A blog inspired by the analysis of how one would collapse Jupiter into a black hole, but primarily consisting of other of my own esoteric musings.

Nano again
So November is NAtional NOvel WRIting MOnth or nanowrimo for short. The challenge is to write 50,000 words of fiction during the days of november. I have yet to fulfill this goal even once though I have been participating to various degrees in nano for 3 years (this will be my 4th year) This year I'm really going to do it though! Of course I have slightly less than no idea what I am going do to for the novel this year. I am really open, at the moment it could be anything from a book about a group of jumpers orbiting a post implosion Jupiter, which is now a singularity used for warp research to a book about how the only thing known to kill vampires are cigarettes.

Death to Tyrants
For the few rare souls who actually have visited this blog more than once. Why on earth did you come back? The content of this blog is perhaps what you might aptly call eclectic, yet another apt title might be completely disordered badly written ruminations of a crazed and unstable mind. Because of this I would be willing to bet that the thing that gives cogency to the group that is my readers is none other than personal acquaintance which lends interest to the blog even though. The content is terrible. Is this the case? Please tell me in the comments.
P.S. The title of this post is intended to imply that I am acting as a sort of content tyrant. I cannot stop being the content dictator but if the content is bad then that makes me the content tyrant since my rule is unjust. So give me some feedback and hopefully I can become the benevolent dictator instead of the unjust tyrant.

Do You Know Me Personally?
The poll with that as the question has finally come to a close after a year of polling.
The poll got a total of 22 votes which I hope is less than the number of people that actually visited the blog in a year. Still 22 people isn't bad and I am particularly pleased that only 7 (thats 7/22 or approximately 100/pi % thats 31% ish) of them claimed to know me while the majority 15 (68% ish) of them claimed to not know me at all. This is heartening, since it means my blog is not entirely invisible on the web. Furthermore it means that the blog has more pull than merely the pull afforded by personal acquaintance with this nut.

Fractional Dimensional Spaces and Fourier's Trick
One doesn't usually think of the existence of the standard basis for euclidean vector spaces as related to fourier series. It is easy to show that there is a rather direct correspondence. If we take a slightly non standard method of providing a coordinate system to the points in Rn we let every point p be labeled with a the function defined using the usual dot product as fp(x) = p * x where * is the vector dot product and x is any other point in Rn Now to obtain the dot product of two points we express each point as a linear combination of the standard basis vectors and then take the sum of the products of the corresponding coefficients in the standard basis expansion. More to the point if you take the dot product of one of the basis vectors and any point you obtain the coordinate of that point with respect to that basis vector. Thus the dot product of two points is the sum over the standard basis of the products of the dot products of the two points under consideration and the i'th vector in the standard basis.
Now consider what happens when we take our above functions mapped to points. We can obtain the dot product of the two points as the integral of the product of the functions associated to the points over the unit sphere of vectors. If the space under consideration is integer dimensional space then relatively simple exercises in linear algebra show that any point can be expressed as the linear combination of d linearly independent vectors (d being the dimension of the space). So (as is kind of obvious) if a (finite) standard basis exists then the dimension of the space is integer.
This is all based on the fact that the space has a vector space structure set up on it. I posit that vector space structure does not in itself imply the dimension of the space to be of integer dimension. If this is true then it means that any non-integer dimensional space would have to have an infinite basis

