boner) pretty quickly by flexing a large muscle like your quadriceps, gastrocnemius, or buttocks for as long as possible.

Adding a pinch of salt to your coffee prevents the bitter compounds in the coffee from binding properly to your tastebuds, reducing the overall bitterness of the brew.

This book has some really fucking cool science behind using physiochemical properties and techniques to change how food tastes, feels, and looks. It also has an entire third of the book dedicated to debunking and/or confirming culinary myths.

My personal favorite goes something like this: Everyone knows that putting lemon on vegetables and non-citrus fruits prevents oxidation. But why? Most people go be the axiom "because it's acidic", but is acidity the actual reason for the prevention of oxidation?

Turns out no.

Some dude at some fancy french biochemistry institute did a really simple experiment: He cut 3 avocados in half. One the first, he basted DI water. The second, lemon juice. These served as his positive and negative controls. Next, he diluted water with acetic acid until he created a vinegar that matched the pH of lemon juice, and basted onto the third. On the fifth, he basted a solution of sodium bicarbonate in water to serve as his base. So, logic would go that if acidity reduces the rate of oxidation, then basicity would increase oxidation rate. On the sixth and final half, he crushed up a vitamin C tablet from the pharmacy in water, and basted it on.

He graded the rate of oxidation based on area of browning and time intervals of like 10 minutes I think for 2 hours.

The results: The only two halves that had reduced oxidation rates were the lemon juice, and the Vitamin C (ascorbic acid). So, it is not the acidity (in terms of pH) that reduces oxidation; it was the ascorbic acid. My father likes to argue semantics and say "well its still the acid", I just face palm and tell him to go sell his cars. It's not really a "hack", but it's a neat bit of info.

/Adderall rant over

>>7590823
Said differently, did we evolve language, or did our brains simply by chance have the faculties needed to produce the behaviour of language?

>>7590823
Do you even know what a DNA is?

>>7590835
No. If you are smarter than me could you help me figure out why this is a stupid question so I can try and ask what I mean?
