# Month: May 2016

## My New Math Project: Calculus

Now that I’ve let the whole world know this, I *have* to follow through on my plan. It is difficult to embarrass me, unless I deliberately set up a situation that uses embarrassment on a global scale, as a self-motivational tool, and that’s what I am doing right now. I fully intend to learn calculus in June, and this will help.

I already have books, and a plan of attack. I am not working for pay in June, nor taking any classes, so that gives me the time, and you can’t beat a tuition-price of zero.

The key was moving calculus from my mental “incomprehensible” Venn diagram bubble to my “I can do this” Venn diagram bubble. I never should have created that “incomprehensible” bubble in the first place, but it took a lot of time (30 years or so) to figure that out.

Update, 14June2016: I have decided to turn this from a project for the current month into an ongoing project . . . for the rest of my life.

## Proof: An Infinite Number of Irrational Numbers Can Be Found Between Any Two Rational Numbers On the Number Line.

[This theorem was proven long ago, in other ways, but this is my way to prove it.]

Let x and y be two rational numbers on the number line. Since both x and y are rational, both x and y can be written as fractions. All fractions, when written in decimal form, either terminate (such as ¼ = 0.25) or form a repeating pattern (such as 1/3 = 0.333…, repeating). To find an infinite number of irrational numbers between x and y on the number line, simply write both x and y in the form of decimals, and then follow the decimal expansion until the two digits no longer match, as is the case for 0.1111172 and 0.1111173, which match each other, up to the digit 7 in the millionths place, but no further. To generate an infinite number of irrational numbers between x and y, simply examine the part of the decimal expansion of the smaller of the two numbers, x or y, which does not match the other number, and randomly jumble up all of the digits (including trailing zeroes) of the smaller of the two numbers, x or y, after the match-point, changing these digits as well (in random ways), which will result in the creation of an irrational number between x and y. Since there is no limit to the number of decimal places a number may have, this may be done in an infinite number of ways.

[I have now fulfilled my ambition to use the phrase “randomly jumble up” in a formal proof.]

## On Peace (Thanks, Mom)

I am posting this to make one fact obvious: I want my blog to be a place where believers (of various types), and non-believers, can interact peacefully. There is a need for such places. This is one of the things my mother taught me.

## A Zome Torus, Before and After Adding Dodecahedra, As a Model for a Pulsar’s Accretion Disk and Radiation Jets

I’ve been using Zometools, available at http://www.zometool.com, to build interesting geometrical shapes since long before I started this blog. I recently found this: a 2011 photograph of myself, holding a twisting Zome torus. While I don’t remember who was holding the camera, I do remember that the torus is made of adjacent parallelopipeds.

After building this torus, I imagined it as an accretion disk surrounding a neutron star — and now I am imagining it as a neutron star on the verge of gaining enough mass, from the accretion disk, to become a black hole. Such an object would emit intense jets of high-energy radiation in opposite directions, along the rotational axis of this neutron star. These jets of radiation are perpendicular to the plane in which the rotation takes place, and these two opposite directions are made visible in this manner, below, as two dodecahedra pointing out, on opposite sides of the torus — at least if my model is held at just the right angle, relative to the direction the camera is pointing, as shown below, to create an illusion of perpendicularity. The two photographs were taken on the same day.

In reality, of course, these jets of radiation would be much narrower than this photograph suggests, and the accretion disk would be flatter and wider. When one of the radiation jets from such neutron stars just happens to periodically point at us, often at thousands of times per second, we call such rapidly-rotating objects pulsars. Fortunately for us, there are no pulsars near Earth.

It would take an extremely long time for a black hole to form, from a neutron star, in this manner. This is because most of the incoming mass and energy (mostly mass, from the accretion disk) leaves this thermodynamic system as outgoing mass and energy (mostly energy, in the radiation jets), mass and energy being equivalent via the most famous formula in all of science: E = mc².

## On Destroying the Universe (with Mathematics)

No cause for alarm here; it’s not going to happen. I promise. Now, please, stop worrying about this, if you can. I’m not trying to scare anyone.

If *not* worrying about this proves to be difficult, simply consult a mathematician.

## Asperger’s Syndrome and “Emotional Vision”

The source of the term “emotional vision” is the same as the source of the image above: this New York Times article. This blog-post is my response, so I recommend reading the *NYT* article before you continue.

The story was written by, and about, a man on the autistic spectrum, and, if you’re on the autistic spectrum and get published in that newspaper, you’re high-functioning. High-fuctioning autism (HFA) and Asperger’s syndrome were “merged” in the United States in 2013, shortly before I started figuring out that I am, myself, an Aspie. By the time I discussed the idea with my doctor, it was too late to get an “official” diagnosis. (Yes, that does mean no diagnosis for me, but that’s simply the way things happened, and I’m fine with that.)

Many in the Asperger’s community have a form of emotional blindness — an inability to “read” the emotions of others — and that described me accurately until, well, this week, when I awakened my own emotions, and also gained the ability to understand emotions of *some* other people. Which people? Only the ones I know well, generally by having contact with them for at least a year. Shortening this time is high on my mental “to-do” list.

In the article linked above, the author voluntarily had his emotional light-switch “turned on” in an experimental treatment designed *by other people*. That, I believe, is the key difference between his case and mine, for I made the decision to turn mine on myself, wrote the “mental software” behind it myself, and am testing it at every opportunity, in accordance with the way I think. This ability to reprogram my own brain’s software isn’t magic, nor a super-human ability power, but simply a project I have been working on, for, well, over thirty years.

The author of the article above has many regrets about accepting the experimental medical treatment he had to turn his emotions “on.” This treatment involved letting doctors mess around with his brain. My own doctor knows me well, and therefore does not try to force any sort of treatment on me, for he knows that my biggest compulsion involves an intense need to be free from control by other people. Not all Aspies have compulsions, but some of us do, and I am one of them.

Something most Aspies *do* have are “special interests,” as they are called, but they vary widely. My special interest is mathematics. I learned to speak, read, and write so that I could express my own mathematical ideas. My parents provided me with books about mathematics, one they realized the intensity of my need, driven by curiosity, to absorb mathematical ideas which were new, at the time, to me. I have never stopped wanting more.

My interest in science came later, but not much later, due to that same curiosity. Once I learned how linked the physical sciences and mathematics are, this was inevitable. The more mathematical a given subject was, the faster I could learn it. Without mathematics involved, however, learning was a chore, and deciphering the mysteries of human behavior has been, for this reason, very difficult. Why did people do such bizarre and confusing things? For a long time, I had no idea, and wasn’t willing to do the hard work of figuring it out, either. I puzzled other people, and they puzzled me right back. I made little progress, on this front, for many years.

Why did understanding anything about emotions come so much later in life, for me? That’s an easy question to answer: emotions are more complicated than anything else I have learned, in the sense that emotions are extremely difficult to understand, or express, mathematically. To do this in a way that would work well, I had to rewrite my “software” myself, and that took a lot of hard work, time, and thought. This is entirely unlike the case of the man who told his story in the *New York Times*, who was thrown into an emotional nightmare by an experimental treatment he willingly received, but did not design. He has my sympathy, and I hope his life gets better in the future.