Problem Solving
At least once in a while I should post something with some personal interest. It is strange how reading something which is happening in someones life that you don't even know can be entertaining. I suppose what is on my mind at the moment is problem solving.
There is an undergraduate problem solving contest here at the U where a new problem is posed once a month during the school year. People submit solutions at the end of the month and are assigned points based on their solutions to the problems 3 points for a correct one and +e points if you win. I have found that I can solve a significant fraction of the problems but that also sometimes I spend dozens of hours working on a problem only to be unable to solve it. This last problem really made me angry when I found out how it admits a really simple solution and even one that I sort of thought about before. you have a 7x7 checkerboard with a black square in the corner. What single tiles can you remove in order to make the board tileable by 2x1 dominoes? The answer is you can remove any black square and not any red squares. I worked on the problem for hours and made it more and more complicated... but I couldn't figure out how to prove that removing a red tile made the board untileable. The amazingly simple thing to realize is that there is one more black square to begin with on the board and every dominoe covers a red and black square thus removing a red square leaves the board untilable since it leaves the number of black and red squares unequal. An even more elegant solution deals with finding even paths on the board which gives you both the black and the red tile cases in one go. The really infuriating thing is that I considered both the fact that every dominoe covers a red and a black tile and the fact that the existence of eulerian paths on the dual graph of the board is related to the tiling.... and yet I didn't solve the damn thing. I guess I am really just not capable of doing personal happenings rants. I just get caught up in the details of whatever little abstract thing I mention. I'll do better next time.

The Fiend of Finance
As it so happens I find myself in a relatively uncomfortable financial situation. I have made it almost the entire length of my undergraduate career without resorting to a job. I have worked of sorts since I have done some research for small grants but I have not entered into an employee employer relationship while in school. I did however have a job before I started and retained that job for some time while I was in school during the first year. I now find that I must come up with some new way of acquiring monies. The prospect of getting some sort of gainful employment however is not something I relish. I suppose I should give myself some sort of period during which I can pursue different paths which are less likely to allow me to have stable financial self support but which are all together cooler than the usual resort of a 9 to 5.
List of ways to get monies
1. Sell things on e-bay: obviously in order for this to work for an extended period so that it can provide some sort of illusion of financial stability I would have to find a way to supply the items which are to be thereby sold... thus making this option not terribly useful without a supporting money making concept, see following items.
2. Sell handmade wooden puzzles: actually I rather like this option as it does not require a great deal of technical prowess, I already have (or more precisely already have access to) a great number of woodworking tools, last but not least I can put as much (or as little) originality and ingenuity into the creation of said puzzles as I like.
3. Create and maintain an original software package: This idea is so varied as to require an entire sublist of the possible sorts of software enterprise that could be undertaken. I could try my hand at engineering a game, a map maker, a fake language generator... etc.
4. Make grandfather clocks: Unlike the wooden puzzles thought these objects would sell for quite significant sums of money and would still be a great deal of fun to make. Apparently I can purchase the actual clockwork parts of these devices online for rather less than I could sell the finished product... however of course the thing that makes the toys attractive is that they can be made and sold easily and shipped as easily. Selling these things would be I imagine rather more difficult. $500 clock anyone? (and that is dirt cheap for a grandfather clock...)
5. Sell my body: Specifically I mean "donate" blood plasma which is relatively easy to do... but it would weaken my immune system probably leave me with scars after a while and is not that pleasant in general. On the bright side it would force me to eat regularly (which is something that I do not currently do). However the monetary gain has severely limited potential since I can only give so much blood plasma a month (shame on them for stopping you before you hurt yourself). I have already done this a little and I must say in most ways I prefer being scared of going hungry to selling blood plasma.
6. Shamelessly beg for money on the internets: this is related to #3 since I would probably have to put my software out for free and then ask for donations, alternatively of course I could put a portion of the software out for free and then have other portions which would have to be purchased but there is something deeply satisfying about knowing that all of the money you get is given not because it was required but because in some way the person giving it felt it was deserved.

