MONSTERS OF DEPRESSION

The first time was the worst.  They came in the middle of the night without warning or reason, waking me from a deep sleep. Monsters made of 100% raw negative emotion appeared and had taken over my head. There were 4 of them: boredom, poison, anxiety and doom, each connected and feeding off the others.

They were foreign, relentless,  emotions without a cognitive trigger that couldn’t be explained or rationalized away.  Personal foundations of religion or using logic were useless in fighting them.  There was no escaping through sleep, drugs or alcohol, even for a second. So strong, they took away apatite and caused trembling, diarrhea, and vomiting.  At their strongest surviving more then a couple of days would not be possible.  So much worse than I ever imagined hell could be like.  It felt like they were not from this world and I feared they could even follow in death. 

Boredom was the biggest and worst of them all, 1,000 times stronger than any boredom I had experienced before.  Poison was next, taking away any joy from doing things I normally like and replacing it with even more bad feelings, adding to the already unbearable boredom.  Anxiety from not being able to get away from them kept me from sleeping or resting and doom convinced me things were going to get worse.  Time slowed and all my thoughts were consumed with trying to fight them.

The first attack over a decade ago slowly eased a few days afterword for again, no apparent reason leaving me forever changed.  I’ve felt them every day since, some days more than others but never near as bad as the first time.  Always lurking in the shadows, leaving me never knowing if and when another full out attack may happen.

THE SOLUTION TO SAVING THE ENVIRONMENT

The biggest threat to the environment is rarely talked about and easy to fix but unless it’s addressed soon, nothing else we do will keep us from destroying the planet.

The damage we do to the Earth is simple math. The size of the average persons carbon foot print, times the number of people on the planet. Since 1970 the worlds population has doubled. At the present rate kindergarten students today will see it double again in their lifetime, doubling the damage we’re currently doing to the planet. If left unchecked a generation later will see the Earths population double again making are carbon foot print 4 times what it is today, and so on. Just look around and you can see how fast cities and towns are expanding.

As we sit on the tipping point of catastrophic disaster even if the population stopped increasing today we would be lucky not to loose this game of Jenga we are playing with the worlds ecosystem. Left unchecked we will soon realize all the science, carbon taxes and government policies in the word won’t put a dent in fixing the damage done by this rapid population growth.

Even skeptics of climate change can’t ignore the logistics of providing enough food and energy for a world population multiple times larger then todays not to mention dealing with the waste. The more the worlds populations grow the greater the threat of conflict between nations over resources.

Having children is one of the most fulfilling and important parts of being human and no one has to give that up to save the planet. If every couple had an average of 2 children the worlds population would stop growing and become neutral, that combined with current programs and scientific advances might give us a chance at survival.

There is no time to waste. “World population” needs to be at the top of the list for combating climate change. The people of the world need to understand that controlling population growth is the only thing that will save us. Only then will governments be able to to make it work by phasing in policies like eliminating child tax breaks for large families. Changing current values will not be easy and it will take brave politicians with our support to implement the policy’s necessary.

A slowing growth in population will also effect many other issues. Although it would solve some problems like easing the housing crisis and transit problems it will also most likely have a negative effect on the stock market and countries with deficit based pyramid type economy’s.

We can no longer foolishly believe electric cars, carbon taxes, recycling, bicycling, and renewable energy will save the planet. Until population growth is brought under control, nothing else we do matters. Effects of biblical proportion from are actions are no longer generations in the future but will be felt within your or your children’s lifetime. After reading this, It is now up to you to do your part to help save the planet by getting the word out about population growth, through friends, school, work, social media, political lobbing or simply passing on this post. People are already beginning to focus on the science behind climate change but it is much more important to focus on the math.

POLITICALLY CORRECT INJUSTICE

 

In the Canadian National News today, yet another high profile man is accused of sexual misconduct.  Despite no charges being laid by police, meager checking of facts, and an anonymous accuser, he is immediately fired from his job, and publicly disgraced.  Decades of hard work building a remarkable life,  gone in an instant.

In our hast to correct some long standing politically incorrect (or “PC”) social injustices, innocent until proven guilty in a court of law has been replaced with trial by media.   If that’s not bad enough, competition for viewers is driving even the most conservative media outlets to alter context and omit facts to sensationalize a story.  The result is a toxic culture that takes away the basic rights of the innocent.

