I have Concerta. Each pill is 54 mg. I know I'm not supposed to crush and consume it as it would release all the stimulant at once, but couldn't I divide the pill into like 6 parts and swallow 1 part? Pic unrelated.

Holy fucking hell I hate this piece of shit. Why do I have to use it for everything, why can't I just do my shit in an actual coding language, fuck you shitty engineering program fucking fuck your errors mean NOTHING AT ALL.

Let A and B be n x n matrices such that AB is invertible. Prove that A and B are invertible. Give an example to show that arbitrary matrices A and B need not be invertible if AB is invertible. can you help, sci?

What real numbers have multiple decimal representations and what real numbers have unique decimal representations? Do some real numbers have more than two decimal representations? Is it possible to describe the set of all real numbers that have multiple decimal representations? Pic unrelated. I didn't know what would be a suitable picture for this topic, so i just grabbed the first thing at hand.

An underdetermined system has an infinite number of solutions (more unknowns than equations). But what does it mean to calculate the least-squares solution for an undetermined system? Since there are infinite exact solutions, wouldn't the least squares solution be any one of them?

so. newcomb's problem. A powerful alien, who, far as you know, is always right about everything and never lies, tells you this: "I have two boxes. Box B has $1000 in it. Box A will have either $1000000, or nothing. You can either take box B, or take both boxes." "If I predicted that you will take just box B, then I would have put $1000000 in box A. If I predicted that you would take both boxes, then I would have put nothing in box A. Either way, the decision has already been made, and I will not change my mind now regardless of what choice you make." Do you take box B, or both boxes?

http://en.wikipedia.org/wiki/Occam%27s_razor >It is possible to describe the other planets in the Solar System as revolving around the Earth, but that explanation is unnecessarily complex compared to the contemporary consensus that all planets in the Solar System revolve around the Sun. ~ Wikipedia.org So, the church wasn't wrong when they were arguing that the other planets are revolving around our planet?

Soooo... do you believe this makes sense? I'm hoping for assistance on an equation and/or explanation: The Hubble Space Telescope can see stars and galaxies where brightness is 1/50 of the faintest objects now observable using ground-based telescopes. Use the fact that the brightness of a point source, such as a star, varies inversely as the square of its distance from an observer to show that the space telescope can see about seven times farther than a ground-based telescope.

Help? exam review problem, cant get the right answer What is the maximum possible coefficient of performance of a heat pump that brings energy from outdoors at -3.00°C into a 20.0°C house? Note that the work done to run the heat pump is also available to warm up the house. i got 11.73 but that isn't correct, anyone know what I'm doing wrong? 270/(293-270)=11.7391 seems to make sense, but its not right

Why is the navel sensitive? For that matter, why are in the inside of the wrist and the back of the knee? I know it's because they have lots of nerve endings there, but why? What purpose does it serve? With fingertips it's obvious, but not these.

How do you explain it from a scientific point of view? If not aliens what could it be? http://youtu.be/bTqE805dhOE

Hey, not asking for answers here, just how to answer if that is possible. "Using Excel, answer the following questions; 1. For loads between 200 N and 800 N, the graph of load (y) against extension (x) is approximately linear. Find the gradient and intercept of this portion of the graph."

Hello What is "a"? I know you can do it!

P(A)=0.6 What's the probability that you pick exactly 10 A's out of a set of 20? By my logic, that would be as follows: [mathP($Exactly 10 A's out of 20$)= \frac{\binom{20}{10} \cdot 0.6}{20!} Can somebody please point out where my error is? I've played around with this on my free time for days (I have hardly any free time at all nowadays, so it's not that long), to no avail. I'm gonna go insane soon if I can't fucking solve this. Please help a guy out. Believe it or not, this is not homework. I'm gonna have to go AFK again, I'll be back in 4-16 hours depending on my workload for the day.

Does /sci/ have any more infographics? I only have two as of now

Any video's on youtube that will blow my mind /sci/ ?

Ran across this and only a couple if hours voting left. There is only one science project in the top, so if you feel like helping out, vote for the 10k or share the link! befearless.casefoundation.org/projects/portland-junior-scientists/meghana-rao

the probability of getting x out of the items is 0.1, if chosing 10 what is the chance the none come out as x? One comes out as x? and two come out as x? Do I stack the probability and is 99.9% the anser for 0 coming out as x if the other is 0.1?
