Length contraction

Have a question on length contraction. >According to a certain road map, the distance between Baltimore and Philadelphia is 160 km. However, if you travel from Baltimore to Philadelphia at a significant fraction of the speed of light, the distance between the two cities will be much shorter than it is if you travel at 100 km/h So if this is true then does that mean the distance of a light year is not absolute? The speed of light is 299,792,458 m/s. Light that travels for one Julian year (31,557,600 seconds) will cover a distance of 9.460730473e15. I'm going to call this distance D. Now onto my issue, if light travels this distance D at the speed of light, wouldn't length contraction cause light to travel a distance less than D? Any thoughts?

Statistics

0 posts and 0 image replies omitted. Click to view.
Does /sci/ know statistics? I feel like a fucking retard because I have been working on this project and can't decide what parametric test is the correct one to use for the final hypothesis I'm given. Can anyone help? What test would you use for this question? For patients receiving the placebo, was there a significant decrease in seizures, on average, from the 8-week baseline period to the 8-week follow-up period? As a little background, basically some people were given a placebo, and others were given a pill. They were testing to see the pills effects on seizure frequency. None of that really has any effect on the question, but I figured that might help clear up any confusion on what the question is asking. My best guess is a one sample t-test but i really dont think that is correct

Science Teacher

Coming to 4chan with this might turn out to be a mistake but I am willing to try about anything to make my dreams of becoming a science teacher come true. http://www.gofundme.com/gsxh4c if you could please share this link or donate anything at all I would be really appreciative

Is diamond a metal?

2 posts and 0 image replies omitted. Click to view.
Since diamond is an allotrope of carbon (Other is granite) and carbon is classified as a nonmetal on the periodic table, does this mean diamond is a nonmetal substance?

So they found organic molecules on an asteroid, the Philae probe found some before it died. Does This confirm that comets/asteroids are just delivery methods of life from some grand source? Or am I just late to the party.

Non-Dominant Hand

8 posts and 0 image replies omitted. Click to view.
/sci/, I'd like to be able to use both my hands in any situation, i.e. become ambidextrous. Problem is, I've read that as you increase the mastery of your non-dominant hand, your other hand becomes harder to use. Is there any truth to this?

/sci/ I have a question for any of you into medical technology and the likes. How long does it typically take for an innovative improvement technology to be implemented in hospitals? So not a totally novel technology or anything, but one that improves on another that is already implemented. I have read so many articles and I can't find shit beyond the JSM article "The answer is 17 years, what is the question: understanding time lags in translational research" but that I believe is specifying from when research begins and when it comes out, not necessarily when the research is implemented in a health care setting.

What is your favourite number and why? I'll start, mines 9! because in maths lessons I always used to play with factorials and nine factorial just always felt so right.

I'm so confused and despite trying to google an answer by asking the question in various different ways I can't find an answer. I am an idiot and I need to know.... uh.... How systems relate to other systems? Okay so I know the milky way galaxy is this big spiral right? And I know our solar system lies within... But what would the nearest solar system to ours be and where is it in relation to ours? If you left our solar system would you just fly through empty space for a while and then reach a new solar system? How close is that system to ours? What keeps those 2 systems apart? What do we call the space between these systems? I know this is basic stuff but I'm an idiot who suddenly became curious....

It certainly requires more and more ludicrous things to classify as “oppressive” in order to stoke its never-ending series of self-legitimating moral panics.

The fact that this occurs so frequently and so uncritically is startling.

/sci/, I have a confession to make, I.. I have a problem with corners... where to they end, how do they start is there sucha thing as a simple edge? I need help and this is the only place I can think of to muster the genius needed to solve these problems >I will trade you this information for help

Can gravity be converted into usable energy? Gravity obviously keeps entire planets in orbit so is there anyway to harness that power?

How is 800 / 8 = 100? I get that there are 100 8s in 800, but how come you divide 8 by 8 and then put the 00s to the right? You're dividing 800 by 8, not 8 by 8.

Any geologists here? Undergad here. Im combining my two final projects in glacial geology and remote sensing. I need to choose three glaciers in the same general area with similar properties, but different lengths and high fluctuation of ice thickness throughout the last ~50 years. Id like to document the correlation between size, ice thickness, and response rate. Due to high availability of remote sensing datasets in North America, id like to stick with Alaskan glaciers. I need to minimize all the variables that influence response rates in order to collect more accurate data as well, so this should take care of climate differences. Columbia and Mendenhall both have extreme ice thickness loss which is best for documenting using ASTER, but theyre relatively different from one another. Im looking for possibly 2-4 glaciers that fit this description. They dont all have to be the same type of glacier, but i think keeping them all valley glaciers would make things easier as well. Any ideas? inb4 >geology >2012 >real science

Oligomers

3 posts and 0 image replies omitted. Click to view.
Hi /sci/ Does oligomers have the same functions/actions as their monomers? I was wondering if Triton X-100 and Triton WR-1339 have the same mechanism of action in inducing hyperlipidemia. Triton WR-1339 is an oligomer of Triton X-100 (heptomer, specifically) Triton X-100 is 4-(1,1,3,3-Tetramethylbutyl)phenyl-polyethylene glycol while Triton WR-1339 is 4-(1,1,3,3-Tetramethylbutyl)phenol polymer with formaldehyde and oxirane. I was trying to look for the mechanism of action for the induction of hyperlipidemia using X-100 but I was not able to find one. WR-1339 on the other hand is typically used to induce hyperlipidemia. Although X-100 has been used in inducing hyperlipidemia in studies, I can't seem to find its mechanism of action. Please help