Black hole NMR and non-integer dimensions
Lately I have been thinking a great deal about the nature of real dimensional spaces. That is spaces whose dimension can be any real number not just an integral value. A method by a Yurosevich Koloskov is to use a kind of stochastic metrization of the space which is something I don't entirely understand but I think is a very interesting thing to try and look into. I think however that very probably in order to be able to build up the geometry of a probability space that would give rise to the kind of appropriate structure to describe Scroedinger wave type behavior we will need to be able to handle geometries of spaces with non-integer numbers of dimensions. This is backed up in some small degree by the practice of dimensional regularization which is a renormalization technique which assumes a non-integer number of dimensions in order to obtain renormalizations that otherwise could not be achieved. If the geometry that could be used to describe the quantum world is ultimately (even in the limit of the multiverse) necessarily stochastic (a kind of quantum gravitational bell's theorem?) then integer dimensional spaces should suffice to describe its dynamics I am not certain that the stochastic coordinate system mentioned above would be sufficient to encode these stochastic spaces as well but then part of the beauty of the idea of having parallel realities is that they make the geometry static instead of stochastic. The stochastic perception then comes from the constraint of path selection in a probability space which very likely is governed by a kind of action minimization multiplicity peak where the multiplicity of paths with close to minimum action occupying a kind of thermodynamical peak in much the way of the configuration of greatest entropy. At this point I think we finally have enough of a framework to begin to try and make headway on the predictions of this sort of world view.
I recently learned that the gyromagnetic ratio of a nucleus is dependent on the nature of the self interactions of the nucleus with the surrounding vacuum fluctuations. Since a singularity would constitute a kind of point charge with spin then it stands to reason that the gyromagnetic ratio of a singularity would be dependent on its charge its mass and its g-factor which perhaps could be calculated. using QED in much the same way that the calculations are done for the nuclei and point charges like the electron. If there were a reliable way to make a measurement of the charge and the rotation of some black hole as well as the magnetic field strength at a known distance from the singularity then we could test if the gyromagnetic ratio matches the predicted value. That could be a good place to try and get quantum gravitational observational measurements. black hole NMR
Also the g-factor of the singularity which we would be measuring might very possibly be dependent on the number of dimensions in which we are carrying out the measurements. which could be a good way of trying to figure out something about the geometry of spacetime on quantum gravitational territory.

Neural Modeling & immortality
The human brain has about 1011 neurons and for each neuron there is an average of a few thousand connections. If we forget about the details of both the connections and the neurons function etc. To have enough labels to uniquely determine each neuron we would need at least 5 bytes or so and conveniently enough we are moving into an era in which we are doing 64 bit computing. That is we will soon be operating on platforms that are big and bad enough to handle huge structures such as things with 1011 parts. Each neuron since it would have thousands of connections it is reasonable to say we could encode a neuron and all its connections with about 6.4*105 bits (around the amount of space the memory addresses of its connected neurons would take plus a little). Thus just storing the connections without weight or any of the ancilliary information such as connection strength time of signal propagation etc it would take about 6.4*1016 bits to store the connection information. That is about 105 TB of data. Now massive information storage of that magnitude is not something that you come across in your every day desktop computer, however on the basis of Moores law we could expect desktops to have that (conservatively) within about 32 years. Right now we can (and do) support massive data structures of that size in servers. The amount of computing power necessary to do effective computations using structures of such massive size probably will develop in parallel. The amount of data necessary to store the connections gives you order of magnitude expectations of what is required to store meaningful data on the structure of the brain. If we add extra data into the mix so that we store connection strength information about neuron type and sensitivity and stuff like that you are changing the required data only by some small multiplicitive factor. Although connection structure is definitely not the only important thing about the human brain even if there are hundreds or even thousands of similarly important characteristics you change the size of the required data by two or three orders of magnitude which means you need to wait 12 or 18 years for computers to get better or you need to be willing to make a super computer now that is capable of handling that sort of stuff. At any rate it would definitely appear that within the next 50 years or so computers will be powerful enough to encode and run processes similar to the human brain. Somehow I doubt that by that time we will have scanning technology or knowledge of the human brain sufficient to be able to scan a brain and put that information into a computer. The point is however that some time between 2040 and 2070 I am betting that personal computers will be powerful enough to in principle represent and support a structure equivalent in essence to the functioning of a human brain.
There are possibly some very large holes in this line of reasoning, for instance if the specific spatial layout of the neurons was very important to functioning or if previously unknown structures in the brain actually constitute a large part of its computational power or if chemical diffusion and the specifics of chemical processes in the brain are very important etc. I can't really know how much of the processing power of the brain is tied up in such things as the properties of diffusive chemical kinetics or neural knotting. If it turns out that it takes many orders of magnitude more processing power and space to adequately describe these processes instead of (as I was assuming) a similar amount of of processing power and information to encode and process the connection structure then it could take very considerably longer to really be able to represent the mind. At the same time though this is really kind of the brute force approach, try to make a computer be able to as precisely as possible model exactly what is happening in a human brain. While this approach has some nice allure to it since it is clear to see how its success is on some level relatively certain (assuming, as many people do not, that the physical functioning of the brain is what gives rise to the mind).
The possibility stands however that the particular form of neural computing that the human body employs is really very inefficient when it comes to producing intelligence. Perhaps we will stumble upon a better way of doing things somewhere along the way but I find that unlikely. Very probably we will not understand how we can do intelligence with finesse until we are capable of doing it with sheer brute force.

