  1. Obiviously, triethyl orthoformate is more acidic than ethnol. Because Triethyl orthoformate is an orthoester of formic acid and ethanol. So generally it's more acidic than ethanol. But I don't have some sort of reference. I can't it by googling,too.

    But when both of them deprononated, the negative charge is on oxygen of triethyl orthoformate, while on carbon of ethnol.

    1.According to rules learned from organic chemistry, the negative charge on a more electronegative atom(eg. O) is more stable than on less electronegative atom(eg. C).

    2.According to rules that when the conjugate base is more stable, then the conjugate acid is more acidic.

    So,we can conclude that triethyl orthoformate is less acidic than ethnol.

     

    Seemingly contradictory? I don't know where am I wrong.

    What is it you are trying to do? how will you hope it works?

  2. Oh, the rock will be obliterated and the material from the ship will keep right on sailing away at high speed, but the ship won't be intact. The rock will "burn up" the ship just as much as the ship "burns up" the rock.

    Look, it is already working, as they are on mars at the moment, yes?

     

    If you were to emit photons in front of the ship, it would destroy the 'rocks,' burning right through planets and asteroids too, yes?

     

    Now, if you were on my forum, I could tell you how to emit photon's from a laser, powered by a particle beam accelerator engine or plasma or proton engine, as I have theorised them all. They refuse to build the quasar engine as it is too dangerous, but the fusion engine is working on those space ships outside mars. Basically, what I can remember is that you take the two positive ions and place negative ions around them to force them together enough.

     

    So, with this engine emitting a powerful laser in front of it, it can destroy all things that get in the way. of course, if you want to go that fast, you need to use nitrogen four, as it is not carbon based, and is a building material. hell I even theorised how to belt that stuff out on a conveyor belt, along with all other metals, using atomic heating and restructuring. Basically, you use four lasers that intersect in the middle on top of a conveyor belt, and make it so that they meet in one point, using all sorts of things I have forgotten about, as I did this in 2009, and then you belch out materials. If the atoms were heated, and stripped or added to, with artificial atomic structuring, it is possible.

  3. Hello world. [The obiliatory] Sorry if this is in the wrong section, this is my first post on here. Forgive my wall of text/mini rant.

     

    I have some anxieties about graduate school and was hoping for a bit of guidance; I am nearing the end of the second semester of my junior year so I will be applying to grad schools before long and wanted to hear your thoughts on some things. I am working toward my B.S. in psychology with a biology minor and I have realized that the area I really want to go into is neuroscience, in particular I think I am leaning toward the molecular/cellular side of neuroscience/neurobiology. I chose a psych major because the brain has always been of interest to me but I've come to realize that psychology is not where my heart is, it's down in the proteins and the DNA. My major interest is really in neurodengerative disease, everything about the entire spectrum of neurodegenerative disorders is simultaneously utterly fascinating and the most tragic thing I am capable of imagining, both reasons why I want to pursue the topic. I have questions about these disorders for which answers do not yet exist and I think if I'm going to find my answers anywhere then it's on a molecular scale.

     

    In looking at graduate schools, almost all seem to say something along the lines that competitive undergrads have taken courses in calculus/organic chem/physics/advanced bio. The thing that makes me anxious is that by the time I graduate I will not have taken organic chem, physics, or calc. I've got bio under my belt, and by the time I graduate I'll have done general chem. However, I haven't taken calc or physics because I am terrified to death by math, and by extension physics (high school physics was one of the worst expereinces of my academic life, though it likely was just because of my teacher I've been put off from physics ever since). Additionally, there was a hiccup in me getting general chem done (the first time I tried to take it, the classes filled up before I could register and the second time I learned that my math prereq for psych did not qualify me for chem, so I had to waste a semester taking a 100 level math class). Frankly, that single greatest regret I have about my undergrad career is that I'm not going to get to take organic (or biochem).

     

    That said, I'll will have taken two semesters of general chem, genetics, two semesters of anatomy/physiology, molecular bio, a molecular bio lab, cell bio, the lower level bio (two semesters of intro bio, biodiversity), sensation & perception, psychopharmacology, physiological psych, behavioral stats, and any other science that I can cram in in the next two semesters. I have a 3.6 GPA, I haven't taken the GRE yet but I'm studying for them, I have begun working in my schools lab for comparative neuropsychology so I'll have about a year under my belt when I graduate. I'll have three reccomendation leters from faculty who actually know me- one from the lab, two from biopsych professors who I have TA'ed for (one is chair of the department, the other recieved her Ph.D. in molecular neuro if that adds anything). Finally, I have been trying to learn organic on my own, I can't say that I took the class but at least I can say that I put in the effort to acquire the knowledge, right?

     

    What I'm trying to get at is, does my lack of organic and physics totally kill my shot? I know it puts me at a disadvantage and I don't claim I'm ivy league, but I do know a thing or two about a neuron or two. If I were interested in something like cognitive neuro then I would not be as worried because alot of schools say that that requirements for acceptance are flexible, but in going for molecular- I just don't know. I just need someone to put a pipette in my hand and give me the opportunity to show that I am capable of doing something astounding. Can I just get some thoughts, please?

    Okay, so you want to study neuro degenerative diseases. the best way to do that is to ditch the psychology, as that is cultural, and then ditch the physics, as that is about nature.

     

    Once you have done that, you should look up a bit of something that covers conductors in the brain, as the whole thing with a disease of the nervous system, comes from reduced current in the brain and nervous system.

     

    I have always said that the brain does not store memories, as they are in effect rebounding in the nervous system, through sensations. the memories you have always rebound in the nervous system, as they are carries over nerves.

     

    If you want to cure diseases of the nervous system, or something like that, I suggest you look into producing your own degree! If you were the first to postulate the degree with the diseases, you could become like uber famous!

     

    So, read up on conductivity, biology and in biology specialise on white blood cells and red blood cells, as they fight diseases, and then maybe a bit of your own tests, if you can find funding. Of course, you could go somewhere great with this, but the way typical people in the field go is with a separate course anyways. if you could take this course and turn it into a degree, sky is the limit.

  4. Unless it's an ark ship, it needs to be going at an appreciable fraction of the speed of light in order to reach another star before the crew is too old to do anything much. At that speed, I'm not sure how much good kevlar is going to do when a space rock hits you with the equivalent force of a small nuclear bomb.

    It is going too fast. it will 'burn' the rocks up.
