Shielding Fails!

Continued discussion of subspace physics.

Subspace is an odd set of the laws in our dimension, specifically it is missing the electromagnetic force, or half the electroweak interaction. This means that things that rely on that interaction in our dimension fail spectacularly in subspace.

Shielding against this affect is the most important part of a functioning subspace disc after the transitions into and out of subspace. The disc is a carefully arranged array of projectors that are encased in a titanium-doped mono-ceramic, capable of withstanding rough use. Only voltage difference need be applied over the arrays, meaning that only two wires enter and deliver the current to the array. Of course the shield produced by the disc isn't generally referred to specifically, as shield generally refers to electromagnetic deflector arrays mounted on some ships.

When shielding fails, the matter inside the previously shielded space loses all electromagnetic attraction. It completely ionizes eve…

Sub-space Equations: Drift and Pointing

This post is continued from the previous one, talking more about depth and a bit about velocities.

Generally a well pointed ship will come out tangential to the orbit of a gravity well, and fall into the correct orbit with only minor modifications. Of course if it comes in perpendicular it could cause the ship to quickly fall to its destruction, or be at an escape velocity on the other side of the gravity-well pointed away from the mass.

But there are a few problems with traveling in subspace, other than getting your heading just right. There is drift. Drift causes a ship to essentially lose depth in subspace, meaning that potential energy in our universe is lost.
Where po is the starting depth and 256 is a conversion variable related to a light year and deltaD is the distance traveled in light years. This equation hits about 0 depth in 32 light years, this causes ships to pop out of subspace with 0 potential energy, essentially an energy vacuum. If not deeply inside of a gravity well…

Sub-space Equations: Velocities and Depth

As promised from the previous post: Equations.
First let's start with an equation describing the relative velocities between normal space and subspace.
Where K is the constant of about 8.24x10^23 kg^-1m^2. v_n is the velocity relative to all influential gravitational bodies, depending on the precision needed. The more precise this needs to be the more bodies need to be considered, such as for sensitive instruments going into subspace to observe anomalies. If it is an emergency or the computer power is limited, which in this time period would probably mean there was also other emergencies, less n bodies can be used. Of course if the right bodies aren't considered it can be catastrophic in when a wrong exit point is determined.
The second equation calculates the "depth" that the system will enter into subspace, or the potential energy.
Where G is the gravitational constant, m is the masses of objects and d is the distance from those masses. With further posts I will g…

Fun Physics and Fiction

Time is the enemy. Dramatic events are unfolding, but will our hero be able to save the world, yet again, in time? Used to dramatic purpose time is a very useful tool as there are very few people who haven't been up against a deadline, real or constructed. They can feel the tension building, the expectation of succeeding slowly winning out over defeat or receding as panic sets in. Split seconds described in paragraphs that take ten times as long to read than to happen in book time.

Time can also be used dramatically in a longer term view in science fiction. Where will we be in so many years? Time travel is another way, and then there are the books that stitch together star systems with relativistic travel, decades long travel between stars and everybody that you knew when you headed out is long dead and hundreds of years have passed. To me it is depressing, or rather actually scary. When we travel on Earth we get those same affects, but since we are no where close to the speed of …

Jobs, Again and More

Probably the hardest thing to do from Hilo: track down a job on the mainland, and get hired.

So if you know anyone with a software position open and willing to hire me, then let me know. In the meantime let me talk about something else. I believe earlier in this blog I have mentioned how much I used to dislike writing for a class, but how much I enjoy writing outside of class. Well it's sort of like data and my post about subways really culminated a few of those into one. I definitely didn't have much trouble with the writing, just some of the code kept me boggled for longer than it should have.

I really do like writing, must have gotten it from my mother: Bird Banter, and her companion gardening column with a few less years: Garden Gossip. I really like quite a bit of science fiction as well. I really enjoy hard science fiction where there might be far out concepts but the author integrates them into the story, possibly using a new concept to turn a bit of the plot around. So…


So we really haven't been fencing much. I think I will have to read my own posts on fencing before getting back into it. We have a really odd schedule right now that is coming to an end come the end of this month. In the meantime we have picked up archery.

Isn't that just another expensive sport? Well, sort of.

We started getting interested as I usually get interested in sports. One of our friends was trying it out and I went to the indoor range to find out what the atmosphere about it was, and if it was any good. I've done archery in scouts, but hadn't really thought about it except in passing. So I went.

Managed not to kill anyone despite the fact that I got an arrow to bounce back to within a few feet of the line. But it was a 70 lb compound bow, not my cup of tea. So I went and hung out more to watch and learn, but my friend stopped coming. That's how it's happened for all but table tennis: Someone introduces me to a sport and then immediately gives it up.

Progress Stunted

As a modern man, and a person living in our world I understand the need for tolerance, but of what should we be tolerant? And where should we draw the line?

Tolerance is along the same lines as endurance. There are many things which we must endure day-to-day, year-to-year, and through the generations.

When someone needs to live somewhere for a job or just because they can't get away (or wants to live there, but that is outside of this consideration) they must tolerate the weather. Snow, ice, cold, rain, heat, drought and many other conditions that we must live with. What do people do with the weather?

First they tolerate it and buy appropriate clothing, coats, hats, shorts, whatever would make walking through the weather more tolerable. This is a terribly important step that many animals don't have the luxury of, in fact it is why humans can survive in such varied conditions, even those who are acclimatized to Hawaii can make do with a few extra layers farther north.

To Take or Not to Take the Subway

Introduction to Data Science CapstoneUdacityThe New York Subway system spans 842 miles of track with 468 stations and transports about 5 million people a day. But those are just large numbers, first we need to get a feel for the data. What does the precipitation look like throughout the year? What does the ridership look like on an average day? Can we predict ridership with the given information?
The dataset I am using to answer these questions is turnstile data from 2013 collected over the entire city, however, I am limiting mine to the most consistent station for reporting data: Wall Street. I also signed up for an API on Weather Underground to get hourly data for the same year. Let’s take a look at precipitation throughout 2013.
This graph has all 365 days of the year with the precipitation of each hour arrayed along the horizontal axis. The alpha of the dots shows us the intensity of the rain in the hour. The most intense rain in an hour recorded 1.06 inches. Given that information …
