Measuring Emotions

Hi folks,

It's been quite a while since I have posted on here. I have been terribly busy with work, SCHOOL and other duties that I have here in the big city (and other places). So let's have at it.

 Quite recently Affectiva, a group of MIT collaborators, has come out with an amazing little device. It is able to measure some emotional responses. It is called the Q Sensor. How can such a device be able to measure something subjective like emotional responses?

Well first off, it comes in wrist band form. Thus, it is constantly touching your skin. The skin has many mechanisms for many different types of emotional stressors. For example, when you are nervous, you start to secrete sweat. When one is excited or stressed, there is a slight electro-gradient that is created. This can be measured by the Q Sensor! It is the change in charges on your skin that the sensor picks up on. 

This device has many features, like being able to be hooked-up to a computer (via USB). There is a button on the device to mark times of significant events (like giving a presentation). 3-dimensional motion sensors to monitor how you move, and enough storage to keep logs for up to 4 months of events.

This is great for many Health Care professionals. Care givers can prevent stressors on their patients by monitoring the activities the Q Sensor picks up on. Preventing major stressors will help prevent some forms of cardiac arrest and other ailments. Once we know what stresses a person, we can help them calm down by doing other activities (meditation comes to mind). It can also help monitor sleeping patterns. The data can help understand when people with sleeping disorders are awakened and figure out how or why this event occurs.

This device will help with the understanding of some emotional responses. I believe these types of devices will help with  further explanations of ideas in consciousness.

Elevator to Emptiness?

Hello dear reader. Today’s topic has been one that I have questioned a long time ago, and then forgot about it. Quite recently my housemate has shown me a cool internet tool called “Stumbleupon.” Even more recently, I stumbled upon a site that talked about the topic of Space Elevators.

So the goal for the space elevator is quite obvious. We are looking for an efficient method to travel back and forth, to and from the Moon (and other planetary bodies). The proposed method is using nano-carbon rods (these are quite strong and hard to break) to make a cable and then attach it to the moon. From this plain description, you may have found the problem. “Let’s attach this cable to an orbiting body!”

If we attach such a thing to an orbiting body, there will be adverse effects. When you attach two bodies, especially one that orbits the other, you are changing the orbiting pattern. Thinking about it, we would probably create something like a binary system. There is no real solution for that, except not to create such a device. Earth has more mass, thus, we would be swinging the moon around, which could probably knock it out of its original orbit.

As the moon is a key factor to the tide of our oceans, there could be some very adverse effects concerning our oceans. Fishing will become harder in some areas and easier in others. Sediments would be harder to for with heightened activity. Think of the “natural” disasters that would occur; Floods that seem to get stronger.

Depending on the placement of the cable attachment, we would be creating an artificial “North” and “South” pole. A new axis as to where it spins. This would change the speed in which the moon rotates. Moon gazers would notice that the dark side of the moon appears less often and the waxing and waning process is a lot slower, if not null.

We are going to find a different way to travel back and forth to parts of the solar system. We would be easily be destroying one of the only visually pleasing objects in the sky that people can see, even in light polluted areas (such as Toronto).

21st Century Lunatic

Hello Reader!

Today is a great day! It was beautiful out, the sky shined so bright. It was just an superb day.

Anyways, I have been given a challenge. Not quite me specifically, more of a broad thing. My brother posted on his wall "Write a letter to someone from the 19th century trying to explain an aspect of 21st century daily life. Guaranteed, you can't explain Facebook without making us all sound like lunatics." I am going to accept this challenge. 


Where to begin... I know! The fundamentals of Science. In this era, we had knowledge of (or on the way depending on the year) electricity, the battery, and electrical circuits. By the end of this century, we had a grasp of Alternating Current (Thank You Nikola Tesla). They were on the edge of everything big in the world of electricity and magnetism. Even in the last years of the century, Guglielmo Marconi created the first wireless communication device, the wireless telegraph.


So for those folks still stuck in the year 1897, here's what  Facebook is.


First we must introduce the computer. In a nutshell, a computer is an object that contain many electrical circuits that carry electrons (we know about electrons by now). These electrons carry numerical values of 1's and 0's. The 0's and 1's translate to information that can do math, which can determine output like colour, text, math equations and even sound. This is the basis of the computer. Many computers (or just one) can make something called a server.


In the 1960's the first unofficial model of the internet was used by the United States of America (Yes, the colonies survived and thrived!)  The internet is a network of computers, like that of neurons (you had the knowledge from Franz Nissl). Neuron are connected to send information back and forth from one neuron to the other. The internet uses the same concept. We are able to send information (via wireless electromagnetic waves or from electrons) from one computer to another. In recent years, the internet has been open to the public to use and abuse.


The internet runs on an IP address. An Internet Protocol address give the specific location of the computer/server. Sticking with the Neuron idea, it's like locating a specific neuron in the brain or anywhere in the nervous system. From there we have web pages.


A web page is like a brochure. Most of them are made with information that help you. Some websites are made to entertain. The difference is that a web page can be mutable. I mean it is able to have an interactive component, like playing a game. Word are able to be moved around. This brings us to Facebook.


Facebook is a web page in which people post what they like and what they don't. What is going on in their life and what they wish would. It's like writing a letter (in only a few words) to all your friends and they will understand whether you are happy, sad, angry or just plain crazy. You are able to talk with your friends from long distances (think wireless communication).


This is what Facebook is in a nutshell.

Problems with Time Travel (PT. 1)

I know I have broken my New Years promise, everyone does it though, so get over it. I know this is the first post in over a month and this one will be kept short, in order to study for my exams (I have one tomorrow -_-)

This topic has come from a quiz I was looking over to help study. Light was traveling faster than light. So I immediately thought about time travel because something that travels faster than light, is said to be able to travel in time.

So what happens if we build a machine that is capable of traveling in time but the actual machine doesn't move? I became quite curious and came up with this postulate. If the machine is stagnant and travels back in time, then it must exist at the same spot, at all times. That is, if it travels back in time to an era before the invention actual was constructed, then it must stay in that place for all time in between.

For example, this time machine is built in 2020 (this is highly unlikely) and I want to travel to my birth year. I will end up in the same place but on the date of my birthday. Where should this machine be built, because the past didn't have access to it? Also, think about this, if built in public, how would the population respond to you sitting in this machine traveling back in time? What if you got shot while on the machine right before the crowd disperses (or while just assembles by your point of view), when would it happen? Near your beginning of the travel or near the end?

As I said this is a short post and hopefully thought-provoking.