Sexual misconduct and the “me too” movement have become the latest PC topics, it along with racism and discrimination often disproportionally dominate the news.   On Jan 12 in Toronto, despite a student being murdered on his way home from school it was a racism story about a girl claiming to have her religious clothing cut by an unknown attacker that headlined the national news.  All levels of government including the Prime Minister were quick to comment on it, condemning the attack and the person that did it,  vowing to use all resources available to quickly apprehend the perpetrator.  A few days later, after proper investigation by police it was found to be a hoax and never happened.  Luckily in this case an innocent suspect did not have their life ruined.

Other ways we try to correct injustices are also questionable but not so obvious.  In 2015, Our Prime Minister, Justin Trudeau was elected on a platform of being politically correct and fairness for all Canadians. In an effort to make government more fair and appear less sexist he set out to appoint his cabinet of being equal in gender, 15 men and 15 women.   Instead of appointing who is most qualified regardless of gender, he chose to correct a sexism problem with sexism. Hiring someone for the sole reason they are a women is no different then not hiring someone for the sole reason they are a women.

When it comes to some PC injustices “We will not tolerate it” is an expression frequently heard.  It is this intolerance that is taking away our basic right of freedom of speech through fear.  In a recent Facebook post, following a list of legitimate political concerns was written “Have the guts to repost this?”.  Their are some that will call this article sexist or racist for merely criticizing the unfair methods we handle these PC injustices.

Aside from promoting hatred, it’s important for everyone to feel free to express their opinions.  Changing sexist and racist views can only be done with dialogue, not condemnation.  The only thing worse then “sexist and racist views” is suppressed “sexist and racist views”.  I can’t help wonder if, and how much, suppressed views of how politically correct  problems were dealt with in the US contributed to the election of Donald Trump.

Let me make it clear, sexual misconduct, racism and discrimination are not only big problems in society today but in many cases a crime. They should be treated like all crimes and reported to police.    After a proper investigation if enough evidence exists, charges should be laid.  Injustices that are not against the law should be dealt with through litigation in the courts and be reflected  in future laws.  Its important to realize that changing peoples opinions can not be forced overnight, especially when unfair means are used.

As we struggle to find new ways to correct the unacceptable injustices that remain between us and a fair society for all, we need to make sure that by taking a step forward we are not taking 2 steps back.

UNDERWATER TOWABLE DRONES

Imagine skimming just above a lake bottom, exploring underwater terrain that’s never been seen by anyone before, all without leaving the safety and comfort of a powerboat.  Virtual reality goggles give you the feeling of being right on board the drone and the joy stick control puts you in the pilot seat.  As your powerboat pulls it along faster then a diver can swim, it records the changing water depth coming up and displays it on the VR screen.  All the action is recorded on an SD card in 360 video along with latitude and longitude so you will know the exact location of any treasures you find.

I came up with the idea for a towable underwater drone while seaching a lake bottom for an outboard motor that had gotten loose and fell off the back of a fishing boat.  The search area turned out to be much larger than anticipated.  Although the water was just 15 feet deep, visability was only 8 feet and the bottom could not be seen from the surface.  After a half hour of searching and my air tank half empty I had an idea.  To cover more area, instead of swimming, have them tow me with a rope behind the powerboat.  It worked so well I thought about it more and came up with the idea for a towable underwater drone.

Unfortunatly towable underwater drones don’t exist yet but could be built with today’s current technology.  Heres the rest of my idea with more details.

THE BASE:  The base unit contains the complete system that quickley connects to a permanently mounted bracket at the stern (port or starboard side) of any powerboat.  A storage compartment on the base contains VR goggles, a wired joy stick, and a cable with alligator clips that connect to the tow boats 12V battery for power.  A small rechargable 12V gel cell battery is also contained in the base for emergency power.  On the back of the base a depth finder is mounted at the end of a telescopic shaft that extends into the water.  The base also contains a gps, computer, electronics, and reel of 200 feet of tow cable that also provides power and data transfer for the drone.  The boom keeps the drone and tow cable clear of the boats motor and propeller.

HOW IT WORKS:  The pilot attaches the wired joystick control to any smooth surface by suction cups in a position thats comfortable to use and turns on the main power.  When the boat is in the desired area the pilot puts on the VR goggles connecting him to to the drone’s 360 degree camera via blue tooth conection with the base.

