Is space discrete? General relativity and quantum theory say no, but both LQG and string theory say yes
If it isn't discrete, then you have singularities and everything is fucked
If it is, then space is a grid and special relativity is fucked because effect can precede cause
Please help me /sci/, this is driving me mad.

Well let me tell ya /sci/, I needed help. This machine didn't look much at all like what I had read about. At first, I wasn't even sure if it had ANY similar functions. After a couple minutes of close inspection, I determined that it was a little similar to what I had read about; close enough that I was fairly certain I could calibrate it and make a good first work impression on my professor (he knew my past work and academic history, but I wanted to show him I would be a valuable asset).

I switched the thing on, and was greeted by a constant humming noise after a few seconds. So far so good. I first tuned the voltage to the correct setting, and everything still seemed peachy. Unfortunately, I failed to realize a small light on the back that was flashing to indicate an inconsistency with some of the frequency settings.

Had I read the CORRECT manual, I would have noticed the light (who puts an important light in the back, anyways?), and I would NOT have tried to tune the resistance next. Well I did, and I began to hear a quiet whining noise that started to grow louder. If anything, I could say that this sound was rare, but I thought, "Nahh, forget it. Yo Homes, to Bel-Air!" I pulled up to the house at bout seven or eight, I yelled to the cabbie 'Yo home, smell ya later!' I looked at my kingdom, I was finally there! To sit on my throne as the prince of Bel-Air!

i searched around a bit, and i seen. you fellas don't have a thread about the string theory..So, What are your guys thoughts about it?

3rd bump for science

Well /sci/, do I have a story for you.

I am a nuclear engineer at the University of Illinois, and today was my first day doing research in the nuclear engineering lab. I assist a doctoral student with... things (I don't want to say because anyone who knows me would immediately know who I am). I can assure you though, it is nuclear engineering stuff.

Anyway, last night, I had to read an article on this special piece of equipment I would be calibrating. I had to find the article and stuff myself, so I googled it. For whatever reason, I could not find the EXACT piece of equipment, but I found one that I assumed was the same thing (it had a dash and then some numbers after the product name, I figured it should be basically the same).

I read this whole instruction manual on how to calibrate it and stuff, and it ends up being like twenty pages long. I read it slowly and carefully to make sure I remember everything and will be able to do my job tomorrow.

So this morning, I head to the lab to meet my professor, who asks me if I read what I was supposed to and will know what to do, to which I respond yes. Despite the twenty pages of reading, the procedure was actually pretty simple (or so it seemed).

I was led into the adjacent room, which was dimly lit. The walls were all concrete (cheap material with good halving thickness in case things go wrong) and the building itself just felt musty. He sat me down in front of a machine saying, "I'll be in the next room if you need any help."

Well let me tell ya /sci/, I needed help. This machine didn't look much at all like what I had read about. At first, I wasn't even sure if it had ANY similar functions. After a couple minutes of close inspection, I determined that it was a little similar to what I had read about; close enough that I was fairly certain I could calibrate it and make a good first work impression on my professor (he knew my past work and academic history, but I wanted to show him I would be a valuable asset).

I need some help with mathematica. Didn't really know where else to post this. What do I type in if I want to graph tan (x^y) = tan (y^x)?

I'm 19 and I've been depressed since I'm 7, how long before I go potato? Knowing that my depression is the reason for making me stupid makes me ever more sadder and depressed. How fucked am I?

Will they ever prove it's right? Can they?

/sci/ please help. I spend an hour per day commuting and basically listen to rock or pop music the entire time.

Is there anything out there worth burning to a CD that would be interesting and educational but also easy listening?

Your suggestions are much appreciated.

>pic unrelated but part of the 4chan library

you'd understand it more through mathematics rather than words.

Hey /sci/

I don't usually post but I've got a question.

A friend and I are discussing the universe, he seems to think that due to the timescale humans are the most advanced species in the universe due to it taking 3.6bn years for life to evolve and it taking the first stars 10bn to produce carbon. I've never heard of it taking taking that long for carbon to exist in our universe.
From my understanding the first stars lived and died within 300 million years, and would have expelled carbon when they went supernova.

So who, if either of us, is closer to correct than the other?

Interest has I always been in String Theory.

However, math is are very complex and make very hard understand I can.

How you do math with theories like this?

Hey /sci/, Imma be participating in a science fair this coming spring for the first time, a county science fair, and I was just wondering what kind of work it entails. If you would be so kind, please give your experiences, and recommendations if any.

Hey, I have a D&D 3.5 question: How much control does the Genesis spell give you?
In the book it simply says that you can control temperature, lay of the land, water features, and other such facets, but can it do more and how much more? Can you actually alter the laws of physics and reality upon its creation, allowing for a world where even the slightest footfalls cause nuclear fusion? Can you create a realm where quantum mechanical effects are manifested in grand scale, allowing all possible realities to exist and play upon one another? Can you make one where the dimensions are incongruous with our own, like two time axises and five spatial axises? What about a world where the passage of time is out of synch with the regular worlds, so five years inside is equal to a femtanosecond outside? What about one where time flows backwards?

Not my question, but sounded interesting, what do you guys think, more on the consequences and difficulties in such, less than the rules lawyer part?

gonna bump with random pics for a while.

/sci/ if you could explain String theory in one sentence, what would it be?
