What's time. It's... 27 posts and 0 image replies omitted. Click to view.
What's time. It's not matter or energy, but it causes them to change. So what the fuck is it? And we don't really perceive time, do we? We only perceive our memories.
Okay, say there's a game... 15 posts and 0 image replies omitted. Click to view.
Okay, say there's a game played on a grid of white squares, 1000 x 1000 in size. Two players take turns filling in a single square. The first player who must fill in a square that shares a side with a previously filled in square loses. Assuming perfect play, is that game solvable?

is there any scientific theory that is close to discerning what may happen to our consciousness from a conscious frame of reference in death? is something like the Boltzmann brain applicable in this context?

Is this remotely accurate, or is it just one of those close enough to bullshit it coincidences?

Any medical /sci/entists? We have a male 16 year old suffering from an undisclosed (though claimed untreatable) neurological disorder. Which up until recently went diagnosed because he thought it was merely "his personality, unique". The medical files have been lost but it was reportedly a rare condition. Ideas?

Dear uncon/sci/ous, I am making a spinthariscope. I got the idea from http://unitednuclear.com/index.php?main_page=index&cPath=2_12 and found a video about harvesting throium dioxide, but http://bobgrove.org/html/radiation_detectors.html has led me to americium oxide, I have a old smoke detector I can replace and harvest from it. I've gotten 3 65"+ fresnel lens from free tvs, and they each had 3 lens that I posted, 1 set is very large, 1 set is smaller than posted, I plan on using 1 of these for the magnifying lens, but fear the focal length is too long, may have to harvest telescope eye piece. I plan on using phosphor from a old crt I will hopefully find free on craigslist. In a few days when I have all the supplies gathered I will post again with what I did, and what I learned for future builds, might make 2 with one using zinc sulfide vs phosphor. I will take a few pictures and might roll them into 1 screen cap with simple instructions to make a /diy/ nuclear toy. I will probably post instructions on /diy/ too. I come here to ask for advice radiation source, I figure the more Counts Per Minute emitted will give a better show, and compared to americium oxide, thorium puts out more - but I would have to harvest from lantern mantles, I may try this later when I have money to spend. I'm doing this on a budged, so is a $5 smoke detector the cheapest way to obtain radioactive ore? I will check craigslist for a free old one. I know thorium dioxide dust is bad inhaled.

Hey /sci/. Non /sci/ /b/ and /r9k/ queer here, i am not worthy. However, I'd like to ask, And hopefully start a discussion- What are the chances of planets that have or are capable of developing evolving ecosystems with plant-life, water, Animals, etc? Not the possibility, Because even a pleb like me knows you'd have to be retarded to not think its possible, But what are the chances, and how many may there be? thanks for your help xoxo <3

ITT I post OC of a stupid beaner on Facebook saying science is for the "intellectually limited"

/sci/, yesterday my friend showed me a video, it was a "graph" of some sorts that went from negative infinity to positive infinity, and every number was represented by a different shade of color, and as you zoomed in the graph became more complex until the end of the video where the same figure that was at the beginning appeared again. It had a name, ______'s (something). I know I'm probably not explaining this well but I want to read more about it and I'm having trouble finding it.

I just graduated with a math degree. What do now? My interests are money.

Is there any basis for drinking diluted apple cider vinegar as a health supplement? Saw a thread on /ck/ and they're debating about whether or not it's real. I guess this goes for any over the counter supplements.

Order of Operations

I am having a difficult time conceptualizing this, if that's the right word for it. I understand the method, but not the reasoning. Why this order? Why not perform every action listed from left to right?
