>>7632845 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)
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.

Is anybody watching the premier of Bill Nye's new show on Nat Geo. Right now he is taking global warming deniers to task in a hilarious way that is still accessible to the layman. Plus an Arnold Schwarzenegger cameo.
It's been a while I've posted updates and surely a lot have happened meanwhile. We are the Hyperloop Student Competition Team of /sci/, although our team have changed quite a bit - most of our members went away but I got to replace them with others. Anyway, we have a Prelim Briefing Submission coming up and we've pretty much covered our main design features.
I'm here today to do a sanity check - to see if our design ideas are actually valid or not. So before you start saying >he does it for free, let me remind you that this... Comment too long. Click here to view the full text.
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,... Comment too long. Click here to view the full text.
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... Comment too long. Click here to view the full text.
NASA has BTFOd the Intergovernmental Panel on Climate Change's 2013 report saying that Antarctica is melting.
Using altimeters on ESA's European Remote Sensing satellites for the period 1992-2001, and on NASA's Ice, Cloud and land Elevation Satellite for 2003-08, NASA has worked out that Antarctica... Comment too long. Click here to view the full text.
What does /sci/ consider to be pop science? Is it strictly those "sciency" youtube videos that fudge the facts to sound more interesting, or is it anything that isn't written by the guy that discovered whatever he's talking about?
>>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.
That's right, another fucking KIC 8462852 thread, but this time it's different. Instead of just fapping about what we'd if we contact ayy lmao's let's do something useful, let's search for more alien megastructures!
Go to http://www.planethunters.org/ and start searching!
It's the same shit that was used to discover KIC 8462852.
TL;DR let's hunt for ayy lmao's using the internet! http://www.planethunters.org/
>>7623499 >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.
hey /sci/ fags, if the universe wasn't intelligently designed, then how is it intelligible? If the universe was made out of nothing like you say . . . then there is no reason why it should have an intelligible structure anywhere.
>>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.
>>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.
Let's have a /sci/ lifehack thread. Can be anything from math tricks, laboratory techniques from all flavours of science, or just using simple chemistry or physics to make life that much easier.
>>Take 90% isopropyl OH from the drug store (or reagent grade if you can get it), make a solution of 60% Isoprop-OH and 40% water. Put that shit in an empty spray bottle, and use it to melt even the thickest of ice on windshields in the morning. Keep it with your antifreeze or where you store that kind of crap, and never worry about scraping ice... Comment too long. Click here to view the full text.
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.