As soon as the drone is lowered by its cable via the joy stick middle finger switch, the camera and headlights turn on, video from the drones camera is sent to the VR goggles video screen, and recording begins on the memory card.  The 360 degree camera and VR goggles give the pilot the ability to look left, right, up and down in real time.  With the boat moving forward slowly, the pilot pulls back on the joy stick (to keep the drone on the surface) and continues to unwind tow cable until the drone contacts the water.  With the drone skiping across the surface the pilot continues to let out aproximately 100 feet of cable.   The base computer continuously records the depth of the water between the power boat and the drone and displays it as a “bottom profile line” on the VR goggle display.  This allows the pilot to know the depth of water where the drone is as well as any obstacles or depth changes 100 feet ahead.

The digital proportional joy stick is conected to the drone through the base computer to create a fly-by-wire control system.  Two servos in the drone control up/down and left/right respectively to create the following functions:

  • Pull back to go up
  • Push forward to go down
  • Move left to go left
  • Move right to go right

Information from the “water speed sensor” on the drone is sent into the base computer to determine the ratio of movement of the drone’s control surfaces to joystick input.  The computer will also override joystick input should depth sensors on the tow boat or drone indicate imminent impact with the bottom.  These 2 fly-by-wire features allow for both safety and ease of control by new/inexperienced pilots.

Video is sent from the drone’s low light 360 degree camera to the base computer through the tow cable.   The following overlay of information is added to the video before being sent by blue tooth to VR 360 degree  goggles:

  • Drone Depth” from depth guage on drone
  • Bottom Depth” from depth finder on drone
  • Speed of Tow Boat” determined by base’s GPS
  • A “Bottom Profile Line“, created from the base’s depth finder data, the line shows a profile of the bottom between the drone and the tow boat. This aids to warn the pilot in murky water and high speeds of sudden depth changes and obstacles coming up.  It also shows the drone’s position in relation to the bottom.
  • Distance to Tow Boat” (same as the length of bottom profile line being displayed).
  • Latitude and Longitude” of the drone.  The base computer uses the GPS of the base unit and calculates direction of the tow boat, length of tow rope, depth of drone and left/right angle of the tow cable leaving base unit to get the actual latitude and longitude of the drone itself.
  • Current “Date and Time” with seconds
  • REC” indicating video is being recorded
  • The following warning messages are displayed only when applicable: “BACK UP POWER” when power from the tow boat is interrupted and base has switched over to the back up enclosed battery / “LOW MEMORY” when the memory card used to record the video gets close to full / “COMPUTER OVERRIDE” when computer takes over joy stick control to prevent impact with the bottom.

Any number of blue tooth VR goggles can be synced with base allowing passengers in the tow boat to feel like passengers on the drone.  Independent signals allow everyone to look different directions at the same time and help ensure the pilot dosen’t miss anything interesting.  A button on top of the joy stick enables the pilot to take a still photo of anything he sees thats interesting.  All the information including longitude, latitude, date, and time is captured on the photo making it easy to go back through the video and play back the same location later.

When ready to return, the pilot squeezes the cable in button with index finger on the joy stick and the electric motor in the base winds in the tow cable. When the drone makes contact to the docking conection at the end of the boom, power to the drone is shut down, lights and camera turn off, and a data folder is written to the memory card.  The folder is named “the date and time the drone left the docking connection” and contains a video file of the whole trip and a seperate file with any still photos the pilot took.  The video can be played back later with any VR goggles making it possible to relive the experience over and over.

An App. for a tablet could also be created to work with the base’s GPS to do a grid search.  Enter 3 or more GPS points to form a search area along with the bottom water visabiliy on the tablet App.  The GPS on the base unit sends information by blue tooth to the tablet enabling the App. to provide a line for the power boat driver to stay on so the entire search area is visually covered by the drone.

Towable underwater drones would combine the thrill of being an explorer with the fun of a video game.

IS RACISM THE PROBLEM? STEREOTYPING AND WHY THE DIFFERENCE MATTERS.

These days, racism is considered one of the biggest problems in the world.   Ignorance they say is the cause, but maybe the greater ignorance is our refusal to study and better understand what has become a very delicate issue.  I have a hard time believing there are still that many people in Canada that think one race is superior to another.  Is stereotyping being confused with racism?  What if stereotyping was the cause of the majority of acts we considered racist?  What if there was a way to change it?

