>>8243294 The watch in that picture goes for something like $300,000. It couldn't POSSIBLY be because of how impressive it is from an engineering standpoint, right? Discounting the brand name, the precious metals, all of that. How impressive is the technology behind a mechanical watch like this?
>>8243336 I mean more of how impressive it all is. That's really what I'm asking. The watch in the OP, the back there, it looks very intricate. I'm wondering if that costs a lot and is part of the price or why people are so interested in them, or if it's 100% a brand thing.
I'm looking for a good, thorough, textbook on neuroscience. Something more focused on the low level. eg, voltage dependent calcium channels, pyramidal cells encoding their outputs, feedback loops and rate limiters for neurotransmitter synthesis, etc. Something a bit more functional than a more anatomically oriented perspective.
I'm aware of the stickied link, but would like some more firsthand opinions.
>>8244414 I'll look into this, thanks. From the sound of some of the reviews it might be close to what I'm looking for. Something that doesn't dick around and try to hold your hand, creating an unnecessary metaphorical and abstraction overhead.
It's a machine. Material that clearly lays out what we think it is, what we think it does, and how, seems rare. Greater meaning is then rendered implicit.
cancers are small people just like you and me,so to detect them in your brain,the doctors must give you a cancer amplifier so the tomography can be done right.But if you dont already have it,you might just get one,go and scan yourself tomorow,who knows what you might find
Alright /sci/ I want to prove to you that psychic interaction is possible "once and for all." There are two problems with this.
1. If I can't do it reliably, it can't be called science. 2. Proving that it's one thing and not just clever manipulation or some other type of engineered "coincidence" requires a strong mind and proper wielding of Occam's razor.

A few weeks ago I was thinking about the idea when I decided to calculate how much money would be needed to make such huge endeavor work.
For the purpose of that conjecture, here is the full scenario:
>Ship will carry 25000 people in cryogenic sleep (Heart beats 3 times a minute, lungs breath in once) >ship will also carry seed banks, soil samples and embryos of dozens of animals for future use (Chickens, cows, pigs, etc) >Speed will be about 0.2c to 0.25c >the...

>>8246927 Then there is the fact that no rocket is cheap enough to build the colony ship in orbit. It just doesn't work economically speaking. Even the biggest and cheapest of rockets would still make the project way to costly for any non-emergency scenario (i.e. extinction event and people stop caring about money cause they wanna save themselves). To circumvent this I added a space elevator to be built on the equator. It would allow for cargo to be transported up 24/7. Maybe completing the trip to geosynchronous orbit... Comment too long.

>>8246940 Im gonna be honest, I don't remember. The numbers got so big and mixed in the end I just remembered the 2 trilion mark. However, as I said, I got to it by:
>calculated how much energy the elevator consume in dollars to carry the cargo up, and multiplied that number by 6 to account for the cost of the cargo inside it and workforce building the ship in orbit
So maybe I can re-do it sometime. I also think I assumed the elevator had it's own nice nuclear reactor on... Comment too long. Click here to view the full text.
>There are many “leaks” in the so-called STEM pipeline, including educational shortfalls and cultural issues like stereotyping. But there may be one issue in particular that’s having a profound impact on the number of women in STEM: the notoriously difficult college math class, Calculus I, a new study from Colorado State University finds.
Hopefully going there next year, should my results be good enough (God wills)
What should I keep in mind before I go there? Anything special about the science departments?
I'm signed up for physics, but I might switch to engineering. I don't want to do research, and I want to open a technology or engineering company, so I feel learning how it all works will be more useful than heavily theoretical physics.
Is there enough gases trapped in the ice caps that carpet bombing them would release enough CO2 to create a sufficiently pressurized atmosphere? Is there enough oxygen and water in the ground to provide for biochemical processes?
What kind of time frames and challenges would we be up against?
>>8229624 I'm willing to wager that there isn't enough trapped in the ice. Having little atmosphere isn't as big of a deal as the Microgravity problem, as well as the lack of a magnetosphere which would mean constant bombardment of harmful solar radiation during the day. The magnetosphere also would help keep the atmosphere on the planet, as the sun is stripping the atmosphere away, albeit very slowly.
>>8229624 >How would we go about terraforming Mars? Slam another planet or decently sized moon into it then wait thousands of years for it to settle down. By then we likely would have better technology which could terraform other planets in other solar systems.

I don't wanna sound like a crazy creationnist that I hate but some stuffs are simply impossible: - the gap between the first random mutation that is not usefull and the lot of mutation needed to produce something usefull that pass through genes is simply too high in some molecule/structure/cells etc. Like the probabily is so small that even 4...

I'm asking seriously here, not with that smug sense of superiority so many STEMtards have when it comes to this kind of thing. What is it about math (and to a lesser extent science) that leads to such a volatile hatred of the subject?
Math has a defined wrong or right answer when we start out, which always motivated me to improve. I got more questions wrong than I did right, but I didn't care because I was learning. However, I propose that most people see failure not as something to learn from and recognise as a usual... Comment too long. Click here to view the full text.
>>8243083 All abstract subjects seem inherently unnecessary to all but the practitioners of that discipline. For the same reason that a modern mathematician might scorn archaic disciplines, while the practioners of those discplines viewed their own abstractions as usefull and simple.

Ode to mathematics, seriously, this http://www.writeurl.com/text/6un773amggkc3zr2ejpy/wbdvympgflbebyiihalc text's point you completely missed, applies sciences and all sciences to their absolute points, if it's necessary! Needed.
Great mathematicians know how be happy, and get shit done without stressing out, or being bossed around, something only few know how to do.

This text is part of a solution I used to get the full time job I wanted. Mostly it was just a matter of how a person should behave among other people. So it turned mostly into calculating a simulation of a fictional personality in different scenarios, that eventually I'd run through using my own body. And, those calculations were correct, since I managed to reach the goal.
What I mean attack, valuable input, could you make those calculations even better, more accurate?

Why are imaginary numbers taught in high school and basic astronomical navigation not? Imaginary numbers would only be more helpful than something like astronomical navigation if the individual were to pursue a career in mathematics or physics, outside of that its virtually useless.
>>8244366 Our languages (at least, western languages?) have this assumption of free will in the way they build subjects in sentences. Well.. if you say someone (3rd person) made a lot of effort, that just means he made effort for whatever reason, as a response to whatever impulse his environment sent his body.

And man, I don't want to sue my mom - she was an ignorant signee who was coerced into it. She's not a medical professional, she shouldn't be expected to make that decision. That's like telling parents to decide at birth whether their child should have nipples. And being fed a bunch of bullshit about why nipplecision is preferable and that many people do it.

I'm interested in biology. I have been interesting in life ever since I was a small child. I would spend days turning over rocks and studying the bugs underneath. I went through a dinosaur phase which made me interested in evolution, which led to an interest in genetics, my current field of study.
My parents also had a role. They would encourage me to practice math since I was small, and they discouraged me from going into the humanities, which was another interest of mine. I still study history as a hobby but I am glad I went STEM because the way I see it, it is... Comment too long. Click here to view the full text.

>>8240963 problem: 666 green kids decided to post in this thread between 5 pm inclusive and 6 pm exclusive. All green kids will post at least once. Time of the first post for all green kids is equally distributed between 5 pm inclusive and 6 pm exclusive. When a kid post in a thread, he stays for 15 min to write one replay for everyone who had posted in this thread since his first post. At 6 pm all green kids left the thread. What is probability of all 666 green kids getting 665 replies by green kids?