Collapsing jupiter with sound waves
because the mass of Jupiter is not sufficient to cause collapse into a black hole by itself the only way that we could possibly make this event occur is by means of a sort of burst compression activity. The condition upon which we will have made a successful collapse is that we keep a mass inside some spherical volume with the constraints that we keep the mass there long enough for light to traverse a diameter of the volume (so that the gravitational field definitely has enough time to set up) and also that the amount of mass inside the volume exceeds some threshold. The Schwartzchild radius is r = 2*G*m/c2 if you translate that into a necessary density based on the available mass you get m/V = 3 * c6 / (32 * Pi * G3 * m 2 ) You will notice that the necessary density goes down with increasing mass. Unfortunately c6 * G-3 is a really freaking big number about 1081 fortunately mass is in there as an inverse square so when you get to really high masses the required density is actually pretty low. If you happen to have a mass of about 1038 Kg involved then the required density is about the density of water.
If you read previous posts on my plan to collapse Jupiter into a black hole then you will know that I was thinking of a strategy that used several million megatons of nuclear bombs to drive a shockwave into the core of Jupiter in the hopes that I could drive the density of the region high enough to cause complete gravitational collapse. Recently I made a visit to INL (Idaho National Labs) and talked to someone there about the possibility of bubble fusion. The concept of bubble fusion is that you release bubbles of deuterium and tritium into some medium and have freaking loud sound waves resonating in the liquid. When the sound waves hit the bubbles of gas they violently compress it causing huge temperatures and pressures which theoretically can be enough to cause fusion inside the bubbles. I don't know if you could really get a positive energy yield out of doing fusion reactions this way. The guy I talked to seemed to think that a positive energy yield was completely out of the question. I genuinely think you could probably get a positive energy yield from a bubble fusion sort of device maybe nucleate the bubbles in a blanket of molten lithium you could get good shielding and breed tritium that way.
Bubble fusion is not the point though, the point is that resonance is cool and that maybe a single burst is not the most efficient way of going about doing it. Although producing many millions of megaton nuclear bombs is something that is theoretically within the technical grasp of humanity I would say that is still somewhat of a brute force strategy. What would otherwise have had to be done all at once in a huge burst of energy could instead be done over a period of years of carefully tuned resonances. Ideally it would be nice to be able to get a radial resonance going inside of Jupiter so that the pressure waves go directly down into the core and then bounce off each other creating amazingly high pressures at Jupiter's core while leaving the devices actually causing the sound waves in relatively safe and low pressure environments near the surface of the planet. How exactly these sound waves are to be produced is a matter for a future post. Also I would be willing to bet that the simplest radial standing wave pattern resonance is not stable and one would have to design something with a little more robustness.

I can has comment?
yes I understand the vile thing I am doing in introducing lolcat syntax into my blog but I wants me some comments. Tell me how horrible I am for making such an attrocious mistake. Slander pickles and grapefuits or people who read new scientist. Just please leave me some comments. Of course if they happen to be vaguely topical that would be lovely and if it is a question (preferably one I know the answer to) awesome! I know you people are reading my blog... well I know that at least one or two people visit it a month... so this is a cry for some feedback. Please leave me some comments! Plus if I can trick you people into investing yourself in the blog enough to leave a comment that has to lead to increase future reading (and also increased posting), which is probably bad for you but good for me.