First we need to understand the difference between the two.  Racism is defined as the idea that one race is superior to another.  Stereotyping is a preconceived notion about a group of people based on an individual’s experience with that group.

What if racism is learned and reinforced through culture and upbringing?  No question, racism was a huge problem in Canada during black segregation back in the 1940’s.  Also a strong example that shows how the power of the cultural environment we grow up in can blind us in the way we think.   On the other hand, what if stereotyping is not learned through culture but rather a natural learning function of the human brain?  I’m not saying racism is still not a problem, but how much of what we consider racist today is actually stereotyping?

Imagine you are walking down a dark secluded street alone.  You hear someone coming up behind you fast.  You turn around to see who it is.  If given a choice, of the two men below, who would you rather it be?

If you said it doesn’t matter, and you are being honest with yourself, congratulations, you are not guilty of stereotyping.  For the rest of us that probably picked the guy on the right, ask yourself, why?  In most cases it comes down to the way they are dressed.  Our brain stereotypes the type of people they are by using limited personal knowledge and experience of the kind of people that dress that way.  But the fact is, the guy on the left could turn out to be the friendliest person you have ever met and the guy on the right could be carrying a gun and out to rob you.  Even if we’re aware that we are stereotyping, most people can’t help feeling more frightened by the guy on the left.  Evidence that shows how stereotyping can reach deep into our subconscious.

Stereotyping doesn’t just apply to how we dress it also can be on what kind of car we drive, our mannerisms, how we talk, where we live, our jobs, practically everything.  There are even forms of accepted stereotyping such as car insurance where premiums are partially based on stereotyping by age, gender, and where we live.

If the human brain stereotypes in so many different areas, is it not logical that it does so with culture?  Most people won’t admit they may still stereotype cultures in fear of being called raciest.  However, try searching “comedians stereotyping” on You Tube.  Comedians, usually of stereotyped minority groups, can still make jokes that would be considered racist and not tolerated coming from anyone else.  Did you laugh?  Does laughing mean you identify with it?

Every country has its own unique culture.  Does our brain actually stereotype against race, or the culture it associates with that race?

If two families from different races and cultures adopted babies from the others race and culture, what stereotypical cultural values would each of them have when they grew up?

Once learned over time, cultural values can take years, even generations to change. Here in Canada, this coupled with a high amount of immigration, helps to bolster cultural stereotyping.  Its not just cultures of foreign countries that are stereotyped,  micro cultures within Canada also exist based solely on demographics.   Whether you were brought up in the country, city, or a specific province, everyone is stereotyped.  The most extreme micro culture is in the bad areas of cities, often with high crime, gangs, drugs and violence.  It is these areas that seem to be the biggest problem with stereotyping culture being confused with race.

So how do we fix it and provide a better equality for all?

Stereotyping itself is bad enough but the greatest injustice happens when someone has prolonged exposure to only a small negative part of a culture and their brain stereotypes it to the entire culture.

For the last 2 years it seems every second night on the news they broadcasted a Muslim terror attack somewhere in the world.  For people that have little or no other contact with Muslim culture it has built up a deep rooted negative stereotype.  Suppose on the news, for the past two years instead of a terrorist attack, they only had stories of the many positive things in the Muslim culture.  Would Muslims have a positive stereotype?  I’m not saying to change the news but to understand the effect it has on people.  What would happen if when the news broadcasted a terrorist attack, they also made a point to also include a positive story on Muslim culture somewhere in the same broadcast?  Would that subconsciously reduce a build up of negative stereotyping?

Law enforcement and stereotyping is also a big problem both within Canada as well as other Countries.  When officers constantly work the same bad micro cultural areas that are predominantly one race,  it’s understandable how a stereotype of that culture can be mistaken with race.  What would happen if they alternated, working one week in a bad micro culture area and the next week in a better micro cultural area containing people of the same race?

Understanding and more research on how the brain stereotypes is key.  The more we understand on how the human brain stereotypes the better the solutions we will come up with to create a more equal and fair society for all.  If stereotyping is shown to be a natural process of the human brain that extends into our subconcious, treating it like racism and calling it ignorance, condemning it and assuming it will go away isn’t the solution.
